What is a Network?
Before I go deeper into the different Networking Jobs you need to know the basics what a Network entails.
What do you think about when you here the terms Networking concepts? (Think about your social network and how do you communicate with this social network).
If we now take a look at an IT Network the concept is largely the same.
A LAN is your Local Area Network: This can be your home network or your small office network where every device is connected to each other via WIFI or Cable or both.
A WAN is a Wide Area Network that connects each LAN and makes sure that communication is possible between each LAN.
(The connection in between LAN’s is provided by your ISP or in other words your internet provider)
Computer networks allow users to share and communicate resources. Can you imagine a world without emails, online newspapers, blogs, websites and the other services that the Internet provides? Networks also allow users to share resources such as printers, applications, files, folders, and storage drives.
Example of a small Network
What is a switch?
A switch is a device for making multiple connections from one connection, without losing speed.
There are different types of switches, such as managed and unmanaged. The difference is in the presence of options for managing the network in the device. A managed switch is equipped with software that can be used to control the management.
The switch is connected to the router that will lead us outside.
What is a router?
With a router you can connect multiple computer networks, this ensures that there is also communication between these different networks.
