Emergency SOS Computer Professional Volunteer Questions!!

What the specific majors do, I don't know very well after I haven't been in China for a long time, guess it.

The general employment directions of many ** technologies are: electronic publishing, various advertising graphic design, animation, web design, etc.

Computer information management is probably database data analysis and processing, and so on.

Computer applications are probably programmers, and they don't make much sense.

Network development is a major trend, and no matter what products are in the future, they will be inseparable from the network. Universal.

In fact, as a person who has come before, I really hope that you can find something you like to do instead of looking at job prospects. To be honest, no matter what you study, you will face tremendous pressure to compete for jobs, and it is best to choose the four years of college that you are interested in, not only majors, but also lay a good foundation in all aspects, foreign languages, how to behave in the world, and all kinds of other skills, which are used for a lifetime.

Good luck.

Electronic information engineering technology is better, I am an undergraduate computer science and technology, I am interested in **, originally studied in this direction, but simple, the network was very popular before 2005, now it can't, the prospect of software is better, but boring.

A Chinese character occupies two bytes, and the amount of information in 800 characters is 800*2=1600 bytes=

It will take time.

The mail server is the sending mail server, and POP3 is the receiving mail server6The modem belongs to the first layer of the OSI model, which is the physical layer. The scope of work of the physical layer is the transmission of the original bit stream, the transmission of electronic signals, and the hardware interface.

7.The hub can be used as a repeater. All have the effect of amplifying the signal. Switches also have the effect of amplifying signals. But upstairs says that repeaters are switches, which is not true.

9.The key is to identify that the IP address is a Class C address, that is, the first three bytes are the network number, and the last byte is the host number, that is, all 0

11.As in question 9, the key is to identify that the IP address is Class C.

1 Choose the second 2 The sound quality also depends on the front-end 3 Because the graphics are vector data Images are scalar data 4 I haven't heard of the first one at all Maybe I'm lonely Maybe it's different on the physical level 7 The hub has long since disappeared The repeater is the switch 10 Now many viruses are memory viruses Resident memory After deletion, the virus file will be re-established.

11 is in the same network segment.

My analysis: 1, it may be that the default gateway of your router is set, but your router is not very good, and after a long time, there will be a crash, in this case, we need to restart the router, and then you can go online; 2. Whether your router is set up with the network binding function, you must have the physical MAC address and IP address of your Internet computer and input it into the router, that is, to establish a corresponding relationship, which is the so-called network control. I'm still thinking about the rest, I hope it can help you, thank you!

94 Question C is wrong, that is not the representation of the character in the computer.

Please be sure to take mine, I can assure you that I'm right.

<> only remember so much. Hope it works for you, these answers are correct.

Question 1, the effective range of the order is -10000 +1111, and the absolute range of the mantissa part is , therefore:

The maximum positive number that can be represented is, i.e., decimal;

The smallest positive number that can be represented is, i.e., decimal.

The largest negative absolute value that can be represented is decimal.

Question 2, = . The latter question is wrong, what else does hexadecimal transfer to hexadecimal......
