Conversions and Binary Flashcards
1 bit
1 letter, number, or symbol
8 bits equals ___.
1 byte
1,024 bytes equals ___.
1 kilobyte (KB)
1,024 kilobytes (KB) equals __.
1 megabyte (MB).
1,024 megabytes equals ___.
1 gigabyte (GB).
1,024 gigabytes equals ____.
1 terabyte (TB)
What is the order of bytes from “byte” to “terabyte”?
byte, kilobyte, megabyte, gigabyte, terabyte
Smallest to largest by 1,024.
What is binary?
The communication that a computer uses.
Also known as a base 2 numerical system.
Binary has binary data, called “bits”, which are combinations of 1 and 0.
The 1’s are considered “on” and the 0’s are considered “off”.
We group 8 bits together to equal a byte.
How many possible values can we have with 8 bits?
256.
Bits use the binary system, which is the base 2 numerical system.
UTF-8 replaced the ASCII because ___.
The UTF-8 can store a character in more than a single byte.
This allows us to represent a lot more character types, like emoji. UTF-8 is now the unicode standard.
The highest decimal value we can represent with a byte is ___.
- There are 256 values in a byte, from the decimal number 0 to 255.
What are logic gates?
They are allow transistors to do more complex tasks like deciding where to send electrical signals. They deal with boolean logic (true or false-type) and choosing where to send signals based on that.
What is a transistor?
Transistors are the primary building blocks of all microchips and CPU for the motherboard. They create the binary 1’s and 0’s for the computer, so it can communicate with logic gates and send data different places.
