Free IT Bachelor's Degree in Information Technology MCQ Questions and Answers — Questions and Answers
Question 1: Which one of these was the first search engine ever developed for the internet?
- Altavista
- WAIS
- Archie (Correct answer)
Correct answer: Archie
Archie, short for 'archive,' was the first search engine for the internet, developed in 1990 by Alan Emtage, Bill Heelan, and J. Peter Deutsch. It indexed FTP sites, allowing users to search for specific files across interconnected networks. While not a web search engine in the modern sense (as the World Wide Web was just emerging), it was the pioneering tool for finding information online.
Question 2: Which of these languages is used to create programs like applets?
- BASIC
- COBOL
- C Language
- Java (Correct answer)
Correct answer: Java
Java is the programming language specifically designed to create applets, which are small applications that can be embedded into web pages and run within a web browser. Its 'write once, run anywhere' capability, achieved through the Java Virtual Machine (JVM), made it ideal for distributing interactive content across diverse computing environments. While applets are largely deprecated now, Java was the primary language for their development.
Question 3: Which of the following is a connectionless protocol example?
- Frame Relay
- TCP
- UDP (Correct answer)
- IPX/SPX
Correct answer: UDP
UDP (User Datagram Protocol) is a connectionless protocol, meaning it sends data packets without first establishing a connection with the recipient. It offers a fast but unreliable delivery service, as it doesn't guarantee delivery, order, or error checking. This makes UDP suitable for applications where speed is more critical than reliability, such as streaming media, online gaming, and DNS lookups.
Question 4: The Network Interface Card (NIC) is commonly used for ______.
- Programming
- Printing
- Connectivity (Correct answer)
- None of the above
Correct answer: Connectivity
A Network Interface Card (NIC) is a hardware component that allows a computer to connect to a network. It provides the physical and data link layer functions necessary for network communication, enabling the computer to send and receive data over a wired or wireless connection. Essentially, the NIC is the gateway for a device to achieve network connectivity.
Question 5: The term "Linux" represents an _____.
- Operating System (Correct answer)
- Browser
- Application
- Software
Correct answer: Operating System
Linux refers to a family of open-source Unix-like operating systems based on the Linux kernel. An operating system manages computer hardware and software resources, providing common services for computer programs. While 'Linux' technically refers to the kernel, it is commonly used to describe the entire operating system, including the kernel, system utilities, and graphical user interfaces.
Question 6: What combination of keys do you press to bring down all displays and open windows currently visible on the screen?
- CTRL+D
- Alt+M
- Shift+M
- Windows Key+D (Correct answer)
Correct answer: Windows Key+D
On Windows operating systems, pressing the 'Windows Key + D' keyboard shortcut quickly minimizes all open windows and displays the desktop. Pressing it again restores the windows to their previous state. This shortcut is a convenient way to quickly access desktop icons or view the background without manually minimizing each application.
Question 7: If you want to boot into Safe Mode on a Windows computer, what key do you need to press?
- F9
- F8 (Correct answer)
- F2
- F1
Correct answer: F8
On older Windows operating systems (like Windows XP, Vista, and 7), pressing the F8 key repeatedly during startup would bring up the Advanced Boot Options menu. This menu included the option to boot into Safe Mode, a diagnostic startup mode that loads only essential system programs and services. While newer Windows versions use different methods, F8 was the traditional key for this purpose.
