Study Notes
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.
