There are also keyboards that use an 8 pin connector. Just like a mouse. 8 pin connectors are mostly used on old computers. The best types of keyboards are the optical ones. An optical keyboard is a keyboard that does not use any leads or connectors to a computer. This type of keyboard allows the user to move around freely. The keyboard cannot be taken away a long distance. This is because the keyboard uses a sensor, and when the keyboard cannot sense any signal it won’t work
Nearly every keyboard is the same, but sometimes there are some types of keyboards that have different functions on them. Each of the different buttons on the keyboard has a different link to the computer. The keyboard is one of the most important hardware devise that can be used on the computer. Most keyboards have the function of a mouse.
Another common input device is the mouse. Almost any time we use a computer we use one or both of these to get text data or instructions into the system. To get large amounts of information into the computer we would probably use a CD compact disc, a floppy diskette, a modem connected to a phone line, or a network card connected to a network. These are all types of hardware devices.
Now most computers have USB ports, but this doesn’t mean that it makes it easier for the user to use. The only thing that it makes better is the USB part of the lead. This is because sometimes the pins in the other mouse can sometimes bend or even break. People are sometimes impatience and try to insert the lead. The next thing that you know is that one of the leads is bent or broken. It can make life harder for the technician to try and fix it.
There are different types of mice. There are all sorts of mice such as USB, or even 8 pin mice. The 8 pin mice mostly work on older computers. And the USB connector is mainly used on the newer computers nowadays. The disadvantage about an 8 pin mouse is that sometimes the pins can snap or even bend. These types of mice do work but are now an old model.
A USB mouse would be more efficient. This is because computers nowadays use more USB ports. They don’t take up much space on the computers and there is nothing to break, as for the 8 pin mice, one or more of the pins can snap.
Another thing about a mouse is that they use sensors as well. Sensors nowadays are more efficient. There are two types of mouse, one is called optical and the other is called a ball mouse. Sometimes people can take out the ball from the mouse and that would be pretty useless. The optical mouse is more use full and it is much better. This type of mouse is light and there is no ball needed. This mouse uses a sensor that is connected into the computer, using a USB connection. The word USB stands for universal serial bus.
A monitor is an output devise. A monitor is an output devise because the text and pictures are transmitted from the computer to the monitor. Another hardware unit is the monitor. The monitor is one of the most important hardware units used. Without the monitor you cannot use the computer at all. With the monitor you can see what is going on. The monitor is a display device. The monitor displays the pictures and the text, from the actual computer.
There are mainly two types of monitors. As you can see below there is a flat panel monitor, and a standard CRT monitor.
This is a flat panel monitor. This is the type of monitor used more nowadays.
This is the standard CRT monitor. This model is kind of old but is rarely used nowadays.
Different types of monitors give different picture, text and graphic quality. Basically a monitor is a display devise that takes signals from a computer and displays the picture on a CTR screen.
This connector is the most common connection device used to connect a monitor and the computer.
USB memory sticks are a convenient way to transport large amounts of data around on a device you can fit in a pocket. USB memory sticks are:
- Faster than floppy disks.
- Smaller and are able to fit in a pocket.
- They store much more data than a floppy disk.
- They are more convenient than a CD-R or CD-RW for many purposes.
- They require a USB socket on the computer to plug it in.
So these are all the positive things about a USB memory stick. There are other type of storage devise ike a memory stick, but something more bigger and better is a hard drive. Hard drives are mechanical devices that are used by computers to hold information A hard drive is always used in a computer. And on this hard drive you can save a lot of data onto this hardware.
