Study Notes
Hardware Components
- A network card provides a computer with a network connection, either through wireless signals or a physical cable connection.
- An optical disk drive (CD/DVD/Blu-Ray) allows optical disks to run on a computer and can also write data onto discs.
- A power supply connects to main power sources and provides power to the computer system, including the motherboard, hard drive, and optical drives.
Internal Hardware Devices
- Examples of internal hardware devices include processor, motherboard, random access memory (RAM), read-only memory (ROM), video cards, sound cards, and internal hard disk drives.
External Hardware Devices
- Examples of external hardware devices include monitors, keyboards, mice, printers, and external storage devices.
- Input devices allow users to input data into a computer, such as a mouse, keyboard, and microphone.
- Output devices display data from a computer, such as a monitor and speakers.
- External storage devices provide external storage or backup solutions, such as an external hard drive.
Computer Software
- Software is a collection of instructions that can be run on a computer, telling the computer what to do.
- Software is not a physical thing, but it can be stored on a physical medium such as a CD-ROM.
- A computer system needs both hardware and software to be useful.
Application Software
- Examples of application software include word processing, spreadsheet, database management systems, and photo-editing software.
- Application software is designed to allow users to complete specific tasks, such as writing a letter, browsing the internet, or manipulating data in a spreadsheet.
- Examples of application software include:
- Word processing software, used to prepare reports, school essays, etc.
- Spreadsheet software, used to create and organise numeric data.
- Database software, used to insert and organise data using fields and records.
- Photo-editing software, used to edit digital images.
- Graphics manipulation software, used to create and edit bitmap and vector graphics.
- Video-editing software, used to edit and format video using various tools and techniques.
- Apps (phone applications), used to run on mobile phones.
- Measuring and control software, responsible for changing physical conditions in an environment.
System Software
- Examples of system software include operating systems, device drivers, and utilities.
- System software is normally involved in the running of the computer, providing a user interface, allowing hardware components to work, and maintaining computer performance.
- Examples of system software include:
- Operating systems, which manage a computer's functions, including hardware devices.
- Device drivers, which allow hardware devices to run on the computer.
- Utilities, which maintain the computer's performance, such as antivirus software.
