Computer Networking Guide

In the world of computers, networking refers to the linking of two or more computers together for the purpose of sharing data.  Networks are built with a variety of computer hardware and software components.  Read on to learn more!  

At a Glance

  • Area Networks:  This defines the type of network by the geographic area that it spans.  Local Area Networks  (LANs), for example, range through one home; Wide Area Networks  (WANs) reach across cities, states, and countries.  The Internet is the world's largest WAN.   
  • Network Design:  There are two types of network design: client-server and peer-to-peer.  
    • Client-server networks  feature centralized server computers that store email, web pages, files and/or applications.  They are most commonly used in business.
    • On a peer-to-peer network , all computers tend to support the same functions.  These are typically used to create networks in the home. 
  • Network Protocol:  In networking, the protocols refer to the communications used by computer devices; another way to classify networks is by the set of protocols that they support.  Networks often implement multiple protocols to support specific applications. Popular protocols include TCP/IP , the most common protocol found on the Internet and in home networks.
  • Network Routers:   These are the physical devices that join multiple wired or wireless networks together.  Home networkers often use an Internet Protocol  (IP) wired or wireless router .  An IP router such as a DSL or cable broadband router  joins the home's local area network (LAN) to the wide-area network (WAN) of the Internet.
  • Network Servers:  The network server  refers to the computer designed to process requests and deliver data to the other computers over a network.  Network servers typically are configured with additional processing, memory and storage capacity to handle the load of servicing users.
  • Wired vs. Wireless Networks:  Many of the same network protocols, like TCP/IP, work in both wired  and wireless networks . Networks with Ethernet cables  predominated in businesses, schools, and homes for quite some time; yet recently, wireless networking alternatives  have emerged as the premier technology for building new computer networks.
