Week 12 - Muddy

There was a lot of information in this week it was a little diffecult to keep up with it all. over all learning about everything was pretty interesting however. Learning about all the types of networks we have PAN which is personal area, LAN local area network, MAN metropolitan area, and WAN wide area network which is the internet. also learning about all the addresses that keep you connected to the internet like how your TCPIP address consists of 32 bits. there was a lot of information about the LAN and WAN area networks. How with LAN there is multiple ways to get LAN such as ethernet LAN twisted pair of copper wire but you can fall into problems with this because it needs to be installed the right way or it may not work also it is not to good if you decide to extend your internet access width because it is only for a certian length. Fiber opics is another form where there is no electromagnetic interferance such as a lightning storm.

Also it was interesting learning about NIC which is a network interface card this connects nodes to networks it can be integrated on your computer or even on a USB port and every NIC is unique. The NIC knows who you are but not where you are kind of like a social security number. The hub is where all computers are hooked up to one network and everything that is sent out is sent out to every computer this can have security issues that is why a lot of people will pick switch instead where you can pick who you want to send information to.
