Computer Network Fundamentals

Network Fundamentals

• The primary purpose of a VPN (Virtual Private Network) is to provide a secure and encrypted connection between a device and a network over the internet.

Network Devices

• The main difference between a hub and a switch is that a hub is a simple network device that broadcasts data to all connected devices, whereas a switch is a more advanced device that directs data to specific devices on the network.

IP Addressing

• The purpose of the subnet mask in a network is to determine the scope of a subnet, allowing devices to determine whether an IP address is on the same subnet or on a different subnet.

Network Types

• A network that spans a city or a town is referred to as a Metropolitan Area Network (MAN).

Domain Name System

• The purpose of the DNS (Domain Name System) is to translate human-readable domain names into IP addresses that computers can understand, allowing users to access websites and online resources using easy-to-remember domain names instead of IP addresses.
