Test: Introduction & IP Addressing- 2 - Computer Science Engineering (CSE) MCQ

Maximum 4 repeaters can be placed in one transmission path between two nodes while 5 between two nodes.

Number of host in class A = 2²⁴ - 2 Number of host in class B = 2¹⁶ - 2 Number of host in class C = 2⁸ - 2 Number of host in class D = 0

A repeater takes a weak or corrupted signal and regenerate it

Default subnet mask of class A network 11111111-00000000-00000000-00000000 
⇒ 255-0-0-0.

Router is used to connect two different class networks.

Number of hosts in class A = 2²⁴ - 2 Number of hosts in class B = 2¹⁶ - 2 Number of hosts in class C = 2⁸ - 2

The effective data burst is a measure of average data rate, peak data rate and maximum data rate.

Physical address is also known as MAC address. Logical address is also known as IP address COM1 is a communication port.

In IP add re sse s class A, B, and C used for general purpose.

If IP address is AND with subnet mask result will network address.
Default subnet mask:
Class A = 255.0.0.0
Class B = 255.255.0.0
Class C = 255.255.255.0

Packet switching→ network iayer.
Route determination→ 4 network layer.
Flow control → datalink and transport layer.

• Reassembly of packets is done at transport iayer.
• Responsibility for delivery between adjacent nodes is of data link layer.
• Mechanical electrical and functional interface is related to physical layer. 
•  Error correction and retransmission is done at data link layer as well as transport layer. 

Subnet mask

6 bit are used for subnetting.
So number of possible subnets - 2⁶ = 64.
