MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Each device connected to a network requires a unique IP address. At home, dynamic host configuration protocol (DHCP) assigns IP addresses to your smartphones, laptops, tablets, and devices like doorbell cameras. When you use wifi on your home network, typically your router is a DHCP server.

Detailed explanation-2: -One of the primary jobs of a router is to assign IP addresses to the computers on a home network. The router has a “pool” of IP addresses that it keeps track of. When a computer connects to it and asks for an IP address, the router picks an IP address from the pool and assigns it to the computer.

Detailed explanation-3: -Your IP address is assigned to your device by your ISP. Your internet activity goes through the ISP, and they route it back to you, using your IP address. Since they are giving you access to the internet, it is their role to assign an IP address to your device.

Detailed explanation-4: -Dynamic IP addresses are assigned by network using Dynamic Host Configuration Protocol (DHCP). DHCP is the most frequently used technology for assigning addresses. It avoids the administrative burden of assigning specific static addresses to each device on a network.

Detailed explanation-5: -To see all of the devices connected to your network, type arp-a in a Command Prompt window. This will show you the allocated IP addresses and the MAC addresses of all connected devices.
