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: Registers are special, high-speed storage area within the CPU. All data must be represented in a register before it can be
processed. For example, if two numbers are to be multiplied, both numbers must
be in registers, and the result is also placed in a register. The number of
registers that a CPU has and the size of each (number of bits) help determine the power and speed of a CPU. For
example a 32-bit CPU is one in which each register is 32 bits wide.

c.
Mnemonic Code: A word or
string which is intended to be easier to remember than the thing it stands for
such as that used in assembly language which employs mnemonics as a memory aid.
For instance, ADD to represent addition, CLR for clear, or SQR for square root.

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.
