Introduction to Information Technology

This presentation provides an introduction to information technology, covering the classification of computers into supercomputers, mainframe computers, mini computers, and micro computers. It also discusses the significance of the internet, including electronic communication, online shopping, and the usage of ICT via social media. Examples are provided to illustrate the concepts.

Technology

Classification of Computers
Electronic devices that are being utilised for storing as well as processing
of data in a binary form as per instructions that are being given is
referred to as computer. They differ from one other with respect to
processing abilities possessed by them. They are classified as:
Super Computer
Mainframe Computer
Mini Computer
Micro Computer

Super Computer
They are fastest as well as largest systems that possess word length
about 64-96. They comprise of multiple CPUs which carry out their
operations in parallel and are being utilised for massive processing
as well as solve sophisticated issues. They are being used in
biomedical research, weather forecast, automobile designing, etc.

Mainframe Computer
They are less powerful as compared to super computers and their word
length can be 64, 60 or 48 bits. This involves high processing speeds
as well as have the ability for storing large data. They are utilised in
banks, airline reservations, large firms, etc.

Mini Computer
Mini Computer: These computers are not as powerful as mentioned
above two. It comprises of 32 bit word length and are liable for
performing complicated tasks. They are large in size but their
storage capacity lies in between small and medium. Such computers
are being utilised within accounting, payroll, scientific computation,
etc.

Micro Computer
They denotes personal computers as well as utilise microprocessors as
their CPU. They are small in size as well as do not possess large
storage space and their word length range is in between 8 to 32 bits.
They are being utilised for general purposes such as graphic
designing, industrial control, calculations, etc.

Internet & its significance
Interconnected network (Internet) refers to global system which is
interconnected with networks via the usage of TCP/IP for linking
the devices around the world. This was given by ARPA (Advanced
Research Projects Agency) of United States. It aims at creation of
network which must allow user of one university to communicate
with users of other university.

Cont..
Electronic communication: By the introduction of internet,
interaction has become easier as messages can be transmitted as
well as received through different mediums like emails or on social
media. This aids both individuals and business to communicate
with others and also makes things easier. Along with this, through
video conferencing meetings can also be carried out.

Cont..
Online shopping: E-commerce is driving the market which denotes that it is crucial
for firms to opt for this as each individual needs to have services at their doorstep.
With respect to individuals, it also provides easiness as well as save lots of time.
Online banking: It denotes electronic payment system which enable customers to
conduct financial transactions via their website.

Usage of ICT via Social Media
Technology is evolving rapidly with respect to all the perspectives, this
has led to creation of interface by which operations can be carried
out in an amplified manner. Information and communication
technology (ICT) is being utilised for handling broadcast media,
telecommunication, network based control, intelligent building
system as well as monitoring functions. Social Media plays crucial
role the ways in which businesses and individuals carry out their
businesses.

Cont..
Better customer services: Social media has led to open the door
through which quick connection and communication can be carried
out even when customers do not want to communicate with firm
directly. Through this, they can have their feedback and
acknowledge them respectively.

Cont..
Enhanced transparency: Social media has formulated an
environment in which problems related with communication have
been mostly resolved. The concept of transparency can be
understood by taking an instance like if customer has made any
negative feedback with respect to services that are being delivered
by firm then same problem might be noticed by other customers
also. This has led to creation of transparent environment.

Examples
For carrying out marketing of products and services that are being
offered by firm, social media provides an interface through which
ample number of customers can acknowledge what is being offered.
Suppose, Thomas Cook has brought in a holiday package for 3 days,
then social media will provide them a way to advertise their offers to
captivate more number of customers towards their services.
