this is about computer

2. • A computer is an electronic
device that was discovered by
Charles Babbage. He is known as
the father of computers. There
are various parts to a computer.
The four major parts of a
computer are the mouse,
keyboard, monitor and CPU. With
computers, we can send and
receive messages through emails
and save important information.
It helps to store and modify
data. Nowadays, computers are
used in schools, banks, offices,
etc., and it is now impossible
to survive without computers. In
order to run any organisation,
institution, or any other
office, a computer is a must.
Computers have made life easier
for people of different age

3. TYPESOFCOMPUTER
•There are six types of computer

4. • A microcomputeris a completecomputeron a small
scale, designedfor use by onepersonat a time. An
antiquatedterm, a microcomputeris nowprimarily
called a personalcomputer(PC),or a device basedona
single-chipmicroprocessor.Commonmicrocomputers
include laptopsanddesktops.BeyondstandardPCs,
microcomputersalso include some calculators, mobile
phones,notebooks,workstationsandembedded
systems.
• Smaller thana mainframeor minicomputer,a
microcomputeruses a single
integratedsemiconductorchipfor its central
processingunit (CPU).Theyalso containmemoryin the
formofread-onlymemory(ROM)andrandomaccess
memory(RAM),input/output(I/O) ports,anda bus or
systemofinterconnectingwires, all housedin a single
unit usually referredto as a motherboard.

5. • We all know the computer. it is one of the biggest
inventions of modern science. The laptop is a
smaller version of a computer. It does the same
work as a computer. But there are so many benefits
and advantages to having a laptop. It is easy to carry
and it can be used remotely. You can carry this
machine anywhere with you. You can keep that on
your backpack or there are some different bags for
laptops. There are built-in mouse and keyboard in it.
You don’t need to use any portable keyboard or
mouse. But if you want to use one, you can use
because it has so many USB ports. The LCD screen
of a laptop is so good and it is almost like a portable
LCD monitor. It is also known as a notebook
computer. The use of a laptop has made the
education sector so much easier. Now, most of the
international universities are providing their lessons
through it. If you have got one, you don’t need any
books. You can read and write on it.

6. • A minicomputer, or colloquially mini, is a type of
smaller general-purpose computer developed in the
mid-1960s[1][2] and sold at a much lower price
than mainframe[3] and mid-size computers
from IBM and its direct competitors. In a 1970
survey, The New York Times suggested a consensus
definition of a minicomputer as a machine costing less
than US$25,000 (equivalent to $188,000 in 2022[4]), with
an input-output device such as a teleprinter and at least
four thousand words of memory, that is capable of
running programs in a higher level language, such
as Fortran or BASIC.[5]
• The class formed a distinct group with its own software
architectures and operating systems. Minis were
designed for control, instrumentation, human
interaction, and communication switching as distinct
from calculation and record keeping. Many were sold
indirectly to original equipment manufacturers (OEMs)
for final end-use application. During the two-decade
lifetime of the minicomputer class (1965–1985), almost
100 companies formed and only a half dozen
remained.[6][user-generated source]

7. SUPER COMPUTER
• The invention of supercomputers is regardedas the marvelous
innovation of creativeminds. It is becauseof its enormous
capabilityof working it has got its name as supercomputers. The
normal computers that we use in our daily lifeare used to make
our work easier and faster. We take the help of computers in
performing different calculations and tasks that are performed
by us in our daily life. The workingof supercomputers is totally
different from the normalcomputers that we use in our dailylife.
Normal computers are capable of doing different tasks one by
one but the sameis not applicableto supercomputers.
• Supercomputers havethe capabilityof performing millions of
calculations or tasks at one time. Normal computers work with
the conceptof serial processingthat enablesthem to perform
tasks one by one. On the other hand, supercomputers work with
the concept of parallel processing that enables them to perform
millions of tasks at one time. This makes supercomputers more
efficient than the norma

8. • A tablet computer, commonly shortened to tablet, is
a mobile device, typically with a mobile operating
system and touchscreen display processing circuitry,
and a rechargeable battery in a single, thin and flat
package. Tablets, being computers, have similar
capabilities, but lack some input/output (I/O) abilities
that others have. Modern tablets largely resemble
modern smartphones, the only differences being that
tablets are relatively larger than smartphones, with
screens 7 inches (18 cm) or larger, measured
diagonally,[1][2][3][4] and may not support access to
a cellular network. Unlike laptops (which have
traditionally run off operating systems usually
designed for desktops), tablets usually run mobile
operating systems, alongside smartphones.

9. •The computer is one of the greatest
inventions of modern science. It was invented
by Charles Babbage. It is an electronic
machine. It can store a large amount of data.
The computer has made a revolution in all
fields of human activities. It is widely used in
schools, colleges, banks, hospitals, railways,
airlines, hotels and so on.
•By using a computer, even the biggest work
can be done in less time. Computer helps the
students to learn new things. Scientists and
scholars can make use of the computer in
their studies and research work. While it has
numerous benefits, it can also create health
problems if we get addicted to it. So, we
should use it wisely.

10. POWER POINT
• Microsoft PowerPoint is a presentation
program,[8] created by Robert Gaskins and Dennis
Austin[8] at a software company named Forethought,
Inc.[8] It was released on April 20, 1987,[9] initially
for Macintosh computers only.[8] Microsoft acquired
PowerPoint for about $14 million three months after it
appeared.[10] This was Microsoft's first significant
acquisition,[11] and Microsoft set up a new business unit
for PowerPoint in Silicon Valley where Forethought had
been located.[11]
• PowerPoint became a component of the Microsoft
Office suite, first offered in 1989 for Macintosh[12] and in
1990 for Windows,[13] which bundled several Microsoft
apps. Beginning with PowerPoint 4.0 (1994), PowerPoint
was integrated into Microsoft Office development, and
adopted shared common components and a converged
user interface.[14]
