This is because the data transfer between the components of a computer is typically done through the data bus, which is a communication pathway that allows for the transfer of data between the CPU, memory, and other peripheral devices. The data bus acts as a central highway through which information is transmitted, allowing for efficient communication and coordination between different parts of the computer system.Rate this question:

Dintre următoarele dispozitive de stocare, cea mai mare viteză de acces la date o are dispozitivul:
- A.
CD
- B.
DVD
- C.
Hard disk
- D.
Memorie flash
Correct Answer
C. Hard diskExplanation
The hard disk has the highest data access speed among the given storage devices. This is because hard disks use magnetic storage technology, which allows for faster read and write operations compared to other devices like CDs, DVDs, and flash memory. Hard disks have spinning platters and read/write heads that can quickly access data from different locations on the disk. On the other hand, CDs and DVDs have slower access speeds because they rely on optical technology, while flash memory has limited access speed due to its architecture. Therefore, the hard disk is the correct answer for the device with the highest data access speed.Rate this question:
