A) Aluminium B) Copper
C) Phosphor Bronze D) Carbon
 
Answer & Explanation Answer: C) Phosphor Bronze

Explanation:

A Slip ring is a ring in a dynamo or electric motor which is attached to and rotates with the shaft, passing an electric current to a circuit via a fixed brush pressing against it.

 

Slip rings are usually made of Phosphor Bronze.

 

Slip ring motors usually have a 'phase-wound' rotor. This type of rotor has a 3-phase, double-layer, distributed winding consisting of coils used in alternators. The rotor core is made up of steel laminations which have slots to accommodate formed 3-single phase windings.

Q:

What is fragmentation? Different types of fragmentation?

Answer

Fragmentation occurs in a dynamic memory allocation system when many of the free blocks are too small to satisfy any request. 


External Fragmentation: External Fragmentation happens when a dynamic memory allocation algorithm allocates some memory and a small piece is left over that cannot be effectively used. If too much external fragmentation occurs, the amount of usable memory is drastically reduced. Total memory space exists to satisfy a request, but it is not contiguous. 


Internal Fragmentation: Internal fragmentation is the space wasted inside of allocated memory blocks because of restriction on the allowed sizes of allocated blocks. Allocated memory may be slightly larger than requested memory; this size difference is memory internal to a partition, but not being used
