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.  ...

BRIGHTNESS LIGHTNESS LUMINOSITY LUMINANCE   -THESE TERMS REFER TO DARK TO LIGHT TONAL CHARACTERISTICS, AS OPPOSED TO COLOR CHARACTERISTICS.  THEY CAN BE THOUGHT OF AS DESCRIBING THE IMAGE AS IF THE COLORS HAD BEEN CONVERTED TO BLACKS GRAYS AND WHITES

 

HUE – IT IS IDENTIFIED BY THE NAME OF THE COLOR SUCH AS RED ORANGE AND GREEN.  THE LIGHTNESS OR THE DARKNESS OF THE COLOR IS THOUGHT OF SEPARATE FROM THE HUE.  HUE CAN BE MEASURED ON LOCATION ON THE STANDARD COLOR WHEEL AND EXPRESSED A DEGREE AS BETWEEN 0 DEGREE TO 360 DEGREE.

JOYSTICK WORKING AND DRIFT :GAMING TO AEROSPACE

  TITLE: THE EVOLUTION AND MECHANICS OF JOYSTICKS: FROM GAMING TO AEROSPACE INTRODUCTION: JOYSTICKS HAVE TRANSCENDED THEIR ORIGINS AS MERE GAMING PERIPHERALS TO BECOME INTEGRAL COMPONENTS IN VARIOUS INDUSTRIES, FROM AVIATION AND SPACE EXPLORATION TO MEDICAL EQUIPMENT AND INDUSTRIAL MACHINERY. THESE VERSATILE INPUT DEVICES HAVE EVOLVED SIGNIFICANTLY SINCE THEIR INCEPTION, OFFERING PRECISE CONTROL AND ERGONOMIC DESIGN. THIS ARTICLE DELVES INTO THE EVOLUTION, MECHANICS, AND DIVERSE APPLICATIONS OF JOYSTICKS ACROSS DIFFERENT FIELDS. HISTORY OF JOYSTICKS: THE CONCEPT OF THE JOYSTICK DATES BACK TO THE EARLY 20TH CENTURY WHEN IT WAS INITIALLY USED IN AVIATION FOR CONTROLLING AIRCRAFT. THE EARLIEST JOYSTICKS WERE SIMPLE MECHANICAL DEVICES CONSISTING OF A LEVER MOUNTED ON A PIVOT, WHICH PILOTS USED TO MANEUVER THEIR PLANES. OVER TIME, JOYSTICKS FOUND THEIR WAY INTO ARCADE GAMES, HOME CONSOLES, AND EVENTUALLY PERSONAL COMPUTERS, REVOLUTIONIZING THE GAMING INDUSTRY. MECHANICS OF JOY...

CUSTOM CONFIGURATION OF A PC

  CUSTOM CONFIGURATION OF PC APART FROM BRANDED COMPLETE PC’S LIKE IMAC, HP, HCL THE USER CAN ASSEMBLE A PC ACCORDING TO HIS NEED AND USABILITY. GRAPHIC/CAD/CAM WORKSTATIONS A SURVEY REVEALED THAT 11 PERCENT OF GRAPHIC DESIGNERS AND ENGINEERS USED MOBILE WORKSTATIONS FOR CAD AND 8 PERCENT USED STANDARD PC NOTEBOOKS.   LAPTOP CONFIGURATIONS ARE NOT MADE TO GRAPHICS INTENSIVE ACRIVITIES LIKE CAD, NOR ARE THEY GFENERALLY BUILT FOR USE IN EXTREME CONDITION LIKE CONSTRUCTION SITES, OIL RIGS AND INDUSTRIAL PLANTS.   A GRAPHIC DESIGN OR CAD USABLE PC SHOULD HAVE A BETTTER PROCESSING SPEED BETTER QUALITY OF IMAGES.   THE FOLLOWING ARE THE SPECIFICATIONS TO CUSTOMIZE GRAPHIC DESIGN WORKSTATIONS.   POWERFUL PROCESSOR WHEN WE CONSIDER GRAPHIC DESIGN WORKSTATIONS, THE PROCESSOR POWER IS THE FIRST CRITERIA TO LOOK IN.   IT IS NECESSARY TO GAUGE THE PURPOSE OF THE MACHINE WHEN CHOOSING THE CPU PROFILE OF A COMPUTER.
