We can’t dispense it, and maybe we can’t live without it. |The computer is one of the most important technologies ever invented. In this age, we use computers every day and in almost all our jobs. It makes our lives easier, for instance, it cuts short the time that we spend to execute our tasks. Also, it is more accurate to do calculations. The computer can be classified into many types depending on size, power, or purpose of use. There are three famous types that we might see every day: the laptop, desktop, and handheld.
First of all, the laptop is a type of personal computer which is a portable device. The size of it varies including small, medium, heavy, and light. Its components like a keyboard, mouse, and CPU (Central Processing Unit) are integrated with the main system itself. Also, the optical device like the CD-drive is internal. Besides, a laptop is not powered by electricity but by a battery most of the time. Therefore, we can use it even when the power is cut or when we are away from home where there is not electricity.
The desktop is another type of computer. It is designed to fit on the top of the desk. Its size is big and heavy, so it has to be stationary. Desktop model computers are broad and comfortable to use. We can find this type in internet cafés, computer labs in school, and offices. Their components are opposite laptop’s components. They are separated from the main system. The optical device is internal, and you can connect with any external optical device that you need. Furthermore, the desktop feeds on electricity. It doesn’t work without it. For that reason we need to use desktops where the electricity is. Also, it is not convenient to move the desktop from place to place.
The last type of computer is the handheld, or sometimes it is called the pocket PC. It is a portable device that is small enough to be held in one hand. Also, it is used as a phone, so it is light. The most popular handheld computers are designed to provide personal information manager functions, such as a calendar and an address book. The hardware component like keyboard is replaced with an electronic pen, and it doesn’t have any optical device, so it is incapable of running CDs. However, these pen-based devices rely on handwriting recognition technologies. Moreover, the handheld computer works by battery, and we can use it without relying on electricity.
Computers are very popular technology now. Most people use them every day in schools, houses, work, and hospitals. Laptops, desktops, and handheld computers are the most common, especially the laptop that is the most popular type of computer use. Maybe we find everyone in the family owns private one. In my opinion, our purchase of the appropriate computer depends on what we need and what we want depending on its size, its components, and its power source.

As a part of my Academic Presentations class, I went to several lectures at UCF. Those lectures can be found on the UCF website under the section of “Campus Events.” Some of the lectures are open to all the UCF students or even those who are not students, but there are some where you may need to sign up. For example, I am interested in the American point of view of Chinese culture, so I participated in a lecture held by UCF alumni, “A Highly Civilized Country--3000 Years of Inventing China.” The professor is a Chinese historian and has spent over 20 years in China to study the culture there.
The lecture lasted an hour and covered one third of the five-thousand-year Chinese history. He spoke at a pretty fast speed with a bunch of unfamiliar vocabulary words for me in politics and economics. Yet, his PowerPoint slides and some other visual aids like handouts helped me a lot to understand his lecture even better.
However, my favorite part of the lecture was when the audience asked him some questions about the new president’s attitude towards the two counties, the United States and China. It was a really lively talk. I felt that all the audience was involved in the lecture and enjoyed what he had said.
It was a good way to practice my listening because the speaker was not a teacher who taught English as a second language. In addition, I realized that English was actually a tool to understand the cultural in a different way. After the lecture, there were some snacks for the speaker and the audience, so they could continue the topic in a friendly environment. That was really a free meal!
Learning English at CMMS in the classrooms is not the only way to improve your English skill. Those native English speakers are just a few steps outside the classroom around the campus. That is the real place where the language is used, and to take part in the real world with using English is why we study English so hard here. Try to move out of the classroom and you will find more opportunities to improve your English!
American moral: Don’t count all your chickens before they are hatched.
Azerbaijan moral: Don’t say opp! Before jumping over a ditch (or hole), “opp!” is what you say before you jump over something.
The grasshopper saw that and he thought, “That idiot! We can sing some songs and dance awhile.”
And the whole time he spent laughing heartily, singing and dancing. Then all summer the grasshopper spent having a wonderful time while the ant continued working harder and harder.
When the winter arrived, while the ant was warm and well-fed, the grasshopper had neither shelter nor food and went to the ant’s house and asked, “Can I have some wheat or any food? Without it, I will starve.”
“You danced last summer,” said the ants in disgust. “You can continue to dance.” And they gave him no food. Then he died.
Moral: Work hard! Be sensible and responsible because there is a time to work and a time to play.
