Mainframe computer - Wikipedia
A mainframe computer, informally called a mainframe or big iron, [1] is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing.

What Is a Mainframe? - IBM
The term mainframe initially referred to the large cabinet or ‘main frame’ that held the central processing unit (CPU) of early computer systems. The mainframe served as a central data repository or ‘hub’ that links workstations or terminals in an organization’s data processing center.

What is a mainframe? It's a style of computing - IBM
A mainframe is the central data repository, or hub, in a corporation's data processing center, linked to users through less powerful devices such as workstations or terminals. The presence of a mainframe often implies a centralized form of computing, as opposed to a distributed form of computing.

What is a Mainframe Computer? - GeeksforGeeks
Mainframe computers are a type of computer designed for high throughput, which means processing data as fast as possible. They are primarily used for transaction processing, which involves a set of operations like disk read and write, operating system calls, and data transfer between subsystems.

The IBM mainframe: How it runs and why it survives
Mainframe computers are often seen as ancient machines—practically dinosaurs. But mainframes, which are purpose-built to process enormous amounts of data, are still extremely relevant today.

What Is a Mainframe? Features, Importance, and Examples
A mainframe is a powerful computer that connects to multiple end clients so that users can access apps concurrently.

What Is a Mainframe? | Definition from TechTarget
A mainframe, also known as big iron, is a high-performance computer used for large-scale, compute-intensive purposes and tasks that require greater availability and security than smaller-scale machines. Historically, mainframes have been associated with centralized rather than distributed computing.

Mainframe | Definition & Facts | Britannica
Mainframe, digital computer designed for high-speed data processing with heavy use of input/output units such as large-capacity disks and printers. Mainframes have been used for such applications as payroll computations, accounting, business transactions, information retrieval, airline seat

IBM z17: The First Mainframe Fully Engineered for the AI Age
IBM announced the IBM z17, the next generation of the company's iconic mainframe, fully engineered with AI capabilities across hardware, software, and systems operations. Powered by the new IBM Telum® II processor, IBM z17 expands the system's capabilities beyond transactional AI capabilities to enable new workloads.

Mainframe Services and Solutions - DXC Technology
But managing mainframes takes ongoing investment in software, hardware, facilities and support. DXC Technology can take over the hard work of operating and supporting your mainframe solutions — from monitoring and remote infrastructure management to full-service management. That includes mainframe hosting services, storage and disaster recovery.
