explain by the application of computer in information technology?how are the computer used in CAD?write advantages to use CAD?

APPLICATION OF COMPUTER IN INFORMATION TECHNOLOGY:
information technology is concerned with the use of technology that manged and processes the information, especially in large organization. computer are used to store, retrieve, process and transmit information. anything that involves with the computers, software's, networks, internet, websites, servers, databases and telecommunication, relates to information technology. most of the business depends largely on information technology from e-mail to database management.
APPLICATION OF COMPUTER INDUSTRY:
computer are used in many industrial files. the main area among them are:
. computer aided designs
COMPUTER AIDED DESIGNS (CAD):
in main industrial, CAD software are used to network designs. A ACD system is a combination of hardware and software that enables engineers and architects to make simple as well as complex designs.

personal computer can be used to run CAD software. for this PC's should have high-resolution graphic monition, light pen and graphic table for drawings. special printers e.g. plotters are used to print complex designs.

CAD in mainly used for 2D or 3D drawings. these drawings can be saved for future use. CAD allows easy editing and improvement of drawings. this task would be time consuming if done manually.

Advantages of Computer Aided Designs:
. drawings are precise.
. 3D details of drawings give a better pictures.
. designs are cheats and easy to produce.
. images / drawings made in CAD can be seen in animation. this gives us the real of the project, before having to build it.
CAD for Aircraft:
designing an aircraft is very complex job. for the past many years, the aircraft industry designed all aircraft manually. now this laboriously manual task of designing may be accomplished by CAD. without the help of a CAD system, it is impossible to design and maintain thousands of design sheets
the present design and layout of aircraft entirely done by the computer. the speed, accuracy and large storage capabilities have made the computer a particular tool for designing.
CAD for homes and offices:
CAD software can be used to design home and offices. for example, smart draw is CAD software to make designs of homes and offices. you can use it to make simple designs of your homes.
Computer Aided Manufacturing (CAM):
CAM is a system of using computer technology to control manufacturing process. computer aided designs can be loaded to CAM machines. these machines are controlled by computers to work more efficiently than finest craftsmen.
