WebIt is a collection of wires that carries electrical signals (Logic ‘0’ or ‘1’) in and out of CPU. As per the information carried by these set of wires (or Bus), the Bus architecture is divided into: Address-bus that carries physical address of memory or I/O storage locations), Data-bus that carries data to be read or written into the memory or I/O location.

WebPC's CPU (called an 8088) only contain 16 bits. A 16-bit address can only uniquely identify 64 Kilobytes (as opposed to the full 1 Megabyte that requires 20 bits for addressing). With a 16-bit address, we can only access a range of 64K bytes within the full 1M bytes of the computer's memory. However, WebAs previously noted, on Intel 8088 hardware, "real" memory addresses are 20-bits, a combination of a 16-bit segment and a 16-bit offset address. For code, the 20-bit address is derived from a combination of the CS (Code Segment) and IP (Instruction Pointer) registers. galltec edj2/2
