Hardware architecture
- [Instructor] You might already know that a central processing unit, or CPU, lies at the heart of every computer system. The CPU is responsible for executing all of the instructions that software gives to a computer. It contains the hardware that carries out all of those tasks. Different CPUs work in different ways, and we can describe the types of instructions and hardware supported by a particular family of CPUs as the hardware architecture. Most of the computers that we use today use a hardware architecture called x86. That's an instruction set that comes from the early days of Windows systems, and it's the major instruction set used on modern computers in processors made by Intel and AMD. The ARM architecture is another common architecture in use today. It was originally used mainly on mobile devices, but now is also commonly found in chips made by Apple for use in Mac systems using the M1 and M2 processors. The most…
