Technology: Yesterday and Today

We are living in the 4.0 era, the era of developing technology, those things we feel are very normal, but in the past, things seemed impossible and beyond imagination. It's true that each other time. But with the past, there is the present, with the past, there is the present. And those who have gone through those old days will certainly feel more clearly the outstanding development of technology. 

1 Technology concept :

-Technology is the invention, change, use and knowledge of tools, machines, techniques, skills, systems, organizational methods, etc. Technology will solve a problem, improving an existing solution to achieve a goal or perform a specific function requires high levels of gray matter. Much influence on human ability to control and adapt. Simply put, technology is the application of scientific discoveries to practical and specific goals or products for human life, especially in the industrial or commercial field.

-Technology got its name from the Greek technologia with techno meaning craft and logia vó meaning maxim. The term refers to human tools and tricks, depending on the context of use:

• Tools and machines help people solve problems.

• Techniques include methods, materials, tools and processes for solving problems.

• The products created must be mass and similar.

• Products with high quality and low price.

 

2 What does technology include ?

-To learn more about it, we will go to learn about the core components that make up, those 4 components include:

• Engineering (T): includes machinery, equipment, core components that any technology must have. Humans will gain more muscle and intellectual strength in all activities thanks to the application of technology, especially production.

• Human (H): is the person who holds and controls technology including knowledge, experience, skills, etc. These factors help people operate machines and equipment and can use them in a way. optimal, most effective to create the required finished products.

• Information (I): information is data about techniques, people, organizations, etc., expressed in the form of data, stored in devices to serve human activities.

• Organizations (O): are units that apply technology, techniques and people to create common goals. The organization relies on people and technology, making full use of its strengths to achieve its goals.

3 The difference between past and present technology :

a .Telephone

In the past: After the advent of the digital dial phone, making calls on bulky desk phones became extremely simple.

Now: It's also effortless to make calls with ultra-thin smartphones. Smartphones also have the function of sending emails, taking photos, surfing the net, even searching for a life partner, planning relaxing activities… more easily. It must be admitted that our lives today are really revolving around the phone.

b Computers Ancient: The first computer that weighed about 30 tons and was as big as a building was considered a breakthrough invention at the time. Built to solve algorithms, computers can handle thousands of calculations per second.

Now: The personal computer weighs only about 2 kg so that users can carry it everywhere. Today, computers have many uses, not just a machine for simple calculations

c Camera

Ancient: To take a good photo it took at least 10 minutes to set up the camera and a day to process the film.

Now: In just 10 minutes you can take 500 photos you like and see them right away.

d Light bulb                                                                         

    In ancient times, people had to use fire to create a light source. From the 19th century, the method of using lamps became popular and then the incandescent light bulb of Thomas Edison. Today, we have fluorescent lamps and compact fluorescent lamps (CFLs). These technologies give more people access to light than in the past.

Thomas Edison

Now: By using LEDs, it is possible to limit the influence of polluting light sources. Due to their low power requirements, LEDs can be powered by inexpensive solar energy. In the future, if the cost of use becomes cheaper and cheaper, they can replace the fluorescent or incandescent lamps that are commonly used in Europe or the US.

e Computer

Old: In the 20s, industrial accounting machines could only do addition and subtraction.

Now: Mathematicians and engineers only need to use calculators to solve calculations.

F Television

- Ancient: With only 2 colors black - white or basic colors, the image displayed is quite monotonous and boring.

- Now: reproduce billions of brilliant colors with 4K IPS panels, Wide Color Gamut technology, 4K Hexa Chroma Drive Pro technology, Nano Crsytal technology,...

4.Application of technology?

Most areas of life today are applying technology, areas such as artificial intelligence, smart homes, or cleaning robots, maids, etc. are all products. from technology.-Abuse of technology is sometimes not good, but using technology in the right place in the right way helps to improve life, bring more convenience to people. Here are some areas of technology in action:

 -Industrialization and modernization:

Industrialization and modernization is the biggest change of modern technology that cannot be ignored. Automated production lines, machines and equipment are the best examples of this industry. They are used in life activities and production activities, increasing the value and quality of products. Reduce heavy work, reduce both resources and time.

 -Technology in social life:

The technology products that have contributed to the big change are smartphones, they help improve the way of studying, working, entertaining, etc., making life more diverse and unique. People easily grasp the information around, more active in life.

 -Automation system:

Technology gives us an important result – the automation system. The automation system can replace human labor, without affecting the quality of work.

5 Benefits of technology

-Benefits of digital technology

Technology has been appearing on all multimedia platforms and in all aspects of social life, helping to improve and enhance quality:

-Multi-tasking

Today, people do not need to sit at the office for 8 hours tired, thanks to digital technology. We can work anywhere and still be able to ensure work productivity is completed, connected to each other through anywhere with the Internet.

6 .Harm of information technology

Besides the advantages, the development of the information technology industry also has undesirable effects. Here are some of the harmful effects of technology as well as the harmful effects of the internet:

-Insomnia

Blue light emitted by mobile phones, tablets and laptops can prevent the development of melatonin in the body at night, helping to regulate the human circadian clock. When you use these devices too much, it will interrupt the process and make it impossible for you to go to sleep at a reasonable time.

This will negatively affect yourself as well as reduce concentration at work as well as problems with memory, or more seriously, it can even cause some brain tissue to die.

-Distracted, can't concentrate

-Memory loss

Human memory is divided into two types: short-term memory and long-term memory. Information that needs to be transferred from working memory into long-term memory can be stored. Any action in the working process such as talking, checking email, texting ... can also delete all that information before they are saved. Therefore, you should not do too many things at once on the internet.

-Forget faster, more

Working with computers a lot makes people sleep deprived, tired, leading to faster forgetting.

-Can not concentrate

Reading and learning online is very convenient, but it also has many limitations such as when you read an article surrounded by many advertising images, other articles with many different images and colors. This makes you quickly distracted and lose focus on what you are reading.

The scientific and technological revolution is happening on a larger, deeper and faster scale, seemingly at the same time on a global scale, to the point that the “shape” of tomorrow is unpredictable. . It expresses simultaneously, at the same time, resonance, mutation, surprise, intense influence, large scale and far-reaching compared to previous historical periods in the development of science and technology. and technology. There is a huge difference in the technology of the past and now, we are in an era of constant development.
