Is Modern washing machine is an example of a Special-Purpose Computer?
In a modern washing machine, the wash, rinse and spin cycles are controlled by special purpose (embedded) computers.
What software controls the overall activity of the computer?
System software is a collection of programs and data that helps the computer carry out its basic operating tasks.
What company manufactured the supercomputer?
High performance computing has evolved in stages and there was no specific criterion that defined the first supercomputer. That said, most professionals consider Seymour Cray to be the father of the modern supercomputer. He was an engineer and designer for Control Data Corporation (CDC) computer system that dramatically enhanced computing in the 1960s and 1970s and he subsequently formed the company named Cray Research specifically to create new supercomputers.
Many people consider the CDC 6600 built in 1963 to be the first supercomputer. Whether one thinks it was or perhaps thinks a later machine should have the title, it matters little because for almost three decades, the fastest computers in the world were designed largely by Seymour Cray. This ended with his unexpected demise in 1996. His company, Cray Research, continues to be a dynamic force in high performance computing.
Why my dell computer shuts off after a while?
Your problem can be due to many reasons, maybe the power suply of your computer, maybe the power switch is not well attached to the motherboard, etc... You don't say which operating system you are running and what kind of machine you have, so let's make some more research. I supose is your personal computer and you don't have installed any kind of software to limit the access to your PC. I recommend you to perform a virus scanner looking for viruses and trojans, you can do it for free by clicking on the link to your right. Also you have to be careful with the temperature of your computer, if your computer is relatively new you can look this value in the BIOS of your PC, when the system starts press Supr (may vary from computers) and enter in the BIOS, there must be a place to look this value. Check your motherboard documentation to know where is this information and what are recommended values. For example, if you have a 7200 rpm disk without fan attached to it, this can make the temperature inside the PC case too high. "If you have a system that seems to run fine, then just shuts itself off after a half hour or so, check out the operating temperature of the CPU. See that the fans are working on the power supply and the CPU's heatsink." Probably it's because your computer has got a virus and if this is really the cause, what you can do is just reformat your computer and everything will be fine then.

Difference between IBM and Apple computers?
Without getting into a PC vs Apple debate; the main difference between an IBM (PC) and an Apple PC, is the operating system.
Apple computers run on Machintosh OSX (older apples might use an earlier OS version, such as OS9) while IBM PC's will run on Microsoft Windows operating systems, such as Windows Vista, Windows XP or the latest Windows 7.
Apple computers generally are more expensive, and at the same time offer reliability. They are generally marketted to the Arts industry, such as music creators or graphic designers where as IBM PC's are generally marketted to businesses that require a robust framework on which to run their programs - most accounting software for example will only run on a Microsoft based operating system.
Microsoft based computers are generally known for their value for money, whilst comprimising quality, where as Apple computer's are generally overpriced, but providing a much better user experience.
There isn't alot of difference nowaday's anyway -- Mac's are coming down in price, and window's usability is skyrocketting with the release of Windows 7.
When was Journal of Computational Acoustics created?
Journal of Computational Acoustics was created in 1993.
Are computer viruses man made or naturally made?
The vast majority, if not all, are man made.
It is theoretically possible to feed system specifications and special instructions to an "inventive" computer in order to automatically discover and exploit complex vulnerabilities. Whether or not this makes the viruses "man made" is another question.
What was the earliest usage of the Internet?
the term internet was first used in 1982 by eldon the term internet was first used in 1982 by eldon
Is the internet a global network of networks of computers?
Although it is not clear what the question means by the Microsoft network, the answer is most certainly No.
There is no such thing as the Microsoft network.
There is a rather large network used for internal purposes by Microsoft Cooperation. While undoubtedly large, it is highly likely that another cooperation has an equally sized or larger internal network in terms of number of computers, total wire length, speed or infrastructure complexity.
There is Microsoft networking, a combination of tools, servers, services and protocols. While widely regarded as not the fastest or most compact design and implementation, the related code will most probably not be the largest code ever written for this purpose.
Among non-technical items, there is a network of companies and affiliates supporting and supported by Microsoft cooperation. While this is not typically referred to as the Microsoft network, one might think of this group of companies and organizations as a network. Again, it seems highly unlikely that no other cooperation has a larger set of affiliates.
What process allows computers musical instrument to communicate with each other?
Musical Instrument Digital Interface or MIDI for short.
Are computer viruses bad for your health?
Computer viruses and biological viruses are not the same thing. A computer virus can not infect a person.
However, computers are everywhere, controlling lots of things. Irreplaceable data can be corrupted and destroyed by viruses. Also, mechanical systems which are controlled by vulnerable computers could be infected, and cause physical harm. And infected information systems can cause financial harm to companies which rely on them, and, indirectly, to employees and clients.
Loss and damage are different issues when related to the computer's hardwares and softwares. Losses are generally caused by improper management of files and folders.
Viruses may cause breakdown, but it reversible by formatting the computer. The individual who operates a computer must be often informed about the improvements provided by the developers of new sofwares, and by the operating system builder.
A computer may work nicely when the operator get informed through informatic forums, by asking questions and watching carefully what the more experient users say about this or that.
What are some of the ways computers change and evoled?
The evolution of the computer
An electronic tablet which has a WiFi connection, anywhere, free and can be used without a desktop computer.
What tool is offered by IBM to keep track of the software development process?
Rational Unified Process
How do you connect logitech lx5 cordless mouse to your computer?
Just press & hold little button on your usb receiver, and than press reset button on your mouse. So simple.
How do you reformat your dell inspiron e1505?
the laptop bios password cannot be erased by battery discharging
Which part of the computer carries out arithmetic operations?
The arithmetic and logic unit (ALU) within the computer's central processing unit (CPU) carries out arithmetic operations. Some designs also support a dedicated floating-point processing unit (FPU), which carries out arithmetic, trigonometric and logic operations based on floating-point variable types.
What is the most popular ports for connecting input and output devices to the computer?
Currently USB Ports are by far the most popular for connecting standard desktop I/O devices such as hard drives or CD-ROM Drives or Thumb drives.
However eSATA and Firewire are used as well to a lesser extent.
