  • Input devices send data to the CPU.
  • Output devices display data processed by the CPU.
  • Storage holds data and instructions.

Von Neumann Architecture

  • The Von Neumann architecture describes a computer's components and their connections.
  • The CPU, memory, and input/output (I/O) components interact through buses.
  • Data bus, address bus, and control bus transmit data.
  • The CPU (Central Processing Unit) is connected directly to memory through these buses.

Bus

  • A bus is an electrical pathway for data transfer between components.
  • Local bus connects the CPU to memory.
  • Expansion bus connects the CPU to peripherals.

  • These components dissipate excess heat.

Parallel Processing

  • Parallel processing utilizes multiple processors.
  • It significantly speeds up tasks.
  • Efficiently dividing up tasks to different processors is a critical factor.

Data Representation

  • Computers represent data digitally, using binary system.
  • A single bit is either 0 or 1.
  • A byte consists of 8 bits.

Byte

  • A byte is a grouping of 8 bits.
  • It can represent 256 different values.
  • It's used to store characters, numbers, punctuation, etc.
  • Data is represented by particular combinations of bits.

Coding Systems

  • ASCII, EBCDIC, and Unicode are common coding systems

Letter to Binary Conversion

  • Inputting a letter triggers a binary code in memory.
  • This binary code represents the input character.
  • Then, the binary code is displayed on the computer screen in the corresponding character format.
