Answer the following questions briefly.T 1. How does resource reservation work in the TCP/IP model? 2. Which TCP/IP layer is responsible to reserve resources across a network using the TCP/IP model? 3. What protocol assigns an IP address to the elient connected to the Internet?

Transmission Control Protocol / Internet Protocol (TCP / IP) is a suite of communication protocols used to connect network devices on the Internet. TCP / IP can also be used as a communication protocol on a private computer network e.g., an intranet or extranet TCP defines how applications can create communication channels over a network. It also manages how a message is divided into smaller packets before they are transmitted over the Internet and reassembled in the correct order at the destination address. IP Address defines how each packet is routed and forwarded to ensure that it reaches the correct destination. Each gateway computer on the network checks this IP address to determine where to route the message. TCP / IP uses the client-server communication model, in which a user or computer (a client) receives a service (such as sending a web page) from another computer (a server) on the In short, the TCP / IP protocol suite is classified as stateless, which means that each client request is considered new because it has nothing to do with previous requests. Being stateless, network routes are released so that they can be used continuously. Answer the following questions briefly. 1. How does resource reservation work in the TCP / IP model? 2. Which TCP / IP layer is responsible to reserve resources across a network using the TCP / IP model? 3. What protocol assigns an IP address to the client connected to the Internet? 4. Checksum is used by various protocols on the Internet, but not at the one of TCP / IP layers. Explain.
