Computer Networks Basics

Advantages of networks

• File Sharing: Users can easily share files and data.

• Resource Sharing: Devices like printers and internet connections can be shared.

• Improved Performance: Networks can enhance the speed of individual devices.

• Centralised Backup: Data can be backed up on a central server.

Star topology

• A network design where all devices are connected to a central switch.

• A network design where each device is connected to every other device directly.

• A network design that uses a single cable to connect all devices in a line.

• A network design that connects devices in a circular manner.

Bluetooth

• A wireless connection method similar to wi-fi but has a shorter range. Range: about 15m
