What is CPU and it's components

-
      CPU :-  C.P.U is the brain of the computer.

  
   It's components is :
  • It is called processor.
  • It can be placed on one or more microchip called integrated circuit (IC).
  • IC is semiconductor material.
 WORK OF THE C.P.U :
  •  The C.P.U is given instructions and data through programs, then C.P.U fetches program and data from the memory and performs arithmetic and logic operation as per the given instructions and store back to memory.

  •   While processing, the C.P.U stores the data as well as instructions in local memory called registers. 
      
  • Register are used for storing data, instructions or   intermediate results. 
   
 Other than register, C.P.U has two main components:-
  • ALU  (Arithmetic logic unit)
  • CU  (Control unit) 

  • ALU (arithmetic logic unit)  performs all the arithmetic and logic operation that need to be done as per the instruction in a program.
  • CU (control unit)  controls sequential instruction execution, interprets instructions and guides data flow through the computer's  memory, ALU and input or output device.
            WORKING PROCESS
INPUT  DEVICE :- Convert input data into a digital form that is acceptable by the computer system.
 
OUTPUT  DEVICE :- Convert digital information into human understable form.

  Understanding How Hydraulics Work Hydraulics is a branch of engineering and physics that uses the mechanical properties of fluids, typically liquids, to perform work. From heavy machinery like excavators to car brakes, hydraulics is the driving force behind numerous industrial, automotive, and everyday systems. The principle that governs hydraulics is simple yet powerful: liquids are incompressible and can transmit force efficiently in a confined space. In this essay, we will delve into the fundamental principles, components, and applications of hydraulics, highlighting the science behind their operation and their significance in modern engineering. Fundamental Principles of Hydraulics The operation of hydraulics is based on two fundamental concepts: Pascal's Law and the properties of fluids. 1. Pascal's Law Discovered by Blaise Pascal, this law states that pressure exerted on a confined fluid is transmitted undiminished in all directions throughout the fluid . This principle...

How does Refrigerator cool?

A refrigerator operates on the principles of thermodynamics, utilizing a combination of components and processes to maintain a cool temperature inside. The fundamental concept behind refrigeration is the removal of heat from the interior of the refrigerator, thus lowering the temperature and preserving the contents. Let's delve into the intricate workings of a refrigerator, exploring its key components and the science behind its cooling mechanism. 1. Refrigeration Cycle: It the heart of every refrigerator is the refrigeration cycle, a continuous process that involves the circulation of a refrigerant through various components. The cycle begins with the compression of the refrigerant, typically a gas, in the compressor unit of the refrigerator. 2. Compressor: The compressor plays a pivotal role in the refrigeration cycle. It pressurizes the low-pressure, low-temperature gas refrigerant, causing it to become a high-pressure, high-temperature gas. T...

  HTML Overview HTML ( HyperText Markup Language ) is the standard language used to create webpages. It structures the content by defining elements like text, images, links, and forms. HTML is made up of tags , which are enclosed in angle brackets ( < . > ) Most tags come in pairs: an opening tag ( <tag> ) and a closing tag ( </tag> ) , with content placed between the two. Some tags, however, are self-closing. Basic Structure of an HTML Document html < !DOCTYPE html > < html lang = "en" > < head > < meta charset = "UTF-8" > < meta name = "viewport" content = "width=device-width, initial-scale=1.0" > < title > Document Title </ title > </ head > < body > < h1 > Hello, World! </ h1 > < p > This is a paragraph. </ p > </ body > </ html > <!DOCTYPE html> : Declares the document type and versi...
