What was the first electonic computer called?

ENIAC (Electronic Numeric Integrator and Computer). Was the first general purpose computer, which was used by the US army for calculating projectile trajectory.

The first electronic computer predated this by 3 years in 1943, COLLUSUS. But had only one task of decyphering German codes during WWII. It was so secret, that everyone thought that ENIAC was the first, until de-classified.

How does a computer help to entertain?

What bus allows processors to communicate with peripherals?

We have on a motherboard called a input/output device. There are multiple of types, but the most common are PS/2, DVI, and USB. There are wires connected to the device called a Bus. The bus sends data to the processor where it is interpreted as data.

Different between text based and graphic base OS?

A text based OS is an OS which doesn't have desktop just text. to let the OS do something, you need to type the command. Only certain applications for this OS use another view then text. A text based OS is for example MS DOS or your computers BIOS. A graphic based OS has a desktop and isn't just text on your screen. Windows 3.1 was the first graphic based OS. More recent graphic based OS are: Windows xp/vista/7

Is a bit the smallest unit of data a digital computer can recognize?

Bit

"A bit is the smallest unit of data that a binary computer can

recognize."

Where might one find a good selection of computer packages?

A good selection of computer packages should be composed of items such as office equipment (Word Document, Excel, Powerpoint), entertainment (Netflix, Media players), and protection against viruses (Norton Virus Protection). A good package can be found at 'TADNSW'.

What device made computer miniaturization possible?

The invention of the transistor is one answer. The invention of the semiconductor is another. Going further back... the invention of the valve.

How computer virus transfer from one computer to another?

Typically, a computer virus is a program that can infect other programs by including a copy of the virus program in them. The virus is designed so that it can change its shape or purpose over time. Moreover, it multiplies and joins either the program or the file, "hiding" there, it wanders from one computer to another. A computer virus can "attribute" itself to other programs, as they say, "infect" them. This "infection" leads to the fact that computer viruses can independently spread and multiply. As a result, a large number of computers can simultaneously fail.

For a computer to become infected with a virus, this virus must penetrate the computer. The virus can penetrate using portable devices that are used to transfer data between computers, through a local area network of an organization, through other computer networks (for example, via the Internet).

However, in addition to the virus penetrating the computer, there is another condition that infects the computer. This condition is that the program containing the virus should be executed at least once on the computer.

How do you find your ssid and your wep?

Depending on what laptop you have but

go onto start menu.

Hover over all progames then hover over the name of your laptop for example samsung.Hover over User Guide And click it.

You will then see a button that says start click it.

Then in the search bar Type in Caps SSID then search. it will tell you how to do it from there hope this information was helpful

What are user reviews of Windows Vista for a desktop computer?

Windows Vista received poor user reviews after its release. Many problems plagued Windows Vista, including enhanced security features that were intrusive and irritating to users, as well as a lot of software previously compatible with Windows XP no longer working. Over time, through service pack releases and various software updates, Windows Vista turned into a decent operating system, although it is now outclassed by the more recent Windows 7.

What the steps that tell computer how to perform particular task?

A program is a set of detailed instructions that tells the computer how to perform a particular task.

Where is the world's fastest computer?

Very fast thats why they are super computers

What type of computer protection device will protect against spikes and surges?

You can use two different types of devices depending on the type of protection you need. If you are simply trying to prevent the computer from being damaged you would use a surge protector, while if you were trying to protect it from turning off as well you would use an Uninterruptable Power Supply (UPS) which is more expensive.

You should be aware however, that a surge from a lighting strike can also travel through networking wires as well, and for complete protection, you should have those go through a surge protector as well.

Explain the operation for SRAM and DRAM?

SRAM(Static Random Assessable Memory)-where the word static indicates that it, does not need to be periodically refreshed, as SRAM uses bistable latching circuitry (i.e., flip-flops) to store each bit. Each bit is stored as a voltage.Each memory cell requires six transistors,thus giving chip low density but high speed.However, SRAM is still volatilein the (conventional) sense that data is lost when powered down.

Disadvantages are more expensive and also consumes more power than DRAM.

In high speed processors (such as Pentium), SRAM is known as cache memory and is included on the processor chip.However high-speed cache memory is also included external to the processor to improve total performance.

DRAM(Dynamic Random Assessable Memory)- Its advantage over SRAM is its structural simplicity: only one transistor (MOSFET gates) and a capacitor (to store a bit as a charge) are required per bit, compared to six transistors in SRAM. This allows DRAM to reach very high density.Also it consumes less power and is even cheaper than SRAM (except when the system size is less than 8 K) .

But the disadvantage is that since it stores bit information as charge which leaks;therfore information needs to be read and written again every few milliseconds.This is known as refreshing the memory and it requires extra circuitry,adding to the cost of system.

What is the price of a new Compaq NX7400?

The price of the new Compaq NX7400 is about one thousand dollars. The Compaq NX7400 is not on the same level as an Apple computer for an example, but comes with a myriad of upgrades which substantiate the pricey introductory offer.

Why do you require Microsoft paint?

You don't 'need' it - it's simply part of the Windows operating system. It can be uninstalled from the hard-drive if necessary.

Computer won't turn on?

3. Smash the on the keyboard (rarely works)

4. plug it in elseware

5. Get a new computer.

How do you become a computer expert?

In order to become a computer programmer you will need to obviously study and prepare, preferably by getting an IT degree, that would be the ideal scenario and also the most basic one, because the computer world is rapidly changing and programmers need to be up to date in order to be able to do a better job. So, it's all about studying hard, practicing and being all the time in the look out for the latest developments in industry.

Why are standards such as the ASCII so important?

Well, many people use it for art, like this ....../ `---___________ _____|] ......

...../_==o;;;;;;;;__ _____.:/

.....), ---.(_(__) /

....// (..) ), ----"

...//___//

..//___//

Ascii is also a code-of letters and numbers.....................

What is the Dell computer commercial I am green today?

It's a song interpreted By Kira Willey, called "Colors". Don't remember the name of the album Check Out amazon or Itunes store for details.

Why can't computers understand language?

The question is far too vague. What do you mean "understand and use the human language"? for what? Do mean can it respond to and speak human language? yes if its got the proper software that enables it to or are you talking about giving it commands by typing them in human natural language? That would be no because if you're typing a command in "human natural language" (which is what we all do) - automatically the computer translates the command into a binary language which it then processes according to the command its given.

If this is not what you meant then you must be less vague in your questions. Ask the question again and be very clear and specific about what you mean.
