$\huge{\underline{\underline{\mathfrak{Answer}}}}$

➡️Sheetfed Scanners:-

Sheetfed scanners are smaller than flatbed scanners; as the name implies, you feed a document or photo into the scanner's automatic document feeder, or ADF, rather than place it on top of the platen one photo or document at a time.

➡️Portable Scanners:-

Portable scanners are small enough to bring on the road. In fact, some are small enough to put in your pocket; pen scanners are just a bit bigger than fountain pens and can scan the text of a document line by line. Some are as wide as a page and roll easily down the page.

➡️Flatbed Scanners:-

Flatbed scanners will take up some desktop space but provide a lot of bang for the buck. They look like miniature printers with a flip-up cover protecting the glass platen.

➡️Photo Scanners:-

Scanning documents doesn’t require high resolution or color depth, but scanning photos does. Many all-purpose scanners can also scan photos, meaning that you don’t need a separate device to handle your photographs
