Title 1: Hardware I/O and external storage, Cloud computing at OS aspects
ABSTRACT
Computer optimisation is a process which was initiated right from the invention of this
device. Information became an existing entity and very significant for those working with large
volumes of the same. Customer relationship management business is completely based on
operations like storage, transferring and managing information related with consumers and
customers. Cloud computing and strong hardware have enabled businesses to gain more control
over their operations through effective data management and customer relations. The expansion
of storage facilities from physical devices to clouds has changed the functionality of operating
systems. Hardware input and output was traditionally performed through mouse, keyboards and
printers. Currently Haptic sensors are used for the input i.e. through touch or sensitive
connection with the human body.
A great transition has taken place in the external storage capabilities of the computer with
help of internet and cloud computing. The legal and ethical issues related with privacy and
sharing of data are always considered as a point of risk for the businesses. Loss of privacy
indicates that misuse of information can take place which further leads to exploitation. Apart
from various advantages, there is a significant drawback of security threat when cloud computing
operating systems are considered. Furthermore, the control and flexibility for users is reduced as
the architecture or design infrastructure has certain limitations. It can be said that with effective
use of cloud computing technologies, customer relationship management operations can be
effectively executed.

BACKGROUND
Computers have certain components which together help in processing the inputs and
outputs provided by users. Operating systems and hardware devices are integral part of this
computer system irrespective of the mode of operation. Operating system (OS) is like an
administrator that handles hardware and software applications and also contributes to common
services associated with computers. Few years back, individuals just used to dream of having a
system which could be operated with bare hands i.e. without the use of any peripheral device
(Arora, Parashar and Transforming, 2013). Nowadays, this dream is reality. From smartphones
to desktops and every computer systems, everything is manageable by Haptic sensors.
Furthermore, the smart technology has also led to developments in the ways in which data or
information can be stored. The external devices that are prominently used include hard drives
and pen drives with different storage capabilities. Apart from these storage devices, internet
based platforms have also emerged recently. Amongst these cloud computing is the renowned
when it comes to computer based sharing of information (Jadeja and Modi, 2012).
I/O hardware or devices require human beings as the operator. They are not automated
and are completely based on manual functioning. The computer receives and interprets the
information which is fed through these devices. Modem, SD Card, USB Thumb drives, digital
cameras, etc. are some other I/O devices which enable both storage of information and effective
communication with the computerised system. The operating system is made compatible with
these devices by using device drivers (Zissis and Lekkas, 2012). These are software based
programs that have codes which enable smooth functioning of every external device that is being
in-tact with the computer. Operating system aspects of cloud computing include the
compatibility and accessibility for the users in different operational areas.
The basic models of cloud computing include three types of services i.e. SaaS, PaasS and
IaaS with expanded forms as Software as a Service, Platform as a Service and Infrastructure as a
Service. Web browsers, application development programs and languages and the resources
which are applied for build up of these services are quite important for the developer. From the
past 5-6 years, there is a sudden growth or emergence in the adaption of cloud computing aspects
by business organisations (Wei and et. al., 2014). The ease and convenience which is gained by
