What is abbreviation of BMP in computer?
BMP the file name extension for the Bitmap image file format.
How many megabytes are in three terabytes?
Here is the conversion for you because I don't fully understand the question. 8bits=1 byte, 1024 bytes=1 kilobyte, 1024 kilobyte=1 megabyte, 1024 megabytes=1 gigabyte, 1024 gigabytes=1 terabyte, and 1024 terabytes=1 petabyte. So 1024*1024=1048576 megabytes=1 terabyte making 3 megabytes=.00000286102294921875 terabytes.

How many different values can be represented by 6 bits 7 bits 8 bits and 10 bits?
To find out how many different values can represented by a certain number of bits, we can use the following formula 2n-1 and that is because the first number is always a zero.
Based on that 6 bits = 26- 1= 64-1=63
7 bits= 27-1= 127
8 bits= 28-1=255
10 bits= 210-1=1023
# of bits
1=1
2=3
3=7
4=15
5=31
6=63
7=127
8=255
9=511
10=1023
200,000
To be more accurate it is 204,800kb because it's not an even 1000kb per mb, it's actually 1024kb
What does mega byte stand for?
One million bytes.
Actually, 1,048,576 bytes.
1 kilobyte = 1024 bytes
1 megabyte = 1024 kilobytes
1024 * 1024 = 1,048,576
How many bytes is 500 GB equal to?
1 megabyte = 1,048,576
500mb x (1,048,576 bytes/1mb) = 524,288,000bytes
What is the difference between Management Information Systems and Information Systems Management?
The basic differenc between MIS and CIS is the source of the information. Management of Information Systemshandles information from all sources whether they are internal to an organization or external. Computer Information Systems is a bit more technical and strictly relate to computers and how the current organization uses the internal computer system.
What does compose mean on a email?
To compose a text message means to write it. Just like composing music... you write music if you are composing it.
What different between data and information?
Data consists of raw facts and figures. When that data is processed into sets according to context, it provides information.
For example, recording the temperature of your classroom continuously over a set period is data collection. From that data information may be derived, such as the highest, lowest, and average temperatures over that period.
A computer follows instructions (a 'program') in order to process 'data' into 'information', and can make possible the processing of vastly greater amounts of data that can be achieved efficiently otherwise.
I'll give you an example,
Data: Each student's test score is a piece of data.
Information: The class' average score or the school's average score is the information that can be concluded from the given data.
What web browser is the best in the world?
The best web browser is a matter of opinion, and many people will try and "sell" you the idea that one browser is better than another. Truthfully, there are some browsers that just plain suck, and others are considered insecure for any real web browsing. Don't pay attention to the opinion, stick to the facts, and make your own educated decision on which is the best to use.
Here's some browsers to get you started:
Mozilla Firefox: Firefox's strength comes from its ability to be customized highly, and has one of the fastest JavaScript engines on the 'net as we know it (if you don't know what JavaScript is, it's okay. It's just the code that makes pages animate menus and so on). Has a relatively long loading time, but pages load very quickly. Highly customizable so you can add new features and change its look and feel on the fly.
Google Chrome: Chrome's main design is that your screen should be used for web browsing, so it has a very minimalistic design. Having an extra half inch of screen space is pretty handy sometimes. It's very fast on the loading time, and also fast with loading pages. You can change the theme, but there's no addon functionality yet, so if it doesn't do what you want it to, you can't add it in. It natively supports Google Gears, which is used by some sites to provide a better online (and even offline!) website experience.
Apple's Safari: Safari takes a while to load, but the pages are the fastest loading of all the browsers out there (at least, as of right now). It has an iTunes-like interface for browsing your history, and provides thumbnails for every website in your history, which is pretty impressive. No addons, but has some nice customization features not found in other browsers.
Opera: Originally a "pay to play" browser, this freebie browser has a medium-length load time, faster than Firefox, but not as fast as some of the others. It loads pages decently fast (used to be the fastest before Apple stepped up their game). That being said, it has many cool features. A "magic wand" feature that you can configure with your personal identity-- it can fill out most forms for you in a single keystroke. Not just a username and password, but an entire form with your name, email address, phone number, mailing address, and more... but only if you want it to. Also, the only browser I've seen that shows thumbnails when you hover over tabs, voice recognition as an option, and built-in Mouse Gestures, which lets you perform common browser features such as going back and forth between pages with a simple mouse-click. Finally, it uses some HTML technologies not found on other browsers, which is nice.
Internet Explorer: The fastest loading of all the browsers, it's often slow to load pages and new tabs. Commonly faulted for having the most open security exploits, it happens to be a good browser for day-to-day use. It doesn't have addons, except for browser bars, but has some interesting Microsoft-only technology. Web Slices, for example, allow you to take an item on eBay, and add it to your browser. You can watch the bids on the item as the timer ticks down. It does require that the page supports Web Slices, but several major developers have already picked up on the idea. It also has Accelerators, which allow users to make quick actions with data on a page. If you like a quote, highlight, choose Post to Blog, and there you go, it's done. As long as you keep the security on it to a high level, it's actually a decent browser to use.
Flock: Based on some of the other Mozilla browsers, Flock loads decently fast, but its claim to fame is social networking. If you are an avid blogger, if you use services like Facebook and MySpace, you'll want to at least give this browser a second glance. It can keep you logged in to all your favorite services, and provides a unique sidebar that shows you updates from your friends without having to use an entire window or even tab. It runs on par with Firefox, but the bonus features are nice if you have a use for them. Also, last time I checked, it had the ability to load all of the Firefox addons as its' own as well, so it's even easier for Firefox users to try it out.
The entire point of this answer is that, there is no one right answer. Some people like IE the best, some like Opera the best, while others swear by Firefox. And there's others out there not even listed here. Gone are the days of having only one or two choices for your web surfing experience. Take a peek at each browser (go on, they're all in the 10-20mb range), and pick what works best for you. Spend one day with each browser, see where it takes you.
May the best browser win.
What is the Windows keyboard shortcut to shut down Windows when no applications are loaded?
There are two answers:
You can use Alt+F4. Then it will show the option's box - log off/restart/shut down. using up/down arrows, select one. press "Enter".
Or, you could:
Press the windows key on the keyword (between the alt and ctrl on the bottom left)
Press U
Press U
Alt + F4
Memory cache is referred to as SRAM?
Yes it is true that memory caching is a method used to store data or programs in SRAM for quick retrieval. The North Bridge is the faster end of the hub that contains the graphics and memory controller.
The stages of system analysis are scope definition, problem analysis, requirements analysis, logical design and decision analysis. System analysis is defined as the study of sets of a system to find ways of improving its efficiency.
Difference between DOS and Linux file system?
There are a few differences.
1. In Windows, each seperate filesystem is accessed independently of the other through drive letters. In Linux, each seperate filesystem gets mounted and integrated into one unified filesystem tree.
2. Windows only really supports a few filesystems, primarily NTFS. Linux supports a wide range of filesystems: ext2, ext3, ext4, btrfs, zfs, jfs, reiserfs, ntfs, etc.
3. Both are capable of supporting loadable filesystem drivers, but Linux has better support for it by far. Also, Linuxhas a filesystem driver called "FUSE" which allows filesystems to be made available through userspace.
4. Linux makes use of pseudofilesystems. Windows doesn't. Because Linux follows the Unix philosophy of everything being a file, Linux can abstract a great deal of things into filesystems, and already does for /dev, /proc, and /sys.
5. Linux core file permissions are more simple but usually more effective than Windows'. The vanilla Linux permissions have three contexts: User, Group, and Others, with three permissions for each: Read, write, and execute. Furthere, three special permissions applied to the file globally, sticky, suid, and guid.
6. Linux has full linking capability, both hard and soft links. Windows has a pretty limted linking capability, bt most users will end up using the "shortcuts" system instead, which is not so capable. With Linux, soft links behave for all intents and purposes as if they *are* the file or directory they point to, meaning even most software apps will make use of them as if they are the real thing, something that cannot be said for Windows shortcuts, which for the most part are almost completely ignored by most software. Finally, a note on hard links: Hard links are different from soft links in that they actually ARE the file itself. Hard links are an actual inode (Filesystem metadata.) reference to the file data itself, virtually indistinguishible from the "original" file. This is not the same as a copy, as a copy actually is that, a copy, where the data is actually duplicated. In this case it quite literally is the file or directing existing in multiple places at the same time on the filesystem. The disadvantage is that hard links do not work across filesystems, largely because an inode cannot really know the contents of another filesystem without a lot of outside help, such as RAID.
7. Windows fragments a lot. Linux hardly fragments unless there's chronic space problems or lots of saving and deleting. This is largely based on how the two operating systems format their filesystems. For the most part, no OS really has the same sort of control over where any data is physically placed on a disk, as the hard disk controller itself, but an OS can influence where the data is placed based on the data structures they specify to the hard disk controller. This problem is far less pronounced in Windows as it used to be, however.
8. Windows doesn't provide any real native loop interfacing with virtual media, such as disk images. Linux does, in the "loop" driver, allowing one to store an entire filesystem in a normal file and mount it as if it were a disk. Windows has third party utilities that can do this, but most of them only support ISO images. This allows Linux to give users handy ways to encrypt and store data in ways Windows can't even begin to approach.
9. Finally, swap space: Windows and Linux approach this in fundamentally different ways. Windows uses a file to store swap data right on the system partition, allowing it to grow and shrink, contributing to overall fragmentation. Linux, on the other hand, Makes an entire partition for swap data. Though in many cases with RAM being as large as it is today and the level in which Linux kees its memory usage down many Linux users don't use swap at all. Linux *can* deploy a swap file like Windows using the loop interface mentioned above, but it's really just better to set aside about 5 GiB of your hard disk to swap (Hard disks are large and cheap, so dedicated swap space is hardly costly to most users.
Which is a single user operating system?
A single-user operating system is a type of operating system (OS) that is developed and intended for use on a computer or similar machine that will only have a single user at any given time. This is the most common type of OS used on a home computer, as well as on computers in offices and other work environments. There are two general types of single-user operating system: single task and multitasking systems. Though a single-user operating system can be connected to other systems through a network, it is still truly only used by a single person and is different than a multi-user OS. A single-user operating system that is a single task system is developed for use with a computer or electronic device that will only run one application at a time. This type of OS is typically used on devices such as wireless phones and two-way messaging devices. A single task, single-user operating system can only run one program or application at a time, and so is not as useful for a computer or other device intended to run multiple programs at once.
What is the function of the USB ports in a computer?
Universal Serial Bus, is a device system designed for the accessories of the computer system, it allows you to hot swap any devices that is designed for the port. Some of these devices include: Keyboard, Mouse, Game Controllers, Lights, Fans and a slew of other things.
What are the characteristics of relational database management system?
characteristic of relational data base system
There are a number of characteristics that distinguish the database approach with the file-based approach. In this section, we describe in detail some of those important characteristics.
Self-Describing Nature of a Database System : Database System contains not only the database itself but also the descriptions of data structure and constraints (meta-data). These information is used by the DBMS software or database users if needed. This separation makes database system totally different from traditional file-based sytem in which data definition is a part of application programs
Insulation between Program and Data : In the filed base sytem, the structure of the data files is defined in the application programs so if user want to change the structure of a file, all the programs access to that files might need to be changed. On the other hand, in database approach, data structure is stored in the system catalog not in the programs so such changes might not occurs.
Support multiple views of data: A view is a subset of the database which is defined and dedicated for particular users of the system. Multiple users in the system might have different views of the system. Each view might contains only the interested data of an user or a group of user.
Sharing of data and Multiuser system: A multiuser database system must allow multiple users access the database at the same time. As the result, the multiuser DBMS must have concurrency control strategies to ensure that several user try to access the same data item at a time do so in the manner so that the data always be correct.
What is 512000 megabytes in gigabytes?
a gigabyte equals 1000 megabytes. so 512000/1000=512 gigabytes.
Not exactly. Everything to do with computer memory is measured in powers of 2. A Kilobyte is 1,024 bytes, A Megabyte is 1,024 kilobytes, and A Gigabyte is 1,024 megabytes = 230 bytes
How many bytes does human memory have?
Estimating the storage capacity of human memory is challenging, but some scientists suggest it could be around 2.5 petabytes, or about 2.5 million megabytes. This estimate is based on the number of neurons and synaptic connections in the brain, which store information. However, human memory is not directly comparable to digital storage, as it involves complex processes of encoding, retrieval, and forgetting. Thus, the exact byte equivalence remains largely theoretical.
