This page covers advantages and disadvantages of Serial Interface. In serial communication data bits are transmitted one after the other in. PISO and SIPO shift registers are used to convert serial data into parallel data and vice versa.

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 Are fast - useful for obtaining very recent unpublished information.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.

Ganguro girl full version. 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.

Definition Data Transmission: When we enter data into the via keyboard, each keyed element is encoded by the electronics within the keyboard into an equivalent binary coded pattern, using one of the standard coding schemes that are used for the interchange of. To represent all characters of the keyboard, a unique pattern of 7 or 8 bits in size is used.

The use of 7 bits means that 128 different elements can be represented, while 8 bits can represent 256 elements. A similar procedure is followed at the receiver that decodes every received binary pattern into the corresponding character. The most widely used codes that have been adopted for this function are the Extended Binary Coded Decimal (EBCDIC) and the American Standard Code for Information Interchange codes (ASCII). Both coding schemes cater to all the normal alphabetic, numeric, and punctuation characters, collectively referred to as printable characters and a range of additional control characters, known as non-printable characters. Data transmission refers to the movement of data in form of bits between two or more digital devices. This transfer of data takes place via some form of transmission media (for example, coaxial cable, fiber optics etc.) Types of Data Transmission Parallel transmission Defination: Within a computing or communication device, the distances between different subunits are too short.

Thus, it is normal practice to transfer data between subunits using a separate wire to carry each bit of data. There are multiple wires connecting each sub-unit and data is exchanged using a parallel transfer mode. This mode of operation results in minimal delays in transferring each word.

• In parallel transmission, all the bits of data are transmitted simultaneously on separate communication lines. • In order to transmit n bits, n wires or lines are used. Thus each bit has its own line. • All n bits of one group are transmitted with each clock pulse from one device to another i.e. Multiple bits are sent with each clock pulse. • Parallel transmission is used for short distance communication.

• As shown in the fig, eight separate wires are used to transmit 8 bit data from sender to receiver. Advantage of parallel transmission It is speedy way of transmitting data as multiple bits are transmitted simultaneously with a single clock pulse. Disadvantage of parallel transmission It is costly method of data transmission as it requires n lines to transmit n bits at the same time.
