Study Notes
Computer Hardware and Components
- The output device is responsible for sending information back to the user on a PC.
Computer Memory
- PC memory is measured in terms of capacity, typically in bytes (e.g., kilobytes, megabytes, gigabytes).
Computer Generations
- A major development in 4th generation computers was the introduction of microprocessors.
Networking
- The purpose of a LAN (Local Area Network) is to connect computers and devices in a limited geographical area for communication and resource sharing.
Computer Performance
- The factor that significantly impacts a computer's performance is the capacity of its components, including the processor, memory, and storage.
Computer System Components
- The three main components of a computer system are the input device, processing unit, and output device.
Computer Terminology
- The term "hardware" is used to refer to the equipment associated with a computer system.
Computer History
- The 1st generation of computers used vacuum tubes for circuitry and magnetic drums for memory.
- In the 2nd generation of computers, vacuum tubes were replaced with transistors.
- The 2nd generation of computers used high-level programming languages, such as assembly languages and COBOL.
