TCPIP protocol sweet remembers an entire suite and of course guess so I do my due diligence TCP is OSI layer 4 so this is called the transport layer a transmission control protocol transport layer all mixed assets so let's talk about 400-101 the components a bitTCPIP I network a us so you understand you know what you're looking at when you when you're when you're looking at TCPIP to bug bites the first thing is what is called the Padres so the IP address is something that you’ll see you'll see it like 10 doubt 1.2 handout 1 but sec that is an IP address I addresses our addresses that are used to signify every computer or device on the network every computer or device on a TCP IP Persian for network needs an IP address that one that 1001192 168 ad a 1.1 acceptor a 2007 the 65 about 40 4.1 these are all IP addresses so every device on the network needs up what's called and IP address so then actually have the IP address you have something called the subnet mask now in the next section we're going to talk more a lot more about the subnet mask so we’re just going to going to just Kong glaze over right here this subnet mask is basically a way to segment a network a logically are so that that different computers in different devices cannot necessarily talk to other computers 400-101 and devices on the same physical network so basically if you have a large network let's say you have a um I don't 200 computers on a network you don't necessarily want all those computers to be able to talk to each other even though they're physically connected to the same network you can prevent them from talking teach other by putting in this thing called a subnet mask in the subnet mask again I guess they were at talk about it and and an exceptional about now the next thing after do. the subnet masks something called the default gateway the default gateway he's you were out her for thissubnetwork that you are on so basically what the default gateway allows is your.
