Memory Resident (often abbreviated as MemRes) is a term used to describe a program or software that resides in the computer’s RAM memory without needing to be reloaded from a storage device each time you use it. Memory resident programs can increase system performance by reducing the amount of time required to load and execute certain processes.
Memory resident programs are typically designed to run in the background, as they are used to increase system performance and performance monitoring. The most common type of memory resident program is an antivirus program, which automatically checks for the presence of malware on the system when the computer is idle. It can also be used for other security-related tasks, such as detecting and preventing the execution of malicious code.
Memory resident programs are also used for tasks such as application and driver optimization, system configuration and automation, system performance monitoring, and system diagnostics. Such programs are often referred to as “Tasks” in the Windows environment.
The memory resident programs are designed to be invisible to the user when running and tend to take up a small amount of space in the RAM memory. As such, they are ideal for systems with limited RAM resources, as they can help improve the system’s overall performance without taking up too much of the available memory.
Although memory resident programs are beneficial for system performance, they should be used with caution, as there is a small risk that security vulnerabilities exist in the system due to bugs in the memory resident program itself. Additionally, some antivirus programs can flag memory resident programs as potential malicious software, as they can be used to tamper with system configuration and other settings. Therefore, it is best to exercise caution when installing memory resident programs.
