===What is ICT===

Have you ever seen anyone in your school or community or home use a phone?  Have you ever withdrawn money from an ATM or seen someone get money from an ATM? You may have seen or helped someone book a gas cylinder refill through a phone. You may perhaps have booked a train ticket or Tirumala darshan online. You may have seen a movie on your computer or chatted with a friend or recorded a video with your phone.  Have you ever wondered how these things are done?  There is one thing common that is common across all these things - the use of Information Communication Technologies, ICT.

Have you ever seen anyone in your school or community or home use a phone?  Have you ever withdrawn money from an ATM (Automated Teller Machines, also known as 'Any time money'), or seen someone get money from an ATM? You may have seen or helped someone book a gas cylinder refill through a phone. You may perhaps have booked a train ticket or booked Tirumala darshan on-line. You may have seen a movie on your computer or chatted with a friend or recorded a video with your phone.  Have you ever wondered how these things are done?  There is one thing common that is common across all these things - the use of Information Communication Technologies, ICT.

As students, you have been introduced to some or many of these terms in your school, in your family or in your neighbourhood.  The cell phone tower, your nearest ATM, your mother's mobile phone, games, whatsapp chats, email, the selfie, internet, videos and songs on your computer - all these are examples of a new kind of technology.  These technologies are called [http://www.dictionary.com/browse/digital-technology digital technologies] and they are changing the way we talk to each other, work with each other, and the way we do things.  The computer is becoming like a television, the phone is becoming like a computer, you can use the computer to make voice calls, you can record a video with your phone, you can read your newspaper on the phone, and you can even paint with your computer!

The technologies that make all these possible are collectively called ICT.  ICT refers  to those set of technologies that help us create information, access information, analyze information and communicate with each other. Human beings have always accessed information and communicated, but what makes these present technologies special is their digital nature.  You can read more about how ICT developed in the chapter on [[ICT_student_textbook/Science_Technology_and_Society|Science, Technology and Society]].

Let us say you are withdrawing money from a nearby ATM.  Can you make a list of all the information requirements for doing that activity?  That is correct, you need your account number, your PIN and you need to enter the amount of money.  When you put your card in the machine, it collects information about your bank account, the bank and the balance amount.  The ATM machine verfies your PIN with the bank and allows you to withdraw the money.
