Press Ctrl, Alt, up arrow but this only works on Windows Vista.

Laptop carts are available through many retailers, both on-line and in store. For a wide variety of options, you may want to look on Amazon's website. They offer many different styles and brands. If you prefer to shop in-store, you can check out Office Depot and Wal-Mart. Both stores also offer online options as well.

Think of it this way. If you had an identical twin and both of you are named exactly the same, how will people tell you apart?

It makes the computer circuits much simpler. It is fairly simple to have circuit elements that can have two different states, and to do operations (like addition or multiplication) on those states.

I suggest that you should sell your laptop go to reputable companies like Cash4laptops.com (VeriSign and TRUSTe certified) (Green Certified Site)

They offer you the right price for your laptop and Selling it into good hands means you contribute to keeping large quantities of toxic wastes like lead, mercury and cadmium out of landfills.

it cost about $20-$30.

There are many stores that one can get a 17 inch laptop backback at. Some stores that sell that are Walmart and Target, They both have a wide selection to choose from.

The IRS says computers need to be depreciated over 5 years. That was an absurdly long time, even when the rule was established. Most small businesses ignore the IRS regulations, and simply expense a computer as if it were a hammer or an electric pencil sharpener.

Yes, it is. Before you can download, you will have to log in.

Different types of buses:

P ISA (Industry Standard Architecture)

P EISA (Extended ISA)

P VESA (Video Electronics Standards Association, VL Bus)

P PCI (Peripheral Component Interconnect)

P USB (Universal Serial Bus)

P AGP (Advanced Graphics Port)

software is a general term for programs that control the computer system.

there are two types of software.

programs that allow the hardware to run properly, e.g.operating system-system software:

application software:programs that allow the user to do specific tasks, e.g.

spreadsheets.

Computers communicating with each other has allowed for many things that we now take for granted. The internet, for instance, relies on many computers communicating with each other to transfer information from one place to another very quickly. Banks rely on computers communicating to run automated teller machines. Stores rely on computers communicating to notify each of inventory and other things. Telephone systems now rely on computers communicating with each other.

This would be true. A data file is a file that contains the data which controls the operations of a program or task, which is the instructions for how to perform the task or run the program.

There are a few ways evil can find its way onto your computer. The most common way is opening attachments that supposedly came from your friend. Spyware and viruses can sometimes send messages with copies of the virus from your friend to everyone in their address book, pretending to be your friend. Rule of thumb: never open any attachment from any email that you didn't expect. Another way your computer can get infected is if you download a rogue file on the internet. Always check to see if what you're downloading comes from a reliable source. If in doubt, have an anti-virus program scan the file before you run it. The most malicious virus is a Trojan Horse program, a term used to describe a virus that pretends it does one thing, while it really messes up your computer. Be very cautious what you download and always scan what you download. Some websites phish other websites (pretend to be the true website), but phishing checkers are available on the internet. If you download a file that has an extension (such as .jpg or .doc) that you are not familiar with, immediately delete the file and double check the website to make sure that you're downloading something safe. Some programs freely admit to being spyware to prevent lawsuits (usually on paragraph 56 of the 57-paragraph license agreement). Bottom line: be sure of what you download and always scan it before you run it. Next, never start your computer with a floppy disk in the floppy disk drive. Not even that "game" (wink-wink) Bob slipped you last week. Your computer is most vulnerable as it starts up. As part of your start-up routine, eject any and all floppy disks. Finally, some evildoers can get into your network, destroy and vandalize, slip in some viruses, and run away unnoticed. This is only true if your router has any wireless capability. To counteract this, watch your windows for any masked men crouching by your house with a laptop in hand. Better yet, be sure to enable security for your router (usually go with WPA unless some hardware is incompatible) and create a strong, secure password. And don't get paranoid. 90% of what you download on the internet is safe, especially if the website you're using is either secure (look at the URL for https://) or is checked by third-party software (you'll usually see an ad somewhere on the page that says "Virus-Buster Protected!" or some other stupid slogan. Breathe a sigh of relief when you do.). Hope this answer helps!

One could donate an old computer to a thrift shop, or to a company in need of one. One could also go to the nearest dump, and place the computer in the electronics bin. The computer will then be salvaged for precious metals.

One who computes.

A dashboard is akin to the dashboard of a car, typically a software application that provides one or more graphical indicators of a computer system's performance, such as processor loads, RAM and resource consumption, hard-drive activity and condition, temperature's and fan speeds, etc. Modern desktop chassis often include a hardware dashboard that can present data, such as internal temperature, fan speeds and disk activity, upon a small digital display built into the chassis itself. Older chassis may only have an LED that blinks on and off to indicate disk activity, but a top-end chassis can provide continuous, user-friendly information.

Not all modems are a combined modem/router.

Some companys only supply the modem and if you have more then one networkable device then you can get a separate router yourself.
