ace level (i.e. the complement of a mark) for one element period. This element is called the start bit and has a duration of T seconds. The transmitter then sends the character, l bit at a time, by placing each successive bit on the line for a duration of T seconds, until all bits have been transmitted. Then a single parity bit is calculated by the transmitter and sent after the data bits. Finally, the transmitter sends a stop bit at a mark level (i.e. the same level as the idle state) for one or two bit periods. Now the transmitter may send another character whenever it wishes.
At the receiving end of an asynchronous serial data link, the receiver continually monitors the line looking for a start bit. Once the start bit has been detected, the receiver waits until the end of the start bit and then samples the next N bits at their centers, using a clock generated locally by the receiver. As each incoming bit is sampled, it is used to construct a new character. When the received character has been assembled, its parity is calculated and compared with the received parity bit following the character. If they are not equal, a parity error flag is set to indicate a transmission error.

A.places the line in a space level

(2).Then a single parity bit is calculated by the transmitter and ().
A.compared with the received parity bit
B.sent with the data bits
C.sent after the data bits
D.sent before the data bits
(3).At the receiving end of an asynchronous serial data link, the receiver continually monitors the line().
A.waiting for the end of the start bit
B.looking for a start bit
C.generating a clock
D.constructing a new character
(4).When the transmitter wishes to send data , it first sends().
A.a character at the same time
B.a character to the line
C.the start bit
D.a mark level to the line
(5).The transmitter then send the character, for a duration of T seconds().
A.each bit
B.all bits
C.successive bits
D.a start bit and a character

Actually, soaps are more than a college favorite; they’re a youth favorite.When school is out, high-school students are in front of their TV sets.One young working woman admitted that she turned down a higher paying job rather than give up watching her favorite serials.During the 1960’s, it was uncommon for young people to watch soap operas.The mood of the sixties was very different from now.It was a time of seriousness, and talk was about social issues of great importance.
Now, seriousness has been replaced by fun.Young people want to be happy.It may seem strange that they should turn to soap opera, which is known for showing trouble in people’s lives.But soap opera is enjoyment.Young people can identify with the soap opera character, who, like the college-age viewer, is looking for happy love, and probably not finding it.And soap opera gives young people a chance to feel close to people without having to bear any responsibility for their problems.
