i. Wireless Access Points:

Wireless Access Points (WAPs) are devices used in computer networks to provide wireless connectivity. They act as a central hub for wireless devices to connect to the network. WAPs receive and transmit wireless signals, allowing devices such as laptops, smartphones, and tablets to access the network without the need for physical cables. They typically connect to a wired network and extend the network's reach by providing wireless coverage in a specific area.

ii. Gateways:

Gateways are devices that connect different networks together. They act as an entry point or an exit point for data packets between networks. Gateways are responsible for routing data between networks with different protocols or network architectures. They can also perform protocol translation, allowing devices on one network to communicate with devices on another network. Gateways are commonly used in computer networks to connect local area networks (LANs) to wide area networks (WANs) or to connect different LANs together.

iii. Firewalls:

Firewalls are devices or software applications used to protect computer networks from unauthorized access and potential threats. They act as a barrier between the internal network and external networks, such as the internet. Firewalls monitor incoming and outgoing network traffic and apply security rules to allow or block specific types of traffic based on predefined policies. They can also perform tasks such as packet filtering, intrusion detection, and prevention, and network address translation. Firewalls are essential in maintaining network security and preventing unauthorized access to sensitive data.
