What are the largest memories of a PC?

For RAM, what characteristic can I change?

Why does the hard drive slow down when writing or reading in the paging file?

  1. why does the fragmentation of large files occur into smaller files, arranged on different tracks? the read head then slows down when reading these scattered fragments in memory.
  2. why is the speed of the disk used and not that of the ram?
  3. because it behaves like a ram but is used only when the latter is full and there is too much information. as a result, the computer slows down
  4. saturated with information
  5. because the information is temporarily saved on the hard drive and therefore takes up space on the hard disk.
  6. because it means that it is fully utilizing the ram but to avoid a crash it relies on the cache
  7. for file defragmentation
  8. for the latency time

Which memory costs the least?

What does the rotational speed of a hard drive depend on?

  1. A
  2. from the sum of the seek time, the rotational latency time, and the transfer time.
  3. from the diameter: the larger it is, the lower the speed will be
  4. from the ray
  5. time seek, rotation time, and transfer time
  6. from the diameter of the disc, it is calculated in rpm.
  7. it depends on the size of the disk; a disk with a larger capacity and therefore a larger surface area has a lower rotation speed.
  8. it is inversely proportional to the radius of the disk (therefore to its size)
  9. ray
  10. from the diameter of the disk

Why are serial connections faster?

  1. because the bits travel one after the other, without the electric and magnetic fields interfering with each other.
  2. because the movement of charges is not hindered by the interference of the magnetic field
  3. there is no interference from the electromagnetic fields of moving electrons
  4. there are fewer interferences
  5. because they create less interference
  6. because electrons travel in series, that is, one behind the other, and in this way the interference created by the electric and magnetic fields perpendicular to the path is reduced.
  7. because they interfere less with magnetic and electric fields, so electrons move faster.
  8. less interference is created between the magnetic fields
  9. because no interference is created due to the magnetic fields induced by the flow of current
  10. because they create less electromagnetic interference compared to parallel ones

What are the best features of an SSD?

What does formatting mean?

  1. restore to factory settings
  2. start writing information onto a blank hard drive, creating tracks, sectors, and clusters on each disk.
  3. create tracks and clusters on a memory
  4. incide tracks, clusters, and sectors on a blank disk
  5. to save
  6. etching process of the tracks
  7. formatting is the process that allows the first file to be saved on the hard drive (or ssd).
  8. formatting occurs when the hard disk head first touches the disk and saves the first file.
  9. delete information
  10. write to a hard drive
