a neighborhood, networks also use a two-part address to identify individual hosts on that network. Addressing 0:48-3:12 For example, we may have a computer here on this network that has the number 1 assigned to it.This is the host address, but the network it's connected to also has an address--in this case, 192.168.1. Just as a house in a neighborhood has a house number and street address, a computer on a network has a host address and a network address. If you combine the two together, we can uniquely identify that host on the network in the same way that a house and a street address uniquely identifies a particular house in a neighborhood. Suppose there's a second street in this neighborhood and this street is called Elm Street, and it intersects with Oak Street and it's connected to several other houses. Just as on Oak Street, each of these houses has its own number. You may notice here that this house on Elm Street has exactly the same number as this house over here on Oak Street. Suppose you're a postal worker and you have an envelope that's addressed to house 732.Without a street address, you wouldn't know which of these houses should get that particular envelope. Should it be 732 Oak or 732 Elm? Because these houses each have a two-part address, 732 Elm and 732 Oak, we can identify which house a particular piece of mail goes to. It works in exactly the same way on a computer network. We could have two computers on two different networks that have the same host number assigned to them. We could have a host on this network that's assigned the number 1, and a host on this network that's assigned the number 1 as well. However, we can identify them uniquely from each other by looking at the network address as well. The host on this side has a network address of 192.168.1. The host on this other side has a network address of 10.0.0.By combining the two together, we can uniquely identify the host on these two networks in the same way that we differentiate between two different houses with the same house number that are on different streets. Notice in this diagram that these two networks are actually connected to each other, forming a larger network with all the other computers. This network could be connected to an even larger network. If the only word we had to describe these connections were "network," it would really be difficult to know which network we're talking about. Therefore, we need to introduce some new terminology. Subnet 3:13-3:37 Each of these separate networks represent a subnet. A subnet is a part of the network where all of the computers share the same subnet address, in much the same manner that all of the houses on the same street share the same street address in their addresses. Sometimes you'll hear a subnet address referred to as a network address. They're the same thing. Best practice is to use the term subnet address.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
