1). Which one of the following is a shared peripheral device? 

A. Keyboard 

B. Flash Disk 

C. Mouse 

D. Monitor

💡

A shared peripheral device is a device that can be used by multiple users or computers simultaneously. Among the options provided, the correct answer would be:

A. Keyboard

Both a keyboard and a mouse can be considered shared peripheral devices as they can be connected to a computer or a device and used by multiple users. However, keyboards are typically shared more commonly than mice in scenarios such as computer labs or shared workstations. Flash disks (also known as USB flash drives) and monitors are not typically considered shared peripheral devices, as they are usually connected to individual computers or devices.

2). Which of the following is a key feature that describes proprietary software?

A. Software continually evolving 

B. Regular updates available 

C. No vendor lock-in

D. Source code open to the public 

💡

The correct answer is D. Source code open to the public.

Proprietary software refers to software that is owned by a specific individual or organization, and its source code is not freely available to the public. This means that the inner workings of the software, including its code, are kept confidential and not accessible for modification or redistribution by users. Proprietary software is typically distributed under specific licensing agreements that limit user rights and may impose restrictions on how the software can be used or modified.

The other options mentioned:

A. Software continually evolving: While proprietary software can indeed undergo updates and evolve over time, this is not an exclusive feature of proprietary software. Open-source software, for example, can also be continually evolving through community contributions and updates.

B. Regular updates available: Similar to the previous option, regular updates are not exclusive to proprietary software. Both proprietary and open-source software can receive updates to improve functionality, fix bugs, and enhance security.

C. No vendor lock-in: Vendor lock-in refers to the situation where users become dependent on a specific vendor's products or services, making it difficult or costly to switch to an alternative. This feature does not describe proprietary software specifically but can be a consideration when evaluating different software solutions, regardless of their licensing model.
