Characteristics of big data
VOLUME
VARIETY
VELOCITY
VALUE
There are many different uses for big data but we will look at three, namely:c
Customer profiling
Advanced patient care:
agricultural sector
Mpeg4
Moving Pictures Expert Group version 4
JPEG
Joint Photographic Experts Group
Mpeg2
MPEG-2 is used in Digital Video Broadcast

STATIC WEBSITES
Static websites are websites where the information is coded directly into the
website using HTML. Which means thye onfomation will not change, unless someone changes the HTML
STATIC WEBSITES
ADVANTAGES
● Easy to host and develop.
● Affordable to host and develop.
● Can display multimedia.
STATIC WEBSITES
DISADVANTAGES
● Changes affecting multiple pages (such as to the header and footer) need to be
made on each page.
● Need to be a web developer to add content.
● Information updates less frequently.
● Need to code a separate web page file for each page of your website.
● Website is not interactive.
● Changes are time consuming to make.
One-time pin
(A&D)
AD
it is tempary
convenient
DIS
Could be out of sync
If OTP device is lost it can lock you out due to multiple attempts to login
HTTP
(Hypertext Transfer Protocol)
DYNAMIC WEBSITES
ADVANTAGES
● Changes to the template can be made once and immediately affect all pages.
● Can be updated without programming knowledge.
● Scripts can be used to update the website to only show the most relevant information.
● Can interact with the user.
● Since the content is dynamic, users are more likely to revisit the site to read the new content.
● Can display multimedia.
DYNAMIC WEBSITES
DISADVANTAGES
● Requires more knowledge to develop the initial website.
● Takes longer and is more expensive to develop.
● A single template mistake can affect all pages using that template.
HTTPS (Hypertext Transfer Protocol Secure)
is a secure version of HTTP in which data is
encrypted before it transferred. This type of technology is used by, for example, banks because of all
the sensitive information their clients access when doing transactions on internet banking.
Multi-factor authentication (A&D)
AD
More layers
Provides better productivity and brings a better experience
DIS
High set up cost
Devices may not contain the hardware
HTTP (Hypertext Transfer Protocol)
is the protocol that controls how web pages are sent from a
web server to a user’s web browser. It helps to transfer information like document, file, image, video
between computers over internet
Big data
● large datasets
● the category of computing strategies and technologies that are used to
handle large datasets.
ADVANTAGES OF BIG DATA
● Big data makes it possible for you to gain more complete answers because you have more
information.
● More confidence in available data—means a completely different approach to tackling problems.
Globalisation
can be defined as a process of connection, interaction and
integration among people, companies, and governments.
DISADVANTAGES OF BIG DATA
● Analysis from Big Data can be used by businesses to discriminate against consumers when they are
being analysed and assessed in greater detail.
● Companies also capture big data on consumer habits for targeted marketing. This has raised concerns
about privacy because every time you click on a website, post on social media, use a mobile app and
comment via email or to call centres, your data is collected for future use. Society have a right to their
privacy but without their knowledge or consent this right is being eroded.
● As big data increases, it exposes more of our data to potential security breaches. For example, if you have
approved a company to analyse your data, how certain are you that they will not fall prey to a cyber-attack
or that they will not sell your data. This could result in your private data being in unsafe hands.
