What is the difference between machine and device ?

@hsirah5 • 24 May, 2012 Just like the difference between an element and a compound in chemistry terminology... Machine can be a single simple tool or a combination of tools, while a device is a tool developed using few or more simple machines aimed at a specific action/procedure...
E.g:- An iron rod that can be used to move or roll an object is a simple machine; while a hydraulic car-jack that is used to raise the chassis of the vehicle is a device.
Hope this gives a good idea.. 😎

@pratap singh, upendra • 24 May, 2012 • 1 like usually a machine is an elementary unit that can perform a variety of operations depending upon the tools that it consists of; on the other hand a device is sophisticated version that is designed for a particular usage.

for example i n the above conservation, the iron rod is a machine as it can perform a variety of functions like moving an object or lifting it and many other functions that are not incorporated in a hydraulic jack. However a hydraulic jack has got a definite purpose and design.

Machine is thus a fundamental building block of device and the same machine could be used is a number of different devices. However, converse is not true

@zaveri • 26 May, 2012 i think they mean the same.

a machine refers to something mechanical and has moving parts.

a device is something electronic and kind of static.

@Ramani Aswath • 26 May, 2012 In my opinion these are matters of covention.
In biomedical technology a simple pvc tube cut to length and delivered sterile can be a class ii medical device as also an MRI machine.
Device can mean many things depending on the context. A machine is usually restricted to something that can be used to perform some mechanical function.
This article gives some info on the diversity of devices.

@Anthony Jarmie • 26 May, 2012 Hello friends,

Machine is anything which reduces human effort while device is used to make machine operations smooth. Every machine is a device, but every device is not a machine.

Best regards

@Sourabh Sandal • 21 Aug, 2013 Any opinion about Transformer.Is It a machine or device?

Any opinion about Transformer.Is It a machine or device?

Its a device which usually used to step up or step down voltage to required voltage.

@lal • 21 Aug, 2013 • 1 like Tranformer is also called as constant flux 'machine' or constant power 'machine' 😁

@Naman Agarwal • 09 Sep, 2013 A machines is a device capable of continous electrmechanical energy conversion like motors , generators. That's why , according to this definition, transformers are not considered as machines since they are only changing the level of electrical energy.

@Anoop Kumar • 09 Sep, 2013 Why to complicate things?? 😨

If I am not wrong we refer device which can be carry along by a person.
GPS device, mobile device, etc.

and machine is of-course , man made things which help you to reduce human effort.

what is the difference between machine and device ?

1. machine is any thing which reduces human effort while device is used to make machine operations smooth.
2. every machine is a device but every device is not a machine.1. machine is any thing which reduces human effort while device is used to make machine operations smooth.

A machines is a device capable of continous electrmechanical energy conversion like motors , generators. That's why , according to this definition, transformers are not considered as machines since they are only changing the level of electrical energy.

Then why is a computer called machine? 😁 There isn't any electromechanical energy conversion as in motors and generators in a computer!

An IC engine is a machine too. There isn't any electromechanical energy conversion in that either!

A tranformer is sometimes called 'the most efficient machine'!

@Jeffrey Arulraj • 11 Sep, 2013 Machine may be an interconnection of devices to increase the efficiency of the work performed

Device is the simple building blocks of machines

knowledegeable persons dont't call computer a machine...That is leyman language ..

Ask a person who work/play with computers for 10 hours a day, you will get the answer 😉

@Naman Agarwal • 04 Oct, 2013 Seems like u never worked on computers. Thats why u are indulging another person. Nevertheless let me tell u...comupter is not a machine...further u know...

@Anoop Kumar • 04 Oct, 2013 Probably, yes sire, because I am posting this from Lisa.☕

@lal • 04 Oct, 2013 So, what is 'machine language'? 😁 Should be a layman's term too!

@yogi.bharadwaj • 05 Oct, 2013 i think m/c is the device which requires some king of input supply of any kind its electrical or mechanical but a device may be any thing it also includes machine or the mini parts of the machine or the whole machine is device. and a machine always lessen the human effort but a device can't be in this category.but human needs both machine and device but we can say that all the machines are the device but all devices can't be machine.if i am wrong pls correct me friends.

@Dinesh Patra • 11 Oct, 2015 I think machine has moving parts but devices may have both static or moving parts capable of some type of conversion action definitely.

@Gohanamis • 03 Dec, 2015 A machine has moving parts, a device can be anything that reduces human effort whether it has moving parts or not.

Examples of a machine are: an elevator, automobile, or a personal desktop computer (it has fans, which are moving parts).

A device can be a hammer, crowbar (though they can be moved, their nature as a tool is to remain static) or a cellphone/smartphone/tablet (but once you add something like a cooling fan, it would become a machine).

@Mohana Chandra • 24 Feb, 2020

Machine:

• Machine has moving parts like pulleys,lever,screw,axle etc .Means that, machine is combination of the moving parts.
• Machine reduces the human effort,cost and time
• Every machine is a device.
• Eg: Clock ,Calculator etc.

 Device:

• Device can be the combination of machines that designed to perform specific task.
• Device can be Mechanical or Electrical tool.
• Every Device is not a machine.
• Eg: Printer,Keyboard,Computer etc.
