Mainframe Computer with its Example, Types, Uses, and Features!!

1
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 systems
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
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

4
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

5
Examples of Mainframe Computer

• 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

6
Applications Uses of Mainframe Computer

• 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

7
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.

8
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.

9
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

10
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 components system.
• Difficult to read its instructions which are used
  on the command based interface.
• It Consume more resources.
