All questions of Computer and its Components for Class 10 Exam

A set of data when represented in a more organized and meaningful manner is called information...

Components of computer hardware are all of these

Stands for "Video Graphics Array." It is the standard monitor or display interface used in most PCs. Therefore, if a monitor is VGA-compatible, it should work with most new computers. The VGA standard was originally developed by IBM in 1987 and allowed for a display resolution of 640x480 pixels.

Yes, that's why it's called hardware. The hard drive, keyboard, etc., are hardware.

Software is the part you can't see or touch (not really, anyway). Like Microsoft Word or Google Chrome.

Input Devices

Input devices are the devices that accept data and instructions from the user. They are used to input data and instructions into the computer system. Some examples of input devices are:

1. Keyboard: A keyboard is a device that is used to input data and instructions into the computer system. It has a set of keys that are used to input characters and commands.

2. Mouse: A mouse is a device that is used to input data and instructions into the computer system. It is used to move a pointer on the screen and select items.

3. Scanner: A scanner is a device that is used to input images and documents into the computer system. It converts the image into a digital format that can be stored on the computer.

4. Microphone: A microphone is a device that is used to input sound into the computer system. It is used to record audio and voice commands.

5. Webcam: A webcam is a device that is used to input video into the computer system. It is used to record videos and video conferences.

Conclusion

Input devices are essential components of a computer system. They allow users to input data and instructions into the computer system. Without input devices, it would be impossible to interact with the computer system.

The collection of unprocessed facts , figures and symbols is known as DATA .. but yaha DATA k Saath information BHI bhi hai option C mein which is wrong so correct answer is D ( Non of the above) .. agar aapke 4 options mein se ek option sirf data ka hota toh fir D option correct nhi hota .

Types of Softwares

There are two primary types of softwares which are categorized as follows:

1. Application Software
2. System Software

Application Software

Application software is designed to perform specific tasks for users. It is a type of software that is developed to meet the requirements of end-users. These types of softwares can be further classified into two categories:

a) General Purpose Software - These softwares are designed to cater to a wide range of applications, and users can customize them according to their needs. Examples of such software include Microsoft Office, Adobe Photoshop, and Internet browsers.

b) Tailor-Made Software - This type of software is designed for specific users or organizations to meet their specific needs. Such software is often developed by software development companies on a contract basis.

System Software

System software is a type of software that is responsible for managing the hardware resources of a computer system. It is designed to provide a platform for the execution of application software. The following are the types of system software:

a) Operating System - This software is responsible for managing the hardware resources of a computer system. It provides a platform for the execution of application software and also provides various services such as file management, memory management, and process management.

b) Utility Software - Utility software is designed to perform specific tasks related to the maintenance and management of a computer system. Examples of such software include antivirus software, disk defragmentation software, and backup software.

Conclusion

In conclusion, the two primary types of softwares are application software and system software. Application software is designed to perform specific tasks for end-users, while system software is responsible for managing the hardware resources of a computer system. Application software can be further classified into general-purpose software and tailor-made software, while system software can be classified into operating systems and utility software.

Later on High level language programming were introduced such as COBOL and FORTRAN. Magnetic core was used as primary storage. Second generation computer has faster input /output devices which thus brought improvement in the computer. 1) Transistors were used in place of vacuum tubes.

In the rest of the options they are but talking about the different types of computers based on their size. While in option B the types on the basis of functioning are being talked about.
Thus the correct answer is (B)
Upvote and lemme know if that helped:)

Floppy disk is a circular thin plastic jacket coated with magnetic material. It is covered with a hard plastic cover to protect this disk. It stores information magnetically on one or both sides. Therefore, the correct answer is option 'D'.

FireWire is a cabling technology for transferring data to and from digital devices at high speeds. It was developed by Apple Inc. in the late 1990s and is also known as IEEE 1394 or i.LINK. FireWire is designed to provide fast and reliable data transfer between devices such as computers, digital cameras, external hard drives, and audio/video equipment.

FireWire supports data transfer rates of up to 800 megabits per second (Mbps), which is significantly faster than other popular cabling technologies at the time, such as USB 2.0. This high-speed capability makes FireWire ideal for tasks that require large amounts of data to be transferred quickly, such as video editing or file backups.

FireWire uses a serial bus architecture, which means that data is transmitted in a single stream of bits. This allows for high-speed communication between devices without the need for parallel data transmission, which can be more complex and prone to errors. FireWire also supports hot-plugging, which means that devices can be connected and disconnected from the bus without having to power off or restart the computer.

One of the key features of FireWire is its ability to support peer-to-peer communication between devices. This means that devices connected via FireWire can communicate directly with each other without the need for a host computer to facilitate the data transfer. This feature is particularly useful in scenarios where multiple devices need to exchange data quickly and efficiently.

FireWire cables come in different connector types, including 4-pin, 6-pin, and 9-pin configurations. The 4-pin connector is commonly used for small devices like digital cameras, while the 6-pin and 9-pin connectors are used for larger devices like computers and external hard drives. FireWire cables are also capable of providing power to connected devices, eliminating the need for separate power adapters.

Overall, FireWire is a versatile and high-speed cabling technology that has found applications in a wide range of digital devices. Its fast data transfer rates, peer-to-peer communication capabilities, and hot-plugging support make it a popular choice for professionals and enthusiasts in various fields.
