Today, we're diving into the PS/2 connector, a crucial component for connecting keyboards and mice to computers. Can anyone tell me what they know about it?
I know that PS/2 connectors are round and used for keyboards!
Great! Yes, PS/2 connectors have a circular design. They replaced older connectors like the DE-9. Why do you think that might have been?
Maybe because they were easier to use?
Exactly! The design allowed for simpler connectivity. Also, they feature an open-collector output for keyboards. What does that mean?
Could it be related to how they send information?
Yes! The open-collector output allows the keyboard to send signals when certain keys are pressed. Let's summarize that: PS/2 connectors are used for connecting keyboards and mice, using a unique circular design.

Now that we understand the basics, let's look at the technical specifications. Can someone explain what the pin configuration might look like?
They probably have multiple pins for different signals, right?
Correct! The PS/2 connector is designed with several pins, typically around 6, that manage different tasks like data and clock signals. Does anyone want to guess how many pins are used for a mouse compared to a keyboard?
I think both use the same number of pins.
That's a good thought! Actually, both devices use the same PS/2 connector but send different signals. The keyboard has an open-collector output while the mouse communicates differently. Let's remember that both mice and keyboards utilize these six pins.

To wrap this up, how do PS/2 connectors compare to USB ports, which are used more today?
USB connectors can be plugged in either way, but PS/2 only goes one way.
Excellent point! USB is more versatile with its plug-and-play feature. PS/2 requires specific orientation as well. Remember that PS/2 connectors were once the standard before USB became widely adopted. Would anyone like to summarize the key differences?
So, PS/2 is older, has a circular shape, and is not plug-and-play like USB?
Exactly! Great job! So remember, crank up that memory of the PS/2 connector's history, design, and differentiations.

Quick Overview
Standard
The PS/2 connector serves as an interface for keyboards and mice, notable for its design and functionality. Although they have largely been replaced by USB connectors, PS/2 interfaces were important in the evolution of computer peripherals.
Detailed
PS/2 Connector Summary
The PS/2 connector is a type of electrical connector used predominantly for connecting keyboards and mice to personal computers. It emerged as a standard when personal computers began to integrate more peripheral connections directly into their design, effectively phasing out older systems like the DE-9 and five-pin DIN connectors.
The PS/2 interface has a distinct physical design with a recessed and round shape that accommodates a mini-DIN plug, making it easy to identify. Key characteristics include the open-collector output for keyboards, which facilitates the connection and communication with PCs, ensuring smooth functionality. Despite its gradual replacement by USB connectors in modern devices, the PS/2 connector remains a critical part of computing history, and understanding its role provides insight into the evolution of computer hardware.

PS/2 connectors are used for connecting the keyboard and mouse to a personal computer.
Detailed Explanation
PS/2 connectors are a type of interface used to connect input devices, specifically keyboards and mice, to a computer. They allow these devices to communicate with the computer and transfer input data effectively. The design of a PS/2 connector is specific to the keyboard and mouse; they resemble each other closely but have functional differences.
Examples & Analogies
Think of PS/2 connectors like different types of outlets for electronic devices. Just like there are specific wall sockets for certain devices, PS/2 connectors are specially designed to fit keyboards and mice so they can 'plug in' and work with the computer.
Differences Between PS/2 Mouse and Keyboard Connectors

The PS/2 mouse and PS/2 keyboard connectors are similar to each other, except for the fact that the PS/2 keyboard connector has an open-collector output.
Detailed Explanation
While both PS/2 connectors look alike, they serve different functions based on their design. The PS/2 keyboard connector specifically has an open-collector output. This means that it can pull the output line low, but requires another device or circuit to drive it high. This feature is different from the PS/2 mouse connector, which is designed for different communication types. Understanding these differences is important for proper connection and functionality.
Examples & Analogies
Consider two types of garden hoses that you might haveβone has a nozzle that sprays water while the other simply lets water flow continuously. Even if they look similar, their purposes are different. The PS/2 connectors serve different devices, much like those hoses serve different functions in your garden.
Replacement of Older Connectors

PS/2 mouse and keyboard connectors have replaced the DE-9 and five-pin DIN connectors respectively.
Detailed Explanation
Over time, technology evolves and replaces older standards with newer, more efficient ones. The PS/2 connectors were introduced as improvements over the previous DE-9 and five-pin DIN connectors. This replacement was due to various factors including reliability, ease of use, and compatibility with modern computers. The PS/2 standard provided a simpler, more reliable way to connect input devices to computers.
Examples & Analogies
Imagine upgrading your old flip phone to the latest smartphone. The new smartphone has more features, a better interface, and is more compatible with the latest apps and services. Similarly, the PS/2 connectors brought enhancements and improvements over their older counterparts, making them the preferred choice for connecting keyboards and mice.
Physical Characteristics

Figure 15.30 shows the PS/2 connector with the pin details.
Detailed Explanation
The PS/2 connector has a specific physical structure characterized by its round shape and pins that connect to the corresponding ports on the devices. Each pin has a designated function, allowing the correct transmission of signals between the computer and the keyboard or mouse. Understanding how many pins and their specific layouts can help in properly making connections and troubleshooting if issues arise.
Examples & Analogies
Think of a PS/2 connector like the key to a lock. Just as a key is shaped to fit into a specific lock, the pins of the PS/2 connector are precisely configured to fit correctly into their respective sockets so that everything works smoothly without confusion.
