INTERFACES IN COMPUTER AND USB IN DETAIL

IN COMPUTING, AN INTERFACE IS A SHARED BOUNDARY ACROSS WHICH TWO SEPARATE COMPONENTS OF A COMPUTER SYSTEM EXCHANGE INFORMATION. THERE ARE SEVERAL DIFFERENT TYPES OF INTERFACES, CATEGORIZED BASED ON THEIR PURPOSE AND WHERE THEY ARE USED. HERE'S A BREAKDOWN OF THE MAIN TYPES: 1. USER INTERFACES (UI) THESE ALLOW HUMANS TO INTERACT WITH COMPUTERS. GRAPHICAL USER INTERFACE (GUI): USES WINDOWS, ICONS, MENUS, AND POINTERS (E.G., WINDOWS, MACOS, GNOME). COMMAND-LINE INTERFACE (CLI): USERS TYPE COMMANDS INTO A CONSOLE OR TERMINAL (E.G., LINUX TERMINAL, COMMAND PROMPT). TOUCH USER INTERFACE: USES TOUCHSCREENS (E.G., SMARTPHONES, TABLETS). VOICE USER INTERFACE (VUI): INTERACTS VIA SPOKEN COMMANDS (E.G., SIRI, ALEXA). NATURAL USER INTERFACE (NUI): USES GESTURES, GAZE, OR BIOMETRICS (E.G., KINECT, EYE-TRACKING). 2. HARDWARE INTERFACES ENABLE COMMUNICATION BETWEEN PHYSICAL DEVICES. PERIPHERAL INTERFACES: CON...

CPU OVERHEAT SOLUTION 

  CHECK THE CPU TEMPERATURE FROM BIOS.  IF THE CPU TEMPERATURE IS HIGH, EJECT THE CPU FAN AND CLEAN IT PROPERLY WITH COMPRESSED AIR AND BRUSH.   APPLY THE RIGHT COOLING PASTE WITH A PIECE OF CLOTH.


NOW APPLY GOOD QUALITY COOLING PASTE WITH A THERMAL COMPOUND OVER THE PROCESSOR.  ATTACH THE HEAT SINK AND FAN AND CHECK THE TEMPERATURE AGAIN.  IF THE CPU FAN SPEED IS LOW AFTER CLEANING , CLEAN THE FAN WITH ISOPROPHYL ALCOHOL, DIESEL AND WHITE PETROL.


NOW ATTACH THE FAN AGAIN CHECK THE FAN SPEED IF IT IS SAME AS BEFORE REPLACE THE FAN.


CAUSE NO 2

VIRUS 

 IF THE PROBLEM IS RELATED TO VIRUS.  INSTALL A GOOD QUALITY ANTIVIRUS SOFTWARE (AVAST, AVG AND QUICK HEAL)ETC AND SCAN THE SYSTEM.


CAUSE NO 3

RECENTLY INSTALLED A SOFTWARE, HARDWARE, DEVICE DRIVER.  DRIVER UPDATE

SOLUTION :- ASK THE USER FOR RECENTLY INSTALLED SOFTWARE, HARDWARE AND DEVICE DRIVER.  IF HE OR SHE DOES, YOU NEED TO GO TO THE SAFE MODE AND UNINSTALL THAT SOFTWARE OR DEVICE DRIVERS.

CONTROLLER CHIPS AND BUS ARCHITECTURES IN PERSONAL COMPUTER

  CONTROLLER CHIPS AND BUS ARCHITECTURES IN COMPUTER CONTROLLER CHIPS IN A COMPUTER REFER TO INTEGRATED CIRCUITS (ICS) OR CHIPS THAT ARE RESPONSIBLE FOR MANAGING AND CONTROLLING SPECIFIC FUNCTIONS OR COMPONENTS WITHIN THE COMPUTER SYSTEM. THESE CHIPS PLAY A CRUCIAL ROLE IN ENSURING THAT VARIOUS HARDWARE COMPONENTS WORK TOGETHER SEAMLESSLY. HERE ARE SOME COMMON TYPES OF CONTROLLER CHIPS FOUND IN COMPUTERS: 1.       PERIPHERAL CONTROLLER CHIPS: THESE CHIPS MANAGE THE COMMUNICATION BETWEEN THE COMPUTER'S CENTRAL PROCESSING UNIT (CPU) AND PERIPHERAL DEVICES SUCH AS HARD DRIVES, USB DEVICES, PRINTERS, AND MORE. FOR EXAMPLE, A SATA CONTROLLER CHIP MANAGES DATA TRANSFER BETWEEN THE CPU AND SATA-CONNECTED STORAGE DEVICES. 2.       GRAPHICS CONTROLLER CHIPS: ALSO KNOWN AS GRAPHICS PROCESSING UNITS (GPUS), THESE CHIPS HANDLE THE PROCESSING AND RENDERING OF GRAPHICS AND IMAGES. THEY ARE CRUCIAL FOR VIDEO DISPLAY AND GAMING PERFOR...

MOUSE TYPES AND INNER WORKINGS

 MOUSE TYPES AND INNER WORKINGS COMPUTER MICE COME IN VARIOUS TYPES, EACH DESIGNED FOR DIFFERENT PURPOSES AND PREFERENCES. HERE ARE SOME COMMON TYPES OF COMPUTER MICE: 1.      WIRED MOUSE : THIS IS THE TRADITIONAL TYPE OF MOUSE THAT CONNECTS TO THE COMPUTER VIA A CABLE. IT'S SIMPLE, RELIABLE, AND DOESN'T REQUIRE BATTERY CHANGES. HOWEVER, THE CABLE CAN SOMETIMES BE CUMBERSOME. 2.      WIRELESS MOUSE : THESE MICE CONNECT TO THE COMPUTER VIA WIRELESS TECHNOLOGY SUCH AS BLUETOOTH OR A USB RECEIVER. THEY OFFER MORE FLEXIBILITY IN MOVEMENT SINCE THEY ARE NOT TETHERED BY A CABLE. THEY REQUIRE BATTERIES OR RECHARGING. 3.      OPTICAL MOUSE : OPTICAL MICE USE AN LED LIGHT AND OPTICAL SENSOR TO TRACK MOVEMENT, TRANSLATING IT INTO CURSOR MOVEMENT ON THE SCREEN. THEY WORK ON MOST SURFACES AND ARE GENERALLY MORE ACCURATE THAN OLDER BALL MICE. 4.      LASER MOUSE : LASER MICE USE A LASER INSTEAD OF AN L...
