A serial line analyzer is a device similar to a logic analyzer but specialized for RS-232's voltage levels, connectors, and, where used, clock signals; it collects, stores, and displays the data and control signals, allowing developers to view them in detail.
Devices on a FireWire bus can communicate by direct memory access (DMA), where a device can use hardware to map internal memory to FireWire's physical memory space. The SBP-2 (Serial Bus Protocol 2) used by FireWire disk drives uses this capability to minimize interrupts and buffer copies. In SBP-2, the initiator (controlling device) sends a ...
The connectors the USB committee specifies support a number of USB's underlying goals, and reflect lessons learned from the many connectors the computer industry has used. The female connector mounted on the host or device is called the receptacle, and the male connector attached to the cable is called the plug.
It is intended to enable communication using the Universal Serial Bus (USB) protocol to be performed over a wide range of physical communication media, including WiFi and WiGig wireless networks. [21] The protocol is being developed from the base of the Wi-Fi Alliance's previous WiGig Serial Extension specification. [22] [23]
Keyboard and mouse cables and ports are almost invariably serial—such as PS/2 port, Apple Desktop Bus and USB. The cables that carry digital video are also mostly serial—such as coax cable plugged into a HD-SDI port, a webcam plugged into a USB port or FireWire port , Ethernet cable connecting an IP camera to a Power over Ethernet port, FPD ...
For isochronous devices like audio streams, the bandwidth is constant and reserved exclusively for a given device. The bus bandwidth therefore only has an effect on the number of channels that can be sent at a time, not the speed or latency of the transmission. Low speed (LS) rate of 1.5 Mbit/s is defined by USB 1.0. It is very similar to full ...
Today, the parallel port interface is virtually non-existent in new computers because of the rise of Universal Serial Bus (USB) devices, along with network printing using Ethernet and Wi-Fi connected printers. The parallel port interface was originally known as the Parallel Printer Adapter on IBM PC-compatible computers.
The SIO connector used sprung metal leaves to make a firm connection to the pins in the devices. The slots cut into the connector give the leaves room to move. The Atari 850 provided Centronics printer and RS-232 serial ports to connect to 3rd party devices. Typical of SIO devices, it has both in and out ports to allow daisy chaining.
