In IT industry, various kinds of computers are required to support the business and technology. It is a well known fact that computers play a vital role in industry. According to the size, power and performance these computers are classified into various types, like mainframe computers, supercomputers, micro and mini computers. These are differentiated depending on the number of users, power and size of the data and organization. Micro computers are most commonly used because they are not very expensive and are designed for personal use. While mini computers are used in small sized organizations, they are capable of supporting multiple users concurrently. But most of the IT organizations are using mainframe and super computers for their business.

In IT sector, most of the multinational organizations prefers mainframe computers to maintain vast amount of data processing. Mainframe computing, on the other hand, is used for large organizations as it is large and capable of supporting numerous users at a time. It is the suitable platform for IT industry. These mainframe computers are ranked next to super computers across the world and execute many high-end programs, due to their high-speed technology processors. These computers are very expensive and are generally not preferred by small or midsized organizations. However, many high end organizations prefer them as they consist of numerous processors, which provide high speed to the system to increase the business efficiency.

Mainframe increases the capacity of features and functions; it also increases the flexibility and security. It is growing in IT industry and can reach the application demands on the same lines as a data server.  The main difference between super computers and mainframe computers is that the super computers are optimized and have the power to implement only some programs rapidly, but the mainframe computers have the power to perform many programs simultaneously. Due to this reason, many IT organizations choose mainframe computers rather than super computers. As compared to super computers, these are cost effective and support multiple users at a time. These days every enterprise needs the best system to get the best performance in their business. They also prefer low cost systems and servers. In that case, mainframe is most efficient for IT organization so as to provide cost effective solutions and endow with outstanding performance in their business needs. These are affordable by small or midsized enterprises, whereas super computers are expensive. Mainframe computers are used in financial services also to improve the growth of their business.
