The term computer itself is taken from a foreign language
(English), namely “to compute” which has the meaning of counting, while in
Latin discussion is called “computare”. In the basic concept of a computer is
an electronic device that can perform arithmetic operations calculations. From
the description above it can be concluded, the notion of computers is an
electronic device consisting of millions of components that can cooperate and
do work automatically according to instructions given and then produce output
in the form of information.
The development of computers from
time to time experienced rapid changes and progress. In the past computers were
created only as tools to simplify calculations or easier as mathematical
calculators. But along with the development of the era that increasingly modern
computers continue to evolve into a versatile machine especially in the fields
of industry and research.And now we will compare old computer and today’s
computer.
1.
The function of computer
old computers
were used only as tools to simplify calculations or easier as arithmetic
machines (arithmetic) and were also used to crack secret codes as well as tools
for designing airplanes. While computers today are used as work aids, learning
media, online business media, even as a communication tool etc.
2. The speed of computer
In terms of
speed, computers used to take a long time because they have a very large size
and have not used a microchip. Unlike today's computers that have relatively
fast speeds. In addition, when you want to access data or access information
using today's computers it is younger than in the past.
3.
The operating system
In the era of
old computers used an operating system called MS-Dos or often called Microsoft
DiskOperatingSysem. As time went on, computers now use various operating
systems, such as Mac Os, Linux, Windows etc.
4.
Types of Data processed
In the era of
old computer, computers still used machine language (machinelanguage) in
processing data, because programming languages had not been found. Besides
machine language in ancient computers used codes 0 and 1 in a certain order.
While today's computers are the types of data that are processed using
programming languages and using high-level languages.
5.
The price of the computer
In the past when
you wanted to have a computer you have to have a lot of money, because besides
the price is expensive, the electricity voltage is also very high. Whereas for
today, when you want to have a computer, you no longer have to have so much
money. Because, the price of computers today is relatively cheap and the
electricity voltage is also lower compared to today's computers.
6.
The security of the computer
In the past times
computer security was still categorized as less secure because in the past the
computer security compilers were limited and many other compilers did not
support it. In contrast to the current security of computers is increasingly
advanced because of the components of computer security is now very supportive.
Even the major countries in the world are now using computer networks as a
state security tool.
