Direct access refers to the ability to retrieve data from any point in a storage device directly, without having to sequentially access preceding data. This is common in random access memory (RAM) and solid-state drives (SSDs). Serial access, on the other hand, requires data to be accessed sequentially in the order it was stored, such as in magnetic tape drives. This difference impacts the speed and efficiency of data retrieval in storage systems.
Depends, is the device serial or parallel?
Serial
ANSWERSecondary storage devices are not limited to USB pens. There are also, external hard drives, tape drives, jazz drives, scsi drives, cd's dvd's etc. These devices are primarily used for backing up any important data, which a user / company need.Also as a note to the previous answer, usb pens, vary widely in size from 128Mb up to now, i think its 8Gb. And I wouldn't be surprised if the 8gb limit is lifted even higher sooner or later.Answerthe secondary storage device are called usb(UNIVERSAL SERIAL BUS)this storage device will be able to carry out your data through usb and you will be able to open the same data without plgging out your memory card or your hardware "it depends on the capacity of the usb you may use 1gig or 2gig"
The advantages of using a serial console connection to a Cisco router or switch include direct access to the device for configuration and troubleshooting, even when network connectivity is unavailable. This method is also secure, as it requires physical access to the device. However, disadvantages include the limitation of distance, as serial connections typically require proximity to the device, and the need for physical cables and a terminal emulator, which can be cumbersome compared to remote access methods like SSH or Telnet. Additionally, it lacks the convenience of managing multiple devices simultaneously.
Dongles have a primary that they use for primary storage of data so that they can transfer it to the device it has been connected. And the primary storage has a partition that is specifically devoted to storage of some log files, serial codes, manufacturer's digital signatures and probably passwords.
The universal serial bus (USB) is a communication device, however it can communicate just about anything that the computer knows about. There are currently available many USB devices available to which the computer can send digital data for storage, including but not limited to: * USB memory sticks * USB disk drive adapters which convert the signals to/from an external disk drive to simple communication signals. * USB communication to cameras, then the computer just treats the camera as another disk drive. * USB audio devices. Songs are stored as digital files on the device. But USB devices are not limited to storage
It is not necessary to power down the computer to hook up a serial device. It is also not necessary to power down a serial device before hooking it up to a computer.
