Scan code in the context of a keyboard 2. Impact printer. Answer 1. Scan code in the context of a keyboard: In the context of a keyboard, a scan code refers to a unique identifier assigned to each key on a keyboard. When a key is pressed or released, the keyboard's hardware generates a scan code corresponding to that key. The scan code is then sent to the computer, which interprets it and performs the appropriate action, such as displaying the corresponding character on the screen or triggering a specific function associated with that key. Scan codes are typically standardized to ensure compatibility across different keyboards and computer systems. 2. Impact printer : An impact printer is a type of printer that creates printed output by physically striking an inked ribbon against the paper. These printers work by using

Also, explain the physical characteristics of magnetic disk. Answer The disk layout of a magnetic disk refers to the organization and structure of the data on the disk. Magnetic disks, such as hard disk drives (HDDs), consist of multiple platters stacked on a spindle. Each platter is coated with a magnetic material and is divided into concentric circles called tracks. These tracks are further divided into smaller units called sectors. The arrangement of tracks and sectors forms a grid-like pattern on the disk surface. The disk layout typically follows a cylindrical geometry, where corresponding tracks on each platter are aligned vertically. This arrangement allows the read/write heads to move across multiple platters simultaneously, improving data access speeds. The physical

Start the algorithm 2. Take the input number. 3. Check if the number is less than or equal to 1. 4. If the number is less than or equal to 1, it is not a prime number. 5. If the number is greater than 1, iterate from 2 to the square root of the number. 6. For each iteration, check if the number is divisible by the current iteration. 7. If the number is divisible by any iteration, it is not a prime number. 8.

Explain the von Neumann's architecture with the help of a diagram. Answer . Von Neumann architecture is a design concept for building digital computers that consists of several key components. The architecture was proposed by the mathematician and computer scientist John von Neumann in the late 1940s. It serves as the foundation for most modern computer systems.  Here is a simplified diagram illustrating the von Neumann architecture: Let's through each component : 1. ** Memory **: This is the storage area where both data and instructions are stored. It can be divided into two parts: the **data memory** for storing data and the **instruction memory** for storing program instructions. 2. ** Control Unit **: This component manages and coordinates the activities of other components in the computer.
