Networks and the effects of using them (chapter 4)

Network Interface Card (NIC)

A hardware component that allows a device to connect to a network by converting binary data into electrical signals.

MAC Address

A unique 48-bit identifier assigned to each NIC, used to identify devices on a network.

Internet Protocol (IP) Address

A numerical label assigned to each device connected to a network that identifies its location.

Data Packets

Units of data transmitted over a network, which include a header with information about the sender and receiver.

Hub

A networking device that connects multiple devices in a LAN and broadcasts data packets to all connected devices.

Switch

An intelligent device that connects devices in a LAN and directs data packets only to the intended recipient.

Bridge

A device that connects two or more LANs using the same protocol to function as a single network.

Router

A device that routes data packets between different networks based on their IP addresses.

Wi-Fi

A technology that allows devices to communicate wirelessly over a network, typically covering larger distances than Bluetooth.

Bluetooth

A wireless technology for short-range communication between devices, usually less than 30 meters.

Cloud Storage

A service that allows data to be stored on remote servers accessed via the internet.

Local Area Network (LAN)

A private network within a single location, connecting multiple devices to share resources.

Wireless Local Area Network (WLAN)

A LAN that uses wireless communication, providing mobility and easier access but often with security and speed drawbacks.
