  Fetures of CPU Here are the key features of a Central Processing Unit (CPU):*Physical Features:*1. *Clock Speed*: Measured in GHz (Gigahertz), it determines how fast the CPU executes instructions.2. *Number of Cores*: Multiple cores allow for simultaneous processing of multiple tasks.3. *Threads per Core*: Hyper-Threading (Intel) or Multi-Threading (AMD) enables multiple threads to run on each core.4. *Cache Memory*: Small, fast memory for storing frequently accessed data.5. *Package Size*: Physical size of the CPU, affecting compatibility with motherboards.*Architectural Features:*1. *Instruction Set Architecture (ISA)*: Defines the set of instructions the CPU understands.2. *Microarchitecture*: Organization of CPU components, influencing performance and power consumption.3. *Pipelining*: Breaking down instructions into stages for faster execution.4. *Out-of-Order Execution (OoOE)*: Executing instructions out of their original order for improved performance.5. *Simultaneous Multithreading (SMT)*: Allowing multiple threads to share resources.*Performance Features:*1. *Processing Power*: Measured in MIPS (Millions of Instructions Per Second) or FLOPS (Floating-Point Operations Per Second).2. *Turbo Boost*: Dynamic clock speed increase for demanding tasks.3. *Hyper-Threading*: Enables multiple threads to run concurrently.4. *Multimedia Extensions*: Specialized instructions for graphics, video, and audio processing.5. *Power Management*: Features like idle states, frequency scaling, and voltage regulation.*Security Features:*1. *Encryption*: Integrated encryption engines for secure data processing.2. *Secure Boot*: Ensures only authorized firmware
