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.
Smartphone
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.
