1. The JUMP GROUP Unconditional Jump (JMP).
a. Short Jump (relative jump).
They can be moved along with their related software, to
any location in the current code segment without a change.
JMP SHORT NEXT
JMP NEXT NEXT: 8-bit displacement
b. Near Jump.
it is similar to the short jump, except that the distance is
farther.
JMP START START: 16-bit displacement

2. c. Far Jump.
obtains a new segment and offset address to
accomplish the jump.(80286-P4).
JMP FAR PTR START
d. Jump with Register Operands.
JMP AX
e. Indirect Jump using an Index.
JMP TABLE[SI]

3. 2. Conditional Jump.
JA NEXT jump if above
JB NEXT jump if below
JS NRXT jump if sign(-ve)
LOOP.
It is combination of a decrement CX and the JNZ.
