(Windows 11) What you need to Set Up a Home and Business Network of Computers

There are several kinds of hardware used in Computer Networks, lets lists and read definitions, and different technologies along the way.

Network Interface Cards or NICs connect computers to a network so that they can communicate. NIC can be connected to the USB or Ethernet port on your computer or installed inside your computer in an available Peripheral Component Interconnect (PCI) expansion slot.

Network hubs and switches. Hubs and switches connect two or more computers to an Ethernet network. Its the central device that connects all the devices together. A switch costs a little more than a hub, but it's faster.

Routers and access points. Routers connect computers and networks to each other (for example, a router can connect your home network to the Internet). Routers also enable you to share a single Internet connection among several computers. Routers can be wired or wireless. You don't need to use a router for a wired network but we recommend it if you want to share an Internet connection. If you want to share an Internet connection over a wireless network, you will need a wireless router. Access points allow computers and devices to connect to a wireless network.

Network cables (Ethernet, HomePNA, and Powerline). Network cables connect computers to each other and to other related hardware, such as hubs, routers, and external network adapters. HomePNA and Powerline adapters are often external and connect to a computer with either Ethernet cables or USB cables, depending on the type of adapter.

You might decide to go with a certain technology because you already have most of the hardware, or you might decide to upgrade your hardware. A combination of technologies might work best for your environment. For example, many people use a wireless router, which accommodates both wired Ethernet connections for desktop computers and wireless connections for laptops.
