There are many ways to transfer data and send messages on the internet. While transferring data or forwarding the message, different processes take place; the process in which the messages are forwarded to the server is identified from the port number. Many port numbers are used for networking, such as HTTP port, DNS port, and FTP port. 

The port number usually consists of 16-bit numbers. It plays a role in identifying and tracking the information, which helps determine the type of information and the devices used to transfer it. 

In simple words, there is a port on every networking device, and each port has a number that indicates the function it will perform and the protocol it will follow.

The port checker determines if a specific port is open and available for use on a target host. This is useful for network administrators, system administrators, and security professionals to check the status of various services running on a server, ensure that firewall configurations are correct, troubleshoot network connectivity issues, and perform security audits. By checking the status of a port, one can determine if a service is available and if it is, what type of service it is running.

Let’s move forward to discuss the details of different port numbers. 

Different Types of Port Numbers and Their Uses

There are around 65535 port numbers in the network. However, there are only a few of them which are practically used. Port numbers are divided into three types: restricted, registerable, and private.

Restricted Ports: Restricted ports are those reserved by prominent companies and only accessible to employees. There are 1023 restricted ports in the range of 0 – 1023. Several services run on these restricted ports, including SQL and Apple QuickTime.

Registerable Ports: These ports can be registered by multiple companies, especially software houses, for their software. The range of these ports is from 1024 to 49151.

Dynamic Ports/Private Ports: These ports are available for anyone. This means anyone can use these ports for their use. The range of dynamic ports is from 49152 to 65535.

Here are a few port numbers with their uses and specific assigned names used in our daily and regular life.

Port 20 / Port 21 – File Transfer Protocol (FTP)

The Port 20 and 21 – File Transfer protocols share files between multiple people. It uses two separate protocols to make things easy to share the files between the client and a server. 

It is widely used all over the world to share back and forth the same file between a client and a server or the cloud.

File Transfer Protocol

Port 25 – Simple Mail Transfer Protocol (SMTP)

The port 25 – Simple Mail transfer protocol is used for sending emails. For emails sent to another person, port 25 is in use for sending the email regardless of what email platform you use. 

Port 25 – SMTP helped the world to get closer and gave a reliable source to the world, which helps in sending all kinds of important messages worldwide. An SMTP tester is a tool used to verify the configuration and operation of an SMTP (Simple Mail Transfer Protocol) server.

Port 53 – Domain Name System (DNS)

The Port 53 – Domain Name System is usually used as a compiler but on the internet. The DNS port helps to make all the human-readable text in the IP address to make it a readable machine. 

The port 53 – DNS port made things easy for users to find the right website. The user doesn’t have to write a long IP Address and try multiple IP Addresses to find and open the right website or application. But just writing a domain name can help in opening the right website.

Port 80 – Hypertext Transfer Protocol (HTTP)

The Port 80 – Hyper Text Transfer Protocol helps in the World-Wide Web. When you enter a domain in the browser and hit enter to open the web page. The requests from the browser are sent to the server for display, and as a result, the server sends the request to the browser for display. da

The Port 80 – HTTP has played a big role in browsers and websites. It made it easy for normal people to make their business visible on the internet through the World Wide Web.

Port 443 – Hypertext Transfer Protocol Secure (HTTPS)

The Port 443 – Hyper Text Transfer Protocol Secure works like the Port 80 – Hyper Text Transfer Protocol. Only the difference is that it is more secure and safe when it comes to data. The World Wide Web is also used to ensure the security of data transferred from browser to server or server to browser.

The Port 443 – Hyper Text Transfer Protocol Secure also connects with other ports like port 20, port 21, port 25, and more. It means you can share your personal information like credit card info, personal emails, or other private data through a secure port. 

Port 3389 – Remote Desktop Protocol (RDP)

The Port 3389 – Remote Desktop Protocol helps control your desktop device remotely from another device. This helps you to access and control the desktop even if you are farther from it.

The Port 3389 – Remote Desktop Protocol also helps access a desktop of a completely random IP in your system. This allows the user to use multiple desktops of multiple IPs in the same system.

Conclusion

Port numbers play a crucial role in the functioning of computer networks and the internet. They provide a way for different applications and services to communicate with each other over the network by identifying a unique destination for each communication. Port numbers are unique 16-bit values assigned to specific services and applications, making it possible for network communication to be organized and efficient. Understanding port numbers is important for network administrators, security professionals, and individuals looking to secure their networks, as it helps in identifying potential security vulnerabilities and ensuring compliance with various security standards and regulations.

Do you create music and utilize SoundCloud? The reason you put your songs out there is that you want to be heard by a lot of people. Increased plays and followers’ equal success. It’s important in increasing the findability of your music and giving the impression of a strong, popular profile. The more plays you get, the higher the tendency of new listeners to actually check you out.

This is quite a big challenge for new artists. Every day, millions of songs are put online. That may make it hard to get noticed among all those people. Sometimes, using a smart service can give you a quick boost. Some term this the “SoundCloud Fast Lane.”

Why a Quick Boost Can Help

In that case, when a song has only a few plays, it usually gets passed by. They think it is probably not good, but when it has many plays, people get curious. They stop to listen to it. A fast boost of plays acts like a starting push for making your music look popular right away.

This quick push leads to what we call “social proof.” “Social proof” means that people believe things that other people enjoy. You must want to listen to that song if it has 10,000 plays. Such a thing would help in bringing to your song real, organic listeners. It can make your song appear high in the search results. It helps more real people find your music.

Choosing the Right Service

If you choose to get a boost, you have to choose wisely. You have to employ the use of a service that is safe and reliable. Search for firms that provide real-looking plays. Keep off services that deploy very fake accounts or bots. SoundCloud can spot such bad techniques from afar. If SoundCloud sees that you are faking plays, they might remove them. In the worst cases, they may actually take down your song.

One that is reputable will send them slower. These plays will be coming from accounts that appear to be natural. They should be delivered naturally over several days. This helps make the build-up seem authentic to the SoundCloud system. Always be on the lookout for a seller who has good reviews from other musicians.

How Plays Help Get Followers

More plays often directly translate to more followers. Think about what a person who has never used this before goes through. If someone sees that a song has a lot of plays and listens to it and likes it, they will hit “Follow” to hear your future music.

The number of plays helps people trust your music. The number of followers shows your long-term success. It shows you have a dedicated fan base. Having more followers is really important when trying to get recognition from music labels. It simply means that people actually do care about what you are making.

Important Things to Remember:

Advertisement

One fast boost is just a beginning. You can’t rely on it alone. Keep making great songs. The quality of your audio is the most important thing. If your song isn’t good, then boosted plays will not bring real fans. Listeners will listen once and then leave. You have to be active on SoundCloud, too. Reply to comments, speak with your listeners, and share your music on other social media sites.

A quick play boost is just a tool; it is there to help your good music reach more people faster. It opens the door, but your music must keep the door open. Use this fast lane to get noticed; then, let your good songs do the rest of the hard work. This is the most straightforward route to bigger success on SoundCloud.

Explained – Why Should You Migrate Databases From Oracle to SQL Server

Published

Migrate Databases From Oracle to SQL Server
Click to rate this post!
[Total: 0 Average: 0]

The Oracle Database Management System (DBMS) has been the mainstay of data-driven organizations around the world for more than 40 years now. So, is it relevant to ask whether businesses should migrate databases from Oracle to SQL Server? If yes, what benefits does this activity bring to the table?

In this post, you will learn about this form of database migration as well as the process of doing so. 

Taking an overall view of the current business environment, it is seen that organizations, regardless of their size and scale, are largely data-driven, with massive volumes of data being generated every day. This ecosystem requires two attributes to function well. 

Advertisement

First, the IT infrastructure must be very cost-effective to make the investments in hardware and software worth their cost. Second, the database system must be fully secure and safe so that classified and sensitive data is not compromised. In both these cases, database migration from Oracle to SQL Server is an assurance in this regard, along with high data durability and integrity. 

Let us now explore how these two factors – cost effectiveness and data durability and safety – are optimized by migrating databases from Oracle to SQL Server.

Benefits of migrating databases from Oracle to SQL Server

Advertisement

Benefits from technologically advanced features.  

# The SQL Server is user-friendly and easy to install without any command-line configuration. The installation is seamlessly completed by a Setup Wizard, and once the process is completed, all upgrades are automatically downloaded. Comparatively, it is not so simple with Oracle, where additional drivers and applications must be downloaded first before initiating the setup.  

# In SQL Server, it is possible to recover lost data in the event of a database crash or outage.  This is because of the attribute of the database engine that helps to store data with queries being run via files, indexes, and transactions. Hence, when there is an issue with the database functions, it is not difficult to restore and recover lost data. This is a critical reason for organizations preferring to migrate databases from Oracle to SQL Server. 

Advertisement

The data recovery cycle is as follows.

Before a transaction is completed in the SQL server, log records are noted on a disk. When an outage or unexpected break in operation occurs, the transactions help to maintain functional continuity and, hence, there is no break in work or downtime. When the issue is subsequently resolved, the logs restore the database from where the break occurred. This prevents any degradation or data loss from any unfortunate reason. 

# Data security is another area where SQL Server steals a march over the Oracle DBMS. Here, access to the database is strictly controlled through highly effective access management programs, and classified and sensitive data is firewalled optimally. Additionally, SQL Server data is completely encrypted and protected through smart and intelligent algorithms.   

Advertisement

While these technologically advanced features are enough to make organizations migrate databases from Oracle to SQL Server, let us check how SQL Server is also ahead as a cost-effective platform. 

Benefits from cost-effective features

# A cutting-edge feature of SQL Server is data compression to the extent of 10x. Since businesses store huge amounts of data, compression frees up space for more data to be accommodated in a fixed storage volume, approximately one-tenth of what would normally be required. This, along with data consolidation and visualization of servers, leads to substantial savings for businesses.  

Advertisement

# The SQL Server offers several versions of its database management system, thereby allowing users to opt for one that meets their requirements. They do not have to pay high license fees for top-end products that they will not use. 

Let us go by an example for a clearer understanding of this point.

The SQL Server offers several versions at various price points in license fees. At the bottom is the free Express editions with very limited storage and features, but ideal for individuals and startups. Above that is the Standard edition with a low price but more features than the Express edition, just right for small and mid-sized businesses. At the top of the pile is the Enterprise edition with high license fees and cutting-edge features, making it ideal for large companies and corporations. 

Advertisement

Businesses can start from the Express edition and work their way up to expansion without having to spend more for features that they will not use soon. In comparison, Oracle charges a flat licensing fee for storage and other features that must be paid for even if not required. 

Because of this cost-effectiveness, it makes sense to migrate databases from Oracle to SQL Server.   

Migrating Databases from Oracle to SQL Server 

Advertisement

The SQL Server Migration Assistant (SSMA) for Oracle is used to ensure a seamless migration process. The Assistant reviews data and database objects, and accesses databases for migration. However, a more complex groundwork must be prepared by DBAs when SYS and SYSTEM Oracle schemas are involved, as they cannot be migrated straightaway.   

There are two processes that may be followed to migrate databases from Oracle to SQL Server. 

# One-shot method: Here, all systems are shut down and the whole database is migrated in one go. The reason for the downtime is to ensure that all existing data is moved and that no data generated after migration is present in the source database and not moved to the target database. 

Advertisement

# Phased method: Here, Oracle to SQL server migration is done in two stages. First, the data is migrated without shutting down the systems. Next, all incremental data generated after the last migration run is moved from the source to the target database at pre-defined intervals.  

Organizations can choose any one that matches their needs, though large corporations would not want to shut down databases as in the first method.
