What is Networking?
What is a network anyway?
A network is just a collection of devices and end systems connected to each other and able to communicate with each other. These could be computers, servers, smartphones, routers, etc. A network could be as large as the internet or as small as your two computers at home
Sharing files and a printer.
Some of the components that make up a network:
Personal Computers (PC): These are the endpoint of your network, sending and receiving data.
Interconnections: These are components that make sure data can travel from one device to another, you need to think about:
Network Cards: they translate data from your computer in a readable format for the network.
Media: network cables, perhaps wireless.
Connectors: the plug you plug in your network card.
Switches: These boxes are network devices that provide a network connection for your end devices like PCs.
Routers: Routers interconnect networks and choose the best path to each network Destination.
TYPES of APPLICATIONS
File transfers like FTP, TFTP, perhaps an HTTP download. Could be a backup at night.
No direct human interaction.
High bandwidth is important but not critical.
Someone is waiting for a response, so response time (delay) is important
Also Human-to-Human interaction
VoIP (Voice over IP) or live video conferencing.
End-to-end delay is critical
