How do you find information?

Searching the Net
  • Find a fully configured personal computer. Learn how to use it. You should be able to use your word-processing program, get online, and move to different websites. If you can't, get someone to help you learn.
  • Learn how to use a browser program like Firefox, Safari or Opera. These are the programs that will help you navigate around the websites.
  • Explore different search engines. These are massive programs that will search the internet for different websites. Some good search engines include www.google.com, www.dogpile.com, www.ask.com, and www.yahoo.com - type the address into your browser's URL box (you might need to add the "http://" at the beginning of the address, depending on your browser) and hit enter!
  • Once you have gotten to the search engine, type key words describing whatever you are looking for into their Search Box. For example, if you want to know how many people live in Podunk, MO, you would type "Podunk,MO population." You don't need to use capitalization or punction unless it is something like City,State. If you have a specific way you want the words to appear (like "Official Website"), or a specific phrase you are looking for (like "information on the internet") then surround that phrase with quotations - otherwise, the search engine will pull up every website with each individual word to show you!
  • Left click on the title of each website that shows up in the list of websites returned by the search engine. That will take your browser to the website. You can then hit "Back" on your browser toolbar, or just close the window by clicking the "X" at the top-right corner.
  • Keep searching until you find the info you need. Remember that you have a "History" list if you click the button beside your browser URL box - usually it will keep a list of every website you have been to during a certain time period.
  • Welcome to the web - the world at your finger tips!
Finding Information in the Real World:
  • Visit the library. If you do not know how to look up a book in a library, the librarian will by happy to teach you how to find anything!

  • Visit a bookstore. All bookstores have an information desk where you can ask someone to help you find a book or find information.
  • Read a newspaper. Your local paper will have tons of information, from what's going on, to the latest sports news, to what groups are meeting in your area this week.
  • Use an encyclopedia or dictionary.

- cables are ethernet cables that you can use to create a network between two computers?

Crossover cables are used to connect like-hardware devices or to connect anything other than a hub or switch to a computer. The crossover cable connects the four pins that are used to communicate traffic over the cable together between the two devices.

Most network adapters manufactured recently can automatically sense a straight-through cable and auto-switch accordingly. All gigabit NICs are capable of this.

What is the difference between advanced user and standard user?

Advanced users are the typical users with more technical knowledge.

Standard users are the normal ones who uses computers to just get the task done.

Why your system is getting shut down in short period time?

This could be due to two main reasons: 1. The power socket is faulty or may be the wire is damaged 2. The CPU might be overheating and thus to protect it computer shuts down automatically(if you see a message on next boot the computer was shutdown due to thermal event a message like this then this is you problem) as a solution you can try checking the cables and connectors and use a UPS(Uninterruptable power supply ) or checking for your heatsink fan is working or not

What is two step verification in computer terms?

A "two factor authentication" method requires two methods instead of traditionally only one way (in which passwords are by far the most common) to authenticate the user when logging in.

The most common form of 2FA is TOTP, or simply put, a secondary password/code that is randomly generated every so often to prevent potential attackers from gaining access to your account should your primary log-in password is stolen. In most cases, TOTP implementations involve the use of having a mobile device as the place for the one-time password in most "authenticator" apps because it's convenient and makes adds a bit of difficulty (meaning the attacker has to obtain the password AND your phone to get to your account).

Is it harmful to my pc if I shut it down first then pulling the power cord?

It's potentially harmful. Although the PC is powered down, the cord is still live as is the power supply unit (PSU) attached to it. Removing a live cord could cause an arc or power surge that may be harmful to the PSU and/or the computer itself. Most PCs have a rocker switch on the rear of the PSU (near where the cord is attached). This should be switched off once all disk activity has ceased and the power LED has gone out. You should also isolate from the mains supply before removing the cord, although it's good to allow a second or two for any residual charge to fully drain to earth. Reconnecting the cord is the reverse procedure: connect the cord to the PSU and to the mains (both of which should be off). Switch on at the mains, then turn on the PSU with the rocker switch and finally power up the computer itself.

Note that a PC often have several power states. Hibernation mode is similar to shutdown except the contents of memory are copied to a mass storage device which may take a little longer than a normal shutdown. Other than that they are both the same and the computer can be isolated from the mains once hibernation is complete. Restarting from hibernation should be quicker since the majority of the boot process can be completely bypassed. Standby mode is where the computer shuts down unused components to or conserves power by entering a low-power state, but never completely shuts down (there may be several states depending on which components are powered down and which are in a low-power mode). Do not isolate the computer from the mains whilst in standby mode as the CPU is still active and there may be occasional writes to the hard-drive by programs running in the background.

Which technology was used in fifth generation computer?

Fifth generation computing was a design program, starting in 1982, to use massively parallel processing. it's purpose was to lay the groundwork for supercomputers and artificial intelligence.

First generation used vacuum tubes.

Second generation used transistors and diodes.

Third generation used integrated circuits.

Fourth generation used microprocessors.

Fifth generation was to use massive parallel processing.

This plan was to last for ten years, after which it was considered ended.

and a sixth generation would begin.

Obviously, since over 30 years have passed, we have just barely begun using massively parallel processing. The most advanced personal computers use quad core architecture, while industrial versions can use thousands of sub-processors.

Which buttons are used to open close maximize and minimize the window?

To open a window, often times just by clicking on whatever you want opened will do the trick. Still, you can also right click on whatever you want opened and you will be prompted with a box, with an option of opening being present as well.

Now that whatever you want opened is opened, let's say for example it will be a Word document. To minimize it, you will see in the top right corner an icon which looks like this " _ ". Clicking once on it will minimize your page down to the bottom of your screen. To return it, simply re-click on the link which is now currently residing on the bottom of your page and voila, its back.

To maximize a page, click on the icon right next to the minimize icon (In the top right) It looks like a square. Finally to close a window, click on the " X " icon at the top right and away it will disappear.

If String str US then what is the value of str.substring(2 4)?

In C++, the return value will be an empty string because 2 is equal to the string length (the second parameter, 4, is simply ignored). If the first parameter were greater than the string length, an out_of_range exception will be thrown instead.

Why my PC starts to lag when I don't touch it for like 1 minute and everything like videos and games start to lag until I touch any key or the mouse?

It could be that if you are running the programs windowed mode. Programs that are not in focus (Highlighted/Selected) and run background mode which basically means less resources are provided for the program(s) that are not in focus and they will appear "laggy".

Or it could be that your computer has power save options enabled after a short period reducing the available resources to your loaded programs. You can check and change this in your power options in control panel(Windows OS).

If you give more information it will be possible to provide a satisfactory answer.

Who uses clocks?

Yes, they are very important. A clock is an instrument used to indicate, keep, and co-ordinate time. The word clock is derived ultimately (via Dutch, Northern French, and Medieval Latin) from the Celtic words clagan and clocca meaning "bell". A silent instrument missing such a mechanism has traditionally been known as a timepiece. In general usage today a "clock" refers to any device for measuring and displaying the time. Watches and other timepieces that can be carried on one's person are often distinguished from clocks.

The clock is one of the oldest human inventions, meeting the need to consistently measure intervals of time shorter than the natural units: the day, the lunar month, and the year. Devices operating on several different physical processes have been used over the millennia, culminating in the clocks of today.

The study of timekeeping is known as horology.
