Intel has released processor with a variety of bus / memory widths. The 386SX had a 16-bit data width, the 386DX and 486 had a 32-bit bus width, and the Pentium had a 64-bit data bus.
Different microprocessor can address different amounts of memory. The motherboard design should allow for maximising the physical memory to what the microprocessor can address
32 bit
44 bits
The data width of a CPU is the bit rate. The Intel makes 2 types of Pentium 4's, one with 32 bits and the other with 64 bits.
32 bit is the default.
50 bits.....
The first IBM PC (the IBM 5150) used the Intel 8088 a version of the Intel 8086 with a multiplexed 8 bit databus instead of the full width 16 bit databus, to reduce package size and cost. IBM had also considered using the Motorola 68008 a version of the Motorola 68000 with a multiplexed 8 bit databus instead of the full width 16 bit databus, to reduce package size and cost; but Motorola could not promise delivery until a year later (due to fabrication problems) and Intel had their chip ready on the shelf.
The differences are given below: 80286 1. Low data bus width (16 bit) 2. Returning from protected mode to real mode is hard and complicated. 3. Small RAM/Memory 80386 1. High data bus width (32 bit) 2. Easy for 80386 3. Big RAM / Memory (Real memory = 4GB and virtual memory= 64TB)
The lines must be the same width as the diameter of the goal posts and crossbar. They must not exceed 12 cm.
The 72 tells you the memory's data-path width. In the case of a width of 72, you're looking a ECC memory. If the width where instead x64, then you'd have standard non-ECC DIMMs.
2 lines the same width apart are parallel.
Row width does not adjust. You can adjust column width or row height.
