COMPUTER FUNDAMENTALS

Detailed explanation-1: -Packet switching is used for grouping data into packets for transmission over a digital network. It’s an efficient way to handle transmissions on a connectionless network, such as the internet. On the other hand, circuit-switched transmission is used for voice networks.

Detailed explanation-2: -Any data sent over the Internet is divided into smaller segments called packets.

Detailed explanation-3: -All data sent over the internet is broken down into several packets. Packets are the units of data that are sent over the network. Packets are labeled with metadata and each packet is sent individually with its own packet number. If they arrive out of order, the number allows them to be pieces back together.

Detailed explanation-4: -Each time one device sends a file to another, it breaks the file down into packets so that it can determine the most efficient route for sending the data across the network at that time. The network devices can then route the packets to the destination where the receiving device reassembles them for use.

Detailed explanation-5: -Packet switching is used in the Internet and most local area networks. The Internet is implemented by the Internet Protocol Suite using a variety of link layer technologies. For example, Ethernet and Frame Relay are common. Newer mobile phone technologies (e.g., GSM, LTE) also use packet switching.
