Introduction to IP Address

An example of a home network involves using a router to connect various devices, such as laptops, phones, and smart TVs. In contrast, offices often utilize switches to connect multiple computers and printers within a Local Area Network (LAN), facilitating efficient resource sharing and communication.

IP Addressing Fundamentals

An IP address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. Each IP address serves two main functions: identifying the host or network interface and providing the location of the host in the network.
