Name four different storage devices?
Let's see:
Harddrive
Solid State Memory (RAM)
Optical (DVD / CD / Etc)
Memory Cards? (SD Memory / CF Memory / Etc)
Technically the last would be the same as RAM, but it isn't used the same. RAM is used in most computers as temporary memory. This memory only retains information while power is provided to it. Once the power is removed then it loses everything. With a memory card type of memory such as NAND type of memory, information stored in the memory card is retained even when the power is removed (USB memory sticks / SD memory / etc).
What are some good back up data solutions companies?
The best and most trusted back up would be to do it yourself onto discs or external hard drive. Symantec is a very good data solutions company with a good reputation.
Which disk drive standards uses an 80-conductor cable?
The drive interface that uses an 80-conductor ribbon cable is IDE. IDE stands for Integrated Drive Electronics, an interface commonly used to connect hard disks and optical drives to computers.
Why does Designating the Hard Disk as the only bootable device increase system security?
Because alternative media won't boot with alternative operating systems.
Read only memory (ROM)
How do you remove the password from a laptop hard drive IBM T41 Hitachi hdd?
You remove the hdd from the laptop, write down the model number, phone your IT supplier but an identical hdd and fit it to your T41. Then recover using the recovery disk. Your old password'ed hdd is good to use as a paperweight.
How do you remove the hard drive from a Toshiba 460cdt?
Look at the front of the machine beside the activity LEDs. You'll see a panel. Turn the machine over and unscrew the panel, theres only one screw holding it on. Now, it takes some working to actually get this cover off, but it will come off eventualy. Inside there you'll find the harddrive, its just a simple matter of unscrewing it and pulling the cradle out.Refitting is the reverse of removal.
Where is information that you view on the intenet stored on your computer?
Everything you view on your web browser, ie: internet explorer; firefox; safari etc. Are usually saved in your temporary internet files.
There are several programs out there to clean up these traces of personal data. Once in particular that I use is IOBit's Advanced System Care. Its free and spyware free. It runs periodically in the back ground to clean up privacy traces as well as speed up your computer.
This is not a spam message, I'm just some guy with the right answer for this one. Most things that you view on your computer are saved SOMEWHERE. Even when you delete a file it is moved to the recycle bin first, before it is completely removed. So clean up your Temporary Internet Files and your Recycle Bin. Those are just two of the places. There are just too many specific's to list. I'm sure most of your arent computer technicians like myself. So just go get the above mentioned program and save yourself a head ache.

What should a person look for when selecting a hard drive?
It's quite simple, you need to evaluate your need for storage first and how much this disk will be accessed (from 1 computer or more). If you install losts of software and/or do a lot of video/audio capturing, youll need a large hard drive (100GB or more). Speed is not really an issue here since practicly all newer hard drives turn at 7200 RPM.

On Windows, those are usually referred to as "drivers." On Mac OS X, they are referred to as "kexts", or "kernel extensions." On Windows, if they are not already built into the kernel, they are called "modules."
Where can you buy IDE hard driveS?
One can purchase an IDE laptop hard drive from Discount Tech or Office Depot. Discount Tech is an online store that sells quality products and is very reputable. Office Depot is also reputable and sells name brand items cheaper than most stores.
What happens to the inode when you move a file within a filesystem?
nothing really. the inode contains data about where that file exists within the directory / folder structure. so the inode is just updated with the new location. Also note that this is more or less how it works on all operating systems.
How many IDE devices can a typical mainboard support?
A typical modern motherboard has 1 IDE channel, which can support 2 devices. IDE has been replaced by Serial ATA (SATA), so modern boards have 2 to 8 SATA ports. Older motherboards may have 2 to 6 IDE channels, which could support 4-12 IDE devices.
Difference between CD rom and hard disk?
The difference between a CD Rom and a hard disk is that a CD Rom translates the information on CD's and discs. On the other hand, a hard disk stores data and useful information.
Why YOU choose database system instead of simply storing data in OS?
Operating System (OS) files do NOT hold data for your personal use. Any data in an OS file is used STRICTLY by the OS.
A database system is used for storing data of any kind. A text file is not stored data, so you wouldn't use a database for THAT. But a dictionary of words used in the text file, along with their definitions, could use a database.
Even pics can be stored in a database, and even a list of other files can be stored in a database.

How do you transfer filesfolder from one drive to another drive?
The best way to do it is to right click the original file and select "copy." Then proceed to "My Computer" locate the second drive and open it. Once it is opened right click any empty space and select "Paste." Good luck!
What is the random operating memory?
There is no such thing.
random access memory maybe? RAM
ROM = Read Only Memory, not Random Operating Memory.
Is a optical drive a input device?
It's input I think, not that sure, but I just know that it reads data from a disc and then views them onto the computer screen. :)
Is a hard drive an input or an output device?
It is neither. In addition to input devices and output devices, there are devices called storage devices. The hard drive of a computer is a storage device: it contains the operating system and any data or program files used by the computer.
Although a hard drive both accepts input and provides output, it is not accessed directly by the user in either of these functions. A flash drive, CD, DVD, or external drive are other storage devices or media. In early computers, drives wrote to removable disks as CD burners and DVD burners do today. These types of media-writing hardware are considered output devices.

It's both, or neither, depending on how much of your hardware you choose to define as "your computer."
Since a device is basically something outside your computer that the computer communicates with, the answer to this question depends on what exactly you consider to be the boundary of your computer.
First of all, from the perspective of your computer's motherboard and in particular its central processing unit (CPU) chip, which actually do the "work" of the computer, a hard drive is clearly both an input device (because data can be read from it) and an output device (because data can be written to it).
On the other hand, if you define "your computer" to be "everything inside your computer's case" as much of the general public does, then an internal hard drive would be merely considered part of your computer as a place to store data (similar in this respect to computer memory, but slower), and only an external hard drive (one plugged in to the outside of your computer by a cable) would be considered an input/output device.
People involved with designing computer technology for a living (programmers, hardware designers, etc) tend to take the first view, while people involved with the business of making or using computers (computer repair technicians, computer salespeople, and most of the general public) tend to take the second view. Neither is really "right" -- it all depends on where you choose to draw the boundary between what is part of your computer and what isn't.
Some people that there are three types of devices, not two: "input devices", "output devices", and "storage devices." With that set of definitions, a hard drive would be neither an input device nor an output device, but would sit firmly in the third category, as a storage device.
It's called the 'recovery' partition. Various manufacturers will put recovery partitions on certain computer models and not others. Many (older) models came with recovery CDs or DVDs. Newer models expect you to burn recovery media from the recovery partition so that you can recover a system on a new hard drive if the old one fails. You can also try downloading from the computer company web site and burn it to recovery media.
Difference between hard disk and DVD?
a flash disc can store info such as a project you do on Microsoft or something. While a DVD can only store video.
Where can I buy an internal hard drive?
You can buy any hard drive at your local electronics store and online, there are many good deals online. You will see the performance difference between the hard drives with how much data they can handle in a second.
What is a safe ambient temperature for your computer?
External case temperature should always be below 27*C (80*F), with the best temperatures around 18*C (65*F). Internal air temperature should be around 40*C (104*F), except for heatsinks, which require lower temperatures.
As long as you're using fans, don't be worried until case air temperature exceeds 55*C(130*F). At this point, both fans and passive coolers will be useless, and only liquid cooling will be able to safely protect your components.
These are units of storage capacity, not performance. Hard drives can read and write data faster if the platters spin faster. The number of platters will also greatly affect your read and write speeds. Assuming that both drives spin at the same speed, have the same number of platters and are the same physical size, the 120GB hard drive will be slightly faster. It probably won't be noticeable. In terms of storage, 80GB is often much more than a user will ever need, despite the average drive today being hundreds of gigabytes in size. Unless you have over ten thousand mp3 files, have many bleeding-edge games or store DVD quality movies, the extra 40GB will not affect you at all.
