Who invented the typewriter and its keyboard?

There were many different attempts to produce a mechanical writing machine, but the first one to be commercially successful was invented by Christopher Latham Sholes (1819-1890).

He was an American engineer who, together with SW Soule and G Glidden, invented the first typewriter that was later commercially manufactured by Remington, then a sewing machine company.

Their first machine was made in 1866, but the keys jammed easily. To solve this problem they followed the suggestion of a business colleague, James Densmore, who suggested separating the more common letters so that people would have to type more slowly. This was how, in 1868, our QWERTY keyboard originated.

Advantages of computers in entertainment?

The proportion of advantages to disadvantages, we can say it as 1:2.

The computer has also added a myriad of different ways of producing entertainment with motion capture, CGI , computer generated video and sound and animation.

FACEBOOK and other social media could be classed as entertainment. The computer has decimate the music CD business in favor of downloads, they same is happening to cable tv and dvd sales.

What is a host key in computers?

A host key is used by a server to prove its identity to a client and by a client to verify a "known" host. Host keys are described as persistent (they are changed infrequently) and are asymmetric-much like the public/private key pairs discussed above in the Public key section. If a machine is running only one SSH server, a single host key serves to identify both the machine and the server. If a machine is running multiple SSH servers, it may either have multiple host keys or use a single key for multiple servers.

The Host key is a password set by you and acts as the computer's unique access code. It is stored only on your machine and not on the RemotePC servers.

SSH automatically verifies that the host is authentic by comparing the host key in a local database against what the host sends when you connect.

There are two places where the host key is kept. There is a master host key database and a personal host key database. The master host key database is created by ECN with all of the ECN hosts already populated and is satisfactory for most situations. The personal database stores additional host keys when you communicate with a host not supported or outside of the ECN network.

How many musical keys are there?

In the Western tradition of music, there are basically twelve keys, corresponding to the twelve notes of the chromatic scale on a keyboard instrument (ie C, C#, D, D#...etc all the way up to C again). But as these can be either major or minor, we end up with a total of 12 major + 12 minor = 24 possible keys.

Why are the keys on a QWERTY keyboard not arranged in alphabetical order?

The keys on a QWERTY keyboard are not arranged alphabetically because the creator of typewriter layouts designed it where the most used keys were on the home row or within easy reach of the fingers. The least used letters, like Q, X, and Z, are put at the corners of the keyboard, where the fingers take the most effort to reach. Thus, the Qwerty keyboard was arranged for easier typing.

The QWERTY arrangement began with mechanical typewriters.

Every key was linked by rods and levers to an arm with a letter at the end of it. Pushing the key would cause the arm to tilt forward and make an imprint on the paper. If adjacent keys were pushed in rapid sequence, you would activate two adjacent arms, and run a high risk of getting stuck together as one went up and the other went down.

What the QWERTY keyboard did was to put rarely used letters in between the more commonly used letters and thereby reducing risk of the typing arms jamming.

When electrical typewriters and computers came along the habit was so deeply ingrained that we stuck with it, despite the fact that the original reason no longer existed, and that a keyboard with the most commonly used letters placed centrally would be faster, easier and more ergonomic to type with.


In 1875, the inventor of the first keyboard, Christopher Latham Sholes had to come up with a design to stop the keys from getting stuck in his typing machines. With the help of a study of letter-pair frequency provided by educator Amos Densmore, the brother of Sholes' chief financial backer James Densmore, they found a design to hinder this issue. That study provided them with the information needed to come up with the QWERTY setup that is used today. This design was implemented to prevent adjacent key rods from colliding and getting stuck.


When the keyboard on a typewriter was first developed, the keys were arranged alphabetically but the mechanisms (striking arms) for the keys tended to become entangled. By spreading out the commonly used keys, this problem was eliminated.

In any event, a purely alphabetic arrangement could use the same hand too many times in a row, preventing you from setting up one hand while the other is typing. It's much faster to type two letters on different hands than two letters on the same hand.
