The PS/2 port was introduced on the IBM PS/2 line in 1982. IBM designed the PS/2 port as a more secure connection for keyboards and mice.
Almost a decade after the PS2’s discontinuation in North America, many motherboards still include PS2 ports.
Most motherboards still have PS2 ports because they are required for the BIOS to communicate with the keyboard and mouse. One of the most apparent reasons is compatibility.
The PS2 port is a legacy port that is not present on most new computers.
What Are PS/2 Ports?
A PS/2 port is a connection interface used for keyboards and mice.
It is a 6-pin mini-DIN connector and is used on IBM PC-compatible computers.
PS/2 ports are found on the back of most desktop computers.
What Does the PS/2 Port Do?
The PS/2 port is a legacy computer port that was used for input devices, like keyboards and mice.
It’s been replaced by USB ports on most modern computers, but you can still find it on some older machines. PS/2 ports are rectangular and have six pins.
The PS/2 port is also known as the “mini-DIN” port.
Why Has The PS/2 Port Not Disappeared From Modern Gaming Machines?
The PS/2 port is still found on modern gaming machines because it is a very versatile interface. This can be used for various purposes, including connecting a keyboard, mouse, or controller.
The PS/2 port is also found on some gaming laptops, allowing an easy way to connect to an external keyboard or mouse.
Most PCs and gaming machines have moved to USB ports for these peripherals.
So Why Do Motherboards Still Have Ps2 Ports?
There are still many reasons why motherboards continue to have PS2 ports. One reason is that some devices still use PS2 connectors, such as keyboards and mice.
some reasons are;
- Used by Enterprises for Security
- Gamers Love the Low Polling Rate and N Key Rollover
- Great With BIOS, PC Hardware in General
- Great for Systems with Limited USB Ports
- Old School Devices are Sturdy and Mechanical
1. Used By Enterprises For Security
Despite the declining use of PS/2 ports on consumer PC motherboards, the technology continues to find a home in the enterprise. One of the critical reasons for this is security.
Unlike USB, which can be infected with malware, PS/2 ports are much more difficult to tamper with.
For this reason, PS/2 ports are often used on servers and other high-security computers
2. Gamers Love The Low Polling Rate And N Key Rollover
We’re not sure why motherboard manufacturers still include PS/2 ports on their boards, but there are a few possible explanations:
- Some gamers love the low polling rate and N key rollover that PS/2 keyboards offer.
- PS/2 ports are still required for some legacy devices.
- Manufacturers may be just trying to hedge their bets in case PS/2 becomes popular again.
3. Great With BIOS, PC Hardware In General
PS/2 ports are the most reliable way to connect a mouse and keyboard to a PC.
They are much more reliable in communicating with the PC on the hardware level, meaning that while USB keyboards and mice can present a myriad of compatibility and driver issues, PS/2 keyboards and mice are simply plug-and-play.
4. Great For Systems With Limited USB Ports
The PS/2 port is an excellent addition to systems with limited USB ports. The PS/2 port can be used for some devices, including a keyboard, mouse, or even an external hard drive.
So, if you ever find yourself in a situation where you need to add an extra device to your system but don’t have a spare USB port, the PS/2 port is a great option!
5. Old School Devices Are Sturdy And Mechanical
The reason that PS2 ports are still popular is that they are mechanical devices. This means that they don’t rely on software to function correctly.
USB ports, on the other hand, are entirely software-based. This can be a problem if there are compatibility issues with the operating system or the drivers are not up to date.
Should I Use PS/2 Peripherals, Then?
Yes. PS/2 ports are still used on most computers, offering a few advantages over USB ports. For one thing, PS/2 peripherals don’t need drivers, so they’re easier to use.
They’re also less likely to cause interference with other devices and are not as easy to disconnect accidentally.
Can You Convert A PS2 To A USB?
No, you cannot convert a PS2 to a USB. PS2 uses a different type of connector than USB, so the two are incompatible.
Final Words
In conclusion, motherboard companies still have PS2 ports because they are needed for backward compatibility with older games and software.
It benefits those who want to keep their old hardware but may not have the money to purchase a new one.
