It is a software interface designed to standardize and simplify the use of computer programs, as by using a mouse to manipulate text and images on a display screen featuring icons, windows, and menus.
GUI is also an interface between a user and a computer system that involves the use of a mouse-controlled screen cursor to select options from menus, make choices with buttons, start programs by clicking icons, etc.
Word Processor
| A word processor (also more formally known as a document preparation system) is a computer application used for the production (including composition, editing, formatting, and possibly printing) of any sort of viewable or printed material. They are descended from early text formatting tools (sometimes called text justification tools, from their only real capability). Word processing was one of the earliest applications for the personal computer in office productivity. Although early word processors used tag-based markup for document formatting, most modern word processors take advantage of a graphical user interface. Most are powerful systems consisting of one or more programs which can produce any arbitary combination of images, graphics and text, the latter handled with full-blown type-setting capability. |

A word processor, or word processing program, does exactly what the name implies. It processes words. It also processes paragraphs, pages, and entire papers. Some examples of word processing programs include Microsoft Word, WordPerfect (Windows only), AppleWorks (Mac only), and OpenOffice.org.
The first word processors were basically computerized typewriters, which did little more than place characters on a screen, which could then be printed by a printer. Modern word processing programs, however, include features to customize the style of the text, change the page formatting, and may be able to add headers, footers, and page numbers to each page. Some may also include a "Word Count" option, which counts the words and characters within a document.
While all these features can be useful and fun to play with, the most significant improvement over the typewriter is the word processor's ability to make changes to a document after it has been written. By using the mouse, you can click anywhere within the text of a document and add or remove content. Since reprinting a paper is much easier than retyping it, word processing programs have make revising text documents a much more efficient process.
The term "text editor" can also be used to refer to a word processing program. However, it is more commonly used to describe basic word processing programs with limited features.
Spreadsheet
A spreadsheet is a grid that organizes data into columns and rows.
Spreadsheets make it easy to display information, and people can insert formulas to work with the data. For example, there is a particular icon that has a formula to sum up numbers that are given. This icon is called auto sum. Information can also be sorted and filtered.
People use spreadsheet programs to learn about different kinds of things, and to make decisions. Spreadsheets are based on different varieties of subjects. This site will highlight the use of spreadsheets in the classroom. You will find ideas for every subject. On this website, we will be using Microsoft Excel.
