1. The standard arrangement of alphabetic keys is known as ___________.

Explanation

The standard arrangement of alphabetic keys on a keyboard is known as QWERTY. This arrangement was named after the first six letters on the top row of the keyboard. It was designed to prevent the mechanical typewriter keys from jamming by placing commonly used letters apart from each other. The QWERTY layout has become the most widely used keyboard layout for typewriters and computers.

2. ___________ keys are used to input command without typing the long commands.

Explanation

Function keys are used to input commands without typing long commands. Function keys typically have specific predefined functions assigned to them, such as opening a specific program or performing a specific action. They provide a convenient way to execute commands quickly and efficiently, especially for tasks that are frequently performed. By pressing a single function key, users can execute a command without the need to type out the entire command, saving time and effort.

Submit
3. _________ scanner as used in stores, convert bar codes into digital signal.

Explanation

The given question is asking for the type of scanner used in stores to convert barcodes into a digital signal. The correct answer is "barcode" because barcode scanners are specifically designed to read barcodes and convert them into a digital signal that can be processed by a computer or point-of-sale system.

Submit
4. Cls command is used for________.

Explanation

The cls command is used to clear the screen in a command prompt or terminal window. It removes all the text and commands that were previously displayed, providing a clean and empty screen. This can be useful when the screen becomes cluttered with too much text or when starting a new task. By executing the cls command, the user can have a fresh start and a clear view of the command prompt or terminal.

Submit
5. ---------  can print only text.

Explanation

A daisy wheel printer can only print text. Daisy wheel printers were commonly used in the past and were known for their ability to produce high-quality text documents. The daisy wheel mechanism consisted of a disk with characters on its petals, and when a character was selected, the disk would rotate to the correct position and strike the paper, leaving an impression of the character. Unlike laser or LED printers, which can print both text and graphics, daisy wheel printers were limited to printing only text.

Submit
6. Who founded Apple computer?

Explanation

Steve Jobs is the correct answer because he co-founded Apple Inc. along with Steve Wozniak in 1976. He played a crucial role in the development and success of the company, overseeing the creation of iconic products like the iPhone, iPad, and Macintosh. Under his leadership, Apple became one of the most valuable and influential technology companies in the world.

Submit
7. _______ can be change during program execution.

Explanation

Variables can be changed during program execution, unlike constants which have fixed values that cannot be altered. A variable is a named storage location in a computer's memory that can hold different values at different times. This allows programmers to manipulate and update data as needed throughout the program. Therefore, the correct answer is Variable.

Submit
8. _____ is the performance of one program .

Explanation

The given question is incomplete and does not provide enough information to generate a clear explanation. It is unclear what is being referred to as "the performance of one program." Without further context, it is difficult to determine the correct answer.

Submit
9. Match the following
Submit
10. ASCII has ______ characters.

Explanation

ASCII (American Standard Code for Information Interchange) is a character encoding standard that represents text in computers and other devices. It uses a 7-bit code to represent a total of 128 characters, including letters, numbers, symbols, and control characters. However, with the addition of an eighth bit, ASCII extended to include an additional 128 characters, resulting in a total of 256 characters. Therefore, the correct answer is 256.

Submit
11. The 1's complement of 1010 is equal 0101

Explanation

The 1's complement of a binary number is obtained by flipping all the bits, i.e., changing 0s to 1s and 1s to 0s. In this case, the given binary number is 1010. When we flip the bits, we get 0101. Therefore, the statement "The 1's complement of 1010 is equal to 0101" is true.

Submit
12. Collection of 1024bytes?

Explanation

A collection of 1024 bytes is equal to 1 megabyte (1MB). In computer storage, data is measured in bytes, where 1 kilobyte (1KB) is equal to 1024 bytes, 1 megabyte (1MB) is equal to 1024 kilobytes, and 1 gigabyte (1GB) is equal to 1024 megabytes. Therefore, 1MB is the correct answer for the given question.

Submit
13. The amount of space between each pixel is called --------.

Explanation

Dot pitch refers to the amount of space between each pixel on a display screen. It is a measurement of the distance between the centers of two adjacent pixels and is typically expressed in millimeters. A smaller dot pitch indicates a higher pixel density and therefore a sharper image quality. Refresh rate refers to the number of times per second that a display updates its content, while resolution refers to the number of pixels in the display's width and height.

Submit
14. The function of trackball is same as joystick.

Explanation

The given statement is false. Although both trackballs and joysticks are input devices used for controlling movement on a computer screen, they function differently. A trackball is a stationary device where the user rolls a ball with their fingers to move the cursor, while a joystick is a handheld device that can be tilted or pushed in different directions to control movement. Therefore, the function of a trackball is not the same as a joystick.

Submit
15. Dot matrix printers can print up to- ----- cps.

Explanation

Dot matrix printers can print up to 400 characters per second (cps). This means that the printer is capable of printing 400 characters in one second, making it a relatively fast printing speed.

Submit
16. Plotter is used for general purpose printing.

Explanation

The statement is incorrect. A plotter is not used for general purpose printing. A plotter is a specialized output device that is used for producing high-quality, large-scale graphics such as architectural blueprints, engineering designs, and maps. It uses pens or markers to draw continuous lines on paper. General purpose printing, on the other hand, is typically done using printers that use ink or toner to create text and images on various types of paper.

Submit
17. --------- printers produce high quality text and graphics.

Explanation

Inkjet printers produce high quality text and graphics because they use small droplets of ink that are sprayed onto the paper. These droplets are very precise and can create sharp and detailed images. Additionally, inkjet printers can mix different colors of ink to create a wide range of colors, resulting in vibrant and accurate graphics. This makes inkjet printers a popular choice for printing photographs and other high-resolution images.

Submit
18. The ______ is the part of a floating point.

Explanation

The exponent is the part of a floating point number that represents the power to which the base (usually 2) is raised. It determines the scale or magnitude of the number. The exponent is responsible for shifting the decimal point and adjusting the value of the number. In scientific notation, the exponent is written as a superscript next to the base. In the context of the given question, the exponent is the correct answer as it specifically refers to the part of a floating point number.
