Two computer questions, those who learn computer come in and answer a few questions

I'm not a professional, but I'm interested in your question, so I'd like to give my personal opinion:

1. For this problem, I think it is necessary to either expand the receiver's receptivity or reduce the sender's ability to send to bring them to a state of equilibrium.

2, I think it can be roughly divided into wireless network, wired network. They work differently.

1. If the receiver's NIC has a larger throughput, the data is based on the smaller throughput during the transmission process.

The second way of working is not understood. Is it a Frame Relay Network, an ATM Network, this kind of thing?

35(1) Output 2

Process fun(7) = 7-fun(5).

fun(5)=5-fun(3)

fun(3)=3-fun(1)

fun(1)=3

Layer by layer returns to get fun(7)=2

2) By the same token, output 6

56(1) output.

The process x*100+, converted to int, becomes 12346, and then divided by (2) The comma expression has a lower priority than the assignment statement, firstly, calculate a+=a-=5 according to the right combination, a=a-5=-5

a=a+5=-10

c gets -10

Then the following expression is evaluated.

a=b=0, b+3=3, but no value is assigned.

So the end result is 0, 0, -10

3) Output Result 1

Procedure axx62 output 4 5 99

Process B so a=c=5, c=t=99

a, so the result is a=4, b=5, c=99

Upstairs, I really dare to stick it out...Select: disks, hard disks are external storage5I'm not sure, it's not good to tell you that the extension can not be specific for login** only need a username and password 10ce multiple choice questions:

1 False, 2 False, 3 True, 4 True, 5 False, 6 False, 7 True, 8 True, 9 False, 10 False.

abcdefg right wrong wrong right wrong wrong.

Divide 1676 into 16,76

Find the hexadecimal system of 16 and 76, which are 10 and 4c, respectively, and add up to 104c.

104CH+2020H=306CH (national standard code = location code +2020H).

You get the decimal conversion wrong decimal to hexadecimal is divided by 16 remainder.

The area code 1676 needs to be divided into two parts: the high-byte bit 16 and the low-byte bit 76.

1. In the following account of the world's first electronic computer, ENIAC, the error is D

a.The world's first computer was born in the United States in 1946It mainly uses electron tubes as the main electronic device.

c.It is mainly used for military purposes and scientific calculations, such as ballistic calculations dMake sure to use a high-level language for programming.

Analysis] ENIAC is the English abbreviation of the first electronic computer.

It was only from the second generation of computers that the high-level programming languages such as basic and fortran were introduced, so D is wrong.

Yes, D and A are right, and they are in the textbook;

b is also correct, the second generation of computers only began to use transistors, and the first generation was all electron tubes;

C Yes, the original computer was used for military and scientific computing, with the emergence of high-level languages in the second generation of computers, the application field of computers has been greatly expanded, so that computers are not used for scientific computing, but also used for data processing and transaction processing, and gradually used for industrial control.

Just do this question (

1. The transmission rate of the code element is limited by the Nyehl's criterion, and the information transmission rate is limited by the Shannon formula, and the significance of the Shannon formula in data communication is that as long as the information transmission rate is lower than the limit transmission rate of the channel, the transmission without difference can be realized.

Bit s is a unit of information transfer rate.

The symbol transmission rate is also known as the modulation rate, waveform rate, or symbol rate. A symbol does not necessarily correspond to a bit.
