Question 1
IS concepts and classification
IS refers to the information system that supports companies to
organize and analyze the data of users effectively. There are various kinds
of IS systems used by the companies including operations provision scheme,
transaction dispensation scheme, process control scheme, management
sustenance scheme and many more (Mohammadi, Al-Fuqaha, Sorour, &
Guizani, 2018).
Big data analytics
It is a kind of procedure used in the business communities to examine
larger and varied data sets for uncovering information like hidden patterns,
market trends, unknown correlations and consumer preference by which
companies can develop effective decisions in the business (Marjani, et al.,
2017). It is an effective technology that helps companies to evaluate and
handle larger datasets effectively and obtain appropriate information from
the gathered datasets. Using big data analytics, organizations can
accomplish organized and formless data in a reliable way.
Change data capture
It is defined as a computing technology that is capable to determine
and capture changes developed to a data server. Such kind of process is
used by the companies to identify the data that has been modified by which
effective actions can be taken utilizing the changed information.
ETL and RDBMS
The term ETL refers to the extract, transform and load that help
individual to copy data or signals from one source to another and manage
data handling issues effectively. RDBMS is described as a "rational
database management system” that has the potential to store data in
structured and effective manners (Zhang, Zhang, Li, Liu, & Fan, 2019).

Hadoop and MapReduce
Hadoop is a combination of open-source software utilized that
facilitates through a computing network for solving issues including data
handling problems and computation related concerns. On the opposite side,
MapReduce is a processing method used in computing devices to obtain
larger datasets and convert into another database effectively.
Internet of things
It is a leading information technology that has the capability to
interconnect computing devices, machines, networks and systems with each
other and provide a way to perform data transmission without needing
human-to-human interaction.
Mashup
It is mainly utilized to define a web-based system that combines
information from two or more sources to present a new service. Using such
approaches, companies can combine data from numerous sources
effectively.
Question 2
3G is an updated version of 2G that helped to manage communication
gaps and provided reliable services to the users. It is found that 3G provides
around 2 MBps data rate which is higher than 2G by which users can
transfer data from one source to another easily. On the opposite side, 4G
networks provide a 3 to 5 Mbps data rate which is high rather than previous
generations. Aigner, & Fattinger, (2019) found that 5G is the newest
message technology that provides up to 20,840 Mbps download speed to the
users. Therefore, in terms of information transmission rate 5G has larger
data transferring speed as compared to 3G and 4G technologies.
It is determined that 3G uses broad bandwidth or CDMA technology
while 4G contains unified IP and seamless control of wireless networks
