I have created an easy to read Subnet Mask Network Reference Chart to memorize. This chart will help you calculate subnet mask networks and hosts easier in your head. Example: You can calculate every time you want to Create a new network, or you can refer to this chart to get the same results. This can be a big help when taking the Network+ Test, so memorize this chart and when you take the test, just write it out on paper for reference.

The OSI (Open System Interconnection) Model is a Network Reference Model developed by the International Organization of Standardization to define the basic Standards for All network communication. I have read about it, seen it in action and have taken some time to understand its function because it is imperative to know and understand in the Networking Field. I have gathered some information from different sources and have come up with a simple image of the OSI Network Model for quick reference for anyone to use.

Here I have Power Defragmenter and PageFile Defragmenter. Enjoy.
