Internet protocol address
The email server runs email server software. Clients use mail client software, such as Microsoft outlook, to access on the server.
Client and server software usually run on separate computers, but it is also possible for one computer to be used for both roles at the same time.
In small businesses and homes, many computers function as the servers and clients on the network. This type of network is called a peer-to-peer network.

The network devices that people are most familiar with are end devices. To distinguish one end device from another, each end device on a network has an address
End Devices
. They can connect multiple individual networks to form an internetwork
Intermediary Devices
Intermediary network devices perform some or all of these functions:
Regereate and retransmit communication signals
Maintain information about what pathways exist through the network and internetwork
Notify other devices of errors and communication failures
Direct data along alternative pathways when there is a link failure
Classify and direct messages according to priorities
Permit or deny the flow of data, based on security settings
Network Media
Communication transmits across a network on media. The media provides the channel over which the message travels from source to destination
Data is encoded into electrical impulses.
Metal wires within cables
Data is encoded into pulses of light.
Glass or plastic fibers within cables (fiber-optic cable)
Data is encoded via modulation of specific frequencies of electromagnetic waves.
Wireless transmission
Network architects and administrators must be able to show what their networks will look like.
Network Representation
A NIC physically connects the end device to the network.
