When did windows 2.0 come out?

Microsoft Windows 2000 is a computer operating system that was succeeded by Windows XP. The original released of Windows 2000 was on February 17, 2000.

What is a television designed to do?

The television revolutionized the way information is disseminated to large populations. For the first time in history, large populations of people could received the same information in a single setting (though the information could be interpreted differently) allowing for little degradation (improperly redistributed information from a third party source).

Where can you get a free internet phone number?

You will most likely not find a free phone unless it is a scam. Wireless carriers offer subsidies on a lot of phones when you sign a contract with their service and sometimes those subsidies are high enough to make the phone free. I would recommend checking with local wireless providers and see if they can help you out.

What is meant by the term wireless revolution?

Is means in simple terms the replacement of wires used for communication to a wireless environment. For example, local area network (LAN) has been replaced by WLAN (Wireless LAN), similarly fixed line telephones have been replaced by mobile hand sets including satellite handsets.

What happens when you put metal in a microwave?

Running a microwave oven with metal in it will result in the reflection of the microwave energy off the metal. There is an exception, and that's the problem. Let's look at that.

If metal in a microwave is in a certain shape, that is, if it has a certain geometry, it can act as a microwave antenna. It can cause the microwave energy to generate "specific" electric currents in the metal, and voltages can spike high enough to create electric arcs in the cavity. That's bad. We can use metal in a microwave (like to cover the ends of drumsticks), but we must follow the manufacturer's instructions when doing so.

What is VxWorks?

vxworks is used to control network and communication devices. vxworks is similar to unix but it uses less processing power than unix.

How do you program a uniden bc 142xl scanner?

When you set up a Uniden Bearcat BC148XLT base scanner, you must program the frequencies you want to scan based on your area's frequencies. You do not need to include weather frequencies, because the BC148XLT includes weather frequencies pre-programmed in the base. You can add frequencies to your scanner in minutes, allowing you to customize the frequencies you scan.

  • Press "Manual" to stop the scanning process. Press the number for the channel you want to program using the keypad on the scanner base. Press "Manual" after the channel number.

  • Enter the frequency, including the decimals, using the buttons on the keypad.

  • Press "E" to store the frequency.

How does thickness of a wire affect resistance?

Resistance is inversely proportional to cross-sectional area. so ,if the thickness of the wire increases, the area of cross-section increases and this results in decrease of the resistance.

The resistance R = l p / A

where R is the resistance, l is the length of the wire, p(rho) is the electrical resistivity of the material and A is the area of cross section.

So R the resistance is inversely proportional to A the area of cross-section. If R increases

Where was car radio invented?

The car radio was invented in Chicago, Illinois, USA by Robert Galvin. He went on to found a company named for his new product: Motorola

Unofficial/undocumented Answer:

Neal Kyser McNaughten (and probably others) Although there is no documentation to prove it, my father, Neal Kyser McNaughten, born in 1911, built a radio into a Model T some time in the late 1920s. It had a paper cone and used it's own dry cell since the car had no battery. He claimed that it was particularly of interest to the young ladies...

What is a cassette player used for?

Cassette cases are used to store and give protection to cassette tapes. These cases help prevent the cassette from getting broken, cracked, or damaged.

How do compound machines work?

A compound machine lets you trade out energy force and effort. Example: If you have a wheelbarrow and 50 pounds of bricks what would you use your bar hands are the wheelbarrow. Of course the wheel barrow cause it is much easier to use.

How do you type a heart on an iPad?

The iPad Facebook app does not have emoticons, but you can add them by installing apps like Emoti HD. These programs work for posts and updates, but not for comments.

What is computer logic gates?

Logic gates are transistor circuits, normally arranged on a silicon base and encapsulated inside an integrated circuit. (chip).

Using several transistors wired together, their inputs can be arranged such that, for given inputs, the output will only change state for certain conditions.

The transistor switches are in either of two states, 'on' and 'off'. These are logic states 1 & 0 (one or zero), hence binary.

The logic uses Boolean algebra.

NOT, means it is 'not on', = OFF. This is abbreviated in the descriptions as the letter 'N'

A simple AND gate, means that the output is at level zero until both inputs have a level 1 voltage on them.

A NAND gate is a 'Not And' gate. The result is reversed. The output is always at logic level 1 until both inputs also have a level 1 also.

Does an orange make a better battery than a potato?

i dont know some one outside of me please improve this answer it is for my science project

As this is for a science project, it would be wrong to simply give one answer. In fact, there are several things to test when deciding which is the best fruit or vegetable for a battery.

First, take a potato and an orange. Use different types of electrodes - try to get hold of steel, copper, zinc and aluminum. With each pair of electrodes, measure the voltage they produce. Then measure the current they produce. Finally, measure how long each one will operate.

Put the results into a table and then you are well placed to make your own evaluation of the data. The experiments won't take long to do and following the guide above, you will have enough information to get a real answer.

How does coating with plastic help prevent rust?

It prevents oxygen and moisture from combining on the metal which would create rust.

What condition are necessary for a current to be present in a circuit?

The only two things needed for current flow are electromotive force or voltage and a conductor. The amount of current flow will depend on the "Resistance" in the circuit.

Why was the iron invented?

A method of burning coal as a fuel in making iron was developed in the 1830's. Demand for iron in manufacturing was very high. As American industry became able to make it's own iron, industries that made machines, farm tools, rails, and parts of railroad cars grew very quickly.

What was the name of the first website?

Depends on your definitions of "public" and "website," but the first one was probably the World Wide Web Consortium's World Wide Web Project's start page.

Here's a copy: http://www.w3.org/History/19921103-hypertext/hypertext/WWW/TheProject.html

How much songs can hold in 160gb?

Of course, this all depends on:

1) How compressed the file is (Bitrate)

2) How long the song is (Seconds)

3) Compression codec used

4) Ultimately, this translates to what is the average file size (in MB) of the songs.

So... there are 1024 MB in a GB, so 1024 * 160 MB in 160 GB or 163,840 MB in 160 GB.

If the songs are of an average file size of 4 MB then 160 GB would store 40,960 songs.

Are Sony TVs good?

Sony does make a very nice plasma t.v yet there are other brands that are just as good such as Samsung and Panasonic.

How many bits can a CD hold?

CDs are a popular way to store and transport information and pictures. Users who are trying to determine how much room a disc contains will find a CD holds over five billion bits.
