Using a computer networks to perform an application, many pieces come together to assist in the operation. A network architecture or communication model places the appropriate network pieces in layers. i. List the TCP/ IP protocol suite layer(s) that performs each of the following functions: a.

Q.1.1 Using a
to assist in the operation. A network architecture or communication model places
the appropriate network pieces in layers.
i. List the TCP/ IP protocol suite layer(s) that performs each of the following
functions:
a. Data compression;
b. Multiplexing;
c. Routing;
d. Definition of a signal’s electrical characteristics.
ii. The layers of the TCP/ IP protocol suite and OSI are different. Which layers
are “missing” from the TCP/ IP suite? Are they really missing?
iii. If the data link layer provides error checking, and the transport layer provides
error checking, is this not redundant? Explain your answer.
iv. Similarly, the data‐link layer provides flow control, and the transport layer
provides flow control. Are these different forms of flow control? Explain your
answer.
