Network
Interconnected collection of computers and communication devices
Node
Individual computer or device connected to a network
Host
Computer or device connected to a network that provides services
Advantages of Networking
Sharing equipment and data
,Disadvantages of Networking
Personnel and cost increase, vulnerabilities to cyberattacks
Local Area Network (LAN)
A network that is usually confined to a single building and managed by a single
entity. Example: Office Building
Metropolitan Area Network (MAN)
Consists of two or more LANs connected with private or public communication
lined within the same geographic area—for example, a computer network used by
governmental employees of an entire city.
Wide Area Network (WAN)
Consists of a large number of networks and PCs connected with private and public
communication lines throughout many geographic areas; for example, computers
used by the US government.
Personal Area Network (PAN)
A small network, perhaps consisting of a single computer and mobile device.
, Campus Area Network (CAN)
A network spread across multiple buildings in the same geographical location,
much like a college campus.
Global Area Network (GAN)
Any network that spans multiple countries, for example, the Internet.
Star Topology
A topology that involves running cables from each node to connect a single point.
The center is usually a device known as a hub.
Ring Topology

Bus Topology
Network topology that uses a single cable or conductor to connect all nodes on
the network.
Mesh Topology
