Computer Networking & Internet




Computer networking management means different things to different people. In some cases, it involves a solitary network consultant monitoring network activity with an outdated protocol analyzer. In other cases, computer networking management involves a distributed database, auto polling of network devices and change traffic of network topology. Computer networking management is a service that employs a variety of tools, application and devices to assist human network in monitoring and maintain networks.
Computer networking architecture uses the same basis structure and set of relationship. Computer networking architecture management entities can also poll and stations to check the values of certain variables. Simple networking management protocol  and common management information protocol  are also including.
Computer networking management tools has contributed a great deal to network standardization. Its network management model is the primary means for understanding major functions of networking management system.
The goal of performance management is to measure and make available various aspects of networking performance, so that internet work performance can be maintained at an acceptable level. Performance management involves to gathered varieties of networking administration too. Networking management entities continually monitor performance variables. Performance networking management also permits proactive methods.
The goal of configuration networking management of computer is to monitor network and system configuration information, so that the effects a network operation of various versions of hardware and software elements can be tracked and management. Each network device has a variety of version information associated with it too.
Accounting management also include in computer networking management. Such regulation minimize network problems and maximizes the fairness of network across a;; users. Some correction of course, will be required to reach optimal across practices.
Fault networking management is also detect, log, notify users of load automatically fixed problems to keep network running. It involves first determining systems and isolating the problems.
Security networking management is to control access to network resources according to local guides, so networking cannot be sabotaged. It performs several functions in computer networking management. It monitors access points to sensitive too.
Computer networking software that manages resources on network is often called network operating system (NOS). Some popular networking operating systems are Microsoft windows 2000, Novell networking operating system, Windows server 2000 and so no.
Important of computer networking is can easily and legally share information with other computer. Computer on networking access devices like printer and other connected peripherals. It facilitates backup. Security is also helpful for not providing unauthorized access.
Computer networking with good communication capacity, with sufficient memory, process capacity and NIC (Network Interface Card/Network Card). Data communication also needed in computer networking use of computer networking technology and networking protocol also uses too.
Gateway used in computer networking for large entity too. It is joined together by a high speed link. Gateway is a computer networking management point that acts as to another network too.
Direct connection a dedicated phone line is used for computer networking management too. It can operate kb per second too. It required router which automatically handle connection of computer networking management.
Frame transmission receives a transmits frame request with the accompanying address and data information from layer of LLC sub layer. Frame is assembled, actual frame transmission will depend on whether the MAC is operating in half-duplex and full duplex method.
System consideration might see that it would be no problem to upgrade an existing computer networking management or to plan a new computer networking management. The problem is two fold.
Aompus disturber is also important in computer networking management system. It facility with two or more building in a relatively small area. This control point of the computer backbone and telecom connection point with the outside world.
   
       The Internet is a worldwide, publicly accessible series of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP). It is a "network of networks" that consists of millions of smaller domestic, academic, business, and government networks, which together carry various information and services, such as electronic mail, online chat, file transfer, and the interlinked web pages and other resources of the World Wide Web (WWW). 


COMMON USE OF INTERNET 


[1]E-mail 
The concept of sending electronic text messages between parties in a way analogous to mailing letters or memos predates the creation of the Internet. Even today it can be important to distinguish between Internet and internal e-mail systems. Internet e-mail may travel and be stored unencrypted on many other networks and machines out of both the sender's and the recipient's control. During this time it is quite possible for the content to be read and even tampered with by third parties, if anyone considers it important enough. Purely internal or intranet mail systems, where the information never leaves the corporate or organization's network, are much more secure, although in any organization there will be IT and other personnel whose job may involve monitoring, and occasionally accessing.
[2]TheWorldWideWeb

The World Wide Web is a huge set of interlinked documents, images and other resources, linked by hyperlinks and URLs. These hyperlinks and URLs allow the web-servers and other machines that store originals, and cached copies, of these resources to deliver them as required using HTTP (Hypertext Transfer Protocol). HTTP is only one of the communication protocols used on the Internet. 
Web services also use HTTP to allow software systems to communicate in order to share and exchange business logic and data. Software products that can access the resources of the Web are correctly termed user agents. In normal use, web browsers, such as Internet Explorer and Firefox access web pages and allow users to navigate from one to another via hyperlinks. Web documents may contain almost any combination of computer data including photographs, graphics, sounds, text, video, multimedia and interactive content including games, office applications and scientific demonstrations.
[3] File sharing 
Computer file can be e-mailed to customers, colleagues and friends as an attachment. It can be uploaded to a Web site or FTP server for easy download by others. In any of these cases, access to the file may be controlled by user authentication; the transit of the file over the Internet may be obscured by encryption and money may change hands before or after access to the file is given. The price can be paid by the remote charging of funds from, for example a credit card whose details are also passed—hopefully fully encrypted—across the Internet.

[4]Marketing 
The Internet has also become a large market for companies; some of the biggest companies today have grown by taking advantage of the efficient nature of low-cost advertising and commerce through the Internet, also known as e-commerce. It is the fastest way to spread information to a vast amount of people simultaneously. The Internet has also subsequently revolutionized shopping—for example; a person can order a CD online and receive it in the mail within a couple of days, or download it directly in some cases. The Internet has also greatly facilitated personalized marketing which allows a company to market a product to a specific person or a specific group of people more so than any other advertising
Examples of personalized marketing include online communities such as MySpace, Friendster, Orkut, Facebook and others which thousands of Internet users join to advertise themselves and make friends online. Many of these users are young teens and adolescents ranging from 13 to 25 years old. In turn, when they advertise themselves they advertise interests and hobbies, which online marketing companies can use as information as to what those users will purchase online, and advertise their own companies' produce these types.
Today’s internet
The Internet is a worldwide, publicly accessible series of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP). It is a "network of networks" that consists of millions of smaller domestic, academic, business, and government networks, which together carry various information and services, such as electronic mail, online chat, file transfer, and the interlinked web pages and other resources of the World Wide Web (WWW).
