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.

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.
