Type of Network
- Local Area Network is used for small geographical area. For example home, schools, and office building. It allows file exchange, emails, printer sharing and accessing the Internet.
- Metropolitan Area Network to serve metropolitan area.
- Wide Area Network is a network that serves large geographical area. This network allows people especially who involves in business to communicate and carry on activities no matter how far their locations.
- Above networks are depending on the geographical area.
Network Component
- Host/End Nodes - data source
- Transmission Media - to transmit data and controls signal.There are two types of transmission media, bounded and unbounded. Bounded (wired) has twisted pair wire, coaxial cable and fiber optic cable.
- Unbounded (wireless)
- Network Electronic Device - control data from source to destination. It also connect multiple network or connect computer or network to the internet.

- Applications/Software - The applications involves technique and protocols. Protocols discover the rules and procedure to send data, terminate data, interpret data, present data and control mistakes. It ensure data is delivered at its destination. It also control data transmission.
- Network Architecture Standard & Protocol - It covers how device in a network typically correct and how the device communicate. It also enable devices to communicate to each other.
- Network architecture consists of two types, client/server networks and peer to peer networks.
Network Topology
- the arrangement or mapping of the elements of a network. There are two types of network topology, physical and logical.
- Logical Network Topology
