a. Operand: In
computer programming, an operand
is a term used to describe any object that is capable of being manipulated. For
example, in “1 + 2” the “1” and “2” are the operands and the plus symbol is the
operator.

b. Registers: A register is a very small amount of very fast memory that is built into the CPU (central processing unit) of a
computer in order to speed up its operations by providing quick access to
commonly used values.

c. Mnemonic Code: A computer programming term in computer programming language that uses some people-friendly commands in
order to be readily memorised by human programmers. Example of mnemonic codes
includes, LDA {value} which means Lead the Accumulator with a given value.
Another example is STO E,A which means store the content of register E in
register A.

d.
Opcode: The part or parts of a machine language instruction which determines what kind of action the computer should take, e.g. add, jump, load, store. In any particular instruction
set certain fixed
bit positions
within the instruction word contain the op code, others give parameters
such as the addresses or registers involved.

Address Locator: The address locator is the main tool for geocoding.
It is a dataset that contains information including address attributes,
indexes, and queries for geocoding.
