Shared memory
* Shared memories enable the computers to communicate various informations.
* is the fastest inter-process communication mechanism
  - used by shared libraries
* is used for buffering
  - chunks of data to be read and written
  - reading and writing data buffers
* is used to allow the two to communicate with each other

### representation | memory:

Virtual memory
* Explain the concept of virtual memory.
* allows programs to use hard disc space to supplement the memory available.
* creature of Windows.
* is even a form of caching
* is the first link in the bridge between disk and processor speeds
  - idea that the application 'sees' a 'block of memory' of a given size
  - usually much larger than physical memory
* makes it possible to use more memory than is physically in the computer.
* mechanism for getting extra memory.
* provides a means to protect the address space in various ways.
* trick used to expand the total amount of memory available.
+ Virtualization: Computing
  * Virtual memory makes it possible to use more memory than is physically in the computer. The computer figures out a way to write contents of certain memory blocks to disk.
  * Virtual memory is the idea that the application 'sees' a 'block of memory' of a given size. The application can use this memory as it sees fit. This block of memory is 'virtual' in the sense that it comes from different parts. Some of it may be in the main memory of the computer, but some may also be on disk. The CPU has a special part, called Arithmetic Logic Unit which does some of the translations between application memory and system resources. Modern operating systems also do a part of this work.

Visual memory
* Visual Memory Helps to develop visual concentration and sequential memory skills.
* helps users remember what they learned.
* involves the right side of the brain and verbal the left side.
* is another part of visual perception
  - required for spelling and for remembering how to form letters
* requires input of information through visuo-perceptual channels.

Mental image
* are primarily symbolic representations.
* can be quite detailed but they tend to be less detailed than actual perception.
* contain the nonverbal aspects of understanding.
* have hierarchies.

Overlap
* is concurrences
  - representations
