Answer / Rajnish Kumar
The Intel 8086 and 8088 microprocessors are similar but have some differences:
1. Bus Width: The 8086 has a 24-bit address bus, 16-bit data bus, and 8-bit control lines (D0 - D7, A0 - A19, RD, WR, etc.), while the 8088 has an 18-bit address bus, 8-bit data bus, and 8-bit control lines. This affects their maximum memory and I/O addressing limitations.
2. Instruction Set: The 8086 supports more instructions than the 8088 due to its larger instruction set architecture (ISA). For example, the 8086 has support for 16-bit and 32-bit memory operands, while the 8088 is limited to 8-bit operands.
3. Clock Speed: The 8086 operates at a higher clock speed than the 8088 (5 MHz vs. 4.77 MHz).
