hello guys in today's video we are going
to study about
the types of computers
before proceeding to the lesson let's
look at the learning outcome
we are going to study about
supercomputer,
mainframe, minicomputers, microcomputers
and workstation firstly
let's study about supercomputer
supercomputer is an extremely powerful
computer
it is the fastest type of computer super
computers are very expensive and are
employed for specialized applications
that require immense amounts of
mathematical calculations
such computers have been used primarily
for scientific and engineering work
requiring exceedingly high-speed
computations
common applications for supercomputers
include testing mathematical models for
complex physical phenomena or designs
such as climate and weather evolution of
the cosmos
nuclear weapons and reactors new
chemical compounds and cryptology
as the cause of supercomputer declined
in the 1990s
more businesses began to use
supercomputers for market research
and other business-related models
supercomputers were originally used in
applications
related to national security including
nuclear weapons design and cryptography
today they are also routinely employed
by the aerospace
petroleum and automotive industries
in addition supercomputers have found
wide application in areas
involving engineering or scientific
research as for example
in studies of the structure of subatomic
particles
and of the origin and nature of the
universe the example of supercomputer is
the blue gene supercomputer
secondly let's look at mainframe
mainframes are a type of computer that
generally known for their large size
amount of storage processing power and
high level of reliability
mainframe computer is the 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
walmart india railways tesco kenya power
coca-cola and more the first successful
mainframe computer is invented
by ibm in general there are a few
characteristics of mainframes
that are common among all mainframe
vendors
nearly all mainframes have the ability
to run or host multiple operating
systems
mainframes can add a hot swap system
capacity without disruption
mainframes are designed to handle very
high volume
input and output and emphasize
throughput computing
a single mainframe can replace dozens or
every hundreds of smaller servers
this is how a mainframe computer looks alike
now let's look at the difference between
supercomputer
and mainframe firstly supercomputers are
used for large and complex mathematical
computations
meanwhile mainframe computers are used
as a storage for large database
and serve as a maximum number of users
simultaneously
secondly supercomputers are the largest
computer
meanwhile mainframe computers are
smaller than supercomputer
in size thirdly supercomputer's
speed is more than mainframe computer it
can execute billions of
instructions within a second meanwhile
mainframe computer speed is
comparatively less than supercomputers
in the millions of instructions are
executed simultaneously
finally supercomputers are the most
costly
in the world meanwhile mainframe
computers are less costly than
supercomputers
mini computer computer that is smaller
less expensive
and less powerful than a mainframe or
supercomputer
but more expensive and more powerful
than a personal computer
it is capable of supporting the
competing needs of small organizations
or
of managing networks of other computers
such as in
universities factories and research
laboratories
a server to manage organization computer
network
a mini computer may also be called as a
mid-range computer
this is the picture of mini computer
the differences between mainframe
computer and mini computer are
firstly mainframe computer has a larger
disk size
meanwhile minicomputer has a smaller
disk size
secondly mainframe computer has memory
storage of high capacity
while mini computer has memory storage
of low capacity
thirdly mainframe computer processing
speed is faster
it can process millions of instructions
per second
meanwhile mini computer processing speed
is slower as compared to mainframe
computers
lastly mainframe computer can support
from
thousand up to millions of the users at
the same time
meanwhile mini computer supports
hundreds of the users working connecting
at the same time
microcomputer is an electronic device
with a microprocessor as its central
processing unit
cpu a microcomputer uses a single
microprocessor
for its cpu which performs all logic and
arithmetic operations
it is designed for individual use a
microcomputer is smaller than a
mainframe or a mini computer
the term microcomputer is not as
commonly used as it was during the 1970s
and 1980s
we now refer to microcomputers as simply
computers
or personal computers a microcomputer's
cpu includes random access memory
ram read only memory rom input and
output
ports interconnecting wires and a motherboard
finally let's learn about workstation
a workstation is a computer intended for
individual use
that is faster and more capable than a
personal computer
it has advanced graphics capabilities
large storage capacity and a powerful
microprocessor
a workstation is used in scientific
engineering and design work
now let's look at the differences
between workstation
and microcomputer firstly
a workstation is a special computer
designed for technical or scientific
applications
meanwhile microcomputer is a personal
computer designed for regular use at a
single location
on or near a desk or table due to its
size and power requirements
secondly workstation is used to solve
high-end
technical matters such as mechanical
designing animations
engineering simulations and etc
meanwhile
microcomputer is used to perform regular
tasks
such as web browsing word processing
gaming
and etc thirdly
workstation has higher specifications
meanwhile microcomputer has lower
specifications
lastly workstation is very expensive
meanwhile microcomputer is less
expensive
