What output devices did Donald Bitzer design?
Bitzer co-invented the Plasma Display, along with H. Gene Slottow and Robert Willson back in 1964 at the University of Illinois at Urbana-Champaign for the PLATO Computer System. The original plasma display was a bright orange monochrome screen.

c:\autoexec.bat: holds and runs other programs that are listed in the file
What is the difference between a client-server network and a peer-to-peer network?
two of them are the kinds of connecting computers for resource sharing purpose. whwn we come to the peer to peer network no more than 10 computers connectd.after connecting two or more computers in to peer to peer network we can simply ping form one to another.
What are the advantages and disadvantages of a graphics tablet?
a graphics tablet (also called a pen pad) is a computer input device. It enables a user to create images free-hand, like using a pencil and paper. This apparatus is useful for signatures, drawings, etc.
Disadvantages of graphics tablet :
- slower then paper drawing
- Can be awkward to access menus and make selections
- Larger designs (A4 for example) are expensive
- Mouse feels cheap, tricky to get the hang of
A computer uses a processor to execute instructions read from ram to move data, do some simple math operations (+,-,*,/), and jump to different instructions, depending on what the data is. A computer can move the data to the monitor, the hard drive or even out into the internet. A computer also reads data from devices, such as a hard drive, mouse, keyboard, and websites on the internet.
Is software driving the development of computer hardware?
"I know your in Conrads class, find it your self! :)"
That's kind of a jerk off response. How about you learn the difference between your and you're? You're obviously getting a poor grade in English because you lack the grammar skills of a 5th grader!
What is meant by the configuration of a personal computer?
its all about your computer hardware and software
Do you need a splitter to use a dial-up Internet connection on your phone line?
If your using a modem, it should have two RJ-11 plug holes in it. One showing a telephone symbol and the other shows the RJ-11 plug. This works as a pass through and you would not need a splitter.
Can 2 HD 6870 be hooked together via crossfireX on ASRock pro3 SE?
Yes the cards can be crossfired and the board supports it.
Are there any switches which are powered by poe?
No, there are no switches that are powerd by POE.
The POE uses one of the 4 pair in CAT cabeling so reasonably priced POE switches are slow 100Mb ps. POE switches use a LOT of power 8watts per port.
Costs are coming down now. £400 for a 24 port GB switch like Netgear GS724P. But does no-one at all do a small say 4-port switch powered by PoE, of which I could use many, to extend the number of points in our school network without rewiring.
Have just found that there are switches that are powered by PoE. Linksys SLM2005 and SLM2008 which are 5 and 8 port managed 10/100/1000 switches.
What color pin goes in what color port for headphone into your acer laptop?
the universal headphone port colour is green. it should be the same on any laptop or pc
microcomputers assign one device at a time. The channel/control units decide where the next byte can be found or stored from an external device. They are similar to how they store their data. They are different on how they operate.
Where can one read the official PCI Data Security Standards?
The official PCI Data Security Standards can be accessed through the PCI Security Standards Council website. These standards are set up in order maintain standards for data security through payment cards. These standards help to prevent and detect security incidents.
Who can build my gaming computer i have all the parts but i need someone to build it?
If you have the basic know-how, you can assemble it yourself. If not, there are tons of tutorials online.
However, if you insist on having someone assemble it for you, you can go to a local computer store and they'll charge you a fee accordingly.
It means to execute a person by beheading. This verb is based on the name of the 18th Century form of execution called a Guillitine. Now, the word can be used as a verb to describe any decapitation, such as a car accident.
How do you type letters on a laptop when they have been ripped off?
if you have windows XP go to start, accesories and it should be there.
Of course it is our money and we need to buy products be it HW or SW which are relevant for our application and give best value and less overall cost of ownership.
E.g. If you are doing a lot of processing you need a faster machine with high performance. If you have a lot of data to store but not very high performance is needed you can go with moderate specification machine but with a lot of storage. Similarly what kind if operating system is needed and application software you invest in will depend on your application and budget.

Where when did Douglas Engelbert invent the first computer mouse?
Douglas Engelbert worked at the Stanford Research Institute when he worked with Bill English to develop a mouse prototype. The prototype was developed during the 1960's, while in December 1968 a demo was released.
Describe the design characteristics of unitary modular and rack mounted plc?
Unitary PLC
Unitary PLC's are compact non adaptable systems which are connected directly to the machine or equipment they control. They are one self contained unit in which is house power systems, CPU, output and input controls and any specialised pieces of equipment needed within the system. Each unitary module will have one purpose and cannot be adapted or changed after construction.
Unitary PLC's are practical if used in an industry which rarely changes production techniques and requires only a small amount of PLC usage for singular specialised tasks.
However, if adaption maybe needed in the future this is not practical.
Plus unitary PLC's are cheaper and more compact than others.
Modular PLC
Modular PLC's are multi-adaptive systems that can be changed easily and simply. They consist of a cabinet or rail upon which a system is placed as standard. This standard system contains a power supply, CPU and input and output control. However, the PLC is not specialised like unitary PLC's it can be adapted and changed to serve different purposes or you may add more than one system so the module can be multi-functional.
Extra modules such as upgraded power supplies or CPU's and specialised modules maybe added to different sections.
These systems can be rail mounted or in cabinets for safety and security.
Modular PLC's are very practical machines in the fact they can be multi-functional and are completely adaptive and their functions can be easily changed. However, these systems are a lot larger and more expensive than unitary PLC's
Rack Mounted PLC
Rack mounted PLC's are basically compact rack mounted modular PLC'S. These are multi-adaptive and can be modified easily just as modular PLC's can be.
The main difference between these two is the rack mounted PLC is mounted on racks as seen by the diagram.
Rack mounted PLC's are the most practical of all three as they make the multi-adaptive features of the modular PLC's a lot more compact and able to fit out of the way in small places. This is ideal for industry where space can be vital.
However, there is one major impracticality which is that these are the most expensive of the three.

Where can you download Windows XP drivers for an HP Pavilion DV6000?
There were actually three variants of the HP DV6000. The link provided below is for the HP DV6000t.
Simply put, the 245BW is more recent but the 244T is better. You'll notice the 244T is more expensive. There is a reason. In addition to many more inputs, USB hub built in, etc., the 244T can pivot 90 degrees to allow a portrait view. It also uses a different type of panel, I believe, that experts seems to agree is better.
Would the average user notice the difference? I'm not sure. I've never seen them side-by-side. I just bought a 244T for $569 at newegg.com. They have the 245BW for $479. I believe for $90 difference, the 244T is probably better. The list prices for the two are much further apart.
