What does the slave and master and the rest of the things for a hard drive mean?
To allow for two drives on the same cable, IDE uses a special configuration called master and slave. This configuration allows one drive's controller to tell the other drive when it can transfer data to or from the computer. What happens is the slave drive makes a request to the master drive, which checks to see if it is currently communicating with the computer. If the master drive is idle, it tells the slave drive to go ahead. If the master drive is communicating with the computer, it tells the slave drive to wait and then informs it when it can go ahead. The computer determines if there is a second (slave) drive attached through the use of Pin 39 on the connector. Pin 39 carries a special signal, called Drive Active/Slave Present (DASP), that checks to see if a slave drive is present. Although it will work in either position, it is recommended that the master drive is attached to the connector at the very end of the IDE ribbon cable. Then, a jumper on the back of the drive next to the IDE connector must be set in the correct position to identify the drive as the master drive. The slave drive must have either the master jumper removed or a special slave jumper set, depending on the drive. Also, the slave drive is attached to the connector near the middle of the IDE ribbon cable. Each drive's controller board looks at the jumper setting to determine whether it is a slave or a master. This tells them how to perform. Every drive is capable of being either slave or master when you receive it from the manufacturer. If only one drive is installed, it should always be the master drive. Many drives feature an option called Cable Select (CS). With the correct type of IDE ribbon cable, these drives can be auto configured as master or slave. CS works like this: A jumper on each drive is set to the CS option. The cable itself is just like a normal IDE cable except for one difference -- Pin 28 only connects to the master drive connector. When your computer is powered up, the IDE interface sends a signal along the wire for Pin 28. Only the drive attached to the master connector receives the signal. That drive then configures itself as the master drive. Since the other drive received no signal, it defaults to slave mode.
How did you know when your new aspire e 15 is fully charged?
You can turn it on and it will show indication of the battery percentage. You will also notice that there is light that glows up when you connect charger. There are changes in laptops over the years. If the light is blinking then wait for it to glow continuously which will mean that it is charged. If the light orange then wait it to turn green.
This depends on the context.
Formally, in a workplace context, marginal failure is defined as minor injury or minor occupational illness, $1K to $100K equipment loss, one day to two weeks downtime, or a loss of last period's data or short term (less than one year) environmental damage.
In more common computer lingo, it often refers to partial system failure, constant partial malfunction or failure that doesn't keep the machine from booting.
Ansuwers Came From:Power supplies have large capacitors in them. These capacitors store electricity in them even when mains power is shut off. If you were to touch the connections on the bottom of the capacitors, you could receive a potentially lethal shock. For this reason, you should never disassemble a power supply unless you have received training in how to properly discharge the capacitors.
Because of the big electric charge held within the capacitors inside it.
Computer power supplies have very large capacitors (elements that store charge) that could give you a very powerful shock if you managed to discharge them. They're like batteries that let go of all their charge at once.
Capacitors store energy (power) for an indefinite time. Touching both leads of any charged capacitor can give you a real good jolt.
For example, the tube of an old-fashioned television set is a giant capacitor in electronic terms: even though a TV may have just been switched off and unplugged, there may still be about 40,000 volts stored up in its cathode ray tube (CRT) that will cause great harm unless proper precautions are taken to discharge it safely.

Disc drive on mac is broken can it be fixed?
I assume when you say broken you just cannot access it. To answer your question there are a couple of things you can do but just saying it is broken, need more details. Repost your questions and give the exact symptons when you start up your computer. The easy answer is no, need to buy a new hard drive and install it, then re-install the operating system. But this means you will also lose all of your files.

You can make a image of the CD using software like nero.Then write that image to the other CD.You can then use that cd to do the repairs.
Assuming you are refering to computers, a logical partition is a division of the storage space on a physical drive. For example, the hard drive of your computer can be divided into several disks, each with its own drive letter. In PC's (not sure about this on Macs) the hard drive is historically mapped as the C: drive. It may be 120 GB in size. However, it is possible and considered best practice by some, including myself, to divide the drive into two 2 or more logical partitions. This now gives you a C: drive, a D: drive, etc. The operating systems and programs can then be installed and ran from the C: drive, and your data can be directed to the D: drive. This setup simplifies the process of backing up your data, which should be done regularly. The C: drive can be backed up whenever a major change occurs, i.e., installing a new application.

What if your PC cannot run any software?
It's bitten the dust. Try running diagnostics, then try again. If not, time for a Mac.
Is Scan all removable media before uploading it to your computer a physical security measure?
No, not really. Physical security would be locking the computer in a closet, or somehow blocking the access ports for removable media with a locked door or gate so that someone who didn't have the key wouldn't even have the option of using removable media.
Probably. Try moving it to a different folder, and see if anything bad happens. If everything runs properly, throw it out. As a general rule, anything in that folder can be deleted safely. The worst I've ever seen which could happen is that one or more programs might loose a few settings or backups.
Anyway, I'd say you should go for it.

What is the advantages of multicore processor over single core processor?
Hyperthreading is cheaper, and will produce less heat. Overall though, dual-cores are better.
