## FAQs
### Q: What is a PS/2 corded mouse?
A: A PS/2 corded mouse is a hand-held computer pointing device that connects to a computer via a PS/2 port using a physical cable. It is used for precise cursor control on computer displays.

### Q: How does a PS/2 corded mouse connect to a computer?
A: A PS/2 corded mouse connects to a computer through a PS/2 port using a physical cable. This connection type was common in older computer systems.

### Q: What are the advantages of using a PS/2 corded mouse?
A: PS/2 corded mice offer reliable connectivity and do not require batteries, as they draw power directly from the computer through the PS/2 port. They are also less prone to interference compared to wireless mice.

## Why It Matters
PS/2 corded mice played a significant role in the evolution of computer input devices. They provided a reliable and cost-effective method for users to interact with graphical user interfaces, which became increasingly important as personal computers gained popularity in the 1980s and 1990s. The PS/2 interface, introduced by IBM in 1987, offered a standardized connection method that improved upon earlier serial and parallel port connections. While USB has largely replaced PS/2 ports in modern computers, PS/2 corded mice remain relevant for users who prefer their reliability or need to connect to legacy systems. Their continued use in certain applications, such as gaming and professional environments, demonstrates their enduring value in specific contexts.

## Notable For
- Reliable wired connection via PS/2 port
- No battery requirement, powered directly from computer
- Less susceptible to interference compared to wireless alternatives
- Compatibility with legacy systems and certain specialized applications
- Standardized connection method introduced by IBM in 1987

## Body
### History and Development
The PS/2 corded mouse emerged as a refinement of the original computer mouse concept, which was first developed in 1963. The PS/2 interface, introduced by IBM in 1987 as part of their Personal System/2 computers, provided a standardized connection method for both keyboards and mice.

### Technical Specifications
PS/2 corded mice typically use a 6-pin Mini-DIN connector, although some variations exist. They communicate with the computer using a serial protocol, sending data about movement and button clicks. The mice are usually powered through the PS/2 port, eliminating the need for batteries.

### Usage and Applications
PS/2 corded mice have been widely used in office environments, educational institutions, and home computers. They are particularly valued in situations where wireless interference might be problematic or where a constant, reliable connection is crucial. Some gamers and professionals in fields such as graphic design continue to prefer PS/2 mice for their perceived responsiveness and reliability.

### Advantages and Limitations
The primary advantages of PS/2 corded mice include their reliability, lack of need for batteries, and resistance to wireless interference. However, they are limited by the availability of PS/2 ports on modern computers, which have largely transitioned to USB connections. Additionally, PS/2 mice typically do not support hot-plugging, requiring the computer to be restarted if the mouse is disconnected and reconnected.
