COMPUTER NETWORKING EXAM 2
QUESTIONS AND ANSWERS
What are the similarities between the OSI and TCP/IP models? - Answer-Both use
layers in their protocols
What are differences between the OSI and TCP/IP models? - Answer-OSI has more
layers (Session and Presentation)
OSI is a more reliable network protocol system
How many bits are IP addresses? - Answer-32-bit sequence
What is the difference between Public and Private IP addresses? - Answer-Public IP
address are able to connect to the internet, you can have a multitude of private IP
address using the same Public IP address.
Explain IPv6 - Answer-Next generation IP addressing system
128-bit addresses
This means that there are more combinations of IP addresses available meaning that
this will last for a long time
Explain UDP - Answer-Connectionless and unreliable
What is the purpose of ARP and RARP? - Answer-Address Resolution Protocol and
Reverse Address Resolution Protocol
Goal is to obtain MAC and IP addresses
IP - Answer-Connectionless communication
Provides best effort delivery
TCP - Answer-Reliable and connection orientated
UDP - Answer-Unreliable and connectionless
What is TCP/IP? - Answer-Transmission Control Program / Internet Protocol is one of
the most popular networking protocols ever developed. Used to connect the largest
computer network, the internet.
How many layers are there in TCP/IP protocol? - Answer-5 Layers
1. - Physical
2. - Network Interface
3. - Internet
4. - Transport
5. - Application
