They are commonly used in various applications and programs to move through documents, web pages, spreadsheets, and other content.
48.
. एक किलोबाईट बराबर होता है?
Correct Answer
B. 1024 बाईट
Explanation
The correct answer is 1024 bytes. In computer science, the binary system is used to represent data. In this system, each digit is a bit, and 8 bits make up a byte. In the binary system, 2^10 (1024) is the closest number to 1000, so it is used as the standard for measuring data storage. Therefore, 1 kilobyte is equal to 1024 bytes, not 1000 bytes.
49.
. कौनसा प्रिटर कागज़ के ऊपर स्याही की फुहार को तेजी से छिड़कर डेटा को प्रिंट करता है?
Correct Answer
B. इंकजेट प्रिंटर
Explanation
Inkjet printers are known for their ability to quickly and accurately print data onto paper by propelling tiny droplets of ink onto the surface. This process allows for a fast and efficient printing of text and images. Laserjet printers, on the other hand, use a laser beam to transfer toner onto the paper, while dot-matrix printers use a series of pins to strike an ink ribbon against the paper. Drum printers are not commonly used for printing data onto paper. Therefore, the inkjet printer is the correct answer as it matches the given description.
