Introduction to computer :)

WHAT IS COMPUTER ?

An electronic device that accept data (input), process input to useful information (process), according to a set of instructions, store the instructions and the results of processing (storage), and produce the information (output).

2 IMPORTANT ELEMENTS :

  • Hardware

  • Software

ARCHITECTURE & ORGANISATION

What is architecture ?
  • those attributes visible to the programmer
  • Instruction set, number of bits used for data representation, I/O mechanisms, addressing techniques.
What is organisation ?
  • how features are implemented
  • Control signals, interfaces, memory technology.
STRUCTURE & FUNCTION

structure :

  • the way in which components relate to each other.
  • top-level :

From the Top-Level Structure, a computer consists of four main structural components, which are:
  1. Central processing unit (CPU) – referred as processor, perform data processing and control the operation of the computer
  2. Main memory – stores data
  3. I/O – move data between the computer and its external environment
  4. System interconnection - provides communication among CPU, maim memory and I/O
  • the CPU

CPU itself consists of several components such as:

  1. registers – provides storage internal to the CPU
  2. arithmetic and logic unit (ALU) – perform data processing function
  3. control unit – control the operation of CPU
  4. internal CPU interconnection – provides communication among ALU, registers and control unit

function :

  • the operation of individual components as part of the structure.
  • four basic functions performed by a computer system :
--> data processing
--> data storage (long term data storage function and short term data storage function)
--> data movement (movement between computer and peripheral known as input / output (I/O), movement over longer distances known as data communication)
--> control

CLASSES OF COMPUTERS :

  • Desktop computer


  • Server computer


  • Embedded computer



COMPUTER TYPES :


~ microcomputer ~


~ workstation ~


~ mainframe ~


~ supercomputer ~

where it begin...

Assalamualaikum n hello dear friends ! :D

We were assigned an assignment by our lecturer, En. Fairuz to make a blog about our subject which is Computer Organisation & Architecture (C.O.A). So here it is where are you reading on :)

Since this is our first time making a blog, we do hope you will gain something from our post and ignore it if we might lacking on something or you can leave a comment whether to motivate us or tell us to improve our post oritee :)


okayy. there are 5 members in our group which is :



  1. Siti Na'ilah bt yusop
  2. Siti Faidzah bt Abdul Razak
  3. Nohazuani bt Mohd Ghani
  4. Nur Syafiqah Amnani bt Adnan
  5. Wan Nur Najihah bt Wan Jusoh

Each member will have to post a different subtopic that we have learned in lectures and laboratory sessions.
Do enjoy our blog !
