Operating Systems

You can use any operation system in fourth generation computers.

An example of a multitasking operating system is the system at a school. You use many programs and do many tasks at the same time, so you are multitasking on the computer

Disk operating system DOS is a computer operating system using line instruction. For a computer system use disk drive as secondary memory. A Windows system is a computer operating system with Graphic User Interface GUI instead of line instruction.

There is no difference between them other than what the vendor or creator wants it to be. A disk operating system is a system based on being run from a disk drive. Typically disk operating systems were single user and single task systems. Predecessors to DOS used cards, magnetic or paper tape as as input, output or main storage device. Successors that relinquished the DOS title had multiprocessing, multiuser, realtime or windowing capabilities and were given other names such as OS/360, RT-11, Windows, multics, unix, linux and more.

All modern systems are disk based, unless they use solid state drives (SSD), so all are disk operating systems. Microsoft windows as well as unix, linux, OpenVMS all have a windows interface so they can all be windows operating systems but only microsoft makes that claim.

Yes.

64-bit refers to a processor with registers that store 64-bit numbers. A generalization would be to suggest that 64-bit architecture would double the amount of data a CPU can process per clock cycle. Users would note a performance increase because a 64-bit CPU can handle more memory and larger files. One of the most attractive features of 64-bit processors is the amount of memory the system can support. 64-bit architecture will allow systems to address up to 1 terabyte (1000GB) of memory

No. Many operating systems do no even have a GUI. Such systems usually use text files to change / set settings.

Among systems that have a GUI, at least optionally, there is usually a control panel or a similar menu to change settings.

Hope this is what you are looking for. My customers get very frustrated when the menu goes for a bunk so

First one is easy to solve. I've seen this happen when the menu suddenly become invisible because it has been pushed down too far. The menu is adjustable and it can be accidently adjusted.

Try this first: move your mouse to the bottom of the screen - the very bottom. Sometimes the arrow key will change to double headed cursor. This means the menu has been squished down. While the cursor has the double arrows, hold the left mouse button down and drag up slowly. Drag until you see your missing menu bar then let go.

I find just shutting the computer off, using the off button on the case and then turning it back on again normally resolves the problem if the first trick doesn't work. To turn off your computer, hold the off button in for about 10 seconds and it should power down the computer. When windows comes back up, the menu should be back to normal. I generally don't recommend people use the off bottom like this, but sometimes you can't get around it.

If these steps don't work you may have a virus or parasite (similar but not quite the same). Run a thorough virus scan and see if it catches anything. Also get a piece of software like Spybot's Search and Destroy http://www.safer-networking.org/index2.html install it and run it. It will take awhile but if anything is there, it will find and eliminate it.

Try these steps before resorting to a complete reinstallation of your OS.

Hopefully one of them will work.

I have used System Mechanic 6 when it was a newer software, I have moved on to other system maintenance software only because I enjoy trying a variety of different software. I would personally recommend System Mechanic software for any user.
