Under 13 should only use the internet under adult supervision.
Why we use computer why computer is usefull what are the benefits of computer?
They operate with amazing speed, reliability, consistency, and accuracy
Spellcheck is great too. Ahem.
Hmmm... another homework question. It never ceases to amaze me how many kids don't want to do their homework so they just ask the questions here.
What is the description of being a computer technician?
Work or edit the infrastructure, the hardware, and or programming of a computer but you only do this to repair or reconfigure not build it for yourself.
C program to find address of variable?
// Use the & operator (Sometimes called the "address of" operator
int variable = 7;
printf("Address of variable = %d\n", &variable);
printf("Value of variable = %d\n", variable);
What is the difference between cobol-74 and cobol-85?
COBOL-85 is a later version of COBOL language. COBOL-85 also known as VS COBOL-II provides more features than COBOL-74. Some of the features of COBOL-85 are:
1. In COBOL-85 we can use following delimiters such as END-IF, END-PERFORM,END-STRING,etc.
2. We can use EVALUATE verb in place of complex IF structures.
3. CALL statement can pass variables by CONTENT and BY reference. In COBOL-74 we can only use pass by reference.
4. A new verb CONTINUE is introduced in order to over come the limitations of NEXT SENTENCE verb.
5. COBOL - 85 supports 32 bit addressing mode.
UR'S Rj
i had the same problem and it was the crank sensor. Have it scanned it should put out a code letting u know. I HAD THE SAME THING JUST HAD MY CAM SHAFT MY CRANK. SHAFT sensors put in along with transmission something and something emissions control valve and so far its doing great
What is the difference between bootstrap and operating system?
Bootstrap is a process to initialise any hardware components in a device. In the case of a computer it initialises all the hardwares so that it can talk to each other and function together. While OS is used for those components to understand commands and requests made by us. so OS is kind of interpreter or a link between us and the device while BS is an internal program to initialise the components.
Bootstrap is the process where a computer, after doing whatever self initialization and testing it needs (called POST for Power On Self Test for a personal computer), somehow establishes which device it is to use. Bootstrap is also called an IPL (Initial Program Load). The device is initialized and started with a command to read an initial bootstrap program from a predetermined location as the beginning of the device:
- For a hard drive, diskette or optical media, sd card or usb flash drive it would be the first sector/track of the formatted device. On a Personal Computer hard drive, it is called the MBR (Master Boot Record)
- For a tape device, it would rewind the device and read the first block of the media.
- For a tcpip network, a computer would send out a request for an IP address and bootstrapping information. if it receives the desired response from a DHCP or BOOTP server, it will request and download a bootstrap file.
After loading (or downloading) the initial bootstrap file into memory, control is transferred to it. Its main job is download a larger amount of program code from a known or determined location, which will get more program code until the operating system is fully installed and started.
- On modern computers, determining the bootstrap device is set in the BIOS as a list of preferred devices to check in sequence.
- On some older computers, this was done by setting control panel switches to the device desired.
- On less sophisticated computers, a short program of between five and twenty actual machine instructions are toggled in to specific addresses. Starting the computer at the beginning of this program results in the IPL process being performed.
How many people have computer in India in 2009?
The amount of JAI HO'S in INDIA that own the electrical device known as the computer is 5/10 native Indians
Which two noteworthy ideas in computer evolution are credited to Konrad Zuse?

- Invented the first programmable computer in 1941.
Best thing to do is to get a good anti virus software: AVG its completley free and top rated.
also a firewall is to be needed and a good one is: Zonealarm its completley free and top rated aswell.
If you have zonealarm it always asks you whether to allow or deny a software/file accessing the internet.
I have them both.
Hover Buttons are a feature of FrontPage 98 that allows you to create buttons that change form or colour when the mouse pointer is moved over them. As such, they are great for producing a navigation bar for your site, like the example below:
What key contains information about which application is associated with certain file types?
Hkey_classes_root
How can you take pictures on your ASUS netbook?
Please clarify Take on or from? From... If from you can use a webcam and on use Printscreen
How to make a line follower without microcontroller.Please also provide links?
There are several examples of BEAM robots which are line followers. BEAM robotics uses simple logic chips for the "brain" like the 74AC240 which costs $1 or so. The rest of the components are discrete components which means no microcontrollers are involved - only the usual parts like diodes, resistors, capacitors etc. I've included 2 links in the "Related Links" section below.

A puck is a mouse-like pointing device. It is typically used with graphics tablets, along with a stylus. Some pucks look like a mouse, while others are fairly large device with many buttons and/or other controls.
How do you save pictures from jcpenney's smiles by wire to your computer?
This site no longer allows portraits to be "right click" saved to your computer.
A common method would be to shorten the length of the fields - or - change the font size of the data.
Is the spreadsheet calculation set all the instructions that direct the computer?
No. An instruction set is all the instructions that direct a computer.
Where can you buy computer enclosures?
Computer enclosures can be purchased from any reputable electronics store which sells IT hardware. It will depend entirely on where you live and whether there is a store nearby whether you would be better off buying in store or online.
