Expanded memory

Expanded memory is a type of random-access memory (RAM) that is designed to provide extra memory for computers. It is typically used in conjunction with a memory management unit (MMU) to increase the amount of memory that can be accessed by the system.

Expanded memory is typically used to store data that is not frequently accessed, such as video data or images. It can also be used to store data that is too large to fit into the main memory of the computer. When expanded memory is used, the computer can still access the data in the main memory, but it will take longer to retrieve the data from the expanded memory.

Expanded memory is not as fast as the main memory, but it is much faster than the hard disk drive or other storage devices. What is PC extended memory? PC extended memory is a type of computer memory that is available on some models of IBM PC compatible computers. It is an extension of the original IBM PC memory management system and allows for up to 4 GB of RAM to be addressable by the computer.

What is extended memory in BIOS? Extended memory is a type of random access memory (RAM) that is used in computers. It is an expansion of the conventional RAM and is used to store data that is not frequently accessed by the CPU. Extended memory is typically used for applications that require large amounts of data to be stored, such as video editing or 3D rendering.

What is vertical memory expansion?

Vertical memory expansion is a process by which the capacity of a computer's memory is increased by adding additional modules to the existing memory configuration. This can be done by adding more memory modules to the existing configuration, or by replacing the existing modules with larger capacity modules. The process of vertical memory expansion is often used to increase the amount of memory in a computer system when the existing memory configuration is no longer sufficient to meet the needs of the user.

How do you use expanded memory?

If your computer is running MS-DOS 6.0 or higher, you can use Expanded Memory Specification (EMS) memory to run memory-intensive programs. EMS is a type of Random Access Memory (RAM) that is designed to work with special EMS software drivers.

To use EMS memory, you must have an EMS memory board installed in your computer. The EMS memory board contains special chips that control the EMS memory.

Once the EMS memory board is installed, you must configure your computer to use EMS memory. To do this, you must edit your CONFIG.SYS file and add the EMM386.EXE line. For example:

DEVICE=C:DOSEMM386.EXE

Once you have configured your computer to use EMS memory, you can install EMS-compatible software. This type of software is designed to work with the EMS memory board.

To use EMS memory, you must first load the EMS driver. To do this, type EMM386 at the MS-DOS prompt.

Once the EMS driver is loaded, you can use the EMM386.EXE command to allocate EMS memory. For example, to allocate 64K of EMS memory, you would type the following at the MS-DOS prompt:

EMM386.EXE 64000

You can also use the EMM386.EXE command to deallocate EMS memory. To do this, type

Is Extended Memory RAM?

Extended memory is RAM that is used to extend the available address space on a computer. It is typically used in conjunction with extended memory addressing (EMA) to allow for more than 4 GB of addressable memory.

Extended memory is RAM, but it is a specific type of RAM that is used to extend the available address space on a computer. It is not the same as the RAM that is used for general purpose computing.
