Basic terms in IT

Information Technology consists of all forms of technology used to create, store and exchange information in various forms, i.e. it incorporates all computerized and automated information handling including system design and analysis, conversion of data, computer programming, information storage and retrieval, voice, video and data communications.

Over the last decade, organizations worldwide have transformed the way they do business by investing millions of dollars in IT. Today information technology is not just computer literacy. It also takes into account how computers work and how these computers can further be used not just for information processing but also for communications and problem solving tasks as well. The impact of information technology has been felt all over the world and in all areas of life like Education, Entertainment, Scientific Applications, Artificial Intelligence and Robotics etc.

Below is the list of some basics terms related to Information Technology which you need to know:

• Application Software: Software that has been developed with an intention to solve a particular problem is called application software.
• Arithmetic and Logic Unit (ALU): It performs mathematical, logical and decision operations in a computer. It is made up of devices called gates that receive one or more inputs and,based upon what function they are designed to perform, output a result.
• Assembler: An assembler is used to convert the code program written in assembly language into a machine language code.

Asynchronous Mode: In asynchronous mode of data transmission,at a time only one byte of data can be sent or received.

• Asynchronous Mode: In asynchronous mode of data transmission,at a time only one byte of data can be sent or received.
• Bandwidth: Bandwidth is defined as the range of frequencies that any medium can pass through.
• Bar Code Reader: In bar code reader, the bar coded item is gone through a laser scanner or a stick is moved the bar code to read in the data. It somewhat similar to a scanner but it is much simpler in nature. It is commonly used at supermarket checkouts, malls in big cities, digital libraries etc.
• Bit Stream: Bit stream is defined as a grouping of data units in the form of bits. Bit streams are generally represented in the form of 0s and 1s.
