Operating Systems

Depending on your Blackberry device, you can choose the OS. To do so

1.control programs

2.sytem service programs

3.utility programs

Single-tasking allows all the resources of a system to be devoted to that single task.

all of the above

1. The major difference between the system Clipboard and Office clipboard is that the system Clipboard can retain only the most recently copy-pasted item (meaning it will replace the previous item when you copy a new one), but the Office clipboard will retain the last 24 items copied.

The traditional computer is a Desktop PC, with a monitor, keyboard and mouse. Also, some sort of internet connection.

Today, DOS is more historically important than anything.

DOS laid the foundation for the IBM PC to emerge in the PC market that at the time was still suffering from a total OS/platform/architecture war. It standardized soem technology in PCs such as the BIOS... however over the past couple of decades the BIOS has been rendered largely irrelevant to any processes on PCs for anythign beyond booting the system, and the past decade saw efforts to completely replace the BIOS with extensible firmware (UEFI).

So what makes DOS historically "important" is because it ended up allowing us to have PCs as we know them today, though only to a point. DOS's capabilities are limited without a lot of outside help, and even then DOS just can't really compare to any operating system with a genuine kernel at the core.

I would have to say that windows mobile is the best but for you apple lovers I would says iOS 4 for iPhone.

Eli Whitney (December 8, 1765 - January 8, 1825) was an American inventor best known as the inventor of the cotton gin. He is also known for creating and promoting the idea of interchangeable parts for the manufacture of firearms.
It wasn't a development as much as common sense. Parts designed for one item are used on another because it did not require any new engineering.

True

Time-sharing and multiprogramming have various differences. However, these two environments share the feature whereby several users can use the system at the same time.

The operating system is loaded into the computers internal memory (RAM) at start-up.

The operating system needs to 'reserve' chunks of memory to enable it to perform its functions swiftly and accurately. If a computer doesn't have enough RAM, the computer cannot run the operating system efficiently, often using empty hard-disk space - which slows down the computer.

Once the CPU has been allocated to a process, the process keeps the CPU until it releases the CPU either by terminating or by switching to the waiting state. In a general purpose computer system, users share the CPU and care about system responsiveness. If the system uses non-preemptive scheduling, some users may sit before the monitor for several hours without doing anything other than waiting for the set of processes in front of them in the system queue to finish. So, strictly non-preemptive scheduling is unlikely to be used in a general purpose computer system.

CLI is Command Line Interface

GUI is Graphical User Interface

CLI - You type commands into a prompt and the computer executes them.

GUI - You use a graphical interface and make selections with the mouse and the computer executes them.

CLI example: MS-DOS

GUI example: MS Windows XP

The two most commonly used operating systems are Windows XP and Windows Vista. If you consider all versions of Windows to be the same product, then the most know about operating systems are windows and mac OS X but Linux is used more than mac.So the two most used operating systems are windows and mac. Microsoft even said that Linux is more of a threat than mac.

It is the master of all the softwares, it control all other softwares for proper working.

At the very minimum, user identification and authentication systems support user information. A way to protect against fraud is to require users of a web site to log in with personal information such as a screen name and password.

Only in a very limited sense; the time of day clock ran all the time and printing could be done "in the background", but for most practical purposes no; for multi-tasking programmers had to write their own.

A single user System is a system used by a single user or we can say personal computer, thus all the resources are always available for the user to work on any

project,surfing the net,making programs using high level languages like C,C# etc.

But the limitation of a single user system is the wastage of CPU & resources ,when

the user is doing nothing on the system.

Multi-user System is intended to use the overall resources to maximum.We can say

a condition in which CPU has no idle time and always busy to execute programs so

frequently that it seems to interact with each user putting some job to do.Complexity increases with regard to multi-user systems because of resource sharing.
