Top 20 Examples of Digital Computers | Uses of Digital Computers

Through this article, you will fully educated about many examples of digital computers and applications where are going to use of digital computers in daily life with ease. This is unique post over the internet. Making ensure, at the end of this article; you will definitely completely aware about examples of digital computer and its uses without hassle.

Introduction of Digital Computer

A digital computer is an electronic device that keeps storing data into numerical form and executes all tasks on that data with helping mathematical manipulation. Digital computer requires the input data that it can get process, and then it brings up the output data. These types of digital computers are able to perform various kinds of operations with in less time duration, and they are trust-able as well as performing all work for continuous periods without getting any exhaustion.


The digital computer receives the input that is easily understandable by the users, and this input is going to convert into machine language; it is also easily understand to user. All input and output of digital computer are presented into binary code (0 and 1).

Personal Digital Assistant

Personal Digital Assistant is also best example of digital computer because they are hand handled devices such as data organizers, Mobile Phones, Personal Digital Assistant etc.

Personal Digital Assistant was introduced before the development of smart phones

Users perform several tasks with using of those devices such as to gather data, watching movies, playing games, and can be used internet.

In Personal Digital Assistant, to feed the input via its touch screen interface, and its data is hold in the memory card


Calculator is very eminent example of digital computer that is used in the real life.

We use calculator in daily life because it helps to solve several mathematical and scientific mathematical problems.

In this calculator, we insert the input through keypad that is placed on the surface, then it performs various functions such as addition, subtraction, multiplication, division, and other scientific functions, then it delivers result on the LCD.

Now these days, scientific calculators are getting more popularity, and it contains very high performance processor, so it is able to execute various complex mathematical operations.

Digital Camera

Digital Camera is also very eminent example of digital computer.

Now these days, mostly we use digital camera with their several features, but these features were not existed in the traditional camera because in currently digital cameras, embedded system is integrated in them.

It contains various components with enabling DSP processors.

It has three functions like as capture image, store image data, and to represent that data.

Digital Camera enables different types of memories such as DRAM, memory card, flash memory with controller etc.

In Digital Camera, all images are saved and to get process in the form of digital data in bits form.

So, no require of film to keep save images. Due to this feature, you can easily enhance storage capacity along with easily to move image.

Digital Clock

Digital clocks show you time on the screen directly in the form of numeric digits. They provide the result at better accuracy and not more costly. Today, timekeeping mechanism of both digital and analogue clocks is usually similar. And, both are used of quartz crystal. In digital clock, it is use of integrated circuit that works along with digital data. Therefore, digital clock is the most eminent digital computer device that is used in your daily life.

Automatic Washing Machine

Washing Machine is also one of famous daily life example of digital computer.

Almost, Washing Machine is available at every home because it is used for washing dirty clothes.

You out all the dirty clothes inside the machine and push start button i.e. you input data.

Washing Machine to determine the weight of clothes that you have put inside it

Then, you have to insert clean water inside it.

Washing Machine’s valve gets off, after completing its load and water level.

Now, inside Washing Machine, to get rotate drum and to start clothes washing

When, your clothes are washed then outlet valve on to get free all dirty water.

The sensor determines that dirty water has been released or not, and on or off outlet valve.

Home Electronic Equipments

There are many home electronic equipment devices, which are used in your real life like as refrigerator, microwave, vacuum cleaner, and more. Advance refrigerator is designed with using of a digital invertor compressor that lets the compressor to get adjust the cooling speed as per the need. Same as, microwave ovens are designed with digital counters and temperature sensor that provide the better functionality than to old technology ovens. Therefore, mostly our life is dependent on the digital computers.


Most of operations are performed inside the automobile, which are dependent on digital computer such as wielding the smart rear-view mirror, playing music, accessing GPS, and so on.

ATM (Automated Teller Machine)

Everybody is known about ATM, that machine is used for withdrawing cash.

Almost, all banks have their ATM machines, which are located at the different location.

How does work it- Firstly you have to swipe your ATM card in ATM machine then insert your password, and you get your cash.

Smart Phones

A smartphone is also real life example of digital computer that consists of a memory unit, processor, and I/O devices installed on the printed circuit board. The processor grabs the real-life input from the user; then converts it into digital format, processes it and then output data into user understandable form.

Desktops, Laptops, and Notebooks

With going to advancement in technology, most of devices have switched into digitization. Traditional, personal computer performed all tasks on analogue technology. So they were getting to slow speed, less signal quality, low precise; but now digital computers assisted overcomes as these drawbacks along with offering extra features like as portability, great information storage, better flexibility, and so on.
