INTRODUCTION
THE SYSTEM UNIT, ALSO KNOWN AS A "TOWER' OR "CHASSIS" , CONTAINS THE MAIN COMPONENTS OF A DESKTOP COMPUTER. THE SYSTEM UNITVIS A CASE THAT CONTAINS ELECTRONIC COMPONENTS OF THE COMPUTER USED TO PROCESS DATA. IT INCLUDES THE MOTHERBOARD, CPU, RAM, AND OTHER COMPONENTS.

SYSTEM UNIT CASE
A SYSTEM UNIT CASE, ALSO KNOWN AS A PC CASE, IS ESSENTIAL FOR HOUSING AND PROTECTING YOU COMPUTER COMPONENTS. ALSO KNOWN AS A COMPUTER CHASSIS, IS THE ENCLOSURE THAT CONTAINS MOST OF THE HARDWARE OF A PERSONAL COMPUTER.
POWER SUPPLY UNIT
IS THE COMPONENTS THAT CONVERTS HOUSEHOLD ELECTRICITY INTO THE APPROPRIATE VOLTAGE AND CURRENT REQUIRED BY OTHER COMPONENTS INSIDE THE COMPUTER.
MOTHERBOARD
IT IS OFTEN CALLED THE 'MAINBOARD", IS THE CENTRAL CIRCUIT BOARD WITNIN A COMPUTER. IT CONNECTS ALL OF THE INTERNAL COMPONENTS, LIKE THE MEMORY, PROCESSOR, GRAPHICS CARD AND OTHER HARDWARE. IT ALSO PROVIDES POWER TO EACH COMPONENT AND ALLOWS THEM TO COMMUNICATE WITH EACH OTHER.
CENTRAL PROCESSING UNIT (CPU)
CPU IS OFTEN REFERRED TO AS THE "BRAIN" OF THE COMPUTER, IS RESPONSIBLE FOR EXECUTING INTRUCTIONS AND PERFORMING CALCULATIONS. IT IS RESPONSIBLE FOR CARRYING OUT THE INSTRUCTIONS FROM SOFTWARE, INCLUDING THE OPERATING SYSTEM, APPLICATIONS, AND USER PROGRAMS.
RANDOM-ACCESS MEMORY (RAM)
IS A FORM OF ELECTRONIC COMPUTER MEMORY THAT CAN BE READ AND CHANGED IN ANY OTHER, TYPICALLY USED TO STORE WORKING DATA AND MACHINE CODE.
HARD DISK DRIVE (HDD)
IS THE HARDWARE COMPONENTS THAT STORES ALL YOUR DIGITAL CONTENT. YOUR DOCUMENTS, PICTURES, MUSIC, VIDEOS, PROGRAMS, APPLICATION PREFERENCES, AND OPERATING SYSTEM REPRESENT DIGITAL CONTENT STORED ON A HARD DRIVE. IT IS A DATA STORAGE DEVICE THAT USES RAPIDLY ROTATING MAGNETIC PLATTERS TO STORE AND RETRIEVE DIGITAL DATA, FUNCTIONING AS AS PRIMARY STORAGE MEDIUM FOR OPERATING SYSTEMS SOFTWARE, AND USER FILES.
AUDIO/SOUND CARD
A SOUND CARD IS AN INTERNAL EXPANSION CARD THAT PROVIDES INPUT AND OUTPUT OF AUDIO SIGNALS TO AND FROM COMPUTER UNDER THE CONTROL OF COMPUTER PROGRAMS. THE TERM SOUND CARD IS ALSO APPLIED TO EXTERNAL AUDIO INTERFACES USED FOR PROFESSIONAL AUDIO APPLICATIONS.
CHASSIS FAN
IT HELPS TO KEEP THE INSIDE OF A COMPUTER COOLBY CIRCULATING AIR. THE PREVENTS OVERHEATING OF COMPONENTS LIKE THE CPU, GPU, AND MOTHERBOARD, WHICH CAN LEAD TO PERFORMANCE ISSUES OR EVEN DAMAGE.
LAN CARD
A LAN CARD ALLOWS YOUR COMPUTER TO CONNECT TO A LOCAL ARE NETWORK (LAN). THIS ENABLES YOU TO SHARES FILE, PRINTER, AND OTHER RESOURCES WITH OTHER DEVICES ON THE SAME NETWORK, AND TO ACCESS THE INTERNENT THROUGH A ROUTER.
CPU HEAT SINK
IS A COMPONENT ATTACHED TO THE TOP OF THE CPU, DESIGNED TO DRAW AWAY HEAT GENERATED BY THE PROCESSOR. IT IS DESIGNED TO ABSORB THE HEAT COMING FROM YOUR CPY THE DISPERSE THE HEAT AWAY FROM ITS COMPONENTS. THE DISSIPLATION OF HEAT IS POSSIBLE BECAUSE A HEAT SINK HAS FINS, WHICH GIVES MORE SURFACE AREA DURING A HEAT TRANSFER. A HEAT SINK NEEDS TO MAKE STRONG CONTACT WITH THE SOURCE OF HEAT IN ORDER TO MAXIMIZE COOLING.
CD/DVD ROM
IS AN OPTICAL DISC DRIVE USED IN COMPUTERS TO READ DATA FROM CDs AND DVDs. THESE DISCS STORES DIGITAL DATA SUCH AS SOFTWARE, MUSIC, MOVIES, AND GAMES.
CMOS BATTERY
A CMOS (COMPLEMENTARY METAL OXIDE SEMICONDUCTOR) BATTERY, ALSO CALLED COIN-CELL BATTERY ON THE MOTHERBOARD HELPS THE BIOS OR UEFI TO STORE THE HARDWARE CONFIGURATION SETTINGS. IT HELPS KEEP A RECORD OF THE DATE AND TIME WHEN THE COMPUTER IS SWITCHED OFF.
FLOPPY DISK
A FLOPPY DISK IS A MAGNETIC STORAGE MEDIUM FOR COMPUTER SYSTEMS. THE FLOPPY DISK IS COMPOSED OF A THIN, FLEXIBLE MAGNETIC DISK SEALED IN A SQUARE PLASTIC CARRIER. IN ORDER TO READ AND WRITE DATA FROM A FLOPPY DISK A COMPUTER SYSTEM MUST HAVE A FLOPPY DISK DRIVE.
CPU FAN
A COMPUTER FAN IS ANY FAN INSIDE, OR ATTACHED TO, A COMPUTER CASE USED FOR ACTIVE COOLING. FANS ARE USED TO DRAW COOLER AIR INTO THE CASE FROM THE OUTSIDE, EXPEL WARM AIR FROM INSIDE AND MOVE ACROSS A HEAT SINK TO COOL A PARTICULAR COMPONENT.
SATA WIRE
AN INDUSTRY-STANDARD BUS INTERFACE FOR CONNECTING A COMPUTER'S HOST BUS ADAPTER TO STORAGE DEVICES SUCH AS HARD DISK DRIVES (HDD), OPTICAL DRIVES AND SOLID-STATE DRIVES (SSD). SERIAL ATA (SATA) CABLE.
PATA WIRE
THE FULL FORM OF PATA IS PARALLEL ADVANCED TECHNOLOGY ATTACHEMT. PATA IS AN INTERFACE STANDARD USED TO CONNECT SECONDARY STORAGE DEVICES LIKE FLOPPY DISK DRIVES, HARD DISK, OPTIC DISC DRIVES TO OLDER COMPUTER. IT IS ONE OF THE CABLE COMPONENTS USED IN A MOTHERBOARD, AND ITS PRIMARY FUNCTION IS TO TRANSFER DATA.
