Computer Networking

A computer network, often simply referred to as a network, is a collection of hardware components and computers interconnected by communication channels that allow sharing of resources and information. Technically, Network is defined as "If at least one process in one computer is able to send/receive data to/from at least one process residing in a remote computer, then the two computers are said to be in network".(http://en.wikipedia.org/wiki/Computer_network). Computers need to communicate each other, most of companies, educational institutions, and such things of sharing files disseminating information. Networkings are widely used of telecommunication, using communication media, coaxial cable, twisted pair and fiber optic cable. Coaxial cable had suffered waning popularity, but is making a bit of a comeback with cable modem solutions. There are two types of fiber-optic cable: multi mode fiber and single mode fiber. Twisted pair is the most common type of computer network cabling. Twisted pair can be classified according to the value of the intrinsic impedance of the wire, and whether it is shielded or unshielded. Unshielded twisted pair, with an intrinsic impedance of 100 ohms, is the most common type of computer network cabling used today. Performance of network refers also for cabling used most commonly problems occurred are the transmission of computers connected to the network. The fiber is the best cable used for communication, telephones, internet television, and Internet service providers etc., using this type of cabling or fastest transmission of information connected to their network. The demand of computer networking in different fields now a days are closely primary needs that engage in computer technology. With the updates of computer networking today, different offices, businesses, and government and in home has communication with other computers, laptops, netbooks, cellphones and etc. Aside cables, networking devices such as routers, switches, etc. Most common cables used in networking are CAT5 cable (UTP Cable) Unshielded Twisted Pair, and also using the rj45 connector to be attached in switch or router. Class A, B and the crossover connected being used in our society today, because much expensive compare to fiber optic. Communication inventions are most of the trend in the world today, cellphones, desktop and laptop computer are fast growing demand in the market. Networking using cables and thru wireless computers can connect to each other even gadgets that are connected using “wifi”.

            Finally, with the networking using computers and other gadgets people can do anything to their wants using the updated technology. Computer networkings are primary sources of information worldwide. News, entertainment, business now a day’s should be browse using internet. On-line business and bank transaction, are been made it. The demands of technology today are focusing in networking
 as a invention contribution in our society. Lifestyle of people has been change with our technology of computer world and probably the character also must change. Computers has a good and bad effects in our society, computer games, social networking, sometimes it gives us doubt to us especially in the communication of every people. Networking make it in the technology provides a wonderful invention to us.

HOW DOES THE COMPUTER BEING IMPORTANT AT THIS TIME?

Important because it is using in different such fields. In offices, schools and even at home. Here you see how much you value a person’s the importance of computer. As students it is important for many of us can. Creating reports, computation and other important activities using the computer. Not only for an individual computer is being use, it is the entire family be an example is the chat this way and you can communicate your loved ones.

So should not mistreat the use of computers because it depends only on the user, sometimes with questions “Who Is Wise Computer or Person Do?” But the simple answer to that question, whether intuitive or mold depending on this user due to ill children as other students escape their classes especially to play online and LAN games, these should not see children as internet porn viewing so the computer has three categories; hardware, software, and people ware. The people ware all should guide the parents to their children not yet 18 years old.
Measure only the importance of computer is the expert in using it and even new technologies that being exist today. The Computer Science / Programming and Hardware Servicing seemed to know the field of Computer especially in troubleshooting. Computers are primarily source of information with daily news, updates in such different fields worldwide.

Most of company’s were using computer in their daily transactions, communicating with co-company’s using computers does not need additional manpower for company to make of the company’s expenses. Now a day, computers are most commonly used of everybody worldwide to viewing different websites connected to the web. Internet one of the successful invention and technology upgrades in the world. INFORMATION COMMUNICATIONS TECHNOLOGY which have a biggest part in information and communication contribution worldwide. With media, such as radio televisions newspaper and even internet gives information in our community. Computer Education aims that is to education students to molds in every programming languages, technical activities and troubleshooting. Most educational Institution is engage in on-line transaction such as on-line registration, viewing of grades and for advertizing purpose. Electronics are also linking with software developer to upgrade their hardware components to upgrade their software side. Hardware and software are both linking their updates in every additional invention towards the improvement of our technology today. Programmers and technical experts are also sharing their skills thru internet without gaining money for posting the possible solution for asking problems encountered by the end-user of different technology. Computer technology widely experiencing the heaviest responsibility especially those on-line companies, government, public and private institutions.

Therefore, e-campus for the educational institution, e-government for government and e-company for company using electronics equipment to operate and to have a centralized system. Computerized-based systems are mostly of the company was implementing to monitor their employee and it can be accurate and reliable records and also for the retrieval for the records if in case the system was been down. ICT personnel are those persons who are liable to have an authority to troubleshoot if the problems were occurred in the system.

Finally, ICT are widely contribution in our inventions and upgrades in our technology both technical and programming aspects.
