What is Mainframe Computer? Mainframe computer likes as a big centralized machine that contains the large memory, huge storage space, multiple high grade processors, so it has ultra processing power compare to standard computer systems. So, mainframe computer system’s importance is increasing for large scale organization, scientific research, consumer statistics, and census data, because it is capable to execute multiple complex programs concurrently at the ultra speed.
Who Use Mainframe Computer? Mainframe computer is best platform to execute millions of transactions in every single second. So mainframe computers are used in the large scale organization, because they have to need for processing the massive data at once in every second. There are some companies, which are used to mainframe computer system such as Wallmart, HSBN, Indial Railways, ICICI and HDFC banks, Tesco, Kenya Power, Vodafone, AIG, Coca Cola, RBI, DHL, FORD, NASDAQ, Nike, Tata, Travelport, UPS, USA Pstal Services, and more.
Components of Mainframe Computer There are some major components of mainframe computer because they play vital role to improve the entire outstanding performance of mainframe computer system. • Processing Unit • Controller Unit • Storage Unit • Multiprocessors • Motherboard • Cluster Controller System • Input/output Channels
Functions of Mainframe Computer Working of mainframe computer is divided into different segments, below every segments are described. • Data Warehouse System • Preserve Authentication Access Permission • Allot Processor Time Frame

Features of Mainframe Computer • Mainframe computer allows to process huge amount of data simultaneously without getting any malicious attacks. • Mainframe computers are more popular due to their long life performance, because it can run smoothly up to 50 years after its proper installation. • Mainframe application programs get outstanding performance due to their large scaled memory management. • Mainframe computer systems are capable to share their over workload on the other multiple processors and I/O terminals, and due to this process enhances its performance.
Characteristics of Mainframe Computer • Mainframe systems are designed to support “Tightly Coupled Clustering Technology”, due to this feature; it can manage approximate 32 systems along with single system image. If system gets fails due to any hardware component damage then running tasks could be shifted to other live system, and any data do not corrupt in this entire process. • Mainframe system is eligible to support maximum input/output devices. • Mainframe system is able to execute multiple programs concurrently. • In mainframe system, virtual storage system can be used. • It can generate I/O bandwidth in large amount. • It supports to Zero fault tolerant mobile computing system. • It is capable to manage several users. • It can also support centralized computing system.
Advantages of Mainframe Computer There are many benefits of mainframe computer, below shown all: • • • • • • •
Ultra Computing Power Scale-ability Virtualization System Reliability Self-Serviceability Protection Flexible Customization
Disadvantages of Mainframe Computer • Mainframe computer system requires the more space and less temperature. • If, any errors or bugs are occurred while performing the massive task, then need the well trained staff for eliminating the errors. • Entire system can gets down due to major damage of hardware component’s system. • Difficult to read its instructions which are used on the command based interface. • It Consume more resources.
