One hexadecimal digit can be converted to how many binary bits?
8
How many binary bits are necessary to represent 748 different numbers?
Binary bits are necessary to represent 748 different numbers in the sense that binary bits are represented in digital wave form. Binary bits also have an exponent of one.
How many different values can be represented by 4 binary digits?
24, or 16 (0 through 15) One binary digit (bit) can have 21 values (0 or 1). Two bits can have 22 values. Three bits can have 23 values. A five-bit number can have 25 values... and so on...
What is the decimal conversion of the binary number 1010?
10. From right to left, each digit is double the previous one, like this: 8, 4, 2, 1.
What is the unit of measurement used with computer system?
There are a variety of units used to measure computer systems. One is the bit, which is essentially a 1 digit binary number. This can be used to describe the "bit width" or how large a number your computer can handle at once. An 8 bit computer can handle up to an 8 digit binary number, equivalent to 256. Another unit is the hertz, which is the number of times your computer can do one command in a second. A 3 GHz computer can do 3 billion commands in 1 second. There are many other less used units but those 2 are the most common. Note that these are not measurements of the "computer system". One is a measurement of information quantity, the other is a measurement of the frequency of electrical events. Similarly, a few other units associated with "computer system" measurements are the inch, the pound, and the dollar. Their specific definitions and applications aren't likely to require explanation.
