  Liquid Crystal Display Monitors
                The LCD monitor is  the advanced form of CRT monitor. A cold
                 cathode ray and the  uorescent panel are two major components of

                 the LCD.  The cold cathode ray technology is used in LCD which
                 emits electrons and lights up the  uorescent-coated monitor screen.
                 The process is known as backlighting. The second component is a
                  uorescent panel, which is made up of liquid crystal.  iquid crystals
                 is current-sensitive and determines the number of electrons to pass
                 through the screen to make the shape and image of an object.

                                                     Light Emitting Diode Monitors

                                                     Light Emitting Diode (LED) is an improved version of the LCD
                                                      monitor and the manufacturers have tried to eliminate the
                                                      drawbacks of LCD monitors. Both the monitors are based on the
                                                      same display technology and provide better resolution. However,
                                                      the difference comes in backlighting as LCD monitors use Cold
                                                      Cathode Fluorescent Light and LED monitors are based on light
                                                      emitting diodes.

              The backlighting impacts badly on the image and decreases its sharpness and brightness. WLED and RGB LED
              are the two types of LED monitors, depending on the way the LED is placed in the panel.

              Benefits of LED over CRT and LCD Monitors

              LED monitors give a high-quality image with vibrant colors and viewing comfort. LCD monitors are unable
              to display black and white images while LED monitors are capable of producing true black hues. It consumes
              less electricity than CRT and  CD monitors as a cold cathode  uorescent lamp is embedded in the panel. The
              absence of mercury makes it eco-friendly while zero percent  ickering removes the chances of strain on the
              eyes.

                COMPONENTS OF CPU BOX

              CPU box consists of various hardware components present inside it. The hardware in the CPU box are
              Memory and Storage Devices, Main Circuit (Motherboard), Power Controller (SMPS), Processor, Ports,
              Cards, etc.

              Memory and Storage Devices

              Memory, in the context of a computer system, refers to the location of storage of information. The CPU stores
              the data in the memory/storage device that can be used or retrieved whenever required.

              Memory receives instructions and data from the input devices and stores them till they are needed by other
              parts of the computer. Once the instructions are executed, the results are transferred to a permanent location
              which are then stored in a storage device.

              Memory can be classified into two types:

               Primary Memory                                          Secondary Memory
