How many bytes is in 1 gigabyte?
well there are
1000 bytes in a kilobyte.
1000 kilobytes in a megabyte.
and 1000 megabytes in a kilobyte.
therefore i would say 3500000000 bytes = 3.5 GB
actually, there are
1024 bytes in a kilobyte
1024 kilobytes in a megabyte

What is the product of data processing?
Computer data processing is any computering process that converts datas into information or knowledge. The processing is usually assumed to be automated and running on a computer. Because datas are most useful when well-presented and actually informative, data-processing systems are often referred to as information systems to emphasize their practicality. Nevertheless, the terms are roughly synonymous, performing similar conversions; data-processing systems typically manipulate raw data into information, and likewise information systems typically take raw data as input to produce information as output.Data can be seen as a raw material, which be later coverted to information. i.e For a company that wants to produce bornvita, such company will need to make use of cocoa,which means that cocoa is the raw material for the production of borntiva, likewise data is the raw material for information. Data has to pass through a specific process before it could be changed to information, and it is called a process.
Data processing most often refers to computer processes that convert data into information or knowledge. Data processingmay also refer to: * Information processing; the change (processing) of information in any manner detectable by an observer. * Data analysis; processing data with the goal of highlighting, drawing conclusions, and supporting decision making. * Data entry done by a data entry clerk.

What are the Disadvantages of management information systems?
Disadvantages of management information system
Unemployment - While information technology may have streamlined the business process it has also crated job redundancies, downsizing and outsourcing. This means that a lot of lower and middle level jobs have been done away with causing more people to become unemployed.
Privacy - Though information technology may have made communication quicker, easier and more convenient, it has also bought along privacy issues. From cell phone signal interceptions to email hacking, people are now worried about their once private information becoming public knowledge.
Lack of job security - Industry experts believe that the internet has made job security a big issue as since technology keeps on changing with each day. This means that one has to be in a constant learning mode, if he or she wishes for their job to be secure.
Dominant culture - While information technology may have made the world a global village, it has also contributed to one culture dominating another weaker one. For example it is now argued that US influences how most young teenagers all over the world now act, dress and behave. Languages too have become overshadowed, with English becoming the primary mode of communication for business and everything else.

What is the classification of DBMS and its interfaces?
DBMS Interfaces
User-friendly interfaces provided by a DBMS may include the following. � Menu-Based interfaces for Web Clients or Browsing: These interfaces present user with lists of options, called menus, that lead the user through the formulation a request. Menus do away with the need to memorize the specific commands and syntax of a query language. Pull-down menus are a very popular technique in Web based user interfaces. They are also often used in browsing interfaces, which allows a user to look through the contents of a database. � Forms-Based Interfaces: A forms-based interface displays a form to each user. Forms are usually designed and programmed for naive users as interfaces to canned transactions. Some systems have utilities that define a form by letting the end user interactively construct a sample form on the screen. � Graphical User Interfaces: A graphical interface (GUI) typically displays a schema to the user in diagrammatic form. The user can then specify a query by manipulating diagram. In many cases, GUls utilize both menus and forms. Most GUls use a pointing device, such as a mouse, to pick certain parts of the displayed schema diagram. � Natural Language Interfaces: These interfaces accept requests written in English, Hindi or some other language and attempt to "understand" them. A natural language interface usually has its own "schema," which is similar to the database conceptual schema, as well as a dictionary of important words. � Interfaces for Parametric Users: Parametric users, such as bank tellers, often have a small set of operations that they must perform repeatedly. Systems analysts and programmers design and implement a special interface for each known class of na�ve users. Usually, a small set of abbreviated commands is included, with the goal of minimizing the number of keystrokes required for each request. For example, function keys in a terminal can be programmed to initiate the various commands. � Interfaces for the DBA. Most database systems contain privileged commands that can be used only by the DBA's staff. These include commands for creating account, setting system parameters, granting account authorization, changing a schema, and reorganizing the storage structures of a database.
Why we need conceptual design of Management Information System?
Management is a delicate system. Each decision made by management has the potential to bring big business or keep customers away.
If you do something simple like playing theme park tycoon (or any of them) you will see that all the pieces have to fit perfectly in order for the operation to run smoothly. Each decision that is made could be a potential time bomb. It all has to balance and if something is slightly out of line it could impact your business for a long period of time.
To study business gives you the tools to make the best decisions and to react quickly to the bad ones to alleviate the damage as soon as possible.
We have a bank here where I live. It is not a tiny bank because it has branches in 3 states, but neither is it a huge conglomerate. This bank decided not to take the bailout money that was being offered. The banks that did take it are trying to give it back so fast and this one small tiny bank is waving banners saying "No Bailout Money Needed". This banner reminds its customers that they are stable and their business is growing again.
What is the benefit of using a multiple-bus architecture compared to single-bus architecture?
Multiple bus structure permit several devices to work simultaneously, therefore improving the computer's speed. In addition, it isolate processor from I/O traffic and support wider variety of interfaces.
What is the evolution of data communication?

What is encapsulation and data hiding in dbms?
ODBMS stands for object oriented database management system. Encapsulation in ODBMS can be defined as binding of data together.
You often need an actual product designed to delete your data. I was giving an old computer to a friend, and I was worried about the data that I thought he might be able to retrieve later. So, I used StompSoft's DriveWasher (http://www.stompsoft.com/drivewasher.html) at the suggestion of a friend. It gave me peace of mind, and I felt I didn't have to worry about my data being viewed or retrieved. There are many products on the market, but I would recommend staying away from the freeware ones. When deleting information on a computer, the information itself is not erased straight away. The pointer to that particular information is erased so that the system no longer knows how to find it. The information remains on the media until the system writes new information over it; since there is no pointer to the information, the system believes that area of media to be blank and can write to the area. Because of this it is likely that any information "deleted" will remain on the media for a length of time dependant on the size of the media, the size of information being written to it and frequency of information being written. As mentioned above, if the information needs to be erased immediately use a specificly designed program for this purpose.
Difference between Flat File Database and Relational Database?
a flat file database allows the user to specify data attriutes for on table at a time, storing those attributes independently of an applications. a relational database take this "flat file" approach several logical step further, allowing the user to specify information about multiple tables and the relationships between those tables, and often allowing much more declaratice control over what rules the data in those tables must obey.
