What Is a Mainframe Computer and Its Types?

Mainframes are a type of computer that’s used to run large-scale, high-volume business applications. They can handle millions of transactions per hour and can process data faster than servers or workstations.

Mainframe Computer Definition

A mainframe computer is a large, powerful and expensive (read: very expensive) computer that performs high-volume transaction processing. They’re used in situations where the data flow is so massive that other types of computers cannot process it.

Mainframes are used for large-scale applications such as airline reservations, banking and financial services, manufacturing and retail industries. Mainframes can handle thousands or even millions of users simultaneously.

Mainframe computers are also called “big iron” because they require lots of energy to run efficiently. To put their size into perspective: A typical mainframe server will weigh 10 tons (9071 kilograms).

What Is a Mainframe Computer?

You are most likely familiar with personal or desktop computers. These smaller devices have a single processor and can be used to perform many tasks, including word processing and running other programs.

The mainframe is a large computer that runs on various operating systems, such as Linux and Unix, in addition to Windows Server 2003/2008/2012/2016. The mainframe has multiple processors that work together to process large amounts of data at one time. As a result, it is ideal for businesses that need their information processed quickly and efficiently by several users at once (e.g., hospitals).

Mainframe Computer Characteristics

Mainframe computers can be described as large and powerful. These are used in large organizations that perform complex calculations, high-volume transactions and other data processing tasks. Mainframes are expensive, so they’re only found in organizations that need the power.

Banks, airlines and government agencies typically use mainframes. They’re also used by large companies such as Walmart or Amazon because they can handle enormous amounts of transaction volume with ease.

As per a web development expert Micro Focus, “Despite advances in technology, mainframe-hosted systems remain business-critical, and at the heart of enterprise computing. Nothing else matches their levels of performance, consistency, and reliability.”

Types of Mainframes

You must be wondering what the mainframe computer is. Well, it is a large computer with a high-speed memory that performs complex calculations and processes multiple tasks simultaneously.

Companies use mainframes to run several business applications simultaneously on one machine. They are also used for large-scale data processing, such as e-commerce sites and banks use them to process millions of transactions every day.

Mainframe computers have been in use since the 1950s. However, they are still being used today because of their performance ability compared to other types of computers like personal computers or laptops, which have limited memory capacity and slower processing speeds compared to mainframes.

Many types of mainframes are available today like IBM System z, IBM Power Systems (IBM System p), HP 9000 series 300/400/500/700/800/900 systems (HP 3000 series) and Fujitsu BS2000 family processors.

Mainframes are large computers that can support multiple users and applications. Mainframe computers have been around for decades, but their use remains important in today’s tech-driven world. Several types of mainframes exist today, each offering unique features and functions to businesses needing them.
