Which is the first operating system created in the world?
This is one of the things no one will ever know for sure. When I developed software for the IBM 704 in conjunction with a missile guidance project in 1957, I had never heard of an operating system but I eventually realized that that's what I had created. It's written up in the Annals of the History of Computing, Volume 11 (1989). I can't say that it was first, but it was early, and I don't know any older ones.
How many lines of code are in the Ubuntu operating system?
Many.
The Linux Kernel itself has 13,499,457 lines of code as of 20 October 2010.
Most of programs have hundreds to tens of thousands of lines, and there are a lot components.
It would be safe to assume that there is something like 50 to 100 million lines in total.
What happens when an application is incompatible with the operating system?
Then it doesn't work correctly.
What was the first operating system for microcomputers?
In 1974, Dr. Gary A. Kildall, while working for Intel Corporation, created CP/M as the first operating system for the new microprocessor. By 1977, CP/M had become the most popular operating system (OS) in the fledgling microcomputer (PC) industry. The largest Digital Research licensee of CP/M was a small company which had started life as Traf-0-Data, and is now known as Microsoft. In 1981, Microsoft paid Seattle Software Works for an unauthorized clone of CP/M, and Microsoft licensed this clone to IBM which marketed it as PC-DOS on the first IBM PC in 1981, and Microsoft marketed it to all other PC OEMs as MS-DOS.
List the pros and cons of Mac OS X operating system?
Pros
$30 every 2 years for a new operating system/upgrade
The software and hardware are designed to work together for optimal experience
At this time it has fewer viruses that can attack it, so it is safer then Windows for now. It is built on a Unix core which is very secure and the standard for the business world.
It looks great + ease of use
Great programs for the artistic minded (journalism, photography, moviemaking, etc..)
Great customer support from what I have heard
Programs are not married to one another, so if one locks up the whole computer doesn't lock up and the program can be restarted
Leopard's Time Machine beats Windows 7 Backup & Restore hands down
Cons
Cost - brand new PC/Laptop with software and Win7 around $500 average
The EULA agreement states that you are not allowed to install its OS on any PC. So no dual booting allowed on another non Mac system, in fact they can sue you for this since its illegal.
Windows is still the premier gaming PC, you can still run many games on Mac OS X but not all of them.
Speed wise it can be slower with 3-D rendering and graphics intensive programs even if you have the best Mac you can buy.
Win 7 Taskbar is a new and improved DockBar (it does the same thing and more)
Windows XP was used for 8 years, Microsoft charged nothing extra for the service pack upgrades during that entire 8 years, compared to the additional $30 extra Mac users had to pay every 2 years to upgrade.
Not as easy to upgrade, though more companies are starting to offer upgrade options

How do you fixmy computer its screen like everything is huge?
Open the control panel, double click on display, go to setting tab, adjust screen resolution
What are the two main operating system?
there are two main opearating system
1). System Software
2). Opplication Software
MAC OS X Leopard which it's current version is MAC OS 10.5.8, maybe 10.5.9 in the future if they ever come out with another update for Leopard.
What carries out commands for the operating system?
DOS, or MS-DOS, also known as the Command Prompt.
What is demand paging in operating system?
It is a memory managermnet concept where the operating system copies the dats from the disk space to the main memory (RAM) only when is trying to access the page. it is like we have to attempt the page again, when the page fault has occured while trying to get the data.
Can Opera be used in any operating system?
No. There are many operating systems that do not have the ability to run a version of Opera. Although Opera supports an incredible number of platforms, it doesn't come close to supporting all, or even most, of them.
What is the main objective of distributed system?
The main objective of distribution system is
- i. to minimize the duration of fault current.
- ii. to minimize the number of customers affected by the fault system.
the secondary objectives of distribution system are
- i. to eliminate the safety hazards as fast as possible
- ii. to limit the service outages
- iii. to protect the consumers apparatus
Why do people create security systems?
To stop people entering personal things sutch as relationships, friends, family buisness, although many sercurity system some people can work their way through them!
What is the importance of operating?
An operating system provides an interface between the hardware and the user. It allows us to use computers without having to know how to program them.
What is the Operating system of most video gaming console?
There is no common operating system amongst video game consoles. Each uses their own operating system developed in-house by the manufacturer.
What are 10 different types of operating systems?
windows, linux, apple, macintosh,webOS, sun micro systems,HP-UX,reactOS,syllable,menuetOS
What is the operations strategy model?
WE ARE INTERESTING IN BANKING OPERATIONS STRATEGY MODEL FOR 3 YEARS TO PUT US IN GOOD STANDING IN A HIGHLY COMPETYITIVE MARKET
Define Process With a Block diagram explain various states a process resides in?
In computing, a process is an instance of a computer program, consisting of one or more threads, that is being sequentially executed[1] by a computer system that has the ability to run several computer programs concurrently. A computer program itself is just a passive collection of instructions, while a process is the actual execution of those instructions. Several processes may be associated with the same program; for example, opening up several instances of the same program often means more than one process is being executed. In the computing world, processes are formally defined by the operating system (OS) running them and so may differ in detail from one OS to another. A single computer processor executes one or more (multiple) instructions at a time (per clock cycle), one after the other (this is a simplification; for the full story, see superscalar CPU architecture). To allow users to run several programs at once (e.g., so that processor time is not wasted waiting for input from a resource), single-processor computer systems can perform time-sharing. Time-sharing allows processes to switch between being executed and waiting (to continue) to be executed. In most cases this is done very rapidly, providing the illusion that several processes are executing 'at once'. (This is known as concurrency or multiprogramming.) Using more than one physical processor on a computer, permits true simultaneous execution of more than one stream of instructions from different processes, but time-sharing is still typically used to allow more than one process to run at a time. (Concurrency is the term generally used to refer to several independent processes sharing a single processor; simultaneously is used to refer to several processes, each with their own processor.) Different processes may share the same set of instructions in memory (to save storage), but this is not known to any one process. Each execution of the same set of instructions is known as an instance- a completely separate instantiation of the program.
What is the difference between quick restore system recovery CD and operating system CD?
I believe that a System Recovery CD is for restoring your original files and a Operating System CD is where it will completely format your PC where everything is deleted, And install the OS onto your computer.But it is a very important part of an Operating computer.
