Computer Terms Study Guide
Hardware and software are two basic parts of a computer system.
Hardware is the physical devices of a computer system or any part of a computer system you can touch.
Software is a set of instructions that tell a computer what to do.
A peripheral is any piece of hardware attached to a computer, such as a printer.
Hardware and software should come with information that tells you how to set up and use the product. This is called documentation.
A computer inputs, processes, stores, and outputs information.
An input device lets you communicate with a computer.
A keyboard is an input device that provides a means of entering data into the computer.
Other examples of input devices are: mouse, scanner, microphone, and joystick.
The Central Processing Unit or CPU for short, is the main chip in a computer. It is considered the brain of the computer.
A storage device holds information. Examples of storage devices are: hard drive , floppy drive and flash memory stick .
The hard drive is found inside the CPU and is used to store information.
A floppy drive stores and retrieves information on floppy disks.
An output device lets a computer communicate with you. Examples of these devices are: monitor, printer, and speakers.
A computer has two kinds of memory: RAM and ROM.
RAM stands for random access memory . This memory is temporary, which means that if you turn off your computer, information here will be lost.
ROM stands for read only memory. This memory is permanent memory, which means that information stored here will stay there even when you turn off the computer.
The amount of information a computer can store is measured in bytes.
A BYTE is one character. A character can be a number, letter, or symbol.
A byte consists of 8 bits or binary digits. A bit is the smallest unit of information a computer can process.
A bit is one digit in a binary number; that is either a zero or a one.
Kilobyte, abbreviated KB = about 1000 characters. This is approximately 1 page of double spaced text.
Megabyte, abbreviated MB = about 1,000,000 characters. This is approximately equal to a novel.
Gigabyte, abbreviated GB = about 1,000,000,000 characters. This is approximately equal to 1000 novels.
CENTRAL PROCESSING UNIT (CPU): the part of the computer hardware that controls processing functions.
COPYRIGHT LAWS: a body of exclusive rights that protect the work of authors, artists, computer programmers, and other creative people against copying.
CURSOR: an indicator, frequently a blinking arrow or line, that indicates the point of operation on the screen.
DATA: the facts that a computer system processes.
DEFAULT: a value that is used in a program when the user does not specify a value.
DISK DRIVE: common storage device that magnetically records data on the surface of a rotating disk.
DOCUMENTATION: written material accompanying a software package or hardware system that instructs on its usage.
ENTER/RETURN KEY: key that, when pressed, moves the text insertion point to the start of the next line.
FILE: a unit of storage for a collection of related information.
GRAPHICAL USER INTERFACE ENVIRONMENT (GUIE): a way of interacting with a computer that uses a mouse and icons to initiate actions.
HARD DRIVE: a circular, flat surface on which data in the form of a digital signal is recorded as magnetic impulses.
HARDWARE: the visible, touchable parts of a computer.
KEYBOARD: a typewriter-like layout of keys used to enter text information; an input device.
MONITOR: computer display device; an output device.
MOUSE: a palm-sized pointing device used to control the cursor on a computer screen/monitor; an input device.
PERIPHERAL: a computer attachment such as a scanner, a speaker or a printer.
PRINTER: an output device that produces print on paper.
RANDOM ACCESS MEMORY (RAM): memory in the computer that is lost when the power is turned off.
READ ONLY MEMORY (ROM): memory in the computer that retains its contents even when the power is off.
SOFTWARE: the invisible, electronically stored instructions that tell a computer what to do.
