Input and output devices allow the computer system to interact with the outside world by moving data into and out of the system. An input device is used to bring data into the system.

In this lesson students consider a number of computing devices to determine what types of inputs and outputs they use. Groups are assigned to a computing device and based on a teacher-provided definition of input and output, list the inputs and outputs of their device. Earlier in the activity students are prompted to focus on more obvious physical inputs and outputs e.

Keyboard is the most common and very popular input device which helps to input data to the computer. The layout of the keyboard is like that of traditional typewriter, although there are some additional keys provided for performing additional functions. These keys include the letter keys A-Z and digit keys 09 which generally give the same layout as that of typewriters. It is used to enter the numeric data or cursor movement.

In this lesson students consider a number of computing devices to determine what types of inputs and outputs they use. Groups are assigned to a computing device and based on a teacher-provided definition of input and output, list the inputs and outputs of their device. Earlier in the activity students are prompted to focus on more obvious physical inputs and outputs e.

Throughout the lesson the teacher records inputs and outputs that are identified on a T-Chart at the front of the room. To conclude the lesson students examine common activities they do on a computing device and select the inputs and outputs used for that activity from the chart.

In the previous lesson students were introduced to the input, output, store, and process model of a computer. Since this model of a computer is still fairly abstract, this lesson grounds it in the ways a computer actually input and output information.

Discussion Goal. Goal: In today's lesson students will be talking about how to get "stuff" in and out of a computer. This discussion just aims to replace the word "stuff" with a more useful long-term vocabulary word of "information". It's fine if what that word means is still a little fuzzy at the end of the conversation.

Possible Responses: Photos, documents, videos, music, apps, games, spreadsheets, websites, etc. If need be you can jumpstart conversation by naming one or two of these and seeing if that helps students think about other examples. Prompt: In the last lesson we learned that a computer is a device that "processes information". That phrase is still a little vague, so let's see if we can clarify it a bit. What kinds of "stuff" do you use, look at, create, or edit on a computer that you think might actually be information?

Discuss: Students should brainstorm silently, then share in pairs, then discuss their ideas with the whole class. This conversation should be pretty open-ended. Great work, and I'm sure we could think of more examples if we tried. All the examples you just provided are the "information" that we use computers to process.

Today we're going to look at an important question of how this information gets in and out of the computer in the first place. Give them Physical Examples: This activity guide includes small photos of each category of device but students can and should look at actual computers if they're on hand. Depending on your classroom rules you might say this is one of the only days they should have their phones out in class!

Display: At the front of the room place a large poster or project a document where you will record all the inputs and outputs students brainstorm in this activity. Vocabulary: As a class review the two vocabulary words found on the top of the activity guide, input, and output. Inputs and Outputs - Desktop: Have students complete the first row of the activity guide by listing all of the possible inputs and outputs to a desktop. Encourage students to think about about the actual computer, as well as devices that they connect to one.

Discuss: Have students share the results of their brainstorm. As they share them record their answers on the poster at the front of the room. Inputs and Outputs - Laptop: Have students complete the second row of the activity guide by listing all of the possible inputs and outputs to a laptop. If it does not come up naturally prompt students about how they talk to people using other computers.

Call out that communicating over the Internet is a form of input and output. There are a lot more inputs and outputs on a smartphone than you students might think of right away.

If your students struggle here, consider asking them the following prompts:. Inputs and Outputs - Smartphone: Have students complete the final row of the activity guide by listing all of the inputs and outputs of a smartphone. In particular call attention to the fact that a screen now serves many roles as both the input and output of a smartphone. Some less obvious inputs may require you to provide examples to students.

For example, if a smartphone shows you where you are on a map then it must somehow know where you are. In other words there must be some kind of input a GPS system that provides that information. Similarly if a phone knows when it's been rotated then there must be some kind of input device that is detecting how a phone is positioned.

Goal: Use this wrap up activity to assess how well students have understood the role of input and output in some common activities on a computer. For example:. Prompt: Brainstorm three everyday activities you or people you know do with a computer.

Circulate: Have students brainstorm with their groups and record their ideas on their activity guides. Point students towards the list of inputs and outputs you've listed on the board. In this lesson you'll learn about the different types of input and output devices used by computers and the types of information they send and receive.

Computer input and output devices

To interact with a computer, you need an intermediary, something that receives data you input and translates it for your computer. This intermediary is an input device. Input devices for communication are those that let you send sounds, thoughts, images or files to others via the computer. For business, input devices let you reach out to customers, colleagues and vendors. Businesses sometimes have hard copies of documents or images at one location that someone at another location needs to see. Scanners can translate a hard copy into a digital file, which allows a connected computer to receive it. The file can then be uploaded or emailed to remote locations.

Computer - Input Devices

У нее резко запершило в горле, и в поисках выхода она бросилась к двери. Переступив порог, она вовремя успела ухватиться за дверную раму и лишь благодаря этому удержалась на ногах: лестница исчезла, превратившись в искореженный раскаленный металл. Сьюзан в ужасе оглядела шифровалку, превратившуюся в море огня. Расплавленные остатки миллионов кремниевых чипов извергались из ТРАНСТЕКСТА подобно вулканической лаве, густой едкий дым поднимался кверху. Она узнала этот запах, запах плавящегося кремния, запах смертельного яда.

 У меня только песеты. - Какая разница. Давай сотню песет. Обменные операции явно не относились к числу сильных сторон Двухцветного: сто песет составляли всего восемьдесят семь центов. - Договорились, - сказал Беккер и поставил бутылку на стол.

Медленно, словно после укола транквилизатора, он поднял голову и начал внимательно рассматривать пассажиров. Все до единого - панки. И все внимательно смотрели на. У всех сегодня красно-бело-синие прически. Беккер потянулся и дернул шнурок вызова водителя. Пора было отсюда вылезать. Дернул .

Стратмор был блестящим специалистом, возможно, лучшим в агентстве. И в то же время после провала с Попрыгунчиком Стратмор испытывал колоссальный стресс. Это беспокоило Фонтейна: к коммандеру сходится множество нитей в агентстве, а директору нужно оберегать свое ведомство. Фонтейну нужен был кто-то способный наблюдать за Стратмором, следить, чтобы он не потерял почву под ногами и оставался абсолютно надежным, но это было не так-то. Стратмор - человек гордый и властный, наблюдение за ним следует организовать так, чтобы никоим образом не подорвать его авторитета.

Войдя, Дэвид увидел мигающую лампочку автоответчика. Слушая сообщение, он выпил почти целый пакет апельсинового сока. Послание ничем не отличалось от многих других, которые он получал: правительственное учреждение просит его поработать переводчиком в течение нескольких часов сегодня утром. Странным показалось только одно: об этой организации Беккер никогда прежде не слышал. Беккер позвонил одному из своих коллег: - Тебе что-нибудь известно об Агентстве национальной безопасности.

 Да, - в сердцах бросил Джабба.  - Шифр-убийца. Но единственный человек, которому известен ключ, мертв.
