The first true supercomputer, CRAY-1 (photo, left) made in 1976, ran at a speed of 100 megaflops. (A flop is the number of mathematical operations involving decimal fractions that a computer can make in a second. Mega = 1000.) At present the fastest supercomputer is China’s Tianhe-1 (see photo, below) which can … Read more
The transmission route of an SMS (short message service) is not different from that found in phone calls. Whenever a person sends an SMS through his mobile phone, that data or the contents of the message will be first received by the SMS center of the network service provider that the sender … Read more

A human brain consists of nearly 100 billion cells regarded as neurons. These are super tiny switches that allow people to think and recall things. Computers also contain what seemingly are billions of brain cells called as transistors. They switch signals on and off like neurons and perform at high speeds at … Read more
NASA had been working for a while to come up with the world’s first communication satellite. Since the project was bound to be complex, NASA encountered numerous hurdles along the way until it was finally prepared to try its experiment in 1960. The experiment initiated from Project Echo, which was the first … Read more
Nothing! There’s fat chance of such a mistake taking place in the first place! Narrow necks of fuel tanks of petrol combustion cars will not allow the wider nozzle of diesel dispenser to enter inside the petrol tank, thereby cautioning the absent-minded petrol pump attendant to rectify his mistake. The nozzle of … Read more
Before World War 2, the only way for a pilot to escape an incapacitated aircraft was to bail out! He had no other way than to jump, but that was almost impossible due to the compression forces, the high flow of air past the aircraft and the possibility of fatal injuries. However, … Read more
Intel Core i9, AMD Ryzen series, and RTX 2020 – are just some common parts you’ll see in a custom-built Personal Computer, or what we commonly know as “PC.” But when exactly did this advanced computing technology started that we know today? The actual first personal computers were introduced in 1975, which … Read more
