The bit depth reflects the number of binary numbers available, similar to the number of combinations available on a padlock. The more wheels of numbers on a padlock, the more combinations of numbers are possible. The greater the bit depth, the more combinations of binary numbers are possible. Every time the bit depth increases by one, the number of binary combinations is doubled. Asked 11 years, 1 month ago. Active 2 years, 5 months ago.

Why it closed : It is not related to "specific moment in time" If you have 8 octal combination for five places then total possible combinations will be 8 pow 5. Add a comment. Active Oldest Votes. Their range will depend on the system you are using: Unsigned: 0 to 2 k -1 Signed: -2 k-1 to 2 k-1 Improve this answer. You raise a very interesting point. I hadn't thought of signed and unsigned integers.
What you're missing: Zero is a value. SamStephens SamStephens 5, 6 6 gold badges 33 33 silver badges 44 44 bronze badges. A better way to solve it is to start small. Randy the Dev Randy the Dev By the way, an good followup exercise would be to generalize this: How many different values can be represented in n binary digits bits? The abbreviations for numbers of bits use a lower-case "b" instead of an upper-case "B". Since one byte is made up of eight bits, this difference can be significant.
For example, if a broadband Internet connection is advertised with a download speed of 3. Bits and bit rates bits over time, as in bits per second [bps] are most commonly used to describe connection speeds, so pay particular attention when comparing Internet connection providers and services.

A computer stores information in Binary format. Binary is a number system which uses BITS to store data. BITS A bit is the smallest element of information used by a computer.
Because a single bit can only store two values, bits are combined together into large units in order to hold a greater range of values.
This gives a maximum number of 16 possible different values. It is useful, when dealing with groups of bits, to determine which bit of the group has the least value, and which bit has the most or greatest value. The Most significant bit is always shown on the extreme left, and is the bit with the greatest value. They can also be used to store numeric values,. The valid combinations of bits and their respective values are. The unused nibble may be either all 0's or all 1's.
This occurs in data transmission where numbers are being transmitted over a communications link. Packed BCD reduces the amount of time spent transmitting the numbers, as each data byte transmitted results in the sending of two BCD digits. The computer handles each boolean variable as a single bit. If the bit is TRUE, then is has a value of 1.
