Types of Computer Keyboards

Keyboard is very important accessory for our computer. It is used in navigation,execution of process,programming and several other purposes. After all, the keyboard is what you use to input your data, whether it is while you're surfing the net or writing an essay. I can't finish this article without a keyboard. You may say that you can type on the screen and finish the blog, yes, that's sure,but to me, I don't like typing long articles in that way. 

Let us start with types of computer keyboard. Everyone uses keyboard every day, but some of you may do't know how many types are there for computers. By knowing types of computer keyboard, you will find it's not hard to find the satisfactory one anymore.

Laptop Keyboards
The laptop computer keyboard is also called standard keyboard. Standard keyboards include Escape (Esc), Print Screen, Scroll-Lock, Pause-Break, Arrow and other functional keys. Functional keys allow you to tab, type in all caps, insert, delete and perform countless other functions. There's a new standard keyboards, it come with internet short cut keys, which allow you to check emails with a click of a button,store your fav websites and power on and off the internet. What's more, it is also ready for use with a USB port.

Ergonomic Keyboards
Ergonomic keyboards are specially designed computer keyboards with an aim to reduce stress on your wrists and forearms while typing. They have been around for quite some time now, and its been proven that the special contour designs of these keyboards are definitely worth the trouble. Ergonomics isn't a one-size-fits-all science, and there are some keyboards out there that claim to be ergonomic but are not such thing. If you can, test out a friend's ergonomic keyboard before you buy it. While there will probably be an initial learning curve, you should be able to tell pretty quickly if its something that's comfortable for you.


Gaming keyboards
As the name suggests, gaming keyboards are designed specifically for gamer. They include features meant to enhance gaming experience, as well as provide convenient usage for gamer. Those features like volume control, key lighting, programmable keys, interchangeable keys, touch screen to customize the keyboard, in-built joysticks,fancy lighting and so on. Gaming keyboards comes in all shapes and sizes,ranging from round keyboard to v-shaped ones, but this is mainly done as a marketing gimmick to attract gamer. There's some keyboards are just designed for specific types of games. 


Wireless Keyboards
Just as what the name shows, the keyboard don't need to be connected to the computer via a wire. The biggest advantage is that you are free from all the cables and it's really convenient. Wireless keyboards use three basic types of connections, Bluetooth, Infrared, and Radio Frequency to connect to the computer. All the three types of wireless keyboards need external power to function. The power comes from either 2 or 3 'AA' or 'AAA' batteries. A little of wireless keyboard may have an included battery,which can be charged with the help of a USB cable. Any they have one more thing in common, that is all of those types need a transceiver,which connects to a port on the computer and maintains contact between the computer and the keyboard. With so many types available in the market, choosing the right one can be difficult. Knowing the three kinds of keyboard can help you work comfortably and efficiently while keeping your office as cable-free as possible. Among the three kinds, the best one and most popular one is bluetooth keyboards. The technology is only effective over a short range, but it allows for reasonably high data transfer speeds and does not need a direct line-of-sight for connection.
Depending on your needs, one type of keyboard may be more valuable than another. The choices are plenty. as far as I am concerted, I don't think a cheap keyboard is suitable for you, since you use it every day,a relatively cheaper with excellent quality will save you money in the long run. Search Poweradd on Amazon you will find what you are looking for.
