Parallel computing is when you do a lot of different things at once, a graphics card is a parallel processor. The main CPU is a serial processor, it does one thing, but does it really fast, then switches to another. Video editing works better on a parallel processor, for you can encode different frames all at the same time, instead of working on one, then moving on to the next.

What is the advantage of SAS over parallel SCSI?
SAS is SCSI, it connects via a serial cable/connector instead of parallel (long and skinny) connector.
What is difference between a parallel bus and a serial bus?
A Parallel bus has a relatively large number of wires bundled together that enable data to be transferred in parallel. This increases the throughput, or rate of data transfer, between the peripheral and the computer. A Serial bus can be defined as a transmission path over which the participants transmit their data serially, sequentially in time, and using a common medium. In the case of serial transmission, only a single communication link for transferring data from any given end to another one. In the case of parallel transmission, we use multiple numbers of parallel links for the simultaneous transmission of all the data bits in the network.
Why is ubs put an improvement over serial parallel parts?
One of the major advantages of USB over Serial/Parallel ports is the increase of speed between the device and your computer. Also, USB devices can be chained together so one USB port can be used by many devices. Lastly, USB is considered "hot swappable" - therefore your computer can easily disconnect one device and discover a new one that you have plugged in.
What advantage do computer models have over physical models?
alot
What are the advantages and disadvantages of parallel change over?
advantage 1. Effective in Recognition and correction of errors.
What are the advantages and disadvantages of parallel and serial data transmission?
big advantage of parallel transmission is the factor of speed. All else being equal, parallel transmission can increase the transfer speed by a factor of n over a serial transmission. But there is also a very significant disadvantage of parallel transmission. And that is the factor of cost. It can be proved from the fact that the parallel transmission requires 'n'
Can a serial port send data over a longer distance than a parallel port?
Usually, because a serial port doesn't have to deal with the problem of signal skew that can jumble the data on a parallel port and gets worse proportional to distance.
Differences between serial and parallel interfaces?
The difference is that serial transmissions only use 2 wires for transmitting and receiving data, and only 1 for sending or receiving, and can only send one bit at a time. Parallel cables use several wires for data transmission and is much faster than serial thus 8 or more wires are carrying data *parallel* to each other to it's destination. serial data data (8 bits) transmit -----------010101010-----------------> single line to transmit on receive <--------------------------- single line to receive on Parallel data (80 bits) transmit multiple lines simultaneously ---- 010101001-----------> -----------010101010-----------> -----------010101010-----------> -----------010101001-----------> -----------010101010-----------> -----------010101010-----------> -----------010101001-----------> -----------010101010-----------> -----------010101010-----------> -----------010101001----------->
What do you mean by a serial interface?
Serial means that each bit in a data packet is sent over one wire, one after the other (in chronological order). This is the opposite of parallel, where many bits are sent at once over several wires.

What are the advantages and disadvantages of a serial port?
Having a serial port allows you to plug more stuff in you computer. i think The serial technology and the parallel technology are now old technology because of hardware like USB and Firewire. They are ports on the back of your computer. Serial ports transfers bits one at a time in a single file one bit at a time. Parallel ports transfers data 8 bits are a time across 8 wires. There are still serial ports on your computer, a serial port comes in 9 and 15 pins and is a male. Things that used to and sometimes still do connect to them are mice, external modems, PDAs and cameras. Parallel ports have 25 pins and is female. Most the time printers used to connect to parallel ports.The serial technology and the parallel technology are now old technology because of hardware like USB and Firewire.
