Cards

Term
Data
Definition

Information in a form that can be read, used, and manipulated by a computer

 

Data is the raw information that one can take in order to make an educated decision.

 

Ex: Facts, statistics, Snapple caps

Term
Information
Definition

Anything that can be communicated.

 

Information can be seen as anything that has the ability to inform.

 

Ex: Data, statistics

Term
Hardware Components
Definition

Physical parts of the computer system.

 

Hardware is the physical pieces of a computer that one interacts with when working with a computer.

 

Ex: Monitor, keyboard, printer

Term
Input Devices
Definition

Device for accepting input. They accept from the outside.

 

Input devices work as a way to enter information into the computer system. This is the way a user can interact with the computer.

 

Ex: Keyboards, pointing devices

Term
Output Devies
Definition

Device for sending information from the computer. They send information to the outside world.

 

Output Devices are the opposite of Input Devices and they act as a way for a computer to interact and communicate with the user or other outside party.

 

Ex: Video monitors, printers, speakers

Term
Processing
Definition

An activity that manipulates and organizes information in ways that add value.

 

Processing is the one of the baisc functions of a computer and it is its ability to work or perform a task with the data it has reieved

 

Ex: Calculate the total grocery bill during checkout

 

Term
Storage
Definition

Long-term repository for data. A way to save data or information for later use.

 

Storage is a vital part of computers because it allows computers to keep memory of information, whether it be basic start up procedures or applications.

 

Ex: Disks and tapes can be used to store information on a computer

Term
Memory
Definition

Stores programs and the data they need to be instantly accessible to the CPU.

 

A computer's memory is used to store program and data that needs to be instantly accessible to the CPU

 

Ex: ROM, RAM

Term
MHz (Megahertz)
Definition

Millions of clock cycles per second, a measurement of a computer's clock speed.

 

Hertz (Hz) is the technique used to measure a computer's clock speed

Ex: 1 MHz = 1,000,000 Hz  

Term
dpi (dots per inch)
Definition

A measurement of the density of pixels, defining the resolution of a graphic.

 

dpi is used mostly in images in order to determine the quality of a graphic. The higher the dpi means the more pixles in a one inch area, meaning the resolution will be better.

 

Ex: 100 dpi

 

Term
KB, MB, GB, TB
Definition

All are forms of storage and memory capacity. They measure the number of bytes of storage, with prefixes like Mega, Giga, and more.

 

Bytes are a way to quantify the amount of memory a computer has and acts as a way to show the user the space used and space avalible

 

Ex: 1 KB = 1,000 bytes; 1 GB = 1,000,000,000

Term
Peripheral
Definition

An external device, such as a keyboard or monitor, connected via cables to the system central processing unit.

 

Peripheral are the external devices that are a large part of the comptuer system, such as the input, output, and storage devices

 

Ex: Monitor, keyboard

Term
Platform
Definition

The combination of hardware and operating system software upon which application software is built.

 

Plaform is used to describe the combination of hardware and operating system software on which application software is built. Needed for software to be built.

 

Ex: Windows, Mac
