Rajasthan Informatics Assistant Questions
Q : Integrated circuit is related to which generation of computer?
(A) first generation
(B) second generation
(C) third generation
(D) fourth generation
Correct Answer : C
Explanation :
Integrated circuits (ICs) were first introduced during the third generation of computers. The third generation of computers, which emerged in the 1960s, saw the development and widespread use of integrated circuits. These tiny electronic circuits contained multiple transistors, resistors, and capacitors on a single semiconductor chip. The use of integrated circuits significantly reduced the size of computers, increased their processing speed, and improved their reliability, marking a significant advancement in computer technology.
Plotter is an output device that prints _______ etc. on hard copy.
(A) chart
(B) Graph
(C) drawing
(D) all of the above
Correct Answer : D
Explanation :
A plotter is an output device that prints vector graphics on hard copy. Unlike printers, which are designed for raster graphics and text, plotters are specialized devices used to produce high-quality drawings, diagrams, and other vector-based illustrations. Plotters use pens or other drawing tools to create precise lines and shapes on paper, making them particularly useful for applications that require detailed and accurate graphical output, such as architectural and engineering designs.
________ is an output device that is used for TV Like displays the output on the screen and it is also called visual display unit.
(A) Printer
(B) monitor
(C) Plotter
(D) Projector
Correct Answer : B
Explanation :
An output device that is used for TV-like displays and shows the output on the screen is indeed called a monitor. It is also commonly referred to as a visual display unit (VDU). Monitors and VDUs are used to display visual information from computers and other electronic devices, allowing users to view text, images, videos, and other graphical content. They come in various types, including CRT (Cathode Ray Tube), LCD (Liquid Crystal Display), LED (Light Emitting Diode), and OLED (Organic Light Emitting Diode) monitors.
What is system software?
(A) the software of the system
(B) computer software
(C) a collection of programs designed to control and operate a computer, increasing its processing capacity
(D) none of these
Correct Answer : C
Explanation :
System software is a program designed to run a computer's hardware and applications and manage its resources, such as its memory, processors, and devices. It also provides a platform for running application software, and system software is typically bundled with a computer's operating system.
Which of the following memory has the least access time?
(A) cache memory
(B) Magnetic bubble memory
(C) Magnetic core memory
(D) random access memory
Correct Answer : A
Explanation :
Cache memory has the least access time among the options provided. Cache memory is a high-speed type of volatile computer memory that provides high-speed data storage and access to the processor. It is faster than main memory (RAM) because it is located on the CPU chip or very close to it and stores frequently accessed data and instructions. Accessing data from cache memory is much quicker compared to accessing it from RAM, making cache memory the fastest type of memory in terms of access time.
The data remains the same after saving the file and turning off the computer-
(A) in RAM
(B) in secondary storage
(C) in the motherboard
(D) in primary storage
Correct Answer : B
Explanation :
The data remains the same after saving the file and turning off the computer when it is stored in secondary storage. Secondary storage devices, such as hard drives, solid-state drives, and optical discs, are non-volatile storage media. This means that they retain data even when the power is turned off. Unlike volatile memory (such as RAM), which loses its content when the computer is powered down, data stored in secondary storage remains intact until it is intentionally deleted or modified.
The acronym of Reusable Optical Storage is-
(A) CD
(B) CD-RW
(C) DVD
(D) ROM
Correct Answer : D
Explanation :
Actually, the correct acronym for Reusable Optical Storage is not ROM. The correct acronym is ROS, which stands for Reusable Optical Storage. ROS refers to a technology that allows optical storage media, such as DVDs and CDs, to be rewritten or reused multiple times for data storage purposes.
What are the monitors that display the output as an adjustment of RGB radiation?
(A) monochrome monitor
(B) color monitor
(C) gray-scale monitor
(D) flat panel monitor
Correct Answer : B
Explanation :
a color monitor is a type of display that can adjust and display output by manipulating the Red, Green, and Blue (RGB) radiation. In a color monitor, pixels are made up of red, green, and blue sub-pixels, and by varying the intensity of these colors, a wide range of colors can be displayed on the screen. Adjusting the intensity of RGB radiation allows the monitor to display different colors and shades, providing a full spectrum of colors to the viewer. This technology is commonly used in computer monitors, television screens, and other displays to produce vibrant and accurate color representations.
In terms of Computer Networks, what does VPN stands for:
(A) vertical personal network
(B) Verbal Private News
(C) virtual private news
(D) virtual Private Network
Correct Answer : D
Explanation :
A Virtual Private Network (VPN) is a technology that allows users to create a secure and encrypted connection to another network over the internet. VPNs are commonly used to ensure privacy and security when browsing the internet, especially when using public Wi-Fi networks. VPNs create a private tunnel for data transmission, protecting users' online activities from surveillance, censorship, and potential cyber threats.
Built-in memory of computer is-
(A) ROM
(B) PROM
(C) EPROM
(D) RAM
Correct Answer : A
Explanation :
The built-in memory of a computer typically refers to RAM (Random Access Memory). RAM is a type of volatile memory that the computer uses to temporarily store data that is actively being used or processed. It provides fast access to the data the computer needs to perform tasks, and its content is erased when the computer is powered off.
