Note

I know you probably have no idea, but you're the only person I know who is also into this stuff, and there's no info online. because mammals have basically the same hair color genes, would human hair colors be analogous to cats? black=default, brown=chocolate, blond=either cinnamon or some type of dilution, red=red (phaeomelanin replacement)? I know piebald and temp. sensitive albinism actually exist very rarely in humans too

Red is an mc1r mutation, i know that (like amber in cats). Wait a minute, I'll try to look around...

So. uhh.

We identified 123 autosomal and one X-chromosome loci significantly associated with hair color; all but 13 are novel.

via https://www.nature.com/articles/s41588-018-0100-5

Wow, that was an exciting article. Look at this for example:

First, the observation of higher prevalence of lighter hair colors among women follows previous findings based on objective quantitative measurement of hair color, suggesting that sex is truly associated with hair color, independent of socially driven self-reporting bias.

Light hair colors (blonde and red) are more common among women. Very interesting.

Anyway unfortunately human hair color seems to be very polygenic. Here's another good article i found, with even more genes: https://www.nature.com/articles/s41467-018-07691. They describe at least 16 MC1R variants associated with red hair with different penetrances, and found related mutations on several other genes too, including POMC and RALY (the latter influences the expression of ASIP, a familiar peptide: this is our very own agouti gene, responsible for melanistic morphs in several species). On the other hand the variants of genes HERC2 and OCA2 seems to be associated with blonde hair and decreased probability of red.

Unfortunately despite all of this, MC1R mutations ≠ red hair:

Although 93% of individuals with red hair carry two MC1R variants, these make up only 15% of people who carry two MC1R variants. The majority of people with two variants have blonde (15%) or light brown hair (41%).

And this is still just red. Every other color is even more complicated. The authors made a genetic score value to predict the hair color on the blonde vs brown vs black scale based on 213 gene variants.

These include mutations of the genes TYR and TYRP1 - respectively C (color restriction) and B (brown) in cats -, EDNRB, a gene associated with (i believe) roan-type colorations in different animals, and KITLG or KIT-ligand, a gene (based on the name) working together with KIT (responsible for white spotting in cats).

So all in all: i wouldn't say brown or blonde hair in humans = chocolate or cinnamon or anything else in cats. Even red hair as the equivalent of cats' MC1R-type recessive reds is a little bit of an oversimplification.

The closest analogue our hair color varieties have in cats is probably... rufousing.

#ask and answer #so sad humans don't have agouti hair #it would be so fun #stripy hair #humans #rufousing

Me IRL: Do I have plans today? I know I have work......yeah that's it, oh well, I'll just do whatever comes my way

Meanwhile me in potion permit: Ok 6 o'clock, if there are patients in the clinic treat them first, then head down and dig up the worm in front of Mayor Myers house. Next, teleport to the wilds and head down to Mattheo's house and dig up the second worm there. He wakes up at 8, talk to him first before teleporting to town. Head up to the church and complete the first side job, then keep going up the hill and dig up the final worm. Teleport back into town and go to town hall, complete the second side job, and talk to Xiao. It is usually anywhere between 13:00-14:00 at this point. Teleport back into the wilds and gather whatever resources you are a. running low on or b. need for a quest/upgrade. Do this until you are out of stamina, usually by now it is anywhere between 17:00-18:00. Teleport next to my house and head down to the police station, complete the third and final side job. Hunt down Reyner and talk to him (as well as stopping to talk to everyone else I see on the way). Go to the 1st fishing spot and use up the three worms you dug up this morning to fish 3 times. If it is Wednesday or Sunday (when the church or town hall is closed) use the extra time to stop by the blacksmith's or carpenter's shop to get any upgrades you're saving up for. It is now anywhere between 2300 and 0100, go home and sleep.

Then do it all over again.

difficult to recommend budget titles for king tubby since most cd compilations and reissues are all full price. my pick of the reissues are:

king tubby's special 1973-1976 [trojan cdtrl 409]

this is the cd version of a double lp released in 1989 with excellent sleeve notes by reggae expert steve barrow and beautiful artwork. a totally fitting tribute and great music. the first lp is a straight reissue of "dubbing with the observer" with incredible versions of niney the observer productions from 1975. the second lp is bunny lee productions from 1974-76. worth every penny.

the agrovators: dub justice [attack atlp 110]

the agrovators: dub jackpot [attack atlp 111]

the agrovators: johnny in the echo chamber [attack atlp 106]

these are all compilations from 1990 on trojan's offshoot label, attack, and comprise some of the best mid 1970s b-sides from bunny lee productions on his justice and jackpot labels and his work with singer johnnie clarke. i have the vinyl versions but i think they're also out on cd with the "cdat" prefix instead of "atlp".

king tubby & friends: dub gone crazy [blood & fire bafcd 002]

a 1994 release of material from 1975-89 produced by bunny lee, again with great steve barrow sleeve notes and comprising some of the excellent versions found only on the b-sides of jamaican singles.

all these are uk-released cds at full price, so if you're in the us, i guess you'll have to pay import prices [even in the uk, they are US$21 each]. but they are all the genuine article and not cash-ins on king tubby's name, like many i have seen in the shops.

king tubby was not the only dub mixer/producer. check out errol t's work on the joe gibbs productions "african dub chapters 1-4" [out on cd, but i don't have the numbers]; keith hudson's work on the cd reissues of "brand" [pressure sounds pscd 004] and "pick a dub" [blood & fire bafcd 003]; and anything by augustus pablo [lots on cd].

happy listening!!

ROmeo -

some of the best king tubby mixes were to be found on the b-sides of many hundreds of 7-inch singles that came out of JA in the 1970s. if you see any of these in secondhand shops, grab them - even if the a-side is not so hot, the dub can be incredible. otherwise, here are some vinyl albums from the period [though not entirely king tubby mixes] that you should look out for:

dub from the roots (ja:total sounds:1974)

the roots of dub (uk:grounation grol502:1975)

shalom dub (uk:klik klp9002:1975)

king tubby meets the aggrovators at dub station (uk:live & love lalp02:1975)

king tubby meets the upsetter at the grass roots of dub (uk:fay music fmlp304/france:celluloid ltm1035/uk:studio 16 we101:1975)

harry mudie meets king tubby's in dub conference vol. 1 (ja:moodisc hm108:1975)

harry mudie meets king tubby's in dub conference vol. 2 (ja:moodisc hm110:1976)

harry mudie meets king tubby's in dub conference vol. 3 (ja:moodisc hm112:1977)

blackboard jungle dub [with lee perry/upsetters] (ja: us:clocktower:1981)

dubbing with the observer [with niney/observer all stars] (uk:attack atlp1017:1975)

king tubby's meets rockers uptown [with augustus pablo] (ja:yard music/us:clocktower:1977)

ghetto-ology dub [with sugar minnott] (ja:black roots:1981)

surrounded by the dreads at the national arena (uk:studio 16 we102)

1st, 2nd, 3rd generation of dub [with jammy/scientist] (uk:kg imperial kglp002)

dance hall style dub (us:clocktower ctlp0118)

dubbing in the backyard (uk:black music bmlp804)

majestic dub (ja:star/uk:jet star ptplp1029)

presents the roots of dub (us:clocktower ct084)

prophesy of dub (ja:prophets/uk:prophets/us:tr international tr520:1976)

the dubmaster (us:clocktower lpct0091)

upset the upsetter (uk:live & love lap15)

king tubby versus channel one studios (us:bumb bumlp101)

rocker's almighty dub (us:clocktower lpct0102)

by no means is this a complete list!! i have only listed original vinyl LPs. since then, there have been innumerable re-compilations and re-issues of King Tubby material. beware!! beware!! many of the cd's i have seen in shops that bear king tubby's name may well not be mixed by king tubby - many were simply recorded or mixed in his studio. perhaps i will post a separate list of reissues at some point.

...............................................................................

postscript - excerpt from my obituary of tubby/review of "harry mudie meets king tubby......vols 1/2/3" reissues in 1989:

"..............King Tubby's remix skills received scant attention outside the reggae world and, sadly, always remained a sideline to his electrical repair business and sound system work. Dub was the only truly innovative popular music to emerge from the 70s, and Tubby completely redefined the creative limits of what could be produced in a basic 4-track recording studio. His legacy is embodied in twelve dub LPs that are essential to any reggae collection. It's good to know that three of these are available again at long last."

City Limits magazine, 20 April 1989

Monday 30th June(cont) and Tuesday 1st July

I was organised and ready for the chauffeur and he called to confirm he would be 10 mins then a chauffeur turned up I gave my name and we loaded and left. Then I get a phone call from my emirates chauffeur asking where am I! My current chauffeur doesn’t speak English so I gave him my phone and he and my emirates chauffeur discussed the situation in Turkish. The result of which I was returned to my hotel to meet the correct chauffeur and off we went. Apparently the first chauffeur picked me up in error but The Emirates chauffeur was excellent and got me there in time. Was a bit unsettling but all ok.

Now Istanbul airport has just gone to the top of my awful airport list! It is very new and combines domestic and international. All good so far but then you walk in and what greets you is security screening! Yes before you get in to check in you do full security screening which means lifting your suitcases onto the belt to be scanned then walk through the scanner(of course I got pinged) and now you get to check in!

In their wisdom they don’t use the usual segregation by airline. You have to go to a board like the arrivals and departures board where they give you a letter and number for your flight/airline check in counter.Believe me there are a lot. You then pace around until you find it.. once that is done you need to find your gate having gone through passport control and security again! You have to walk a long way with the complete absence of any mention of gates. Eventually you hit gate signs and again not numbered , they use letters first so gates A-D then followed by 1-3 and finally another letter! So I was A3 but I should have known I am A3B . B is mentioned on my boarding card but nowhere near the gate info😏. Turns out the B means I am in the bus8ness class waiting side! Turns out that my chosen seat was changed because of any aircraft change so I negotiated from aisle on 3 spread to window on 2. The aircraft is flat bed so plenty room. I didn’t even try for the lounge! It took me over 2hrs from when I reached the airport to get to my gate. Anyway it is a Turkish Air lounge emirates can use. Apparently not too flash!

It took 45mins drive to get to the airport,over 2hrs to get to the gate and then 1 hr before boarded,then left 25 mins late. As the turnaround to the next flight is tight it should be interesting as Dubais size can really eat up your turnaround time! As it will be about 0200 hrs I won’t be the swiftest🤣. Anyway as it is an emirates flight connecting with an emirates flight I am sure it will all work out. Once I am on the Perth flight I can relax and sleep. I am occupying myself on this 4.5 hrs flight Istanbul to Dubai by eating a 3 course meal and drinking cocktail with my dinner. Not sure how the cocktail and the glass of Moët I had on boarding will mix but feel the need🤣🤣. Any way it is a very comfortable way to travel! The hot mixed nuts with my Cosmopolitan cocktail has eased the pain🤣

Good flight and on time but Murphy’s law given the tight turn around , we came in at concourse B and the Perth flight leaves from Concourse A. That means a long walk, security and passport check,lots escalators a train trip, more escalators, another carry on check and we are at the gate waiting for boarding. We got in at 0100 boarding is gazetted as 0200 and I sat down at the gate 0140. No time for the business lounge so had to queue for the general toilets!

Finally on the last leg! The flight in Business wasn’t full but it had 1st class which always seem to mean the entry into you business class seat is very narrow but once in it is fine. I got off at Perth feeling pretty good as I had a good snooze and it was 1740 arrival so not middle of the night and I had a chauffeur service to take me home and he had confirmed. Went to the carousel and grabbed my suitcase and straight through customs and found chauffeur and walked to the carousel. That’s when I realised I had collected the wrong suitcase😳. It was same coupler, brand and had same colour tag on it. So my relaxing cos I was home meant I didn’t do the same due diligence on every step as I had done all trip( unlike others I never lost or misplaced anything but pride before a fall😂). I wasn’t too stressed as I was home and I knew I would eventually get my suitcase back but I did feel guilty about the stress I had put on the other suitcase owner who would have been searching for their missing suitcase ☹️. The driver said he had never had this happen to him but he was very helpful although he said it could take hours and he wasn’t sure she could wait. He helped me flag down a very helpful Emirates man who agreed to sort it. He went off with the suitcase and my baggage claim sticker and told me to wait in front of the arrivals area and he would wave at me and hopefully give me my suitcase(he would not be permitted to exit through the arrivals area gates. The driver showed me to the seat to wait and went off to see if he could wait. He then said he could wait 15 mins and blow me down the young man waved at me after 10mins and with him was a Border Force man who did come out of the arrivals gate. He would only let me come wishing 3metres of the gate and passed my suitcase from the man tome. He also told me not to do it again🤷😏 and be more careful. Why he thought I made a practice of this beats me or that I intended to do it again I don’t know. Anyway I took it with no comment as seems best I stayed contrite😂. Then home safely! Note to self: don’t lower your due diligence and alertness practices until you are back in your house🤣🤣

Avoidability: A Look at the World Through the Lens of GL4 Multi-Valued Logic

We live in a world full of events. Some of them seem inevitable to us, like the sunrise, while others seem random, like meeting an old friend on the street. But what if we look at events that have already happened from the perspective of "Could it have been otherwise?". This idea lies at the heart of the concept of Avoidability, which finds its formal expression in a system of multi-valued logic known as GL4 (Gayane Quaternary Logic).

What is Avoidability?

Avoidability is not about predicting the future. It's a look into the past with the question: "Could this event not have happened?". It asserts that most past events had alternative paths of development. Under different circumstances, the outcome could have been different.

Imagine you decided to start learning a foreign language. This is your decision, your action. But was this decision inevitable? Could you have chosen a different hobby, dedicated your time to another activity? Most likely, yes. Your language learning is a fact, but the reasons that led you to this particular decision were not 100% predetermined. This is what Avoidability describes.

The Humanitarian and Philosophical Aspects of Avoidability:

Avoidability helps us better understand history, human behavior, and the nature of reality itself.

History: History is full of events that could have unfolded differently. Wars could have been prevented, discoveries could have been made sooner or later, political leaders could have made different decisions. Recognizing this allows us to analyze historical processes more deeply and understand that history is not a rigidly defined script, but the result of many choices and chance occurrences.

Personal Choice: Every day we make many choices. Avoidability reminds us that our decisions are not predetermined, and we are responsible for their consequences. This idea is closely related to the concept of free will.

Chance and Regularity: There is a place for both chance and regularity in the world. Avoidability helps us understand that not all events can be explained by unambiguous causes. There is an element of uncertainty that makes the world more complex and interesting. Multi-valued logic, such as GL4, allows for a more accurate description of such situations.

The Technical Aspect: GL4 and Composite Values:

GL4 is a system of multi-valued logic that goes beyond the classical binary logic of "true/false." It offers four basic states, considering both the truth/falsity of an event and its "avoidability"/"inevitability":

Inevitable True (E): The event will necessarily happen.

Avoidable True (D): The event happened, but could have not happened.

Avoidable False (C): The event did not happen, but could have happened.

Inevitable False (B): The event is impossible.

These states are called elementary values (Evag).

GL4 also uses composite values (Covag), which are combinations of elementary values. These combinations are encoded by four bits, each of which corresponds to one of the basic states. For example:

1000 corresponds to E (Inevitable True).

0100 corresponds to D (Avoidable True).

0010 corresponds to C (Avoidable False).

0001 corresponds to B (Inevitable False).

Composite values allow for the description of more complex situations where there are elements of both inevitability and avoidability, as well as truth and falsehood. For example, the value 1100 (E+D) means that the event contains both an element of inevitable truth and an element of avoidable truth.

Avoidability in GL4:

In the context of GL4, Avoidability is associated with the states "Avoidable True" (D) and "Avoidable False" (C). These states show that an event could have happened or not happened, unlike "Inevitable True" (E) and "Inevitable False" (B), where the outcome is predetermined. This is an important difference from binary logic, where an event is either true or false, without any intermediate states.

Examples in the context of GL4:

Ani is a former capital of Armenia (D - Avoidable True): Ani was the capital of Armenia, this is a historical fact (true). But history could have turned out differently, and another city could have become the capital (avoidable).

Gyumri is the capital of Armenia (C - Avoidable False): Gyumri is not the capital of Armenia (false). But in certain historical periods, there was a possibility that Gyumri could have become the capital (avoidable).

Avoidability in GL4 as part of multi-valued logic:

GL4, as a system of multi-valued logic, provides a more subtle tool for analyzing situations than classical binary logic. The concept of Avoidability allows us to consider not only the fact itself (truth or falsehood), but also how predetermined the causes leading to this fact were. This makes GL4 particularly useful for analyzing history, decision-making, and understanding complex systems where there is an element of chance and ambiguity.

Conclusion:

Avoidability is an important concept that allows us to look at the world in a new way. It reminds us that the past was not predetermined, and that we have free will that influences our present and future. GL4 multi-valued logic provides a formal apparatus for describing and analyzing this concept, making it a powerful tool for exploring complex systems and processes.

SISTEM BILANGAN DAN SISTEM KOMPUTER - Raina Haidee / 9A / 24

SISTEM BILANGAN

Sistem bilangan yang digunakan dalam komputer adalah:

Sistem Bilangan Biner

Sistem Bilangan Oktal

Sistem Bilangan Desimal

Sistem Bilangan Heksadesimal

a. Bilangan Biner

Bilangan biner atau binary digit (bit) adalah suatu sistem penulisan angka dengan menggunakan dua lambang adalah 0 dan 1.

Sistem bilangan biner modern ditemukan oleh Gottfried Wilhelm Leibniz pada masa zaman ke-17. Sistem bilangan ini merupakan landasan dari semua sistem bilangan berbasis digital.

Prinsip dari sistem bilangan biner adalah:

- Cuma punya dua simbol: nol (0) dan satu (1) - Tidak ada satu simbol yang mewakili bilangan dua - Dua adalah gabungan 1 dan 0. Sehingga angka dua bila kita tulis dalam biner menjadi 10. - Digit pada bilangan biner disebut dengan binary digit yang sering disingkat dengan bit.

b. Bilangan Oktal

Bilangan oktal adalah sebuah sistem bilangan berbasis delapan angka.

Simbol yang digunakan pada sistem bilangan ini adalah 0,1,2,3,4,5,6,7.

Bilangan biner adalah dasar semua bilangan digital yang dapat terbaca oleh sistem komputer. Walau begitu, bilangan oktal tetap diperlukan sebagai alternatif lain.

Fungsi bilangan oktal adalah memudahkan programer membuat program sebelum menerapkannya ke dalam mesin.

Bilangan oktal membantu programmer, sehingga tidak perlu menuliskan deretan bilangan biner yang rumit.

Salah satu contoh penerapan bilangan oktal dalam komputasi yakni guna mengetahui common properties pada arsip atau file HTML sebuah server.

Bilangan oktal ini awalnya diciptakan oleh Suku Yuki, yaitu salah satu suku Indian atau Amerika Asli yang bermukim di California.

Beberapa suku di Meksiko juga menghitung menggunakan jarak antar jari yang menjadi cikal bilangan oktal ini.

c. Bilangan Desimal

Sistem angka desimal hanya memiliki sepuluh (10) digit dari 0 hingga 9.

Setiap angka (nilai) mewakili dengan 0,1,2,3,4,5,6, 7,8 dan 9 dalam sistem angka ini.

Basis sistem angka desimal adalah 10, karena hanya memiliki 10 digit.

Fungsi bilangan desimal bagi sistem komputer adalah lebih memudahkan pengguna, sebab sistem bilangan desimal ini lebih mudah dikenali. Contoh sistem bilangan desimal pada komputer adalah penulisan IP Adress.

d. Bilangan Heksadesimal

Bilangan heksadesimal merupakan bilangan yang memiliki 16 basis. Simbol-simbol itu mulai dari 0 sampai 9 kemudian dilanjutkan dengan A sampai F.

Bilangan heksadesimal sering digunakan untuk memberi kode warna di dunia komputer.

Misalnya warna putih akan diberi kode warna #FFFFFF sedangkan warna warna hitam akan diberi kode warna #000000.

Format bilangan heksadesimal biasanya digunakan untuk merepresentasikan sebagian besar kode kesalahan dan nilai lain di dalam komputer.

Para programer kerap menggunakan angka heksadesimal karena nilainya lebih pendek daripada jika ditampilkan dalam format desimal dan juga jauh lebih pendek daripada dalam biner yang hanya menggunakan 0 dan 1.

Sebagai contoh, nilai heksadesimal F4240 sama dengan angka 1.000.000 dalam desimal dan 1111 0100 0010 0100 0000 dalam biner.

Jadi, nilai angka heksadesimal dapat lebih pendek jika dibandingkan angka desimal dan angka biner.

2. SISTEM KOMPUTER

Sistem Komputer merupakan sekumpulan perangkat komputer yang saling berkaitan dan berinteraksi antara satu sama lain untuk menjalankan sebuah Proses Pengolahan Data, sehingga dapat menghasilkan suatu informasi yang sangat dibutuhkan oleh penggunanya. Perangkat-perangkat yang terdapat didalam sebuah Sistem Komputer yaitu terdiri dari Hardware, Software dan Brainware.

FUNGSI SISTEM KOMPUTER

Menginput sebuah Data

Menginput Data merupakan salah satu fungsi dari sistem komputer yaitu menginput data yang sudah ada ke dalam sebuah komputer. Sistem komputer bertugas untuk menginput segala macam jenis data yang telah dimasukkan oleh seorang pengguna melalui sebuah perangkat Hardware seperti Mouse, Keyboard, Microphone dan lain sebagainya.

Memproses sebuah Data

Memproses Data merupakan salah satu fungsi dari sebuah Sistem Komputer yaitu untuk melakukan suatu Process yang bertugas untuk mentransfer sebuah data mentah menjadi suatu informasi yang bisa dibaca oleh memori komputer. Sebuah Proses data ini biasanya dilakukan pada suatu Central Processing Unit ( CPU ) yang juga memiliki fungsi sebagai otak komputer.

Menghasilkan sebuah Data

Menghasilkan Data merupakan salah satu Fungsi dari Sistem Komputer yang bertugas untuk menghasilkan sebuah Output yang merupakan salah satu hasil dari data yang sudah diproses. Hasil dari Output tersebut bisa berupa sebuah informasi, gambar, suara maupun video yang sudah sejak awal memang termasuk kedalam sebuah pengolahan data.

Menyimpan sebuah Data

Menyimpan Data merupakan salah satu fungsi dari sistem komputer yang bertugas untuk menyimpan data Output yang merupakan hasil dari olahan sebuah Process didalam memori komputer. Jadi, data yang sudah diinput dan diproses akan menjadi sebuah Output Data yang bisa kita simpan di dalam sebuah memori komputer yang nantinya bisa digunakan dalam waktu tertentu.

KOMPONEN SISTEM KOMPUTER

A. KOMPONEN HARDWARE

Hardware atau biasa kita sebut sebagai Perangkat Keras yaitu merupakan perangkat yang mempunyai wujud fisik dan bisa disentuh. Perangkat ini terdiri dari berbagai macam benda komputer yang biasa kita pakai. Contohnya seperti Monitor, Mouse, Keyboard, dan CPU, semua komponen tersebut merupakan bagian dari komponen Hardware Komputer.

Central Processing Unit (CPU)

CPU atau Central Processing Unit merupakan otak dari sebuah sistem komputer. Unit ini memiliki tanggung jawab dari semua kegiatan yang telah terjadi dan sudah di Proses didalam sebuah Komputer. CPU memiliki fungsi sebagai pusat Pengelolahan Data dan mengontrol segala macam perangkat Internal maupun Eksternal yang terhubung pada sebuah Komputer.

Input Unit (Input Device)

Input Device merupakan salah satu perangkat keras komputer yang bertugas sebagai alat yang berguna untuk memasukan data atau sebuah perintah ke dalam Komputer.

Contohnya :

Keyboard

Pointing Device

Mouse

Touch screen

Digitizer Grapich Tablet

Scanner

Microphone

Output Unit (Perangkat Keluaran)

Output unit mempunyai fungsi yang bertolak belakang dengan Input unit. Jika pada sebuah input unit data yang diperoleh dari luar dimasukkan ke dalam sistem komputer, maka output unit sebaliknya. Output Unit menghasilkan suatu informasi atau sebuah data yang merupakan hasil dari pemrosesan pada sistem komputer. Data yang dihasilkan dapat berupa sebuah infromasi, gambar, suara atau video.

Storage Unit (Perangkat Penyimpanan)

Perintah yang telah dimasukkan pada suatu Sistem Komputer melalui sebuah Input Unit kemudian akan disimpan di Unit Storage sebelum benar-benar melalui sebuah Pemrosesan. Begitupun dengan hasil dari sebuah data yang sudah selesai diproses, data tersebut akan terlebih dahulu disimpan pada sebuah Storage Unit sebelum dipindahkan ke Output Unit. Storage Unit dibagi menjadi dua jenis yaitu, sebagai berikut ini :

Internal Storage Unit

External Storage Unit

B. KOMPONEN SOFTWARE

Software merupakan sekumpulan data Elektronik yang disimpan dan diatur oleh sebuah komputer. Data tersebut yang sudah disimpan oleh sebuah Komputer dapat berupa suatu Program atau Instruksi yang akan melaksanakan suatu perintah. Melalui sebuah software atau perangkat lunak inilah Komputer dapat menjalankan suatu perintah yang di berikan.

Operating System (Sistem Operasi)

Sistem Operasi komputer merupakan sebuah program dasar yang ada pada komputer, umumnya berfungsi untuk menghubungkan seorang pengguna dengan Hardware. Bisa dikatakan juga bahwa Sistem Operasi merupakan Perangkat Lunak yang berfungsi untuk melakukan suatu pengontrolan dan memanagemen perangkat keras serta termasuk menjalankan sebuah aplikasi yang dapat melakukan suatu proses pengolahan data.

Contohnya : Microsoft Windows, Linux, Mac OS, dan lain sebagainya.

Program Aplikasi (Aplication Program)

Program Aplikasi merupakan salah satu kategori software yang digunakan untuk membantu sebuah pekerjaan seorang pengguna Komputer untuk bisa mengolah berbagai macam Data Komputer. Perangkat Lunak Komputer pada umumnya hanya diinstal sesuai dengan kebutuhan dari seorang pengguna komputer tersebut.

Contohnya :

Microsoft Excel

Microsoft Word

Microsoft Access

Photo Shop

Web browser

Game dan masih banyak yang lain

Utility Software (Program Tambahan )

Utility Software merupakan salah satu kategori software yang bertugas menjaga dan melindungi suatu sistem komputer tetapi tidak berhadapan lansung dengan sebuah Hardware.

Contohnya : Software Anti Virus, Firewall, Disk Defragmenter, Screensever dan lain sebagainya.

Programing Language (Bahasa Pemerograman)

Programing Language merupakan salah satu bahasa yang biasa digunakan oleh seorang Pengguna Komputer untuk mempermudah sebuah komunikasi dengan komputer. Programing Language bisa dikatakan juga sebagai sebuah Standar Bahasa yang merupakan suatu instruksi untuk berkomunikasi dan memberikan suatu perintah pada komputer tersebut.

Contohnya : PHP, Java, Python, C, Perl dan lain sebagainya.

C. KOMPONEN BRAINWARE

Brainware yaitu merupakan orang yang melaksanakan atau mengoperasikan sebuah komputer. Brainware mempunyai peran yang sangat penting karena sebuah komputer tidak dapat digunakan jika tidak dioperasikan oleh Manusia. Jadi brainware yaitu merupakan orang yang terlibat dalam suatu kegiatan pemanfaatan sebuah Komputer. Pengguna komputer dibagi menjadi empat jenis yaitu, diantaranya sebagai berikut :

Programer

Programmer yaitu seseorang yang memiliki keahlian untuk menguasai banyak atau salah satu dari suatu bahasa pemerograman. Jadi seorang programer bisa dikatakan sebagai orang yang membuat dan memiliki sebuah tugas untuk mempersiapkan suatu program yang memang dibutuhkan dalam sistem komputer yang akan dipakai untuk mengolah sebuah data.

Contohnya : PHP, Java, Phyton, C dan lain sebagainya.

Sistem Analis

Sistem Analis merupakan orang yang bertanggungjawab terhadap sebuah penelitian, perencanaan, penkoordinasian dan merekomendasikan pilihan dari suatu software, hardware dan sistem yang sesuai dengan kebutuhan dari seorang penggunanya. Seseorang yang bertugas sebagai Sistem Analis pun sangat berperan dalam sebuah proses pengembangan dari suatu sistem.
