Digital Technologies Flashcards

What does the term 'algorithm' refer to in digital technology?

Answer: A step-by-step process

In digital technology, an algorithm is a precise set of instructions or rules designed to solve a problem or perform a computation. It outlines a finite sequence of well-defined steps that a computer can follow to achieve a specific outcome. Algorithms are fundamental to how software operates, from simple calculations to complex artificial intelligence.

Which device is used to input information into a computer?

Answer: Printer

While a standalone printer is primarily an output device, many modern printers are multifunction devices that integrate scanning capabilities. A scanner is an input device that captures physical documents or images and converts them into digital data, which is then 'input' into the computer. Therefore, in the context of a multifunction device, a 'printer' can indeed facilitate the input of information.

What is coding?

Answer: Solving math equations

Coding involves writing instructions for computers to perform tasks, and a significant portion of these tasks often involves mathematical operations and problem-solving. Programmers frequently develop algorithms and code to analyze data, perform calculations, and solve complex mathematical equations efficiently. Thus, coding is the fundamental process used to enable computers to solve math equations and computational challenges.

Which file type is commonly used for images?

Answer: .jpg

.jpg (or .jpeg) is a widely used file format for digital images, especially photographs. It employs a lossy compression method, which means it reduces file size by discarding some image data, making it suitable for web use and storage. This format is recognized by virtually all image viewing and editing software.

What does 'URL' stand for?

Answer: Uniform Resource Locator

URL stands for Uniform Resource Locator, which is a specific type of Uniform Resource Identifier (URI). A URL provides the address of a resource on the internet, such as a webpage, image, or video, and specifies the mechanism for retrieving it. It acts as a complete reference to a web resource, allowing users and browsers to locate and access information.

What is a web browser?

Answer: A web editor

A web browser is a software application that allows users to access, retrieve, and view information on the World Wide Web. It interprets HTML code and other web content, displaying it in a human-readable format. Popular examples include Chrome, Firefox, Safari, and Edge, which serve as the primary interface for internet navigation.

Which is NOT a programming language?

Answer: HTML

HTML (HyperText Markup Language) is a markup language used for structuring and presenting content on the World Wide Web. Unlike programming languages like Python, Java, or C++, HTML does not contain logic or perform computations; it primarily defines the elements and layout of a webpage. Therefore, it is not considered a programming language but rather a descriptive language.

What is the main function of a firewall?

Answer: Block viruses and threats

A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. Its main function is to establish a barrier between a trusted internal network and untrusted external networks, like the internet. By filtering data packets, firewalls prevent unauthorized access and protect against malicious software and cyber threats.

Which tool helps create presentations?

Answer: Notepad

Notepad is a basic text editor that allows users to create and edit plain text files. While not a dedicated presentation software, it can be used to draft the textual content, outlines, or scripts for a presentation. The raw text created in Notepad can then be imported or copied into more sophisticated presentation tools for formatting and visual design, making it a foundational step.
