| Mobile computing devices | Portable, light-weight computers comparable to a desktop in capability |
| Tablet PCs | Similar to pad/pencil |
| Tablet Computer | Very similar to a tablet PC except that it runs special software different from a desktop computer |
| Smart phones | behave very similar to tablet computers and often can run the same software. Have cameras, video, mp3 players, and other computer like features. |
| Wearable computer | Designed to be worn In clothing Wristband MP3 players, hands-free cell phones Monitor health problems |
| Server | used to manage or provide services for other computers. |
| File Server | provide storage access to multiple users |
| Web Server | host a website |
| Print Server | host a printer |
| Domain Controller | a special server which runs a network- used in businesses |
| Media Server | a special type of file server most common in a home which hosts files that can be played on multiple displays are devices through the home |
| CPU | Processes data and controls the flow of data between the computer’s other units. |
| ALU | Performs logic and arithmetic operations |
| MPU | have up to 8 “brains”. They can for the first time perform more than one operation at the same time! |
| Fetch | Once the program is loaded, the processor requests the first line of code from cache or RAM. |
| Execute | The Arithmetic/Logic Unit, Floating Point Unit (FPU), or GPU performs the operation. |
| Decode | The control unit interprets the instruction and moves data to the appropriate registers. |
| Cache Memory | is high speed memory. 1 cache is within the CPU itself. |
| L1 | This cache is very high speed and stores instructions executed over and over. |
| L2 | is a slower and larger version of L1 cache |
| L3 | is now included on most current CPUs and further speeds up operation |
| GPU | The Arithmetic/Logic Unit, Floating Point Unit (FPU), or GPU performs the operation. |
| RAM | holds data for all applications that are currently running on your computer, but only while the power is on. |
| DDR | Double Data Rate which means the computer reads data from the RAM at least two times per cycle. |
