Difference Between Active and Passive Attacks

The major difference between active and passive attacks is that in active attacks the attacker intercepts the connection and modifies the information. Whereas, in a passive attack, the attacker intercepts the transit information with the intention of reading and analyzing the information not for altering it. There are various types of threats, attacks and vulnerabilities present to corrupt and breach the system security. Security attacks are the computer attacks that compromise the security … [Read more...]

Difference Between Phishing and Spoofing

Phishing and Spoofing are the types of attacks that often used in a similar sense. The prior difference between phishing and spoofing is that in phishing the scammer tries to trick the victim with an intent to steal the confidential details resulting in financial gain. On the other hand, spoofing doesn't always involve financial gain, but the forging is similar.

Difference Between Authentication and Authorization

The authentication and authorization are used in respect of information security which enables the security on an automated information system. The terminologies are interchangeably used but are distinct. The identity of a person is assured by authentication. On the other hand, authorization checks the access list that the authenticated person has. In other words, the authorization includes the permissions that a person has given.

Difference Between Grant and Revoke

In SQL, the DCL commands are used for assigning the different authorizations to the user, these type of authorizations is known as privilege. Grant and Revoke commands are the DCL commands. The GRANT command is used for conferring the authorization to the users whereas REVOKE command is used for withdrawing the authorization. Select, insert, update and delete are some of the privileges that are included in SQL standards. Content: Grant Vs Revoke Comparison Chart Definition Key … [Read more...]

Difference Between Mirroring and Replication

Mirroring and Replication are the terms somehow related to copying of data in a DBMS. The prior difference between mirroring and replication is that mirroring refers to copy a database to another location whereas replication includes the copy of data and database objects from one database to another database. Both mirroring and replication are advantageous and increases the availability and performance of the data or database. Content: Mirroring Vs Replication Comparison Chart … [Read more...]

Difference Between Clustered and Non-clustered index

Clustered and Non-clustered index are the types of single-level ordering index where clustered index determines how the data is stored in the rows of a table. On the other hand, the non-clustered index stores the data at a single place and the indexes are stored at another place. Additionally, each table can have only one clustered index. As against, In case of a non-clustered index, a table can have multiple non-clustered indices. The indices are essentially required for the efficient … [Read more...]

Difference Between Primary key and Unique key

We have already studied different types of keys used in database and schema in the previous articles namely Difference Between Primary key and Foreign Key. In this article, we are distinguishing Primary key and Unique key. Both primary key and the unique key is used to identify a tuple uniquely and enforces uniqueness in a column or combination of a column. The essential difference between primary key and unique key is that primary key does not accept NULL values whereas NULL values are … [Read more...]

Difference Between Linear and Logistic Regression

Linear and Logistic regression are the most basic form of regression which are commonly used. The essential difference between these two is that Logistic regression is used when the dependent variable is binary in nature. In contrast, Linear regression is used when the dependent variable is continuous and nature of the regression line is linear. Regression is a technique used to predict the value of a response (dependent) variables, from one or more predictor (independent) variables, where … [Read more...]

Difference Between Classification and Regression

Classification and Regression are two major prediction problems which are usually dealt in Data mining. Predictive modelling is the technique of developing a model or function using the historic data to predict the new data. The significant difference between Classification and Regression is that classification maps the input data object to some discrete labels. On the other hand, regression maps the input data object to the continuous real values. Content: Classification Vs Regression … [Read more...]

Difference Between Schema and Instance

The Schema and Instance are the essential terms related to databases. The major difference between schema and instance lies within their definition where Schema is the formal description of the structure of database whereas Instance is the set of information currently stored in a database at a specific time. Instance changes very frequently while the schema acquires changes in a seldom manner. Content: Schema Vs Instance Comparison Chart Definition Key Differences … [Read more...]
