Computers store and perform calculations using binary data, which consists of only two digits: 0 and 1. This is because computer hardware is designed to work with electronic switches that can be in one of two states: on or off. By representing data in binary form, computers can efficiently store and process large amounts of information using simple and reliable electronic circuits. Therefore, the correct answer is "बाइनरी" (binary).

The correct answer is सिस्टम यूनिट. In a computer system, the system unit refers to the main cabinet or chassis that houses the motherboard, CPU, memory, and other internal components. It is responsible for processing and storing data, and it is where all the essential hardware components of a computer are located. The other options, such as keyboard and monitor, are peripheral devices that connect to the system unit but are not considered part of it.

Iron oxide is the correct answer because it is a compound that is commonly found on magnetic disks. Iron oxide, also known as rust, is used as a magnetic coating on the surface of disks to store data magnetically. This coating allows the disk to be read and written to by a magnetic head, making it an essential component of magnetic storage devices like hard drives.

OCR का पूरा रूप "Optical Character Recognition" है। OCR एक प्रौद्योगिकी है जो इमेज या टेक्स्ट दस्तावेज़ को स्कैन करके उसमे मौजूद टेक्स्ट को डिजिटल रूप में परिवर्तित करती है। OCR का उपयोग विभिन्न क्षेत्रों में किया जाता है, जैसे कि डॉक्यूमेंटेशन, बैंकिंग, पुलिस, और लागू कानूनी क्षेत्र में। OCR टेक्स्ट को संग्रहीत करने, संपादित करने, और खोज करने के लिए उपयोगी होता है।

The correct answer is "Liquid Crystal Display". LCD stands for Liquid Crystal Display, which is a type of flat-panel display technology commonly used in electronic devices such as televisions, computer monitors, and smartphones. It uses a liquid crystal solution sandwiched between two transparent electrodes to create images.

The correct answer is "पोइंटिंग डिवाइस" because in Hindi, "ट्रैक बाल" refers to a pointing device, such as a trackball, which is used to move the cursor on a computer screen. "प्रोग्रामिंग डिवाइस" refers to a programming device, "आउटपुट डिवाइस" refers to an output device, and "सॉफ्टवेयर डिवाइस" refers to a software device, none of which are examples of "ट्रैक बाल".

The correct answer is "प्लोटर, प्रिंटर, मॉनिटर". These three devices are output devices that are used to display or produce information to the user. A plotter is a device that is used to produce high-quality graphics or drawings, a printer is used to produce hard copies of documents or images, and a monitor is used to display visual output from the computer. The other options in the question include input devices like a scanner, keyboard, and mouse, which are used to input data into the computer.

The correct answer is "बार कोड्स" because bar codes are printed lines that contain information about a product, which can be scanned using a barcode scanner.

The correct answer is "उपरोक्त सभी" which means "All of the above". This answer suggests that all of the mentioned options - floppy disk, tape-magnetic, and hard disk - are used for permanent memory in a computer.

The correct answer is multiprocessing. Multiprocessing refers to the use of multiple processors or cores in a computer system to execute multiple tasks or processes simultaneously. It allows for improved performance and efficiency by distributing the workload across multiple processors, enabling parallel processing. This is different from multiprogramming, which involves running multiple programs concurrently, multitasking, which involves running multiple tasks or processes concurrently, and time-sharing, which involves sharing the computing resources among multiple users or processes.

The correct answer is ROM BIOS. ROM BIOS stands for Read-Only Memory Basic Input/Output System. It is a type of firmware that is stored on a chip on the computer's motherboard. The ROM BIOS contains the instructions that are necessary for the computer to start up and initialize the hardware components. It is responsible for performing a power-on self-test (POST), detecting and configuring hardware devices, and loading the operating system from the boot device.

कोम्बिनेशन कीज का प्रयोग शॉर्टकट बनाने के लिए किया जाता है।

The correct answer is "पैराग्राफ इंडेंट करने के लिए". The Tab key is used to indent paragraphs in a document. By pressing the Tab key, the cursor moves a set distance to the right, creating an indentation at the beginning of a new paragraph. This helps in visually organizing the content and making it easier to read and understand.

When multiple tasks are given to a computer and they are processed one by one, it is called batch processing mode. In this mode, the computer executes each task in sequence without any interruption or interaction with the user. This mode is commonly used in situations where a large number of similar tasks need to be performed, such as processing a batch of files or running a batch script.
