Operating Systems

i would say it is due to the lack of processing power, memory and storage capabilties of the handheld system in comparison to that of a PC, the Operating system will be comparable to that of older PC operating systems developed for less powerful computers.

Lots of people say that Linux is the best because it wont get so easily overloaded.

User view: 1) the user view of the computer system varies by the interface being used.

System view: 1)the operating system is a program that is most intimate with computer h/w.

User view: 2)The OS is designed for "ease of use" some attention paid to none paid resource utilization.

System view: 2)we can view an os is resource allocator. The os as act as the manager of the system.

User view: 3) Some user sit at a terminal connected to mainframe or minicomputer. User share resources & may exchange information. That is designed for resource utilization.

System view: 3)os was exist because they are reasonable way to solve the problems at creating a usable Computer system. The goal of pc is to execute user program and make solving problems easier.

Mac OS X is one of the major releases of operating systems from Apple Inc. It features a low level Mach_kernel, underlying Unix OS, a 3D graphical user interface. Mac OS X can only be installed on computers made by Apple Inc. Recent versions of Mac OS X include: Mac OS X 10.3 Panther, Mac OS X 10.4 Tiger, Mac OS X 10.5 Leopard, Mac OS X 10.6 Snow Leopard. Starting in Mac OS 10.5 an automatic backup utility called Time Machine is available.

The current version is Mac OS X 10.10 and an early release version of Mac OS X 10.11 is available to install.

1.Determine what operating system it uses. Finding out what operating system your laptop uses will let you know what key combo (such as "Ctrl+Alt+Delete") can exit you from usage and trigger a reboot or shutdown.

2.Try and reboot using the operating system. Attempt to use the key combination that will allow you to exit from the operating system and restart the laptop. Be patient, as it may take some time if it has locked up. 3. Hold down the power button. If the operating system's answer to the rebooting will not work, find and hold down the power button of the laptop. This should cause the device to shut itself off. You'll have to press the power button again to power it back on, completing the reboot. 4. Unplug from the wall and remove the battery. If restarting via the operating system and the power button do not work, unplug the laptop from the wall outlet, and remove the battery from the laptop. This will cause it to power off immediately. 5. Allow time to reboot. Give the laptop time to cool down before you power it back on if you had to do this manually. A few seconds should do unless you have additional problems.

Windows is a graphical environment operating system.

1. Windows

2. Macintosh

3.Linux

It manages the Hardware resources

maintanes the system of files

controls input and output operations

Those may be operating systems of automated machines.

Yes, it is multi-tasking.

The two main operating systems for personal devices (i.e smartphones, tablets) is iOS (produced by Apple Co.) and Android (produced by Google).

A apple computer is a fast and good looking computer they are safer then pcs with viruses, they have amazing internet, and they have great communication applications.

A PC is a better gaming system, slower than macs, and is not as protective from viruses.

A closed operating system is that does not allow you to have root access to the file system (ex. delete files or change files related to the graphical interface or how your computer does things)An example of this type of operating would be iOS which runs on iPod touches, iPhones, Apple TV, and iPad. An open operating system is the exact opposite of a closed operating system and is how all operating systems on a computer work which includes Mac OSX, Windows 7,XP, Vista, and Linux.

Software that includes an operating system as well as utilities is called an operation system package. Two examples of this type of software system are Windows and Linux.

An operating system is a program that manages the computer hardware.It also provides basis for application programs and acts as an intermediate between the computer user and the computer hardware.

The operating system communicates to the computer hardware using the GUI program.

MS Publisher is an application software. It is a part of Office suite. It is used to design things for publishing.

A real time operating system needs to be "event driven" and have the ability to perform certain tasks in a very timely manner.

Most true real-time operating systems use interrupts to handle events as they occur, such as a time-critical input message from a serial port or a digital I/O event from some peripheral hardware.

Next, there should be some kind of prioritization, meaning that one process may be time critical, such as controlling the rods at a nuclear reactor, but other processes might be a little less critical, such as dimming the hallway lights at the reactor facility after hours.

Third, there must be a mechanism in place for "multitasking", meaning that the computer must be able to switch between multiple active processes. Some operating systems create a process "stack" for each process, and if a high priority process is to be activated to handle an event, the operating system simply switches control to the higher priority process by loading the current data from the process stack. A true real time operating system can do that in just a couple clock ticks.

single user os is that os which support only one user at a time and multi user os is that which support more than one user at the same time

Yes, the earliest computers built did not have operating systems (the idea of an operating system had not been thought of) so individual programs were loaded and run one at a time. The first computer I used (in 1973) had no operating system, programs punched on decks of cards were loaded and run one at a time.

The first microcomputers sold did not have enough memory to load an operating system. When Bill Gates wrote the original version of Microsoft BASIC for the MITS Altair 8800 the standard 8800 came with only 256 bytes of RAM and Microsoft BASIC could not run with less than 4096 bytes of RAM (it was already very expensive to expand the RAM to that size), so Microsoft BASIC was written to run without an operating system.

There are also embedded system computers that are dedicated to one purpose and usually run one preloaded program supplied by the manufacturer and do not allow other programs to be loaded. While some embedded system computers do use an operating system, it is also common for the preloaded program to be written to directly control all the hardware directly without the need for an operating system.

Draw a detailed system flowchart illustrating the steps performed by an OS as it

executes the instruction to back up a disk on a single-user computer system. Begin with

the user typing the command on the keyboard and conclude with the display of the result

on the monitor.

The difference is that competing processes in an operating system compete for resources. Cooperating processes share resources, and some even work together to complete the same task.
