Correct Answer
B. SectorsExplanation
A hard disk is divided into tracks, which are concentric circles on the disk. Each track is further subdivided into sectors, which are pie-shaped sections on the track. Sectors are the smallest unit of storage on a hard disk and are used to store data. Clusters, on the other hand, are groups of sectors and are used by the file system to manage the allocation of data. Vectors are not related to the division of a hard disk. Heads, on the other hand, are the components of a hard disk that read and write data to the disk's surface.Rate this question:

The 34-pin connection on an I/O card is for?
- A.
Floppy drive
- B.
SCSI drive
- C.
IDE drive
- D.
Zip drive
Correct Answer
A. Floppy driveExplanation
The 34-pin connection on an I/O card is for a floppy drive. Floppy drives use a 34-pin connector to connect to the I/O card, allowing data transfer between the drive and the computer. This connection was commonly used in older computer systems before the introduction of USB and other storage options. SCSI drives, IDE drives, and Zip drives typically use different types of connectors for connection to the I/O card.Rate this question:

Which standard govern parallel communications?
- A.
RS232
- B.
RS-232a
- C.
CAT 5
- D.
IEEE 1284
Correct Answer
D. IEEE 1284Explanation
IEEE 1284 is the correct answer because it is the standard that governs parallel communications. This standard specifies the electrical and mechanical interfaces for parallel communications between computers and peripheral devices, such as printers. It defines the signaling and data transfer protocols, as well as the physical connectors and cables used for parallel communication. RS232, RS-232a, and CAT 5 are not relevant to parallel communications and do not govern this type of communication.Rate this question:

Resistance is measured in ?
- A.
Volts
- B.
Amps
- C.
Watts
- D.
Ohms
Correct Answer
D. OhmsExplanation
Resistance is measured in ohms. Ohms is the unit of electrical resistance, which is the opposition to the flow of electric current. It is named after the German physicist Georg Simon Ohm. Resistance can be defined as the ratio of voltage to current in a circuit, and it determines how much current will flow through a given conductor for a given voltage. Therefore, ohms is the correct unit to measure resistance.Rate this question:

Which provides the fastest access to large video files?
- A.
Optical drives
- B.
IDE hard drives
- C.
SCSI hard drives
- D.
EIDE hard drives
Correct Answer
C. SCSI hard drivesExplanation
SCSI (Small Computer System Interface) hard drives provide the fastest access to large video files compared to the other options listed. SCSI technology allows for faster data transfer rates and lower latency, making it ideal for handling large files such as videos. Optical drives, IDE hard drives, and EIDE hard drives are relatively slower in terms of data transfer rates and access times compared to SCSI drives, which makes SCSI the preferred choice for accessing large video files quickly.Rate this question:
