Q1:Describe the field of Information Technology.
(Reiterate initial flashcards but expand on its usage)
IT plays a crucial role in various areas, including data management, communication, business operations, education, and healthcare. It enables efficient storage, retrieval, and organization of data, facilitates communication through emails, video conferencing, and social media, and streamlines business processes such as inventory management and customer relationship management.
Q1:Describe the field of Information Technology.
(Reiterate initial flashcards but expand on its limitations)
Despite its numerous benefits, IT also has limitations. Cybersecurity risks, such as data breaches, hacking, and cyberattacks, are significant concerns. Additionally, over-reliance on technology can lead to disruptions during system failures. The digital divide can exacerbate social inequalities, as not everyone has equal access to technology. Moreover, the rapid pace of technological advancement can render hardware and software outdated quickly, creating issues for users and organizations. Finally, implementing and maintaining IT systems can be expensive, particularly for small businesses.
Q1:Describe the field of Information Technology.
(Reiterate initial flashcards but expand on its differences in disciplines)
IT is related to several disciplines, each with its own focus and methodologies. Computing emphasizes the development of algorithms and software solutions, encompassing both theoretical foundations and practical applications. Computer Science studies algorithms, programming languages, and computation theory, often with a more academic orientation. Software Engineering concentrates on the design, development, and maintenance of software systems, prioritizing methodologies and project management. Computer Engineering integrates electrical engineering with computer science, focusing on hardware-software integration and system design. Information Systems, on the other hand, concentrates on the management and organizational aspects of IT, particularly how technology supports business processes and decision-making.
Information Technology is concerned with the use of computers and not their design.
Q2: Outline the history of Information Technology.
Historically, The first sighting of information technology can be seen via the attempts of cavemen inscribing words or images into a wall. This showed the method that historically, humans have always used I.T because it displayed a desire to retrieve, store or manipulate information. IT history also includes the evolution of computer hardware (categorized by size and processing ability), software, the Internet, and telecommunications.
Q2: Outline the history of Information Technology.
(Reiterate but expand on hardware)
In terms of hardware, the journey began in the 1940s with the development of the first generation of computers, such as the ENIAC, which utilized vacuum tubes and were large and expensive. The transition to the second generation in the 1950s introduced transistors, making computers smaller, faster, and more reliable. By the 1960s and 1970s, integrated circuits further reduced size and cost, leading to the rise of mini and mainframe computers. The fourth generation, starting in the 1970s, marked the advent of microprocessors, which led to the creation of personal computers (PCs) and made computing accessible to the general public.
Q2: Outline the history of Information Technology.
(Reiterate but expand on software)
In software, the evolution began with early programming languages developed in the 1950s, like FORTRAN and COBOL, which allowed programmers to create applications more efficiently. As the field matured, the development of operating systems, such as Unix and Windows, made computers user-friendly and capable of multitasking. The introduction of graphical user interfaces (GUIs) in the 1980s revolutionized how users interacted with computers, paving the way for widespread adoption of personal computing.
Q2: Outline the history of Information Technology.
(Reiterate but expand on the internet)
The internet has been a game-changer in the history of IT. Initially developed as ARPANET in the late 1960s to facilitate communication between military and academic institutions, the internet evolved throughout the 1980s and 1990s with the introduction of TCP/IP protocols. Tim Berners-Lee’s invention of the World Wide Web in 1989 made the internet accessible to everyone, enabling the use of web browsers and hyperlinks for navigation. This ushered in the era of e-commerce, social media, and online communication, transforming how people access information and interact with one another globally.
Q3:Distinguish between data, information, and knowledge.
Data: Data refers to raw, unprocessed facts and figures that have no context or meaning. For example, the numbers "25," "30," and "45" by themselves are just data points. They could represent anything—temperatures, ages, scores, etc.
Information: Information is data that has been processed, organized, or structured to provide context and meaning. An example of processed data would be "The temperatures recorded on three consecutive days were 25°C, 30°C, 45°C," this context turns the raw data into information that is useful for understanding temperature variations.
Knowledge: Knowledge is the application of information to make decisions or solve problems. It involves understanding the relationships between pieces of information and applying them effectively. For example, if a weather analyst observes that temperatures above 40°C typically lead to heat advisories, they can use this knowledge to inform the public about potential health risks when temperatures reach 45°C.
Q4:Discuss various types of information sources.
Types include traditional sources like people, books, and newspapers, as well as electronic sources like websites, databases, blogs, and social media. These can be primary or secondary.
Q5: Identify characteristics of information sources.
Availability: How easily accessible the source is.
Cost: Whether it’s free or requires a payment.
Currency: How up-to-date the information is.
Amount of detail: The level of depth provided.
Breadth of coverage: The range of topics covered.
Reliability: Trustworthiness of the source.
Format and medium: Whether it's in print, digital, or other formats.
Q6: Describe the criteria for selecting information sources.
Bias: Ensuring the source presents information objectively.
Accuracy: How factual and error-free the information is.
Cultural context: Relevance to the culture or region.
Completeness: Whether the source covers the necessary scope.
Currency: The recency of the information.
Refereed and unrefereed sources: Peer-reviewed vs. non-peer-reviewed content.
Q7: Differentiate between primary and secondary information sources.
Primary sources: Original materials (e.g., interviews, surveys, research data).
Secondary sources: Summaries or analyses of primary sources (e.g., textbooks, articles).
Q8: Explain the concept of information as a commodity.
A commodity is a basic, good or raw material that is interchangeable with other goods of the same type. Commodities are often the building blocks for more complex products and are typically traded on exchanges.
In the context of information, the term "information as a commodity" means that information can be treated as a valuable resource that can be bought, sold, or traded, similar to physical goods. For example, market research reports, data analytics, and proprietary software can all be considered commodities in the information economy.
Q9: Discuss the relevance of information quality to decision-making.
High-quality information is essential for effective decision-making because it directly impacts the accuracy and reliability of the choices made. When decision-makers have access to accurate information, they can confidently assess situations and anticipate potential outcomes.
