What are the disadvantages of overclocking?
Overclocking can permanently damage your systems hardware if you overclock to much. It is normally the heat that kills your computer in a nutshell. Overclocking should only be done after doing your research.
How do you find the 2.0 USB port on a laptop?
the USB port should be along one fo the four sides of the laptop. they are rectangulare in shape. do a google image search of "USB port" if u are unsure of what one looks like.
What is smallest addressable unit of storage on a disk?
It is called a block (or sector). The size of the block varies depending upon the size of the disk, advanced preferences (the size of files normally being used on that disk), and the filesystem being used. They normally run from 512Bytes to 64KiB. As disk capacity continues to grow, look for even larger block sizes to come :-)
Can you add another drive to a raid 5?
Do you mean add a disk to an already existing raid array, or can you have more than the 3 disk minimum? Either way, yes you can, though I find if you already have raid 5 setup with 3 disks and you want to add another one you are better off starting it all over from scratch again. As far as I can remember, I may be wrong, but all the disks have to be equal. You cant have a three 40GB drives at 5400rpm and then add in a new drive off 120GB at 7200rpms. And are you using a raid 5 hardware option or software option. If your doing it via hardware you may need to upgrade your disk controller. And dont forget your going to have convert your new disk when you get it. Drives are usually basic, raid5 wont work on a basic disk. Actually you can add disparaging disks to an array but you'll only get the capacity of the existing disks in the array - therefore in the above setup, adding the 120Gb@7200rpm wouldn't give you the capacity of the 120Gb, only an additional 40Gb.
What The hardware component used to control the operation of a computer system?
The operating system communicates with computer hardware using small programs called drivers.
What keyboard key can you press to get full screen?
On a Windows PC press F11.
On a Mac computer click the double arrows top right of browser. To return to regular screen press esc.
What is input in a computer system?
The "Input" term used in computer refers to one of the three major computer items: Input, Processor, and Output. Some of the "Input" items are Keyboards, Mouses, Touch Pads, etc. Furthermore, in programming, "Input" is used when the programmer wants the user to input (enter) information such as his name. So, "Input" means what is sent TO the computer. On contrary, what is sent FROM the computer is "Output" such as Screens, Printers, etc.
What is the difference between a wireless NIC and an Ethernet NIC?
Wireless is just that; it's a wireless connection to your modem or router, which works by sending information through the air, much like cell phones or radio. By that same token, it is subject to interference, and people other than yourself may be able to remotely access your Internet connection if they can get past whatever security you've set up for it.
Ethernet cable on the other hand is a physical cable for sending the same information; because it is not subject to the same interference as wireless, it is more reliable. Furthermore, if you make it so that you need to physically connect with a router, you can completely prevent the above scenario of someone hacking into and using your Internet connection through wireless.
However, getting that physical connection can be arduous in a household with multiple computers because you need to find a way to get the cable from those computers to the router; avoiding this one-time hassle is why many people choose to use wireless instead.
What is the difference between a eeprom and flash?
EEPROM is an older, more reliable technology. It is somewhat slower than Flash.
Flash and EEPROM are very similar, but there is a subtle difference. Flash and EEPROM both use quantum cells to trap electons. Each cell represents one bit of data. The presence - or absence - of electons in a cell indicates whether the bit is a 1 or 0.
The cells have a finite life - every time a cell is erased, it wears out a little bit. In EEPROM, cells are erased one-by-one. The only cells erased are those which are 1 but need to be zero. (Writing a 1 to a cell that's 0 causes very little wear, IIRC)
In Flash, a large block is erased all at once. In some devices, this "block" is the entire device. So in Flash, cells are erased whether they need it or not. This cuts down on the lifespan of the device, but is much, much faster than the EEPROM method of going cell-by-cell.
Erasure method: Both Flash and EEPROM erase cells by means of an electric field. I think it is high-frequency and "pops" the electrons out of the cells, but I am not certain.
Other similar devices are EPROM (sometimes UVEPROM) and OTPROM (sometimes PROM). EPROM/UVEPROM lacks the structures that generate the electrical field for erasure. These devices have a window on top, usually covered by a paper sticker. To erase, the sticker is removed and the device is exposed to intense ultraviolet light for 30-45 minutes.
The only difference between OTPROM and UVEPROM is that OTPROM lacks the UV window - there is no way to erase the data. Adding the UV window to the device package significantly increases cost, so there is a niche for one-time-programmable devices.
How can you transfer torrent files to your windows media player library?
I tried putting the file under a file that the library is supposed to look in and automatically transfer, but when I hit OK it said files found: 60, files added: 0. What do I have to do to add these files?
How can you examine events after you have cleared them from the Event Viewer?
You can view the events in the recycle bin. When you delete the events from then event viewer, the automatically go to the recycle bin.
What is the difference between the locations of discrete L2 cache and advanced transfer cache?
On-Package L2 cache (discrete L2 cache) is on a separate microchip within the processor housing, while Advanced Transfer Cache (ATC) is located directly on the same die as the processor core.
Pressing keys on a keyboard sends information to the computer that would, for instance, type characters on the screen. Therefore, making a keyboard an "inputting" device.
What is the difference between a workstation and a mainframe?
A network is a group of interconnected communicating devices (computers, portable devices, routers, modems, printers etc.)
While a mainframe is a centralized server which provides primary services to a network or multiple networks. Typically, the term 'mainframe' is differentiated between 'server' by way that a mainframe provides service to dummy or smart terminals. Terminals do little or nothing by themselves, and require an established link to the mainframe to boot or function basically.
A dummy terminal has no processing capability and boots off the mainframe over the network. IE, it's little more than a network card, monitor, and keyboard. Most ATMs and credit-card machines are dummy terminals- If the mainframe goes down, they become inoperable.
A smart terminal, which is more common, has it's own processing capabilities. A desktop computer is an example of a smart terminal, as it can function even if offline. Also, typically, smart terminals will load data from the mainframe then store it on the terminal itself, rather than running entirely from the mainframe.
How do you turn on microphone on dell inspiron 1750?
Well an easy way is to open up sound recorder and click record and once you play it back you hear sound its in there if not then it doesn't
What is the difference between a monitor and a desktop?
A monitor is the viewing screen, a desktop consists of your cpu, computer components.

Why it is called 8080 processor?
The 8085 microprocessor was an enhanced version of the 8080, primarily running on a single +5V power supply, hence the designation 8085.
The 8086 microprocessor was an enhanced version of the 8085, primarily running as a 16 bit processor, hence the designation 8086.
The 8088 microprocessor (part of the 8086/8088 family) was a version of the 8086 that run on an 8 bit bus, hence the designation 8088.
Why do you call usb a flash drive?
USB is not a flash drive. A flash drive is so called because it uses flash memory that retains data with no power.
What is the difference between an end device and a networking device?
Internetworking devices which means its efficient and performance is up to the mark. But in networking devices there is a lot of problems when we are sending the packets from one computer to another computer.So its difficult to work with networking devices compare to interconnecting devices. Cost is moderately high in this..
