A CAD system is a combination of hardware and

software that enables engineers and architects to

design everything from furniture to airplanes.

In addition to the software, CAD systems

require a high-quality graphics monitor; a mouse,

light pen, or digitizing tablet for drawing; and a specialprinter or plotterfor printing design specifications.

CAD systems allow an engineer to view a

design from any angle with the push of a

button and to zoom in or out for close-ups

and long-distance views. In addition, the

computer keeps track of design dependencies

so that when the engineer changes one value,

all other values that depend on it are

automatically changed accordingly.

Until the mid 1980s, all CAD systems were

specially constructed computers. Now, you

can buy CAD software that runs on

general-purpose workstations and

personal computers

• 1.Computer-aided engineering (CAE) is the process of solving engineering problems through the use of sophisticated, interactive graphical software.

2.CAE is one of the leading softwares employed by manufacturing organizations to mass produce products in a factory-based environment. It allows for more computations than is possible by hand, especially

when it is coupled with

optimization system

Weather forecasting is the application of science and technology to predict the state of the atmosphere for a given location. Human beings have attempted to predict the weather informally for millennia, and formally since the nineteenth century. Weather forecasts are made by collecting quantitative

data about the current state of the atmosphere

on a given place and using

scientific understanding

of atmospheric processes

to project how the

atmosphere will change

Determining the location of an earthquake And Recording earthquakes.Nuclear testing : it studied by used of computer.Pollution : how pollution will affect weather can be predicated using computer Outer space ,soloar system and cosmos are explored using computer Intricate molecles are designed ,diagrammed and manipulated using computer.Business clearly see the interest as a way to enhance productivity and competitiveness. Some areas of business that are undergoing rapid changes are sales and marketing, retailing, banking, stock trading, etc. Sales representatives not only need to be better educated and more knowledgeable about their customer’s businesses, but also must be comfortable with computer technology.Computers have aided in the design of safety equipment in sports such as football helmets to shoes to mouth guards.DEFENCE • There are many uses computers in Defence such as: Controlling UAV or unmanned air-crafts an example is Predator.

A computer network or data network is a telecommunications network that allows computers to exchange data. In computer networks, networked computing devices pass data to each other along data connections. Data is transferred in the form of packets.

The connections (network links) between nodes are established using eithercable media or wireless media. The best-known computer network is the Internet.

Network computer devices that originate, route and terminate the data are called network nodes.

Nodes can include hosts such aspersonal computers, phones, servers as well as networking hardware.

Two such devices are said to be networked together when one device is able to exchange information with the other device, whether or not they have a direct connection to each other.

Computer security is security applied to computing devices such as computers and smartphones, as well as computer networkssuch as private and public networks, including the whole Internet. The field covers all the processes and mechanisms by which digital equipment, information and services are protected from unintended or unauthorized access, change or destruction, and is of growing importance due to the increasing reliance of computer systems in most societies. It includes physical security to prevent theft of equipment and information security to protect the data on that equipment. It is sometimes referred to as "cyber security" or "IT security". Those terms generally do not refer to physical security, but a common belief among computer security experts is that a physical security breach is one of the worst kinds security breaches as it generally allows full access to both data and equipment.security categories Cyber security and countermeasure

Graphics ( 'something written' e.g. autograph) are visualimages or designs on some surface, such as a wall, canvas,

screen, paper, or stone to inform, illustrate, or entertain. In contemporary usage it includes: neeke, pictorial representation of data,

as in computer-aided design and manufacture, in typesetting and the graphic arts, and in educational and Neeke recreational software. Images that are generated by a computer are called computer graphics.Examples are photographs, drawings, Line Art, graphs, diagrams, typography, numbers, symbols, geometric designs,maps, engineering drawings, or other images. Graphics often combine text, illustration, and color. Graphic design may consist of the deliberate selection, creation, or arrangement of typography alone, as in a brochure, flyer, poster, web site, or book without any other element. Clarity or effective communication may be the objective, association with other cultural elements may besought, or merely, the creation of a distinctive style.Graphics can be functional or artistic. The latter can be a recorded version, such as a photograph, or aninterpretation by a scientist to highlight essential features, or an artist, in which case the distinction with imaginary graphics may become blurred.

Computers are used in banks for storing information about different account holders.

Computers help in keeping a record of the cash.

Computers help in giving all kinds of information regarding any account in the bank

Computers help in keeping records of all the patients in a hospital.

Computers help doctors in controlling operation theatre machines.

Computers help in doing a number of medical tests.
