Topologies and Protocol Suites (PART 2)

Q1. How many stations can be connected to 10Base2, 10BaseT, and 10Base5?

• 10Base2: 30
• 10BaseT: 1024 stations per network
• 10Base5: 100 nodes per segment and maximum network length of 10Base5 is five segments i.e. approximately 2500 meter

Q2. What is the maximum network length of 10Base2 and 10Base5?

• The maximum network length of 10Base2 is 185 m for each segment and can be extended up to five segments
•  The maximum network length of 10Base5 is 500 m for each segment and can be extended up to five segments

Q3. What is Fiber Distributed Data Interface (FDDI)?

• FDDI is token-passing dual ring fiber optic LAN specification. It supports higher transmission speeds across larger distances of around 2 km (1.3 miles) between two stations.

Q4. What is network binding?

• A network binding binds a protocol to an adapter to carry traffic using that protocol.

Q5.  What is NetBIOS Extended User Interface(NetBEUI) and is it routable?

• NetBEUI is designed for peer-to-peer network and is a high speed protocol used on small networks. It provides a good recovery and error protection.
• No, its not routable

Q6. Where is IPX/SPX used?

• IPX/SPX stands for inter-network packet Exchange/Sequenced packet Exchange. It is used in the Netware environment. IPX tuns at the network layer of the Open System Interconnection (OSI) model; whereas, SPX runs at the transport layer of the OSI model.

Q7.  What is NetBIOS?

• NetBIOS stands for Network Basic Input/Output System. It ia an application interface, which operates at the session layer. It enables communication between application with NetBIOS compliant protocol. NetBIOS applications can be supported over Transmission Control Protocol/Internet Protocol (TCp/IP) and IPX/SPX

 

Q8. What is the role of Internet Protocol (IP)?

• IP provides connectionless delivery between computer systems. It does not guarantee the delivery of the packets.

Q9. What is the role of Transmission Control Protocol (TCP) ?

• TCP provides acknowledged and connection oriented communication. It provides guaranteed delivery with proper sequencing of packets and data integrity checks.

 

Q10. What is the role of User Datagram Protocol (UDP)?

• UDP is designed for connectionless unacknowledged communications. It adds the information about the source and destination socket identifiers in the datagrams; however, it provides and unreliable service and datagrams may arrive out of order, or appear duplicated.

 

Q11. What is the role of Address Resolution Protocol (ARP)?

• ARP restored IP Addresses to Media Access Control (MAC) addresses. Physical frames have to be addressed to hardware MAC address of destination network deice
