What is MUTEX ? What isthe difference between a ‘thread’ and a ‘process’? What is INODE? Explain the working of Virtual Memory. How does Windows NT supports Multitasking? Explain the Unix Ke el. What ...
Describe segmentation & pipelining in 8086. What is the difference between 8085 and 8086 and 80286? What is the Maximum clock frequency in 8086? 5 Mhz is the Maximum clock frequency in 8086. What are ...
CMP sets arithmetic flags as if subtracting its second operand from its first without storing the result. JE tests equality through the zero flag. JL interprets the comparison as signed, using the sig...
Registers hold values used directly by instructions. In x86-64, RAX names a 64-bit general-purpose register, EAX its low 32 bits, AX its low 16 bits, and AL its low 8 bits. These names refer to overla...
For a multi-byte integer stored in memory, little-endian order places the least significant byte at the lowest address. A 32-bit value 0x12345678 therefore appears as bytes 78 56 34 12 in increasing a...
MOV with a memory source reads stored data, while LEA computes an effective address expression without reading memory at that address. LEA is often used for pointer calculation or limited arithmetic i...
A calling convention defines how arguments and return values are passed, which registers the callee must preserve, and how stack-related obligations are handled. Code that violates it can corrupt the ...
ADD updates arithmetic flags. For signed 32-bit addition, JO branches when the overflow flag is set, meaning the mathematical result is outside the representable signed 32-bit range. Carry indicates a...
