" an order-processing application that requires a multiprocessing operating system " - the answer is in the requirements, a multiprocessing operating system. All modern OS's are multiprocessing, but if your store will get a decent traffic for efficiency reasons you will have to use a server OS (a Windows or Linux one, depending on the exact form of the program)

Why does my computer almost always come up with a black box say something to the effect of "Task Manager is closing background programs......" when I try to shut down?

There are many "processes" that run in order to provide services to the user and the application programs you install. I've seen system with as many as 85-100 processes running with no actual applications open. Occasionally, these processes take extra time to close down if there are other processes preventing them from doing so immediately at shutdown. To avoid corrupting the processes, the OS alerts you, the user to the extra time needed so you don't think there are any problems. You may have the option to force them closed, but unless you are willing to risk a corrupted file, doing so is not wise. Be patient and wait. This is a normal occurrence that will happen from time to time.

Mere adjustment of PC's date and time at the control panel<br />does not do the magic as most sites would tell you.......<br /><br /><br />RunAsDate is a small utility that allows you to run a program in the date and time that you specify. This utility doesn't change the current system date and time of your computer, but it only injects the date/time that you specify into the desired application.<br /><br />You can run multiple applications simultaneously, each application works with different date and time, while the real date/time of your system continues to run normally.<br /><br />Using RunAsDate<br /><br />RunAsDate doesn't require any installation process or additional DLL files. In order to start using it, simply copy the executable file (RunAsDate.exe) to any folder you like, and run it.<br /><br />In the main window of RunAsDate, select the desired date and time and the application that you want to run. Optionally, you can also specify the command-line parameters to run the program. Press the "Run" button to start the application with the specified date/time<br /><br />RunAsDate Limitations<br /><br /> RunAsDate only works on 32-bit Windows applications. You cannot use it for old DOS 16-bit programs or for 64-bit Windows applications.<br /> RunAsDate will not affect applications that take the current date/time from another source. For example: application that loads the current date from remote serve<br /><br />TO DOWNLOAD<br /><br />visit <a href=""></a>

An operating system "OS" or "DOS"

Operating Systems Means, Tips & Tools.Microsoft Windows Server 2008 is the company's latest server operating system. Officially launched in February 2008, Windows Server 2008 is the successor to Microsoft's previous server OS, Windows Server 2003.
"The other is Disk Operating System, in a general sense, DOS refers to just about any operating system. More commonly, it describes the operating system Microsoft developed in 1981 for IBM's line of personal computers. Though syntactically distinct, DOS shares similarities with a Unix shell. It has a command-line interface and analogs to many common Unix commands. However, DOS is a 16-bit, single-user operating system that does not support multi-tasking. It is far easier to administer than Unix, but less powerful. Compared to graphical interfaces such as Windows and Mac OS X, it's also not particularly user-friendly."
An operating system sometimes abbreviated as "OS".Operating System is the program that being initially loaded into the computer by a boot program or manages all the other programs in a computer. The other programs are called applications or application programs. The application programs make use of the operating system by making requests for services through a defined application program interface (API). In addition, users can interact directly with the operating system through a user interface such as a command language or a graphical user interface (GUI).
An operating system performs these services for applications:
  1. In a multitasking operating system where multiple programs can be running at the same time, the operating system determines which applications should run in what order and how much time should be allowed for each application before giving another application a turn.
  2. It manages the sharing of internal memory among multiple applications.
  3. It handles input and output to and from attached hardware devices, such as hard disks, printers, and dial-up ports.
  4. It sends messages to each application or interactive user (or to a system operator) about the status of operation and any errors that may have occurred.
  5. It can offload the management of what are called batch jobs (for example, printing) so that the initiating application is freed from this work.
  6. On computers that can provide parallel processing, an operating system can manage how to divide the program so that it runs on more than one processor at a time.
All major computer platforms (hardware and software) require and sometimes include an operating system. Linux, Windows 2000, VMS, OS/400, AIX, and z/OS are all examples of operating systems.

The most important program that runs on a computer. Every general-purpose computer must have an operating system to run other programs. Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system has even greater responsibilities and powers. It is like a traffic cop -- it makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system.
Operating systems can be classified as follows:
  • multi-user : Allows two or more users to run programs at the same time. Some operating systems permit hundreds or even thousands of concurrent users.
  • multiprocessing : Supports running a program on more than one CPU.
  • multitasking : Allows more than one program to run concurrently.
  • multithreading : Allows different parts of a single program to run concurrently.
  • real time: Responds to input instantly. General-purpose operating systems, such as DOS and UNIX, are not real-time.
  • Operating systems provide a software platform on top of which other programs, called application programs, can run. The application programs must be written to run on top of a particular operating system. Your choice of operating system, therefore, determines to a great extent the applications you can run. For PCs, the most popular operating systems are DOS, OS/2, and Windows, but others are available, such as Linux.
    As a user, you normally interact with the operating system through a set of commands. For example, the DOS operating system contains commands such as COPY and RENAME for copying files and changing the names of files, respectively. The commands are accepted and executed by a part of the operating system called the command processor or command line interpreter. Graphical user interfaces allow you to enter commands by pointing and clicking at objects that appear on the screen.

    Would like to order Printmaster 18.1, compatible with Windows 7 but as I live in Australia I am unable to order online as your orderform does not cater for sahipping to my country. I have used...

    Not compatible or not working well with windows 7?
    (make your program/application run with windows 7)

    Maybe, It doesn't work because the driver/application you installed is for other versions of operating system. I am also using windows 7 like you so don't you worry, You can still use your old installer/driver from other versions of operating systems. Just remember that before installing any program in a windows 7 Operating System Computer, Use "troubleshoot compatibility". Right Click the Icon of your program installer/application first, then choose "troubleshoot compatibility". This will allow you to choose on what type operating system your program will run. Just reply back if it still doesn't work.:D rate and vote for me:))

    Multiprocessing - An operating system capable of supporting and utilizing more than one computer processor. Multiprocessing refers to an operating situation where the simultaneous processing of programs takes place. Below are some examples of multiprocessing operating systems. This also comes with Multi Tasking and Multi user (and multi threading as well). There are SMP and ASMP systems. Read further from here It can be a system which controls a computer or any other hardware device. Examples: Unix/Linux (true support), Windows NT, Windows 2000, Windows XP Professional Windows use SMP and XP sometimes tends to give errors). Vista Business, Enterprise, or Ultimate support multi core and multi processing/processor technologies. (Same applies for Windows 7) Any Server OS such as Windows 2000, 2003, 2008 (not good for client computing. they are servers)
    You have to analyze the actual requirement here. Multi processors or multi-core/mthreading/mtask. I don't see any necessity to run a multi processor OS though. You can select a Unix version if the cost cutting applies but need to find an application which suites it. Not sure whether you could find such an advanced application according this scenario.
    RAM requirements. Depends on the OS, Workload and the Application. You can check for each OS and use recommendations. Check the application requirements and compare it with the OS. To get an idea of the work load you have to simulate a system and use compmgmt.msc and add a Performance Counter. Each application has workload data in their web sites.
    Processor requirements: Pentium which class? 4 is good 2.4GHz and upwards. Better a dual core for the scenario. No need to go for a core 2 or quad core if the cost cutting involved.
    Hard drive: Depends on the OS requirements. And the applications + storage. The number of customers will affect this very much. You have to re adjust it after examining the Application requirements.
    If you need to share the data you have to think of a storage server and file sharing as well. (If the application supports running an internal database one of your machines should hold the database or run in in a server to support multiple users. Nowadays most apps require such. But the requirement says to store data in local PCs so you can ignore it).
    Internet requirements. Analyze the required bandwidth for application in the LAN/WAN. 100mbps would be enough in most cases. Internet speed depends on the number of transactions a day. 1. Application 2. Per User. 3. Per employee. Its easier to find the app requirements. It should be available in the product sites. If not assume. (Availability, Response time, Reliability) Per user: Only if users access from the internet. Ignore otherwise (Availability, Reliability). Per Employee: Add user traffic to the findings. (Availability ,Response time, Reliability)
    Internet requirements : No clue given. Check available options in your country. ADSL 2+ would suite with 1Mbps or more. This must not be a bottleneck ( in case of a single gateway failure).
    Scalability Issues. You have to support scalability (in case of an expansion) Each app must support it. The network requirements must support it.
    Availability = Approximately Real-Time.
    Response time: Avoid bottlenecks (OS or app or network and specially no slow machines due to RAM/ Processor over utilization and HDD slowness) Sata would suite in your case (but its possible to use iSCSI since its reliable and fast).
    You need a corporate printer (if cost cutting not applied - a print server). Otherwise a shared printer. (You can use Windows work group - May differ in Unix) Fax if necessary. Its fine if all in one machine could be purchased. There are low cost solutions from HP.
    A backup database or a HDD.
    An E-mail solution. (You can utilize public platforms as well such as Yahoo - Offers more security).
    Reliability : The major factor Bottlenecks >>> 1. PC hardware (you can use the required). 2. LAN Switch and/ or Router (If and only if the network needs to be analyzed. Use a hot standby switch / router to avoid bottleneck. How ever if there is not much necessity for a Network environment you can just use an ADSL router with a switch. Switch should address scalability issues). 3. Using a backup connection such as a Modem connection for internet.
    I don't think labor requirement is an issue. A user who has capabilities to administrate the systems will be enough. 1 Person. Antivirus / File Antivirus / Firewall (a must). Recovery software if needed.
    Hope this helps to give an idea.
    Please be kind enough to rate this answer with a testimonial.

    McAfee not installing

    What you need to do is buy additional memory and install it.
    Whats happening is that the memory installed is not enough to run all the applications on your computer. In order, to properly run any more applications (programs) its the only thing you can do or remove the programs you don't need.
    Hope this helps. Bud
