### What is a hexdecimal system?

That is "hexadecimal". The decimal system we often used is based on powers of 10 (each place-value is worth 10 times as much as the one to the right); the hexadecimal system is based on powers of 16, and therefore needs 16 different digits. The "digits" commonly used are the digits 0-9, the "A" for 10, "B" for 11, ... "F" for 15. This is commonly used in computers, as a sort of shorthand for…

### What does the decimal 0.75 mean?

It means seven tenths plus five hundredths. It means that the number is less than 1 but greater than zero and that it can be written as a proper fraction as 3/4. As a percentage it equates to 75%. The Western numbering system is called the decimal system and is based on multiples of powers of 10. This number means (0 * 100) + (7 * 10-1) + (5 * 10-2) = 0 + 0.7…

### What is the relation between that a kilo byte1024 bytes?

Simply it is down to mathematical powers of 2. Computer memory is based on the binary system, which is a base 2 number system. If you keep doubling 2 you get the following numbers. 2 4 8 16 32 64 128 256 1024. All of these numbers occur regularly in computers, as do numbers after those if you keep doubling up. For example there are 8 bits in a byte; there was a computer called…

### Describe how the binary number system uses only 1s and 0s to represent numbers?

The system we use is the decimal system which uses number 0 to 9 to represent numbers as big as we want. If you break a large number down in to digits, each digit represents a multiple of a power of 10. So the number 354 is: 3x10^2 (300) 5x10^1 (50) 4X10^0 (4) This same principle applies to binary where the numbers 0 and 1 are used to represent different multiple of powers of 2…

### What are hindu-arabic numeral system and roman system?

The Hindu-Arabic number system is based on ten number characters, including one symbol for zero. 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. Here appeared the number and symbol zero for the first time. [The Greeks were strong on ratios and logic, but the idea of a name for nothing - for something that had no existence - was beyond them. ] The roman number system used symbols such as I, II, V…

### What are the different ways of classifying data base management system?

DBMS can be classified in the following ways, 1. Based on Data Model Relational Data Model Object Data Model Object Relational Data Model Extended Relational Data Model XML Model Hierarchical Data Model Network data Model 2. Based on Number of Users Single User System Multi-User System 3. Based on Number of Sites Centeralized systems Distributed DBMSs(DDMSs) Homogeneous DDMS Hetrogeneous DDMS

### Why are some fractions recurring and some terminating?

A fraction is terminating when the fraction, in simplest terms, has a denominator whose only prime factors are 2 and 5. This is related to the fact that our decimal system is based on the number 10 = 2 x 5. Any other prime factor in the denominator - 3, 7, 11, etc. - will be recurring. A fraction is terminating when the fraction, in simplest terms, has a denominator whose only prime factors are…

### What created the number system based on 6?

The Sumerian system was based on a root of six. It is believed that the Sumerian civilization is the most ancient and their system of counting the very first. The Sumerian system can still be seen in our use of the foot (12 inches = 2 x 6) and yard (36 inches = 6 x 6) and in our sexagesimal measurement of time (60 seconds, 60 minuets, 24 hours = 4 x 6).

### Why cant 10 to the power of 50 3 be a square number?

10 = 2*5 (prime decomposition) So for a power of 10 to be a square means that the powers its factors must be even. A power of 10 is a square if it contains an even number of factors of 2 and 5. Since 503 is an odd number, 10^503 has an odd number of powers of 2 and 5, so it can't be the square of an integer.
