In this PPT, we are going to explore in detail information about mainframe computer with their definition, example, types, uses, features, advantages, disadvantages and thier related FAQs!!

1. 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.

2. 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.

3. 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

4. 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

5. There are several examples of different types of mainframe computer.
• Types of Z Series Mainframe Computer
• IBM z15
• IBM z14
• IBM System z13
• IBM z Enterprise System
• IBM System z10
• IBM System z9
Other Types of Mainframe Computer
• Tianhe-1A; NUDT YH Cluster
• Jaguar; Cray XT5
• Nebulae; Dawning TC3600 Blade
• TSUBAME 2.0; HP Cluster Platform 3000SL
• Hopper; Cray XE6
• System z9
• System z10 servers

6. • Health Care Sector
• Defence Sector
• Education Sector
• Retail Industry
Other Applications are:
• E-Business
• Banking Sector
• Stock exchange
• Research Center
• Ticket reservation in railway and airlines
• Credit card Verification Insurance Sector
• Telecommunication
• Finance Sector

7. • 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.

8. • 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.

9. There are many benefits of mainframe computer, below
shown all:
• Ultra Computing Power
• Scale-ability
• Virtualization System
• Reliability
• Self-Serviceability
• Protection
• Flexible Customization

10. • 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.
