 Scanner   Scanner is a device that optically scans images, printed text, handwriting or an object and converts it to a digital image. Commonly used in offices are variations of the desktop  flatbed scanner  where the document is placed on a glass window for scanning.  Hand-held scanners , where the device is moved by hand, have evolved from text scanning "wands" to 3D scanners used for industrial design, reverse engineering, test and measurement, orthotics, gaming and other applications. Mechanically driven scanners that move the document are typically used for large-format documents, where a flatbed design would be impractical. Modern scanners typically use a charge-coupled device (CCD) or a contact image sensor (CIS) as the image sensor, whereas  drum scanners , developed earlier and still used for the highest possible image quality, use a photomultiplier tube (PMT) as the image sensor.

    Printer   A  printer  is a  peripheral  machine which makes a persistent representation of graphics or text, usually on  paper .  While most output is human-readable, bar code printers are an example of an expanded use for printers.  The different types of printers include 3D printer, inkjet printer  laser printer, thermal printer The first computer printer designed was a mechanically driven apparatus by Charles Babbage for his difference engine in the 19th century; however, his mechanical printer design was not built until 2000. The first patented printing mechanism for applying a marking medium to a recording medium or more particularly, to an electrostatic inking apparatus and a method for electrostatically depositing in on controlled areas of a receiving medium was in 1962 by C.R Winston, Teletype, Corporation using continuous inkjet printing. The ink was a red stamp pad ink manufactured by Phillips Proce...

  Computer  💻 A  computer  is a  machine  that can be programmed to carry out  sequences  of  arithmetic  or  logical operations  automatically. Modern computers can perform generic sets of operations known as  programs . These programs enable computers to perform a wide range of tasks. A  computer system  is a "complete" computer that includes the  hardware ,  operating system  (main  software ), and  peripheral  equipment needed and used for "full" operation. This term may also refer to a group of computers that are linked and function together, such as a  computer network  or  computer cluster . A broad range of industrial and consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots an...
