What is the Spiral of Archimedes?
Not 100% sure, but I think it was Archimedes way of converting circular motion into linear motion, still used today in the form of worm gears and screw propellers. Suggest you seek verification on this.
What defines a device as a computer?
Back then, anything that could run a program. 15 years ago, anything that had some sort of 'Explorer' or 'Finder'. Today, probably anything that has a keyboard and mouse, Internet, a cd/dvd runner, and the ability to ask a question such as this one.
What is the difference between asynchronous and synchronous motors?
Synchronous AC motors run at a speed fixed by the input line frequency. Typically 60 Hz in the USA. Run a clock with the sync motor from the USA in England and it runs slow because they use 50Hz.
Asynchronous motors run at whatever free-run speed they feel like, and slow under load. A DC wound hand-drill is such a motor, runs pretty fast till you start drilling, then it slows down.
A synchronous motor will develop maximum power at its' designed speed, try to slow it down and it puts out more torque. Slow it down by overload, it doesn't create more power, it just creates more heat.
An Async motor creates highest torque at stall speed, least torque as it approaches maximum speed.
Two kinds of measurement:
Operating system calculation: "e.g Windows Microsoft" 1GB = 1024 MB
Hardware manufacturing calculation: 1GB = 1000 MB
How many minutes in 20 megabyte?
Minutes?
Megabits or Megabytes are the units of logical signals in Computers.
One Byte = 8 bits
One Kilobyte = 1024 Bytes
One Megabyte = 1024 Kilobytes
One Gigabyte = 1024 Megabytes
& so on.
If you have multiple files on the DVD, copy it to the hard drive and fit what you can on each CD marking where you left off in the files. If it's a single file, or a DVD movie or something, it's a lot more difficult. You'll need a file splitter.
Depending on your needs, it may be more than enough, adequate, or too small. It is by no means an exceptionally large capacity; even larger drive can be had for less than $100, and drives up to 1.5 TB are available commercially.
What is maximum storage capacity of a CD?
The maximum storage capacity of a CD-ROM is determined by the size and intended storage of the CD itself. The majority of CD-ROMs sold today are 74 minute and 80 minute discs, the 74 minute disc is rated to hold 650 MB but can actually hold up to 681 MB. The 80 minute disc is rated to hold 700 MB but can hold up to 737 MB.
What is the form of the signal in twisted pair cable and coxial cable?
Twisted pair wiring is a digital signal.
Coaxial cable is an analog signal.
What is the advantage and disadvantage of a synchronous counter over an asynchronous counter?
1. Easier to design
2. No propagation delay
Actually the second one is the most important reason. In designing circuits that work at high clock rates, ripples will result in errors so synchronization is very very important.
Emoticons are the little pictures that relate to a word. They come up instead of a word. For example if you typed the word smile if you had emoticons then a little picture of a smiley face would come up. They are used mostly on messaging programs such as Msn Messenger or Windows Live messenger.
Some examples
smile----> =), :)
frown =(, :(
cry:'( ='
stick your tongue out :p
How does 8086 determine wheather instruction is 8 bit or 16 bit?
based on the size of the data bus they determine whether it is a 8 bit or 16 bit . here in 8086 it has 16 bit data bus hence it is called as 16 bit microprocessor
The modem does not work list four questions to ask?
The first question to ask would be is the modem on. Next you would have to ask is the modem plugged up. If it is plugged up are the wires connected properly. Lastly you would ask have you dropped or damaged the modem accidentally in any way.
An excel cell range is the parameters you give Excel. For example, the cell range is "=$D$4:$L$28". That means the parameters are from columns D to L, rows 4 to 28.
If you want to be more specific, like a few cells and a few cells there; here is an example. "=I16:N23,E25,H28,E31" are from columns I to N, rows 16 to 23, and cells E25, H28, and E31.
Hope this explains it a little.
How many characters can be encoded into ASCII?
ASCII stands for American Standard Code for Information Interchange. It provides a means to facilitate communication on computers. It has 128 characters.
Easy question,, u can do that following numerically below,,
1 GB = 1024 MB = 1024 * 1024 KB
So 1 KB = 1/1024*1024 GB
We have to find 6000000 KB,,
6000000KB = 6000000/1024*1024 GB = 5.72GB,, thatz Answer!!
What is more a gigabyte or megabyte?
May be you are a beginner in computing things.... first let me tell you..
'Mega' stands for the power of 6
'Giga' stands for the power of 9.
However in computer terminology the following things hold good...
Kilobyte = 1024 bytes
Megabites = (1024) (1024) bytes = 1048576 bytes
Gigabytes = (1024)(1024)(1024) bytes = 1073741824.
Hope you got the answer...
The Terabyte is 1024 gigabyte and the gigabyte is 1024 megabytes, therefore a Terabyte is 1024 squared megabytes, this gives 1048576 megabytes in a single terabyte.
This is not to be confused with terabit (1000000megabits)
What has approimately 1 trillion bytes?
1,000,000,000,000 bytes is 100gb so a 128gb usb flash drive should suffice
How do you delete songs from a CD-Rom?
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.
What device is used to connect a local network to other networks?
A router is necessary for this purpose
Why might you not mind using slower memory if faster memory is available for a marginal price?
The first reason is that your computer may not be able to run at the speed of the faster memory, so there would be no benefit.
The second may be if the computer is not compatible with the faster memory.
Depending on the design of the motherboard, some computers cannot take memory faster than they are designed for. In theory, faster memory is supposed to be programmed with the settings to run at the slower speed, but the settings are not always correct, and the faster RAM may still cause a problem with the memory controller of the computer.
