3 mainly in the form of digital signals, and sometimes - a continuous signal;

4 mainly in the form of continuous signals, and sometimes - in the form of discrete signals

5. there is no right answer.

Question 2. What is the bit?

1. The bit can take on any value;

2. The bit is the basic unit of information is the number of bits of value 1;

3. bit - is the basic unit of information is the number of bits of value 0;

4. bit - is the basic unit of information, bit value is an octal number 2;

5. bit - is the basic unit of information is the bit value of 0 or 1.

Question 3: In order to measure large amounts of information using such units as the kilobytes, megabytes, gigabytes. What is the KB?

1. 1 Kilobyte = 1000 bytes or 103 bytes;

2. 1 Kilobyte = 1 million bytes, or 106 bytes;

3. 1 Kilobyte = 1 billion bytes, or 109 bytes;

4 1 K = 1024 bytes or 210 bytes;

5. 1 Kilobyte = 1,048,576 bytes, or 220 bytes.

Question 4. What is different decimal, binary, octal and hexadecimal number system?
