The __________ interprets the instructions in memory and causes them to be executed.

The CPU (Central Processing Unit) interprets the instructions in memory and causes them to be executed. It is often referred to as the brain of the computer because it performs the fundamental operations of a computer by executing the sequences of instructions that comprise programs. The CPU carries out tasks through a process known as the fetch-decode-execute cycle.

1. Fetch: The CPU retrieves an instruction from the memory.
2. Decode: The instruction is then decoded to determine what action is required.
3. Execute: Finally, the CPU executes the instruction, which may involve performing arithmetic operations, accessing data from memory, or controlling external devices.

By continuously cycling through these phases, the CPU manages all the processes that occur on the computer, allowing users to run applications and perform tasks seamlessly. This ability to interpret and execute instructions is fundamental to the operation of any computer system.
