1.
Read the following passage carefully. (8)
Medicine, however, is not the only application for Expert Systems. The oil-exploration company Schlumberger uses these computers for predi cting drilling conditions, and Stanford University, USA, a leader in Expert System s, has programs such as DENDRAL to build models of molecules from chemical data. 1. By this method, a computer merely performs seque ntially, a series of arithmetic operations. All its advantages are due to the fact that it works extremely quickly, but its achievements are governed entirely by its program. A small programming error, no matter how trivial, results in the program crashing -failing to run because the machine cannot deduce what the programmer meant to write. 2. One exciting aspect of these parallel computers is that they can possess artificial intelligence. Such machines will have the ability t o make decisions, to use deductive logic, to criticise constructively and to advise. I n Japan, for example, the newly formed Institute for New Generation Computer Technology ha s been developing a machine to mimic human thought patterns, respond to spoken com mands, translate languages and make intelligent robots possible. One particular ty pe of AI system already finding widespread use is the Expert System. This is a comp uter that contains the facts that a human expert would use to solve problems. 3. Thirdly, the new generation of computers will pr ocess data in an entirely different way. Rather than operating sequentially, the machines wi ll contain many (perhaps a million) of CPUs each in two- way electronic communication w ith others. This parallel method of operation enables many different tasks to be handle d simultaneously by processes thought to be similar to those in a human brain. 4. At the University of Pittsburgh, USA, there is a computer that can diagnose illnesses by a program called INTERNIST. The machine contains info rmation on over 500 different diseases, each linked to an average of 60 probable symptoms. The doctor tells the computer the symptoms of the patient and the machin e lists a set of likely diseases, then narrows its selection by asking the patient a set of questions about the ailment. Within a decade, computer aids diagnosis may become commonplace in the consulting room.
Answer the following questions briefly:
(i) How are all achievements of computers controlled?
(ii) How can a machine be upset?
(iii) What will the new generation of computer enable?
(iv) Who is called Internist?
(v) How will the new generation of computers process data?
(vi) What is the exciting aspect of these parallel computers?
(vii) Which computer is called the symptoms of the patient by the doctors?
(viii) What do you mean by ‘trivial’ here?
2. Read the passage carefully. (12)
You hope to do several things every day. At the end of each day, most of them are not done. You may be using a ‘to-do-list’ but discover in a s hort while that it is not helping you much. Tasks keep adding to it. In a few weeks, it starts looking like a list of things you will never do and you feel stressed about it. Making a to-do-list is not enough. It is useful onl y when you understand the key aspects of it and work on it further. To begin with, recognise that a to-do-list is only a pool of tasks. It is just a raw collection that gives you no idea of how you will get to it. T o make it useful you have to define the ‘when’. Entering details about when you will do the different tasks, gives the to-do-list a meaning. When you begin creating a schedule, your f ocus shifts to how long you have to work on each task to complete it. This way you are forced to be realistic about your goals. You cannot do all the tasks on the list on the same day. So, you should learn to prioritise. Rank the tasks using numbers or group them using le tters of the alphabet, according to the order of importance. Now start working according to the schedule where your schedule went wrong by paying close attention to how you are spending the day. Some of the possible reasons are: you waste time, m ade mistake in assessing how much time a task would take or deal with ‘urgent’ tasks frequently. If the reason is wasting time, learn to concentrate on your work. If you made a mi stake in time assessment, prepare a more realistic schedule. Another way to prioritise tasks is based on the cre ative energy they require. Separate the tasks into creative and boring ones. This approach helps you to stay productive even during cheerless parts of the day. Making schedule for items in your to-do-list does n ot promise that all of them are accomplished. But you can at least be strategic abo ut what is left behind and feel happy that you achieved what you accommodated in the finite sp ace. This way you can begin the next day on a confident note rather than feeling helples s and frustrated about failing
(i) What makes a ‘to-do-list’ useful?
(ii) Why is the ‘to-do-list’ described as a raw collection?
(iii) What is ‘prioritising’?
(iv) How do you become realistic about your goals?
