Computer Architecture Verified -

The earliest computers, like the ENIAC, were massive, room-sized machines. They were not "stored-program" computers in the modern sense; they had to be physically rewired to change their function. The architecture was rigid and strictly hardware-controlled.

David Patterson and Carlo Sequin at UC Berkeley championed Reduced Instruction Set Computing (RISC). The philosophy: make instructions simple, uniform, and execute them in one clock cycle. The result? ARM (Acorn RISC Machine) and MIPS. Computer Architecture

Often called the "brains" of the computer, it contains the Arithmetic and Logic Unit (ALU), registers (high-speed internal memory), and the Control Unit (CU) which manages instructions. Memory Hierarchy: The earliest computers, like the ENIAC, were massive,

Understanding where we are going requires knowing where we came from. The evolution of Computer Architecture is a tale of relentless miniaturization and increasing abstraction. David Patterson and Carlo Sequin at UC Berkeley
