Study Notes
Information Processing Cycle
- A computer stores data in memory locations called memory.
- The Central Processing Unit (CPU) processes the data.
- The processed results are called output, which is conveyed to the user.
- Data entered into a computer is called input.
- The cycle of input, process, output, and storage is called the Information Processing Cycle.
Functions of ICT
- ICT acts as a tool and medium for teaching and learning in education.
- ICT offers new opportunities in business, such as e-commerce, online and mobile transactions.
- ICT provides access to and dissemination of ICT resources.
- ICT enables organizations to automate processes, such as Personal Computers (PCs).
- ICT has become an integral and accepted part of everyday life.
Classification of Computers
- Computers differ based on their data processing abilities.
- Classification according to purpose:
- General purpose computers perform a range of tasks.
History of Computers
- First Generation (1940-1956): Vacuum Tubes and magnetic Drums
- Characteristics: expensive to operate, consumed a lot of electricity, generated heat, and used machine language.
- Examples: Universal Automatic Computer (UNIVAC) and Electronic Numerical Integrator and Computer (ENIAC).
- Second Generation (1956-1963): Transistors
Components of a Computer System
- Hardware: physical components of the computer.
- Software: programs that control the operations of the computer and its devices.
System Software
- Types: Operating systems, Utility programs, and Translators.
- Functions:
- Starting up the computer.
- Opening, executing, and running applications.
- Storing, retrieving, and copying files.
- Formatting disks.
- Reducing file sizes.
- Backing up the contents of a hard disk.
