1. Scanners and cameras are input devices used to transfer images into a format that can be understood by computers.

Explanation: Scanners and cameras are electronic devices that allow us to capture and convert images (such as photographs, documents, or negatives) into digital data that a computer can process and interpret. They are classified as input devices because they input data into the computer system.

2. A scanner lets you copy photos and printed documents into your PC.

Explanation: A scanner is a specific type of device that allows you to make digital copies of photographs or printed documents by scanning them. When you place a photo or document on the scanner, it uses light and sensors to capture the image and convert it into a digital format that can be saved and accessed on a computer.

3. It has become one of life’s most familiar sounds – the beep of the supermarket till whenever a barcode is scanned.

Explanation: In a supermarket, electronic cash registers are equipped with a barcode scanner that can read the barcode of a product when it is scanned. The barcode contains information about the product, such as its price and description. When the barcode is scanned, it produces a beep sound to indicate that the product has been successfully recognized and added to the customer's bill.

4. If you need to scan 35mm film, you should go for a dedicated 35mm film scanner which concentrates all its dots into a tiny area.

Explanation: 35mm film refers to a specific type of photographic film used in traditional cameras. To digitally scan this film, a dedicated 35mm film scanner is recommended. This type of scanner is designed specifically for scanning 35mm film, ensuring that it captures all the details and dots of the film into a small area to produce high-quality digital images.

5. This scanner has a resolution of 300 x 500 dots.

Explanation: Resolution refers to the level of detail that a scanner can capture. It is measured in dots per inch (dpi). A higher resolution means more dots are captured, resulting in a clearer and more detailed image. In this case, the scanner has a resolution of 300 x 500 dots, indicating that it can capture a relatively high amount of detail.

6. A handheld scanner is small enough to hold in your hand.

Explanation: A handheld scanner is a portable and compact device that can be easily held and moved by hand. It is designed for convenience and mobility, allowing users to scan documents or images without the need for a large and stationary scanner. Handheld scanners are ideal for tasks that require scanning on-the-go or in limited spaces.

7. A document scanner is used to capture lines of text, barcodes, and numbers.

Explanation: A document scanner is a type of scanner specifically designed for capturing text-based documents such as letters, invoices, or forms. Unlike image scanners, which focus on capturing visual content, document scanners are optimized for capturing clear and precise lines of text, barcodes, and numbers found in various printed documents.

8. Most digital cameras use flash memory cards to store photos.

Explanation: Flash memory cards, also known as memory cards or storage cards, are small electronic devices used for storing data on digital cameras, smartphones, and other portable devices. Digital cameras, as mentioned in the question, use flash memory cards as the primary storage medium for the images and videos they capture. These cards come in various sizes and capacities, allowing photographers to store numerous photos before transferring them to a computer.

9. Flatbed scanners have a flat surface and take at least A4-sized documents.

Explanation: Flatbed scanners are a common type of desktop scanner characterized by their flat and open surface. They consist of a transparent glass plate where documents or images are placed for scanning. Flatbed scanners are versatile and can handle various sizes of documents, with the standard size being at least A4 (210 x 297 mm). They are commonly used in offices and homes for scanning documents, books, or delicate materials.

10. To scan photographic negatives or slides, you will need a film scanner.

Explanation: Photographic negatives and slides are special formats used in traditional film photography. To convert these formats into digital images, a film scanner is required. A film scanner is designed specifically for scanning negatives and slides, ensuring optimal image quality and capturing the unique characteristics of film-based photography. It allows photographers to preserve and digitize their film-based images for editing, sharing, or archiving purposes.
