OPERATING SYSTEM

OPARETING SYSTEM

OS	Developer	Date of Release
mac OS	Apple	2001
Android	Google	2008 – present
MS-DOS	Microsoft	1981
Windows 1.0	Microsoft	November 1985
Windows 2.03	Microsoft	December 1987

Unix	Bell Labs	1969

Types of OS

There are many types of OS available for the users. Some of these are as follows:

1. Batch OS: In a batch OS the users don’t feed the input directly into the computer. In other words, the users don’t directly interact with the OS. They upload their data onto an offline device like a punch card and then this device interacts with the OS. This is one of the most primitive kinds of the OS.
2. Single User OS: These operating systems are intended to be used on a personal computer. That is an OS that is designed in a way that it can handle one computer or one user only is known as the single user OS>
3. Multiple User OS: This kind of OS is used to control many devices at the same time. It has man terminals or points from where different users can interact with it at a given time.
4. GUI based: GUI means the Graphics User Interface based. In these OS, the user interacts with the OS through a graphical interface that can be understood easily. Examples are the Windows, Mac and Android OS.

   Booting

   When a computer starts, the OS has to be loaded first because it has to control all the other functions of hardware and software of the computer. This process is called booting. During booting the OS loads all the hardware and software applications that are preinstalled in the memory of the computer.

   Now let us see some questions that may be asked in this section of computer awareness.

   Q 1: _________________ allocates memory and other resources in a computer.

   A) CPU                B) ALU                  C) OS                      D) RAM

   Answer: If you read what was written above, you wouldn’t hesitate to answer this question as C) Operating System.

   Q 2: Pick the odd word out of the following:

   A) DOS             B) OS          C) S          D) Mac

   Answer: DOS, Mac, and OS represent the same thing. Thus the correct option here is C) S.

FAQ on Algebra

Question– Who is the father of algebra?

Answer– The father of Algebra is Muhammad ibn Musa al-Khwarizmi. He was Muslim mathematician in the 9^th century as well as an astronomer. This title was derived from the name of a book he wrote which was Kitab Al-Jabr.

Question– What is the use of algebra?

Answer– Algebra has many uses, it comes in use in our day to day lives as well. We make use of algebra in order to find the distance, volume, and perimeter of an area, determine any object’s cost, rent something, time relationships, and more.

Question– How many types of algebra are there?

Answer– There are five major types of algebraic equations. We distinguish them by the position of variables, kinds of operators and functions in use plus the behaviour of the graphs. Every equation includes a distinct probable input and creates a result with a different analysis.

Question– Why was Algebra invented?

Answer– The Greeks formed a geometric algebra. In here, they use sides of geometric objects, mainly lines consisting of associated letters in order to represent the terms. Thus, through this new kind of algebra, they made it possible to find out solutions to equations by making use of this same process which they referred to as ‘the application of areas
