Laser printer

                      Laser Printers are also non-impact printers. These printers use
                      a laser beam to print on the paper. These printers are much
                      faster than inkjet printers and the print quality is superior.
                      However, these printers are expensive and are mainly used
                      in places where fine quality printing is required.
                                                                                                    Laser printer
                 Plotters


                 Plotters are used to print good quality drawings. They are mainly used in desktop
                 publishing offices and by architects to print building construction plans. They are
                 just like printers but are much bigger in size. They are also expensive than printers.
                 The print quality of plotters is better than printers as they print in great details.

                 There are mainly two types of plotters: Drum Plotter and Flatbed Plotter.

                 Speakers

                 Speakers are an output device that produce music, speech
                 or other sounds, from the computer. These are also used
                 for listening music and watching movies on a computer.

                     MOTHERBOARD

                 The motherboard is sometimes called the system
                 board or main circuit board. Many electronic
                 components are attached to the motherboard

                 or are built into it.
                 The motherboard contains the connectors or slots
                 for attaching additional boards, CPU and memory.

                     COMPUTER MEMORY

                 When you were a child, you were taught about alphabet and numbers. Do you still
                 remember it? How? This is so because these were stored in your memory. Just like
                 human memory, computers also have memory to store all the data and instructions
                 for performing various tasks.
