What does 'ICT' stand for?
Correct Answer
C. Information and Communication Technology
Explanation
ICT stands for Information and Communication Technology, encompassing all technologies that facilitate the processing, transfer, and exchange of information and communication services. This includes a broad array of tools and services such as the internet, wireless networks, cell phones, computers, software, middleware, video-conferencing, social networking, and other media applications and services. Understanding ICT is fundamental for navigating today's digital world, as it integrates essential technology systems that enhance communication and the processing of information across various sectors and platforms.
2.
Which device is primarily used for data input?
Correct Answer
C. Keyboard
Explanation
A keyboard is a device primarily used for data input into computers and other electronic devices. It translates the keystrokes into corresponding characters and commands that a computer can understand and act upon. Keyboards are essential for typing documents, entering commands, and navigating interfaces in virtually all computer systems. This tool is fundamental in both personal computing and managing complex tasks on servers and mainframes, making it an indispensable component of modern ICT environments.
3.
What is the main function of a browser?
Correct Answer
C. Access the internet
Explanation
A browser is a software application used to access and view websites and navigate the internet. Its main function is to retrieve content from the web, which it then displays on the user's device. This process involves sending requests to server sites via the Hypertext Transfer Protocol (HTTP) and then rendering the HTML content to present images, texts, and links on user screens. Browsers also provide tools to bookmark pages, keep the history of sites visited, and ensure security during internet sessions, making them crucial for everyday internet use.
4.
What does RAM stand for?
Correct Answer
B. Random Access Memory
Explanation
Random Access Memory (RAM) is a type of computer memory that is used to store data temporarily while a computer is running. RAM allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory. This means that programs can access data quickly and execute tasks efficiently, making RAM a critical component for improving system speed and performance. More RAM allows for more applications to run simultaneously and for data to be accessed quickly, which is vital for both basic and advanced computing needs.
5.
Which protocol is used to send emails?
Correct Answer
C. SMTP
Explanation
SMTP stands for Simple Mail Transfer Protocol. It is an internet standard protocol used by email servers to send and receive email messages. SMTP dictates how email messages are formatted, encoded, and transmitted between mail servers, and it also sets the guidelines for message queuing and error handling. By using SMTP, email services can ensure that messages are properly sent and received, which is critical for reliable communication in both personal and business environments.
6.
What is a URL?
Correct Answer
B. Uniform Resource Locator
Explanation
A URL, or Uniform Resource Locator, serves as the address for a resource on the internet. URLs are used to specify addresses on the World Wide Web. A URL works in conjunction with the Hypertext Transfer Protocol (HTTP) to define how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands. This makes URLs essential for directing users to the correct website, ensuring they can access the information they need efficiently.
7.
Which type of software protects against viruses?
Correct Answer
B. Antivirus
Explanation
Antivirus software is designed to detect, prevent, and take action to disarm or remove malicious software programs, such as viruses and worms. These programs can perform a variety of functions, including stealing or corrupting data, hijacking core computing functions, and spying on users' computer activity. Antivirus software uses a variety of strategies to combat these threats, including scanning files and directories for malware, and quarantining or deleting infected files. It is a critical tool for maintaining computer system integrity and protecting information.
8.
What is cloud computing?
Correct Answer
B. Storing data on the internet
Explanation
Cloud computing refers to the storing and accessing of data and programs over the internet instead of on a hard drive or local storage in a computer. This technology allows for powerful servers to host software, platforms, and databases remotely, while users can access the services on demand using the internet. The scalability, reliability, and efficiency of cloud computing make it a cornerstone of modern IT strategies, enabling users and businesses to access a vast array of resources and services that can be scaled according to their needs.
9.
What does 'HTTP' stand for?
Correct Answer
A. HyperText Transfer Protocol
Explanation
HTTP stands for Hypertext Transfer Protocol. It is the foundation of data communication for the World Wide Web, dictating how messages are formatted and transmitted, and how web servers and browsers should respond to various commands. When you enter a URL in your browser, this actually sends an HTTP command to the web server directing it to fetch and transmit the requested web page. HTTP is an application protocol that forms the basis of data communication in the internet world, making it indispensable for browsing the web.
10.
Which is an example of an operating system?
Correct Answer
C. Windows
Explanation
Windows is an example of an operating system, which is software that manages computer hardware and software resources and provides common services for computer programs. An operating system is essential for the functioning of these programs since it acts as an intermediary between applications and the computer hardware. Windows provides a graphical user interface where users can access files, run software, play games, watch videos, and perform other activities. Other examples of operating systems include macOS, Linux, and Android, each with unique features but essentially performing the same critical functions.
