11GB = 11,000 MB
Because :
- 1TB = 1000GB
- 1GB = 1000MB
- 1MB = 1000KB
- 1KB = 1000B
What are disadvantages of computer based information systems?
the start-up costs are high
peoples knowledge and skills are reduced due to lacl of practice
unemployment is created because computers have taken over humans jobs
when there is no electricity the computer cant operate
backups need to be created to prevent data being lost through viruses, ect.
the constant staring at the computer is bad for the operator
you need to get a storage device for the memory depending on how much memory is needed
What are data capturing techniques?
D.C.Ms capture data. these are normaly inside thinner devices and can colect data, even through viruses. there is 2 levels. sharp and sting. sharp is faster but expencive.
Is there anything bigger than a terabyte?
After terrabytes, you get:
- petabytes
- exabytes
- zettabytes
- yottabytes
- Pussabytes
- Hertzbytes
- Triaobytes
- No more bytes
Each one is 1024 times bigger than the previous unit.
What is the difference between a command-line and a graphical user interface?
Command line interface is completely command controld ,flow of program controls by giving commands. so user have to familiar with commands. a novice user can not operate a CUI environment.
In Graphical user interface user interact to a visual environment like buttons, icons, images. so it is easy to use and a novice user can operate it without pre trainig.
What do you mean by clipboard?
Most GUI operating systems provide a feature called the "clipboard". Anything you copy or cut is automatically placed in the "clipboard" storage, permitting you to later paste it into some other place. This information will remain in the "clipboard" storage until you copy or cut something else (which will replace what was previously stored), permitting you to paste the same thing in many places if you want to.
The "clipboard" storage may be in different places or use different types of data structures depending on what type of information is being stored and its size (e.g. main memory, a temporary file, a temporary folder).
well, what you mean by compaction. anyway if u want to put something so large, bulky into a small box, of course u will need compaction...e.g u want to put too many dirty clothes into washing machine...this is very good example of compaction...
What does a zip drive do in a computer?
Well, depends on what you mean, .zip files (considering this is the technology section), or zips as in additions to clothing.
Zips (on a piece of clothing) will allow two sides of fabrics to be joint together, and be separted with ease. Think of them as hands on either side, when you pull the zip handle, the hands join together, and when you pull the zip handle down, they stop holding hands.
If you mean .zip files, then they're just a compressed folder, with one or more files inside. They can also be used to save space, as the file(s) being compressed will not use as much memory.
Hoped that answered your question.
What is the difference between forward slash and backward slash?
A backslash (one word, no hyphen) is used on Windows to indicate folder levels in a path to a file.
A forward slash (not one word) is used in internet addresses (and in Unix paths).
So, If you hear a website address being read out as "dot com backslash [something]" do not type that - use a forward slash (the one near the shift key; the one that leans forward)
There are 1024 gigabytes in a terabyte. So 80 × 1024 = 81920.
Retention is holding on to something and continuing to have it. Retention is often used in terms of memory, for holding on to a memory, and for schools. Schools with high retention rates keep most of their students up to graduation.
Is the computer case an input or output device?
Neither. It is simply a container for the more fragile components.
what device designates equipment that might be added to a computer system to enhance its functionality.
Cookies have been of concern for Internet privacy, since they can be used for tracking the browsing of a user. As a result, they have been subject to legislation in various countries such as the United States, as well as the European Union. Cookies have also been criticized because the identification of users they provide is not always accurate and because they can be used for network attacks. Some alternatives to cookies exist, but have their own drawbacks.
On the other hand, cookies have been subject to a number of misconceptions, mostly based on the erroneous notion that they are computer programs. In fact, cookies are simple pieces of data unable to perform any operation by themselves. In particular, they are neither spyware nor viruses, despite the detection of cookies from certain sites by many anti-spyware products.
Most modern browsers allow users to decide whether to accept cookies, but rejection makes some Web sites unusable. For example, shopping baskets implemented using cookies do not work if cookies are rejected.
More Information:
A cookie is a piece of data that can be stored in a browser's cache. If you visit a web site and then revisit it, the cookie data can be used to identify you as a return visitor. It remembers the visited pages in your system each and every time by holding data for a single web session, that is, until you close the browser data.
A cookie is a bit of electronic information that can be placed on your computer when you visit a Web site to track what you look at there, recognize you when you return, and in some cases, track where else you go on the Internet. You can set your online preferences to prohibit, limit, or let you know about "cookies" that a Web site places on your computer.
Most cookies are not bad things - you may get the impression that cookies are spying devices ("track what you view") - but for the most part they are harmless and quite useful; for example, a cookie might store your login information for a website or a forum, allowing you to visit that website/forum without logging in again each time. This is all the Wiki s cookie does.
What is data definition language?
There are four types of commands in Structured query language. One of the four type of command includes data definition language. Data definition language includes create , delete , drop command .
How many mega bytes are in sixteen giga bytes?
There are 1024 megabytes in 1 gigabyte so 1024 X 16 = 16384 megabytes in 16 gigabytes.
Is meg the same as a megabyte?
Yes and no.
A megabyte was originally 220 bytes, as a kilobyte was 210 bytes. 220 is 1,048,576, so a megabyte was 1,048,576 bytes. In the early 1980's, though, sales people for hard drive companies decided that if they arbitrarily defined a megabyte as precisely 1,000,000 bytes, it would make their hard drives seem larger and thus would make them more likely to sell.
Today we still see that same distinction. When you are buying hard drives, they are measured in "marketing megabytes, gigabytes, and terabytes," which are precisely 1,000,000 bytes, 1,000,000,000 bytes, and 1,000,000,000,000 bytes, respectively. However, when you are talking about computer memory, or when you ask the operating system (Windows, OSX, or Linux for example) about disk space, the answer you get back will always be counted in old-style megabytes / gigabytes / terabytes. And this is why a 1.5TB hard drive that you buy will only seem to have 1.2TB when you look at it in Windows after you have installed it. The number of bytes will be the same, but a true terabyte, 240 bytes, is larger than the terabytes used to define the drive size for sale.
Continuation
A megabyte is exactly 220 bytes in binary. Decimal does not align with binary bit boundaries so the decimal equivalence of binary numbers are always off counts.

Difference between external and internal memory?
Memory is usually a term that refers to RAM or Random Access Memory which is always located inside your computer.
If you are referring to Hard Drives, an internal Hard Drive is located inside of your computer and connected directly to the motherboard by a short cable. External hard drives are not mounted inside the computer's case (They will often sit on top of the tower [CPU] or on your desktop) and are typically connected via Firewire, USB, or SCSI cables. Some External hard drives require an additional AC adapter to connect to a wall outlet for power while others will revieve power through their USB cable from the host computer.
What is the modern name for ARPANET?
It was the first operating packet switching network, which realy made it the only working internt
Which code within the MEDPROS system of record depicts information for the reqirement?
The code Amber-A states that information for the requirement is present but does not meet current standard. Whereas the Code Green-G represents that a soldier meets the requirement.
Image and meaning of super computers?
Super Computers are simply that, Computers that run faster than your standard desktop computer. Super Computers usually are made of multiple connected processors and large amounts of computer memory. Some systems that have been developed have over a thousand CPUS and Huge processing capabilities about to reach into the PETA-FLOP range which basically means they can process over a 1000 trillion operations in a second. Put this in comparison with a typical home computer which can process about 2.4 billion operations a second.
What happens when a USB 1.1 device is plugged into a USB 2.0 Port?
It will work, but the data transfer rate will be much slower than if a USB 2.0 connector is used. This may not be acceptable for high data-rate applications, like high definition video.
What is the purpose of the master boot record on a hard drive?
The master boot record is the very first piece of code executed from the hard drive. The MBR is expected to simply discover the active partition on the drive, and then load and run its boot sector, but other MBRs exist, for example LILO, which loads a Linux kernel directly, and Smart Boot Manager, which allows the user to choose which partition to boot.
