Computer Network

The network is a collection of computers, software, and hardware that are all connected to help their users work together. Networks connect computers in a way cable systems, special software, and devices that manage data traffic. The network allows users to share files and resources, such as printers, and send electronic messages (e-mail) to each other.
computer networks are divided into two main types: / network client server and peer-to-peer network. A client / server network using one or more specific machine (server) to share files, printers, and applications. A peer-to-peer allows users to share files with other users and do not require a server, a dedicated center.
Most common network of Local Area Network or LAN for short. A LAN connects computers in a single geographic location, such as an office building, office suite, or home. In contrast, Wide Area Network (WAN) span different cities or even countries, using telephone lines or satellite links.
Networks are often categorized in other ways, too. You can refer to the network with what kind of computer circuit boards that are used to connect to each other - Ethernet and Token-Ring is the most popular choice. You can also refer to the network how the packet data for transmission cable, with terms such as TCP / IP (Transmission Control Protocol / Internet Protocol) and IPX / SPX (Internet Packet eXchnage / Sequenced Packet eXchange).
Steps to Setting-Up Networking.
All the networks through roughly the same steps in terms of design, launch, configuration, and management.
Designing Your Network
Plan the design stage to take anywhere from one to three business days, depending on how much help you have an ad on how big your network.
Here are the key tasks:
Settle on a peer-to-peer or client / server network.Select your network system software.Choose the language network.Figure out what hardware you need.Decide what security level the information you need.Selecting software and hardware solutions to handle the tasks of daily management.Rolling Out Your Network
Deploying your network requires the following steps:
Run and test network cables.Install the server or servers if you set up the client / server network.(If you set up a peer-to-peer, you usually do not have to worry about any dedicated server.)Set the workstation hardware.Plug and Cable Network Interface Cards (NICs - This network connects to the LAN).Install the hub or hub (if you use twisted-pair cable).Install the printer.Loading the server software (NOS, or Network Operating System) if your network is client / server type.Install the workstation software.Install modem hardware for remote Dail-up (if you want users to dial into the network).Install the program you want to run (software applications).Configuring Your Network
means to adjust the network configuration network for your own use.
Creating a network for your user account (name, password, and group).Creating a shared area on the disk drives for users to share data files.Creating a shared area on the disk drives for users to share programs (unless every person running the program from their own computers.)Setting up the print queue (software that lets users share a network printer).Support network installation on user workstations, so they can "talk" to your network.Managing Your Network
The work you do after your LAN up and running and configured to save a large amount of time in the coming months.
Mapping your network for easy management and troubleshooting.Setting up security measures appropriate to protect against the dangers of accidential and deliberate.Tuning up your LAN so you get the best speed out of it.Creating a corporate standard for adding hardware and software, so you do not have compatibility problems interfere with later.Putting a backup system in place so that you have copies of data and programs if your hardware fails.Install some monitoring and diagnostic software so you can check the health of your network and get early warning implending problem.Finding out how you plan to handle the problem - educating the LAN administrator, setting up a support contract with the software vendor, and so forth.Smooth Setup
One of the main advantages of a peer-to-peer is that it is easy to setup. With a simple type of peer-to-peer, you only use the built-in networking that comes with your operating system (Windows 98, Windows 95, MacOS, etc.) and you have very little software to set up - even less if you have computer that has a preinstalled operating system, like most of today's computers.
For Windows 95 and Windows 98, the basic steps to create a network of peer-to-peer is as follows:
Sketch map of your workgroup.Image of a naming convention (rules established for naming each computer).Go to the first computer on your network and click Start - Settings - Control Panel.Double-click the Network icon to display the Network dialog box.Click the Configuration tab (if not already in the foreground).Click File and Print Sharing button.Click the checkbox so it appears checked, then click OK.Click the Identification tab.Creating a workgroup member computers by typing the name of the workgroup in Workgroup: text box.Give your computer a unique name in Computer name: text box.Repeat steps 3-10 for each workstation in your new workgroup.Teach all network users how to share files, directories, and printers.Another key advantage of peer-to-peer is that you do not need to buy a computer that can not be used as a workstation client (something that the client / server network requires). Peer-to-peer networks offer another cost advantage:
This software is usually free. It either bundled with the operating system or an additional low-cost workstations.The software is simple. You do not need to spend money and time it takes someone training to learn, complex, full-featured Network Operating System.Administration & easy. Every user is administrator of small-scale network, which is responsible for any computer user on the network share.
