Multimedia is a technology which stores data as text, photo, animation, music, video, etc.
Today, almost every person is directly or indirectly affected by the Internet. The Internet is an interconnection between several computers of different types belonging to various networks all over the world. Later, the military allowed universities to join the network for sharing the hardware and software resources. The network grew bigger and bigger and gave birth to the present-day Internet.
Fill in the blanks to complete the statements. Justify the statements. While working with a computer we can read the information stored in its memory and perform other actions in While presenting pictures and videos about the works of scientists, we can use To draw graphs based on the quantitative information obtained in an experiment, one uses The first generation computers used to shut down because of A computer will not work unless While presenting pictures and videos about the works of scientists, we can use microsoft powerpoint.
To draw graphs based on the quantitative information obtained in an experiment, one uses microsoft excel. Answer the following questions. Explain the role and importance of information communication in science and technology.
Which application software in the computer system did you find useful while studying science, and how? How does a computer work? What precautions should be taken while using various types of software on the computer? Which are the various devices used in information communication?
How are they used in the context of science? With the help of internet, one can collect scientific information and also share them with the help of emails or other social networking sites. It provides information on almost every topic. Some experiments and concepts in science can be demonstrated effectively using simulations and animations.
Following are the application softwares which I find useful while learning science: i Calculator: It helps in verifying the calculations done in subjects like physics and chemistry. A computer has various parts. It is the heart and brain of the computer.
It consists of various smaller components such as motherboard, hard disk, random access memory RAM , etc. CPU stores and processes the data. It controls the working of all the parts of computer, such as keyboard, mouse, etc. Random access memory RAM is a part of the storage unit.
It does not perform any kind of data processing. The internal memory of a computer is of two types: - RAM Random Access Memory : This allows data items to be read or write as long as the power is supplied to the system. Input Devices There are certain devices that help in providing the information to the computer. Such devices are known as input devices. Some input devices are keyboard, mouse, scanner, bar code reader, etc.
A keyboard is used for entering information, while a mouse is a pointing device that is used for indicating and selecting the input. Output Devices Some devices help in displaying the result of the processed data, such devices are known as output devices.
A monitor is the main output device that displays the result. Display of a monitor is made of pixels. These are the small dots on the screen.
Most of the computer screens are capable of displaying 80 columns and 25 rows. Monitors displays the data in the form of numbers, alphabets, etc. Monitors are available in the markets in various sizes and quality. Otherwise, it is going to slow your computer.
While working on excel, keep the data in tabular form. Even, avoid using unnecessary space and special characters. In case of downloading a new software, make sure that the site is authenticated from where it is being downloaded. Some examples where these devices are used are: Weather analysis: Super computers help in analysing the weather conditions of a particular place and provide information about it.
Medicine: Computers help in performing surgeries. Using a spreadsheet, draw graphs between distance and time, using the information about the movements of Amar, Akbar and Anthony given in the table on page 4 , in the lesson on Laws of Motion. What precautions will you take while drawing the graph?
Precautions to be followed while drawing the graph: Keep the data in tabular form. Data should be entered sequentially. Avoid using unnecessary space and special characters. Explain the differences between the different generations of computers. How did science contribute to these developments? Initially, the changes made were limited to those made in hardware technology. However, now it includes both hardware and software developments. The table given below shows the five generations of computers:.
Using information communication technology, prepare powerpoint presentations on at least three topics in your textbook. Make a flowchart of the steps you used while making these presentations. Note : This is an activity based question. Kindly make three presentations of any three topics on your own.
Type the information you want to write on the slide. Which technical difficulties did you face while using the computer? What did you do to overcome them? Technical difficulties faced while using the computer and ways to overcome them are: Computer being too slow: If your computer hangs in between, or boots up in more than a couple of minutes, then be assured that there is some problem in its working.
If the hard drive is full, try to empty it by deleting the not so important files or storing them in another hard drive. If none of this works, call ISP and see if they can help.
It may also arise due to some mechanical problem. Computer clean-up guide should be followed to do so. Page No Question 1: Fill in the blanks to complete the statements. Answer: a. Question 2: Answer the following questions.
Question 3: Using a spreadsheet, draw graphs between distance and time, using the information about the movements of Amar, Akbar and Anthony given in the table on page 4 , in the lesson on Laws of Motion. Answer: Precautions to be followed while drawing the graph: Keep the data in tabular form.
Question 4: Explain the differences between the different generations of computers. Third Integrated circuit based These are not in use. Question 5: What devices will you use to share with others the knowledge that you have?
Question 6: Using information communication technology, prepare powerpoint presentations on at least three topics in your textbook. Answer: Note : This is an activity based question. Question 7: Which technical difficulties did you face while using the computer? Answer: Technical difficulties faced while using the computer and ways to overcome them are: Computer being too slow: If your computer hangs in between, or boots up in more than a couple of minutes, then be assured that there is some problem in its working.
A computer is any machine that can be programmed to carry out a set of algorithms and arithmetic instructions. In terms of construction, each of these main components are attached to the motherboard and then put into a protective case—resembling the clean, polished look most of us are accustomed to seeing. Sure, most computers have their own distinct design - and different brands of hardware installed - but the components listed above are standard across all computers. This is by no means intended to be an invitation to disassemble your computer, nor is it a set of instructions to do so. Without the proper knowledge, you can severely damage your computer, and importantly, doing so is unsafe.

Незачем настораживать Хейла, давать ему знать, что они идут. Почти уже спустившись, Стратмор остановился, нащупывая последнюю ступеньку. Когда он ее нашел, каблук его ботинка громко ударился о кафельную плитку пола. Сьюзан почувствовала, как напряглось все его тело. Они вступили в опасную зону: Хейл может быть где угодно. Вдали, за корпусом ТРАНСТЕКСТА, находилась их цель - Третий узел. Сьюзан молила Бога, чтобы Хейл по-прежнему был там, на полу, катаясь от боли, как побитая собака.
Когда он попытался обойти Стратмора, тот преградил ему дорогу. Лестничная площадка, на которой они стояли, была совсем крохотной. Они сцепились.
Так не пойдет! - рявкнул Стратмор, - Мне нужен ключ. - У меня нет никакого ключа. - Хватит врать! - крикнул Стратмор. - Где. Хейл сдавил горло Сьюзан.
Чепуха. Ты никогда не смог бы проникнуть в почту коммандера.
