As I stated earlier, I spend the first day of my information
systems class discussing exactly what the term means. Many students understand
that an information system has something to do with databases or spreadsheets.
Others mention computers and e-commerce. And they are all right, at least in
part: information systems are made up of different components that work
together to provide value to an organization. The first way I describe
information systems to students is to tell them that they are made up of five
components: hardware, software, data, people, and process. Technical Data used
in the field explained in it courses in rawalpindi .
The first three, fitting under the category technology,
are generally what most students think of when asked to define information
systems. But the last two, people and process, are really what separate the
idea of information systems from more technical fields, such as computer
science. In order to fully understand information systems, students must
understand how all of these components work together to bring value to an
organization. Some more details of it courses in Rawalpindi
are as under.
Technology
Technology can be thought of as the application of scientific
knowledge for practical purposes. From the invention of the wheel to the
harnessing of electricity for artificial lighting, technology is a part of our
lives in so many ways that we tend to take it for granted. As discussed before,
the first three components of information systems – hardware, software, and
data – all fall under the category of technology. Each of these will get its
own chapter and a much lengthier discussion, but we will take a moment here to
introduce them so we can get a full understanding of what an information system
is.
Hardware
Information systems hardware is the part of an information
system you can touch – the physical components of the technology. Computers,
keyboards, disk drives, iPads, and flash drives are all examples of information
systems hardware.
Software
Software is a set of instructions that tells the hardware
what to do. Software is not tangible – it cannot be touched. When programmers
create software programs, what they are really doing is simply typing out lists
of instructions that tell the hardware what to do. There are several categories
of software, with the two main categories being operating-system software,
which makes the hardware usable, and application software, which does something
useful. Examples of operating systems include Microsoft Windows on a personal
computer and Google’s Android on a mobile phone. Examples of application
software are Microsoft Excel and Angry Birds. TSK Training for Skills and
Knowledge is the best institute in Rawalpindi Islamabad for Pakistani Students
who wants to join it
courses in Rawalpindi.
