Advantages Of Serial Communication Over Parallel Communication

The advantages of oral channels of communication are that they:. Are fast - useful for obtaining very recent unpublished information. Are based on two-way communication and therefore promote an understanding of the real information need(s) and the communication of relevant information.

The advantages and disadvantages of serial links in communication system design. 5) Differential serial links can drive longer distance than parallel buses and are less susceptible to noise. 6) Circuit board routing is simpler, as only two serial lines need to be routed, replacing a wide bus and the associated clock. Define serial and parallel transmission methods and discuss the advantages of. Serial transmission: data bits are sent one bit at a time over a single wire.

Ar e flexible. Simplify and facilitate the transmission of information between people working in different subject areas (useful in interdisciplinary studies). Are easy and pleasant to use The disadvantages of oral channels of communication are that they:. Are not open to everyone - established researchers have access to good networks of contacts, but these usually take time to cultivate.

Can lead to misconceptions because the information is sometimes incomplete (lack of detail etc.). Are difficult to maintain and therefore unstable.

It can also lead to mis belief,as oral promises do not lend any where. As a human nature one can make mistake in spelling something different which can sometimes leads to major mistake. Some of the advantages of verbal communication are: 1) the opportunity for immediate feedback to make sure the message was understood; 2) the opportunity to utilize nonverbal cues (tone, body language, inflection) However, there are several disadvantages and the main one is miscommunication. I n other words, what the listener hears is often not what is meant. The simplest words, for example, have a different connotation for people. Psychologists trace it to one's upbringing, social status, family and friends, etc.

Generally speaking, men are adverse to expressing their feelings, and hide behind enthusiastic talk about sports, women and cars. Women are often more observant and intuitively separate the truth in a conversation. Advantages of community college. Less expensive way to earn college credits for all those non-major courses you'll have to take anyway (English, Math, Sociology, Physical Education, etc.).

Usually within an acceptable commute from home so you save on paying for housing and board. Since you can commute from home, you may be able to hold on to that part-time job you like and take classes. If you struggled in high school and didn't have the grade point average for the college you really wanted, community college gives you a second chance at earning those grades and re-applying.

There are two ways to transfer data between computers: Serial Transmission and Parallel Transmission.

Serial Transmission Data is sent bit by bit from one computer to another in two directions. Each bit has a clock pulse rate. Eight bits are transmitted at a time with a start and stop bit known as a parity bit, which is 0 and 1 respectively. Data cables are used when transmitting data to a longer distance.

The data cable has D-shaped 9 pin cable that connects the data in series. Categories of Serial Transmission Asynchronous transmission – an extra bit is added to each byte to alert the receiver on the arrival of new data. 0 is used as a start bit while 1 used as a stop bit. Synchronous transmission – no extra bit is added to each byte. Data is transferred in batches which contains multiple bytes. Parallel Transmission Several bits are transmitted together simultaneously with one clock pulse rate.

It transmits quickly as it utilizes several input and output lines for sending the data. It uses a 25-pin port with 17 signal lines and 8 ground lines.

The 17 signal lines are divided as • 4 lines – initiates handshaking • 5 lines – communicates and notifies errors • 8 lines – transfers data Applications Serial transmission occurs between two computers or from a computer to an external device located some distance away. Parallel transmission can take place within a computer system, through a computer bus or to an external device located a close distance away. Examples An example of serial mode transmission include connection between a computer and a modem using the RS-232 protocol. An RS-232 cable can accommodate 25 wires, but only two of these wires are for data transmission, the rest are for overhead control signaling. The two data wires run on simple serial transmission in either direction.
