a. Operand: Basically,
a computer instruction describes an operation (add, subtract, and so forth) and
the operand or operands on which the operation is to be performed. An operand is the part of a computer instruction that specifies data
that is to be operating on or manipulated and, by extension, the data itself.

b. Registers: Registers are normally measured by the number of bits they can hold,
for example, an “8-bit register” or a “32-bit register”. A processor register is a small amount
of storage available as part of a digital processor, such as a central
processing unit (CPU).

c. Mnemonic Code: Mnemonic codes are easy to
remember short alphanumeric strings that aid the memory of a programmer,
examples on mnemonic codes are MOV for MOVE, CLR for Clear Screen, etc. that
are understood by the computer and command it to perform various operations.

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.
