it is arround 0.30 GB
remember 1012 KB=1 MB and 1012 MB=1GB
Hey! I don't think that is a mobile broadband related question. But, for your general information, 4g=4000mg.
What are all the types of bytes?
A bit is one unit of data, a yes or no, an on or off.
8 bits is one byte.
1024 bytes is one kilobyte
1024 kilobytes is one megabyte
1024 megabytes is one gigabyte
1024 gigabytes is one terabyte
1024 terabytes is one petabyte
1024 petabytes is one exabyte
1024 exabytes is one zettabyte
1024 zettabytes is one yottabyte
(they have just perfected the terabyte for the computer)
Gb-Gigabyte is the largest. 1 GB = 1,000,000,000 bytes 1 MB = 1,000,000bytes 1 KB = 1,000bytes 1 Byte = 1
It duplicates the frame to all Ethernet ports, except the port it came from.
A switch's MAC table is built not from destination addresses it receives, but by the source MAC addresses. So the frame is broadcast throughout the broadcast domain, until the end device with a matching MAC address responds to the broadcast, thus giving the switch a new source address to add to its MAC table.
What are the difference between deterministic system probabilistic system?
A deterministic system has a single result or set of set of results given a set of input parameters, while a probabilistic system will have results that vary.
Often, a probabilistic system (also called stochastic model, process, or system) is solved with the Monte-Carlo method. In this case, a computer program uses a pseudo random number generator to provide values of the attributes in the system that vary. The program provides an assessment of the uncertainty of results.
Typically, a large number of runs (also called trials or iterations) are made. Summary statistics may include the value that occur most frequently (mode), the mean value, and low and high range, for instance the 10% and 90% percentile. The standard deviation and histogram of results may also be part of the summary information. There is no single standard presentation as this will depend on the application.
The alternative to Monte-Carlo methods is to solve the problems using the mathematics of probability. This can be very complicated to do in some cases.
Monte Carlo methods are available in Excel as functions. For example, randbetween() for uniform discrete distribution and rand() for uniform continuous distribution from 0 to 1.
The prefix mega- means "1 million", and a byte is usually made up of 8 bits, so:
- A megabit (Mbit) is
- 1,000,000 bits
- 1,000 kilobits (kbit)
- A megabyte (MB) is
- 1,000,000 bytes (B)
- 1,000 kilobytes (kB)
- 8,000,000 bits
- 8,000 kilobits (kbit)
In some contexts, people in the computing and information technology industry use the prefix mega differently. Because digital computing is based upon a binary numbering system, mega- in many cases meant 1,048,576, while in others it meant 1,000,000.
With the increase in use of, and access to, the technology by persons with little or no education in digital computing, or experience of this historical meaning, the prefixes mega- and kilo- etc. became confusing because of their ambiguous meanings.
With the increase in storage capacities, the discrepancy between the two measurement systems became much larger and more important, and the old meaning of mega in the binary numbering system is now, therefore, formally known as megabinary.
What is the system board of the computer?
System Board is also called the Motherboard; A motherboard is the centra printed circuit board (PCB) in many modern computers and holds many of the crucial components of the system, while providing connectors for other peripherals. The motherboard is sometimes alternatively known as the main board, system board, or, on Apple computers, the logic board. It is also sometimes casually shortened to mobo.
What file extension indicates a file created by a program in bthe office 2007 suite?
Depending to the office app you are running a different extension is used. For word it is .doc for Ecel it is .xls or .xlsx. You a right-click on the file. The properties window will pop and you can see the extension there.
What is the difference between cookies and cache?
No.
Cache is a temporary storage folder(s) on your hard drive, which stores downloaded web pages and their components. For example, the HTML file, graphics, any applets. This makes reloading pages easier, as components that have not been updated on the server do not need to be downloaded again. Also, many graphics are repeated on a site from one page to the next. The cache makes this redundant usage of graphics more efficient.
A Cookie is a text file, which also resides in your cache, that has some information stored about your session on a website. It may store a key so you won't need to log in, or it may store information about what you accessed while you were there. Sometimes, so-called 3rd party cookies are placed in your cache to record some of your activity to make it easier for companies to market the most effective advertisements to you.
In IE, Firefox, and every other browser out there, you have settings to help manage cookie privacy settings, to disallow certain types of cookies. There are also settings to manage how the cache functions in general, how much storage space it maintains (once it reaches the limit it will delete the oldest stuff first), and for how long it maintains a history of those temporary files and website URLs (addresses) that you visited.

What does the file extension zip stand for?
a ZIP file
- it contains one or more files that have been compressed to reduce file size
- you have to extract the zip file to be able to see what files are in it
What is the difference between a lcd and flat screen monitor?
These names are sometimes used interchangeably. But a true flat screen monitor is a CRT(cathode ray tube) based monitor that simply has a flat screen instead of a curved one. Whereas the LCD is typically thinner and doesn't use CRT technology but (LIQUID CRYSTAL DISPLAY) technology to display pixels on the screen.
GB means giga bite while hard drive is where the computer stores data.
What four functions must exist in an information processing cycle and what happens in each?
The four computer functions are:
- data input
-data processing
-data storage and
-data output
The relationship between these and processing is that when data is entered into a computer,that is input, then the computer fetches it,decodes it executes it and results are stored in the CPU registers or even the user can choose to store to any other storage media.Therefore,the four functions of a computer are stages of information processing.
10 good netiquette principles rules?
1. Do not use all caps unless you're EMPHASIZING something. ALL CAPS ARE HARDER TO READ AND IS EQUIVALENT TO YELLING.
2. If you are experiencing high emotion, especially negative, and your reputation is on the line, like online school or job relate or something where the readers know you personally , don't submit your comment or response until you chill out. If you don't wait there is a good possibility you'll regret it later.
That's all I can think of right now :)
Who coined the term bug in relation to computer programming?
An unnamed technician working the night shift on the Harvard Mark II electromechanical computer. The machine had failed while working a problem sometime earlier and he had been troubleshooting it. He tracked the problem to a relay whose contacts would not close properly. When the relay was removed and replaced, a moth was found smashed to death in the old relay's contacts. When he made the entry in the logbook for that problem he referred to the moth as "the first computer bug" and taped the moth into the book to prove it.
When Grace Murray Hopper came in on the day shift she read the log entry and thought it would be a great story to tell.
Information required in different levels of management in organization?
Strategic management level
Tactical management level
Operational management level
Consider information required by different departments at different levels as above i.e
human resource department,
financial department,
marketing department,
production/operations department
What does computer crash mean?
"Crash" is a very subjective term when used in the context of computers. A crash can be a relatively minor problem, or it can be catastrophic. There was a time when "crash" literally meant that the read/write head of the hard drive had physically crashed into the platters that store the data rendering the hard drive useless. This is a very infrequent occurance now that hard drives are built to avoid such problems. Hard drives do still experience crashes from time to time, but usually the problem is something aside from the heads coming into contact with the storage media. Aside from hard drive crashes, there are software crashes too. Software crashes are typically easy (by comparison) to solve. Any time your computer locks up or reboots unexpectedly after giving you an error message, this can be referred to as a crash. It might not be technically accurate, but most computer people will know what you are talking about anyway.
What are names for a computer screen?
A computer screen is also known as a monitor, display, or screen. It is the electronic visual display for computers, which shows images, videos, text, and other visual information. The screen is an essential component of a computer system, allowing users to interact with the device and view output from various applications.
Differential between business system and information system?
system information means collecting information for systems or business
