a. Operand: In
all computer languages, expressions consist of two types of components: operands
and operators.
Operands are the objects that are manipulated and operators are the symbols
that represent specific actions. For example, in the expression 5 + x,
x and 5 are operands and + is an operator. All expressions have at
least one operand.

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: Opcode is an short for
Operation Code, which is the part of an instruction in machine language to
specify the operation to be performed. A complete machine language instruction
consists of an opcode and zero or more operands with which the specified
operation is performed. Examples are “add memory location A to memory location
B,” or “store the number five in memory location C.” “Add” and “Store” are the
opcodes in these examples.

Address Locator: Address locator also referred to as geo-locator or
internet protocol (IP) address is a computer algorithm that is used to specify
the location of a given computer.
