What are some important considerations for data backups?
When you are trying to create a backup system you should consider the following:
- What needs to be backed up
- How often it needs to be backed up
- How much space is necessary to back it up
- Where the backup should be stored
- How the backed up data should be encrypted and lastly;
- Who should have access to the backup.
2 components that must utilize the same front side bus speed?
Two components that must use the same front side bus speed are the processor and the system board. However, modern computer system boards support a range of FSB speeds and hence a range of processors.
What is the difference between a CD and DVD drive?
A CD drive is an optical drive (a piece of hardware that reads Compact Discs).
A DVD drive is an optical drive (a piece of hardware that reads DVD Discs).
There are lots of optical drives that can read both DVDs and CDs, some can even 'burn' information onto blank discs.

Smart card is generally referred to a card bearing an integrated circuit (IC). Typically, the IC has an operating system of its own and runs an application on it for storing the user data. A terminal with smart card reader is generally used for reading & writing the IC.
What is interrupt in architecture?
program interrupt is transfer program control from currently running program to a service program depends on internal or external generated request
after execution of service program, program control will be returned to original program
What type of electrical current does a computer need to function?
All computers, and electronic devices for that matter, require a direct current (DC). Any electricity coming from a wall socket is what's called AC or an alternating current because it oscillates back and forth very rapidly. Computers require a very constant and steady stream of electricity and so it must convert the power from an outlet from AC to DC before it can be used. That's why there are capacitors on the motherboard to steady and even out power while changing it from AC to DC.
How A power supply you suspect is faulty is to replace it?
It may be time for a new power supply if your computer keeps shutting down at random times, or gets hot very quickly, you may want to act fast in order to keep from your computer crashing.
Can the acer aspire one have windows 7?
Or rather, can windows XP/Vista be run on a Acer aspire one machine. Yes it can.
There are several guides to find, explaining how to install XP/Vista via USB pendrive to the Acer aspire one series. Also on the Acer website the drivers for the Acer series have been made available.

What device displays computer output on a screen?
If you are talking about the thing that looks like a tv, its called a monitor. If you are talking about something else, you will need to be more specific
AMD stands for Advanced Micro Devices and is a manufacturer of semiconductor products. Its main products include microprocessors, motherboard chipsets, embedded processors and graphics processors for servers, workstations and personal computers, and processor technologies for handheld devices, digital television, and game consoles.
What does bus in bus cable stand for?
It doesn't stand for anything. Bus refers to a number of things but generally it's a pathway between a resource and a device on a computer, which is presumably why it's called a bus (even though the transferal bears no resemblance to the route of an 'omnibus') http://www.answers.com/bus?cat=technology
Where do expansion cards plug into?
That is difficult to say without knowing the cards intended use. Some cards plug into expansion slots on motherboards. Some plug into risers. Some expansion cards are actually daughter cards that plug into another card.

What is the size of a mainframe?
The first mainframes were large enough to fill an entire room. The mainframes today created by IBM are about the size of your household refrigerator.
What is a reason for using input devices?
You need input devices because with out them you would not be able to communicate or input data into a computer or machine. Imagine it this way. with out a key board how would I type this answer. I couldn't with out using a form of input such as speech recognition or the standard keyboard.
1660 megawatts how many watts?
mega- means time 10^6, in other words, million
so 1660 Megawatts is the same as 1660 million watts is the same as 1.66 billion watts is the same as 1.66*10^9 watts.
What is meant by volatile and non-volatile memory?
non volatile memory is memory that doesn't wipe after the computer shuts down e.g: Flash memory.
What components and cables are needed to connect 4 computers?
for connecting 4 computers you would need a "hub"(en.wikipedia.org/wiki/Network_hub), and a cat5 cable to connect each computer to the "hub". each computer would also need a "network card"(en.wikipedia.org/wiki/Network_card), alot of modern computers come with a network card integrated so you may not need to purchase it separately.
Why should you upgrade your computer?
Simply because the speed technology updates these days could leave your computer floundering with old components. In general it would be cheaper to upgrade things like the RAM, hard-drive or video card. However - if you needed to upgrade lots of components, it's likely to be cheaper to buy a new machine.
The voltage which charges the capacitor can only hold peak voltage. It can only use the energy stored in the capacitor if it uses faster than the power supply can replenish it causes a ripple.
What are the advantages of RAID 0?
Some of the advantages of RAID O is that it is a very simple design, it's easy to implement, I/O performance is greatly improved and the data is broken down into blocks which means each block is written to a separate disk drive.
What is the purpose of a heat sink in a computer?
Heat sinks are very important components in computers. The purpose of heat sinks in computers is to keep the computer from overheating. The heat sink removes heat from the processor, keeping the processor cool.
How many kilobytes in 10 gigabytes?
10 GB = 1024 x 10 Megabytes
10240 Megabytes = 10240 x 1024 KB = 10485760
Can you use an ultra160 SCSI drive with a ultra320 SCSI controller?
Yes you can.
They will work fine. These statements "they are not designed to do this and would not do it well" WRONG and "Performance would be terrible and the drives would fail much sooner" also WRONG. U320 drives are backwards compatible and should work without issue on a U160 controller, the performance will be the same as a U160 drive and will not affect the drive's MTBF.
The drives will work fine !! The performance of the drives is NOT impacted at all --> they still rotate at the same speed; the seek times aren't any different; etc. The ONLY difference is that the interface speed is different (Ultra 160 vs Ultra 320). ... and it certainly has NO impact on the reliability of the drives !! [r.e. "... the drives would fail much sooner ..."].
... in fact, unless you're using an array which could support a sustained transfer rate higher than Ultra 160 speeds, the ONLY time there would be any difference in performance (compared to an Ultra 320 controller) will be in transfers to/from the drive's buffers => a very low % of disk operations.
Bottom line: Buy the disks you listed. They'll work just fine :-)
