Differences between programming languages

-

 Programming Language: It is enabling developers to communicate with computers for  the desired tasks.

There are various programming languages that can be used for writing programs and applications

1.     Machine Language

2.     Assembly Language

3.     High- Level Language


Further the above languages has been classified into 3 generations of programming languages.

1.     first generation language

2.     second generation language

3.     third generation language

 

Machine Language

The CPU can only understand the language of ones and zeroes that is machine language

i.e. Binary stuff. Machine level language(MLL) is allowing users to write program in 0’s and 1’s

The machine language contains the bits. As we all know for computers to understand the commands provided in high-level

 languages the instructions have to be converted into machine language that comprises bits.

The compiler or interpreter conversion of a high-level language to machine language

Examples

2|2

            1-0

Binary value for 2 is 10

2|3

1-1

Binary value for 3 is 11

 

Advantages

·       It is very faster to execute the program and return the response.

·       It does not require translator. It is directly understood by the computer

·       This is very efficient when compiling program

 

Disadvantages

·       All operation codes have to remember

·       All memory address have to remember

·        Debugging of program is very difficult to finding errors in a program written in machine language is hard

 

Assembly Language

 The assembly language acts as the intermediate between machine level language and High-level language.

Assembly language is often called a low-level language as it is closer to hardware level.

A Specialized compiler known as assembler we are going to use to translate to machine level language.

Assembly language statements comprise four sections. These are mnemonic, operand, label, and comment (the last two sections are optional)

Advantages

·       The fast and efficient way of converting assembly language into machine level language

·       Easy syntax like mnemonics, label, comments and sections kind of format it is having.

·       Easy to understand

·       Easy to locate and correct errors

·       Easy to modify

·       No worries about addressing

·       Efficient than machine language

 

Disadvantages

·       It requires extra step to convert the assembly language to machine language.

·       We need to have knowledge on mnemonics like ADD,MUL,MOV. We must need a knowledge of the processor architecture and instruction set

·       many instructions are required to achieve small tasks

·       source programs tend to be larger and difficult to follow

 

High-Level Language

High-Level Language is a type of language that is designed to be easy for humans to read, write and understand.

All programming languages now days, all are high-level languages ex: C, C++, JAVA, C#, Python etc.

 

Advantages

·       Easy of use: High-level programming languages are designed to be user-friendly and easy to learn. They use simple,

·       intuitive syntax and are easier to read and understand than low-level languages

·       Portability: High-level languages are platform-independent, meaning that they can run on any operating system without modification

·       Efficient: High-level languages are designed to be more efficient than low-level languages, as they abstract hardware-specific functions and low-level details

 

Disadvantages

·       slower exec: High-level languages are generally slower than low-level languages, as they require more processing time to convert their code into machine code

·       less control: High-level languages abstract away low-level details and hardware-specific functions, making it difficult to optimize code for specific hardware or system

·       high memory usage: High-level languages require more memory than low-level languages, as they use additional functions and structures

  

Differences of Programming languages

Low-Level-assembly                                      vs                         High-Level – all languages

Compiler-c,c++,java etc.                                                            Interpreter- vb,foxfro,php,perl

Specialized features-Fortran                                                      General-purpose – all languages

Metaprogramming-LISP                                                              Non-metaprogramming- all languages

Sequential-python                                                                       Concurrent – erlang/clojure

Strongly typed-c++,c#,java                                                        Loosely typed-python

Object Oriented Language- all languages                              Object based progam-vb,php

Enforced style- Ruby                                                       non-enforced style – python

 

C

The C language is a  basic programming language and it is a very popular language, particularly used in game programming.

Pascal

Pascal language is mostly a teaching language and few industries uses this language to write the programs. This language tends to use keywords instead of symbols and braces.

Fortran

Fortran language is a number crunching language and still it is used by scientists. This language allows different sizes of variables up to the memory limit in the machine. This language is suitable for engineers, who have to calculate values with high precision.

Java

The Java language is a multi platform language that’s particularly helpful in networking. Of course, mostly this language is used on the web with Java applets. However, this language is used to design cross platform programs, Since it similar to C++ in structure and syntax

Php

The PHP language is used to design web pages and sometimes it is also used as scripting language. This language is designed to develop a rapid website.

LISP

LISP language is mostly used in computer science research and it stores all data in lists such as arrays. The syntax of list is very simple and easy to make for developers to implement structures.

C++

The C++ language has an object oriented structure which is used in large projects. The structure of object oriented also permit code to be reused many times.This language is an efficient language.

Email Sending through O365 using OAuth Protocol

-
  Microsoft Office365 EWS servers have been extended to support authorization via the industry-standard OAuth 2.0 protocol. Using OAUTH protocol, user can do authentication by Microsoft Web OAuth instead of inputting user and password directly in application Microsoft / Office 365 OAuth + EWS We can use the OAuth authentication service provided by Azure Active Directory to enable our application to connect with IMAP, POP or SMTP protocols to access Exchange Online in Office 365. To use OAuth with our application we need to register application on Azure Active directory and other steps also we need to do to get the access token back. Below are the steps   To use Microsoft/Office365 OAUTH in your application, you must create an application in  https://portal.azure.com . Sign into the Azure portal using either a work or school account or a personal Microsoft account. If your account gives you access to more than one tenant, select your account in the top right corn

IISRESET vs App Pool Recycling ?

-

 I think most IIS administrators know IISRESET command, and why they use it. One of possible reasons can be to restart IIS services to initialize web applications, or to apply some changes of applications & IIS settings .There’re just a few conditions those need your IISRESET command. In most situations, you don’t need this. I have a concern if you always run this command for applying any changes, or release system resource – memory – regularly, or frequently. Because it’s much more cost than what you really need to take – there’re side effects Recycling App Pool’ has been introduced from IIS6 in Windows2003. It’s designed to restart only application pools(=worker processes). It can be done in a command prompt(run ‘IISAPP /?’ in a command prompt for details), as well as in the IIS manager What IISRESET does? When you run IISRESET, many things will happen. In order to understand them, I think I need to show you how IIS looks like – about IIS core components. The below shows you role

Deploy .Net6.0 Web api with docker

  What is Docker? Docker is a containerization platform, meaning that it enables you to package your applications into images and run them as “containers” on any platform that can run Docker. It negates the classic: “It works on my computer” argument as Docker images contain everything needed for the app to run. Are Containers the same as Virtual Machines? They are similar, but not the same. In short: Virtual Machines provide OS Level Virtualization Containers provide App Level Virtualization This concept is depicted below: Why Would You Use it? In short you would use Docker, (and hence containers), for the following reasons: Portability.  As containers are self- contained  they can run on any platform that runs Docker, making them easy to stand up and run on a wide variety of platforms. Scalability.  With the use of additional “orchestration” you can spin up multiple container instances to support increased load. Performance.  Containers generally perform better than their VM counterp
