Concepts is Loop Mesh Node Branch Today we will see the concept of loop mesh node and a branch in the electrical circuit. So these are the basic circuit terminologies, which are quite often using the electrical circuit. So let us start with the branch in the electrical circuit. So branch in the electrical circuit is a single circuit element. Now this single circuit element could be a passive components like resistor capacitor or inductor, or it could be elements, Laker or dead sorcerer current source. So now let's find the Brontes in the given circuit. So if you see this circuit This circuit contains the five circuit elements. This circuit contains a three resistors center, two wilted sources. What is DDR and SDRAM What is RAM What is DRAM What is Cache Memory So we can say that this circuit contains five branches as each branch represents a single circuit element. So we can say that this circuit contains five number of branches.  Now let's see the concept of noting the electri...

What is Cache Memory and Function So in this Artical we'll understand what is cache memory in computers and laptops. So in this Artical, we'll see what is the importance of this cache memory?  What is the typical size of this cache memory ? what are the different levels of cache memory that we fight inside the computers? So before we understand this case, from where it let us see different kinds of memory that we see inside our computers . So the first kind of memory that we find inside our computers is the non-volatile kind of memory like a hard Disk drive . So this hard disk low contains a mechanically rotating fast disks, which is also known as platters. And if you see any, commercially-available hard disk drive, the typical rotation speed of hard disk is either 5,400 or 7,200 RPM. So as hard disk drive contains a mechanical rotating part. So in terms of the speed, they are quite slow. So the typical reader writes speed that you get with this hard disk drive is in the rang...

What is DRAM Hello friends, during this Artical, we will discuss about DRAM it's working mechanism, types and obligation do them is a type of DRAM. So let's get started. This do dumb. DDA stands for dynamic random access memory. It uses a capacitor and a transistor for storing the data as charges. It is relatively unstable. You do the judge leakers property, which means data continues to move in and out of the memory. As long as the public is available, hence it needs refreshing. Therefore electricity should always flow to the chip to keep refreshing the memory. It has to be refreshed approximately after every 15 milliseconds, it also loses jaws each time that is red. The capacitor also has to be recharged whenever it is read from because reading from the capacitor discharge is it. If the capacitor is not refreshed, it will lose its electrical charge. All Software Programs Types of Software What is DDR and SDRAM What is RAM And the cell will have a value of zero. The DRAM cell ...

What is What is Random Access Memory (RAM) Random access memory (RAM) has two defining traits. First, you can jump around in the memory space using addresses.  You can write new data up here at address 1,000,024, and then you can send a new address command and immediately read what is down here and address 88. You can also pick any starting address and then read or write sequentially from that point stop when you want and jump to a different spot and do it again. The second trait of random access is that writing new data into a certain address can be done just as quickly as reading the data from that address.  In other words, from the microprocessor or microcontrollers perspective, the timing to erase and overwrite is the same as the timing to just read the data at any address, we call this trait symmetrical read and write in NAND and nor flash memories, E prompts, which are not random access memories. The physics of erasing and writing over the last content can take lots of t...

What is DDR and SDRAM Lets us see what is a DDR and SDRAM These days, the DDR, SDRAM are used as main memories in parcel computers, such as laptops and desktops. The DDR, SDRAM is basically a dynamic random access memory. The normal dynamic random access memories are DRAM are not regulated by any external clocks. The DRAM are, I think they're lost memories. If you can have these, I think are less DRAM with the microprocessor. The computers may not work properly. The processor performs operations based on a reference. Hence the memories that are connected with the processor must be synchronous. In the year 1993, that diagrams are made synchronous and synchronous dynamic SDRAM. He has to be around, or however that transfers the data Wally on one edge of the clock, let us consider a difference clock having poor clock cycles. And this is a faster clock cycle. Second clock cycle, third cycle and photo cycle in the conventional RAM.  What is Operating System All Software Programs Types...

1. Define Software and Software Programe Let's define software. Software is all the programs that run a computer system. It can be classified broadly as system software and application software. An operating system O S is a set of programs for controlling and managing computer hardware and software. Control programs, managed computer hardware and resources by performing the following functions, job management control and prioritize tasks performed on the CPU.  Resource allocation manages computer resources, such as storage and memory data management control data integrity by generating check sums to verify the data has not been corrupted or changed communication controls and transfers data on parts of a computer system, such as communication between the CPU and IO devices, software. where a personal computer can perform a variety of tasks by using application software, which can be commercial software or software developed in house. You're probably most familiar with word proce...

In this Artical, we are going to discuss about system software, the system software access and interface between the computer, the hardware parts of the computer and the user user like you and me now, why this interface is required because we speak in language called English, or you could be speaking some other language, but the machine understands. The computer understands only one language, which is the binary language, zeros and ones. Now, if I'm speaking in English and the computer does not understand English. what is to be done and interpreter is required and interface as required the system software access such an interface, it converts all our instructions. The instructions that we are giving an English and to a machine understandable form for this work, there are different types of systems, softwares, operating system, language, processors, and device drivers.  1. Operating system.  Let's see what these softwares do. Operating system. It is responsible for functioning...
