'Virtual memory' is a term that is heard from the day we are born in today's society. Everything virtual is more natural to younger generations than the trees of a park or the rippling water of a shallow creek. It seems that more and more can be stored and done by virtual methods every day. But, have we reached the limits of virtual memory usage or have we simply not found the depth of the well to date?

If we are talking about the amount of virtual memory available on the average desktop computer, then the answer is both. Since we haven't yet capped the size of the personal computer in virtual memory capacity, we can't truly know if we have found the bottom of the well or not. What we can ascertain is whether each individual spigot to the well has a depth equal to the algorithm that rules the ratio of all virtual memory on a system to the amount of available and usable virtual memory on the same system.

If your system has 4GB of available virtual memory, then only 3GB can be accessed and used. The additional 1GB is used for operational resources that allow you to run all those applications that are using the available virtual memory. If it were available, there'd be no memory space for your computer to keep track of all the applications running on your computer.

Each year, personal computers grow larger as we begin to demand more space for our daily lives in the virtual realm. Many people work from home and are finding that running a business on a computer requires large amounts of virtual memory. Computer manufacturers and designers listen, increasing the much coveted space available virtually for our use.

If the trend of growth in the size of computers increases as it has been for several more years at least, then we haven't come close to the bottom of the proverbial well. We have only dipped a few buckets and withdrawn a sampler of what's available. With this in mind, our current limitations won't be the same as our future limitations.

If you do try to run more than your computer will handle, your computer will complain with a warning that it can't run the requested application because it is out of memory. At this point, you can shut down applications you may not be working on and then run the desired application, or you can invest in some memory upgrades. Keep in mind that not all systems are capable of being upgraded easily, as is the case of the laptop computers. If you are forever finding yourself out of memory, it may be best to cut back on how many applications you run simultaneously.

Technology will keep increasing our available virtual memory, but for now there is a limit in the infinite world of virtual memory upon our desktops and laptops. Perhaps in ten years, that limit will no longer exist. However, maybe we already have plenty of virtual memory since more memory only indicates more work, more hours spent producing, and less living.

AIO stands for "all in one" and MFP stands for multifunction printer/peripheral/product.
But what is difference between these two. Don't suppose to do same task. In fact they do same thing but in different scale and quality. AIO is small desktop used for home, the larger one is used for small office/home office (SOHO). But the MFP is used for large office desktop with additional parts and features.

The idea of AIO (all in one printer) or MFP (multifunction printer) came from the twenty first century people who don't bother to move because they don't have time and space for that. Therefore internet and easier compact, remote control technology created besides working from home to replicate the office environment in residential place.

How come all in one multifunction printer become so popular. Because it handles the issue of taking up all the office space with all sort of machines. In fact its combination of all regular office needs in one device. Multifunction printer can be offered in diverse functionalities and features depend on demands.

Before invention of all in one multifunction printer, it was vital to have all of different functionality devices separately and was such a mess to configure and place them. But now you just sit and by pushing the button, do all send and receive documents process like a piece of cake.

What are these Features and Fuctionalities?

• Printer: The major part that holds the name "all in one multifunction printer". It can be offered in various models like laser printer or inkjet printers. Also depends on type of usage can be designed in multiple paper feed size and type.
• Fax: fax or facsimile is a telecommunication for sending and receiving documents through telephone lines. MFP devices include this functionality which raises its capability.
• Scanner: Turning paper to electronic documents capability is another feature of all in one multifunction printer.
• Copy: Many times people need to copy a piece of paper which is for personal use at tax period or when sending out an office memo to all coworkers, copying is an essential piece of office equipment that is included in multifunction printers.

AIO for home users usually is not networked and connected with USB or parallel. Sometimes they have wonderful features which is lacking in larger desktops like smart card readers or connection to digital cameras. The SOHO the small home office size are usually networked and connected with USB and parallel. They may include document storage additional to print, fax, copy, scanner features.

Office MFP units are usually full featured. They beside the basic functions like printer, fax, scanner, copy may have advanced features like duplexing, stapling, holepunching, offset modes and booklet creation. They always networked and connected with USB or parallel.

At last Production Printing MFP are large freestanding expensive units which don't include advanced networking features like the smaller version but instead concentrate on functionalities like high speed, high quality output, finishing includes book making with cover insertion. They often divide in two segment, light and heavy printing production which factor of speed differentiate them. By the way, all multifunction peripherals divide by factor of speed (pages per minute=PPM) into different segments.
