Short Answers
1. A computer is an electronic device, operating under the control of instructions stored in its own memory, that can accept data, process the data according to specified rules, produce results, and store the results for future use.
The information processing cycle is input, process, output, storage.


2. Prolonged or improper computer use can lead to injuries or disorders of the hands, wrists, elbows, eyes, neck, and back. Besides, computers usage can lead to another health risk, computer addiction .Computer addiction occurs when someone becomes obsessed with using a computer.

Computer manufacturing processes and computer waste are depleting natural resources and polluting the environment. When computers are discarded in landfills, they can release toxic materials and potentially
dangerous levels of lead, mercury, and flame retardants.



3. A Web application is a Web site that allows users to access and interact with software from any computer or device that is connected to the Internet.
Web 2.0 provide a means for users to share personal information, allow users to modify the Web site contents, and/or have software built into the site for users to access.

A computer’s size, speed, processing power, and price determine the category it best fits.



5. Many Web sites provide up-to-date medical, fitness, nutrition, or exercise information. These Web sites also maintain lists of doctors and dentists to help you find the one that suits your needs. They have chat rooms, so that you can talk to others diagnosed with similar conditions. Some Web sites even allow you to order prescriptions online.

Through telemedicine, health-care professionals in separate locations conduct live conferences on the computer. While telesurgery, also called remote surgery, a surgeon performs an operation on a patient who

Additional use of this blog

Since I am enrolling in university studies, I will use this blog as another means for submitting my tasks as well. However, I'll keep trying provide you another information as what I did in past.
Sorry for some inconveniences.
Cheers !!!

A come back cheers !!!

Hello guys, it has been 3 years since my last post (it's too long). Sorry for not giving more information about things there. In this 1 year period, I experienced a lot of new things and I changed from just a Junior High School to a University student. I am really delighted that I finally reach this level.

Currently, I am taking Computer Science in Bina Nusantara University. Fortunately, I am in the Smart Class. It is a class taught in English (around 90%). I think this feature is really important, because it is a great advantage to always hear, write, and speak foreign languages, especially English. That's why I decided to join this special class when invited.

Overall, study in BiNus is a great thing to do. You will face new materials that you never face before in Senior High School, but they will acquire your basic in your last level of study, so be sure to prepare well your basic, especially in logic and mathematics (for Computer Science future undergraduates). If you are interested enough to join this university, I will say, "Go and take it !" The reason is simple, BiNus University will not lose in competing with other universities. It has controlled, good rules, comfortable study environment, and supportive teams or groups for your either hard skills or soft skills.

OK guys, that's all for this time. Since I am still the fresh undergraduate, I am not able to share many experiences with you all about my life in BiNus University, but I will keep updating the latest news to you all regarding my study and facts about the great BiNus University.

Keep moving forward, look to the front, and reach your dreams !!!

How to Predict Tomorrow's Weather?

Hello. This time, I would like to share with you my tips to predict the weather of the next day. It's really easy. I saw these on the television.

Well, for not the wasting the time, let me tell you:

1. Take a look at the sunset around 5.30 pm.

2. If the colour of the sunray is red orangish, it means tomorrow's weather, may be, will be a sunny day.

3. If it's red yellownish, it means tomorrow's weather, may be, will be a rainy day.

That's an important thing you should know. This is just a prediction. It doesn't mean that it will 100% true, but according to my test, it's true percentage is around 80%.

Just try it. Thank you.
