On a Cisco router which interface would be used to make the initial configuration?
Ask in the computing category.
How do you burn AT89c51 microcontroller?
You'll need to acquire a programmer board and the application software.
The programmer boards typically plug into your PC and you can write an application using the application software, then you can load the application into the microcontroller using the programmer board.

How do you get binary data from the image?
You divide the image into two axes (X and Y), and work out positions across the image using a coordinate system. E.g. if the X axis is A - Z and the Y axis is 1 - 10, you can refer to a particular position in the image as C-8. If that C-8 grid or pixel is black, the value is 1, if it is white, the value is 0. In statistical analysis, this system is used to visually explore contingency tables-- the X axis can contain a list of categories and the Y axis can contain a list of cases.
Data error reading FAT what do you do?
Run Scandisk, and pray. Most likely the drive has suffered a catastrophic failure, or it could be something as simple as a power failure while writing to the volume.
What are the components of micro computers?
the invention of microprocessor (single chip cpu) gave birth to micro computers.
they are several times cheaper that mini computers.
classification of micro computers:
1.workstations
2.personal computers
3.laptop computers
4.palm PC's
This is a electronic work surface, and is used for importing data into your computer digitally. For example if you sketch something onto there (using the electronic work surface pen) this will processes this into your computer.
This is a CAD (computer aided design) digital table software.
What are five things you can scan with a flatbed scanner?
A scanner can be used to scan almost anything. A flat bed scanner could be used to scan a piece of paper, a book, a picture, some of are capable of scanning a small figurine, and documents (as long as it's legal for them to be scanned).
How many milliliters ink is contained in epson cartridge T0731?
I certain refillable cartridge claims are to be believed, less than 10ml. Cartriges with a volume of 14.5 ml claim to be 1.5x epson cartridge volume.
What is meant by floor planning in pcb?
Floor planning means planning for placement of components on a printed circuit board e.g. in which area the major components will be placed. This will depend on many factors like shape and size of the PCB, design flow in the circuit, any mechanical and thermal constraints, product functionality requirements and so on. It is important to do floor planning before starting routing the connections on the board.

Why p-substrate is used in monolithic IC not p-substrate?
entire circuit is built into a single piece of semiconductor (chip); physical properties of semiconductor to large degree determine performance of the circuit; the most common integrated circuits such as microprocessors, memories, etc., are all monolithic.
Do all computers have operating systems?
Practically all of them have O.S's, as I doubt that most people will ever see one without some mac o.s on it or xp or vista on it. However, all stock machines that are loaded/downloaded/installed with programs/software,etc come without operating systems. I have seen my share of them, as I used to work for a computer store myself, though DOS is nothing to brag about, unless you are some nerdy IBM veteran that designed it.
How has the speed of computers changed from when the first computer was made?
More computer workers started working on the computers and now its faster
The speed of computers has gotten a whole lot faster over the time from the first machines. The shift from vacuum tubes to solid state devices opened to door, and newer circuit design and engineering coupled to an increase in the sophistication of semiconductor manufacturing techniques has allowed faster and faster processors to be built.
How to convert RS-232 serial port to bluetooth?
You need to get a Bluetooth RS-232 dongle, which connects to serial RS-232 port and provides bluetooth connectivity. These are similar to USB bluetooth devices to some extent, but need a power source for the electronics circuitry (as you may be aware that USB ports have 5V power supply but RS-232 standard has no option for power supply on the connector). So Serial port to Bluetooth convertors will have either an inbuilt battery or a power supply connector to feed power. Here are examples : http://www.lemosint.com/scripts/bluetooth_parani_sd.asp

How can an obd machine read p0171 an p0172 at the same time?
If there's something wrong with the oxygen sensor, and it switches lean, then switches back rich to correct, it'll set off both codes.

Computers today make how many computations per second?
You are asking what the processing speed is and the answer varies for individual madels. The speed is measured in parts of a second (rather than by the second) and many newer computers are now built with two processors that work together to further increase the processing speed and capacity.
What is Friend class How is it different from Abstract class?
Friend class is one which has been declared so (as a friend) inside other class to make it access the private members of the class which has extended it's friendship.
For Example,
class A
{
private:
.......
public:
..............
friend class B;
};
class B
{
.......
..............
};
As in the above code snippet, class A has extended it's friendship to class B by declaring B as it's friend inside it's area.
Since the Class B has became a friend of A, B can directly access all the private members of A. But the reverse is not possible.
Where as an abstract class is a one, which doesn't represent any particular object in nature. Instead they use give as abstract look of an object.
For instance,
When we say TATA Indca, Lancer, Ford Icon, Toyota Innova they are different car models. Each of them having their own properties and features, but all of them are Cars. So here, Car is an abstract class where as the others are concrete classes.
How do you clean out computer?
Very carefully. Here is a free program that will help clean your registry. http://www.karenware.com/powertools/ptpruner.asp If you are referring to spyware then you need a spyware removal program. I recomend Ad Aware Personal, its free and works great. You can download it from www.lavasoft.com VERY CAREFULLY! It takes one slip to accidentally delete one file.. and your done. You can download a cleaning utility to help you, it's kinda risky to go in and start deleting files. Yes I would download a registry cleaning utility such as PCTOOLS Registry Cleaner - rids you of corrupt path files etc, compacts your registry to save space, and optimizes your system so that it runs faster. There are a few free registry cleaning utilities out there, you just have to look around. I don't recommend going in to your registry and deleting files, unless you want to stuff your PC up that is...

Why wont your microphone make noise?
Microphones are connected to input devices that read the voltage from them and hence are not driven to make noise. If you connect a power source to a magnetic or crystal microphone you can get some noise but not much. The speaker is very small and not designed for produciing sound Many microphones are dynamic and use capacitance. Hence you can not drive them like a magnetic microphone. Note: you can use a speaker as a microphone.
