In Parallel Transmission, every bit needs a wire to transfer data from one place to another. For instance, n number of bits need n number of wires. Advantage: Its transfer speed is theoretically higher than with serial, since entire bytes or more can be transmitted at once. Disadvantages: Cross-talk can be a problem at higher rates of speed. That is why PATA drives cannot be clocked past 133 MB/S.
Feb 22, 2012 - information on the LCD using different parallel or serial protocol interfaces. Only one protocol. Transmitted at the same time. In serial mode, the bits are transmitted as a series of. The biggest advantage of the serial interface. SPI (3 wire) uses Serial Data Out, Serial Data In, and Serial Clock. Both Serial and Parallel Transmission have their advantages and disadvantages respectively. Parallel Transmission is used for shorter distance, provides greater speed. On the other hand, Serial Transmission is reliable for transferring data to longer distance.
Also, there can be many wires, and the more wires involved, and the higher the speed, the more cross-talk. Also, if the wires are of different lengths, signals can get out of sync, and the bits can become skewed.
In Serial Transmission, one bit follows other,so we need only one communication channel rather than n to transmit data between two communicating devices. Advantages: Since it uses only one communication channel, it reduces the cost of transmission over parallel by roughly a factor of n. Cross-talk and skewing are not problems since the data is transmitted on only 1-2 signal wires. Disadvantage: In theory, it is slower than for parallel transmission. However, due to a lack of cross-talk, it can be clocked much faster.
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 Are fast - useful for obtaining very recent unpublished information.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. 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.
Dupe hack for mu seasons. 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.
