Glossary
Algorithm Code
A system of coding data by the use of combination of letters to represent item of information.
Alphanumeric Code
Pertaining to character set or field of data in which the coded characters may represent numerals or letters of the alphabets.
Analog Computers
Analog computers are machines designed to perform arithmetical functions upon numbers where the numbers are represented by some physical quantity.
Introduction to Windows Operating System
Windows Desktop
Windows “Desktop” is like a working surface of a desk. Desktop is where your applications, folders and shortcuts are located. Desktop contains the following items.
1. Icons
2. Taskbar
3. Start Button
The function of these desktop items is given below:
1. Icon
An icon is a small colourful graphical picture that represents an object like a file, folder, program or any hardware components of the computer. Every icon has a lable, which identifies it. The labels can be changed.
Computer Software
Machine Language
Machine language is the only language that a compute understands directly without any translation, it is the binary language. It is the language of 0’s and 1’s . It consists of strings of binary numbers.
The binary codes are very difficult to memorize for human beings that is why a machine language is cumbersome for a user.
Difference Between a High-Level Language and Low-Level Language
High-Level Languages
High-Level language are more suitable for human use than machine languages and enable the programmer to write instructions easily using English words and familiar mathematical symbols. These symbolic languages are called High-Level languages. These high-level languages consist of simple English sentences, which are very easy to understand and memorize for human being.

Boolean Algebra
Boolean Algebra
The Boolean algebra was developed by the English mathematician George Boole; it deals with statements in mathematical logic, and puts them in the form of algebraic equations. The Boolean algebra was further developed by the modern American mathematician Claude Shannon, in order to apply it to computers. The basic techniques described by Shannon were adopted almost universally for the design and analysis of switching circuits. Because of the analogous relationship between the actions of relays, and of modern electronic circuits, the same techniques which were developed for the design of relay circuits are still being used in the design of modern high speed computers. Thus the Boolean algebra founds its applications in modern computers after almost one hundred years of its discovery.
Boolean algebra provides an economical and straightforward approach to the design of relay and other types of switching circuits. Just as an ordinary algebraic expression may be simplified by means of the basic theorems, the expression describing a given switching circuit network may also be reduced or simplified using Boolean algebra.
