Question: ……….. computer are of large size

Answer:

The term you are referring to is "mainframe computer."

Mainframe computers are large-scale computer systems designed to handle vast amounts of data processing and support multiple users concurrently. They are known for their high performance, reliability, and scalability, making them suitable for organizations that require robust computing capabilities.

Mainframe computers are characterized by their physical size, as they typically occupy dedicated rooms or data centers due to their extensive hardware components. They consist of multiple processors, extensive memory capacity, high-speed input/output channels, and specialized operating systems.

Mainframes are capable of processing large volumes of transactions and supporting numerous users simultaneously. They are often used in industries such as banking, finance, government, healthcare, and large-scale enterprises that handle critical data and require high levels of processing power and reliability.

Some key features and uses of mainframe computers include:

1. Batch Processing: Mainframes excel at handling batch processing, where large volumes of data are processed in batches without the need for immediate user interaction. This is commonly used for tasks such as billing, payroll processing, and large-scale data processing.

2. Online Transaction Processing (OLTP): Mainframes are capable of handling real-time transaction processing, providing rapid response times for online transaction systems like banking, airline reservations, and e-commerce platforms.

3. Virtualization and Partitioning: Mainframes have advanced virtualization capabilities, allowing them to run multiple operating systems and partition resources to support different workloads concurrently.

4. High Availability and Reliability: Mainframes are designed with redundant components and failover mechanisms to ensure high availability and minimize downtime. They often incorporate features like hot-swappable components and extensive backup and recovery options.

While mainframe computers are large and complex, they continue to be relevant and widely used in industries that require massive data processing, security, and high availability. They complement other computing platforms and are often integrated into modern hybrid IT infrastructures to handle critical and demanding workloads.
