To obtain an offset address, you typically start with the base address of a memory segment and add the desired offset value to it. In programming, this can be done using pointer arithmetic. For example, in C or C++, if you have a pointer pointing to a base address, you can obtain the offset address by adding an integer value to that pointer. The resulting address points to a specific location within the memory segment relative to the base address.

What is use of offset address in 8086 mp?
Offset address is also known as displacement.By adding this offset value to a base address,address of a specific locaction in memory can be accessed
What is offset address?
An offset address is a relative address rather than an absolute address. You use offsets to refer to memory relative to an absolute address. For instance, array indices are implemented using offsets from the start address of the array, such that element 0 is at offset 0 and element 5 is at offset 5.
What is the offset for a Class C IP address?
The offset for a Class C IP address is 24 bits.
What is base address and offset address?
In software Engineering KPA denotes.
In the Base plus Offset addressing Offset address is also known as?
Base plus displacement.
Can physical address and virtual address be same?
your question is wrong. it should be "can physical address and logical address be same" answer is no because logical address is the combination of page number and offset whereas physical address is the combination of physical page[frame] and offset
What is the physical address 8086 assembly instruction?
In 8086 assembly language, a physical address is the actual memory address used by the CPU to access data. It is calculated by combining a segment address with an offset address. The segment address is typically stored in one of the segment registers (CS, DS, SS, or ES), and the offset is specified in the instruction. The formula for calculating the physical address is: Physical Address = (Segment Address × 16) + Offset.
How would you obtain a far address from segment and offset address of a memory location?
Pointers to far objects are stored using four bytes (32 bits). The bytes are stored little endian or low to high order. The first word contains the 14-bit memory offset (bits 14 and 15 are always 0). The second word contains the page number (or segment number for function pointers). The memory address is calculated as follows: Variable Address = (Page * 0x4000L) + OffsetFunction Address = (Segment * 0x10000L) + Offset
How do you calculate instruction address and data address give example?
To calculate an instruction address and a data address, you typically use the base address and an offset. For example, if the base address of a program is 0x1000 and the instruction is located at an offset of 0x0040, the instruction address would be calculated as 0x1000 + 0x0040 = 0x1040. Similarly, if a data item is stored at an offset of 0x0020 from the same base address, the data address would be 0x1000 + 0x0020 = 0x1020.
What is offset in 8086 mp?
displacement from base address
What is the offset in a hexadecimal code?
The offset is usually the difference between the address of a module and the specific location being referenced.
How can one calculate the physical address from a given logical address?
To calculate the physical address from a logical address, you can use the base address and offset. Add the base address to the offset to get the physical address. This process is commonly used in computer systems to translate logical addresses to physical addresses for memory access.
