Is 1 GB bigger than 256 MB and if so why does the 256 MB memory card cost more on Amazon?
Yes, 1 GB is bigger in capacity than 256 MB. The cost of a 256 MB memory card on Amazon may be higher due to factors such as rarity, demand, brand, or specific features offered on that particular memory card.
How do you define the unit prefixes deci centi milli micro nano pico?
Deci represents 1/10, centi is 1/100, milli is 1/1000, micro is 1/1,000,000, nano is 1/1,000,000,000, and pico is 1/1,000,000,000,000. These unit prefixes are used in the metric system to denote multiples or fractions of a base unit.
How do you define the unit prefixes Tera Giga Mega kilo hecto deca?
Tera represents 10^12, giga represents 10^9, mega represents 10^6, kilo represents 10^3, hecto represents 10^2, and deca represents 10. These prefixes are used to indicate multiples of 10 in the International System of Units (SI).
A mega earthquake is an extremely powerful earthquake, typically with a magnitude of 9.0 or higher on the Richter scale. These rare but catastrophic events can cause widespread destruction, tsunamis, and loss of life in the affected area.
What is the difference between operating environment and operating system?
operating environment is the interface in which you work while operating is the platform on which your computer runs
An operating environment is an operating system with no user interface so you need to use the command prompt to do things like:
open/word/
Then the word processing program will open and you can use it.
What are non-Windows applications?
Some examples of Microsoft Windows applications are:
- Microsoft Excel
- Microsoft Internet Explorer
- Notepad
- Mozilla Firefox
Which option properly summarizes the inputs and outputs of the Calvin cycle?
1. 6 carbon dioxide molecules combine with six 5-carbon molecules forming twelve 3-carbon molecules.
2. The 12 3-carbon molecules are converted into high-energy forms.
3. 2 of the 12 3-carbon molecules are removed and the plant uses them to produce sugars, lipids, amino acids, and other compounds.
4. The 10 3-carbon molecules What_are_the_four_steps_in_the_Calvin_cycleback into six 5-carbon molecules, which combine with 6 more carbon dioxide molecules.
The process starts over.
What separates a workseet reference from a cell reference?
A cell reference points to a specific cell in a spreadsheet using its row and column labels (ex: A1). A worksheet reference refers to a different worksheet within the same spreadsheet (ex: Sheet2!A1), allowing you to pull data from or perform calculations with cells in another sheet.
What does the greek word 'atmos' mean?
The word "atmos" is the Greek translation of the word "vapor." The word "atmosphere" translates from Greek literally as "vapor sphere."
In metric system does MB equals MB?
In the metric system, MB typically refers to megabytes. It is a unit of digital information storage equivalent to 1,000,000 bytes. It is different from MB, which refers to millibars, a unit of pressure equal to one thousandth of a bar.
Prisms and gratings have different dispersive properties. Grating has a linear dispersion of wavelengths meaning the band on the focal plane varies linearly with the wavelength. Prisms are not linear, the shorter the wavelength the greater the dispersion. Thus, when a spectrum is being scanned, the dispersive device needs to rotates different amounts depending on whether it is prism or grating to focus light on the exit slit. If its grating, the slit width will need to be varied minimally; if it is a prism, the slit width will need larger changes as the dispersion gets greater.
The hertz, named after Heinrich Hertz, is a measure of frequency. It means cycles per second. In mathematical terminology its 1/s or s^-1. Giga is the same standard SI prefix meaning 10^9. So 1 gigahertz is 1,000,000,000 (cycles) per second. The FCC has a 'hole' in the frequency spectrum opened up for 'free range' use around 2.4 GHz. This is why most all modern devices you see operate in this range. A good general overview of frequencies is over at wikipedia. http://en.wikipedia.org/wiki/Hertz
Dogs can hear from what hertz to what hertz?
I researched this question and apparently: "Dogs hear high tones in particular much better than humans do. Humans can pick up an average of 20,000 acoustic vibrations per second (kHz), whereas a dog is able to perceive between 40,000 and 100,000 vibrations." Although dogs can hear pretty well compared to humans, bats can detect twice as high a pitch as dogs.
How many gigabytes is there in one terabyte?
1000 or 1024
When referring to ACTUAL SPACE on a storage device or in memory, each "unit" is 1024 of the previous unit.
1024 bytes = kilobyte
1024 kilobytes = megabyte
1024 megabytes = gigabyte
1024 gigabytes = terabyte
etc.
When selling storage devices (such as CDs or USB drives), the packaging will use a 1000 rule (same as above, but with 1000 instead of 1024), thus giving the appearance of having slightly more capacity. This is considered acceptable because in standard english, the prefixes kilo-, mega-, giga-, use the "1000 rule."
Computers use 1024 because it is the perfect power of 2 closest to 1000. Using a power of 2 is important because computers are binary (base 2) systems.
To help make this difference less ambiguous, a new set of prefixes was proposed to represent powers of 1024 (rather than 1000). They are kibi-, mebi-, gibi-, tebi-, etc.
Ernest Rutherford Did he become famous straightaway?
Ernest Rutherford discovered that atoms have a very dense nucleus, which contains protons.
Rutherford eventually coined the terms for some of the most basic principles in the field: alpha, beta, and gamma rays, the proton, the neutron, half-life, and daughter atoms
he found that all known radioactive elements emit two kinds of radiation: positively and negatively charged, or alpha and beta. He showed that every radioactive element decreases in radioactivity over a unique and regular time, or half-life, ultimately becoming stable.
He discovered the atomic nucleus and developed a http://wiki.answers.com/dp13at.htmlelof the atom that was similar to the solar system.
Rutherford's find came from a very strange experience. Everyone at that time imagined the atom as a "plum pudding." That is, it was roughly the same consistency throughout, with negatively-charged electrons scattered about in it like raisins in a pudding. As part of an experiment with x-rays in 1909, Rutherford was shooting a beam of alpha particles (or alpha rays, emitted by the radioactive element radium) at a sheet of gold foil only 1/3000 of an inch thick, and tracing the particles' paths. Most of the particles went right through the foil, which would be expected if the atoms in the gold were like a plum pudding. But every now and then, a particle bounced back as though it had hit something solid. After tracing many particles and examining the patterns, Rutherford deduced that the atom must have nearly all its mass, and positive charge, in a central nucleus about 10,000 times smaller than the atom itself. All of the negative charge was held in the electrons, which must orbit the dense nucleus like planets around the sun.
He was the New Zealand physicist who split the atom

Difference between inverted lists and multi lists?
In a Multi-list organisation an index entry points to the first data record in the
list, whereas in inverted index file an index entry has address pointers to all the
data records related to it.
•
A multi-list index has fixed length records, whereas an inverted index contains
variable length records
How many hertz are in a Playstation?
In America we use 60 hertz power. It is changed to d.c. to operate the unit. Their processors run at high frequencies. Many megahertz. You have to know which system to know that frequency.
What factors determine the quality of soap?
The quality of soap is determined by the ingredients used, ratio of fats to lye, curing time, scent, colorants, and additives like exfoliants or moisturizers. The method of production, such as hot process or cold process, can also affect the quality of the final soap product. Additionally, personal preferences and skin sensitivities play a role in determining the quality of soap for individual users.
How does MB compare to kb compare to gb?
Quite simply, a kb is 1024 b (bits), a mb is 1024 kb, a gb is 1024 mb. You may have learned in school that kilo- means a thousand, and mega- means a million. This is basically true but needs further explanation.
When referencing data, a kilobit typically is 210 (two to the tenth power), a megabit is 220, and gigabit is 230, etc., etc... Now, mB or MB (notice the caps) means megabyte which is 8 megabits; every 8 bits equals 1 byte.
As far as megabytes go, 1024 bytes = 1 Kilobyte, 1024 KB = 1 MB, 1024 MB = 1 GB, etc.
One byte can typically refer to one typed character (ASCII text is represented by 7 bits) and one bit is only a single 1 or 0, the basis of digital information.
look up "brumate" on google, its close to hiberating but for lizards. They should also be eating, every few days
6-x is a mathematical expression representing the result of subtracting x from 6.
What is a difference between broadband ISDN and narrowband ISDN?
Here are some differences between broadband ISDN and narrowband ISDN:
1) Narrowband ISDN uses 64 kb/s channel, while broadband ISDN uses 100 mb/s channels.
2) Broadband uses call relay, while narrowband uses frame relay.
3) In narrowband, ISDN information carries narrow frequency, while in broadband, ISDN uses a wide band of frequency.
