Question 2. What is a 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 bit value of 0;

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

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

Question 3. To measure the use of large volumes of information units such as kilobytes, megabytes, gigabytes. What is the kilobyte?

1. 1 Kilobyte = 1000 bytes, or 103 bytes;

2. 1 Kilobyte = 1,000,000 bytes, or 106 bytes;

3. 1 Kilobyte = 1,000,000,000 bytes, and 109 bytes;

4. 1 Kilobyte = 1024 bytes, or 210 bytes;

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

Question 4: What is the difference from one another decimal, binary, octal and hexadecimal number system?

1. Based on these number systems are respectively numbers 10, 2, 8, 16 used the numbers from 0 to 9 When writing numbers in the decimal system; in binary number written in any form of a sequence of 0 and 1; octal numbers are used to record the numbers from 0 to 7; hexadecimal number, you can record with 16 characters - digits from 0 to 9 and Latin letters from A to F;

2. The grounds of the number systems are respectively numbers 10, 2, 8, 16. When writing numbers in the decimal system uses numbers from 0 to 10; in binary number written in any form of a sequence of 0 and 1; octal numbers are used to record the numbers from 0 to 8; hexadecimal number, you can record the numbers from 0 to 16.

3. Based on these number systems are respectively numbers 10, 2, 8, 16.
