Who is the father of operating system?
Gary Arlen Kildall
Which is the first operating system?
Mainframes. The first operating system used for real work was GM-NAA I/O, produced in 1956 by General Motors’ Research division for its IBM 704. Most other early operating systems for IBM mainframes were also produced by customers.
What are the basic components of OS kernel?
The Linux kernel consists of several important parts: process management, memory management, hardware device drivers, filesystem drivers, network management, and various other bits and pieces.
What is OS in simple words?
An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs.
What is evolution of operating system?
Operating system evolution The first computers used batch operating systems, in which the computer ran batches of jobs without stop. Programs were punched into cards that were usually copied to tape for processing. When the computer finished one job, it would immediately start the next one on the tape.
What are different types of kernel?
Types of Kernel :
- Monolithic Kernel – It is one of types of kernel where all operating system services operate in kernel space.
- Micro Kernel – It is kernel types which has minimalist approach.
- Hybrid Kernel – It is the combination of both monolithic kernel and mircrokernel.
- Exo Kernel –
- Nano Kernel –
What are the three main components of most operating system?

What is the history of operating system?
The first operating system was introduced in the early 1950’s, it was called GMOS and was created by General Motors for IBM’s machine the 701. Operating systems in the 1950’s were called single-stream batch processing systems because the data was submitted in groups.
How an operating system is made?
Creation of the operating system requires a thousand lines of code. Their development is using the programming languages such as C, C#, C++, and assembly language programming. Through operating system, you can navigate through a computer while creating the storage and executing commands.
What is evaluation of operating system?
The operating system loads a set of jobs from job pool into main memory and begins to execute. During execution, the job may have to wait for some task, such as an I/O operation, to complete. In a multiprogramming system, the operating system simply switches to another job and executes.
Why do operating systems evolve?
Operating systems have evolved from slow and expensive systems to present-day technology where computing power has reached exponential speeds and relatively inexpensive costs. In the beginning, computers were manually loaded with program code to control computer functions and process code related to business logic.
What are the components of an OS?
The main components of an OS mainly include kernel, API or application program interface, user interface & file system, hardware devices and device drivers.
