THE DIGITAL AGE
We
are now living in what some people call the digital age, meaning that computers
have become an essential part of our lives. Young people who have grown up with
PCs and mobile phones are often called the digital generation. Computers help
students to perform mathematical operations and improve their maths skills.
They are used to access the internet, to do basic research and to
communicate
with other students around the world. Teachers use projectors and interactive
whiteboards to give presentations and teach sciences, history or language
courses. PCs are also used for administrative purposes – schools use word
processors to write letters, and databases to keep records of students and
teachers. A school website allows teachers to publish exercises for students to
complete online.
Students
can also enrol for courses via the website and parents can download official
reports. Mobiles let you make voice calls, send texts, email people and
download logos, ringtones or games. With a built-in camera you can send
pictures and make video calls in face-to-face mode. New smarthphones combine a
telephone with web access, video, a games console, an MP3 player, a personal
digital assistant (PDA) and a GPS navigation system, all in one.
In
banks, computers store information about the money hed by each customer and
enable staff to access large databases and to carry out financial transactions
at high speed. They also control the cashpoints, or ATMs (automatic teller
machines), which dispense money to customers by the use of a PIN-protected
card. People use a Chip and PIN
card
to pay for goods and services. Instead of using a signature to verify payments,
customers are asked to enter a four-digit personal identification number (PIN),
the same number used at cashpoints; this system makes transactions more secure.
With online banking, clients can easily pay bills and transfer money from the
comfort of their homes.
Airline
pilots use computers to help them control the plane. For example, monitors
display data about fuel consumption and weather conditions. In airport control
towers, computers are used to manage radar system and regulate air traffic. On
the ground, airlines are connected to travel agencies by computer. Travel
agents use computers to find out about the availability of flights, prices,
times, stopovers and many other details.
