Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Which model has 4 layers?

A	UCP/UP
B	TCP/IP
C	CS/IP
D	UDP/IP

Explanation:

Detailed explanation-1: -There are four layers of the TCP/IP model: network access, internet, transport, and application. Used together, these layers are a suite of protocols. The TCP/IP model passes data through these layers in a particular order when a user sends information, and then again in reverse order when the data is received.

Detailed explanation-2: -Additionally, the bottom two layers-Physical and Data Link-are combined into the Network Access layer for TCP/IP. Therefore, there are 4 layers in the TCP/IP Model.

Detailed explanation-3: -Layer 4 of the OSI Model: Transport Layer provides transparent transfer of data between end users, providing reliable data transfer services to the upper layers. The transport layer controls the reliability of a given link through flow control, segmentation and desegmentation, and error control.

Detailed explanation-4: -The TCP/IP model consists of five layers: the application layer, transport layer, network layer, data link layer and physical layer.
