In the contemporary society, people need laptops and desktop computers
to do a variety of activities, including long distance communication, playing
music, creating databases, just to mention a few. A person can use either a
desktop computer or a laptop to execute the same program successfully. This
discussion will consider comparison and contrast between desktop and laptop
computers.
First of all, laptop computers
are suitable for mobile use while desktop computers are suitable at single
locations. Laptops differ from desktop computers in terms of design, but
achieve the same purpose of program execution.
Laptop can use alternate current when the user is far from electricity
because they have inbuilt batteries. This characteristic of laptops enables
users to operate their computers even during the event of a power outage. On
the other hand, desktop computers use direct current as the only source of power,
which means that users cannot operate them in case of a power outage.
Therefore, laptops should be portable to utilize the functionality of alternate
current.
Personal computer(PC)
are used to control trains, ships and even the planes. The use of computers
makes the itinerary more steady and safe. Since these computer systems are very
reliable, pressures of the divers can be reduced. On the other hand, computers
are used to control the traffic lights. They can accurately assign time for
pedestrians and vehicles. They contribute to our transport system. It is
believed that computer system may be out of order, and unreliable. We should
not rely on them too much. It may be true to a certain extent. However the
convenience that computer brought to us cannot be neglected. Also they rarely
become out of order. Since the convenience out weight the problems, computers
still bring us more benefits.
In
conclusion, it is apparent that both laptop and desktop computers can achieve
the same goal of executing computer programs. Both laptop and desktop computers
become functional to people. Laptop
computers have inbuilt components, while many components in desktop computers
are separate and a user must connect them to the central processing unit for
the computer to be complete and functional. Desktop computers are robust while
laptops are delicate because the screen is extremely slim.
