23- Which layer are called upper layer?
a ) Application Layer    – 7
b) Presentation Layer   – 6
c ) Session Layer            – 5

24- How many reserve ports ?
0 – 1023

25- Which decision called socket base?
IP plus port (IP on layer 3 and port on Layer 4 – In Encapsulation, socket base decision on Network Layer -Layer 3)

26- How many types of Data?
Voice, video, text

27 What is segmentation and fragmentation?

To divide data in pieces is called segmentation and divide segmentation in pieces called Fragmentation.

28- Which layer called error detection layer ?
Data link layer

11- What is the difference between bus topology and HUB?

Hub is Centralized device ( series ) .Bus topology is Decentralized device (in parallel)

12- Is hub intelligent device?
No; because it not use header

12- Which protocol switch use for filling its MAC-Table ?
ARP – Address Resolution Protocol

13- What is CAM ?
Content Address Memory. its another name of MAC address table.

14- Which type for communication switch do?
In case of any new event switch do broadcast, after that always do Unicast.

15- If line down and protocol also down; in this case which layer move problem?
Physical Layer – Layer 1

16 – If line up, but protocol down which layer should be troubleshot?
Data link problem – Layer 2

17-On which base switches take decisions?
Mac Address

18- How ARP brings MAC address for switch?
Through Broadcast

19- How many collision domains are in switch?
Equal number of ports

20- How many broadcast domains are in Switch ?
One

1- Define Network?

Communication, Resource sharing and Media (When multiple host share their resources with each other OR when multiple devices connect with each other for resource sharing )

2 – Types of communication in IPv4?
Unicast, Multicast and Broad cast

3 – Types of communication in IPv6 ?
Unicast, Multicast and Anycast

4- Types of Resource Sharing?
Intranet , Extranet and Internet .

5- What is Collision?
When signal hits each other, collision accord.

6- Which Type of Transmission Bus Topology Support?
Half Duplex

7- What is the difference between half duplex and full duplex?
In half duplex, sender should b one. In full duplex, sender can be multiple.

8- Which way of communication bus topology use?
Broadcast

9- If there is only 2 Host in Bus Topology is that possible collision accord?
Yes, because end terminal will not absorb signals. Signal will be bounce back and collision will accord.

10- HUB in Star topology or Bus Topology?
In star topology, but logically works like a bus topology.
