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 A mainframe acts as a server for storing and processing data at high speeds and can carry out millions of instructions simultaneously In contrast, supercomputers are much faster, capable of executing billions of floating-point operations in one second
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
What Is a Mainframe? Features, Importance, and Examples A mainframe is defined as a large, powerful computer typically used for complex calculations and data processing tasks It can connect to multiple end clients simultaneously so that several users can access different applications and processes running on the mainframe concurrently without impacting performance or security
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
