Why do modern computers have PS2 ports?

PS/2 is good for N-key rollover, low latency, and the fact that it practically always works. If I have an issue with a USB keyboard that forces me to re-plug it in with each boot, I may not be able to reach the bios due to such an issue.

What is the old connector we used for mouse and keyboard?

PS/2 port
The PS/2 port is a 6-pin mini-DIN connector used for connecting keyboards and mice to a PC compatible computer system. Its name comes from the IBM Personal System/2 series of personal computers, with which it was introduced in 1987.

Which is better PS2 or USB keyboard?

No. In fact, PS/2 ports are worse than USB or serial, because they don’t support plugging a device in without a reboot, and on many systems you have to get them the right way round or they don’t work. In fact, PS/2 ports are only provided for compatibility with old keyboards and mice these days.

What is the difference between a USB mouse and a PS2 mouse?

This motherboard has two PS/2 ports and four rear-side USB ports. The only difference between a USB and PS/2 mouse is how the device connects to a computer. While USB has superseded PS/2 and is the modern peripheral device connection standard, it’s hardly new, and the PS/2 standard is far from dead.

Does it matter which USB port you use for mouse and keyboard?

There are two types of USB ports which look physically identical; USB 1.1 and USB 2.0. Your computer will advise you if a device would benefit from using a USB 2.0 port if you plug it into a USB 1.1 port. You will not harm your keyboard or mouse by plugging it into a USB 2.0 port.

Which connector is used to attach a mouse to a modern PC system?

Why do keyboards have 2 USB plugs?

What are the advantages of using an external keyboard over USB?

But it also has many other advantages over USB, such as: It does not require drivers of any kind . When you connect a USB keyboard to the PC, for example, a driver must tell the computer what you are connecting to that port.

What do the purple and green ports mean on a motherboard?

In many motherboards we can still see these ports, which are also indicated with color code and even with icons: purple is for the keyboard, and green is for the mouse. In fact, in many cases we can see PS / 2 combo ports that are compatible with both peripherals (and that a splitter was necessary to connect the two to the same port).
