Catching Up

I was either out sick or unable to come in to the office for the majority of last week. So here's a catch-up of what I've been up to:

I've learned about IP, or Internet Protocol, and IP Addresses. I've learned how to assign a Static IP to a computer or network of computers. 192.168.X.X is the IP address used for most networks. I've also learned about masking, and how a subnet mask protects each computer from interfering the IP of other computers under the same network. The network mask for the 192.168.X.X example is 255.255.255.0.  I then learned about DHCP, Dynamic Host Configuration Protocol. It reduces or even eliminates the need to manually set up a Static IP. It has a range of IP addresses reserved for the network and when devices request to connect to the network it assigns them an IP address for a certain amount of time, a "lease". when the lease is up, you'll have to renew it in order to maintain connection to the network.

I've also studied USB, Universal Serial Bus, and the differences between the original USB 1.1, USB 2.0, and USB 3.0. While the biggest difference is transfer speed, there are several functional additions made to USB 2.0 worth noting, specifically the ability to associate multiple interfaces with the same device function, meaning you can unplug a device and plug it into a different slot and it will still recognize the device's programming.
