Study Notes
Hardware Categories
- Input devices are used to enter data, commands, and programs into the computer.
- Examples of input devices include: keyboard, mouse, trackball, joystick, light pen, scanners, and digital cameras.
- Output devices include: monitor or display, printer, and speakers.
Software Categories
- Computer software consists of routines, programs, procedures, and specialized aids that make hardware components perform their functions.
- Operating system (OS) is the basic software responsible for interacting with the hardware and is the foundation for user programs and application programs.
- Application programs are used for carrying out specific tasks, such as office document creation, pay roll processing, and publishing.
- Utility programs are a type of software.
Data Ware
- Data ware refers to the systematic and organized collection of data and procedures relevant to an organization.
People Ware
- People ware refers to personnel who manage and use the computer system, design applications and systems software, write and encode programs, and run the hardware.
Computer Basic Operations
- Input refers to whatever goes into the computer, including commands, data from another computer, or device.
- Input devices feed data into a computer, such as a keyboard or mouse.
- Output is any information (data) that comes out of a computer, including output devices such as display screens, speakers, and printers.
Storage
- Computer data storage is referred to as storage or memory, which can save digital data.
- Examples of storage devices include RAM, hard disks, CDs, DVDs, and removable flash memory sticks.
- Permanent, or non-volatile, storage devices do not require power to remember the data stored.
- Mass storage devices, like hard disk, are non-volatile, and a loss of power does not affect their ability to retain data.
- ROM (Read Only Memory) is a type of non-volatile storage.
- Temporary or volatile storage is more often called "memory".
- A loss of power means that any data stored in volatile storage will be lost irretrievably.
Processing
- The processor is the brain of a computer and is also called the CPU (Central Processing Unit).
- The processor is a microchip that performs simple operations like basic arithmetic and comparing two values.
- The processor actually performs the operations directed by a program.
