BIOS, in full Basic Input/Output System, is a computer program usually stored in EPROM and used by the CPU to perform startup procedures when the computer is turned on. The two main methods are determining peripherals (keyboard, mouse, disk drives, printers, video cards, etc.).
What is OS structure?
An operating system is a construct that allows the user application programs to communicate with the system hardware. Since the operating system is a complex structure, it must be created with great care to be easily used and modified. An easy way is to make the operating system in parts.
Who still uses OS 2?
OS/2 lives on! Even today, OS/2 is widely used and lives on through OS/2-based operating systems sold and supported by vendors such as eComStation and Arca Noae. The New York Metropolitan Transportation Authority (MTA) still uses OS/2 to power New York City’s famous subway system elements.
Can OS 2 run Windows programs?
A near-full version of Windows code was originally included with OS/2 itself: Windows 3.0 in OS/2 2.0 and Windows 3.1 in OS/2 2.1. Because OS/2 only runs Windows user-mode system components, it is incompatible with Windows device drivers (VxDs) and applications that require them.
Who developed OS 2?
IBM OS/2, in full International Business Machines Operating System/2, was introduced in 1987 by IBM and the Microsoft Corporation to operate the second generation of IBM PCs, the PS/2 (Personal System/2).
What are the basic components of Linux?
Components of Linux System Kernel − The kernel is the core component of Linux. It is responsible for all major activities of this operating system. System Library − System Libraries are special functions or programs that allow application programs or system utilities to access Kernel functions.
What is the difference between Shell and Kernel?

What are the three types of operating systems?
This particular operating system type is commonly known as a standalone operating system. In this unit, we will focus on the following types of operating systems: standalone, network, and embedded.
What is a normal operating system?
The normal operating system is responsible for managing a computer’s hardware resources. The RTOS performs these tasks but is designed to run applications at a scheduled or precise time with high reliability. Real-time operating systems are also known as multitasking operating systems.
How many types of multiprocessing models are there?
There are two types of multiprocessors, one is called a shared memory multiprocessor, and the other is a distributed memory multiprocessor. In shared memory multiprocessors, all CPUs share the common memory, but in distributed memory multiprocessors, each CPU has its private memory.
