What type of computer generally runs one program at a time as fast as it can?
That doesn't sound like a type of computer, but an operating mode (and type of operating system). That operating mode would be called real mode. Real mode doesn't have any multitasking abilities that the software doesn't give it. Real mode was primarily used in MS DOS.
Who is the owner for Intel company?
American engineers Robert Noyce and Gordon Moore founded the Intel Corporation in July 1968. The company's name is derived from â??integrated electronics.â??
How you can connect several computer by networking?
Depends on which topology you are used i.e Ring, Bus, Mesh or Star. Like in Ring topology each node is connected to 2 nodes on either side and is suitable for small network. In Star topology there is a central node to which all other nodes are connected, data is transferred from source node to central hub and then to destination node. In Bus topology one long cable act as a back bone to link all the devices and is reliable from hardware point of view.

How computers communicate with other computers?
play guildwars 2 may inprove or better smash your network modem then check is it still woking. if it still work then it is improve
A computer mainly locks up when it cannot preform a task. Most the time the computer will try to terminate what is freezing it if it cannot continue running. Sometimes the computer will terminate a program that is used to run itself so that is why it occasionally crashes offline.
Does Target have good deals on desktop computers?
"In keeping with the ever advancing technology of today, Target puts much more emphasis on their stock of laptop computers than it does on desktop computers. They do carry a few, which are comparably priced, but selection is limited."
What is the difference between DimmDDR1 and DimmDDR2?
About three years ago DDR2 memory first appeared on the desktop PC scene. It would be impossible to say it burst on the scene since it was introduced with the unimpressive Intel NetBurst processors. In that market DDR2 was more like a trickle since it was mainly a curiosity for a processor that was running a distant second place to the leading AMD Athlon chips, which were still powered by DDR memory.
DDR2 finally became the universal standard last May/June when AMD switched to DDR2 on their new AM2 platform and Intel introduced Core 2 Duo, the new CPU performance leader. Core 2 Duo resided on socket 775, which also was fed by DDR2. While it sometimes seems like centuries ago, it is worth remembering that Intel Core 2 Duo regained the CPU performance crown less than a year ago, and the two years prior to that all the fastest systems used AMD Athlon 64/X2/FX processors.
We compared performance of DDR2 on the new platforms in July of last year. AM2 provided better bandwidth with DDR2, but the better AM2 bandwidth did not translate into better performance. Since Core 2 Duo was faster at the same timings, it appeared the Intel Core 2 Duo architecture was not particularly bandwidth hungry and that it made very good use of the DDR2 bandwidth that was available with the chipset memory controller.
Since last May/June DDR2 has finally turned the market, and it has made some remarkable transformations along the way. The early 5-5-5 timings at the official DDR2-800 speed have since been replaced by several high performance memories capable of 3-3-3 timings at DDR2-800. The best memory at DDR2-1066 can now operate at 4-4-3 timings, and the fastest DDR2 is now around DDR2-1266 and still getting faster.
Perhaps even more remarkable, in the last year DDR2 memory prices have dropped to half of what they once were (sometimes more), and today DDR2 is often cheaper than the DDR memory it replaced. Compared to the very expensive prices at launch and into the holiday buying season we see DDR2 is now the memory price standard in the desktop computer market.
Fast forward a year and Intel is now launching their first chipsets to support DDR3 memory. In one of the sloppiest NDA launches in recent memory we already have P35 boards for sale since early May. The official chipset introduction is scheduled for May 21st and boards are "officially" launching into the retail channel on June 4th.
We can tell you that Intel does not really have an NDA, but they have been very aggressive in holding first tier manufacturers to a May 21st performance embargo and retail distribution on June 4th. Despite that, people around the world have been able to buy P35 boards from several retailers. We have retail boards we bought on the open market, which makes the 21st NDA a moot point in our opinion. Still, we value our relationship with both Intel and the major board makers, so this will not be a full P35 launch review. You will see that coming on May 21st.
What this review does address is the performance of the new DDR3 memory that is launched with P35. The new Intel P35 chipset, known as Bearlake during development, supports either DDR2 or DDR3 memory. This presented a perfect opportunity to look at the performance of both DDR3 and DDR2 on the new P35 chipset. We were also able to compare performance to a Gold Editors' Choice Intel P965 motherboard. The results of these comparisons provided interesting results about the capabilities of the new P35 memory controller. It also answered the question of whether you should care about DDR3 in any upcoming system purchase.

What should a computer repair tool kit contain?
In a computer tool kit you can usually find nonmagnetic screwdrivers, a pair of tweezers, and sockets. It is also helpful to have an anti static wrist strap. This provides a ground for you.
What are the advantages of using duralumin?
Duralumin - is a strong, hard, lightweight alloy of aluminum, widely used in aircraft construction, discovered and patented in 1910 by Alfred Wilm, a German metallurgist; it was originally made only at Düren in Germany. The original composition has been varied for particular applications; it may contain about 3 or 4 percent copper, 1/2 to 1 percent manganese, 1/2 to 1 1/2 percent magnesium, and, in some formulations, some silicon. After heat treatment and aging, these alloys are comparable to soft steel in strength.
Duralumin alloys are relatively soft, ductile, and workable in the normal state; they may be rolled, forged, extruded, or drawn into a variety of shapes and products. Their light weight and consequent high strength per unit weight compared to steel suit them for aircraft construction. Because duralumin loses strength in welding, a special laminated sheet form called alclad is used for aircraft construction; it has thin surface layers of pure aluminum or a corrosion-resistant aluminum alloy covering the strong duralumin core.
It is used for making aircraft frames
It is used for making the frames of automobiles and speedboats
It is used for making household articles
Cryptography (or cryptology) is the practice and study of hiding information.
It is the method of taking any data, mathematically scrambling it into gibberish, yet allow for decryption back into the original data.
It is spelled cryptography.
In computer Network Cryptography means
The science and art of manipulating messages to make them secure is called cryptography.
Is a music keyboard an input or output device or both?
Generally, a MIDI instrument is an input device. It takes the musical data from the user who plays it. Playing the instrument sends input into the computer. However, depending on the instrument, such as if the instrument is standalone, it can possibly be used as an output device as well. Files stored on the computer could cause the instrument to play. So some are strictly input devices and some are I/O devices.
Is it important to keep up with technology?
It changes almost every year and it affects your job and lifestyle.

Difference between a super key and a candidate key?
Different set of attributes which are able to identify any row in the database is known as super key. And minimal super key is termed as candidate key i.e. among set of super keys one with minimum number of attributes. Primary key could be any key which is able to identify a specific row in database in a unique manner.

Identify five types of client computer?
There are 6 types of viruses. They are as follows:
1. The Boot Virus. A virus that infects the MBR record on your hard drive. If you still use floppy disks, then it can affect those as well.
2. Program viruses: These infect executable program files, such as those with extensions like .BIN, .COM, .EXE, .OVL, .DRV (driver) and .SYS (device driver).
3. Multipartite viruses: A hybrid of Boot and Program viruses. They infect program files and when the infected program is executed, these viruses infect the boot record. When you boot the computer next time the virus from the boot record loads in memory and then starts infecting other program files on disk.
4. Stealth viruses: These viruses use certain techniques to avoid detection. They may either redirect the disk head to read another sector instead of the one in which they reside or they may alter the reading of the infected file's size shown in the directory listing.
5. Polymorphic viruses: A virus that can encrypt its code in different ways so that it appears differently in each infection.
6. Macro Viruses: A macro virus is a new type of computer virus that infects the macros within a document or template. When you open a word processing or spreadsheet document, the macro virus is activated and it infects the Normal template (Normal.dot)-a general purpose file that stores default document formatting settings. Every document you open refers to the Normal template, and hence gets infected with the macro virus. Since this virus attaches itself to documents, the infection can spread if such documents are opened on other computers.
