In combinational circuits, we deal with the devices whose output depends solely on the present inputs and not on the past inputs. Logic gates, encoder, decoder, multiplexer, demultiplexer are examples of such combinational logic circuit elements. Here we are going to discuss Encoder and Multiplexer. They have a few things in common such as, both … Read more
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
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
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
Depending on the type of signals used to transmit data or information, the communication system can be divided into two categories – analog communication system and digital communication system. In this article, we are going to discuss what is the difference between analog and digital communication systems. Difference between Analog and Digital Communication in tabular … Read more
The computer is an amazing creation by a human. And memory is the beauty of this creation. No doubt that computer memory is unbeatable to any creation in this universe. It is considered the brain of the computer. The information stored inside this memory is further processed as per the instructions given to the processor. … Read more
