A network is a group of computers, printers and other devices which can be connected together with cables. Information travels over the wires, allowing network users to exchange documents & data with one another, print to the same models, and generally share any hardware or software that may be connected to the network.
Every computer, printer, or other peripheral device that may be connected to the network is named as a node. Networks can possess tens, thousands, or even a lot of nodes. Today, you can also search online to know more about networking basics and you can also find network virtualization at https://www.scalable-networks.com/.
The two most widely used types of network cabling are twisted-pair (also called 10BaseT) and thin coax (also called 10Base2). 10BaseT cabling looks similar to ordinary telephone wire, except who’s has 8 wires inside instead of 4. Thin coax looks much like the copper coaxial cabling that’s often employed to connect a VCR to a TV set.
A network computer is connected to the network cabling with a network interface card, (also called a “NIC”, “nick”, or network adapter). Some NICs are installed inside a computer: the PC is opened up and also a network card is plugged directly into on the list of computer’s internal expansion slots. 286, 386, and a lot of 486 computers have 16-bit slot machines, so a 16-bit NIC should be used.Networking Basics That You Should Know by Pat Mitchell
