LPX (short for Low Profile eXtension), originally developed by Western Digital, was a loosely defined motherboard format (form factor) widely used from 1987 to the late 1990s. [ 1 ] [ 2 ]
DECpc was a wide-ranging family of desktop computers, laptops, servers, and workstations sold by Digital Equipment Corporation.The vast majority in the family are based on x86 processors, although the APX 150 uses DEC's own Alpha processor.
Software can "partition" a portion of a computer's RAM, allowing it to act as a much faster hard drive that is called a RAM disk. A RAM disk loses the stored data when the computer is shut down, unless memory is arranged to have a standby battery source, or changes to the RAM disk are written out to a nonvolatile disk.
A RAM drive has much faster read and write access than a hard drive with rotating platters, and is volatile, being destroyed with its contents when a computer is shut down or crashes [1] —volatility is an advantage if security requires sensitive data to not be stored permanently, and to prevent accumulation of obsolete temporary data, but ...
SoftRAM was designed for use with Windows 3.1.It was launched in March 1995 and sold more than 100,000 copies. [2]Most out-of-memory errors in Windows 3.x were caused by the first megabyte of memory in a computer, the conventional memory, becoming full.
The maximum random access memory (RAM) installed in any computer system is limited by hardware, software and economic factors. The hardware may have a limited number of address bus bits, limited by the processor package or design of the system. Some of the address space may be shared between RAM, peripherals, and read-only memory.
Laptop or notebook, a form of portable computer with a clamshell design. Subnotebook, ultra-mobile PC, netbook, and tablet computer, various form factors for devices that are smaller and often cheaper than a typical notebook. Mobile phone, including a wide range of sizes and layouts.
Extended memory is located above 1 MB, includes the high memory area, and ends at 16 MB on the Intel 286 and at 4 GB on the Intel 386DX and later.. In DOS memory management, extended memory refers to memory above the first megabyte (2 20 bytes) of address space in an IBM PC or compatible with an 80286 or later processor.
