Operating Leverage Operating leverage can be measured if the breakdown of fixed cost and variable cost in a company’s operating structure is known. Operating leverage is normally based upon operating income to avoid muddying the signal with financial leverage or taxes. Computing operating leverage would be easy if the proportion of fixed and variable costs could be known with certainty. Consider a stylized example: Operating leverage is computed by dividing the contribution margin (revenues

A History of Operating Systems To understand and to be prepared for the future of computer support it helps to know the history of operating systems. The operating system is the software that links the user to the computer’s hardware. Early mainframes (the predecessor of the personal computer) did not use an operating system. Programs were loaded onto the mainframe by paper punch cards‚ magnetic or paper tape. The user would start the program and wait for the program to complete‚ or crash

Explain the purpose of an operating system Process Management A multitasking operating system may give the appearance that a lot of processes are running concurrently/simultaneously‚ this is not true as only one process can be executing at any one time on a single-core CPU‚ unless on a multi-core or similar technology. Processes are often called tasks in embedded operating systems. The function of the task or process is something that takes up time‚ as opposed to memory‚ which is ’something that
Premium Operating system File system
An operating system is a set of software programs‚ which manage computer hardware in a controlled fashion. The operating system controls the file-system‚ process management‚ memory management and peripherals. Multi-user operating systems are used on large mainframe computers. A mainframe computer system has one very powerful processing unit‚ which may contain many microprocessors. Many users will all share this processing unit. They use terminals (a keyboard and a monitor) to access the mainframe
