Embedded Computers

                  An embedded computer is a special type of microprocessor-based system that is developed for
                  performing a specific task. It is different from a general-purpose computer. Today, embedded
                  computers are used in various applications. Some commonly used examples of  embedded
                  computers are the digital camera, microwave,  ATM, etc. Let us  learn about some  of these
                  embedded computers in detail.

                  Digital Camera
                  The digital camera  is one of the most commonly used embedded
                  computers. With tiny computers built inside them, modern cameras are
                  now very smart and have many new features that old cameras didn't
                  have. The main functions of a camera are to capture photos and shoot
                  videos. It also has a memory to store the captured photos and videos.
                                                                                                    Digital Camera
                                                 ATM

                                                 An Automated Teller Machine (ATM)  is  another example of an
                                                 embedded computer  that allows us to withdraw money from our
                                                 bank account anywhere and anytime. This machine is connected
                                                 to the bank’s server. When a user withdraws some money from an
                              ATM                ATM, an equal amount is debited from our bank account.
                  Microwave

                  The microwave  that  we  use at  home is also an  example of an
                  embedded  computer  that  allows user to  warm  and  cook food.
                  It contains a computer system embedded inside to control the time
                  and temperature.
                  Handheld Computers                                                                  Microwave

                  A handheld computer is a type of computer that can easily be stored in our pockets and used by
                  holding it in the hand. Most handheld computers have a touchscreen on which data can be input
                  using our fingers. Some commonly used examples of handheld computers are smartphones,
                  smartwatches, PDAs, and gaming consoles.

                                 Smartphone

                                 A smartphone is a type of mobile phone that provides the facilities of a computer. It
                                 has a touchscreen and a rechargeable battery. A smartphone provides the features
                                 of an earlier cell phone and also some advanced features similar to a computer.
                                 The size of the smartphone is smaller than that of a tablet computer. Therefore, a
                                 smartphone can easily be carried in a pocket.

                  PDA

                  A Personal Digital Assistant (PDA) is a handheld computer that has a touchscreen
                  and allows us to organise our daily routine work like schedules, calendars, and
                  address book information. It also has a pen-like stylus that allows users to
                  input data. It can also accept handwritten input directly from the touchscreen.
                                                                                                             PDA
