Only a few can pass this basic computer science quiz

1. Which file extension is commonly associated with a Microsoft Word document?

.txt

.doc

.pdf

.xlsx

Microsoft Word, a widely used word processing application, utilizes distinct file extensions to denote its document formats. Traditionally, Word documents were associated with the file extension ".doc," signifying their format in earlier versions of the software. As Microsoft Word evolved, a more advanced and XML-based format was introduced, prompting the adoption of the ".docx" file extension for documents created in newer versions.

2. Main memory is also referred to as:

ALU

CU

CPU

RAM

Main memory is also referred to as RAM (Random Access Memory). It is the term commonly used to describe the computer's main volatile memory, where data and programs are temporarily stored while the computer is in operation.

3. Which keyboard shortcut is commonly used to "copy" selected text or files in most computer applications?

Ctrl + V

Alt + C

Ctrl + C

Shift + X

The keyboard shortcut Ctrl + C is widely used to copy selected text, files, or other content in various computer applications. This action places the selected content in the clipboard, allowing you to paste it elsewhere using the Ctrl + V shortcut. Understanding common keyboard shortcuts enhances efficiency and productivity when working with computers.

4. Which of the following statements is true about ROM?

New data can be written to ROM.

H is non-volatile.

The contents are lost when the computer Is turned off.

It is volatile.

ROM stands for Read-Only Memory, which means that the data stored in ROM cannot be modified or written to once it is programmed during manufacturing. It is non-volatile, which means that the data remains intact even when the computer is turned off. This is in contrast to volatile memory, such as RAM, where data is lost when the power is turned off. Therefore, the statement "H is non-volatile" is true for ROM.

5. Typing two letters in the wrong order ls an example of:

Transposition errors

Data verification

Data type error

System error

Transposition errors refer to the act of typing two letters in the wrong order. This can occur when a person accidentally switches the positions of two adjacent letters while typing. It is a common mistake that can happen due to human error or typographical errors. Transposition errors can lead to incorrect spelling or inaccurate data entry, and they are often caught during data verification processes.

6. A graphical user interface usually consists of:

Pascal commands

Video clips

DOS commands

Icons

A graphical user interface usually consists of icons. Icons are small graphical representations that are used to represent files, folders, applications, and various functions within a graphical user interface. They provide a visual representation of different elements and allow users to interact with them by clicking or tapping on them. Icons are an essential component of graphical user interfaces as they make it easier for users to navigate and interact with the system.

7. What does the acronym "URL" stand for in the context of web browsing?

Uniform Resource Locator

Universal Reference Language

Unified Resource Link

Underlying Resource Listing

A URL, or Uniform Resource Locator, is a web address that specifies the location of a resource on the internet. It serves as a standardized way to identify and access various resources, such as websites, documents, or images. Understanding URLs is fundamental for navigating the web and accessing specific content online.

8. Which of the following is an appropriate application for a super computer?

Word processing

Weather forecasting

3D gaming d Payroll Processing

Payroll processing

Weather forecasting requires complex mathematical calculations and simulations that involve large amounts of data. Supercomputers are specifically designed to handle these types of tasks, as they have the capability to process and analyze massive amounts of data at incredibly high speeds. This makes them ideal for applications such as weather forecasting, where accurate and timely predictions are crucial. Word processing, 3D gaming, and payroll processing can be performed on regular computers or even smartphones, as they do not require the same level of computational power as weather forecasting.

9. If a file allows direct access. what does that mean?

The computer has read-only access to the file.

The computer can Immediately read any record in the file.

The file is printed out so you can read it directly.

You do not need a password to access the file.

If a file allows direct access, it means that the computer has read-only access to the file. This means that the computer can retrieve information from the file, but cannot make any changes or modifications to it. Direct access allows the computer to immediately read any record in the file, without the need for sequential searching or scanning through the entire file. It does not mean that the file is printed out or that no password is required to access it.

10. Which of these features is essential for a process control application?

Human-readable documents

Wi-Fi connectivity

Sensor input

Graphical interface

A process control application requires sensor input in order to monitor and control various parameters of a process. This input allows the application to gather real-time data and make necessary adjustments to ensure optimal performance. Human-readable documents may be helpful for documentation purposes, but they are not essential for the application itself. Wi-Fi connectivity and a graphical interface may enhance the functionality and user experience, but they are not essential features for the basic operation of a process control application.
