What is the difference between a wireless LAN and a wireless G card?
N is faster and has a longer range (if you live in a multi-story home or apartment it is amazing). G is, of course, cheaper. If you are wondering, don't worry about the fact that the N standard isn't finalized yet. Most devices conform to the draft standard. Any change from the current standard will be minimal at this stage in the process and will most likely only require a firmware update if the final standard does in fact change... The extra cost for wireless-N makes sense if you need the improved range due to a large home or multiple walls between the computer and the base station. If you need to transfer files between other computers or stream music within your local network (you have a media center PC and want to stream music/video) you will benefit from the faster speed of wireless-N You won't get any extra speed boost from N if you are the only computer on your network and you are relatively close to the base station. Remember, even with an 8 Meg cable modem, the bandwidth of 54Meg wireless-G is more than sufficient.
My home Computer shuts down 5 seconds after being turned on?
This can be caused by a number of things. Here are some of the most common culprits.
Environmental. Have you recently added a space heater, air conditioner, refrigerator, or other heavy-drawing appliances to the same electrical circuit? The system may not be getting enough power, modern systems often have up to 600 watt power supplies, they can be very hungry beasts. To find out if this is your problem, you can try experimenting with plugging your machine into a different household circuit via an extension cord.
Over-taxed. Have you recently added more hardware to the computer? Adding a second hard disk or optical drive, upgrading the video card, or even using some of the power hungrier USB devices can over-tax the power supply of the system and the motherboard will power itself off if it isn't getting the voltages it wants. Additionally, if this is an older system the power supply may just be giving up the ghost, and just hasn't died all the way yet.
CPU overheating. If the CPU heat sink has become un-seated from the CPU it takes about 5 or 10 seconds for the CPU to heat up enough to shut down the system. Double check that the CPU heat sink is firmly attached & that none of the brackets has come loose.
My pet theory (and to be honest im only guessing here) is that one of your fans is having problems.
Most modern motherboards have the ability to monitor the speed of the cooling fans. These systems are often set by default to refuse to stay powered on (they'll shut off after a few seconds) if they detect that one of the fans is not spinning.
Most likely one of the fans in your computer has gotten stuck. Open up the machine and clean them.
Also, if one of these fans comes unplugged, the motherboard will get a 0 RPM reading & will shut itself off. If you've been monkeying around in there, or the machine was just recently assembled, make sure everything got plugged in right.
If you just built the system. It may have hookups for case fans. These hookups may be by default configured to shut the machine down if they dont detect a spinning fan. You may or may not be actually using these hookups for your case fans (you might not even have case fans) and so you would need to go into the BIOS menu and disable case fan monitoring.
What are reasons to assemble the computer by your own?
1) The overall cost of the Computer is greatly reduced
2) You do not have to deal with a middle man to get replacement parts
3) The range of parts available is huge, and customisation is down to you to make it how you want it
What setting you can configure from the BIOS setup program?
There are many things you can configure within the CMOS setup. The exact options depend on your exact machine and the exact BIOS. You can set the time, date, what boot devices you have, the boot order, and what to do about certain errors. You might be able to disable or enable online ports, onboard devices, Plug and Play options, what USB support is offered, and more. You might have advanced options you can configure such as memory timings, bus speeds, CPU speed, the generation of PCI Express that is supported, etc. There might be a video aperture size option and/or a PCI-Express latency setting.
Is touch screen input or output?
Both. There's a touch panel that is used to feed information in to the device (input) and a screen underneath the touch panel to display stuff (output). This makes it to be both input and output.
How do you clean the fan of a computer?
Cans of compressed air or gas may be found in most stores that sell computer gear and accessories. It's best to unplug the unit and take it outside, to blow out the dust. If you've never done this before, ask a knowing friend or a tech to help.
Why is my brand new computer so slow all of a sudden?
It could be a number of things. For example, it could be:
- Viruses, adware and/or malware could, unknown to you, be running in the background and taking up resources that would otherwise be used by programs you choose to run
- You may have multiple windows open. Each window open will take up a certain amount of resources. Having too many windows open can slow down your computer
- You haven't got enough memory to support the program/programs you wish to run
What is the difference between a chipset motherboard and an original motherboard?
In an original motherboard, the entire product is manufactured by Intel, i.e. the circuit board and the ICs (integrated circuits) which are on it.
Whereas, when we talk of a `chip set' it means some other company, for instance Mercury or D-Link, has designed and made the circuit board but has used the chipset provided by Intel.
When we refer to a `chipset" it is a set of ICs that primarily controls the processor, memory and other main functionalities. However, the third-party company that has designed the circuit board can use other company chips for audio and other communication peripherals. The major point to note here is the design of the mainboard.
The chipset consists of two major microchips. These are known as the North bridge and the South Bridge.
The North Bridge Handles data for the AGP Port and the main memory which includes the FSB (Front side bus). Although both chips are required for the PC to work the North Bridge handles most of the very important tasks such as the connection between the CPU and main memory.
The South Bridge handles data from the PCI and ISA slots and can also have integrated components such as Audio codec's etc.
Power over Ethernet is a system whereby a small amount of electrical current is sent over the network cable. This is done so that some devices can draw power from the network itself thereby eliminating the need for an electrical outlet. This is generally only used for low-power devices such as cameras, routers and the like in places where it would be inconvenient or expensive to run mains power.
What is the difference between ports and bus?
Based on the definitions at the associated links, a bus is an electronic connection which allows the transfer of information, whereas a port is a socket in the side of a computer which allows a matching plug to connect to that computer.
What does the term megs stand for?
Shorthand for "mega." For example, 10 megs means 10 megabytes. It generally refers to bytes, not bits.
What does a 100 mbps maximum speed mean?
The ISP allows, or can provide, up to 100mbps of data transfer between your computer/connected devices, to anything else.
Who uses the mainframe computer?
MAINFRAME is a some what antiquated term for a main server or a large machine capable of a workload much beyond the capability of a standard desktop unit. Also called "servers" or "Big iron" or even "gibsons" after the author of sci-fi novels the term has fallen into disuse these days.
Rare is it to see people putting all their money into a mainframe any longer. Parallel computing and cluster computing has enabled server farms to do the work of a mainframe for less money and less power! If you wish to see an example of what might be called a "Mainframe" check out the manufacturer "Cray" for some of their super computers.

How is the speed of a computer mesured?
The speed of a computer mouse is measured in dots per inch. If this number is high, the faster will be your mouse. Usually a computer mouse with 400 to 800 dpi will give you good experience.
Your answer is good ID3415191556
but I (SWARNIM)will like to add that, speed of mouse is measured in unit known asMICKEY.Less than 1mb. There is 1024kb in a meg. 736kb is far less than 1mb.
When removing the cover why should you take care to remove only the screws that hold the cover?
When removing the cover from a computer, you should take care to remove only the screws that hold the cover on. Otherwise, you may remove more than what you intend. For instance, unless you want to remove the power supply unit, there is no reason to remove its screws.
What is one reason to flash a BIOS?
If your motherboard becomes unstable,or you lose some functions like a USB port stops working, or you are tyring to take advatage of a new feature or component then you might need to upgrade the ROM BIOS chip by flashing it.
Can you save music from you tube to your memory stick?
To access a YouTube video from a USB Stick, you will need to convert the Flash File on YouTube to a Video File. This file on your computer (normally in the Downloads folder) should be put on your USB, which can be accessed from My Computer on a PC or Finder on a Mac.
