TCP/IP and Subnet Masking

In this assignment, we were to view the TCP/IP and Subnet Masking tutorial. It focused on the components and concepts in a Transmission Control Program/Internet Program (TCP/IP) Network and how it works. Below are the assignment questions that we had to answer.

Eli the Computer Guy's TCP/IP and Subnet Masking

  1. What is TCP/IP version 6?

    TCP/IP version 6 is the newest version of TCP/IP. It was created to eventually replace IPv4.


  2. What version of TCP/IP will we focus on?

    We will focus on IPv4 because that is still the most used protocol.


  3. What does it mean when we say that TCP/Ip is actually a protocol suite?

    We say that TCP/IP is a protocol suite because it is made up of both TCP and IP protocols.


  4. What is a routable protocol?

    A routable protocol is a protocol that contains the network and device address and allows packets to be forwarded from one network to another.


  5. In TCP/IP what is windowing?

    Windowing is used by TCP as a method of controlling the flow of packets between two computers or network hosts.


  6. How many bits does an IPv4 address have?

    An IP v4 address has 32-bits.


  7. In TCP/IP, what is the default gateway?

    The router for the subnetwork that you are on. It allows you to connect to computers outside of your subnet.


  8. What does a Domain Name Service do?

    Domain Name Service maps domain names to IP addresses. It allows us to use names instead of IP addresses to connect to a site or device.


  9. What is Network Address Translation (NAT)?

    Network Address Translation assigns a public address to a computer within a private network and limits the number of public IP addresses that are used by a particular entity.


  10. In a TCP/Ip address, what is an octet?

    An octet is made up of 8 bits.


  11. What is the purpose of a subnet mask?

    The purpose of a subnet mask is to identify which part of an IP address is part of the network identifier and which part is the device identifier.


  12. What would the subnet mask be if you wanted to use 8 bits for the network address and 8 bits for subnets?

    255.255.0.0


  13. When was the last time that class full addressing was commonly used?

    The last time that class full addressing was commonly used was in 1993.


  14. What replaced class full addressing?

    Classless inter-domain routing (CIDR) replaced full addressing.
