We learned what data is and what information is.
Also we learned the difference between data and information. Data is a raw
facts or unprocessed item. Data can exist in various forms such as numbers, symbols,
characters, pictures or even sound. Data does not have a meaning when it stands
on its own. Information is data that is organized and meaningful. also
information can be defined as data that has been processed into a useful fact. Learned
that the main difference between data and information is that data has no any
meaning when it stand on its own but information has the meaning. I learned six
quality of valuable information. Valuable information should have the following
qualities. First one is information should be accurate. In. it must be looked
if information is current. Third one is information should complete.
Information to be complete it does not have to miss anything. Fourth one is
information should be organized.it should be well arranged. Fifth information
should be verifiable. Last quality is information should be useful.
Information plays several roles. The following
are three roles of information we have learned. Firstly, information is used in
decision making. For instance, Managers of organizations collect information
from various sources and they use information which has been collected to make
decisions. Secondly, information is used to influence and persuade. For
example, Information is used in advertisement to persuade customers to buy commodities.
Lastly, information can be a capital resource.
We learned to basic elements of information known
as reach and richness. Reach can be defined as the number of people either at
home or at work exchanging that information. Richness can be defines as amount
of quality information shared in transaction. There are three components of
richness. Those components are Bandwidth, customization and interactivity.
Bandwidth is amount of information that can be moved from sender to receiver in
a given time. Customization is when information is tailored an audience of
particular size. Interactivity is the extent to which involved parties can
converse.
I learned what computer network is. Computer
network is simply a group of interconnected computer that are connected via
hardware and software and able to communicate with each other. Also i learned
that how do computer represent data. Bit is used in computer to represent data.
Bit is the most basic unit if information in a computer. Bit uses only two
digit to represent data which are 0 and 1. We learned five basic operations
which a computer can perform. Those operations are input, output, processing,
storage and communication. Three element must exist during data communication
in a computer are sender, medium and receiver. People can use computer network
for resource sharing. For instance one printer can be shared by more than one user.
Computer network can be used for information sharing and promote communication
and collaboration. For example users can communicate with each other by sending
an email from one computer to another.
Input is any data or instruction entered into a
memory of a computer. a good example of input is password. Also we learned what
an input device is. Input device is any hardware component that allows users to
enter data and instruction into a computer. Examples of inputs devices are
mouse, scanner, keyboard, light pen and other else.
Input devices
Also we learned that output is the data that has been processed into a useful form. Output device is any type of hardware components that convey information to one or more people. Examples of output devices are monitor,printer, speaker and all display devices such as television.
