Key Aspects of CPU 2.2.1 Records: CPU Usage Rate: This record monitors the percentage of time a processor is actively in use. Process-Specific CPU Usage: To identify bottlenecks caused by a specific application, you must check the CPU usage rate for individual processes using PFM-Agent for Platform. Run Queue (Process/Thread Count): This record shows the number of processes or threads waiting in the execution queue. An elevated value indicates potential issues with system operating procedures, the OS, or a specific application causing excessive processor use. Hardware Interrupts: If a CPU usage value increases significantly when system workload is light, it could signal a hardware interrupt problem, such as a slow device overloading the processor. Multiprocessor Environments: In a multiprocessor system, the CPU usage rate for the system is the average of all CPU usage rates, making it important to check each individual CPU for accurate monitoring

 CPU Structure The fundamental components of a CPU are: Control Unit (CU): Manages the CPU's activities by letting, decoding, and executing instructions, and directing the flow of data and signals to other components like the ALU and memory. Arithmetic Logic Unit (ALU): The "brain" of the CPU, responsible for performing all mathematical calculations (addition, subtraction, etc.) and logical operations (comparisons, AND, OR, etc.) required by programs. Registers: Small, extremely fast internal memory locations within the CPU used to hold the data, instructions, and memory addresses that are actively being processed. Cache Memory: A small, very fast memory located adjacent to the CPU that stores frequently used data and instructions, allowing the CPU to access them more quickly than if it had to retrieve them from main memory (RAM).

 RISC (Reduced Instruction Set Computer) RISC is the way to make hardware simpler whereas CISC is the single instruction that handles multiple work. In this article, we are going to discuss RISC and CISC in detail as well as the difference between RISC and CISC. Let's proceed with RISC first. Reduced Instruction Set Architecture (RISC) The main idea behind this is to simplify hardware by using an instruction set composed of a few basic steps for loading, evaluating, and storing operations, just like a load command will load data; a store command will store the data. Characteristics of RISC Simpler instruction, hence simple instruction decoding. Instruction comes undersize of one word. Instruction takes a single clock cycle to get executed. More general-purpose registers. Simple Addressing Modes. Fewer Data Types. A pipeline can be achieved.

Architectures Von Neumann  Caracteristicas: 1.- stored-program computers 2.- bottleneck= Cuello de botella Harvard Architecture 1.- Allowing simultaneous access 2.- Concurrent access

 To test a hypothesis that big old sparks can kill a PC. or they'll overclock it. So every time we build a PC, saying that we should be wearing static wristbans to protect the components. Safely grounded and can build a PC without endangering components, health, or safety.  Static shock showdown.  We might have killed it, not just the video card,

 Important parts inside a computer but what exactly do let's take a look inside and learn about the various components that make a computer work whether it¡s desktop computer or a laptop every computer has a large circuit board called a motherboard this contains some of the most important parts of the computer such as the   CPU also known as the central processing unit or processor the CPU can be considered the brain of the computer because it processes information and carries out commands since tends to get hot it's covered by a piece of metal called a heat sink which draws heat away from the processor the motherboard also contains the computer's. RAM = random Access Memory short-term memorycan't store files cleared when you turn off computer
