Answer: Option D. -> printer

Answer: Option B. -> stores
Storing is the process of retaining data or information in a computer system. It is one of the four basic operations of a computer system, which include input, output, processing, and storing. Data or information stored in the computer system can be used at any time and in any form.

Storing Data:
• Storing of data or information is one of the major operations of a computer system.
• Data or information is stored in the computer memory for later use.
• Storing of data can be done in two ways- temporary memory or permanent memory.
• Temporary memory stores the data only for a short period of time and is usually used for the processing of the data.
• Permanent memory stores the data for longer periods of time and is used for storing the data for later use.
• Data stored in the computer memory can be retrieved at any time and used for further processing.
• Data stored in the computer memory can also be modified or deleted as per the user’s requirement.

Advantages of Storing Data:
• Storing of data enables the user to use the data whenever required.
• Data stored in the computer memory can be accessed by multiple users simultaneously.
• Data stored in the computer memory can be modified or deleted as per the user’s requirement.
• Data stored in the computer memory can be used for further processing.
• Data stored in the computer memory can be stored for longer periods of time.

Disadvantages of Storing Data:
• Data stored in the computer memory can be lost due to power failure.
• Data stored in the computer memory can be corrupted due to virus attack or physical damage to the system.
• Data stored in the computer memory can be accessed by unauthorized users.
• Data stored in the computer memory can be modified or deleted without the user’s knowledge.

Answer: Option A. -> personal computer

Answer: Option D. -> mouse
The most common pointing input device is the mouse. A mouse is a handheld device that is used to control the movement of a cursor on a computer screen. It has two or more buttons that can be used to select or interact with objects on the screen.
The mouse works by tracking its movement on a flat surface, usually a mouse pad or desk, and transmitting that information to the computer. The computer then translates that movement into the movement of the cursor on the screen. The two main types of mice are optical and mechanical. Optical mice use a light-emitting diode (LED) to track movement, while mechanical mice use a rolling ball and internal sensors.
Advantages of using a mouse:

• Provides more precise movement control than other pointing devices like touchscreens or touchpads.
• It allows for faster and more efficient interaction with the computer than using only keyboard commands.
• The mouse can perform a wide range of functions beyond just pointing and clicking, including scrolling, zooming, and dragging.

Disadvantages of using a mouse:

• A mouse requires a flat surface to operate, so it may not be as portable as other devices.
• The mouse can be less intuitive for some users, particularly those who are not familiar with using computers.

In conclusion, the most common pointing input device is the mouse, which is a handheld device that tracks movement on a flat surface and is used to control the movement of a cursor on a computer screen. It provides more precise movement control and a wider range of functions than other pointing devices, but may not be as intuitive for some users.

Answer: Option A. -> Freeware

Answer: Option B. -> peripherals

Answer: Option D. -> Interpreter 

Answer: Option D. -> Supercomputer

Answer: Option B. -> motherboard

Answer: Option E. -> user friendly
User friendly is a term used to describe a product or technology that a user can interact with easily and effectively. The product or technology should be intuitive and require minimal instruction to use. It should also be responsive to user input, provide feedback, and be visually appealing.

User friendly is an important concept in human-computer interaction (HCI), a field of study focused on the design of user interfaces for computer systems and applications. A user friendly interface should be designed with the user in mind, so that it is easy and intuitive to use.

Definition: User Friendly is a term used to describe a product or technology that a user can interact with easily and effectively.

User friendly design is a key element of successful user experience, as it encourages users to interact with a product and increases the likelihood of them using it again. A user friendly design should have elements such as:

• Easy-to-understand language: The language used in the interface should be clear and concise, avoiding jargon and technical terms wherever possible.

• Logical flow: The user should be able to move through the interface in a logical manner, with clear options and directions at every step.

• Consistent design: Consistent design elements should be used throughout the interface, such as buttons, icons, and labels, so that the user can quickly recognize them.

• Responsive feedback: The interface should provide feedback to the user, such as displaying messages or changing the appearance of elements, to let them know what is happening.

• Visual appeal: The interface should be visually appealing, with an attractive layout, colour scheme, and use of images and graphics.

In summary, user friendly is a term used to describe a product or technology that a user can interact with easily and effectively. It is an important concept in human-computer interaction and user experience design, as it encourages users to interact with a product and increases the likelihood of them using it again.
