System Internals contains Linux Kernel, and it’s subsystem specific topics.
Today in this article I will discuss the difference between a microprocessor and a microcontroller. What is a Microprocessor? A microprocessor is the main functional component of a computer. It is an electronic circuit on a small chip called an integrated chip (IC) which consists of various electronic components such as transistors, resistors, diodes, etc … Read more
ALU (Arithmetic Logic Unit) and CU(Control Unit) are two basic components of the CPU (Central Processing Unit) of a computer system. Today in this article, I will discuss what is ALU, CU their functions and key differences between them. What is ALU? ALU is an essential part of CPU which is responsible for performing all … Read more
CPU and GPU are parts of a computer system that processes user inputs and gives output accordingly. In this article, I will discuss what is CPU, GPU and the key differences between them. What is a CPU? A CPU or Central Processing Unit is the main processing unit of a computing device. It takes input … Read more
Disk partitioning is the process of dividing a disk or storage device into one or more regions and these regions are called partitions. The benefit of partitioning is that you can manage each region separately. While partitioning a disk for installing a new operating system or creating new disk volumes for storing data on your … Read more
A system call is a programmatic way in which a computer program requests a service from the kernel of the operating system on which it is executed. The service may be a hardware-related service such as accessing a hard drive or the creation and execution of new processes. It provides an interface between a process … Read more
A computer system consists of various hardware elements. The RAM and ROM are one of them. These two are different types of internal memories that have different purposes of being used in a computer. In this article, you will learn RAM and ROM and the differences between them. What is RAM The RAM or Random … Read more
The computer programs earlier were coded primarily in assembly language. Writing programs in assembly was time-consuming and also limited to the machine on which these were developed. Later high-level programming languages were developed writing code in this is more like writing it in English. This enhances the code portability and productivity of programmers. Before executing … Read more
BIOS and UEFI both are the firmware interfaces that act as an interpreter between the system’s firmware and operating system. A firmware interface initializes the hardware components while the startup of a computer system. Here we will cover BIOS, UEFI, and their limitations or features so that anyone who reads this has a basic understanding … Read more
Large storage disks usually have logical partitions. An Operating System uses a partition table to identify the start address, filesystem information, and other details of a specific logical partition. The partition table in a disk is either managed in MBR or GPT format. MBR is the legacy partition table management stuff and GPT is in … Read more
Originally the term RAID defined as “Redundant Array of Inexpensive Disks” but now it is referred to as “Redundant Array of Independent Disk”. It is a data storage virtualization technology. The idea behind this is to combine multiple physical disk drives components into a single logical storage unit or drive for data redundancy, performance improvement, … Read more
