Relocatable VS Non- Relocatable Programming
A relocatable program may use many part of memory address in run time of a program. This type of program uses relative addressing and its address space can be change at run as requirement.
A Non-Relocatable program runs in fix address space. Location of program data fix at the time of compilation.

Byte Code
" Middle level output of a compiler "
High level languages like (C,C++,Java,C#) are easy to code , Programmer write code using a text editor or IDE provide by related language compiler called source code.
Source code cannot run direct by computer it need to be transform into machine language by compiler.
Difference between Syntax and Semantic
| Syntax | Symantic |
|---|---|
| Syntax is related to language grammar, i.e. in C language every statement is terminated by semicolon (;) if you missed it, then compiler will generate a syntax error (statement is missing) | Semantic is related to meaning which cannot be detected by the compiler. Wrong implementation of a logic will not produce expected output. For example, we know when the product of a number has to calculate then we must use (*) if by mistake or any other reason (+) are there then it is semantic bug. |

The RSA algorithm is an example of asymmetric cryptography, which is widely used in worldwide for securing sensitive while sending insecure medium like the internet.
RSA was first described in 1977 by Ron Rivest, Adi Shamir and Leonard Adleman of the Massachusetts Institute of Technology. Two types of keys are used, public and private. Private is secrete key used by the owner or receiver. Data can be encrypted using a public or private key, but decryption can be done only with the private key.

Form Validation,File Type Validation : Javascript
It’s a good practice to validate your form using script before sending because it’s giving quick response than server validity. But keep in mind server validation is always necessary because JavaScript may be disabled by the user. So server validation is mandatory. I am presenting complete code for validating a check box, textbox and file. My main focus is on file validating because file validation is complicated task for new web developers So this will help you a lot.

Difference between Top-Down and Bottom- Up Programming
Top Down Programming
Top down approach is used by procedure oriented language like C. In this concern A problem is solved by the top level wise i.e. A main function is created which draw a sketch that how will our program be started and then find out the low level modules further. The problem is divided into the sub modules and implemented each coding separately, which called and control by the main function. Top down approach is no longer popular today.Bottom Up Programming
Bottom up approach is used by the object oriented language like C++, Java, C#, VB.Net, etc. In this approach design starts with bottom level , by inside of a class. Ones A class is implemented, then object of that class is created. A main function is generally also used here like procedure oriented languages as a starting point, but it’s used only to call the class functions.

Symmetric Encryption
" Data format changed using a secret key and can be decrypted only with this secret key receiver must have the secret key for decrypt message. Symmetric Encryption. "
Symmetric encryption is the oldest and best-known technique. A secret key, which can be a number, a word, or just a string of random letters, is applied to the text of a message to change the content in a particular way. This might be as simple as shifting each letter by a number of places in the alphabet. As long as both sender and recipient know the secret key,
Bridge : Computer Network
" Bridge is May be a combination of hardware and software or individual is used to connect two segment of same LAN (Same IP Domain). Bridge decreases the network traffic and also used to connect two different platform LANs like UNIX and Windows. "
A network bridge is software or hardware that connects two or more networks so that they can communicate.
People with home or small office networks generally use a bridge when they have different types of networks but they want to exchange information or share files among all of the computers on those networks.
Here's an example. Let's say you have two networks: in one, the computers are connected with cables; and in the other, the computers are connected using wireless technology. The wired computers can only communicate with other wired computers, and the wireless computers can only communicate with other wireless computers. With a network bridge, all of the computers can communicate with each other.

Var_name= mysqli_fetch_assoc([connection_object]->query(SQL Statement))
mysqli_fetch_assoc returns one dimensional array so use can use table column name as index
mysqli_fetch_assoc returns one dimensional array so use can use table column name as index
