Objective 2.2: Networking Hardware
This objective focuses on comparing and contrasting common networking hardware devices. Here are the key components you need to know:

Network Interface Card (NIC):
A hardware component that allows computers to connect to a network.
Can be wired (Ethernet) or wireless (Wi-Fi).
Essential for network communication.

Router:
A device that forwards data packets between computer networks.
Operates at the network layer (Layer 3) of the OSI model.
Connects different IP subnets and directs traffic based on IP addresses.

Switch:
A device that connects multiple devices within a single network.
Operates at the data link layer (Layer 2) of the OSI model.
Uses MAC addresses to forward data to the correct destination.

Access Point (AP):
A device that allows wireless devices to connect to a wired network.
Extends the range of a wireless network.
Often used in conjunction with routers.

Modem:
A device that modulates and demodulates signals for data transmission over telephone lines or cable systems.
Converts digital data from a computer to analog signals for transmission and vice versa.

Firewall:
A network security device that monitors and controls incoming and outgoing network traffic.
Can be hardware-based or software-based.
Protects networks from unauthorized access and cyber threats.
