Answer:
The answer is "Option d'.
Explanation:
The database provides a single graphical view of the data, but it provides the facility to use logical view concept, that uses by view command, that uses the dataset to provide a logical view, that shows data according to user condition, and certain options were incorrect which can be described as follows:
computer programs and documents”
Answer:
"Backup Drive"
Explanation:
Stress results from outside stimuli. Option A is correct.
Cortisol has been identified as a stress-inducing hormone in studies of hormones in the human body.
Cushing syndrome is a condition characterized by elevated cortisol levels. This disorder is caused by your body producing too much cortisol.
Similar symptoms can occur after large doses of corticosteroids, thus this should be cleared out before testing for crushing syndrome. Stimuli from the outside cause stress.
Hence option A is correct.

The history of computer concepts can be divided into several distinct eras, each marked by significant technological advancements and shifts in computing paradigms. Here's a brief differentiation between historical eras and the current era of technology:
1. **Pre-Mechanical Era:** This era dates back to ancient times when abacuses and other simple counting tools were used for basic calculations. There was no digital technology during this period.
2. **Mechanical Era (19th century):** This era saw the development of mechanical calculators like Charles Babbage's Analytical Engine and the punched card system used for data processing.
3. **Electromechanical Era (1930s-1940s):** The invention of machines like the Turing Machine and the use of electromechanical devices marked this era, which laid the foundation for modern computing.
4. **First-Generation Computers (1940s-1950s):** Electronic computers such as ENIAC and UNIVAC were built during this period, using vacuum tubes and punch cards for data processing.
5. **Second-Generation Computers (1950s-1960s):** Transistors replaced vacuum tubes, leading to smaller and more reliable computers. High-level programming languages like Fortran and COBOL were developed.
6. **Third-Generation Computers (1960s-1970s):** The introduction of integrated circuits (ICs) led to even smaller and more powerful computers. Time-sharing systems and the development of ARPANET (precursor to the internet) were notable advancements.
7. **Fourth-Generation Computers (1970s-Present):** Microprocessors and personal computers became mainstream. The development of GUIs (Graphical User Interfaces) like the Macintosh and Windows made computing more accessible.
8. **The Internet Era (Late 20th century-Now):** The internet revolutionized communication and data sharing. The World Wide Web, invented by Tim Berners-Lee, became accessible to the public, leading to the modern internet era.
9. **Mobile and Smartphone Era (2000s-Present):** The rise of mobile devices, especially smartphones, brought computing to the palms of people's hands. Mobile apps and mobile internet usage became dominant.
10. **Cloud Computing and Big Data Era (2000s-Present):** Cloud computing services like AWS and Azure transformed how businesses manage and store data. Big Data analytics and machine learning became central to various industries.
11. **AI and Automation Era (2010s-Present):** Advances in artificial intelligence, machine learning, and automation technologies have had a profound impact on industries ranging from healthcare to finance.
12. **IoT and Smart Devices Era (2010s-Present):** The Internet of Things (IoT) has connected everyday objects to the internet, leading to smart homes, wearable devices, and more interconnected systems.
13. **Quantum Computing and Emerging Technologies (Ongoing):** Quantum computing, nanotechnology, and other emerging technologies hold the promise of transforming computing once again, with the potential to solve complex problems more efficiently.
In summary, the history of computer concepts has seen a continuous evolution from mechanical devices to the current era of interconnected, smart, and highly advanced computing technologies that are shaping various aspects of our lives. Each era has built upon the innovations of the previous one, leading to the rapid progress and digital transformation we witness today.
The history of computer concepts started with large, expensive machines that utilized punch cards for data input. The invention of the microprocessor led to personal computers, and later the internet further revolutionized computing. Today, computers are an integral part of life, with cloud computing, virtualization, and machine learning being prevalent.
The history of computer concepts is significantly different compared to today's era of technology. Initially, computers were large, expensive devices that were primarily used by businesses and government organizations. They used punch cards for data input and output was done using printers. However, with the advent of the microprocessor in the 1970s, personal computers became a reality. This led to a transformation in the computer technology landscape, making computers more accessible to the public. Later, the invention of the internet and the World Wide Web revolutionized how computers are used. Today, computers have become an essential part of daily life. We use them in the form of smartphones, laptops, tablets, and more. There is an increasing trend towards cloud computing, virtualization, and the use of AI and machine learning in computing. This demonstrates how far we have progressed from the early days of computing to the current era of technology.
