Linux kernelFree Unix-like operating system kernelThe Linux kernel is a free and open-sourceUnix-likekernel that is used in many computer systems worldwide. The kernel was created by Linus Torvalds in 1991 and was soon adopted as the kernel for the GNUoperating system (OS), which was created to be a free replacement for Unix. Since the late 1990s, it has been included in many operating system distributions, many of which are called Linux.Virtual memory compressionVirtual memory compression (also referred to as RAM compression and memory compression) is a memory management technique that utilizes data compression to reduce the size or number of paging requests to and from the auxiliary storage.
Memory poolMemory pools, also called fixed-size blocks allocation, is the use of pools for memory management that allows dynamic memory allocation. Dynamic memory allocation can, and has been achieved through the use of techniques such as malloc and C++'s operator new; although established and reliable implementations, these suffer from fragmentation because of variable block sizes, it is not recommendable to use them in a real time system due to performance.
Memory pagingIn computer operating systems, memory paging is a memory management scheme that introduces a level of indirection between physical and logical addresses and allows the physical memory used by a program to be non-contiguous. This also helps avoid the problem of memory fragmentation.
Data compressionCompact encoding of digital dataIn information theory, data compression, source coding, or bit-rate reduction is the process of encoding information using fewer bits than the original representation. Any particular compression is either lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy. No information is lost in lossless compression. Lossy compression reduces bits by removing unnecessary or less important information.
Cache (computing)In computing, a cache ( KASH) is a hardware or software component that stores data so that future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation or a copy of data stored elsewhere. A cache hit occurs when the requested data can be found in a cache, while a cache miss occurs when it cannot.
Random-access memoryRandom-access memory (RAM; ) is a form of electronic computer memory that can be read and changed in any order, typically used to store working data and machine code.Page (computer memory)A page, memory page, or virtual page is a fixed-length contiguous block of virtual memory, described by a single entry in a page table. It is the smallest unit of data for memory management in an operating system that uses virtual memory. Similarly, a page frame is the smallest fixed-length contiguous block of physical memory into which memory pages are mapped by the operating system.
Central processing unitCentral computer component that executes instructionsCore i9-14900KF, a 2023 CPU made by IntelInside a central processing unit: The integrated circuit of Intel's Xeon 3060, first manufactured in 2006A central processing unit (CPU), also known as a central processor, main processor, or simply processor, is the primary processor in a given computer.Solid-state storageSolid-state storage (SSS) is non-volatile computer storage that has no moving parts; it uses only electronic circuits. This solid-state design differs from the commonly used competing technology of electromechanical magnetic storage which uses moving media coated with magnetic material. Generally, SSS is much faster but more expensive per unit of storage. SSS devices typically use flash memory, but some use battery-backed random-access memory (RAM).
Input/outputIn computing, input/output (abbreviated I/O, i/o, or informally IO or io) is the communication between an information processing system, such as a computer, and the outside world, such as another computer system, peripherals, or a human operator. Inputs are the signals or data received by the system and outputs are the signals or data sent from it. The term can also be used as part of an action; to "perform I/O" is to perform an input or output operation.*As an Amazon Associate I earn from qualifying purchases.
