3. The process of HTTP asking TCP to send some data and making sure that it is received
correctly is an example of what?
a. Same-layer interaction
b. Adjacent-layer interaction

1st ka D & F aur 2nd ka C & G hoga tanuj sir i guess..but correct me if i'm wrong
ReplyDelete2nd ka you said ip is correct but ip protocol lies in internet layer not on network layer i think.
Delete1st mein to G option hi nahi hai its my mistake i mean last option

3. B. Adjacent-layer interaction occurs on one computer, with two adjacent layers in the
model. The higher layer requests services from the next lower layer, and the lower
layer provides the services to the next higher layer.
4. B. Same-layer interaction occurs on multiple computers. The functions defined by
that layer typically need to be accomplished by multiple computers—for example, the
sender setting a sequence number for a segment, and the receiver acknowledging
receipt of that segment. A single layer defines that process, but the implementation of
that layer on multiple devices is required to accomplish the function.
5. A. Encapsulation is defined as the process of adding a header in front of data supplied
by a higher layer (and possibly adding a trailer as well).
