HOW DOES A SOUND CARD AND VIDEO CARD WORK

  HOW DOES A SOUND CARD AND VIDEO CARD WORK? A SOUND CARD, ALSO KNOWN AS AN AUDIO INTERFACE OR AUDIO CARD, IS A HARDWARE COMPONENT IN A COMPUTER THAT IS RESPONSIBLE FOR PROCESSING AND MANAGING AUDIO SIGNALS. ITS PRIMARY FUNCTION IS TO CONVERT DIGITAL DATA INTO ANALOG SIGNALS THAT CAN BE PLAYED THROUGH SPEAKERS OR HEADPHONES, AND VICE VERSA. HERE'S A BRIEF OVERVIEW OF HOW A SOUND CARD WORKS IN A PC: 1.     INPUT AND OUTPUT: ·          INPUT: WHEN YOU SPEAK INTO A MICROPHONE OR CONNECT ANOTHER AUDIO SOURCE TO YOUR COMPUTER, THE SOUND CARD CONVERTS THE ANALOG AUDIO SIGNALS FROM THE MICROPHONE INTO DIGITAL DATA THAT THE COMPUTER CAN PROCESS. ·          OUTPUT: WHEN YOU PLAY MUSIC, VIDEOS, OR ANY OTHER AUDIO CONTENT ON YOUR COMPUTER, THE SOUND CARD CONVERTS THE DIGITAL AUDIO DATA INTO ANALOG SIGNALS THAT CAN BE SENT TO SPEAKERS OR HEADPHONES FOR YOU TO HEAR. 2.  ...

IT ACTS AS A BRIDGE BETWEEN THE CENTRAL PROCESSING UNIT (CPU) AND THE STORAGE DEVICES, ENSURING SMOOTH DATA PROCESSING AND RETRIEVAL. WITHOUT MEMORY, A COMPUTER CANNOT PERFORM ANY OPERATION. COMPUTER MEMORY IS BROADLY CATEGORIZED BASED ON ACCESS TIME, CAPACITY, COST, AND VOLATILITY . IT DETERMINES THE PERFORMANCE AND EFFICIENCY OF THE ENTIRE SYSTEM. TYPES OF COMPUTER MEMORY COMPUTER MEMORY IS MAINLY DIVIDED INTO PRIMARY MEMORY AND SECONDARY MEMORY , AND ALSO INCLUDES CACHE MEMORY AND VIRTUAL MEMORY AS SPECIAL TYPES. 1. PRIMARY MEMORY (MAIN MEMORY) PRIMARY MEMORY IS DIRECTLY ACCESSIBLE BY THE CPU. IT IS FAST BUT LIMITED IN SIZE AND VOLATILE IN NATURE, MEANING DATA IS LOST WHEN POWER IS TURNED OFF.

FLASH MEMORY - A SHORTNOTE

 FLASH MEMORY HELLO FRIENDS TODAY I AM GOING TO TELL YOU  SOMETHING ABOUT WHAT  I KNOW ABOUT A TOPIC KNOWN AS  VIRTUAL MEMORY, SO LETS BEGIN. VIRTUAL MEMORY IS A MEMORY MANAGEMENT CAPABILITY OF AN OPERAING SYSTEM THAT USES HARDWARE AND SOFTWARE TO ALLOW A COMPUTER TO COMPENSATE FOR PHYSICAL MEMORY SHORTAGES BY TEMPORARILY TRANSFERING DATA FROM RAM TO INACTIVE SPACE IN HARD DISK DRIVES TO FORM CONTIGOUS ADDRESESE THAT HOLD BOTH THE APPLICATION AND ITS DATA. A SYSTEM USING VIRTUAL MEMORY USES A SECTION OF HARD DISK DRIVE TO EMULATE RAM WITH VIRTUAL MEMORY A SYSTEM CAN LOAD LARGER PROGRAMS LIKE PUBG OR FREE FIRE RUNNING AT THE SAME TIME ALLOWING NO MORE RAM REQUISITE. WHILE COPYING VIRTUAL MEMORY INTO THE PHYSICAL MEMORY THE OS DIVIDES MEMORY INTO PAGE FILES WITH A FIXED NUMBER OF ADDRESSES. EACH PAGE IS STORE ON A DISK AND WHEN THE PAGE IS NEEDED THE OS COPIES IT FROM THE DISK TO THE RAM.  THIS IS CALLED A PAGE SWAPPING. SO LETS SEE HOW TO CONFIGURE A VIRTUAL MEMO...
