<processor> An addressing mode found in many processors' instruction sets where the instruction contains the address of a memory location which contains the address of the operand (the "effective address") or specifies a register which contains the effective address. In the first case (indirection via memory), accessing the operand requires two memory accesses - one to fetch the effective address and another to read or write the actual operand. Register indirect addressing requires only one memory access. An indirect address may be indicated in assembly language by an operand in parentheses, e.g. in Motorola 68000 assembly MOV D0,(A0) writes the contents of register D0 to the location pointed to by the address in register A0. Indirect addressing is often combined with pre- or post- increment or decrement addressing, allowing the address of the operand to be increased or decreased by one (or some specified number) either before or after using it.

indirect address

<networking> Conversion of an Internet address into the corresponding physical address (Ethernet address). This is usually done using Address Resolution Protocol. The resolver is a library routine and a set of processes which converts hostnames into Internet addresses, though this process in not usually referred to as resolution. See DNS. (1996-04-09)

An indirect branch (also known as a computed jump, indirect jump and register-indirect jump) is a type of program control instruction present in some machine language instruction sets. Rather than specifying the address of the next instruction to execute, as in a direct branch, the argument specifies where the address is located.

The indirect pathway, sometimes known as the indirect pathway of movement, is a neuronal circuit through the basal ganglia and several associated nuclei within the central nervous system (CNS) which helps to prevent unwanted muscle contractions from competing with voluntary movements. It operates in conjunction with the direct pathway.

The hardware address of a device connected to a shared network medium. See also Media Access Control.

Free indirect speech is a style of third-person narration which uses some of the characteristics of third-person along with the essence of first-person direct speech; it is also referred to as free indirect discourse, free indirect style, or, in French, discours indirect libre.

1. <networking> e-mail address. 2. <networking> IP address. 3. <networking> MAC address. 4. <storage, programming> An unsigned integer used to select one fundamental element of storage, usually known as a word from a computer's main memory or other storage device. The CPU outputs addresses on its address bus which may be connected to an address decoder, cache controller, {memory management unit}, and other devices. While from a hardware point of view an address is indeed an integer most strongly typed programming languages disallow mixing integers and addresses, and indeed addresses of different data types. This is a fine example for {syntactic salt}: the compiler could work without it but makes writing bad programs more difficult. (1997-07-01)
