How many serial and parallel ports are available?
Any entry level computer has at least 6 USB ports. 4 at back and 2 at front side of CPU unit. Usually there is at least one serial port. And usually there is 1-3 parallel ports…
What are serial and parallel ports?
A serial port is capable of delivering the single stream of data. While a parallel port is capable of delivering multiple streams of data. 5. Serial port send a bit after another bite at a time. While parallel ports send multiple bits at once.
What are serial and parallel ports used for?
Serial Port is used for serial data transmission. Parallel Port is used for parallel data transmission. Transmission speed of a serial port is slow as compared to a parallel port. Transmission speed of a parallel port is quiet high as compared to a serial port.
What is the difference between parallel and serial ports?
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. Thus a parallel port transmits data much faster than a serial port.
Is USB parallel or serial?
While interfaces such as Ethernet, FireWire, and USB also send data as a serial stream, the term serial port usually denotes hardware compliant with RS-232 or a related standard, such as RS-485 or RS-422.
What is serial port parallel port?
A serial port sends data bit by bit after sending a bit at a time. A parallel port sends data by sending multiple bits in parallel fashion. Modems, security cameras, device controllers use serial ports. Printers, Hard Drives, CD drives use parallel ports.
What are the different types of serial communication?
There are two broad types of serial communication: synchronous and asynchronous. There are a very large number of different standards and protocols for serial communication, ranging from the very simple to the seriously complicated.
What are the different types of serial communication protocols?
Similarly there are several examples of Serial Communication Protocols such as CAN, ETHERNET, I2C, SPI, RS232, USB, 1-Wire, and SATA etc.
