What is the last operating system?
Operating systems are being created and improved constantly, so there is not, and will hopefully never be, a "last" operating system.
There is no such thing as a "GUI-based operating system." A GUI is just one of many method for interacting with an operating system and using it to accomplish a task. The GUI is in no way related to how an operating system works internally.
The major competitors were MS-DOS and PC-DOS; Microsoft and IBM. There also was an AppleDOS on early Apples; so there were at least 3 DOS'.
In advance operating system what is process synchronization?
In computer science, especially parallel computing, synchronization means the coordination of simultaneous threads or processes to complete a task in order to get correct runtime order and avoid unexpected race conditions. There are many types of synchronization: * barrier * lock/semaphore * non-blocking synchronization * synchronous communication operations advantages of synchronous communications are * no need of start and stop bits * higher data rates possible * the actual data length need not be fixed
What is the function of process control block?
A process in an operating system is represented by a data structure known as a process control block (PCB) or process descriptor. The PCB contains important information about the specific process including
- The current state of the process i.e., whether it is ready, running, waiting, or whatever.
- Unique identification of the process in order to track "which is which" information.
- A pointer to parent process.
- Similarly, a pointer to child process (if it exists).
- The priority of process (a part of CPU scheduling information).
- Pointers to locate memory of processes.
- A register save area.
- The processor it is running on.
The PCB is a certain store that allows the operating systems to locate key information about a process. Thus, the PCB is the data structure that defines a process to the operating systems.
What operating systems are supported by CimTrak?
CimTrak is supported on multiple Windows, Linux, Unix, and Macintosh operating systems
How operating system manage memory?
The memory is not unlimited - you may have 6GB of RAM, that is a lot but not endless.
The memory is split into segments and pages. When you need an application, not all of it is loaded into memory, just what you need. Then when you quit the application, the memory is released, allowing other applications to use the same part of RAM.
The memory management is made smart to load just the parts of the applications and libraries that you use, to make startup faster. It will also try to reduce disk I/O by writing only the parts that you modify, so a movie that you see is just "read" and not "written". The disk is after-all very slow compared to memory, so it will try to minimize the work here, and also fetch parts that it is pretty certain that you will use - like loading ahead when you stream a movie.
How many operating systems can you install on one computer?
There's no hard limit on the number of operating systems you can install. The limit will be dictated by the number of operating systems that support your hardware and the amount of space on your hard drive(s).
It's whats known as a "file extension" File extensions are the last three/four letters after the dot of a file name, and it defines what program is used to open the file.
Files ending with .mp3, usually open with Windows Media Player. Files ending with .doc, can be opened with MS Word. Some extensions are proprietary, such as the .pdf extension which can only be opened by Adobe Reader.
What is difference between dos and nos?
Network Operating system, NOS, is software allows the system to connect to a network. Disk Operating System, DOS, is software that uses the information that is stored on a disk.
What are the hardware and software requirements of operating system ms dos?
MS-DOS was initially released in 1981 for the Intel 8086 and 8088 based processors. There are no software requirements for MS-DOS as it is a stand-alone operating system. MS-DOS is compatible with x86 systems.
What are the file management function of the operating system under copy?
Most modern operating systems are not directly responsible for file management functions. Instead the operating system calls one of possibly several file management systems to provide these functions. This gives much greater flexibility and the ability to exchange files on different media (e.g. FAT, NTFS, HFS+, CD/DVD/UDF ISO-13346, Files-11).
What is the CD that contains a few system files that will start a computer?
Perhaps a "system start disk".
Different development teams have different focus.
Once there is something that almost works (i.e. you can sell it for money or give it to someone to use) there is a great resistance to throwing it away and using something that someone else made (Not made here... syndrome).
How do you design grid operating system?

How do you find you how fast your computer operates?
You could go to a local computer work shop and ask them about it? I'm sorry I really don't know.. I only know how to figure out how fast a laptop operates.. (finding the sticker that says Intel i2/i3/i4 ect..
What does it mean when computer says there is no operating system found?
it cannot find the operating system, your hard drive is probably failing, download the diagnostic software from the manufacturer of your hard drive and burn it to a CD or DVD and boot your computer with the CD or DVD in the drive, be sure to set your bios to boot from your optical drive first (CD drive), if it fails you will need to replace it and reinstall your operating system (probably windows in your case), I suggest that you bring it to a technician if you are not too technically inclined

What is an operating systems what is its role?
An operating system (or OS) is the piece of software that allows your computer's hardware to have a software interface. Examples of operating systems include Microsoft Windows 7, Apple OS X Lion, and even Android, Linux, and iOS. Without the operating system, a computer would boot to bios and be stuck there for all eternity.
What is an example of system software?
Windows is your operating system as in "System Software". Some systems have Bluetooth enabled in them. Here Bluetooth is a system software of the computer. If you want to be clever, you could say your BIOS, or DOS or Linux.
The largest chuck of available memory that is not fragmented.
Why operating system needed in a computer?
An operating system is always needed in a computer. It is like a surface where you can install your softwares. Without it, computer hardwares like the hard disk or Random access memory etc can not load the softwares itself.
All the operating systems work like each others. There are no major differences in these.
What is the next upgrade after Mac OS X 10.3.9?
The next version of Mac OS X after 10.3.9 is Mac OS X 10.4 "Tiger." The latest updated version of Tiger is 10.4.11.
Apple supports Mac OS X 10.4 on Macs running PowerPC G3 or higher processors with a speed of 400MHz or faster and a built-in DVD-ROM drive.
