The number of samples stored per second. Measured in Hertz

A style of compression that can compress data files without losing any of the information. Adv - reversible so that the original data can be reconstructed.  Dadv - unsuitable for tect files / programs, 

What is lossless compression? Adv / Aadv?

Compresses data files by getting rid of some of the information. Adv - compresses files greatly, suitable for media files  Dadv - cannot be decompressed

Including the necessary details and getting rid of unnecessary details

Breaking down one complex problem into smaller, more manageable sub-problems

Errors that produce enexpected outputs but don't stop the program from running

When the result of an addition is too large for the number of bits the computer had the capacity for

Control Unit, Arithmetic Logic Unit, Main Memory, Inputs and Outputs

What does von Neumann architecture consist of?

Left - shifts value one digit to the left (multiplies by 2)           Right - shifts value one unit to the right (divides by 2)

What does a binary shift left / right do?

Smallest unit of storage, a single binary digit that can only be represented with a 1 (true) or a 0 (false)

Performs arithmetic calculations and makes logical decisions

Sends signals to control how data moves around the CPU

Temporary storage of data and instructions being read from and written to memory located in the CPU

A register in the CPU that holds the address of the next instruction to be executed in memory

Holds data and instructions that the CPU needs to access while the computer is running (RAM, ROM, caches)

Storing running programs in secondary storage when main memory becomes full to allow the computer to continue to run

A register in the CPU that holds the results of calculations

A register in the CPU that holds the memory adress where data is to be fetched from or written to
