What Is An Operating System? Essay

That means that with the network operating system we can have lots of users all concurrently using resources on our serve.One of the most important aspects about server operating systems is the security. Workstation OS provides great security for end-users, but it's still not as tight as the security offered by the network operating systems. The reason for that is that with the network operating system were providing services to hundred or thousands of concurrent users. Therefore security is critical Workstation operating systems also provide some type of authentication by using user names and passwords which reside on local database on the local

When the user begins to interact with the computer, the software being used will send out a system call that will specify a task that a hardware component must perform in order for the software to continue functioning and send further requests,

The Operating System manages the flow of data and tells the processor what component needs to be doing. It does this my relaying one piece of information at a time but done so fast it seems it is doing it all at the same time. It does this by giving the information to the processer in computer language, so it can understand.

A computers operating system (OS) is the core of the computer and is more than just software. The OS controls the computer’s memory and processes as well as its hardware and software. It is the brain of the computer. Software applications on the other hand perform a certain task. Ex. Google Chrome provides internet and Adobe allows PDF files to be read (among other things). The OS is what makes all of these applications work successfully and accomplish whatever the application is designed to accomplish.

Operating systems are vital to the use of computers, they tell the machine what it is, what language, where the programs are, when things are stored, how to do things, the instruction codes to do everything. The system is in charge of security such as ensuring that unauthorised users do not access the system. There are many types of operating systems, a few are listed below:

Q. What is an operating system? A. Operating system works as an interpreter between computer Hardware and application. Operation system works as a user interface. Q. Types of Operating systems? A. There are two types of operating systems 1. SOS: Simple Operating System as for example- Windows 95,98, ME 2. NOS: Network Operating System as for example- Windows NT, 2000, 2003. Q. What is server? A. Server are computer that provides the services. As for Example:1. DNS Server 2. WINS Server 3. DHCP Server 4. RAS Server 5. VPN Server Q. What is RAS Server? A. RAS stands for Remote Access Server. It is basically use for mobile user in the network. This server provides the access connectivity for

Operating systems are very important to be able to run different applications on your phone or computer etc. so you can run multiple programs at the same time, it manages internal memory, it runs the input and output of attached devices like your phone or printer by transferring data. And lastly it also enables you to run more than 1 processor at the same time by dividing the program. So as you can see operating systems are very important to improve and be able to run your PC.

2. Streaming video applications where numerous people want to see the same show at same time, the information is being newly generated in real time

The operating system is the set of instructions that direct the computer to accomplish specific tasks such as document production and spreadsheet calculations.

You can download many utilities from the Internet. Examples of utilities are cp (copies a file), ls (lists information about files), ssh (securely connects to a remote computer), and df (lists information about free space on system devices such as hard disks).

Operating System is a main computer program that communicates with the hardware to help the computer run.

The operating system is an extremely crucial type of system software. It is the backbone of a computer. Without an operating system, our computers will not function properly. Operating systems are highly skilled software that includes programs with an ample amount of information. This information provided from these programs makes it easier for applications to communicate with the hardware. Linux and Windows are two operating systems that dominate in our society today. They are not only dominating in our society, but also in the business world. Windows and Linux are the two most popular

When looking at an Operating System one could often say that an Operating System is a large sum made up of small separate parts. Much like how Knuth describes computer science being the “wall of mini stones”. The Operating System, or the “OS” can be defined as “software that communicates with the hardware and allows other programs to run”. (TechTerms.com, 2012) The Operating System makes use of two modes known as User Mode and Kernel Mode in order to

And all of this runs "on top of" an os, such as Windows or Linux system.

Operating systems (OS) communicate with and work directly with many devices, including the monitor, keyboard, disk drivers, mouse, network adaptor, speakers, and so on, also known as peripherals. Some OS’s exchange information with specific hardware (chips) inside the computer that controls these devices.
