Study Notes
What is a Computer?
- A computer is an electronic device that can store, process, and communicate information.
Importance of Information
- Information is the purpose of a computer system, as it enables storage, processing, and communication of data.
Unique Characteristics of Computers
- A computer differs from other devices in its ability to process and store information.
IT and Information Systems
- IT stands for Information Technology, which involves the development, implementation, and management of computer-based information systems.
- An Information System (IS) manages the flow of information within an organization to support decision-making, operations, and management.
Examples of Information Systems
- A university's student registration system is an example of an Information System (IS).
Components of an Information System
- The memory unit stores data and programs in a computer.
Input/Output Devices
- Input devices, such as keyboards and scanners, allow people to supply information to computers.
CPU Functions
- The Arithmetic Logic Unit (ALU) performs arithmetic and logical operations in the CPU.
Secondary Memory Storage
- Examples of secondary memory storage include hard disks, solid-state drives (SSDs), and flash drives.
Documentation
- The rules or guidelines for using software, hardware, and data are documented in user manuals or online support resources.
