Midrange systems are computer systems that fall between mainframe computers and personal computers in terms of size, power, and cost. They are designed to handle moderate workloads and support multiple users simultaneously, making them suitable for small to medium-sized businesses. These systems often run on various operating systems and can manage tasks like data processing, transaction management, and application hosting. Typically, midrange systems are known for their reliability and scalability. They can be easily upgraded to accommodate growing business needs. Examples of midrange systems include IBM AS/400 and HP 3000, which provide robust performance for various applications while remaining cost-effective.
