Basadress

Basadress is a nonstandard term that appears in some texts as a variant spelling of base address. In computer science, the base address refers to the starting memory location of a block of data or a program segment, from which other addresses are calculated by adding offsets.

In practice, base addresses are used during program loading and relocation. A loader maps a program’s code and data into a process’s address space and assigns a base address to the executable sections. When a program accesses a memory location using a relative or offset-based reference, the system computes the actual address as base address plus the offset. This mechanism supports position independence, dynamic relocation, and the separation of a program’s logical layout from its physical placement in memory.

Base addresses are also relevant in architectures that employ segmentation or memory protection. In such systems, a base register or a relocation table may store or reference the base address for a given segment, enabling controlled access and address translation. Relative addressing, pointers, and access to memory-mapped I/O often rely on base addresses to calculate concrete addresses at runtime.

Note on terminology: basadress is not widely recognized as a standard term. In most technical writing the standard phrase is base address or starting address. If basadress is encountered, it should be interpreted in its specific context, and readers are advised to verify whether it denotes the conventional base address or a context-specific concept.
