what is the difference between serial and parallel transfer?

In Serial Transmission, data-bit flows from one computer to another computer in bi-direction. ... In Serial Transmission, 8 bits are transferred at a time having a start and stop bit. Parallel Transmission: In Parallel Transmission, many bits are flow together simultaneously from one computer to another computer.

The transfer took close to 3 hours. In most cases the transfer will not take that long but for those of you with many files it may be over an hour to copy all that data to the new computer.

One key difference between the two cables is their pinouts. A USB 2.0 can only have as many as 4 or 5, but a USB 3.0 has 9. This is one of the main reasons a USB 3.0 cable can offer much more transfer rate than your USB 2.0.

Baud rate is commonly used when discussing electronics that use serial communication. In the serial port context, "9600 baud" means that the serial port is capable of transferring a maximum of 9600 bits per second. At baud rates above 76,800, the cable length will need to be reduced.

There are several types of serial communication depending on the type of transmission mode and data transfer. The transmission modes are classified as Simplex, Half Duplex and Full Duplex. Simplex Method: In simplex method either of the medium i.e sender or receiver can be active at a time.

A Serial port is an asynchronous port on the computer used to connect devices serially to the computer. ... A USB is a standard cable connection interface between personal computers and electronic devices of consumer. USB allows the USB devices to be connected to each other and transfer digital data over the cable.

Simply, a UART is a serial port, but a serial port is not neccessary a UART. Serial port is a general term for anything serial, without further specification, while a UART defines a tranceiver for a specific asynchronus format.

So while a UART may help you implement an RS-232 interface, it is not an RS-232 interface itself. The UART functions to convert parallel data from PC bus lines to serial data for transmission via line drivers to RS-232, RS-422, and RS-485 devices. The clock pin of the UART chip is feed by a programmable clock source.

Serial data transmission sends data bits one after another over a single channel. Parallel data transmission sends multiple data bits at the same time over multiple channels.

Serial ports rely on a special controller chip, the Universal Asynchronous Receiver/Transmitter (UART), to function properly. The UART chip takes the parallel output of the computer's system bus and transforms it into serial form for transmission through the serial port.

Abstract. Serial and parallel processing in visual search have been long debated in psychology, but the processing mechanism remains an open issue. Serial processing allows only one object at a time to be processed, whereas parallel processing assumes that various objects are processed simultaneously.

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.

With DMA, the CPU first initiates the transfer, then it does other operations while the transfer is in progress, and it finally receives an interrupt from the DMA controller (DMAC) when the operation is done. ... DMA is also used for intra-chip data transfer in multi-core processors.

PCI Vs PCI Express in Working Topology: PCI is a parallel connection, and devices connected to the PCI bus appear to be a bus master to connect directly to its own bus. While PCIe card is a high-speed serial connection. ... PCI Vs PCI Express in Others: With PCI Express, a maximum of 32 end-point devices can be connected.

Serial ATA is the connection/connector interface while ATA-8 is the protocol for that interface. IDE was the interface and it also used an ATA protocol for communication. IDE and ATA are not the same thing, just as SATA and ATA are not the same either. ... SATA is a Serial ATA connection.

The main difference between IDE and SATA is that the IDE provides a parallel connection to connect the storage device to the computer bus while SATA provides a serial connection to connect the storage derive to the computer bus.

RS232 is the definition of the serial interface, e.g. the signal voltage and duration. DB9 is the 9 pin connector. RS232 connections are frequently implemented using these connectors, but there is a 25 pin connector also.
