Allocate the resources of the computer among users. The kernel is the main part of the Architecture of Unix OS.
By Priya Pedamkar. The architecture of Unix is divided into kernel, hardware, shell, files and directories in which the kernel manages the connections related to hardware, applications and commands. While the second layer is hardware and the third layer called shell is the bridge between the user, commands executed by the user and the commands in Unix that are already predefined and the last layer is files and directories which are called Unix programs mostly and can be considered as commands in Unix.
UNIX can also be called as an operating system that has its utilization in both work stations and servers. This is important for the development of the internet and the reconfiguration of computer systems. This was mainly developed for the intention to help the programmers develop software rather than non-programmers. However, now it is used by everyone because of its simplicity.
This is designed to be accessed by multiple people at a time and be multitasking and time-sharing configuration. Many of the operating systems have a simple view of how applications behave depending on their use. The application written in the operating system reads the data from disk, terminal, printer or tape and does the required processing on the other end required output is produced on to the disk, terminal, printer or tape.
Generally, operating systems are inbuilt with well-implemented facilities to support such kind of applications. As the applications, demand raises the need for more sophisticated features such as network access, inter-process communication, multitasking also increases.
These features are not documented and cannot be understood easily. The main thing is these are callable only from assembly level language.
