A stored attribute is a data field that is physically saved in the database, representing actual information about an entity, such as a person's age or name. In contrast, a derived attribute is not stored directly but is calculated or derived from other stored attributes, like calculating a person's age from their birthdate. Stored attributes provide direct access to data, while derived attributes offer insights based on existing information.

What is the difference between division and modulus operator?
Divison is a divison of two integers and result is stored in some where. where as Modulus is remainder is stored in some where. EX:DIVISION 45/4=11 MODULUS 45%4=1
Difference between a local procedure and stored procedure?
local procedure wont store in database. Stored procedure store in database permanently and we can use it whenever we require. Other program also can use this stored procedure. And the transaction of stored procedure take care by DBA. But the local procedure transaction is take care by manually only
Differentiate between Direct Access and Sequential Access methods?
the difference between them is that direct access, such as a DVD allows you to go directly to a specific piece of data using an index, whereas sequential access is when data is chronologically stored on a VCR tape or Magnetic tape, you must go through all the data before you reach the data your looking for.
What is a fundamental difference between data and programs?
A fundamental difference between data and programs lies in their roles and functions. Data consists of information or values that can be processed, stored, and analyzed, while programs are sets of instructions that tell a computer how to manipulate that data. In essence, data serves as the input or content, whereas programs define the logic and operations to be performed on that input. This distinction underpins the functionality of computer systems, where data and programs work together to achieve desired outcomes.
What does each column in a database represent?

What is the relationship between the potential difference across a capacitor and the amount of charge stored on it?
The potential difference across a capacitor is directly proportional to the amount of charge stored on it. This means that as the potential difference increases, the amount of charge stored on the capacitor also increases.
Suppose a parallel plate capacitor (with capacitance) is connected to a battery, what is the relationship between the charge stored on the capacitor and the potential difference across its plates?
The relationship between the charge stored on a capacitor and the potential difference across its plates is that the charge stored on the capacitor is directly proportional to the potential difference across its plates. This relationship is described by the formula Q CV, where Q is the charge stored on the capacitor, C is the capacitance of the capacitor, and V is the potential difference across the plates.

What is the difference between struct and union in c file management?
The main difference is in how the data structures are stored. In a union, all of the elements are stored in one location. A structure stores each of its elements in a separate memory location.

What is the difference between bridge mode and router mode on an ADSL router?
The basis difference between bridge and router mode in a Modem is to identify where does the user creditials are stored. In router mode, they are stored in the modem/router itself. In Bridge mode, creditials are stored on a pc and you would need to click on connection icon / connection to establish the connection KK@Melbourne
