| | Generation of computers............... | | The term 'computer generation' is used in relation to the hardware of the computers.Each phase computer development is chractrerised by the type of switching circuits used in them.There are five generations of computers namely,first,second,third,fourth and fifth.Computers which are used vacuum tubes are considered as first generation computers.They were very large in size and their programming was very difficult.The operating speed of first generation computers was very slow.These computer's consuption of power was high.ENIC,EDVAC,EDSAC,AND UNIVAC-I were some computers belonging of the first generation.Second generation computers used transistor,instead of vaccum tubes.these were highly reliable and cheaper than vaccum tubes Development of magnetic cores for storage was done in this period.Also second generation computers used high level languages,such as COBOL,FORTRAN etc.Operating systems also developed in this period.IBM_1401 and UNIVAC_1108 are examples of second generation computers.The third generation computers used 'Integrated Circuits' known as chips.These computers were highly reliable,cheaper and faster than second generation computers.Third generation computers used... | |
| | 2 people overboard on cruise!! | | GALVESTON, Texas - Princess Cruises is investigating how two passengers tumbled off a cruise ship cabin balcony and into the Gulf of Mexico, trigging a four-hour rescue effort. ADVERTISEMENTThe 22-year-old man and 20-year-old woman fell 50 to 60 feet early Sunday from the woman's cabin. Julie Benson, spokeswoman for Princess Cruises, said it appeared to have been an accident.The ship, the Grand Princess, was about 150 miles off the coast of Galveston when friends notified the crew around 1:30 a.m. that the two had fallen, Benson said.The captain turned the ship around, and the crew used high-powered spotlights to scan the water and launched rescue boats to find them. One passenger was pulled into a rescue boat around 5:30 a.m., and the other was found about 30 minutes later, according to a statement by the cruise line. A Coast Guard helicopter crew, called in to help, spotted the male passenger.The man and woman, whom the cruise line declined to name, were examined by the ship's medical staff. They sustained minor injuries, Benson said."Just falling 50 feet, can you do some serious damage and basically knock the wind out of you," said Coast Guard swimmer... | |
| | Vision!!! | | (Some friends have sent mails to me, requesting me to start some discussions on ‘scientific’ topics, which any body can understand & respond, but at the same time, one says: “IT IS NOT YOUR CLASS, WE ARE NOT HERE TO STUDY”. Any way, let me continue my efforts in sharing of knowledge. DR.B.SARAF Ph.D.)
Normal human eye can see ‘clearly’ objects lying from about 25cm to infinity, and all colors. Any deviation from these is called ‘defects of vision’. Our eye is a spherical box, having a variable power ‘convex’ lens at the front and a screen called ‘retina’ on the back. This can focus the image of an object in front of it from about 25cm to a very large distance, on the ‘retina’. If due to any reason,(eye lens becomes thick or eyeball becomes longer) the image gets focused, not on the retina, but a little earlier, then one ‘cannot’ see distinctly, the ‘far’ objects but he may not have problem in seeing ‘near’ objects. This defect is called ‘near vision’. Similarly, if the image is focused, a little beyond the retina, (eye lens becomes thin or eye ball becomes smaller) then he can see distinctly, the ‘near’ objects, while, he may have problem in seeing ‘far’ objects, this is called... | |
