1. First, you will need to log on with administrator privileges in order to set up a network. This requirement prevents unauthorized users from changing network settings. There should be only one administrator account on the network, and its username and password should be closely guarded secrets.

2.You will need some hardware to physically connect the computers. There are several options available, but the fastest and most reliable is Ethernet cabling. Wireless connectivity is more convenient because you don’t have cables running everywhere, but it is slower than 100 Mbps Ethernet and can be subject to interference. Nonetheless, wireless networking is a popular choice in small offices. Other technologies use phone or power lines to connect computers

3.Each technology will have its own kind of NIC (network interface card), a device that plugs into a computer and enables it to communicate with the network. These devices can take various forms. A PCI (peripheral component interconnect) card requires you to open up the computer to install it. A USB form factor just plugs into a USB port. A laptop computer will have a PC Card port. An Ethernet card will have ports for cables, while a wireless card may have a stubby antenna

4.
Software drivers provided with NICs configure the hardware you install for use with the network. This configuration is usually done automatically by Windows when it detects a newly installed device.

5.device that routes traffic come together at one between the All of the computer connections appropriate machines. This device can be a simple hub or switch, but more often it is a router that also handles sharing an Internet connection. In the case of a wireless network, a device called an access point broadcasts radio signals to all of the NICs. Often a router is built into the access point to enable Internet sharing.It is usually preferable to use a router instead of a hub or switch when sharing an Internet connection. Otherwise, the Internet will not
