Let us start by introducing a simple term i.e. “sort”. We all are known to this term. Sorting means arranging the items or elements in either ascending or descending order based on the priority of the ordering relation. Sorting a bookshelf or the data elements both is time-consuming and a mundane task. Both need a … Read more
Digital electronics consists of combinational circuits and sequential circuits. Combinational circuit elements are the ones whose output depends on the present inputs and do not depend on the past inputs. Logic gates, decoder, encoder, etc. are examples of the combinational circuit element. Here, we are going to discuss two of such circuit elements. Multiplexer and … Read more
There is a lot of confusions and misinterpretations regarding the difference between relay and contactor around the industry as they are two closely related terms. Many times these two terms are used nearly interchangeably. Both of them are electrically operated switches and mainly used for control and switching of loads. Although the basic principle of … Read more
Filters are a special type of circuit that lets signals having a frequency within a specific range pass through it. The frequency range can have a lower cut-off frequency and no upper cut-off frequency or an upper cut-off frequency and no lower cut-off frequency or both upper cut-off and lower cut-off frequency. Filters can also … Read more
Memory is a storage holder. It stores the data or information temporarily or permanently. We think that memory is a physical device that is used for storing but we have another type of memory which is called virtual memory. Let us explore what is the key difference between cache memory and virtual memory. Difference between … Read more
A screwdriver is a mechanical handheld tool that can be manual or powered. It can be used for screwing and unscrewing screws. A simple screwdriver is made up of a handle and a shaft that ends in a tip. The user can put the tip of the screwdriver into the screw head before turning the … Read more
We know that a computer system is made up of several components. If you want to explore in-depth, just someday open the CPU box and see what it contains and how the components are arranged beautifully. You will come to know that each component is further divided into its subcomponent and have their particular function … Read more
Crest factor is defined as the ratio of the peak value (or maximum value) to the RMS value of a waveform. It is denoted by the capital letter ‘C’. It is also known as peak factor. The waveform can be any quantity like current, voltage, etc. Crest factor Formula $\text{Crest factor}=\frac{{A_{peak}}}{{A_{rms}}}$ where, Apeak is the … Read more
Form factor is defined as the ratio of RMS value to the average value of a waveform. The waveform can be quantity like voltage, current, etc. This parameter is generally used in the rectifiers. Form factor Formula $\text{Form factor}=\frac{{A_{rms}}}{{A_{avg}}}$ where, Arms is the rms value of the waveform Aavg is the average value of the … Read more
Fragmentation is one of the core topics of operating systems. Let us understand what it means and how it occurs. Now consider the word fragmentation. What comes to our mind as soon as we hear it? We can probably think of the process of breaking it down into pieces! Or possibly can be into smaller … Read more
