Prior to the commencement of the lecture, the lecturer gave us a general overview of the technological world..However, i learnt that a computer is an electronic device or a
programmable device which accepts
data,
process it and gives
output due to a set of instructions.. I learnt that the basic operations of are a computer are (a)..input
(b)..processing
(c)..output
(d)..storage
(e)..communication
Before the lecture...i used to use the terms data and information interchangeably because i was not aware that they are different...It was after the lecture that i got to know that data is just raw facts whilst information is processed data.
** I learnt that data when grouped becomes information, and when information is contexualised becomes knowledge..The computer PROCESSES data to become INFORMATION.
So the computer accepts data from input devices(any hardware devices which allows the user to enter data or even instructions into the computer). Some examples of these are scanners, mouse, keyboards.
After accepting the data, the computer processes it and gives information as the output..via output devices like monitor, printer, speaker.
In addition, i learnt that information is used for decision making, and also to influence..because in order to convince an investor ,one uses information rather than data.
Moreover, information is meant to be valuable, and in order to achieve this it must be
accurate,
verifiable,
timely,
organized,
complete and
useful. Information must be concise as well as cohesive to the subject at hand, and also the sources must also be clear thus coming to another point of
DATA INTEGRITY, which is the degree to which data is correct. Which made sense to me because one cannot create correct information from incorrect data..
*Before my esteemed lecturer came to my rescue, i wondered how people in different geographical locations communicate using computers. Thus when i got to hear of a computer network, which is a group of interconnected computers by hardware or software.
INFORMATION MANAGEMENT :
The first thing prior to the commencement of the topic, we were told to form groups to present on certain topics related to information management..It was through these group presentations that i got to know that
IM is the collection and management of information from one or more sources and the distribution of that information to one or more audiences.
)
In addition, for information management to be successful..there must be 4 key points namely
technology
people
content
process
&
if these keys are not handled professional they give rise to so many problems which tend to hinder information management...and this the part where my colleague and i presented on..We pointed that
even though the aforementioned key points are necessary for information management to be successful, most of the problems are also centralised on these key points..
-internal(office) politics
*people are meant to coordinate activities in an organisation, and one can sabotage the other simply maybe because the other person was chosen to oversee a certain department..
-cracking(commonly known as hacking)
-virus
-process
*how we manage information(paper base system/computer base system)
**information on paper is prone to damage due to wear or being torn..as one tries to get the desired file..he/she might mistakenly distort information
