Network - Base Address

In memory allocation, a base address defines the starting or reference location for a block of contiguous memory. The memory may be general-purpose, or it may serve as cache or port memory. Here are some examples of different types of base addresses: n A base I/O (input/output) address is the starting location for the memory area allocated for an I/O port. The processor uses this address to find the correct port when the processor needs to communicate with a device. n A base memory address is the starting location for a block of memory, such as a buffer area. n A base video address is the starting location for video memory.
