The shell relates to the user, and the kernel is responsible for interfacing the hardware.
The shell relates to the user and to application and provides a command menu or icon interface, whereas the kernel is responsible for interfacing with the hardware.
A: Shell B: Kernel
The two main components of an operating system are the kernel and the applications. The kernel maintains basic control over the computer's hardware. The kernel contains the CPU, memory and devices. Applications include the network, the user interface and security.
System software is a broad term used to refer to any type of software that helps the computer to run its operations. System software is sometimes referred to as the operating system (OS), as it is responsible for the core operations of a computer. An OS is a collection of programs, services, and other components that enable the computer to run applications and provide a platform for users to interact with the computer. It is the most important system software and is responsible for managing the computer's resources, such as memory, storage, and the processing of instructions. An OS is typically composed of a kernel, which is the core of the OS, and other components such as device drivers, libraries, and user interfaces. The kernel is responsible for allocating system resources, such as memory and processor time, to applications and providing basic services such as device access, file management, and networking. Device drivers are responsible for providing access to peripheral devices, such as printers, modems, and scanners, and libraries are collections of routines that provide an interface between applications and the operating system. Finally, the user interface provides an interface for users to interact with the computer. In addition to the operating system, there are other types of system software that help the computer to run its operations.

Kernel And Shell
The shell relates to the user and to application and provides a command menu or icon interface, whereas the kernel is responsible for interfacing with the hardware.
There are two types of interface.. 1. User Interface 2. Application Interface
A: Shell B: Kernel
we want relay interface with 8085 and also attech the program
The Application Layer is responsible for interfacing a user network request from an application via an API (application Program Interface) with the network stack. This allows an application to not have to know anything about how to do network functionality; it can merely request the network software to do something without worrying about the details.
The two main components of an operating system are the kernel and the applications. The kernel maintains basic control over the computer's hardware. The kernel contains the CPU, memory and devices. Applications include the network, the user interface and security.
The old workhorse 8255 PPI (Programmable Peripheral Interface) is a good place to start.
the principle function of memory interfacing is to enable the microprocessor to read or write into a register of the memory chip
It means an 8 bit parallel I/O interface, as opposed to 8251 which is a serial I/O.
This interface is easy to use and to learn. Some disadvantages would be that it does not have all of the features that you may want.
