What to Focus On

  • A computer system includes CPU, memory, input/output devices, and storage devices.
  • CPU is the brain of the computer and carries out actual processing.
  • Registers are small, fast storage locations inside the CPU chip.
  • Input devices convert data into digital form.
  • Output devices convert digital information into human-understandable form.
  • Braille input and output devices support visually impaired users.
  • Von Neumann architecture includes CPU, memory, input/output devices, and communication channels.
  • ENIAC is the first binary programmable computer based on Von Neumann architecture.
  • Moore's Law predicted transistor count doubling every two years.

Common Mistakes to Avoid

CPU and microprocessor mean exactly the same thing in every context.

RAM stores data permanently, just like a hard disk or other storage device.

ROM is used for temporary working data, while RAM stores the boot program.

Memory Tips
