Detailed explanation-1: -Explanation: The base address that marks the starting address of the segment in physical memory is decided by the operating system and is of 32 bits.
Detailed explanation-2: -It’s each table entry has: Base Address: It contains the starting physical address where the segments reside in memory. Limit: It specifies the length of the segment.
Detailed explanation-3: -In computing, a base address is an address serving as a reference point ("base") for other addresses. Related addresses can be accessed using an addressing scheme. Under the relative addressing scheme, to obtain an absolute address, the relevant base address is taken and an offset (aka displacement) is added to it.
Detailed explanation-4: -The memory address of the first element of an array is called first address, foundation address, or base address.
Detailed explanation-5: -The idea of segmented memory addressing is fairly simple. Addresses are divided into two parts: a segment number and an offset. Offsets (usually 16 bits) are used most of the time, where the additional high-order bits are held in one or more special segment registers and assumed for all operations.
