I have grown up on a farm, but even in our rural area, I can see ways that technology is being integrated into all areas of life. Computers play a vital role in society, affecting us as much as TV, cars, and electricity. Computers are an important tool because they help us communicate more easily, increase our efficiency, and add convenience to our hectic lives.

To begin, computers have vastly improved daily communication. E-mail has revolutionized the way many people stay in touch. For example, by using e-mail I was able to send a photograph of me, playing football, to my grandmother living away from me. She was thrilled, and that evening she sent me an electronic greeting card with an interactive football game! Also, I can communicate instantly with other friends who are online. Also, my parents don’t get mad at me for tying up the phone to talk with my friends. On the computer, if you can type, you can chat.

Working on a computer helps me create professional-looking reports and letters. I am not a very neat person, so I depend on word processing to help make my work look neat. I can tell that my teachers like it when they don’t have to read my sloppy handwriting. Besides, writing a long essay or a report by hand is extremely tiring. Computers have been a real lifesaver in that department.

Another wonderful thing about computers is that they can help you get and stay organized. Many kids, adults, and organizations store a lot of information on the computer. I know that my parents keep their tax records on it. When tax time comes along, instead of having to sort through boxes of junk, they have everything they need at their fingertips because they stored it on the computer.

Finally, shopping on the Internet is another great benefit of having a computer. I’ve bought books, music CDs, and gifts on the Internet. It’s so much better than dragging myself around from store to store, lugging shopping bags, and waiting in long lines. Of course, my parents keep an eye on what I buy and how much it costs. They don’t let me shop on the Internet that much, but I love to do it when I can.

I think that computers are marvellous machines and that what they can do is only going to increase. I’ve described here only a few of the ways that computers make a huge difference to me, my family, and my friends right now. Just think about all the other ways computers help people and organizations around the world and about the other benefits they’ll bring in the future!

Essay on artificial intelligence for class 7.

Writing essays helps kids and students to enhance their language skills and gives them an opportunity to express their ideas in a non-verbal way. When kids practice essay writing tasks, they learn invaluable skills of framing information on a particular topic into meaningful, coherent paragraphs. This skill helps them in the long run, in various ways beyond their academics. We at Vedantu, bring you a collection of essays that will guide you in practicing correct essay writing techniques and also will provide you with relevant information on important essay topics. Here’s an easy essay on Artificial Intelligence for your perusal.

Artificial Intelligence 

AI is a field of study to make the smartest use of computers. It can be defined as the ability of the computer to think and learn. In the modern era, the recent growth in technology has totally changed the face of science and engineering. This change has helped people in reshaping their relationships with the surrounding people and accepting the new way of living. 

Artificial Intelligence is the ultimate future of the world. There are four basic categories of AI which are- reactive machines, limited memory, the theory of mind, and self-awareness. The machines which are purely on the reaction basis, neither use past experience nor form memories to determine their future actions. The best example of it is- the game of chess, Deep blue has even beaten up the world champion Garry Kasparov. Reactive machines are the machines which are capable of purely reaction; it is also having the power to memorize from past experiences. 

The researchers are engaged in evolving the next two categories. Let’s broadly examine those. Theory of mind level AI will be able to better understand the entities it is interacting with by discerning their needs, emotions, and other thinking powers. And the last Self-awareness AI, which, self explanatorily, is an AI that has evolved to be so akin to the human brain that it has developed self-awareness.

AI is the solution to minimize human errors. Moreover, it never gets tired or wears out easily. We use a new device named ‘Alexa’, it’s fun learning and enjoying while the speedy mobile works are done by ‘Siri’. The smart cars are developed with a smart call system, to track the exact location and nearby positions. The AI also has some medicinal applications, it's said that time and tide waits for none, the doctor uses the artificial machine intelligence in patient’s treatment. AI is an alternative in many human risk situations; great research scientists use AI in calculating the flood intensity where human safety is vulnerable. 

There are countless pros and cons of any system, even a coin has two sides; it's up to the user the way he makes use of it. But in actuality, AI improves our thinking ability and to reach the horizon, even it states new horizons for the growing individual and expands its reach beyond the ocean and space. Time evolves from using a hand-fan to using smartphones to switching on the fan from the bed itself. The people must accept the new technologies and innovate for better lives and the divination of the country. 

AI is unable to exhibit human emotions so there is no reason to expect the AI to be benevolent. Furthermore, it is neither pocket-friendly, it requires a huge cost as it is a complex machine, not only its installation cost but also the maintenance and repair cost is huge. The major drawback is its not learning with the growing experience, it performs the same task in the same way as the algorithm installed inside it. In a way, creativity is somewhere vanishing with its use. 

Artificial Intelligence Types

There are two types of Artificial Intelligence:

The Narrow AI also known as  Weak AI. This is AI that operates within a limited context and simulates human intelligence. Narrow AI focuses on performing a single task extremely well, operating under constraints and limitations than the most basic human intelligence. Google search, Alexa or Siri, image recognition softwares, self-driving cars etc. are all examples of narrow AI.  

Artificial General Intelligence  or AGI is also referred to as Strong AI is the type of AI we see in the movies. Remember the robots from the TV show Westworld or Data from Star Trek: The Next Generation? AGI, like humans, can apply their general intelligence to solve any problem.

There are many pros and cons to any system. In the end, it is about how one decides to use it. 

AI doesn’t come cheap though. It involves a huge one-time cost for installation and then a constant spend on the maintenance and repair cost. So far, AI hasn’t been able to show or understand human emotions so there is no reason to expect the AI to be either benevolent or badly behaved. The major drawback of AI is that it  performs the same task in the same way each time as per the algorithm installed inside it. Also, the overuse and overdependence on AI is causing creativity to vanish slowly and steadily. 

Conclusion:

In the end though, AI can improve our thinking ability and help us reach new horizons, explore our growth potential and expand our reach beyond the ocean and space. Human beings have evolved with time. They have gone from using a hand-held fan to using smartphones to switch the fan on from wherever in the house they are. So, new technologies and innovations improve lives and are important to the progress of the country.

Artificial intelligence is a wing of computer science that deals with machines learning human-like intelligence. Softwares is incorporated with the ability to recognize patterns, analyze the surroundings, by using predetermined search algorithms or rules, and work on decision making accordingly. In other words, with the help of artificial intelligence, machines with the power of thinking and working like humans are being developed. For example, ’Alexa’ performs various searches based on speech recognition, and Siri is another example of an AI machine that works on speech recognition. Some other AI machines have software for problem-solving, planning, and learning patterns as well. 

2. What are the 4 types of AI?

AI machines can be classified into 4 types, namely,

Reactive Machines: These are the simplest types of machines working on AI, which do not have the ability to form any memories or to use past experiences for decision making. Hence these AI machines are termed reactive machines.

Limited Memory: These machines are incorporated with the ability to look in past memories. For example, self-driving cars are pre-programmed with the traffic light patterns, lane numbers, and the turns on the road. Based on this limited memory, the self-driving cars male decisions like when to make a turn to reach the pre-programmed destination.

Theory of Mind: These AI machines will have the ability to learn and recognize behaviour of people surrounding them, based on search algorithms or pattern recognition models. 

Self-Awareness: This will be the ultimate class of AI machines, which will have the ability to understand as well as possess consciousness. These machines will be an upgraded version of the Theory of Mind machines. These machines will be programmed in a way that will understand, learn, and make decisions based on past experiences.

3.  Give examples of AI in today’s times?
