When you use twisted-pair cable to wire a network, you don’t plug the computers into each other. Instead, each computer plugs into a separate device called a network switch.You need to know only a few details when working with network switches. Here they are: Installing a switch is usually very simple. Just plug in the power cord and then plug in patch cables to connect the network.
Windows usually detects the presence of a network adapter automatically. When Windows detects a network adapter, Windows automatically creates a network connection and configures it to support basic networking protocols. You may need to change the configuration of a network connection manually, however.The following steps show how to configure your network connection on a Windows 10 system: Click the Start icon (or press the Start button on the keyboard), and then tap or click Settings.
You can turn your humble Windows client computer running Windows 7, 8, or 10 into a server computer so that other computers on your network can use your printer and any folders that you decide you want to share. In effect, your computer functions as both a client and a server at the same time. A couple of examples show how: It’s a client when you send a print job to a network printer or when you access a file stored on another server’s hard drive.
One of the most useful tools available to system administrators is a program called Remote Desktop Connection. Remote Desktop Connection lets you connect to a server computer from your own computer's desktop and use it as though you were actually sitting at the server. The program enables you to manage your servers from the comfort of your own office, without having to walk down to the server room.
If you often access a particular shared folder, you may want to use the special networking trick known as mapping to access the shared folder more efficiently. Mapping assigns a drive letter to a shared folder. Then you can use the drive letter to access the shared folder as though it were a local drive. In this way, you can access the shared folder from any Windows program without having to browse the network.
When you first create a file share on your network, all users are granted read-only access to the share. If you want to allow users to modify files in the share or allow them to create new files, you need to add permissions. Here’s how to do this using Windows Explorer: Open Windows Explorer by pressing the Windows key and clicking Computer; then browse to the folder whose permissions you want to manage.
User accounts are among the basic tools for managing a Windows server. As a network administrator, you’ll spend a large percentage of your time dealing with user accounts To create a new domain user account in Active Directory, follow these steps:Choose Start→ Windows Administrative Tools → Active Directory Users and Computers.
One of the most basic questions that a network plan must answer is whether the network will have one or more dedicated servers or rely completely on peer-to-peer networking. If the only reason for purchasing your network is to share a printer and exchange an occasional file, you may not need a dedicated server computer.
Managing a small computer network is well within your reach, but it's vital to track key information that's unique to your network. Begin by recording your network and Internet connection information in one place, making it easy to find and readily available when you need it. Then, get to know some of the basic networking concepts such as pin connections and IP address ranges — and become familiar with useful websites for networking information.
Firewalls employ four basic techniques to keep unwelcome visitors out of your network. The following article describes these basic firewall techniques. Packet filtering A packet-filtering firewall examines each packet that crosses the firewall and tests the packet according to a set of rules that you set up. If the packet passes the test, it’s allowed to pass.
As a network administrator, the Internet is your best friend for networking resources, solutions, news, and guidance. Here are some websites for you to visit often. To register domains: InterNIC Network Solutions register.com To check your TCP/IP configuration: DNSstuff To see if your email server has been blocklisted: DNSBL.
Although an occasional sacrifice to the Office gods may make your networking life a bit easier, a template isn’t a place of worship. Rather, a template is a special type of document file that holds formatting information, boilerplate text, and other customized settings that you can use as the basis for new documents.
What is networking and what components make up a network? A network is nothing more than two or more computers connected by a cable or by a wireless radio connection so that they can exchange information.Of course, computers can exchange information in ways other than networks. Most of us have used what computer nerds call the sneakernet.
