Frequently Asked Questions
What is a LAN?
A LAN, or local area network, is a computer network that connects devices within a limited geographic area, such as a home, office, or campus. LANs are typically faster and more reliable than other types of networks because they cover a smaller area and are often managed by a single organization.
What is a router?
A router is a networking device that connects multiple networks together and directs traffic between them. Routers use routing tables and protocols to determine the best path for data to take between devices on different networks.
What is a firewall?
A firewall is a security device that is used to control access to a network by monitoring and blocking incoming and outgoing network traffic. Firewalls can be hardware or software-based and are often used to protect networks from unauthorized access and attacks.
What is Wi-Fi?
Wi-Fi is a wireless networking technology that uses radio waves to transmit data between devices. Wi-Fi is commonly used in homes, offices, and public spaces to provide wireless internet access.
What is a protocol?
A protocol is a set of rules and procedures that govern the communication between devices on a network. Protocols define the format and meaning of messages exchanged between devices, as well as the actions that devices should take in response to those messages. Some common network protocols include TCP/IP, HTTP, and DNS.
