Explanation:
The correct answer is option B, which is a Compact disc (CD).
A Compact disc (CD) is a flat and shiny circular device that is used for loading songs, movies, and games in a computer system.
Compact Disc (CD)
- A CD is a type of optical disc that is used for storing and playing digital audio, video, and other data.
- It has a diameter of 12 centimeters (4.7 inches) and is typically made of plastic.
- The surface of a CD is shiny and reflective, allowing it to store data in the form of microscopic pits and lands.

- CDs have a large storage capacity, typically ranging from 650 megabytes to 700 megabytes.
- This allows them to store a significant amount of data, including songs, movies, and games.
- CDs are widely used for distributing software, music albums, and movies.
- They are also commonly used for creating backups of important data.
Other Options:
a) Floppy disk:
- Floppy disks were used in the past for storing and transferring data.
- They are small and flexible, with a lower storage capacity compared to CDs.
- Floppy disks are no longer widely used due to their limited storage capacity and slow data transfer speeds.
c) Pocket drive:
- A pocket drive is a type of portable hard drive that is small and lightweight.
- It is used for storing and transferring large amounts of data.
- Pocket drives are typically connected to a computer via a USB or Thunderbolt port.
d) Hard disk:
- A hard disk is a non-volatile storage device that is used for storing and retrieving digital information.

**Explanation:**
A cursor control device is a hardware device that allows users to move the cursor on a computer screen. It is used to navigate and control the movement of the cursor, which is typically represented as an arrow or other graphical element on the screen. The cursor control device provides a way for users to interact with the computer and perform various actions such as selecting, clicking, dragging, and scrolling.
Out of the options provided, the correct answer is option 'C' - Trackball. Here's why:
**Trackball**
A trackball is a cursor control device that consists of a ball that can be rotated in any direction. It is usually located on the top of the device and can be operated by the user's fingers or palm. The movement of the ball translates into the movement of the cursor on the screen. By rolling the ball in different directions, the user can control the position of the cursor and perform various actions. Trackballs are commonly used in computer mice, where the ball replaces the traditional mouse wheel.
**Printer**
A printer is a device that produces a physical copy of digital text or images on paper. It does not control the movement of the cursor and is not considered a cursor control device.
**Scanner**
A scanner is a device that captures and converts physical documents or images into digital formats. It does not control the movement of the cursor and is not considered a cursor control device.
**Microphone**
A microphone is a device that converts sound into an electrical signal. It is used for recording audio or inputting sound into a computer. It does not control the movement of the cursor and is not considered a cursor control device.
In conclusion, out of the given options, a trackball is the only device that functions as a cursor control device. It allows users to control the movement of the cursor on a computer screen by rotating a ball.

Thumb keyboard is the type of keyboard that is used in smartphones.
Explanation:
Smartphones are designed to be compact and portable, and therefore require a keyboard that can be easily operated with one hand. The thumb keyboard is specifically designed for this purpose, allowing users to type using their thumbs while holding the device with one hand.
Features of a thumb keyboard:
- Compact size: Thumb keyboards have a smaller size compared to traditional keyboards, making them suitable for smartphones with limited screen space.
- Split layout: The keyboard is split into two halves, with each half placed on either side of the screen. This allows users to comfortably reach all the keys with their thumbs.
- Thumb-friendly key placement: The keys on a thumb keyboard are placed in a way that is optimized for easy access and typing with the thumbs. Commonly used keys such as the space bar, backspace, and shift keys are positioned within easy reach.
- Predictive text input: Many smartphones incorporate predictive text input features that can anticipate the word being typed based on the entered characters. This helps in increasing typing speed and accuracy.
- Touch sensitivity: Thumb keyboards are designed to be touch-sensitive, enabling users to tap on the screen to input characters. The keys are responsive to touch and provide tactile feedback to the user.
Advantages of thumb keyboards:
- One-handed operation: Thumb keyboards allow users to type with one hand, which is particularly useful when holding the smartphone in the other hand or when multitasking.
- Faster typing speed: With practice, users can achieve faster typing speeds on a thumb keyboard compared to other types of keyboards.
- Compact and portable: Thumb keyboards are lightweight and take up minimal space, making them ideal for smartphones.
In conclusion, the thumb keyboard is the type of keyboard used in smartphones due to its compact size, split layout, thumb-friendly key placement, touch sensitivity, and suitability for one-handed operation.
