2.1.1 Overview of Computer Systems2.1.1.2 State the meaning of input, processor, output and storage.I.INPUTINPUT IS ANY DATA OR INSTRUCTIONS THAT WE ENTER INTO THE COMPUTER SYSTEM FOR PROCESSING.

II.PROCESSPROCESS IS A MACHINE CYCLE THAT CONSIST FOUR BASIC OPERATIONS, THATS ARE FETCHING,ECODING, EXECUTING AND STORING.

III.OUTPUTOUTPUT IS DATA THAT HAS BEEN PROCESSED INTO A USEFUL FORM, CALLED INFORMATION. THERE ARE FOUR TYPES OF OUTPUT, WHICH ARE TEXTS, GRAPHICS, AUDIO AND VIDEO.

IV.STORAGESTORAGE IS A LOCATION WHICH DATA, INSTRUCTION AND INFORMATION ARE HELD FOR FUTURE USE. EVERY COMPUTER USES STORAGE TO HOLD SYSTEM SOFTWARE AND APPLICATION SOFTWARE

2.1.1 Overview of Computer Systems2.1.1.2 State the meaning of input, processor, output and storage.I.MASUKANMASUKAN ADALAH APA-APA DATA ATAU ARAHAN YANG DIMASUKKAN KE DALAM SISTEM KOMPUTER UNTUK DIPROSES

II.PROSESPROSES ADALAH KITARAN MESIN YANG MENGANDUNGI 4 OPERSI IAITU MENARIK, MENGKOD, MELAKSANA DAN MENYIMPAN.

III.KELUARANKELUARAN ADALAH DATA YANG DIPROSES KE DALAM BENTUK BERGUNA DIPANGGIL MAKLUMAT. ADA 4 JENIS KELUARAN IAITU TEKS, GRAFIK,AUDIO DAN VIDEO.

IV.SIMPANANSIMPANAN ADALAH TEMPAT DI MANA DATA, ARAHAN DAN MAKLUMAT DISIMPAN UNTUK KEGUNAAN AKAN DATANG. SETIAP KOMPUTER MEMPUNYAI SIMPANAN UNTUK MEMEGANG PERISIAN SISTEM DAN PERISIAN APLIKASI.

2.1.1 Overview of Computer Systems2.1.1.3 Describe the information processing cycle which includes input, process, output and storage.USER WILL INPUT THE DATA TO BE PROCESSED BY THE PROCESSOR. THESTORAGE HOLDS DATABASES, FILES AND PROGRAMS. THE OUTPUT DEVICESPRESENT THE PROCESSED DATA AS USEFUL INFORMATION PRODUCTS FOR THEUSERPENGGUNA AKAN MEMASUKKAN DATA UNTUK DIPROSES OLEH PEMPROSESAN.SIMPANAN AKAN MEMEGANG PANGKALAN DATA, FAIL DAN PROGRAM. PERANTIKELUARAN MEMPERSEMBAHKAN DATA YANG TELAH DIPROSES KE DALAM BENTUK MAKLUMAT YANG BERGUNA UNTUK PENGGUNA

2.1.2 DATA REPRESENTATION2.1.2.1State the relationship of data representation : bit, byte and character.BITA BIT IS THE SMALLEST UNIT OF DATA THAT THE COMPUTER CAN PROCESS. BIT IS A SHORT FOR BINARY DIGIT. A BIT IS REPRESENTED BY THE NUMBERS 1 AND 0. MERUPAKAN UNIT DATA TERKECIL DI MANA PC BOLEH MEMPROSESNYA. BIT SANGAT PENDEK UNTUK DIGIT BINARI. IA MEWAKILI NOMBOR 0 DAN 1

BYTEBYTE IS A UNIT OF INFORMATION BUILT FROM BITS. ONE BYTE IS EQUALS TO 8 BITS. BAIT ADALAH UNIT MAKLUMAT DARIPADA BIT. SATU BAIT BERSAMAAN 8 BIT.

CHARACTER8 BITS = 1 BYTE8 BIT = 1 BAIT

MAKA GIGAHERTZ BERSAMAAN DENGAN KITARAN SATU RIBU JUTA DARIPADA SISTEM JAM 1 GHZ = 1,000,000,000 CYCLES 1 SECOND 1 GHZ = 1000 MHZ

Topic 2.2 - PERKAKASAN (HARDWARE)

2.2.1 Input Devices2.2.1.1 Identify the input devices used for text, graphic, audio and videoText keyboardGraphic scannerAudio microphoneVideo webcam

2.2.2 Output Devices 2.2.2.1 Identify the output devices used fortext, graphic, audio and video

2.2.3 Motherboard2.2.3.1 Identify the location of the central processing unit (CPU), expansion slots, expansion cards, RAM motherboard

2.2.4 Storage2.2.4.1 Explain types and function of : - primary stroge (RAM , ROM )PRIMARY STORAGE IS KNOWN AS THE MAIN MEMORY OF A COMPUTER, INCLUDING RAM (RANDOM-ACCESS MEMORY) AND ROM (READ-ONLY MEMORY) IT IS AN INTERNAL MEMORY (INSIDE THE CPU) THAT CAN BE ACCESSED DIRECTLY BY THE PROCESSOR.

FUNCTION OF RAM :RAM IS VOLATILE WHICH MEANS THE PROGRAMS AND DATA IN RAM ARE LOST WHEN THE COMPUTER IS POWERED OFF.A COMPUTER USES RAM TO HOLD TEMPORARY INSTRUCTIONS AND DATA NEEDED TO COMPLETE TASKS. THIS ENABLES THE COMPUTER'S CPU (CENTRAL PROCESSING UNIT) TO ACCESS INSTRUCTIONS AND DATA STORED IN THE MEMORY VERY QUICKLY.RAM STORES DATA DURING AND AFTER PROCESSING.

FUNCTION OF ROM :ROM IS NON-VOLATILE. IT HOLDS THE PROGRAMS AND DATA WHEN THE COMPUTER IS POWERED OFF.PROGRAMS IN ROM HAVE BEEN PRE-RECORDED. IT CAN ONLY BE STORED BY THE MANUFACTURER; ONCE IT IS DONE, IT CANNOT BE CHANGED.MANY COMPLEX FUNCTIONS, SUCH AS START UP OPERATING INSTRUCTIONS, TRANSLATORS FOR HIGH-LEVEL LANGUAGES AND OPERATING SYSTEMS ARE PLACED IN ROM MEMORY.

2.2.4 Storage2.2.4.1 Explain types and function of : - primary stroge (RAM , ROMSTORAN /SIMPANAN PRIMER(UTAMA) DIKENALI SEBAGAI MEMORI UTAMA PC, IA TERMASUK RAM (MEMORI CAPAIAN RAWAK) DAN ROM (MEMORI CAPAIAN BACA SHJ)IA MERUPAKAN MEMORI DALAMAN (DI CPU/UNIT PEMPROSESAN PUSAT) YANG BOLEH DICAPAI TERUS OLEH PEMPROSES.

FUNGSI RAMRAM ADALAH MERUAP DI MANA PROGRAM DAN DATA DI DALAM RAM AKAN HILANG APABILA PC DITUTUP.PC MENGGUNAKAN RAM UNTUK MEMEGANG SEMENTARA ARAHAN DAN DATA UNTUK MENYIAPKAN TUGASAN. INI MEMBOLEHKAN CPU KOMPUTER UNTUK MENCAPAI ARAHAN DAN DATA YANG TERSIMPAN DI DALAM MEMORI DENGAN CEPATRAM MENYIMPAN DATA SEMASA DAN SELEPAS BERLAKUNYA PROSES.

FUNGSI ROMROM TIDAK MERUAP DI MANA MAKSUDNYA IA MEMEGANG DATA DAN PROGRAM WALAUPUN KOMPUTER DITUTUP DAN DIBUKA SEMULAPROGRAM DI DALAM ROM ADA PRA REKOD. IA HANAYA BOLEH DISIMPAN OLEH PEMBINA PROGRAM. APABILA IA DIBUAT MAKA IA TIDAK BOLEH DIUBAHBANYAK FUNGSI RUMIT SEPERTI MEMBUKA ARAHAN OPERASI, ALAT PENUKARAN BAHASA ARAS TINGGI DAN SISTEM OPERASI ADALAH TERLETAK DI DALAM ROM.

2.2.4 Storage2.2.4.2 Explain types and function of : - secondary stroge (Magnetic and optical medium AND Flash memory )SECONDARY STORAGE IS ANOTHER ALTERNATIVE STORAGE TO KEEP YOUR WORK ANDDOCUMENTS. IT IS VERY USEFUL TO STORE PROGRAMS AND DATA FOR FUTURE USE.SIMPANAN KEDUA ADALAH SATU LAGI SIMPANAN ALTERNATIF YANG MENYIMPAN KERJADAN DOKUMEN. SANGAT BERGUNA UNTUK MENYIMPAN PROGRAM BAGI MASA DEPAN 1. MAGNETIC MEDIUM / MEDIUM MAGNETIKIS A NON-VOLATILE STORAGE MEDIUM. IT CAN BE ANY TYPE OF STORAGE MEDIUM THATUTILIZES MAGNETIC PATTERNS TO REPRESENT INFORMATION. THE DEVICES USE DISKSTHAT ARE COATED WITH MAGNETICALLY SENSITIVE MATERIAL. THE EXAMPLES OF MAGNETIC STORAGE ARE:MAGNETIC DISK SUCH AS:A FLOPPY DISK, USED FOR OFF-LINE STORAGEHARD DISK, USED FOR SECONDARY STORAGEMAGNETIC TAPE; INCLUDING VIDEO CASSETTE, AUDIO STORAGE REEL-TO- OPTICAL MEDIUM IS A NON-VOLATILE STORAGE MEDIA THAT HOLDS CONTENT IN DIGITAL FORM THAT ARE WRITTEN AND READ BY A LASER. THESE MEDIA INCLUDE VARIOUS TYPES OF CDS AND DVDS. MERUPAKAN SIMPANAN TIDAK MERUAP. IA BOLEH JADI PELBAGAI JENIS BERBENTUK MAGNETIK UNTUK MEMPERSEMBAHAKAN MAKLUMAT. PERANTI MENGGUNAKAN CAKERA YANG DISALUT BAHAN SENSITIF BERMAGNETCONTOH SIMPANAN MAGNETIK ADALAHCAKERA MAGNETIK SEPERTI (DISKET/CAKERA KERAASTAPE MAGNETIK TERMASUKLAH VIDEO KASET DAN SEBAGAINYA.

2.2.4 Storage2.2.4.2 Explain types and function of : - secondary stroge (Magnetic and optical medium AND Flash memory )

2. OPTICAL MEDIUM / MEDIUM OPTIKTHESE FOLLOWING FORMS ARE OFTEN COMMONLY USED :CD, CD-ROM, AND DVD: READ ONLY STORAGE, USED FORDISTRIBUTION OF DIGITAL INFORMATION SUCH AS MUSIC,VIDEO AND COMPUTER PROGRAMS.CD-R: WRITE ONCE STORAGE, THE DATA CANNOT BE ERASED OR WRITTEN OVER ONCE IT IS SAVED.CD-RW, DVD-RW, AND DVD-RAM: SLOW TO WRITE BUT FAST READING STORAGE; IT ALLOWS DATA THAT HAVE BEEN SAVED TO BE ERASED AND REWRITTEN.REEL TAPE AND OTHERS.BEBERAPA PENDEKATAN SERING DIGUNAKAN SEPERTI: CD: SIMPANAN BACA SAHAJA DIGUNAKAN UNTUK MEMPERSEMBAHKAN MAKLUMAT DIGITAL SEPERTI MUZIK, VIDEO DAN PROGRAM KOMPUTERCD-R: SIMPANAN TULIS SAHAJA. DATA TIDAK BOLEH DIPADAM ATAU DITULIS SEMULACD-RW, DVD- RW DAN DVD-RAM: LAMBAT DITULIS TETAPI CEPAT DIBACA SEMULA. IA MEMBENARKAN DATA DISIMPAN, DIPADAM DAN DITULIS SEMULATAPE GELENDONG DAN SEBAGAINYADVD=Digital Versatile Disc

2.2.4 Storage2.2.4.2 Explain types and function of : - secondary stroge (Magnetic and optical medium AND Flash memory )3. FLASH MEMORYFLASH MEMORY IS A SOLID-STATE, NON-VOLATILE, REWRITABLE MEMORY THAT FUNCTIONS LIKE RAM AND A HARD DISK DRIVE COMBINED. FLASH MEMORY STORE BITS OF ELECTRONIC DATA IN MEMORY CELLS JUST LIKE DRAM (DYNAMIC RAM), BUT IT ALSO WORKS LIKE A HARD DISK DRIVE THAT WHEN THE POWER IS TURNED OFF, THE DATA REMAINS IN THE MEMORY. FLASH MEMORY CARDS AND FLASH MEMORY STICKS ARE EXAMPLES OF FLASH MEMORY

MEMORI FLASH SANGAT JELAS, TIDAK MERUAP, MEMORY BOLH BACA,TULIS DAN TULIS SEMULA YANG BERFUNGSI SEPERTI RAM DAN CAKERA KERAS. MEMEORI FLASH MENYIMPAN BITS DARIPADA DATA ELEKTRONIL DI DALAM SEL MEMORI SAMA SEPERTI DRAM(DYNAMIC RAM). MALAH IA JUGA BEKERJA SEPERTI CAKERA KERAS DI MANA WALAUPUN PC DITUTUP DAN DIBUKA SEMULA, DATA KEKAL DALAM MEMORI. KAD MEMORI FLASH DAN KAYU MEMORI FLASH ADALAH CONTOH-CONTOH MEMORI FLASH.
