This document provides information about computer networking. It defines what a network is and gives examples like mail systems, phone systems, and transportation networks. It then discusses different types of computer networks like LAN, WAN, MAN, SAN, and PAN. It also covers network design including client-server and peer-to-peer networks. Finally, it mentions some common network protocols like TCP/IP and discusses wired versus wireless networking.

3. A network is a way to get “stuff” between 2 or more “things” Examples: Mail, phone system, conversations, railroad system, highways and roads. In the world of computers, networking is the practice of linking two or more computing devices together for the purpose of sharing data. Networks are built with a mix of computer hardware and computer software. What is a “Network”?

LAN - Local Area Network WLAN - Wireless Local Area Network WAN - Wide Area Network MAN - Metropolitan Area Network SAN - Storage Area Network, System Area Network, Server Area Network, or sometimes Small Area Network CAN - Campus Area Network, Controller Area Network, or sometimes Cluster Area Network PAN - Personal Area Network DAN - Desk Area Network Types of networking

6. Networks can be categorized in several different ways. One approach defines the type of network according to the geographic area it spans. Local area networks (LANs), for example, typically reach across a single home, whereas wide area networks (WANs), reach across cities, states, or even across the world. The Internet is the world's largest public WAN. Area Networks

7. Computer networks also differ in their design. The two types of high-level network design are calledclient-server and peer-to-peer. Client-server networks feature centralized server computers that store email, Web pages, files and or applications. On a peer-to-peer network, conversely, all computers tend to support the same functions. Client-server networks are much more common in business and peer-to-peer networks much more common in homes. A network topology represents its layout or structure from the point of view of data flow. In so-called bus networks, for example, all of the computers share and communicate across one common conduit, whereas in a star network, all data flows through one centralized device. Common types of network topologies include bus, star, ring and mesh. Network Design

8. In networking, the communication language used by computer devices is called theprotocol. Yet another way to classify computer networks is by the set of protocols 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 Protocols

9. 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 several decades. Recently, however, wireless networking alternatives have emerged as the premier technology for building new computer networks. Wired vs Wireless Networking
