Intro to IT

GRAPHICAL USER INTERFACE (GUI)

Graphical user interface is a type of program interface that uses a combination of technologies and devices to provide a base that enables the user to interact with, for the tasks of gathering and producing information. For example, computers, MP3 players, portable media players, gaming devices, household appliances and office equipments. GUI takes  advantage of the computer's graphics capabilities to make the program easier to use.


WORD PROCESSOR

Word processor is a computer application that is used for the production, which includes composition, editing, formatting, and possibly printing, of any sort of printable material. Some examples of word processing programs include Microsoft Word, WordPerfect (Windows only), AppleWorks (Mac only), and OpenOffice.org. The greatest advantage of word processors over using a typewriter is that you can make changes without retyping the entire document.



SPREADSHEET

A spreadsheet is a document that stores data in a grid of horizontal rows and vertical columns.  Rows are typically labeled using numbers (1, 2, 3, etc.), while columns are labeled with letters (A, B, C, etc). Individual row/column locations, such as C3 or B12, are referred to as cells. Each cell can each store a unique instance of data. Spreadsheets are frequently used for financial information because of their ability to re-calculate the entire sheet automatically after a change to a single cell is made.




DATABASE MANAGEMENT SYSTEM

A database management system is a program that lets one or more computer users to create and access data in a database. It is a part of a data processing system, which aids in the storage, manipulation, reporting, management, and control of data. It manages user requests so that users and other programs are free from having to understand where the data is physically located on storage media and, in a multi-user system, who else may also be accessing the data.


UTILITY SUITES

Utility suites is a combination of many utility softwares that combines specific tasks related to the management of computer functions, resources, or files, as password protection, memory management, virus protection, and file compression into one piece of software. They help analyze, configure, optimize and maintain the computer. Utilities are often rather technical and targeted at people with an advanced level of computer knowledge as they usually focus more on how the computer infrastructure operates.
