The History of Networking:
Founder of networking Bill robinson
What is a network on a computer?
A computer network or data network is a telecommunications network which allows computers to exchange data. In computer networks, networked computing devices exchange data with each other using a data link. The connections between nodes are established using either cable media or wireless media.
What is Business network?
Business networking is an effective low-cost marketing method for developing sales opportunities and contacts, based on referrals and introductions - either face-to-face at meetings and gatherings, or by other contact methods such as phone, email, and increasingly social and business networking websites.
What is a network in communication?
Defined by their size and complexity, they come in four main types: (1) small networks, used for the connection of subassemblies and usually contained in a single piece of equipment; (2) Local Area Networks, or LAN, cables or fibers used to connect computer equipment and other terminals distributed in a localized area.
What is a types of network
Common types of area networks are:
LAN - Local Area Network.
WAN - Wide Area Network.
WLAN - Wireless Local Area Network.
MAN - Metropolitan Area Network.
SAN - Storage Area Network, System Area Network, Server Area Network, or sometimes Small Area Network..
Use of networking between Two Home Computer for file sharing
The simplest kind of home network contains just two computers. You can use this kind of network to share files,
a printer or another peripheral device, and even an Internet connection. To connect two computers for sharing these
and other network resources, consider the options described below.
Connecting Two Computers Directly With Cable The traditional method to network two computers involves making a dedicated link by plugging one cable into the two systems.
Several alternatives exist for networking two computers in this manner:
Ethernet crossover cable Null modem serial cable or parallel peripheral cable Special-purpose USB cables
1. Ethernet: Ethernet method is the preferred choice as it supports a reliable, high-speed connection with minimal configuration required. Additionally, Ethernet technology offers the most general-purpose solution, allowing networks with more than two computers to be built fairly easily later. If one of your computers possesses an Ethernet adapter but the other has USB, an Ethernet crossover cable can still be used by first plugging a USB-to-Ethernet converter unit
into the computer's USB port.

2. Serial and parallel: This type of cabling, called Direct Cable Connection (DCC) when using Microsoft Windows,
offers lower performance but offers the same basic functionality as Ethernet cables.
You may prefer this option if you have such cables readily available and network speed is not a concern. Serial
and parallel cables are never used to network more than two computers.
3. USB: Ordinary USB cables must not be used to connect two computers directly to each other. Attempting to do so
can electrically damage the computers!
However, special USB cables designed for direct connection exist that can be used safely. You may prefer this option over others if your computers lack functional Ethernet network adapters.
To make dedicated connections with Ethernet, USB, serial or parallel cables requires that:
each computer has a functioning network interface with an external jack for the cable, and the network settings on each computer are appropriately configured One phone line or power cord cannot be used to directly connect two computers to each other for networking.
