The RAM limit in the Macintosh design was 4 MB of RAM and 4 MB of ROM with the remaining 8 MB addresses split between the SCC, IWM and VIA chips, because of the structure of the memory map. [9] [10] This was fixed by changing the memory map with the Macintosh II, allowing up to 8 MB of RAM, by shrinking ROM and I/O addresses to 1 MB each and ...
Disk Cleanup (cleanmgr.exe) is a computer maintenance utility included in Microsoft Windows designed to free up disk space. It was introduced in Windows 98 and has been a part of Microsoft Windows ever since.

Second, the maximum throughput of a RAM drive is limited by the speed of the RAM, the data bus, and the CPU of the computer. Other forms of storage media are further limited by the speed of the storage bus, such as IDE (PATA), SATA, USB or FireWire. Compounding this limitation is the speed of the actual mechanics of the drive motors, heads, or ...
It is required, however, for the boot partition (i.e., the drive containing the Windows directory) to have a page file on it if the system is configured to write either kernel or full memory dumps after a Blue Screen of Death. Windows uses the paging file as temporary storage for the memory dump.
Off-line storage is computer data storage on a medium or a device that is not under the control of a processing unit. [9] The medium is recorded, usually in a secondary or tertiary storage device, and then physically removed or disconnected. It must be inserted or connected by a human operator before a computer can access it again.
