Final answer:
Image Capture is the iMac application used for operating a scanner. It is different from applications like Grab, Bridge, or Finder features like Get Info and is built into Macs, eliminating the need for additional software to import images from scanners or cameras.
Step-by-step explanation:
The iMac application that you may use to operate a scanner is called Image Capture. This is a utility that comes pre-installed on Mac computers and allows for the importing of images from scanners and digital cameras directly into your Mac without the need for additional software. It's different from Grab, which is used for taking screenshots, and from Bridge, which is an Adobe application for organizing and browsing digital assets. Get Info is a Finder feature to show detailed information about files and applications, not for scanning purposes.
These days, many computers include built-in memory card readers, facilitating the transfer of photos from devices like digital cameras without the need for separate card readers or external devices. Additionally, some digital cameras come equipped with their own software to aid in downloading and managing images, much like iPhoto for Macs or Picasa for both Mac and Windows platforms.
