There was a time when a single computer occupied the space of a room but now the technology has reached its new heights to the extent that now one doesn’t need the whole of a computer to be carried, not even the laptops. Previously when we had cathode ray tube based desktops, nobody could imagine that laptop would emerge. Then with time the size reduced to tablets and smartphones where you are free to carry and retrieve whatever information you want at any place in the world.
In general, a computer needs at least a monitor, a keyboard and a mouse along with the CPU, RAM, cache and a hard disk to function. These are the physical devices that need space. With time laptops emerged that are light-weighted but that is not the end. Recently devices like virtual projection keyboards are made available in the market. What are they? But before we proceed for that let’s now understand the concept “virtual keyboard”. Around 2 to 3 years back when I was logging in into my bank account to make online payment I saw the option of virtual keyboard. That time I didn’t understand what that was. When a user opts for virtual keyboard he or she doesn’t have to use the physical input device to enter the password. Instead of that, they are given the soft keyboard right on the screen that resembles the image of the literal device. This is done in order to prevent the person from keystroke logging. Through keystroke logging the actions of the user are monitored without them being aware of, as and when they type the keys. This technique is done for hacking the password. Virtual keyboards are hence popular due to the same reason and are indeed trustworthy.
