Life with computers is way easier as compared to one without them. By the grace of computers, what seemed impossible yesterday is possible today. If you underestimate my statements, you are probably unaware of the role of computers in our lives. And it is not just about our lives, Computers have also simplified the way we do business.
Sure there are tons of computer breeds taking active roles in evolving the business methodologies, but none comes with enormous operational capabilities.
Currently, the only type of computer that determines the course of businesses is Mainframe Computers. Get the Mainframe Computers out of the system and a number of industries would collapse. Okay fine, now you know the power of Mainframe Computers and possibly be relating them with your pillow-sized Personal Computers.
But no, Mainframe Computers are way different than Personal Computers both in terms of size and power capacity. The following content will take you straight to the world of Mainframe Computers where you will learn about its definition, features, and uses.
What Are Mainframe Computers?
Mainframe Computers are a type of computing machine that perform millions of mathematical calculations per second. Known for their hyperfast data response and fridge-sized body, Mainframe Computers are mostly deployed to regulate communications and transactions of large-scale businesses.
Based on unique computing architecture, Mainframe Computers can run multiple operating systems simultaneously while offering real-time computing solutions. They secure the second spot in the list of the fastest computers with Supercomputer being on the top.
How Does A Mainframe Computer Work?
Frankly speaking, Mainframe Computers take their work seriously which can be seen in their performance. You make a request to a Mainframe Computer and it would come up with an output instantly. This super-fast output or result makes one wonder about the working mechanism of a Mainframe Computer. Let’s dig into it and know the science behind it.
Firstly, it is important to know that a Mainframe comprises three main components that make it what it is. These are namely the Central Processing Unit (CPU), System Assistance Processor (SAP), and Input/Outputs (I/Os).
To give you a bit of an idea, the CPU is the brain of the Mainframe Computer and SAP is the middle man that connects the CPU with the I/Os. What about the poor I/Os? Well, these are small-sized CPUs that get the input data from the CPU and process it to generate the output data.
Now the picture is getting clearer and you are easily going to understand the working mechanism of a Mainframe Computer. When the CPU of the Mainframe Computer registers the input data, it shares it with the SAP for further processing.
As a crucially important software of the Mainframe Computer, SAP analyzes the input data and forwards it to right I/Os aka small CPUs. After getting the Input data, I/Os process it, generate the output data and send it back to the CPU.
Features Of Mainframe Computers
The following are some of the significant features offered by Mainframe Computers.
A Mainframe Computer owns multiple CPUs to process enormous amounts of data and generate the output in real-time. These Central Processing Units provide ultimate power, unimaginable speed, and accuracy to the Mainframe Computers. As the brain of the Mainframe Computers, the CPUs dictate all instructions to the SAPs and the small CPUs for data output.
A Mainframe Computer is based on a centralized server in direct communication with multiple operating systems. Server centralization allows a Mainframe Computer to split the operations into a number of tasks and share it with each operating system for enhanced performance.
Secured Data Access
Mainframe Computers are quite good at managing strict security. They are so good at their job that no unauthorized individual can infiltrate its database. Mainframe Computers only entertain authorized individuals to access their database making them privacy-friendly computers.
In terms of operating systems, Mainframe Computers don’t have to deal with the issue of incompatibility. In fact, they are compatible with all types of operating systems. This comes as a huge advantage for the application developers who can design applications for the specific operating systems and use them in Mainframe Computers.
Uses Of Mainframe Computers
Mainframe Computers are used in multiple sectors which include the following.
In the banking sector, Mainframe Computers take care of millions of transactions each day. In connection with the ATM machines, the Mainframe Computers track the activities of the customers and respond to their requests.
Additionally, Mainframe Computers are also used by the militaries around the world. Military forces use Mainframe Computers to set up a line of instant communication between and among its various components and to perform intelligence activities.
Mainframe Computers are commonly used by academic institutions to store the data of students and faculty members. It also allows the institutions to gather the data in a centralized manner and make it easily accessible for the use in future.
Mainframe Computers provide safe and secure storage facilities for researchers to store their research-related content. It allows the readers and other researchers to find the potential data they look for and make use of it.
When it comes to the health care sector, Mainframe Computers assist medical professionals in generating test results and MRI reports. By providing quick data output, they speed up the process of treatment and improve the health care sector.
Frequently Asked Questions
From the perspective of banking and health care, Mainframe Computers are too important to be deployed. They are stabilizing e-commerce, transforming businesses, and providing us with an affordable storage solution equivalent to a cloud.
If Mainframe Computers keep up with the same pace to serve the businesses, they would devalue cloud computing and may remain in the spotlight for the next few decades.
