In this tutorial, we will see a comparison of a microprocessor and a microcontroller. Firstly, we will begin with introductory concepts. After that, we will go through the foremost essential differences between microprocessors and microcontrollers? In a nutshell, a microprocessor is just a combination of the Arithmetic logic unit and Control unit. Furthermore, it requires … Read more
Almost all operating system based or bare metal computing systems use schedulers to schedule processes, threads, and tasks to execute on functional units. Scheduling algorithms are used for the allocation of CPU resources to all the processes that want to execute on the CPU. Schedulers provide an efficient and time-sharing mechanism for maximum utilization of … Read more
UART Communication stands for Universal asynchronous receiver-transmitter. It is a dedicated hardware device that performs asynchronous serial communication. It provides features for the configuration of data format and transmission speeds at different baud rates. A driver circuit handles electric signaling levels between two circuits. A Universal asynchronous receiver-transmitter (UART) Communication is usually an individual component … Read more

In this guide on SPI communication, you will grasp the concepts of SPI communication protocol which is also known as Serial Peripheral Interface, is a digital communication protocol that is used to transfer data serially (one bit at a time) between two or more digital devices like microcontrollers, microprocessors, or other devices. Many analog devices … Read more
In this tutorial, we will discuss the difference between a multiprocessor and a multicomputer. A computer system that has more than two processors built inside of it for simultaneous processing of all processors is a multiprocessor. A multicomputer is built by connecting two or more processors in order to work together to solve problems. Computers … Read more
In this article, we will discuss the difference between memory and registers. Both of these increase the processor’s working speed. The processor’s speed can increase by increasing the registers in the CPU or by using registers of high bit capacity. Similarly, increasing the actual main memory of the computer can cause the CPU to process … Read more
In this article, we are going to discuss the difference between the DDR2 and DDR3 and different versions of DDR (Double Data Rate Version). The major question here is: What is DDR? It is a type of RAM (Random Access Memory). In computer systems, RAM is a temporary memory storage device. The computer requires RAM … Read more
The operating system is a very significant part of any machine as it runs it. All the computers that are general-purpose are supposed to have an operating system for accommodating other applications. The main duty of the operating system is to carry out basic functionalities. For example, when input is entered using a keyboard, it … Read more
