Bit I/O Device 64 The memory on the serial interface must be normal for the information to be accessed when the supply voltage is normal.

Saved both in external memory and in memory.

Both external memory and memory are made up of semiconductor devices.

The following is too difficult to give you so many answers. Let's go ahead with the people below.

Transmission speed = frequency * bit width 8 (divided by 8 is to bit the unit into byte b).

In this question, it is 33*64 8=264

Select d attached: frequency is the number of packets sent per second bit width is the number of bits of data sent at one time (divided by 8 and the size of the data sent at one time, in b units). That's easier to understand, right?

1. The database can only store bytes of binary bits, not directly store various **forms, you see** such as *** rmvb and other formats how many m is that he contains millions of bytes, so 1 is wrong.

2. The fault is that IE is not an Internet service, but a software developed by Microsoft based on the Internet's HTTP, FTP, and other service protocols, which is only convenient for users to control their man-machine control, and the rest are the functions provided by the Internet.

3. The concept of the conference system may be biased in your understanding, he is not a person who says it on the **, and the rest of the people are just listening below, this information is interactively conveyed, tired to chat with QQ, so it should not be a centralized management system.

If you have any questions, you are welcome.

In question 2, A is wrong, IE belongs to software, and it is not a service provided.

1.It's binary data.

Non-centralized.

Will it be a complement?

The complement of a positive number is equal to its original value, and the complement of a negative number is equal to the end of each digit of its absolute value, ending with +1

There is a very simple way to find the complement of negative numbers, e.g. [-10101100] complement = 1,01010100

The rule is to ignore the sign bit first, look from right to left, the first 1 is unchanged, and the rest of you are negated by bit, and then write the sign bit 1 in front of it, separated by a comma.

x 2] complement means to move the complement decimal point of x to the right by one place, e.g. for a question.

x] complement=, then [x 2] complement=, x is positive before x, and after the shift, the sign bit is 1, which becomes negative, resulting in an overflow.

In the same way, [y] complement=, [-y] complement=, then [2y] complement=, [-2y] complement=, also produces overflow.

x-y] complement = [x] complement + [-y] complement =, a positive number minus a negative number becomes a negative number, and the same overflow is generated.

x] shift = , [y] shift =
