What is Used by older motherboards and expansion cards and a few newer ones?

A motherboard has expansion slots, most boards even new ones will have a pci, pci-e 1.0, slots. Depending on how old the motherboard is it will not work well with todays software. The expansion slots today are mostly used for:

- Adding or replacing a video card if the orginial video port goes bad or not detailed enough (pixals in the image) to work with certain software.

- Adding USB ports if the if the older computer does not have enough or any. This way more modern perpherals (printers, keyboards, mouses, external hard-drives...etc.) can be used.

- Adding or replacing a network card.

Now take the newest boards, they have pci-e 2.0 16x, which are the fastest slots, but they still have a pci slot for say a wireless card.

Many of the connections for video, sound, keyboard, printer and anything else used on the computer is connected some way or another all built into the motherboard most times. Sometimes these connections go bad. Rather than buy another motherboard the expansion slots offers and alternative and possible upgrade to the repair of the problem.

Why the computer start with 8 bit?

It didn't, early computers had a very wide range of word and character sizes many machines were decimal so their word/character sizes were defined in decimal digits not binary bits. Even microprocessors the first commercial microprocessor the Intel 4004 was a 4 bit not 8 bit machine. The 8 bit byte as a standard only originated in 1964 with the IBM System/360.

Some examples of different computers of the past:

  • ABC: 50 bit binary words; no characters.
  • ENIAC: 10 digit decimal words; no characters.
  • IAS: 40 bit binary words; no characters.
  • UNIVAC 1: 12 character/digit decimal words; 1 digit characters.
  • IBM 701: 36/18 bit binary words; 6 bit characters.
  • IBM 702: variable length character/digit words; 1 digit (6 bit) characters.
  • UNIVAC 1101: 36 bit binary words; 6 bit characters.
  • IBM 650: 10 digit decimal words; 2 digit characters.
  • IBM 704: 36 bit binary words; 6 bit characters.
  • UNIVAC 1103: 36 bit binary words; 6 bit characters.
  • IBM 705: variable length character/digit words; 1 digit (6 bit) characters.
  • IBM 709: 36 bit binary words; 6 bit characters.
  • IBM 7090: 36 bit binary words; 6 bit characters.
  • IBM 1620: variable length decimal words; 2 digit characters.
  • IBM 1401: variable length character/digit words; 1 digit (6 bit) characters.
  • DEC PDP-1: 18 bit binary words; 6 bit characters.
  • IBM 7030: 64 bit binary words, variable length character/byte strings; variable length (4 to 8 bits) characters/bytes.
  • CDC 6600: 60 bit binary words; 6 bit characters.
  • DEC PDP-8: 12 bit binary words; 6 or 8 bit characters.
  • IBM System/360: 32 bit binary words, variable (up to 32 digits) length decimal words; 8 bit characters/bytes.
  • DEC PDP-10: 36 bit binary words; variable length (1 to 36 bits) characters.
  • UNIVAC 1110: 36 bit binary words; 6 or 9 bit characters/bytes.
  • etc.

At what store can you buy the Mini ITX Motherboard for the lowest retail price?

How do you update your USB Root Hub on your Dell Desktop?

Sometimes you can download updates off the internet, others you can get disks from your neighborhood electronic or comp. store

Why is the function key on your laptop stuck?

One reason the Fn key may appear stuck is if you recently plugged a full-size keyboard into your laptop and pressed the NumLock key. This key activates the Fn key on the laptop. To return the Fn key to its original state, plug in the keyboard and disengage the NumLock key. Remove the keyboard and test out any of the Fn assigned keys. They should return to normal working status. If it doesn't however, you may require further troubleshooting.

You can find out if its the numlock by holding the fn key to type normally. if it types normally then and oposite when released then that's the problem. you can turn it off by holding the fn key and presing either the blue "num <arrow down>" or the blue numlock key. (both are numlock just look different on some laptops.

What is EDP?

It can mean many things. It can mean electronic data processing. In law enforcement, it could mean an emotionally disturbed person.

It could also be short for Energias de Portugal (formerly known as "Electricidade de Portugal"). It ranks among Europe's major electricity operators, and is one of Portugal's largest business groups.

CD drive access is unavailable in your system How can you view a CD?

One method of viewing CDs on a system with no CD drive access is to create data images of the CDs. These images can them be mounted from the hard disk using virtual CD-ROM software.

How can you transfer files from an old Toshiba Satellite T2130CS to a PC if it will not recognize an ethernet card and does not have a disk drive?

I use a parallel port Zip Drive...

If your computer doesn't have a network card you can still move your data or files utilizing your serial port. You will need software to do this but it is very simple. There is a software bumble called PC Re locater and is available at STAPLES for about $15 this includes the software that you will need and even comes with a cat5 cable and a file transfer cable or serial cable. The software is awesome it does everything for you. You just basically tell the software what file you want to transfer over to your PC and it does the work for you. It' that simple. Take the hard drive out of the laptop and connect it to the other computer. You will need to get a converter device so you can plug the 2.5" drive into the ribbon cable designed for 3.5" drives. Or you can get USB drive en closers made to hold the smaller drives that you can simply plug into the USB port of the computer.

How do you make a message appear on another computer?

Going from some versions of Windows to Windows, you can enable the Messenger service and use the command "net send" from the command prompt.

The syntax is NET SEND {name | * | /DOMAIN[:name] | /USERS} message

For example, "net send computer01 Don't forget that meeting at 5:00 PM today"

There may also be other third party programs to do this, but you will more than likely need to install the program on both computers.

What is multiple processor organization?

A multiprocessor organization for supporting relational data base management systems is presented. DIRECT has a MIMD (multiple instruction stream, multiple data stream) architecture. It can simultaneously support both intra-query and inter-query concurrency. The number of processors assigned to a query is dynamically determined by the priority of the query and the size of the relations it references. The size of a relation is not limited to that of the associative memory as in some previous data base machines. Concurrent updates are controlled through address translation tables which are maintained by a controlling processor. DIRECT is being implemented using LSI-11/03 microprocessors and CCD memories which are searched in an associative manner. A novel cross-point switch is used to connect the LSI-11 processors to the CCD memories. While cross-point switches have proven too expensive for use in general purpose parallel processors, their application in DIRECT demonstrates that these switches can be successfully used in specialized applications.

Picture of a USB port?

USB Stands for Universal Serial Bus, the old usb 1.0 is hardly used anymore with the usb 2.0 being used most commonly with the recent release of usb 3.0 which is much faster.

How do I buy from the walmart store in puerto vallarta a computer for a son of a friend while I am back in the USA?

Go to the closest Wal-Mart store where you are in the US and ask at the Service Counter how you pay for a computer to be picked up in the Wal-Mart in Puerto Vallarta. Find out what documents the person picking up the computer will need to present. If your friend's son needs the receipt you get as the buyer, you'll have to mail or send it to him by UPS or FedEx.

Why would you want to buy the computer in the US rather than in Puerto Vallarta?

Can't the Wal-Mart there get the computer you want?

How do you turn on Vsync on your Graphic card?

Start a game, go into the options/settings, click video, click advanced and check "Enable Vsync"

Personally I don't see why anyone would want to enable vsync, so don't do it.

Alternatively you could go into your driver and find image quality and settings and enable it in there.
