A network is simply the most cost-effective way to share a collection of communication equipment such as servers, computers, printers, and modems, that has been connected together by cables. A network helps people work collectively, not just individually.
Networking is all about sharing data, software, and peripherals such as printers, modems, fax machines, Internet connections, CD-ROM and tape drives, hard disks and other data storage equipment. A small network may be as simple as just two computers linked together by cable. A large network can link hundreds or thousands of computers and peripherals together in various configurations.
A variety of equipment may be used in a network. Depending on how many computers and other equipment you need to connect, your choice of networking devices will vary.
You may want to review the document, Common Network Layouts, to understand when and where these networking products are used and how they can help expand your network. Maintaining standards will ensure the best performance possible. Don't worry?it's easier than you think!
Server
A server can be as simple as a dedicated computer providing file storage, or as complex as a high capacity computer containing several hard disk drives, and a tape backup and CD-ROM drive. It can be used to help share resources such as printers, fax machines, modems, and connections to the Internet. It is often used to store database information, multiple software programs for access by "client" computers, work files on its large hard drive, and archive files. Computers connected to a server are called "clients."
Why Do I Need A Network?
A network will actually save you time and money! In today's business, the need for information is expanding so quickly that networking is no longer a luxury; it's an affordable necessity.
To be successful, businesses must share information and communicate not only within their company, but to the outside world. Networking makes this happen in the simplest and most economic way. Additionally, a network can eliminate the need to buy extra printers, modems, file storage, etc.: all of these items can be shared on a network. Even an outside line for Internet access can be shared over a network. It's obvious why a network is important?even essential?for growing businesses.
What Makes It Work?
Ethernet refers to the most common networking system. When Ethernet+ was established, certain standards were set. All messages sent over an Ethernet network include exact codes within the transmission that allow another device to accept them. Information is sent in small bursts of data, called "packets", to ensure that the send and receive operation is completed correctly.
+ Ethernet
A networking system originally developed in 1973 by Xerox and formalized in 1980 by DEC, Intel, and Xerox which transmits data at 10Mbps using specific methods.
