The QWERTY keyboard originates from typewriters.
Different key combinations were tried when typewriters were initially released, but often the letters clashed and jammed. The QWERTY design was finalised and proven successful in the late 1800s and has been used since.
It is the line of keys that you place your fingers on when typing. This is a way that most people type fastly.
A hybrid bridge is a device with four branches that are systematically arranged in a way that input signal is equally divided between the adjacent branches. These are also known as hybrid junction or hybrid tee.
It doesn't. Superconductors have no (virtually no) losses, they are purely inductive. This has no bearing on how current flows. Normal conductor will heat up due to resistive losses of the line (I^2 R losses), while a superconductor shouldn't.
Hi, Single mode fiber is used to send the data from transmitter to receiver or repeater. In single mode we can only send single signal at a time and hence it is single mode. The Single mode fiber will have core and cladding arranged in such a way that the core has got one refractive index and the cladding has got another refractive index which will be constant through out the fiber.
A scancode (or scan code) is the data that most computer keyboards send to a computer to report which keys have been pressed. A number, or sequence of numbers, is assigned to each key on the keyboard.
because the inventor of the keyboards last name was qwerty
its called QWERTY pad because the first six letter on the qwerty pad are Q W E R T Y
They were based on the frequency of use and the strength of the fingers. The little fingers don't do much, while the first couple of fingers do most of the work.
This goes back to the first typewriters in the 1800s that were mechanical manual machines. Originally the keys were arranged in alphabetical order. However typing english text on such a keyboard resulted in too many hammer clash jams (adjacent hammers would get stuck against each other and the typist would have to stop and unjam the machine). The fix, after some experimentation, was to jumble the keys into the modern "qwerty" order so that it was very rare for adjacent keys to be typed in sequence.
The average keyboard is arranged in Qwerty. Look at the upper left hand corner, and you'll see that on the top line, Qwerty is spelled. I think that Qwerty is the company's name, or the inventor's name.
because theywere the first le4ters in the type writer
Qwerty keyboard is the standard keyboard designed for typewriters and or cellphones. It contains the letters in the top row of the keys. It was designed in this manner back in 1868 by Christopher Sholes , when he invented the typewriter keys. It was designed this way to prevent sticking of the keys, although it did slow down the speed in which typing could occur.
to keep the hammers from hitting each other and jamming.
The "QWERTY" keyboard (named for the first 6 letters on the top row) was developed to slow down typists on old manual typewriters. With a regular ABCDE.. keyboard setup they would type too fast and cause the keys to jam. With the QWERTY setup they typed slower and prevented key jams. It became the accepted standard and persists even after electric typewriters & computers made the original reason irrelevant.
Well this is an ambiguous answer but is on track. It has been found that the current QWERTY layout of the keyboard is optimised for humans when processing information: The QWERTY design is based on a layout created by Christopher Latham Sholes in 1873 in Milwaukee there are some contemporary alternatives: instead having the sequence "DHIATENSOR" in the home row, these 10 letters being capable of composing 70% of the words in the English language. but to date they have not been widley adopted
When typewriters were first invented, it used to be alphabetical, but because the keys and bars to strike the hammers that hit the paper were close to each other, they would often jam. The person to first invent the jam free keyboard for the keys that would be used most often to be further away from each other and then arranged the rows to have most used letters on the middle row, second most on the top, and least used on the bottom row of the alphabet section. After decades of using this layout, it shifted to computers because it would be more expensive to teach everyone in the world a new layout then to just keep it the way it is. There are key layouts that were made to be more efficient, but they fail due to lack of popularity.
to make it unlikely (or at least less likely) to cause hammer clashes and hammer jam ups when typing english language text rapidly using all 10 fingers on manual mechanical typewriters. this is kind of irrelevant on electronic computer keyboards as there are no hammers to jam and much of what is typed bears no resemblance to the english language.
