NETWORKING & WiFi SYSTEMS

COMPUTER NETWORKING

Computer networking is simply a group of computers that are connected to each other in some way (eg. wired (LAN), wireless or internet) for the purpose of communicating to each other.

Computer networking has existed for about 50 years, with the first network developed in the 1960s.

Since then, communication via computer networks has sky-rocketed and there are a wide number of connection methods.  California Communications specializes in Wired and Wireless LANs.

 

TYPES OF COMPUTER NETWORKS

Below is a list of some of the computer networks:

  1. Personal Area Network (PAN) is a computer network used by computer devices to typically one person. The distance is usually only a few meters.

  2. Local Area Network (LAN) is the most used computer network, and is typically a computer network covering a small area, such as a home, or business. These typically come in wired form (Ethernet) or wireless.

  3. Campus Area Network (CAN) is just a larger collection of Local Area Networks that are joined together. These usually just cover a limited geographical area and are often used in academic settings such as Schools or Universities.

  4. Wide Area Network (WAN) is a computer network that covers a broad area, such as regional or national boundaries.

  5. Virtual Private Network (VPN) is a computer network in which some of the links are carried by open connection to some other larger network (eg. the internet).

  6. Internetwork is the connection of two or more distinct computer networks or networking segments. These typically use the Internet Protocol, and examples of the interconnected networks are the Internet, Extranet and Intranet.
