Everyday advances in technology increasing merge business practices through information system support processes in varying aspect of organizations. From the dawn of the digital age, mainframes to the artificial intelligence and nanotechnology business have made use of the growth of technology through many different processes. Lower cost and increasing efficiency are two aspects that will increase the need for information system exponentially now and the years to come.

Information system process used by companies is the cluster computers system. The cluster or grid is used to reduce the amount of energy usage, cooling cost and real estate cost. The computer systems are connected virtually over the local area network. Another effect option companies use information systems is with the mobile computer.

The strengths of the cluster computer systems are higher improvement of availability for the user or client to the data. They also have redundancy node that will easily reroute if a node becomes unavailable. This system makes have many low cost, older and low power machines into a super machine by the cluster machines sharing processing power and function as a virtual single machine (Jefferson Lab 2007). With this type of information system computers balance the computational work and improve performance. One of the drawbacks of the cluster system is the fact that it can not access all the data on the cluster at once and it has very low security because all the machines share every pc on the system. The computer cluster is also a system that is not flexible because once implemented this structure has to stay in order to get the best out of it. Machines that want to be part of the cluster then leave the cluster cases issue to the collective and become a hindrance.

Today there are very few people without a mobile phone or other small digital device that has Internet access or...
