These type of instructions control machine functions such as Halt, Interrupt, or do nothing. This type of instructions alters the different type of operations executed in the processor. It is used when no operation is performed. No flags are affected during the execution of NOP.
Q. What is the purpose of HLT instruction?
After a system reset or the acknowledgement of an interrupt, the interrupt enable flipflop is reset, thus disabling the interrupts. This instruction is necessary to reenable the interrupts (except TRAP).

Q. Which class does HLT instruction belong to?
The HLT instruction is a privileged instruction. When the processor is running in protected or virtual-8086 mode, the privilege level of a program or procedure must be 0 to execute the HLT instruction.
Q. What is the best interfacing?
On velour, knit, satin, and terrycloth use sew-in interfacing. Medium weight fusible or sew-in interfacing is a good choice for heavy weight fabrics like heavier gabardine, corduroy, tweed, and canvas if you want a soft effect. For a crisp effect, chose medium or heavy canvas interfacing.
Q. What does interfacing look like?
It is sewn or fused to the wrong side of the fabric to give structure and shape. Common places it is used include collars and cuffs, underneath buttoned areas, in waistbands and in many home decor projects. Interfacing is predominantly white but can also be black or grey. It is very rarely colored.
Q. What is the difference between stabilizer and interfacing?
Interfacing and stabilizers are typically used between two layers of fabric in apparel and accessories. Stabilizers provide structure for projects like tote bags and crafts, whereas interfacing is generally used to provide more body in apparel projects like shirt collars and facings.
Q. What is the purpose of facing?
Facing is mostly used to finish the edges in necklines, armholes, hems and openings. They are also used widely in all other sewing like quilts and home decor items like curtain hems. Shaped facings are cut to match the outside shape of the piece to provide a neat finish, and are often cut from the same pattern pieces.
Q. What can I use if I don’t have interfacing?
Muslin and cotton are the best substitutes for interfacing due to the ease they give for interfacing. They can be best used when pre-washed to avoid shrinkage, then a 3. 5 stitch length or wider baste stitch to substitute fabric for interfacing on the primary fabric.
Q. Where is interfacing used?
Interfacings can be used to: stiffen or add body to fabric, such as the interfacing used in shirt collars. strengthen a certain area of the fabric, for instance where buttonholes will be sewn. keep fabrics from stretching out of shape, particularly knit fabrics.
