What is a Scanner? What is it used for?

The scanner, also known as an optical drive, is a computer hardware component used to read data from light-sensitive storage media or to write data onto these media. There are three main types of optical discs. Optical drives used in personal computers are classified as follows:

  • CD (compact disc)
  • DVD (digital versatile disc / multifunctional digital disc)
  • BluRay (blue laser technology disc)

CD-ROM / DVD-ROM drives can read data stored on CD / DVD media. It is also possible to write data onto writable and rewritable versions of these media.

      What types of Scanners are there?

      There are many types of scanners available. Among them are:

      • Scanners integrated into multifunction printers,
      • Scanners that only have the scanning function and are generally used for scanning A4-sized documents (flatbed),
      • Portable scanners, which can scan small-sized documents.

      Portable Scanners

      These are scanners that can quickly scan photos and small texts. They are smaller and cheaper than regular scanners and can be easily carried by hand. For this reason, they are very easy to use.

      Flatbed Scanners

      Flatbed scanners are similar to photocopy machines. The document to be scanned is placed on the glass surface of the scanner.

      Drum Scanners

      Drum scanners are highly advanced. They are used in desktop publishing and modern printing systems. These are frequently preferred for preparing images used in newspapers, magazines, and brochures.

      The name of this type of scanner comes from the transparent acrylic cylinder mounted on it, which is used to transfer written documents. One of the distinctive features of drum scanners is their ability to control the size of the interval and the size of the scanned copies.

      Other types of scanners:

      • Film scanners (for digitizing slides and negatives)
      • Multiple document scanners (ADF)
      • Single-page feed scanners (Sheetfeed)
      • Planetary scanners (for book scanning)
      • Robotic scanners (for book scanning)
