## Product description

Test "Informatics" - 34 tasks on 5 questions (IMEI)

1. Foundations of Computer Science

Task 1

Question 1. In what form the information received PC (personal computer)?

1 in the form of digital signals (digital computer);

2 in the form of continuous signals (analog computer);

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?

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

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

4. Based on these number systems are, respectively, the number of 10, 2, 8, 16. When writing numbers in the decimal system uses numbers from 0 to 9; in any binary number is written as 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 17. In computing is only used the decimal system.

5. Based on these number systems are, respectively, the number of 10, 2, 8, 16. When writing numbers in the decimal system uses numbers from 0 to 9; in any binary number is written as 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.

Question 5. Decimal 30 is written in binary as:

1. 10011;

2. 11110;

3. 10101;

4. 100111;

5. 100001.

Task 2

Question 1: The basic unit of measurement of the amount of information - it is:

1. Byte;

2 Kbytes;

3. MB;

4. Bit;

5. The eight bits.

Question 2. Given the number system: base 2, 8, 10, 16. Record type 100

1. Binary offline;

2. There is in all of these;

3. there is no decimal;

4. offline octal;

5. absent in 16-tion.
