Packetization is the process of breaking down data into smaller units called packets for transmission over an IP network. This process involves dividing the data into manageable chunks and adding necessary header information to each packet. Packetization involves segmenting data, adding headers to each segment or fragment, and encapsulating them into packets for transmission over…

Routing is a fundamental concept in computer networking that involves the process of directing network traffic between different networks or subnets. It determines the most efficient path for data packets to travel from a source device to a destination device across an interconnected network infrastructure. The device responsible for making routing decisions is called a…

Network encryption is a security measure that involves the conversion of data transmitted over a computer network into an unreadable format. This process helps protect the confidentiality and integrity of sensitive information while it is being transmitted across a network, such as the internet or a local area network (LAN). Encryption ensures that even if…
