What does biz stand for in the end of a URL?
.biz is intended for domains used by businesses. e.g. http://www.website.bizhttp://en.wikipedia.org/wiki/.biz
There is no practical limit to how much storage space or RAM a computer can have. The amount of RAM will be dictated by the number of RAM slots and the chipset being used. Storage space is limited by the capacity of contemporary hard drives; the BIOS is capable of supporting several hundred thousand times the current size of the largest commercially available hard drive.
What are the advantages and disadvantages of parallel and serial data transmission?
big advantage of parallel transmission is the factor of speed. All else being equal, parallel transmission can increase the transfer speed by a factor of n over a serial transmission. But there is also a very significant disadvantage of parallel transmission. And that is the factor of cost. It can be proved from the fact that the parallel transmission requires 'n'
What does the keyboard shortcut notation ctrl plus esc mean?
The keyboard shortcut notation ctrl plus esc means you press the Control key concurrently with the Escape key. On a Windows PC, the Ctrl + Esc shortcut produces the Start Menu.
What the differnce between data and information?
Data is stored on a hard drive, information is stored in your brain. But, at times they are used to mean each other.
Is a mega gigabyte bigger than a gigabyte?
Yes Gigabyte is bigger than Megabyte.
Bytes are in the following order:
* Byte * KiloByte * MegaByte * GigaByte * TeraByte * PetaByte * ExaByte * ZettaByte * YottaByte For more information you can read this article from Wikipedia:
http://en.wikipedia.org/wiki/Byte Yottabyte is the biggest, 1,000,000,000,000,000,000,000,000 bytes.
none, about 0.1.
1TB = 1024GB
1GB = 1024MB
1MB = 1024kB
1kB = 1024B
so if 1024MB = 1GB, 102.4MB = 0.1GB... and 123MB is something around 102.4MB. I hope my answer is clear enough ;) sorry, i was too lazy to count it...
What was the very first graphical Web browser?
The first web browser ever written was called "WorldWideWeb", and it was created by a man named Tim Berners-Lee. While this was the very first web browser, it was not widely used, and was only available for the NeXT platform.
The first widely-used web browser was Mosaic by Marc Andreessen and Eric Bina at the NCSA at the University of Illinois. The first version was written for X-Windows on Unix, and it was later ported to other operating systems.
1 MB (megabyte) equals 1048576 bytes. In most operating systems that are 32-bit, 1 ASCII character takes up 1 byte (8 bits). However, recently, the unicode system of character representation has upped the number of bytes required to represent alphabets of all popular languages in the world.
You need to be more specific. Gb refers to a Gigabyte, which is one billion bytes (actually slightly more due to computers using base-2, but that is a different discussion). A byte is (usually) the simplest unit of storage, and can usually hold one character or number.
So a 4 Gb file will contain roughly 4 billion characters.
"4gb memory" most likely refers to a computer with four gigabytes of system RAM, which means you can have 4 Gb of data open at one time. This is different from hard disk space, which stores information while the system is powered off.
1000 Tb = 1 Pb (Petabyte)
Technically 1 Pb = 1024 Tb in the same way that:
1Tb = 1024Gb
1Gb = 1024Mb
1Mb = 1024Kb
1Kb = 1024b
7,168 megabytes (mb)-millions
7,340,032 kilobytes(kb)-thousands
7,516,192,768 bytes (GB) billions
Most common CD-Rs nowadays store 700 MB information and 800 MB CD-Rs are also widely available.
Maximum capacity of a CD-R nowadays is 860 MB.
Maximum capacity of a CD is not strictly defined, depending of production technology and the quality of the disk the maximum capacity could be pushed up to about 875 MB.
What is the main part of a computer system called?
the main part of a computer system is called central processing unit or also known as CPU
How many pages of text will fit into one megabyte of storage?
(second chronological answer dropped to bottom due to relevance)
3. A more exact answer may be found using some math:
First we'll assume that we're using 8.5x11 paper and the font Lucida Console size 10, which is a fixed font used by the latest Microsoft Notepad application. Second, we'll assume that the text is encoded using 8-bit encoding. This encoding is actually now antiquated, but it works much better for the math. New encoding methods use variable-bit encoding, so a page of one letter might be different from a page of another letter. The reason for the fixed font is that a page of i's will always be smaller than a page of W's unless the i takes the same space as W. With the previous conditions, one letter size page with 0" margins and standard spacing will have 79 lines of 102 characters each, giving 8058 characters per page.
On with the math:
8058 characters/page
8 bits per character
8 bits per byte
8058 bytes/page
1 KB = 1024 B
1 MB = 1024 KB = 1048576 B
1 GB = 1024 MB = 1048576 KB = 1073741824 B
Divide 1073741824 by 8058, and you find that one gigabyte can hold a raw
133251 Full Pages and 5266 Characters (or about 65% of another page). Note that the math gives the "raw" amount of text, which does not include any additional file information.
Hope that's definitive enough for you.
2. Well whoever wrote that last thing [Answer 1] really doesn't know what hes talking about,
if you want a lot of pages, with less storage, go find someone that will host your pictures, videos and files then just use the HTML, that way you save a lot of memory,
There are a lot of websites that host files like Mediafire and Filefront,
there is also some websites that host videos like Youtube,
I knew a few hosting services that host pictures, but I forgot most of them,
I think that ImageShack hosts them.
Anyways, once you upload them into any of those hosting services, you can copy/paste the HTML if the page supports HTML format.
This is how much space you will save:
100Mb video will be
15KB in your website if you use HTML
You will save a lot
A reply to answer 2:
The first response was a better answer to the question than the second response. The question was "how many pages of text can be stored in a gigabyte", not how many videos or pictures can be stored on a remote server.
If you have a 1GB thumb drive and zipped text pages, that would push the number up by a factor of 4 or more providing the documents were plain text.
What is a characteristic of public key cryptography?
If data is encrypted with the public key, only the private key can decrypt it
Answer Explanation: Public key encryption uses an asymmetric algorithm, which uses a public key and private key combination for the encryption and decryption process. If data is encrypted with the public key, only the private key can decrypt the data. The public key cannot decrypt a message that was encrypted with the public key. Alternatively, if data is encrypted with the private key, only the public key can decrypt the data.
A terabyte is one trillion bytes (1012 = 1,000,000,000,000 bytes) in current standard usage.
1 terabyte (TB) = 1,000 gigabytes (GB) = 1,000,000 megabytes (MB)
(There is a similar unit, the terabinary byte, or "tebibyte", which is 240 or 10244 = 1,099,511,627,776 bytes. However, this unit is never actually used, as hard drives are the only things that can hold this much, and they are always measured in powers of 10.)
1 kilobyte consists of 1024 (or 210) bytes of information. The use of 210 bytes is due to the base 2 (radix 2) numbering system used by computers.
1 gigabyte consists of 1,073,741,824 (or 230) bytes of information.
1 gigabyte, therefore, contains 1,048,576 kilobytes.
However, these values are often given by computer and software companies to mean 1 kilobyte is 1000 bytes and 1 gigabyte is 1,000,000,000 bytes. This is due to the unfamiliarity of many people with the base 2 numbering system. This also gives an edge to advertisers who sometimes mix the meanings of the quantities.
For example one company could advertise a hard drive to have 1 gigabyte of space (meaning 230) where as another may say the same hard drive has 1.073 gigabytes space which would make their product appear to be superior.
An EMOticon refers to the representation of a facial expression by using a combination of the keyboard characters to convey the intended tone or feelings of a given writer.
Ghz is an abbreviation of giga-hertz. Hertz refers to vibrations per second. 1hz is 1 vibration per second. Giga means 1,000,000,000, therefore 1ghz is 1,000,000,000 vibrations per second.
What is the following smallest unit of measurement a terabyte megabyte gigabyte or kilobyte?
A kilobyte (KB) is 1,024 bytes; however many people think of it as 1,000 bytes.
A megabyte (MB) is 1,024 kilobytes; however many people think of it as 1,000 kilobytes.
A gigabyte (GB) is 1,024 megabytes; however many people think of it as 1,000 megabytes.
A terabyte (TB) is 1,024 gigabytes; however many people think of it as 1,000 gigabytes.
A petabyte (PB) is 1,024 terabytes; however many people think of it as 1,000 terabytes.
A The definition of an exabyte (EB) is 1,024 petabytes; however in some number systems it would be 1,000 petabytes.
Therefore, the 1 kilobyte is the smallest unit.
A RAID 5 uses block -level striping with parity data distributed across all member disks. RAID 5 has achieved popularity due to its low cost of redundancy. This can be seen by comparing the number of drives needed to achieve a given capacity. RAID 1 or RAID 0+1, which yield redundancy, give only s / 2 storage capacity, where s is the sum of the capacities of n drives used. In RAID 5, the yield is . As an example, four 1TB drives can be made into a 2 TB redundant array under RAID 1 or RAID 1+0, but the same four drives can be used to build a 3 TB array under RAID 5. Although RAID 5 is commonly implemented in a disk controller, some with hardware support for parity calculations (hardware RAID cards) and some using the main system processor (motherboard based RAID controllers), it can also be done at the operating system level, e.g., using Windows Dynamic Disks or with mdam in Linux. A minimum of three disks is required for a complete RAID 5 configuration. In some implementations a degraded RAID 5 disk set can be made (three disk set of which only two are online), while mdadm supports a fully-functional (non-degraded) RAID 5 setup with two disks - which function as a slow RAID-1, but can be expanded with further volumes. In the example on the right, a read request for block A1 would be serviced by disk 0. A simultaneous read request for block B1 would have to wait, but a read request for B2 could be serviced concurrently by disk 1.
