At the Airport

Laura is at the airport. She waits for her flight.
Her flight is to Berlin, and it is 4 hours away. Laura
walks around the airport and looks at the shops. She
has a nice time.
After an hour she wants to visit the bathroom.
She searches for it, but she doesn’t find it. “Where is
the bathroom?” she asks herself. She looks and looks
but she can’t find it. She starts asking people
where it is.
Laura: “Excuse me sir, could you please tell
mewhere is the bathroom?”
“The restroom is over there,” the lady
answers andwalks away.
Laura is confused. “What’s their problem?
I need to use the bathroom and they send me to rest?!
I don’t need a restroom, I need the bathroom!”
After a while Laura gives up. She feels tired of
all this walking and asking. She decides that maybe
they are all right and she does need to rest. She walks
to the restroom. Now she is surprised. She realizes
the restroom is actually the name for a public
bathroom!

English for Adults & Seniors!

Learning a language isn’t only for the young! It’s for everyone and if you are an older learner,maybe 40+ to 70+ then joining an English Language Course in an environment with people in similar age groups is a greatway to do it.

When you join a course at one of the International Schools you will find that approximately more than 20% of our students are aged 30 to 44 and a further 32% are aged 45 to 75 - sometimes older. You aremore than likely to find yourself in a class with people of a similar age;

Some mature students choose Business English courses for their working needs but many more join standard General English courses or the Intensive English Mini-Group courses. Courses like these help you to combine your language course with a holiday and you can make your own afternoon programme or join social programmes which are designed to have a variety of different activities suitable for all the age groups at the school. The programme changes every week and you can see samples of all the different activities on the social programme pages or on Facebook pages.

Mature learners will feel safe joining one of the International Schools. You will find others of a similar age in your class at all times of year

The International School ( I S ) accommodation is also suitable for older clients - you can choose froma homestay with a private bathroom, an apartment, but most convenient of all is Club IS Hotel which is opposite the school. Club IS is for mature individuals who are studying at the school. Classes are always organised according to level and according to age groups.

Man: “Youmean the restroom, right?”
Laura: “No, Imean the bathroom.”

Laura doesn’t understand. She asks a lady: “Excusememadam, could you please tellmewhere is the bathroom?”

“The restroom is over there,” the lady answers andwalks away.

Computers are used to control a wide range of systems from simple domestic machines, through games controllers, to entire manufacturing plants. These computers interact directly with hardware devices. Their software must react to events generated by the hardware and, often, issue control signals in response to these events. These signals result in an action, such as the initiation of a phone call, the movement of a character on the screen, the opening of a valve, or the display of the system status. The software in these systems is embedded in system hardware, often in read-only memory, and usually responds, in real time, to events from the system’s environment. By real time, I mean that the software system has a deadline for responding to external events. If this deadline is missed, then the overall hardware-software system will not operate correctly.

Embedded software is very important economically because almost every electrical device now includes software. There are therefore many more embedded software systems than other types of software system. If you look around your house you may have three or four personal computers. But you probably have 20 or 30 embedded systems, such as systems in phones, cookers, microwaves etc

Responsiveness in real time is the critical difference between embedded systems and other software systems, such as information systems, web-based systems, or personal software systems, whose main purpose is data processing. For non-real- time systems, the correctness of a system can be defined by specifying how system inputs map to corresponding outputs that should be produced by the system. In response to an input, a corresponding output should be generated by the system and, often, some data should be stored. For example, if you choose a create command in a patient information system, then the correct system response is to create a new patient record in a database, and to confirm that this has been done. Within reasonable limits, it does not matter how long this takes.

However, in a real-time system, the correctness depends both on the response to an input and the time taken to generate that response. If the system takes too long to respond, then the required response may be ineffective. For example, if embedded software controlling a car braking system is too slow, then an accident may occur because it is impossible to stop the car in time.
