Perifériacsatlakozók, often referred to as peripheral connectors, are the interfaces on a computer that allow it to communicate with external devices. These connections enable the transfer of data and power between the central processing unit (CPU) and peripherals such as keyboards, mice, printers, monitors, and external storage devices. Over time, various types of peripheral connectors have evolved to meet changing technological demands for speed, functionality, and ease of use.

Historically, serial and parallel ports were common. Serial ports, like the RS-232, transmitted data one bit at a time, making them slower but more versatile for certain applications. Parallel ports, on the other hand, transmitted multiple bits simultaneously over separate wires, offering higher data transfer rates for devices like printers.

More modern connectors have largely replaced these older standards. USB (Universal Serial Bus) has become ubiquitous due to its versatility, hot-pluggability (allowing devices to be connected and disconnected while the computer is running), and ability to provide power. USB comes in various versions (e.g., USB 2.0, USB 3.0, USB-C), each offering increasing speeds and functionalities.

For video output, HDMI (High-Definition Multimedia Interface) and DisplayPort are now standard, supporting high-resolution displays and audio signals. Older connectors like VGA and DVI are still found on some devices but are gradually being phased out. Other specialized connectors exist for specific purposes, such as Ethernet for network connectivity and audio jacks for sound input and output. The choice of connector is crucial for ensuring compatibility and optimal performance between a computer and its peripherals.
