Computer Memory and Storage

Buffer memory temporarily stores data being transferred between devices of different speeds. The CPU quickly sends print output to the buffer, then immediately continues processing other tasks while the buffer slowly feeds data to the printer. This prevents CPU idle time.

Computer memory stores both data and programs (instructions). The CPU fetches program instructions from memory to execute operations. Bytes and bits are units of measurement, while registers are CPU components, not memory contents.

Bipolar semiconductor chips (using ECL or TTL logic) are fast but expensive and power-hungry, making them suitable for ALU operations where speed is critical. MOS (Metal-Oxide Semiconductor) technology is slower but much cheaper, allows high-density integration, and is ideal for large primary memory (RAM) storage. Silicon and Germanium are raw materials, not specific technologies.

IBM's PS/2 line used the newer 3.5 inch diskette format, which became the industry standard replacing the older 5.25 inch disks. The 3.5 inch diskette came in a rigid plastic case with a sliding metal shutter, offering better protection than the flexible 5.25 inch disks.

Option (2) is correct.

A sector is the smallest addressable unit on a hard disk, typically 512 bytes. Tracks are concentric circles, clusters are groups of sectors, making sectors the fundamental storage unit.

RAM (Random Access Memory) is a type of computer memory that stores data and machine code currently being used. It is volatile memory, not a file, network, or disk storage.

Hard sectored disks have sector markings physically encoded on the disk surface, fixing the number and position of sectors. Soft sectored disks determine sector boundaries magnetically during formatting, allowing more flexibility. The question asks for fixed sectors, which describes hard sectored disks.

1 YB = 1024^₈ bytes and is bigger than terabyte. But, it is the highest term in unit of Information measurement. So, this is the correct answer.

It is a dynamically updateable disk based index structure which implements a hashing scheme and grows or shrinks one bucket at a time.

Data stripping application of RAID technology takes data that needs to be stored, and distributes it evenly between two or more hard drives.

It is programmed at the manufacturing process. 

register variables are stored in register memory. register is a storage specifier used to enable faster access of a variable.

The statement is true about union. We can access only one member of union at a time because union allocates one common storage space for all its members.
