What is Shadow RAM?
Shadow Random Access Memory (RAM) is a type of memory stored in Ram Stick, which has a duplicate version of the basic input operating system (BIOS) of the computer. In addition to ensuring that the BIOS is never erased, Shadow RAM has an accelerated speed of access, so the computer can start faster. Some computers use BIOS for reasons other than introduction, and this RAM usually helps with it. Many computers with Shadow RAM, especially those that do not need it, allow the user to enable or deactivate RAM at the command. There are few problems associated with using this RAM, but if the computer does not need it, then it will mean that the computer is slightly less memory.
When the computer introduces, it only goes to read (ROM) to access BIOS information. The problem is that ROM is slow, because it is a larger memory storage, so booting from ROM can take a long time. With Shadow RAM, BIOS information is copied from RAM. RAM is about twice as faster than Roma, sothat it will shorten the shoe time in half. If the user sometimes accidentally deletes the BIOS, this RAM will also have information necessary to start the computer.
Most computers only need BIOS to introduce, but others also use it for normal functions. These systems are mostly obsolete or are a certain interface of the command line. The shadow of the RAM holds the BIOS version and the speed of access is higher, so it usually accelerates processes that require the BIOS.
Some systems depend on Shadow RAM and the user cannot change how the computer uses this RAM, but other computers use it as a comfort instead of a necessity. The latter systems usually allow users to disable and enable RAM at any time. Usually it is best to keep it if users do intensive work.
While there are many advantages that have a shadow ram, they also thy some advantages to have it. The part of the RAM is used to hold informationAci on the BIOS, so this sector will be unavailable during processing. If someone uses intense programs that need to work the whole RAM properly, it can hold the computer back. In addition to this scenario, with Shadow RAM turns on, there is no problem, and most users should not notice reduced RAM availability.
