Computers do process all data as bits, but they prefer to process bits in byte-sized groupings. Or to put it another way: a byte is how much a computer likes to "bite" at once.

How can my laptop hold so much information? Learn how computers store information digitally by using the binary number system. You’ll also be able to explain how computers convert analog …

Any given computer will be consistent in its units, so you can compare relative file sizes, even if you're not sure the exact conversion from kilobytes to bytes.

When a computer program is reading a UTF-8 text file, it knows how many bytes represent the next character based on how many 1 bits it finds at the beginning of the byte.

Check your understanding of bytes (groupings of 8 bits) in this set of free practice questions designed for AP Computer Science Principles students.

Explore the basics of binary numbers and bits in digital information with Khan Academy's comprehensive lessons.

Computers use bits (binary digits) to represent data as ones and zeroes. Bits are the smallest piece of information a computer can store. Explore how computers use the binary number …

Packet format When sending packets using UDP over IP, the data portion of each IP packet is formatted as a UDP segment. Each UDP segment contains an 8-byte header and variable …

Bitwise simply means that we are dealing with individual bits, or binary numbers. In any modern/computerized encryption scheme we represent our symbols using binary digits.
