Network RSCIT Quiz In English
In this RSCIT – or Research Student Community in Information Technology – quiz, we'll be putting your knowledge of networking to the test, with reference to topics like input and output devices, computers and operating systems. Let's take a look.
Questions and Answers
- 1.
Which one is not an output device?
- A.
Printer
- B.
Monitor
- C.
Keyboard
- D.
Modem
Correct Answer
C. KeyboardExplanation
A keyboard is not an output device because it is used to input data into a computer, rather than displaying or producing any output. Output devices, on the other hand, are used to present or transmit information from a computer to the user or another device. Examples of output devices include printers, monitors, and modems, which respectively produce hard copies of documents, display visual information, and transmit data to other devices.Rate this question:

Which one works as an output and input device?
- A.
Modem
- B.
Scanner
- C.
Mouse
- D.
Monitor
Correct Answer
A. ModemExplanation
A modem can work as both an output and input device. It serves as an output device by converting digital signals from a computer into analog signals that can be transmitted over telephone lines. On the other hand, it acts as an input device by converting analog signals from telephone lines into digital signals that the computer can understand. Therefore, a modem is capable of both sending and receiving data, making it an output and input device.Rate this question:

- D.
A virus checking program
Correct Answer
B. An operating systemExplanation
An operating system is necessary for all computers as it is the software that manages and controls the computer's hardware and software resources. It provides a platform for other software applications to run and ensures that different components of the computer can communicate with each other. Without an operating system, a computer would not be able to perform basic functions or run any software programs. Therefore, it is an essential requirement for all computers.Rate this question:

The brain of the computer is called:
- A.
Random Access Memory or RAM
- B.
Central Processing Unit or CPU
- C.
Read Only Memory or ROM
- D.
BIOS
Correct Answer
B. Central Processing Unit or CPUExplanation
The brain of a computer is called the Central Processing Unit or CPU. The CPU is responsible for executing instructions and performing calculations, making it the most important component of a computer system. It controls all the other hardware components and processes data to produce the desired output. While RAM, ROM, and BIOS are all important parts of a computer, none of them serve as the "brain" or central control unit like the CPU does.Rate this question:

An operating system is:
- A.
Integrated software
- B.
CD-ROM software
- C.
Application software
- D.
System software
Correct Answer
D. System softwareExplanation
An operating system is classified as system software because it is responsible for managing the computer's hardware and software resources. It provides a platform for other software applications to run on and ensures that they can communicate with the hardware effectively. The operating system also handles tasks such as memory management, file management, and process scheduling. Unlike application software, which is designed for specific tasks or user needs, the operating system is essential for the overall functioning of the computer system.Rate this question:

One MB is equal to:
- A.
The amount of RAM in every computer
- B.
1 billion bytes
- C.
1024KB
- D.
1 thousand bytes
Correct Answer
C. 1024KBExplanation
The correct answer is 1024KB because in the binary system, 1 kilobyte (KB) is equal to 1024 bytes. Therefore, when converting to a higher unit, such as megabytes (MB), the value is multiplied by 1024. So, 1 MB is equal to 1024KB.Rate this question:

Correct Answer
C. Dots per inch (DPI)Explanation
The resolution of a monitor refers to the number of pixels that can be displayed on the screen. It is measured in dots per inch (DPI), which indicates the number of dots or pixels that can fit into one inch of the screen. A higher DPI means a higher resolution, resulting in a sharper and more detailed image. Megabits, Hz, and inches (diagonal) are not used to measure the resolution of a monitor.Rate this question:

Correct Answer
A. Random Access MemoryExplanation
RAM stands for Random Access Memory. It is a type of computer memory that allows data to be read from or written to in any order, regardless of the physical location of the data. This makes RAM a fast and efficient storage medium for temporary data that the computer needs to access quickly. Unlike other types of memory, such as hard drives or solid-state drives, RAM is volatile, meaning that its contents are lost when the computer is powered off or restarted.Rate this question:
-
- 24.
Which one of the following is volatile?
- A.
Ram
- B.
EEPROM
- C.
EPROM

Correct Answer
C. Magnetic TapeExplanation
A magnetic tape is a secondary storage device that follows the sequential mode of access. It stores data in a linear manner, allowing for sequential reading and writing operations. This makes it ideal for applications that require large amounts of data to be stored sequentially, such as backup systems or archival storage. Unlike magnetic disks or optical disks, which allow for random access to data, magnetic tapes must be accessed sequentially from the beginning to reach a specific piece of information. Therefore, the correct answer is Magnetic Tape.Rate this question:
