Difference Between Edge Computing and IoT

First, we have to discuss the terms Edge computing and IoT. And their prior usage in replacement of other digital gadgets we are using right now. IoT is abbreviated as the Internet of Things (IoT), and the use of this is very much explainable in an upcoming discussion.

The IoT device mainly collects all the required information from an object and it sends to an edge device rather than sending it directly to a central server…

Edge Computing is also important if we about its use in daily routine. And edge computing has its own benefits in daily routine. An edge computing device receives the data, analyzes the data, and gives quick required results. 

So in this way the IoT device’s capabilities with edge computing analytics. That provides detailed information in a quick time.

Edge Computing vs IoT

Edge computing devices do not have these sensors and it may be optional. They are just like normal computers which can analyze data.

Edge computers, on the other hand, are PCs with operating systems, memory management, and processors. They may not use the processing power efficiently and are prone to attacks. Still, you can update these devices and use them for many functions. 

Again a point here is data processing which is done locally in edge computing. And edge computing provides decentralized data processing.

On the other hand, both devices may have so many similarities but at the same time, they have some differences as well. And they have totally different technologies to be used in them.

Device Capability is the main difference in IoT as it requires internet access. And mostly IoT has different sensors which they use for receiving and transmitting the information.

These devices have specific functions. And they do not have operating software. IoT devices are less vulnerable to cyber-attacks on them. They cannot be updated easily.

What is Edge Computing?

Edge computing is a structural design that handles computing nearer to the data. This means data is evaluated precisely at the gathering point. The same computing device collects and analyzes the collected data so that results can be received quickly.

Edge computing has the biggest advantage that we can get real-time control of our important processes. It also reduces limitations and network disruptions that are detrimental to critical business decisions. 

Edge computing provides instant analytics of data. Let’s take a few examples of edge computing to understand the practical application. Many manufacturing and factory operations use edge computing to collect real-time data analytics about different processes.

Edge computing collects and analyzes information about different fields e.g. agriculture it collects data regarding crop growth, quality of soil, sunlight crop needs, and many more.

These are some examples of edge computing applications. As we can say that edge computing can appear similar to the IoT but they are not the same by any means.

What is IoT?

If we talk about IoT, it is actually abbreviated as the internet of things, The Internet of Things (IoT) is an ecosystem of different interconnected items. This system consists of physical, digital, electrical, and computing devices.

And each of the devices has unique identifiers (UIDs) and through these UID different devices communicate with each other on a connected network.

IoT is actually a device or ecosystem which connects the world through its working capacity.

Home automation is a key in IoT applications. You can connect your everyday gadgets for example thermostats, fans, and lights. This enables you to turn the IoT ON/OFF from a distance. 

Factories use IoT for automating many tasks. Primarily, they use IIoT (Industrial IoT) to control devices and get key performance metrics from them. Smart factories also influence IoT to systematize tasks in a manufacturing pipeline. None of these tasks require any human intervention.

In Supply Chain we can use IoT devices to track item locations in a real-time way. Based on the information collected through IoT devices managers collects from them, they make e decisions regarding different supply requirements of items.

Many more examples we can code here but I’m sure it’s been clear given you a clear idea of how common and useful the IoT is.

Main Difference Between Edge Computing and IoT

  1. Edge computing does need an internet connection for its working
  2. Edge computing can be locally operated but not IoT
  3. IoT is more specific to its functions but edge computing does any function
  4. IoT saves you from cyber attacks
  5. Edge computing is multi-tasking but IoT not
