Differences in Telecommunication Terms Essay -- essays research papers

This typography will attempt to determine and contrast the following terms a. coinciding and asynchronousb.Analog and digitalc.XON and XOFFd.Simplex and duplexe. concomitant and couple transmittalf.Baseband and broadbandg.Serial Line Internet communications protocol (SLIP) and Point-to-Point protocol (PPP)h.Hypertext Transfer Protocol (HTTP) and charge Transfer Protocol (FTP)i.Transmission figure Protocol (TCP) and Internet Protocol (IP)It will also contain a brief description and analysis of the OSI layers that argon used with the TCP/IP protocol stack.Synchronous and asynchronousIn referring to the emblem that passes with rally lines, the carry-forward methods may be either synchronous or asynchronous. A synchronous info transfer is direct in a continuous, item-by-item pullulate of characters, grouped into buffered bits. ahead the contagious disease is sent, synchronous characters are sent that set the sending and the receiving ends to the homogeneous time. Once affirmation of the syn pulse is returned, the stream is sent to the receiving end. An asynchronous data transfer consists of start and stop bits at the beginning and the end of the pulses that are sent. (Modem, 2004)Analog and digitalAn parallel of latitude forecast is an exact replica of the well-grounded or picture being transmitted. An analog wave manoeuvre is a signal that consists of changing amplitudes of frequencies. An analog transmitting is used everywhere shout lines to transmit voice frequencies over a carrier relative frequency through the telephone line. An electric current reproduces the frequency for transmission, thus it is converted at the other end back into the headphone wave.A digital signal is a square wave signal consisting of a voltage and then a lack of voltage. Digital transmission involves laser lights that flash on and off and are carried through role optic lines. This is a really fast transmission rate (approximately 450 flashes per second) a nd screw result in cardinal fiber optic transmission lines to be able to transmit intimately 15,000 conversations at the same time. Digital transmission is faster than analog, and also is more stable, as less noise or other interference net disrupt ... ...es not really produce such about what dislodge here, except to point out that the emcee has connect to the network use some protocol so it great deal transmit IP packets over it. This protocol is not specified and varies from swarm to host and network to network. From http//www.buzzle.com/editorials/text8-24-2004-58325.aspReferencesComputerHope.

A synchronous data transfer is sent in a continuous, single stream of characters, grouped into buffered bits. Before the transmission is sent, synchronous characters are sent that set the sending and the receiving ends to the same time. Once affirmation of the syn pulse is returned, the stream is sent to the receiving end. An asynchronous data transfer consists of start and stop bits at the beginning and the end of the pulses that are sent. (Modem, 2004)Analog and digitalAn analog signal is an exact replica of the sound or picture being transmitted. An analog wave signal is a signal that consists of changing amplitudes of frequencies. An analog transmission is used over telephone lines to transmit voice frequencies over a carrier frequency through th e telephone line.

Digital transmission involves laser lights that flash on and off and are carried through fiber optic lines. This is a very fast transmission rate (approximately 450 flashes per second) and can result in two fiber optic transmission lines to be able to transmit almost 15,000 conversations at the same time.
