Base plus displacement.
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
displacement from base address
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.
When stored in contiguous blocks, data usually has a base address. Accessing any data from the block requires an offset to the base address which is achieved through an index. The adding of an offset to the base address is called indexed addressing.
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.
The Physical address can be calculated asPhysical address = Base address + Offset.So take Base,Offsets,Lengths in to different arrays and check whether offset is less than length , if it is then the physical address would be base+ Offset , if not then that is a segment error.
Refers to a value added to a base address to produce a second address. For example, if B represents address 100, then the expression,B+5would signify the address 105. The 5 in the expression is the offset.Specifying addresses using an offset is called relative addressing because the resulting address is relative to some other point. Another word for offset is displacement.Ajesh John
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.
The offset for a Class C IP address is 24 bits.
You cannot. The conversion goes this way: segment+offset -> [segment-table] -> linear_address -> [page-table] -> physical_address PS: In most cases there is only one (4GB long) segment (or one code-segment and one data-segment), so offset is quite the same as linear address
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
