Of the number pad , also known as a numeral, tenor or num block, denotes a particular key area of ​​computer keyboards. The remote part is located on the right side of the keypad. The local elements are used to enter numbers, calculations or special characters. However, not all computers have one number pad , Especially smaller notebooks do without the practical surface, which consists mostly of 18 keys. Practical devices that replace the input surface help here. We introduce the external number blocks for the computer.

Use of the keypad

When layout of a German keyboardcan be found on the right side of the numeric or number pad , This area includes the numbers 0 to 9. There are also numbers for addition, subtraction and multiplication. A division mark and an enter key complete the area. Some keys are double assigned. So can the number pad be disabled via the Num Lock button, which makes use of the keys to control the cursor. Incidentally, a similar arrangement of the keys is found on classical calculating machines.

Many keyboards that are small in size do not have their own number pad , Such input help, which is now integrated into netbooks and some laptops, missing these buttons. Instead, keys are temporarily converted to the numeric keypad. This results in the three or even quadruple occupancy, which makes it much more difficult to perform quick inputs. This shortcoming of laptops or netbooks consumers can encounter by using an additional number pad. The small devices, which often consist of 18 or 19 buttons, can be connected to many computers.

Species overview

Number blocks are created by specialists from Hama, Belkin or Perixx. They are connected either via a USB connection or via radio interface with the respective computer. Wired versions are connected to a computer via USB cable. One example is the Perixx PERIPAD 302H number pad, which is equipped with an eight-centimeter long cable used for connection. Like other number blocks from other manufacturers, this keyboard has an integrated backlight, which makes it easier to enter even in lower light conditions.

With a backlight that can contribute to the handsome appearance of the devices, other variants are equipped, but not via USB, but via Bluetooth connection to laptops, netbooks or other devices are connected. For example, consumers can now use the iClever IC-KP03 number pad, which transmits the inputs to computers via wireless signal. If no entry is made within 30 minutes, the device will enter a stand-by mode. From time to time, integrated rechargeable batteries need to recharge with a mini-USB cable. Other designs are going through batteriesoperated, replace the user after some time.

Functions of number blocks

Some models like the Belkin YourType Bluetooth Wireless Keypad are created for specific computers. They not only visually remind of Apple products, but work well with the iMac, a Mac Pro or the MacBook. Other products are mainly connected to Windows computers. Often the devices can be used directly after the connection, because the respective operating system automatically installs the drivers. Then even some additional USB ports are available for some versions. Finally, some models have additional inputs, so the accessibility features are more versatile than USB hubOffer.

Other variants delight with practical additional functions. So the Ultron UN-1 keypad, which is connected to the computer by a stable 2.4Ghz radio link, is not just a keypad. Finally, even a calculator has been integrated into this number pad, while a solar panel provides the device with solar energy. As a calculator, other versions such as the Satechi Smart keyboard can be used. Then this number pad can also be used without the computer being used as a computer. It is in the consumer’s decision to make this feature worth a higher price.
