The typewriter was invented in 1878 and the keyboards are the descendants of the typewriter. The layout of the typewriter keyboard and the computer keyboard is almost the same. The PC keyboard has additional keys, which are not found in the typewriter.  The keyboard should be carefully selected to avoid wrist and finger pains.

Mechanical Keyboard Review:

In this type of keyboard, each key has a mechanical switch that records the keystroke.   In other words, it can be said that the physical switch under each key is triggered and the key returns to its position for another click. A mechanical keyboard is more durable than the PC keyboards as repetitive key pressing in the mechanical one is not problematic due to the presence of metallic contact points.

Mechanical Keyboard Key Benefits:

• The mechanical keyboards can be pressed 50 million times in total before being deteriorated
• The mechanical keyboard produces more sound in comparison to the PC keyboard due to the presence of metal under the keys.
• Playing games with a mechanical keyboard is easy as multiple keys can be pressed simultaneously. The mechanical keyboard is easy to clean due to the presence of metal.

Ordinary PC Keyboard Review:

The PC keyboard has rubber dome, which allows it to record keystrokes and then the keys are returned to their original position for pressing them again. This type of keyboard is cheap in comparison to a mechanical keyboard.

Ordinary PC Keyboard Benefits:

• PC keyboard can be pressed only 10 million times before being deteriorated and this is due to the collapsed rubber domes and sticky keys.
• PC keyboard produces less sound due to the presence of rubber underneath.
• PC keyboard is not good for playing games as multiple keys cannot be pressed simultaneously.
• PC keyboard is difficult to clean due to the presence of rubber.
