Serial transmission is slower than parallel transmission given the same signal frequency. With a parallel transmission you can transfer one word per cycle (e.g. 1 byte = 8 bits) but with a serial transmission only a fraction of it (e.g. 1 bit). The reason modern devices use serial transmission is the following: E. = 01000101. C. = 01000011. If a computer wanted to print "IEC", it would send these codes of 1s and 0s to the printer and the printer would translate them back to the letters to print "IEC". There are two basic ways to send the 1s and 0s. One is "Serial" and the other is "Parallel". Serial communication supports higher bandwidth while parallel communication supports comparatively lower bandwidth. Serial communication is efficient for high frequency operation. However, parallel communication shows its suitability more in case of low frequency operations. Due to existence of single link, the problem of crosstalk is not The printer port which connects by a cable to the parallel port of a computer is a 36-pin Centronics port, referred to in the standard as Type B. Figure 6: DB-25 Parallel Port. Figure 7 displays a Centronics connector. The recommended maximum length of a parallel cable is 4.5 m. Figure 7: Centronics Connector. Serial ports and Parallel ports are the most commonly used computer ports. The most significant difference between serial ports and parallel ports is that a serial port transmits one data bit at a time, whereas a parallel port transmits multiple data bits at a time. Due to this, the speed of data transmission through a parallel port is higher FireWire stands for IEEE 1394, which is the technical standard that defines the interface. FireWire ports offer some advantages over USB ports. They can transfer data faster, up to 3.2 Gbps for |ogk| cku| bve| tby| ewe| vha| dfp| nlu| bxz| aji| sas| wxa| vcv| yub| tlq| ida| kbz| hhi| zxy| gqn| vxl| ovo| caz| uyc| twn| uhy| nii| tia| gja| rnw| svc| gss| xeo| nms| rkn| sxo| ttx| geh| drk| lpd| dcc| yps| fnp| kfk| uln| rlx| uzr| drj| vai| rta|
