Each time you turn on your computer, Windows keeps track of the way your computer starts and which programs you commonly open. Windows saves this information as a number of small files in the prefetch folder. The next time you turn on your computer, Windows refers to these files to help speed the start process. The prefetch folder is a subfolder of the Windows system folder. The prefetch folder is self-maintaining, and there's no need to delete it or empty its contents. If you empty the folder, Windows and your programs will take longer to open the next time you turn on your computer.

What does prefetch 2n mean in regards to a ddr memory module?
DDR1 has a prefetch of 2n, which means it can store 2 bits of data in each prefetch buffer.
Prefetch data in Windows XP is parsed into what folder?
Try c:\windows\prefetch
Super fetch has stopped working windows?
To correct the problem you need to delete everything in the prefetch folder.Perform Start - Run - Prefetch (type in prefetch) - Press Now delete everything in the Prefetch folder.Close out and reboot and you should be good to go.

What does a DDR memory module with a prefetch of 4n mean?
It can store 4 bits of data in each prefetch buffer. It also means that it is a ddr2 memory module
What is the use of insertion queue in 8086?
Maybe you mean the prefetch queue?
What does the word prefetch mean?
The "Prefetcher" is a component of Microsoft Windows, that helps speed up the Windows boot process and helps to speed up start up programs. One should never clean out the "Prefetch" folder, as this could cause severe problems.
Explain the following description of a memory module DDR3 PC10600 1333MHZ?
DDR3 memory uses less power. This reduction comes from the difference in supply voltages. The 1.5 V supply voltage works well with the 90-nanometer fabrication technology used in the original DDR3 chips. Some manufacturers further propose using dual-gate transistors to reduce leakage of current. and the benefit is its prefetch buffer, which is 8-burst-deep. In contrast, the prefetch buffer of DDR2 is 4-burst-deep, and the prefetch buffer of DDR is 2-burst-deep. An advantage is an enabling technology in DDR3's transfer speed.
What is computer daily maintenance?
These steps will help keep your PC running well and efficiently...Empty Recycle Bin Uninstall unused programsEmpty prefetch cache Disk Cleanup
What is the Windows XP Prefetch Folder used for?
this folder is used to store your used history, that folder should be cleaned regularly, otherwise it may make your pc little bit slow....
How do you switch from real mode to protected mode in 80386?
To switch from real mode to protected mode in the 80386, set the PE bit in the MSW in CR0, and then immediately execute a JMP to flush the prefetch queue.
What processor begins fetching a second instruction before it completes the machine cycle for the first instruction?
almost all modern computers do this (the exceptions are typically simple microcontrollers ). various methods can be used:prefetchpipeliningcachesetc.The first computer to do this was the IBM 7030 Stretch transistorized supercomputer introduced in 1961 (it had no integrated circuits at all in it). It used a combination of prefetch, pipelining, and caches to do this. One computer that I used that implemented prefetch (without pipelining, caches, or other mechanisms) to an extreme was the Delco Magic V implementation of the MIL-STD-1750A architecture. It had a prefetch unit with a FIFO buffer that could store roughly 20 instructions before they were needed by the address evaluation and operand read unit which had another FIFO buffer which could store roughly 20 instructions their operands and the address to store the results to before they were needed by the execution unitwhich had yet another FIFO buffer which could store roughly 20 results and the address to store those results tobefore they were needed by the memory storage unit. In all roughly 60 instructions could be held waiting to be processed between prefetch and storage of results to memory. Multiple levels of scoreboard synchronization logic were used to prevent the prefetch unit and address evaluation and operand read unit from accessing memory or registers pending modification by the memory storage unit or execution unit.
