The more years the development of computers is increasing. This progress can not be separated from the manufacture of various kinds of hardware. Of course this is to increase the ability of the computer. Without hardware the computer cannot perform certain tasks. Software can be run because of hardware. The presence of hardware is very important for the implementation of various activities in the software. Here is an example of hardware :
A. Keyboard
Useful for the process of typing various words in Microsoft Office, performing short operations such as pressing ctrl+windows to close pages, and operating games. Which As we know the shape is flat with dozens of buttons attached to it. In the past, the keyboard used a cable as a connector. Now the cable is attached to the computer.
B. Speaker
Is hardware that serves to increase or decrease the volume of the sound. This is because the computer volume is limited. Especially if used for many people in an event. For example when the percentage. The market is a box-shaped speaker with a concave amplifier at the top. With a dedicated volume dial underneath.
C. Flashdisk
The point is to retrieve and send data between computers. The device is removable, making it a versatile tool for transferring files. But sometimes can not be separated from the virus attack. And this can cause him to lose important data. Fortunately there is an antivirus as a solution. Judging from the physical form of the flash so small. Just a flat metal covered with plastic. And very susceptible to damage when exposed to water.
D. Mouse
Has a function to direct the arrow. In the process of clicking on the icon or drawing via special software such as corel draw. As the name suggests, the mouse looks like a mouse. Where there is usually a trackball underneath that makes the mouse move.
E. Joystick
This is a tool to play multiple games. With the joystick control the game can be more fun. Especially used when we want to play with other people on one computer. Its flexible shape allows it to be moved freely. We know the joystick with the shape of the letter m. Where there are 4 buttons on the right side. And 4 buttons on the left side. To control motion. This device uses a cable as a connector.
F. Modem

Modems usually have a certain capacity. And can be refilled. Where the form of the modem varies depending on the type. Sometimes characterized by the presence of a long metal as a signal receiver.
G. Compact Disk
A piece of hardware whose function is to store a certain amount of data for a long period of time. When inserted into the slot in the machine. The data will be connected to the computer so that it can be read. In the end we can run certain activities. For example, playing video games. Compact disc is round. And the maker makes a hole in the middle so that this tool can rotate in one direction. We have to be careful using it because a scratch can sometimes damage it.
H. Processor
It can be said as the center of all walking activities. Where this is what makes all software can work fully. It used to be big processors and filled with cables. Now the form of the processor is a mini box. And usually in the middle there is an identification mark. Without a computer processor is just an inanimate object.
I. Headphones
With this tool we can listen to the volume without being heard by others. The sound will not sound from the screen but is transmitted through the device. Through the connection between networks. The most common form is the letter n. With two large circles as earplugs. Which is made of soft foam.
In addition to the hardware above, of course, there are many devices that we don't know about. Of course, new hardware will continue to be created as long as there are user needs.
