All ____ is represented as ____ digits, whether it is numbers, text, ____ or sound. ____ are also done in binary. In a computer, all data is stored in ____ form. A binary digit has ____ possible states, 1 and 0.A binary ____ is known as a ____. A bit is the ____ unit of data a computer can use. The binary unit system is used to describe ____ numbers too. ____ bits are known as a ____. ____ bits or ____ a byte is known as a nibble. ____ data is a real-life signal that can vary greatly in value. Examples include:- ____ waves - ____ - ____ ____ data is ____ data which represents analogue data. ____ work with digital data. Analogue data must be ____ to digital before a computer can use it. A device known as an ____ convertor (ADC) is used to generate digital data from analogue signals. In the same way, a digital signal can be converted ____ to an analogue signal using a digital-to-analogue convertor ____. ____ tend to use the ____ number system. However, computers work in ____. Denary numbers must be ____ into their binary equivalent before a ____ can use them. The ____ system has ____ digits (0, 1, 2, 3, 4, 5, 6, 7, 8 and 9). Each denary ____ value is calculated by ____ the previous place value by ten. For example:10,000 1,000 100 10 1 ____ has just two units, ____ and ____. The value of each binary place value is calculated by ____ the previous place value by ____. The first ____ binary place values are: 128 64 32 16 8 4 2 1 In ____, each place value can only be represented by ____ or a ____.To convert binary to ____, simply take each place value that has a 1, and ____ them together. Example - binary number 1111100 Result: (0 × 128) + (1 × 64) + (1 × 32) + (1 × 16) + (1 × 8) + (1 × 4) + (0 × 2) + (0 × 1) = 124 What would these binary numbers be in denary?- 1001 = ____ - 10101 = ____ - 11001100 = ____ To convert from ____ to binary, start by ____ the ____ place value you can from the denary number, then place a 1 in that place value column. Next, ____ the ____ biggest place value you can, and place a ____ in the column. Repeat this process until you reach ____. Finally, place a ____ in any empty place value columns. Example - ____ number 84First set up the columns of ____ place values. 128 64 32 16 8 4 2 1 ____ is the biggest place value that can be ____ from 84. Place a ____ in the 64 place value column and subtract 64 from 84, which gives ____. 16 is the biggest place value that can be subtracted from 20. Place a 1 in the ____ place value column and subtract 16 from 20, which gives ____. 4 is the biggest place value that can be subtracted from 4. Place a 1 in the 4 place value column and subtract 4 from 4, which gives ____. Place a 0 in each remaining ____ place value column. Result: 84 in denary is 1010100 in binary. To check that this is right, convert the ____ back to ____: (0 × 128) + (1 × 64) + (0 × 32) + (1 × 16) + (0 × 8) + (1 × 4) + (0 × 2) + (0 × 1) = 84 Another way to ____ a denary number to binary is to ____ the starting number by two. If it divides ____, the binary digit is 0. If it does not and there is a ____, the binary digit is ____. Finally, ____ the digits and you have the correct number. What would these denary numbers be in binary?- 12 = ____ - 42 = ____ - 188 = ____ When two numbers are added together in ____, we take the first number, ____ the second number to it, and get an answer. For example, 1 + 2 = ____. When we add two ____ numbers together the process is ____. There are ____ rules that need to be followed when adding two ____ numbers. These are:1) 0 + 0 = 0 2) 1 + 0 = 1 3) 1 + 1 = 10 (binary for denary ____ 4) 1 + 1 + 1 = 11 (binary for denary ____
