What is ascii ? • ASCII pronounced as "ask-key" stands for the American Standard Code for Information Interchange and was proposed by ASA (American Standard Association) in 963 and was finalised in 1968.ASCII is a standard of 8-bit code used to represent characters, which include letters, numbers and punctuation marks. 8 bits allow the computer to encode a total of 128 characters for the numbers 0-9, uppercase and lowercase letters A-Z and a few punctuation symbols. However this 128 bit code only suitable for english language speaking users. • ASCII yang dilafazkansebagai "meminta-utama" berdiriuntukKod American Standard untukPersimpanganMaklumatdantelahdicadangkanoleh ASA (American Standard Association) 963 dantelahdimuktamadkandalam 1968.ASCII standard kod 8-bit digunakanuntukmewakiliaksara, yang termasukhuruf, nombordantandabacaan. 8 bit membolehkankomputeruntukmengekodsejumlah 128 aksarauntuknombor 0-9, hurufbesardanhurufkecil AZ dansimboltandabacabeberapa.

FUNCTION OF ASCII ASCII enables manufacturers to produce components that are assured to operate correctly in a computer . ASCII membolehkanpengeluaruntukmenghasilkankomponen yang memberijaminanuntukberoperasidenganbetuldalamkomputer. • ASCII was established to achieve compatibility between various types of data processing equipment making it possible for the component to communicate with each other successfully. • ASCII telahditubuhkanuntukmencapaikeserasianantarapelbagaijenisperalatanpemprosesan data menjadikaniamungkinbagikomponenuntukberkomunikasiantarasatusama lain berjaya. ASCII / American Standard Code for Information Interchange ASCII makes it possible for humans to interact with a computer. It also enables users to purchase components that are compatible with their computer configurations.

HOW ASCII WORKS IN A COMPUTER ?SYSTEM ? • 1.Number 9 is typed using the keyboard • 2.Electronic signal in sent to CPU for the computer to process. • 3.Number 9 is converted to 00111001 • 4.Computer finishes processing the byte. • 5.The software converts the byte back to the number 9 • 6.Number 9 is displayed on the monitor screen 1.Nombor 9 ditaip menggunakan keyboard2. Isyarat elektronik dalam dihantar ke CPU untuk komputer untuk proses.3. Nombor 9 ditukar kepada 001110014. Komputer selesai memproses bait.5. Perisian ini menukarkan kembali bait bilangan 96. Bilangan 9 dipaparkan pada skrin monitor
Example : • A computer cannot store letters as you see them on the screen. Remember it is only a binary system.So, it has to have some way to represent the character internally as a numeric. The ASCII code set is the way that is done.The extended set are additional symbols that came out, in the late 80's that represent non-standard characters. These were used by DOS (Disk Operating System) applications to piece together borders and tables. They also contain symbols used for other languages.

State the unit of data MEasurement : Why Is 1024 bytes = 1KB 2⁰ = 1 2¹ = 2 2² = 4 2³ = 8 2⁴ = 16 2⁵ = 32 2⁶ = 64 2⁷ =128 2⁸ = 256 2⁹ =512 2¹⁰=1024
question • In mathematics,1KB equal to 1000 bytes.In computer,1KB equal to 1024 bytes.How many bytes equal to megabytes? Dalamkiraan matematik,1KB bersamaandengan 1000 bait.Dalamkiraankomputer 1Kb bersamaan 1024bait.Berapa bait yang bersamaandengan 1 megabait. A.1 048 476 bait. B.1 048 576 bait. C.1 048 676 bait. D.1 048 776 bait.
(Nyatakansamaadapernyataanberikutbenarataupalsu) 2. A bytes is a binary digit,the smallest increment of data on a computer.A byte can hold only one of two values:0 or 1,corresponding to the electrical values of or on respectively.
