What is LPT and COM port?
of you computer? COM ports can be used to connect peripheral devices and LPT port are specifically used for connecting printers. There settings in the BIOS and Windows depend up on the system manufactures.
What is the application of a parallel port?
Parallel ports provide an interface to connect multiple lines to prepare a parallel communication to send large data at a time. Parallel ports are used in connecting printers, hard-drives, CD-drives etc. All lines speed should be same to avoid error and cross-talk issues.
What is difference between serial port and parallel port?
The main difference between a serial port and a parallel port is that a serial port transmits data one bit after another, while a parallel port transmits all 8 bits of a byte in parallel. Computers have both serial and parallel ports along with newer technology called a USB (Universal Serial Bus) port.
What is parallel connector?
A parallel port is an interface allowing a personal computer (PC) to transmit or receive data down multiple bundled cables to a peripheral device such as a printer. A parallel port has multiple connectors and in theory allows data to be sent simultaneously down several cables at once.
What is parallel cable?
Filters. A series of metal wires that enable multiple bits of data to be transferred simultaneously. Parallel cables have mostly given way to serial cables, where data is transferred one bit after another.
What is the difference between COM and LPT ports?
LPT is a parrallel port typically associated with old printers. COM is a serial port assiciated with older interace devices like mice, PDAs, etc.
Why are parallel port important?
A parallel port is an external interface commonly found on PCs from the early 1980s to early 2000s. It was used to connect peripheral devices such as printers and external storage devices. It was eventually superseded by USB, which provides a smaller connection and significantly faster data transfer rates.
Is USB a COM port?
USB connections do not have com port numbers assigned to them unless its a usb-serial adapter which then it will assign a virtual com port #. Instead they have an address assigned to them.
