​KembaraXtra-Computer Terms – base address:


A base address is a reference location in memory used as the starting point for calculating the exact position of data within a memory segment. It forms the constant portion of a two-part memory addressing system. The base address itself does not identify the exact byte of data but instead establishes the beginning of a memory region. To locate the precise memory location, an offset value is added to the base address, producing the absolute address where the data is stored.


This method of addressing is commonly used in computer architectures that organize memory into segments. For example, in certain personal computers, memory locations are identified relative to the start of a segment. The concept is similar to street addressing: the base address corresponds to the beginning of a block, while the offset represents the specific number within that block. By combining the base address with the offset value, the system determines the exact memory location needed to store or retrieve data.
