Detailed explanation-1: -In the 8086, the internal data bus comprises 16 separate lines, with each line carrying one 1 or one 0. The word size and the number of lines for the internal data bus are equal. The 8086, for example, has a 16-bit word size, and 16 lines carry 16 bits on the internal data bus.
Detailed explanation-2: -This means in total, for 256 bits of memory, we only need 35 wires-1 data wire, 1 write enable wire, 1 read enable wire, and 16 rows and columns for the selection. That’s significant wire savings! But we need a way to uniquely specify each intersection.
Detailed explanation-3: -The size of the address bus determines how much memory the CPU can address directly. For example, a 20-bit address bus can access up to one megabyte (1MB); 24 bits reaches 16MB, and 32 bits can handle four gigabytes (GB).
Detailed explanation-4: -AMD used HyperTransport to replace the front-side bus in their Opteron, Athlon 64, Athlon II, Sempron 64, Turion 64, Phenom, Phenom II and FX families of microprocessors.
