Safe WebMemory Resident is a term used in computer science and refers to a segment of computer memory that stays permanently loaded and operational. This type of memory is loaded into the Random Access Memory (RAM) when the computer is first powered on, and remains in memory until the system is powered down or rebooted.
Memory resident software, also called terminate and stay resident (TSR) software, is a type of memory resident program that can run in the background while the system is actively running other programs. These programs are typically small in size, so they are designed to occupy only a small portion of RAM while the user performs other tasks. This type of program usually performs some type of initialization upon being loaded into memory and can remain active and ready for use even when not running in the foreground. Examples of memory resident software include system utilities such as virus scanners, disk defragmenters, and task schedulers.
Memory resident processes, also known as drivers, are a type of software that interact directly with the computer’s hardware or an external device and allow the operating system to communicate with it. These processes remain active and running in RAM until explicitly stopped or until the computer is powered down. Examples of memory resident drivers include system device drivers, such as the graphics card driver and motherboard device driver.
Memory resident code is code that remains loaded in RAM until it is explicitly unloaded or the system is powered down. This type of code is used for interrupts, signal handlers, and any other code that requires constant or near-constant access in order to perform its task. It is also used when the code must execute as fast as possible, since accessing RAM is much faster than accessing hard disk drives.
Overall, memory resident allows programs to stay active and ready to use even when not being explicitly used. This has great potential to improve system performance, but can also lead to resource issues if not properly managed.
