DESCRIPTION
I really am just uploading this, as I need access to a book. On this site if I upload something I can download for free. There really is no need to download this file... It really contains no information. At this point I am just typing to fill the word quota. I shall throw in some symbols and other neat characters to try and trick this website. *& is &* since 2.0 downloaded this on Jiklosm site ∆∆ TY˙ƒ® is cool.

How to use Activity Monitor
Activity Monitor shows the processes that are running on your Mac, so you can see how they affect your Mac's activity and performance.
This article describes some of the commonly used Activity Monitor features. For more information, open Activity Monitor and choose Help>Activity Monitor. You can also see a short description of many items in the Activity Monitor window by hovering the mouse pointer over the item.
OverviewThe processes shown in Activity Monitor can be user apps, system apps used by OS X, or invisible background processes. Use the five category tabs at the top of the Activity Monitor window to see how processes are affecting your Mac in each category.
CPU
Memory
Energy
Disk
Network
Add or remove columns in each of these panes by choosing View > Columns from the menu bar. The View menu also allows you to choose which processes are shown in each pane:
CPUThe CPU pane shows how processes are affecting CPU (processor) activity:
More information is available at the bottom of the CPU pane:
You can also see CPU usage in a separate window or in the Dock:
MemoryThe Memory pane shows information about how memory is being used:
More information is available at the bottom of the Memory pane:
For more information about OS X memory management, refer to theApple Developer website.
EnergyThe Energy pane shows overall energy use and the energy used by each app:
More information is available at the bottom of the Energy pane:
As energy use increases, the length of time that a Mac can operate on battery power decreases. If the battery life of your portable Mac is shorter than usual, you can use the Avg Energy Impact column to find apps that have been using the most energy recently. You can quit those apps if you don't need them, or contact the developer of the app if you notice that the app's energy use remains high even when the app doesn't appear to be doing anything.
DiskThe Disk pane shows shows the amount of data that each process has read from your disk and written to your disk. It alsoshows "reads in" and "writes out" (IO), which is the number of times that your Mac accesses the disk to read and write data.
The information at the bottom of the Disk pane shows total disk activity across all processes.The graph moves from right to left and updates at the intervals set in View > Update Frequency. The graph also includes a pop-up menu to switch between showing IO or data as a unit of measurement.The color blue shows either the number of reads per second or the amount of data read per second. The color red shows either the number of writes out per second or the amount of data written per second.
To show a graph of disk activity in your Dock, choose View > Dock Icon > Show Disk Activity.
NetworkThe Network pane shows how much data your Mac is sending or receiving over your network. You can use this information to identify which processes are sending or receiving the most data.
The information at the bottom of the Network pane shows total network activity across all apps. The graph moves from right to left and updates at the intervals set in View > Update Frequency. The graph also includes a pop-up menu to switch between showing packets or data as a unit of measurement. The color blue shows either the number of packets received per second or the amount of data received per second. The color red shows either the number of packets sent per second or the amount of data sent per second.
To show a graph of network usage in your Dock, choose View > Dock Icon > Show Network Usage.
