The doorway through which your modem, mouse and other such devices are connected to your computer. Also known as COM ports. Distinct from PARALLEL POERTS ( usually used with printers ) which transmit data over several channels simultaneously.
A comparatively old interface for connecting devices to the computer that allows the transfer of relatively little data in a given amount of time. The serial port is mainly used with mice and external modems, but it is also sometimes used with digital cameras to transfer picture files.
A computer input/output port that transmits data sequentially, one bit at a time. The serial ports on the back of your computer are the DB-9 and DB-25 Male connections. (DB connectors are the 'D-shaped' ports).
A computer interface that communicates with an external device such as a printer. In serial mode, data is sent one bit at a time through one wire. Serial transfer is slower than parallel, but can be accomplished effectively over much longer distances, i.e. 20 feet or more.
The "male" connector (usually DB-9 or DB-25) on the back of your computer. It sends out data one bit at a time. It is used by modems and, in years past, for daisy-wheel and other printers. The other port on your computer is the parallel port, which is a "female" connector. It is used for printers, backup systems, and mini-networking (LANs). See also COM.
A port on the PC that handles a data stream in a serial mode. That is, the data is sent out or received one bit at a time on a single line or connector pin. Other lines or pins may be used for handshaking or data transfer control. A serial port is normally set up to operate in a bidirectional data transfer mode using two data lines (one for each direction of data flow).
(Or "com port") A connector on a computer to which you can attach a serial line connected to peripherals which communicate using a serial (bit-stream) protocol. The most common type of serial port is a 25-pin D-type connector carrying RS-232 signals. Smaller connectors (e.g. 9-pin D-type) carrying a subset of RS-232 are often used on personal computers. The serial port is usually connected to an integrated circuit called a UART which handles the conversion between serial and parallel data.
An input/output channel for serial data communication. A serial port is the connection point on a computer where you connect a serial device to the system, such as a mouse or external modem. Serial ports are typically identified as communication (COM) ports. Most computers come with two serial ports, and many have the capacity to accommodate four or more.
Communications path through which data is transferred in bytes. Only one wire each is available for transmitted and received data; character bits are sent sequentially between two nodes, one at a time.
A socket for plugging devices into the computer (not the same as USB). Most PCs have two, called COM1 and COM2. Most often used to plug in a modem or mouse; however, on many modern computers a modem is built into the computer as an expansion card, and the mouse has its own separate port.
Serial ports are used for non-demanding communications between your computer and other external devices (example: modems, printers, digital cameras, etc.). Serial ports operate at speeds up to 115Kbps (115,000 bits per second).
Serial ports are generally used to pass information one way to your computer. Your mouse and keyboard use Serial ports as no information is passed back to the mouse or keyboard, as opposed to Parallel ports which pass information back to the devices.
A computer I/O (input/output) port through which the computer communicates with the external world. The standard serial port is RS-232 based and allows bidirectional communication on a relatively simple wire connection as data flow serially.
The interface on a computer that allows asynchronous transfer of data one bit at a time. Serial port on a PC usually follows RS-232C standard and has DB-9 or DB-25 male connector. Also known as communication or COM port. See picture. Also see parallel port.
A socket on a computer that is used to connect a modem, mouse, scanner, or serial printer. Sometimes two computers are connected together by their serial ports to send data between them. A serial port sends information through a cable one bit at a time, whereas a parallel port sends eight bits at a time along parallel wires. A parallel port sends data faster but a serial port is reliable for transmission over a longer distance.
data port/connection standard that is usually used to connect modems and mice. It comes in 9- and 25-pin varieties, both of which effectively function the same way. Serial ports are largely being eliminated in favor of much faster USB and FireWire connection standards.
A variety of devices attach to a computer via the serial port. On a PC, the port provides a connection for a mouse, a modem and other types of input devices. Apple's Macintosh machines commonly use the serial port for a printer Connection.
A connector on PC peripherals and networking devices that is used to perform serial communication. Serial communication is one of the data transfer methods utilized by computers and their peripherals. In serial communication, one bit of data is transmitted at a time through one signal line. This scheme has been standardized by EIA (Electronic Industries Association), and the RS-232C standard is now most widely used. Most computers today are equipped with one or more RS-232C ports, and they are used to establish connections between the computers and their peripherals including printers, modems and scanners. The RS-422 standard is an enhanced version of the RS-232C, and Macintosh computers are equipped with this port. The RS-422 provides downward compatibility to all RS-232C products. Other serial interfaces available today include the IrDA, USB and IEEE1394 standards.
This is the 9 or 15 D-type connector at the rear of the computer that serial peripheral devices like mice, modems, early printers, bar code readers etc. can be connected to. Modern computers may either use a high speed serial bus containing a 16550 family of serial port chips or even use USB. See also Mouse, Modems, Printers, Peripherals and USB.
A nine- or 25- pin male port found on the back of a computer, which, via an RS-232C cable, connects to the serial port on a modem. Most computers have two serial ports, COM1 and COM2. A computer's serial ports are run by UART chips, which come in different speeds.
A male 9-pin or 25-pin port on a computer system used by slower I/O devices such as a mouse or modem. Data travels serially, one bit at a time through the port. Serial ports are sometimes configured as COM1, COM2, COM3 or COM4.
A full-duplex channel that sends and receives data at the same time. It consists of three wires, two that that move data one bit at a time in opposite directions and a third wire that is a common signal ground wire.
The Serial Port facilitates asynchronous (two way) data transmission. It is also known as a communication port or COM port. A computer can have up to 4 serial ports but because each pair calls on the same hardware resources, you can only use two at a time.
an interface, that can be used for serial communication, in which only 1 bit is transmitted at a time. A serial port is a general-purpose interface that can be used for almost any type of device, including modems, mice, and printers (although most printers are connected to a parallel port). This technology is being replaced by USB and firewire technology.
An input/output connection on the computer that allows it to communicate with other devices in a serial fashion-data bits flowing on a single pair of wires. The serial port is used with RS-232 protocol.
A serial port is an input/output port of a computer used to connect a serial device with a serial interface. Earlier computers used the serial port for the mouse and printers. Computers now use USB ports instead of serial ports.
A serial port is an asynchronous communication channel or address to which a peripheral device such as a modem, a character printer, or a mouse, can be connected. Serial ports are also referred to as COM ports, (COM1, COM2, etc.) With serial communications, bits of data are transmitted one at a time over a single line as opposed to parallel communications where multiple wires in the cable allow data to be sent in multiple bits. Serial interfaces are also called RS-232.
An interface on a computer that supports transmission of a single bit at a time; can be used for connecting almost any type of external device including a mouse, a modem, or a printer (although most printers are connected to a parallel port). On personal computers, most serial ports use an RS-232C or RS-422 type connector.
In computing, a character is represented by a binary number (byte), typically made up of eight binary digits (bits). A serial port is a connector where information is made available and can be read one binary digit (or bit) at a time. Therefore 8 bits need to be read in order to obtain each character. See also parallel port.
A very slow port on the computer used mainly by modems. Many digital cameras come equipped with cable to download images through this port but it's slow! Both parallel and USB ports are faster connections.
In computing, a serial port is a serial communication physical interface through which information transfers in or out one bit at a time (contrast parallel port). Throughout most of the history of personal computers, data transfer through serial ports connected the computer to devices such as terminals or modems. Mice, keyboards, and other peripheral devices also connected in this way.
