COMPUTER HEALTH AND SAFETY

Computer health and safety is necessary to keep the system in good condition. The system should be kept in the appropriate place where it could get fresh air and temperature. Excessive temperature can harmed the system so it should be kept in appropriate place. We should protect the system from the dust particles. Regular back up of crucial document and file is necessary in order to protect from the loss of data. updated anti-virus program should be installed to the system to protect from the access of malicious and spy ware programs(which has the destructive nature).so these types of precautions should be followed to keep the computer in the proper condition. Noise is an inevitable part of the office life, and most of us are able to filter out and ignore sounds, which mean little to us. Noise becomes a nuisance when it exceeds levels, which we can ignore, even when the content of the sound is irrelevant to what we are doing. Our ability to hear serves primarily as a means of communication between individuals, but it has a secondary role as an alarm mechanism. Unexpected, unfamiliar or loud noises trigger hand to the interpretation of sound and preparation of an appropriate response. if this happens regularly, it becomes more difficult to concentrate. Being in a constant state of mild alarm is also exhausting, making comparatively mild noise levels distracting during the office work.

PROCESSOR

Actually the brain of computer is known as the processor because processor interprets the entered data and gives the result back. The processing speed of computer depends upon the varieties of processor. Intel core, AMD and NVIDIA are the processors which are found in the market. Intel core i7 is the latest processor which has high processing speed around 3 MHz. the operations, a microprocessor performs are called the instruction set of this processor. Processors differ from one to another by the instruction set. If the same program can run on two different computer brands they are said to be the compatible. Programs written for IBM compatible computer will not run on an apple computer because these two architecture are not compatible.

Mainframes are early minicomputers contained circuit boards full of integrated circuits cards that implemented the central processing unit. Todays single-chip central processing units, called microprocessors, make personal computers and workstations possible. The CPU has the ability to fetch, decode, and execute instructions and transfer information to and from other resources over the computer main data transfer path, the bus. By defination, the CPU is the chip that functions as the "brain" of the computer. In some instances, however the main computer console (as opposed to peripheral equipment).

MOTHERBOARD

Motherboard is one of the main part of computer system whole system parts and cables are attached with the board so it is one of the crucial and reliance part of computer therefore it is called motherboard. Motherboard is categorized in two types they are

Pin and pin less. Pin less motherboard are expensive than the pin one. Motherboard also can be further categorized as ATX and BTX on the basis of SMPS. IBM decided that there are two types of technologies, which were being used to make personal computer they are:
(1)bus based computers
These bus based computers have used the main board as the backbone of the computer system. This bus board contains number of buses through which the data can be sent from one place to another and it also contains the number of slots onto which we can connect various different devices. Mainly the expansion cards are connected onto the expansion slots. In this types of bus based computer there are three buses.
1address bus
2data bus
3control bus
(2) single board based computers
The other approach in the computer design is a single board based systems. These types of boards are easy to manufacture and design and it is less expensivethan bus based type of computer. the video games computers and home computers are generally this types of system. In these systems we, cannot connect any other additional devices
There is no scope or having of upgrading or adding any new device introduce in the market to these systems. In these systems if any of the component fails, the user will have to discard the complete circuit board means that we cannot repair its any of the component.

TELECOMMUNICATION

Telecommunication is also one of the great discover in the field of technology. People can share their information through the help of telecommunication. Large no of people can talk at the same time from the different location of the world because the introduction of telecommunication. Large no of tower are have been erected in the rural areas, Town, hill and on those place where telecommunication are essential. Networks are building up with concept of telecommunication. Different telecommunication center are providing the internet to subscribers. Networking is the process of connecting one computer terminal with others . a communication system that enables many users can be called a network or we can say network is a communication system , which interconnects many users who have something in common, either with respect to the type of data being sent or to the geographic areas that the users cover. Networks can be used between computers. Today organizations use networks in all possible ways. Depending on the application, the network needs different speed, degree of reliability, and cost. One of the largest networks in the world is at NASA. This network combines all of the world wide space tracking stations, the NASA research facilities, and the NASA operational offices. data from any location can be instantly sent to any other ,as can memos, messages, and conversations. multiple nodes  of the computer, which are connected with each other are called computer network. A computer network is created when several computers and terminal are connected together by a data communication system.

COMPUTER GAMES

Computer games are made for the entertainment. It is the mostly incredible for those who are the freak of computer games. Computer games are also one of the source points for getting tremendous entertainment due to its graphics, simulation and animated motion. Computer
Games have occupied the space to create a amusing environment in the field of entertainments. computer games are fantastic . it is noticed that the computer games were started in the 1970 when the earliest computer video games such as pond appeared in the bars and gaming arcades. The video games came to the living rooms with the advent of atari, nintendo an sega console game players which are special purpose computers. Games soon migrated to the personal computers and from there, to the internet.there are various computer ganmes that runs on various platform.computer games are mostly used as a source of entertaintment so it many bars used to keep computer games to attract the mind of children and other people.computer games is one of the software that is made from the various components.it needs a group work to release.somer of the group are responsible for programming, some for graphic editing,sound effects,animation and finally for testing and implementing.

ARTIFICIAL INTELLEGENCE

Robotics, animated movies are the example of the artificial intelligence. According to the investigators computer can understand the human language and ambiguities of people. It is an advanced concept of computer science that studies how human thinks and then attempts to apply that knowledge in hardware and software to give computer similar capabilities. Areas of research include speech and pattern recognition the ability to perform language translation, natural language processing, the ability to learn from previous experience, and ability to reason under the conditions providing only incomplete information. Practical applications for AI range from medical diagnostics to computer configuration and the interpretation of oil well logging data. In artificial intellegence, problem solving and decision making system that uses a computer representation derived from the knowledge and experience of a human expert called expert system. An expert system consist two parts the domain or database of factual knowledge about the subject, and a set of rules that provide a method of using that knowledge.
Expert systems are usually confined to a very narrow area of expertise. This is also known as rule based system
