Each invention usually comes along with its own inventor; however, the Internet - one of the greatest discoveries of mankind in the 20th century has no single inventor. It first started in the United States more than 50 years ago, and it kept evolved through time. For decades, scientists had been using it to communicate and share data with others. Many scientists and researchers had developed the best way of sending information from one computer to another. The very first computer was located in a laboratory at University of California, and it was about the size of a small house. By the end of 1969, there were just four computers that were connected to the Government’s Computer Network, but the network grew steadily during the 1970s. By the end of the 1970s, a computer scientist named Vinton Cerf had developed a way for all of the computers on all of the world’s mini-networks to communicate with one another. The Internet had a significant changing in 1991. That year, a computer programmer named Tim Berners-Lee introduced the World Wide Web: a “web” of information that anyone on the Internet could retrieve. Since then, the Internet has changed in many ways. Most recently, social networking sites Facebook, Twitter, YouTube, Instagram etc have become a popular way for people of all ages to stay connected. Today, we use the Internet for almost everything, and it would be impossible for many people to imagine life without it.

Mỗi một phát minh thường đi kèm với người đã sáng tạo ra nó; tuy nhiên, mạng Internet – một trong những phát hiện vĩ đại nhất của loài người trong thế kỉ 20 lại không có một người phát minh riêng lẻ nào. Nó bắt đầu lần đầu tiên vào hơn 50 năm trước tại Hoa Kì, và nó luôn tiến hóa theo thời gian. Trong nhiều thập kỉ, các nhà khoa học đã sử dụng nó để giao tiếp và chia sẻ dữ liệu với nhau. Rất nhiều nhà khoa học và nhà nghiên cứu đã phát triển cách tốt nhất để gửi thông tin từ một máy vi tính này sang máy khác. Chiếc máy vi tính để bàn đầu tiên được đặt ở một phòng thí nghiệm tại Đại học California, và nó gần bằng kích thước của một căn nhà nhỏ. Vào cuối năm 1969, chỉ có duy nhất 4 chiếc máy vi tính được kết nối với Mạng lưới Vi tính Quốc gia, nhưng hệ thống này phát triển bền vững trong những năm 1970. Vào cuối thập niên 70, một nhà khoa học máy tính tên Vinton Cerf đã phát triển một cách để tất cả máy vi tính trong một mạng lưới nhỏ toàn cầu có thể giao tiếp với nhau. Mạng Internet có một thay đổi nổi bật vào năm 1991. Vào năm đó, một nhà lập trình vi tính có tên Tim Berners-Lee giới thiệu cụm từ Mạng lưới toàn cầu: một “mạng nhện” thông tin mà tất cả mọi người trên Internet đều có thể lấy được. Kể từ đó, mạng Internet đã thay đổi theo nhiều cách. Gần đây nhất, những trang mạng xã hội như Facebook, Twitter, Youtube, Instagram..v..v. đã và đang trở thành một cách thức phổ biến để người dân ở mọi lứa tuổi có thể liên kết với nhau. Ngày nay, chúng ta sử dụng mạng Internet cho hầu hết mọi việc, và nhiều người sẽ không thể nào tưởng tượng được cuộc sống không có nó.

The picture describes a terrible forest-fire. On the left corner of the picture,there is a fireman in the uniform for his job which is the red jacket with white- striped. He is trying to put off the fire with a water pipe on his hand and we can see the nervous and the precipitation on his face. Being not far from him, the fire is burning onto the air. The water pipes are every where on the grass.It can be said that a part of the forest has an extensive damage and all the firemans are trying to complete their work as soon as possible.
A tiger from the forest came out, saw a farmer plowing with an ox is under the field. Buffaloes painstakingly go step by step, sometimes a whip whipped the butt. The tiger was surprised too. By noon, open plow, near Buffalo Tiger went back to ask:
- Hey, look he's healthy, why did you let the beat so miserable?
Buffaloes answered softly into the ear Tiger:
- He is small, but who has the intellect, he sir!
Tiger does not understand, curiously asked:
- What is Wisdom? How is it?
Buffaloes do not know how to explain, had answered via tangerine:
- Wisdom is wisdom, but there is something else? Want to know, then ask him!
Tiger strolled back to the farmer and asked:
- Where his words of wisdom, let me see a little bit okay?
British farmer thought for a moment and then said:
- Wisdom me to stay home. Let me take him to see. Do you need, I'll give him a little.
Tiger heard, so happy.
British farmers attempted to go, to do what he remembered saying:
- But where I come from, he ate buffalo miss me?
Tiger unknown wondering how to answer, the farmer has to say:
- Or do you take the trouble to do forced temporarily into this tree for me is reassuring.
Tiger consent, farmer and he took a rope tied tightly tiger to a tree. Done straw substance he took around Tiger, on fire and shouted:
- My wisdom here! My wisdom here!
Buffaloes saw it like so, roll out the laughing cow, unfortunately maxillary hitting rocks, broken teeth do not have one available.
But after burning off the ropes, the new Tiger busted up running straight into the woods last dared not look back.
Since then, the tiger was born on his son also had long black stripes, which are traces of burn marks, while Buffalo is such that the teeth on both.
