            System software incorporates several operating systems such as servers, utilities, and windowing systems. The key functions of system software include the allocation of system resources, which include input, time, memory, and output. Secondly, the system software is tasked to monitor system activities that include system performance in terms of time taken to respond and Central Processing Unit (CPU) operation, and security in terms of security code to allow multiple users access data (Puntambekar & Dhotre, 2007). Multiple users can access information only by entering the correct security codes. The last key function of system software is to manage the disk as well as the file. This is considered as the technical function of system software that enables users to save, copy, move, rename, and delete files.  

            Information belonging to an organization can help to either build or destroy its reputation, depending on how safe it is kept. That is, poor handling of information has greater ramifications than securing every bit of information rendered crucial by the organization. Therefore, storing data is crucial to an organization because data is a critical organizational asset that can be retrieved at any time for planning and decision-making (Choubey, 2013). This is because stored data is readily available and can be accessed and shared among departments within an organization for decision-making. If data is mishandled, it becomes susceptible and can easily be accessed and utilized by malicious people to harm the reputation of the organization. Additionally, stored data is readily available to clients and customers who rely on the information to make their choices as regards the choice whether to conduct business with the organization or not.

            Cloud computing has become the norm among contemporary organizations. Essentially, a number of benefits make cloud computing attractive to organizations today, based on the model’s inherent characteristics. These characteristics include its ability to create a dynamic computing platform for effective support of the flexible nature of services provided in an attempt to suit the needs and demands of users, while ensuring reliability and security of data (Stair & Reynolds, 2015). Cloud computing uses the consumption-based billing model that allows users to meet the cost up to what they used. Therefore, usage information is captured and forwarded to the user for billing through an integrated billing system. Additionally, the cloud computing model provides a self-managed system through software automation that allows the system to conduct various activities more efficiently while maintaining data integrity. According to Stair and Reynolds (2015), cloud computing provides IT service-centric approach to enable users to easily and quickly use an application or access a service without having to go through several procedures that are time wasting and rather expensive with time, unlike the traditional systems.

            Green computing has recently become the most reliable computer service in modern organizations. All leading organizations worldwide are increasingly embracing the technology in a bid to capitalize on it. As Stair and Reynolds  (2015) affirm, the main reason is manifest in the technology’s ability to minimize cost as far as energy costs are concerned and the need to remain on the forefront in ensuring sustainability in environmental protection and preservation. As such, resources are conserved for future generations while encouraging the recycling of waste products and the need for people to reduce energy consumption. Green computing means being economical and reducing pollution, which translates to the organization’s ability and willingness to conserve the environment, and hence creating a good image for the external environment. Therefore, the financial impact of green computing makes it more precious among modern organizations
