Computer Memory and Storage

Punched cards were used for data storage and input in early computing systems long before magnetic storage media like tapes or disks became standard.

Expanded memory (EMS) was a technique in DOS-based systems to access memory beyond the 640KB conventional limit by swapping pages into a small window, requiring specific software support.

Cache memory is a high-speed storage layer that holds frequently accessed data so that future requests for that data can be served faster than accessing the main memory.

Correct Answer: Bits

 A SODIMM or Small Outline Dual in-line memory module is the smallest version of the DIMM. Laptops and notebooks use this package.

SCSI (Small Computer System Interface) is a type of a hard disk drive and typically used in network server which includes lots of processing.

It is also referred to as bezel. The floppy disk is inserted in the floppy disk drive through this face plate.

The concentic rings known as tracks are required to store the data. The read/ write head moves over the required track and reads the data from the hard disk.

It is a 4 pin power connector which is used to connect to the hard disk drive.

 It is correct because this alphabet is placed on the face of the CD-RW drive. If the speed of the CD drive is specified as 12X, the transfer speed is 12*150 = 1,800kbps.

Partition Magic Pro is a system utility that enables you to create and re-size the drives without loss of information. Microsoft provides the basic utilities such as FDISK and FORMAT for disk management. These two utilities enable you to perform the basic tasks such as creating and formatting drives. But using these utilities, you cannot resize or undelete partitions.

We can make maximum 4 primary partions in a hard disk and minimum 1 primary parition where the window exists.

In early computer architecture terminology, the program area was typically the largest segment of memory allocated to hold the instructions for execution. Other areas like input, output, and working storage were smaller buffers or temporary workspaces.
