Question 1 Differentiate between two transport layer protocols TCP and UDP. Give an example of application protocol working with TCP in transport layer and an application working with UPD in transport layer.
TCP (Transport Control Protocol) is a transport layer protocol that provides full duplex, connection-oriented, and trustworthy transport layer delivery services. What do we mean by "connection-oriented," "reliable delivery," and "full duplex"? What exactly do we mean by connection-oriented, dependable delivery, and full duplex?
The Transport Control Protocol (TCP) is a transport layer protocol that provides full duplex, connection-oriented, and reliable delivery services. When we say connection-oriented, reliable delivery, and full duplex, what exactly do we mean? What are connection-oriented, dependable delivery, and full duplex mean?
The Transport Control Protocol (TCP) is a protocol that operates at the transport layer and provides full duplex, connection-oriented, and reliable delivery services. When we talk about full duplex, reliable delivery, and a focus on connections, what do we mean? Definitions of "connection-oriented," "reliable delivery," and "full duplex"
Consider the pros and cons of connectionless protocols as a potential substitute for connection-based protocols in a brief overview
The two main protocols that work at the transport layer are TCP and UDP. Please explain why TCP rather than UDP might be used in the development of a certain application. Give two (2) cases, each distinct.
Q: Describe in detail how TCP packets flow in the case of TCP handoff, along with the information on source and destination addresses in the various head- ers.
Two transport-layer protocols may be used by certain application applications (UDP or TCP). How does a computer determine which transport layer is engaged after a packet has arrived at its destination?
Question 1: True or False: [ ] Telephone network is an example of Packet Switching network. [ ] It is the network layer’s responsibility to forward packets reliably from the source to the destination [ ] Flow control is required to assure that the source does not overwhelm the destination by sending data faster than they can be processed and absorbed. [ ] The key elements of a Protocol are syntax, semantics, and error control [ ] User Datagram Protocol (UDP) can guarantee data delivery. [ ] Routing decision is always required for every packet of a message at each node in packet switched network. [ ] In OSI model data link layer provides for the reliable transfer of information across the physical link; sends blocks (frames) with the necessary synchronization, error control, and flow control. [ ] The transport layer is responsible for hop-by-hop communication. [ ] Because the boundaries between layer are well defined change in standard in one layer effect already existing…
