Content

Definitions and Explanations

1. Define Computer Processing Computer processing is the act of using a computer’s CPU to carry out instructions and perform tasks. This includes calculations, data manipulation, and managing the flow of information within the computer system.
2. Types of Computers Based on Processing Speed or Capacity
   • Supercomputers: Extremely fast and powerful, used for complex computations like weather forecasting.
   • Mainframe Computers: Large and powerful, used by large organizations for bulk data processing.
   • Minicomputers: Mid-sized, used in manufacturing processes and scientific research.
   • Microcomputers: Commonly known as personal computers (PCs), used for everyday tasks by individuals and businesses.
3. What Are Computer Peripherals? Computer peripherals are external devices that connect to a computer to add functionality. Examples include:
   • Input devices (keyboard, mouse)
   • Output devices (monitor, printer)
   • Storage devices (external hard drives, USB drives)
4. Methods of Computer Processing
   • Batch Processing: Collecting and processing data in large groups or batches at a scheduled time.
   • Real-time Processing: Processing data instantly as it is inputted, used in applications like online transactions.
   • Distributed Processing: Using multiple computers or processors to work on different parts of a task simultaneously.
