TRANSPORT LAYER

INTRODUCTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which transport layer protocol ensures reliable same-order delivery?
A
ICMP
B
IP
C
TCP
D
UDP
Explanation: 

Detailed explanation-1: -TCP provides reliable stream delivery of data between Internet hosts. Like UDP, TCP uses Internet Protocol, the underlying protocol, to transport datagrams, and supports the block transmission of a continuous stream of datagrams between process ports. Unlike UDP, TCP provides reliable message delivery.

Detailed explanation-2: -Transport layer protocols at this level are Transmission Control Protocol (TCP), User Datagram Protocol (UDP), and Stream Control Transmission Protocol (SCTP). TCP and SCTP provide reliable, end-to-end service. UDP provides unreliable datagram service.

Detailed explanation-3: -TCP is therefore considered a “reliable, connection-oriented” protocol.

Detailed explanation-4: -The transport layer provides a total end-to-end solution for reliable communications. TCP/IP relies on the transport layer to effectively control communications between two hosts.
