When the term computer was invented, people used to watch
it, with a different look. But, today, computers have become
very essential part of our daily life. Today's super fast
computer can somehow dominate over even human brain !!!...
Do you know, a real fact about the super computer?... The super computer
Deep Blue created the history by winning the chess game against
Garry Kasparov, the then world champion in chess!!!...
When we speak about types of computers, based on its reliability, capacity
and physical structure, it has been divided into four major types,
during early days.
Micro computers :
Personal computers, Laptops and most common known computers are all
come under microcomputers. Microcomputers are most commonly used computers
in homes, schools, offices and etc. Rather than PC and Laptops, Tablet
PC, Smartphone’s, PDA’s, carputers, Ditto’s are
all other computers which are all known as Microcomputers.
Mainframe computers :
These computers are large expensive computers, which are mainly used
by the governmental departments or by the large organizations, where
they need to perform bulk mathematical computations or to execute
Mini computers :
This is a computer which is no longer much used and it is an intermediate
between Microcomputers and Mainframe computers. These computers are
mainly used by general business applications and by the department
level operations in the larger organizations.
Super computers :
As name indicates, supercomputers are the computers whose rate speed
will be super. Supercomputers are mainly used at the research centers
for intense numerical calculations such as weather forecasting, fluid
dynamics, nuclear simulations, theoretical astrophysics, and complex
But, today, the entire scenario got changed due to competition among
companies to bring out the latest technology systems. Every fortnight,
there will be new release of new technologies and also release of
devices which supports that technology. Today we just saw 1 TB hard
disks, but, tomorrow there will be a hard disk with a capacity of
Today’s computing world normally looks into 3 basic types of computers.
Desktop computers :
These computers are usual computer systems which consist of CPU or
System box, Keyboard, mouse, Monitor, which are kept on a desk or
on a table. These computers do have external wiring to connect required
devices to the CPU box. They use external power source from a wiring
that normally connects to the external Un-interrupted Power Supply (UPS).
Laptop computers :
These computers are systems which are easily carry able. These computers
are mostly used by business executives for presenting their product
through the computers. These computers have got separate motherboards
and memory cards meant for it only. They are of less weight, and have
LCD or LED screen for displaying purposes. The costs of the laptops
are slight higher than the desktop, because of its easy mobility.
They are also called as Note Book computers.
Netbook computers :
Very recently, it is found that, laptops do cost more unnecessarily
for a home user who uses his laptop only for net browsing only. As
a result, a less featured version of laptop was created. They are
called as “NetBook” computers. They are smaller in size
than the Laptops. Netbook components do differ from the components of a laptop. They
do have LCD or LED screens which are similar to laptop but, do smaller
in size. Processor manufacturers Intel have released Atom Processors
which are meant only for NetBooks. They do cost lesser than the laptops.
But, computer techies don’t prefer to buy a “netbook”
because, they don’t open development environments faster. Also,
the other reason is that the “Netbook” storage space is
lesser, when compared to the “Notebook” computer.
