Mobile systems are information systems that support users in motion. Mobile systems users access the system from any place, at any time. A mobile device is small, lightweight, power-conserving, computing device that is capable of wireless connectivity. According to Nielsen's measures of mobile device use, the younger the age group, the greater the percentage of people with mobile devices. There are many disadvantages when employee use of mobile system at work. When data is brought into employee-owned computing devices, the organization losses control over where it goes or what happens to it.Computer hardware consists of electronic components such as central processing unit CPU, dual-processor, quad-processor, main memory (Ram). CPU is the most important in computer because it is a "brain" of computer. CPUs vary in speed, function, cost.CPU works in conjunction with main memory (RAM). CPU reads data and instructions from memory, and stores results of computation in memory. Cache is the fastest computer memory, but it is also more expensive than RAM. The cache and memory storage are volatile, meaning their contents are lost when power is off. Non-volatile includes magnetic disks (Hard drive), solid-state storage (SSD), thumb drives, optical disks (CD/DVD)Non-volatile means their contents survive when power is off. New hardware can help organizations to generate revenue through Internet of Things (loT), Self-driving Cars, 3D Printing GE's (General Electronic) Industrial Internet Increase efficiencies, reduce waste, improve decision making. Greatest potential for smart devices in hospitals, power grids, railroads, and manufacturing plants. Smart buildings (Microsoft)ID problems like wasteful lighting, competing heating and cooling systems, rogue fans, etc. ID problems like wasteful lighting, competing heating and cooling systems, rogue fans, etc. Self-driving Cars: Make things easier, cheaper, safer. It also disrupts businesses because self-driving cars mean less car on the road that lead to fewer cars sold.3D Printing: it can print in not only plastic, but also metals, ceramics, foods, and biological material. It also has opportunities in aerospace. defense, automotive, entertainment, and healthcare industries. Every computer has an operating system (OS), which is a program that controls that computer's resources. Two types of application programs Native applications( thick-client application): programs that are written to run on one OS. For example Microsoft Access runs only on the Windows OS. Web applications (Thin-client application): is designed to run within a computer browser such as Firefox, Chrome, Opera
