At the most fundamental level, computers do not "know" math or language; they manipulate electrical voltages. These voltages are abstracted into binary values: and 1 (High) .

The ISA is the abstract boundary between hardware and software. It defines the commands a processor can natively understand. Common types include:

Rewrites parts of the code to make it run faster or consume less memory without changing its output. logic gates circuits processors compilers and computers pdf

Modern integrated circuits use CMOS technology, which pairs two types of transistors:

A Central Processing Unit (CPU) is an intricate network of millions or billions of transistors acting as logic gates. It operates based on a "clock speed" (measured in Hz), which dictates how quickly it can execute instructions. At the most fundamental level, computers do not

| Input A | Input B | Output (A XOR B) | | :---: | :---: | :---: | | 0 | 0 | 0 | | 0 | 1 | 1 | | 1 | 0 | 1 | | 1 | 1 | 0 |

A computer system consists of several key components:

The foundational elements of calculation. A Half Adder adds two single binary digits and outputs a Sum and a Carry . A Full Adder accepts three inputs (including a Carry-in from a previous stage), allowing computers to chain them together to add massive numbers.

possible options. They are essential for memory addressing and instruction decoding. Sequential Logic Circuits

Circuits that store a single bit of data, forming the basis of computer memory (RAM). 2. The Brain: Processors (CPUs)
