Computer Hardware

Usually, yes. Older routers may depend on flash cards to store the configuration and there is a possibility that it is missing or has failed.

Most home routers will work fine after power is lost and restored.

It is 1,5 cm. long and 0,5 cm. wide port. It is a small line with a smaller usually white or black line in the left corner down and up. USB stands for Universal Serial Bus.

Go to device manager... control panel>system>hardware>device manager to check out the region code, if it is not in ur country's region, the DVD drive certainly cannot read it.

First off, the disk must be a rewritable disk.

In order to delete a song, you must erase the disk. This will erase the entire contents of the CD and require you to re-burn the disk as you want it.

A floppy drive or a CD drive or a DVD drive.

Yes, It usually depends on how much the CD storage. Cds hold more data, pictures, music and other stuff. A floppy disk can only hold kbs and mbs of files. That is less than the cds hold, and floppy disks are getting obsolete. CDs, DVDs, and USB flash drives are the latest to save things on.

when you say best im assuming fastest and most powerful, right. well the best desktops out there are mostly and mainly gaming computers. these have awesome performance, since because they're engineered for high-speed gaming. so i can guarantee these are the best for gaming, working and general tasking. but they can range up to $10, 000 (7,549.39 EUR). so the best would be the DigitalStorm Cryo-Tec or the Cyberpower Fang III Black Mamba. but you can upgrade even further BEFORE purchase. you can even double the price.

A megabyte (MB) is 1 million (1,000,000) bytes.

Roughly speaking, this means it can hold 1 million characters.

Strictly speaking, a character can take more or less than 8 bits to store, though, depending on the character and the encoding.

It is a standardized interface, meaning you don't need separate connectors for every type of device you may want to connect. It is cheap and easy to manufacture, has no pins to break, and can be safely plugged in and removed without risk of an electrical short.

It's 716.8 KB.

You can also use google as calculator, type in: 0.7 megabytes in kilobytes

But: DON'T USE ANY SHORTNAMES OR GOOGLE WON'T CALCULATE!

since there are 1024 mb in 1 gb, u do the math 1024 x 235

A tape library stores information about tape drives, magnetic strips of tape that read and write data such as those used in video cassettes and floppy discs. Tape libraries hold tape cartridges and read tap barcodes for identification.

Both, depending which fan you mean, as most computers will have several. Generally speaking the cpu fan blows air down onto the heatsink. The power supply fan blows air out. If you have separate case fans they will probably suck air in, which therefore creates airflow through the case in concert with the power supply fan.

For AC it is relatively simple from an electrical point of view. All that is required is a transformer. Even if there are other electronic solutions, unless there is good reason. Stick with the idea of a transformer since the only bad part about transformers, compared to other sophisticated electronic methods are: weight, size, stray magnetic fields but that's about all. They are robust and still very reliable and easy to use. They are available in high power units, they are easy to replace, easy to reconstruct and easy for anyone to understand it's function for later.

Transformers can step-up or down voltage depending on the ratio of windings between the primary (input) and secondary (output). If you have access to a company that wind or make transformers (Most modern city areas have such companies) One can contact them for more advice. What you will need is your primary voltage, secondary voltage, the VA

- VA is the Apparent Power which is the not the real average power since it does not include the power factor. It is only the volt(ac) x amps(ac) of the secondary. The general idea is that the power you apply on the input should be close to the power you get from the output, even though you do have some power losses (Eddie current, heat, ext.)

Then you also need to specify the type of transformer. Normally an E-Core transformer can be used. E-core is a transformer with a metal core with laminations shaped like an "E" to reduce Eddie Currents. More information can be obtained from:

http://en.wikipedia.org/wiki/Magnetic_core

If you need 24Vac for a 100W lamp then the current will be 100W/24V = 4.16A so basically you need a (24V x 4.16A) =100VA step up transformer with 12V primary and 24V secondary in a E-core style. Also note that the primary current will then increase to 8.33A since 100W/12V = 8.33A. It might even be a little bit more but never less. One cannot create energy.

Riser card

Basically hardware is the physical machine you run your software (programs) on. For example hardware includes monitors, keyboards, motherboards, cd-roms, processors, etc.

Meanwhile software are the programs you run (like notepad, Firefox, Safari, MS Word or games) and the operating system (which is a special case of software which works as a layer between the hardware and all other software).

The system unit is basically the whole computer minus the monitor and peripherals like keyboards, mice, speakers, webcams etc.

Most system units will be composed of:

· Central Processing Unit

Usually referred to as the CPU, it's the brain of the computer and its most important part as it performs the instructions of computer programs and executes the functions of the computer.

· Disk Drive

Most commonly a CD and/or DVD disk drive nowadays, though there are still computers in operation withfloppy disk drives, they are used to read externally inserted disks so as to extract data off them.

· Expansion Cards

These include graphics cards and sound cards that offer new functions and possibilities to the computerand its users. Most units will have spaces for these cards to be easily added.

· Hard Disk Drive

Otherwise known as the hard drive, this is a computer's main storage component, this is often confused with memory, or RAM.

· Random Access Memory:

Commonly known as RAM, it supplies and holds information that the CPU uses while the computer is switched on, but does not store it to permanent memory.

· Power Supply Unit

Like a battery, no juice no work! The PSU in most PCs converts the AC electricity from the mains into DC to eliminate surges that may damage the delicate infrastructure of the system unit.

· Video Card:

Otherwise known as a display adapter, they are used as a medium between the system unit and themonitor.

In this instance, you likely mean cache memory, though you could mean RAM, particularly DRAM. Cache memory, like the L1, L2, and L3 processor cache, helps to speed up operations between the CPU and RAM.

A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. PSU is a output device because it is outputting power to the rest of the device. Most personal computers can be plugged into standard electrical outlets.

Most commonly it is C drive but Hard drives can use any letter in the Alphabet (A-z. Usually when a floppy drive is available it makes itself A drive. and a dvd/cd player usually makes itself D or E. but these are automatically assigned these letters and you can change the letters of the drive (not by renaming won't work like that).
