- System Library: System libraries are special functions or programs using which application programs or system utilities accesses Kernel’s features.
- System Utility:
What is Linux and its architecture?
The architecture of a Linux System consists of the following layers − Hardware layer − Hardware consists of all peripheral devices (RAM/ HDD/ CPU etc). Kernel − It is the core component of Operating System, interacts directly with hardware, provides low level services to upper layer components.
Where Linux is used?
Linux is used as an embedded OS for a variety of applications, including household appliances, automotive entertainment systems and network file system appliances. Network OS for routers, switches, domain name system servers, home networking devices and more.
What is Linux why we use Linux?
Linux® is an open source operating system (OS). An operating system is the software that directly manages a system’s hardware and resources, like CPU, memory, and storage. The OS sits between applications and hardware and makes the connections between all of your software and the physical resources that do the work.
