Professor Sanchez gave a lecture on transitors last Tuesday. First, he explained what are transistors. He said, that they are very small electronic devices used in telephones, automobiles radios and so on. He further explained that transitors control the flow of electric current in electronic equipment. He wanted to know which popular technological invention cannot operate without transistors. Most students agreed, it is the personal computer. Professor Sanchez then asked if the students know how do transitors function in computers. He said that the transitors were etched into tiny silicon microchips and that these transistors increase computer’s speed and data storage capacity. Then he asked the class when had transitors been invented. Sergei guessed that they were invented in 1947. The professor said that he is correct. Professor Sanchez then asked what was the importance of this invention. Many students answered that it is the beginning of the information age. At the end of the lecture, the professor assigned a paper on transistors. He requested that each student chooses a topic by next Monday. He suggested that the papers are typed.

Professor Sanchez gave a lecture on transistors last Tuesday. First, he explained what transistors are. He said that they are very small electronic devices used in telephones, automobiles, radios, and other electronic equipment. He further explained that transistors control the flow of electric current in these devices. He then questioned the students on which popular technological invention cannot operate without transistors. Most students agreed that it is the personal computer. Professor Sanchez then asked if the students knew how transistors function in computers. He explained that transistors are etched into tiny silicon microchips, and these transistors increase the computer's speed and storage capacity. He also asked the class when transistors were invented. Sergei guessed that they were invented in 1947, which the professor confirmed as correct. Professor Sanchez then asked about the significance of this invention. Many students answered that it marked the beginning of the information age. At the end of the lecture, the professor assigned a paper on transistors and requested that each student choose a topic by next Monday. He suggested that the papers should be typed.
