basic introduction about networking and its components.
Network:
Network is connected collection of devices (computer, routers, switches and interconnections)that communicates with each other by providing the means for users to share hardware and applications.
LAN:
LAN Stands for Local Area Network. LAN is a network that is located in limited area with the computers and other components, that are part of this network, located relatively closed together.
Ethernet Switches:
Ethernet switches divides the collision domains and reduce the number of devices that are competing for bandwidth.
Ethernet switches selectively forward individual frames from a receiving port to the destination port.
Optical Fiber:
Optical fiber permits transmission over longer distances and higher data rates.
Switch:
Switch creates and maintains MAC address table by using the source MAC address of incoming frames and port number through which the frames entered the switch.
Components of Network:
1) Endpoints: Send and receive data.
2) Interconnections : Transmission of data from one point to another point.
3) Switch : Provide data within local network.
4) Router : Interconnects network and choose the best paths between networks.
Characteristics of Network:
1) Topology
a) Physical Topology
Physical topology describes the layout for wiring the physical devices.
i) Bus Topology
ii) Star Topology
iii) Mesh Topology
b) Logical Topology
4) Security : Protection of the information transferred over internet.
5) Availability : Network will be available for use of 24/7.
6) Scalability : How easily the network can accommodate more users and data transmission requirements.
7) Reliability : Measured as probability of failure.

Logical topology describes how information flows through a network.
2) Speed : Measures of the data rates in bits per second of a given link in the network.
3) Cost : Indicates the expenses for purchasing network components.2) Speed : Measures of the data rates in bits per second of a given link in the network.
