Web Developer must know -File Sharing Protocol Filesystem- NFS, SMB, AFP and FTP

 

 

File sharing protocols: Application Layer
Protocol	Description
SMB (Server Message Block)	Supported by Microsoft Windows computers and sometimes by Mac OS X protocol is enabled by default. It is sometimes referred to as the CIFS (Common Internet File Service) file-sharing protocol.   SMB uses TCP/IP.
NFS (Network File Service)	Linux and Unix computers use NFS. Mac OS X users can access NFS shared folders through console shell access. UDP and TCP and NFS v4 over TCP.
AFP (Apple File Protocol)	Mac OS X computers use AFP.
FTP (File Transfer Protocol) and FTPS (FTP with SSL encryption)	Many public file upload and download sites use FTP.
Rsync	Fast file-transfer protocol that uses a delta-transfer algorithm that sends only the differences between the source file and the existing file.
HTTP (Hypertext Transfer Protocol and HTTPS (HTTP with SSL encryption)	Used on the World Wide Web.
SSH( Secure Socket Shell	Remote access to machine vis SSH connection.

History Browser War

{ IE vs Netscape }

In the year 1999 Browser War erupts between Microsoft IE and Netscape Navigator Browser .

Many developers had no choice but to tailor their websites for one browser or the other. Of course, it was ultimately the users that suffered.

With the release of Internet Explorer 3.0, Microsoft dropped the hammer. They included this version, for free, bundled right into the Windows ’95 operating system.

Netscape pricing model fell apart

In November of 1998, Netscape was sold to AOL for $4.2 billion- The end of pioneer.

Multithreaded operations with the Task Parallel Library

 Async Vs Parallel Programming

Asynchronous Programming

• Task Runs asynchronously however it is dependent on task results and wait for task to get completed. For e.g Operation that calculated Average on large set of data. Now these calculations will happen asynchronously while it wait for complete all its task.
• Async Task run or executes on SINGLE thread
• It is wait dependent

Parallel Task Programming

Threads are the virtual components or codes, which divides the physical core of a CPU into virtual multiple cores. A single CPU core can have up-to 2 threads per core.

CPU is dual core (i.e., 2 cores) it will have 4 threads. And if a CPU is Octal core (i.e., 8 core) it will have 16 threads and vice-versa.

     CPU----1 Core--------2 Threads

The thread is created by a process. Every time you open an application, it itself creates a thread which will handle all the tasks of that specific application. Like-wise the more application you open more threads will be created.

For eg. Two thread you can listen to music at the same time you can update a powerpoint presentation.

Get Started with Blazor.net web flow project solution

 Blazor.net web flow and project details are given below. Before you start Blazor.Net it is important to understand the basic file system and flow of execution.

.Net 5.0 Project Dependencies are now simplified

If you come from a background of .Net framework , you must see hugh improvement and shifts in how we managed project depencies. Let us have a close look.

It is now neatly categorised

• PROJECTS folder dependencies within solution
• Nuget package is bundled under PACKAGES
• Framework reference such as .net core or .net 5 is bundled in FRAMEWORKS folder.

Next time you open Visual studio 2019 solution with Blazor , Xamarin or MVC project you should have figure out this feature. 

Dot Net 5.0 is not just the next version of Dot Net Core, it is more than that
