Spread sheet

A table of values arranged in rows and columns. Each value can have a predefined relationship to the other values. If you change one value, therefore, you may need to change other values as well.

Spreadsheet applications (sometimes referred to simply as spreadsheets) are computer programmes that let you create and manipulate spreadsheets electronically. In a spreadsheet application, each value sits in a cell. You can define what type of data is in each cell and how different cells depend on one another. The relationships between cells are called formulas, and the names of the cells are called labels.

Once you have defined the cells and the formulas for linking them together, you can enter your data. You can then modify selected values to see how all the other values change accordingly. 

DBMS

A collection of programs that enables you to store, modify, and extract information from a database . There are many different types of DBMSs, ranging from small system that run on personal computers to huge systems that run on mainframes . 

 Utility Suites 
A program that performs a very specific task, usually related to managing system resource. 
Operating system contain a number of utilities for managing disk drives, printers, and other device.




Audio Editing Software

The process of manipulating video images. Once the province of expensive machines called video editors, video editing software is now available for personal computers and workstations . Video editing includes cutting segments (trimming), re-sequencing clips, and adding transitions and other special effects.

This is actully a mixer for professionals in editing music .

Bitmap

Short for "Bitmap." It can be pronounced as "bump," "B-M-P," or simply a "bitmap image." The BMP format is a commonly used raster graphic format for saving image files. It was introduced on the Windows platform, but is now recognized by many programs on both Macs and PCs.



The BMP format stores color data for each pixel in the image without any compression. For example, a 10x10 pixel BMP image will include color data for 100 pixels. This method of storing image information allows for crisp, high-quality graphics, but also produces large file sizes. The JPEG and GIF formats are also bitmaps, but use image compression algorithms that can significantly decrease their file size. For this reason, JPEG and GIF images are used on the Web, while BMP images are often used for printable images.

Desktop publishing programme 

iStudio

Desktop publishing software is a tool for graphic desginers

and non-desginers to create visual for communications for professionals or desktop

Vector Image

An example of a vector image .

Vector graphics formats are complementary to raster graphic, which is the representation of images as an array of pixel , as is typically used for the representation of photographic images. There are instances when working with vector tools and formats is the best practice, and instances when working with raster tools and formats is the best practice. There are times when both formats come together. An understanding of the advantages and limitations of each technology and the relationship between them is most likely to result in efficient and effective use of tool
