What is the Transmission Control Protocol (TCP)?

Networks are essentially communication – a non-stop interaction between machines exchanging information. To guarantee the success, efficiency, and security of that communication is a complex task. It can’t really be compiled through the use of a single technology. Instead, a combination of protocols and tools is what makes it possible.

What is the Transmission Control Protocol (TCP)?

The Transmission Control Protocol (TCP) is a communication protocol used to protect data exchanged between a client and a server. It has a specific way for organizing the data to keep their integrity, from the moment they are sent and until they are delivered. It’s a popular protocol used on many networks and supported by applications and devices.

It’s worth mentioning that the TCP is used by most networks, combined with the Internet Protocol (IP). They are different protocols, but since their combination became the official standard for applications and devices to communicate over networks (TCP/IP) a long time ago, in the late 1970s, some don’t differentiate them anymore.

Just keep in mind these teammates complement each other, but each has its own functionality. The IP routes and addresses data packets (sender-recipient). TCP organizes and protects them.

How does the Transmission Control Protocol (TCP) work?

First, TCP is a connection-oriented protocol. That means that to secure the data during their trip through the network (or networks), TCP requires an active connection between the sender and the recipient. And this connection has to keep active from the moment data are sent until they are delivered to complete the process successfully.

Then, when communication starts, the first action executed by TCP is to cut the message into packets. As a security measure to protect the integrity of the message, all packets get numbered by TCP and transferred to the IP layer after that for transporting them. 

It’s important to say that even all packets belonging to the same message, once cut in pieces, will not necessarily all travel together or follow the same route. They can move through different routers and gateways, and still, they all have to arrive at the same destination. 

Once they all hit this point (destination), TCP must reassemble all data packets to shape the original message that must be delivered to its recipient. Here, a process without problems should finish. But there can be issues, and TCP functionality is designed to react in case they arise. 

For instance, data packets can get disordered, duplicated, or lost during the process. TCP can detect and fix those types of problems. TCP will ask the packets that are missing to be sent again to re-organize them, re-order and deliver the message correctly. If the message definitely can’t be delivered, TCP will report the situation to the sender.

If you imagine the number of messages that are sent every minute, then cut in pieces by TCP, you can get an interesting image of how active and massive the transit of data packets is on every network. 

Advantages of the TCP.

  • It’s an open protocol. 
  • It’s a light protocol. Its presence doesn’t stress networks or devices.
  • It’s not dependent on the operating system.
  • It supports different protocols for routing, communication within a network, and different networks.

Disadvantages of the TCP.

  • It’s not a choice for LAN or PAN.
  • It has vulnerabilities. Cybercrime could take advantage. 

Conclusion.

TCP can totally contribute to the safe exchange of data on your network. The right combination with other technologies can enhance it. 

A breakdown of the Web hosting types

What is Web hosting?

Web hosting is a service that lets businesses and individuals publish a website or web page successfully on the Internet. Web hosting service providers supply the technologies and assistance required for the website to be noticed on the Internet. Websites are stored or hosted on servers. When users want to connect to your website, they have to type your domain name into their browser. Next, their device will connect to your server, and your website will be displayed to them by the browser.

Shared Web Hosting

Shared hosting is when several websites are hosted on the same server.

Keep in mind that if you decide to use this type of hosting, you will share the resources of the server with other domains, for instance, CPU and RAM. Therefore, shared hosting is the best option for new websites and beginners because it is the most affordable of all. Yet, it is essential to mention that some performance difficulties could appear, and sometimes you could experience slow loading times. Unfortunately, there is a chance one of the other websites on the server to experience a traffic spike. Such type of situation could reflect on your webpage too and affect the performance. 

Dedicated Web Hosting

If you decide to use Dedicated Web Hosting, you are going to receive a server that is dedicated to operating only for you. Therefore, it gives you an excellent opportunity. Furthermore, as a result of that decision, you will benefit from the fast speed and more uptime. Still, receiving more advantages also means it will require from you a larger budget for hosting only your website on that particular server.

You additionally have the ability to get overall technical control over the server settings. So everything you could be concerned about your website, software, configurations are all things you could define yourself.

VPS Hosting

VPS is the short acronym for Virtual Private Server. For many, it could look like this type of web hosting is much more superior to shared web hosting. Actually, that assumption is correct. Users that outgrow their shared plans usually consider upgrading exactly to a VPS hosting. With this kind of service, you still share space on a singular server with others. However, the key difference is that their number is way lower.

VPS hosting is considered one step after shared hosting and one step before committing to a dedicated server. Additionally, it is preferred by some users because they want more control, but dedicated hosting is not their answer when it comes to discussing the budget. Advanced website owners that desire specific software and package installations also get satisfied with VPS hosting.

If there are significant amounts of traffic, it is essential to know that VPS hosting is also not very efficient. That is why the performance of your website can still be affected.

Cloud Hosting

Cloud Hosting allows an on-demand hosting solution. It works with a network of interconnected servers thanks to a virtualization process. 

If one server is compromised or not working, the rest of the servers will continue to function. So, as a result, it won’t affect the performance of your website. In addition, the users are able to benefit from the scalability and better uptime thanks to the fact that their website is stored on several servers at the same time.

It is no surprise that many users see cloud web hosting as pretty attractive rather than traditional web hosting.

​How to start a website: 5-step guide

This article is for all of you that have a business running or have an idea and plan for their business. It will focus on the main decisions and steps of the process of how to start a new website. 

​1. Define your website budget

Creating a website is a process like any other project in your organization. The first step of starting a website is planning. Think about the purpose of your site and all the features it needs. Define how much money you are willing to spend on it. There are plenty of options, and many could be overkill for your needs. Think well and define your budget that involves money for software (CMS, themes, plugins, etc.) for freelancers or agency (design, programming, content, etc.), services (hosting, DNS, domain name, etc.), marketing (advertising, off-site SEO, promotions, etc.). 

​2. Choose your platform

Currently, if you want to start a website, your best choice is to use a Content Management System (CMS). It is software that includes almost everything that you need to start a website. It will be the framework for it, and you can expand its features with plugins and addons. The most popular one is WordPress, but there are many more like Joomla, Magento, WooCommerce, Wix, Shopify, and more. The decision will be taken based on your needs (what kind of site it will be), budget (some are free, others cost), and how popular it is in your country (you need specialists to work on it and with it). Migrating from one platform to another is possible but not easy so better choose wisely. 

​3. Get services

Another step in starting a website is paying services like:

​Domain name. 

It is a must-have. It is the name of your business online. You should search for a domain name that is easy to remember and, if possible, to match your existing brand. Another thing to consider is the price per year and price for renewal of the domain that might differ for the various top-level domains (TLDs). 

​Hosting. 

The hosting should preferably be located near your target audience. Think about from where the people will visit you and choose there. Based on your budget, needs, and the type of site you need, you can choose a basic shared hosting, a more advanced virtual private server (VPS), or even a dedicated server. Choosing a company that has more plans and options could help you in the future. 

​Additional services.

You could get additional services like DNS plan, DDoS protection, Content Delivery Network (CDN), Backup services, and more. Most of them add value to your company, but please be careful because the bill can get larger quickly. 

​4. Create the content

Having an empty canvas does not mean having a website. Now you need to fill it with original content, attractive images, and videos. If your company has the resource, you could do it alone, but you can also choose to hire a marketing agency or freelancers for the task. What you need is original content that you have the right to use, and it is well-written. Having excellent content written according to the latest SEO trends will help you rank better on the search engines.

​5. Advertise it.

Now that you have everything up and running, your last step in starting a website is to show it to the world. Think about an SEO strategy that will put your site on the “organic” results of the search engines and an SEM strategy for the paid section. You need to think about each section of the marketing funnel and create specific actions for them. Bring not only more people but the right people too!
