What is DNS ?

DNS is Domain Name Server. The main function of this network service is to provide host names to TCP/IP address resolution.

What advantages does fiber optics have over other media ?

One major advantage of fiber optics is that is it less susceptible to electrical interference. It also supports higher bandwidth, meaning more data can be transmitted and received. Signal degrading is also very minimal over long distances.

What is the difference between a hub and a switch ?

A hub acts as a multiport repeater. However, as more and more devices connect to it, it would not be able to efficiently manage the volume of traffic that passes through it. A switch provides a better alternative that can improve the performance especially when high traffic volume is expected across all ports.

What are the different network protocols that are supported by Windows RRAS services ?

There are three main network protocols supported: NetBEUI, TCP/IP, and IPX.

What are the maximum networks and hosts in a class A, B and C network ?

  • For Class A, there are 126 possible networks and 16,777,214 hosts
  • For Class B, there are 16,384 possible networks and 65,534 hosts
  • For Class C, there are 2,097,152 possible networks and 254 hosts

    What is the standard color sequence of a straight-through cable ?

    You need to connect two computers for file sharing. Is it possible to do this without using a hub or router ?

    Yes, you can connect two computers together using only one cable. A crossover type cable can be use in this scenario. In this setup, the data transmit pin of one cable is connected to the data receive pin of the other cable, and vice versa.

    What is ipconfig ?

    Ipconfig is a utility program that is commonly used to identify the addresses information of a computer on a network. It can show the physical address as well as the IP address.
