इन्जिनियरिङ (अभियांत्रिकीशास्त्र) भनेको मानविय समस्या समाधानका लागि प्रबधिको प्रयोग गरिने विज्ञान हो। बास्तवमा, इन्जिनियरिङ एक ब्यबसायिक कार्य हो जसमा सोच, फैसला गर्ने क्षमता , र बौदिक ज्ञान प्रयोग हुन्छ, जसमा बिज्ञान, प्रबिधि, गणित, र प्रयोगात्मक अनुभव प्रयोग गरि परिक्लपना, उत्पादन, र उपयोगि वस्तुको प्रयोग अथवा क्रम हो जसले मानबताको आवस्यकता र रहर पुरा गर्ने बिषय हो. इन्जिनियरिङको ब्यबसायिक प्राविधिकलाई इन्जिनियर भनिन्छ।

'"कम्प्युटर"' अंग्रेजी: Computer जसलाई नेपालीमा 'सुशाङख्य' पनि भनिन्छ एउटा प्रोग्रामेबल यन्त्र हो। यस यन्त्रको बनावट लगातार रस्वचालित भई गणितिय अथवा तार्क्रिक क्रमांकहरूको कार्य पुरा गर्ने हुन्छ। कुनै पनि क्रमांकको कार्यलाई चाहे जति परिवर्तन गरेर कम्प्युटरलाई एक भन्दा धेरै समस्याहरू समाधान गर्न प्रयोग गर्न सकिन्छ।

सामान्यत: कम्प्युटरमा हुने एक प्रकारको मेमोरिमा तथ्याङ्क भन्डारण गरिन्छ, कुनै एक वस्तुले गणितिय तथा तार्क्रिक कार्य गर्दछ भने अर्को क्रमांक तथा नियन्त्रण वस्तुले कार्यहरूको श्रेणि जानकारिको भन्डारणको आधारमा परिवर्तन गर्दछ। यसमा हुने पेरिफेरल साधनहरूले जानकारिलाई बाहिरि बाट भित्र्याउनुका साथै परिणामलाई बाहिर श्रोता समक्ष पुर्याउँछन्।

कम्प्युटरको प्रोसेसिङ विभागले जानकारिहरूको पंक्ति सम्पादन गरेर तथ्याङ्क पठ्ने, निर्वाहित गर्ने तथा भन्डारण गर्ने गर्दछ। निर्णायकजानकारिले क्रमांकिक जानकारिलाई यन्त्रको अथवा वातावरणको हालको अवस्थाको क्रित्यका आधारमा परिवर्तन गर्छ।

पहिलो विध्युतिय कम्प्युटरहरू २०औं शताब्दिको मध्य(सन् १९४०-१९४५)मा विकसित भएका हुन्। मौलिक रूपमा, तिनिहरू ठुला कोठाको जत्रो नाप भएका र विध्युतिय खपत हजारौं आधुनिक कम्प्युटरहरूले जति गर्ने खालका थिए।

आधुनिक कम्प्युटरहरू ईन्टिग्रेटेड सर्किट्स प्रविधिका आधारमा बन्ने भएकाले यिनिहरू पहिलेका यन्त्रभन्दा लाखौं-करोणौं गुना बडि क्षमतावान् र नाप मात्र केही अंशका हुन्छन्। सामान्य कम्प्युटरहरू प्रशस्तै सानो हुने हुँदा यिनिहरू मोबाईल साधनमा सजिलै अटाउँछन्, मोबाईल कम्प्युटरलाई विध्युतिय पावर साना ब्याट्रिबाट सजिलै उपलब्ध गराउन सकिन्छ। पर्सनल् कम्प्युटरहरू आफ्नो अनेकौँ रूपमा ईन्फर्मेसन् युगका मर्ति हुनुका साथै धेरै मानिसले सोच्ने गरेका 'कम्प्युटर्स्' हुन्। अन्तत: ईम्बेडेड कम्प्युटरहरू धेरै खाले उपकरणहरू एम पि थ्रि प्लयेर्स् देखि आधुनिक युध्द विमान र खेलौना देखि उध्योग यन्त्रमानव सम्म प्रचुर मात्रामा प्रयोग गरिन्छ।

Attempt all Questions:

1. Read the given passage and answer the questions.

A. They play hard, they often, and they to win. Australian sports teams win more than their fair share of titles, demolishing rivals with seeming ease. How do they do it? A big part of the secret is an extensive and expensive network of sporting academies underpinned by science and medicine. At the Australian Institute of Sport (AIS), hundreds o youngsters and pros live and train under the eyes of coaches. Another body, the Australian Sports Commission (ASC), finances programmers of excellence in a total of 96 sports for thousands of sportsmen and women. Both provide intensive coaching, facilities and nutritional advice.

B. Inside the academies, science takes centre stage. The AIS employs more than 100 sports scientists and doctors, and collaborates with scores of others in universities and research centers. AIS sciences work across a number of sports, applying skills learned on one-such as building muscle strength in golfers – to others, such as swimming and squash. They are backed up by technicians who design instruments to collect data from athletes. They all focus un one aim: winning. 'We can't waste our time looking at ethereal scientific questions that don't help the coach work with an athlete and improve performance, says Peter Fricker, chief of science at AIS.

C. A lot of their work comes down to measurement – everything from the exact angle of a swimmer's dive to the second power output of a cyclist. This data is used to wring improvements out of athletes. The focus is on individuals, tweaking performances to squeeze an extra hundredth of a second here, an extra millimeter there. No gain in too slight to bother with. It's the tiny, gradual improvements that add up to world-beating results. \to demonstrates how the system works, Bruce Mason at AIS shows off the prototype of a 3D analysis tool for studying swimmers. A wire-frame model of a champion swimmer slices through the water, her arms moving in slow motion. Looking side-on, Mason measures the distance between strokes. From above, he analyses how her spine swivels. When fully developed, this system will enable him to build a biomechanical profile for coaches to use to help budding swimmers. Mason's contribution to sport also includes the development of the SWAN (SWimming ANalysis) system now used in Australian national competitions. It collects images from digital cameras

Running at 50 frames a second and breaks down each part of a swimmer's performance into factors that can be analyses individually-stroke length, stroke frequency, average duration of each stroke, velocity, start, lap and finish times, and so on . at the end of each race, SWAN spits out data on each swimmer.

D. "Take a look ", says mason, pulling out a sheet of data . he points out the data on the swimmers in second and third place, which shows that the one who finished third actually swam faster . So why did he finish 35 hundredths of a second down? His turn times were 44 hundredths of a second behind the other guy's, says Mason. If he can improve on his turns, he can do much better." This is the kind of accuracy that AIS scientists' research is bringing to a range of sports. With the Cooperative research centre for Micro Technology in Melbourne, they are developing unobtrusive sensors that will be embedded in an athlete's clothes or running shoes to monitor heart rate, sweating. Heat production or any other factor that might have an impact on an athlete's ability to run. There's more to it than simply measuring performance. Fricker gives the example of athletes who may be down with coughs and colds 11 or 12 times a year. After years of experimentation, AIS and the University of Newcastle in New South Wales developed a test that measures how much of the immune-system protein immunoglobulin A is present in athlete's saliva. If LgA levels suddenly fall below a certain level, training is eased or dropped altogether. Soon, LgA levels start rising again, and the danger passes. Since the tests were introduced, AIS athletes in all sports have been remarkably successful at staying healthy.

E. Using data is a complex business. Well before a championship, sports scientists and coaches start to prepare the athlete by developing a 'competition model', based on what they expect will be the wining times. You design the model to make that time , says mason. 'A start of this much, each free-swimming period has to be this fast, with a certain stroke frequency and stroke length, with turns done in these times.' All the training is then geared towards making the athlete hit those targets, both overall and for each segment of the race . techniques like these have transformed Australia into arguably the world's most successful sporting nation.

F. Of course, there's nothing to stop other countries copying-and many have tried. Some years ago, the AIS unveiled coolant-lined jackets for endurance athletes. At the Atlanta Olympic Games in 1996, these sliced as much as two per cent off cyclist's and rower's times. Now everyone uses them. The same has headed to the altitude tent', developed by AIS to replicate the effect of attitude training at sea level. But Australia's success story is about more than easily copied technological fixes, and up to now no nation has replicated its all-encompassing system.
