Keyboard extension cables and mouse extension cables
If keyboard or mouse cables are too short, you can extend them simply using a PS/2 extension cable. For example, this means that you can place desktop computers safely where nobody will trip over them and they will not be damaged. This is particularly useful in workshops, sales showrooms and school classrooms. These cables also mean you do not have to replace tried and tested devices or buy new ones. It also eliminates the need to upgrade to cordless mice or keyboards.
