 What Is Power Supply? 

POWER SUPPLY :  A power supply unit (PSU) converts main AC (alternative current ) 110-115 or 220-230 volt to low-voltage regulated DC (direct current) power for the internal components of a computer .

There are two types of power supplies existed, AC and DC power supply. Based on the electrical device's electric specifications it may use AC power or DC power.

                     ATX power supply unit

The power supply is located at the back of the computer, usually at the top. However, many more recent tower computer cases house the power supply at the bottom back of the case. In a desktop computer case (all-in-one), the power supply is located at the back left or back right.

What is Data abstraction? explain in detail ?

  What is Data abstraction? explain in detail ?  hey everyone today we will talk about what is data abstraction. Data abstraction data abstraction refers to the process of hiding irrelevant details from the user. The need of efficiency has led designed from the complex data structure to represent data in the database. here the three levels of data abstraction- 1.view level : The highest level of abstraction describe only part of the entire database. Even thought the logical level of user simple structure , complexity remains because of the variety of information stored in a large Database system do not need all this information inserts they need to access only a  part of the Database .The view level of abstraction exists to simplify their interaction with the system . The system may provide many view for the same Database.                                      2. logical level: ...

Define DBMS ? And it's applications .

  Define DBMS ? And it's applications || 2inshort Hey everyone , today we will talk about Database  management system ,this subject is very important in engineering.

Data base can have multiple tables.Database is controlled through a software called DBMS. SO what is DBMS? -DBMS is a computer software application. -DBMS interact with user , other application and Database itself to retire and analysis the data. -accept request for data from an application and instructs OS and provide specific data. -DBMS allows users  to create their own data. example - Oracle , Microsoft , SQL ,  MySQL ,  DB2 , ORION , IMS  , Foxpro , MongoDB Applications of DBMS 1.

Variable , Constant , Comments in JAVA ?

java Variable -A variable can be define as a memory location that stores an data value of a certain type. -A variable consists of a data type along with a suitable name. -Assigning a value for a variable for the first time is called initializing a variable. example int age; output first we took integer the declare its value and then print the output. Constant -The difference between a constant and a variable is that the value held by a variable can be changed throughout the problem execution . but after a constant has been initialized we can not change the value in it. example final double pi 21/7   output ERROR , because we have already declared the value of PI. Comments -Comment can be used to explain written code. -This will help a person to read and understand the code in future .  -Comments are ignored by the compiler during compilation. Whatever is written inside the comments will not be printed because it is only for understanding. instagram twitter facebook
