  Delay Time The time required for the response to reach 50% of the final value in the first time is called the delay time. Rise Time The time required for response to rising from 10% to 90% of final value, for an overdamped system and 0 to 100% for an underdamped system is called the rise time of the system. Peak Time The time required for the response to reach the 1st peak of the time response or 1st peak overshoot is called the Peak time. Maximum overshoot The difference between the peak of 1st time and steady output is called the maximum overshoot. It is defined by Settling Time (t s ) The time that is required for the response to reach and stay within the specified range (2% to 5%) of its final value is called the settling time . Steady State Error (e ss ) The difference between actual output and desired output as time't' tends to infinity is called the steady state error of the system. ...

Memory Unit Computer Architecture

  Memory Hierarchy A memory unit is an essential component in any digital computer since it is needed for storing programs and data. Typically, a memory unit can be classified into two categories: The memory unit that establishes direct communication with the CPU is called  Main Memory . The main memory is often referred to as RAM (Random Access Memory). The memory units that provide backup storage are called  Auxiliary Memory . For instance, magnetic disks and magnetic tapes are the most commonly used auxiliary memories. Apart from the basic classifications of a memory unit, the memory hierarchy consists all of the storage devices available in a computer system ranging from the slow but high-capacity auxiliary memory to relatively faster main memory. The following image illustrates the components in a typical memory hierarchy. Auxiliary Memory Auxiliary memory is known as the lowest-cost, highest-capacity and slowest-access storage in a computer system. Auxiliary memory ...
