1. ICT ASSIGNMENT

3. INTERNET OF THINGS
 The Internet of Things (IoT) is a system
of interrelated computing devices,
mechanical and digital machines,
objects, animals or people that are
provided with unique identifiers (UIDs)
and the ability to transfer data over a
network without requiring human-to-
human or human-to-computer
interaction.

7. CLOUD COMPUTING
 Cloud Computing is the use of
hardware and software to deliver a
service over a network (typically the
Internet). With cloud computing, users
can access files and use applications
from any device that can access the
Internet. An example of a Cloud
Computing provider is Google's
Gmail.

9. Why cloud computing?
 Cloud computing allows consumers
and businesses to use applications
without installation and access their
personal files at any computer with
internet access. Cloud-
based services are ideal for businesses
with growing or fluctuating bandwidth
demands

10. How does it works?
 Via an Internet service
connection, cloud storage works by
enabling users access and to download
data on any chosen device, such as a
laptop, tablet
smartphone. Cloud storage users can
also edit documents simultaneously with
other users as well, making it easier to
work away from the office.

13. INTERANET

14. INTERANET
 The term Intranet is derived from two
words: ‘Intra’ which means within and
‘net’ which means group of
interconnected computers.

15.  It is a private computer network that
uses Internet protocols and network
connectivity to securely share any part
of an organization's information or
operational systems with its employees.
In short, an intranet is private network,
similar to the Internet and using the
same protocols and technology,
contained within an enterprise .

16. INTERNET
 Internet is a Global network of
computers which may be server or client
that exchanges information. It can be
defined as a "network of networks"
which can be linked through copper
wires, wireless connections, and other
technologies.

17. WWW: World Wide Web

18.  The World Wide Web is a set of all the
websites connected to the internet
worldwide. It is also known as WWW or
Web. It is a system of interlinked
hypertext documents accessed via the
internet.

20. WEB BROWSERS
 Google Chrome
 Mozilla Firefox
 Opera
 Internet Explorer
 Safari
 Netscape Navigator

21. HTTPS
 is an extension of the Hypertext Transfer
Protocol (HTTP). It is used for secure
communication over a computer
network, and is widely used on the
Internet.
 HTTPS creates a secure channel over
an insecure network. This ensures
reasonable protection
from eavesdroppers and man-in-the-
middle attacks

22. WAN & LAN
 LAN : Local Area Network, is a network
that covers a small geographical area
such as homes, offices and groups of
buildings.
 WAN : Wide Area Network, is a network
that covers larger geographical areas
which can span the globe.

24.  small geographic area (e.g. room,
office).
 controlled by one administrative
authority
 usually high speed
 always shared

25. WAN

26. WAN
 Wide area network.
 WAN covers a large geographical area.
 Crosses metropolitan, regional, or
national boundaries.
 Uses routers and public communications
links. eg. Internet.
 Used to connect LANs and other types
of networks together.

27. SIMULATION

28.  A simulation technique uses a
probability experiment to mimic a real-
life situation. It provide users with
practical feedback when designing real
world systems.

29.  A simulation technique uses a
probability experiment to mimic a real-
life situation. Instead of studying the
actual situation, which might be too
costly, too dangerous, or too time-
consuming, scientists and researchers
create a similar situation but one that is
less expensive, less dangerous, or less
time-consuming.

32. EXPERT SYSTEM
 In artificial intelligence, an expert system
is a computer system that emulates the
decision-making ability of a human
expert. Expert systems are designed to
solve complex problems by reasoning
through bodies of knowledge,
represented mainly as if–then rules
rather than through conventional
procedural code.
