We will be looking at the Transmission Control Protocol, (TCP), as well as Internet Protocol (IP) technologies in this article. We will also discuss the Application layer protocols, and the Stateless protocol. This information will help you understand how to use and implement network protocols. This information will allow you to learn more about each protocol's history and its functions.
Transmission Control Protocol
TCP/IP is a combination of the Internet Protocol (IP) and Transmission Control Protocol (TCP). The IP layer determines how packets are moved through a network. The TCP layer ensures reliable data transmission across Internet-connected networks. TCP inspects packets for potential errors and makes requests to retransmit if necessary. This allows any computer to communicate with any other.
TCP protocol can help reduce latency. A delay in acknowledging a receipt device from TCP can cause data loss. TCP organizes data packets into segments, or components. TCP protocol demands that each segment contain a checksum fields to ensure that no two packets can be identical. If the checksum field is corrupted, the destination will not send an ACK.
Internet Protocol
Transmission Control Protocol is one of many protocols that make up the Internet protocol suite. It was originally designed to be used in network deployment and it was later extended to include Internet Protocol (IP). The entire suite of protocols is commonly known as TCP/IP. TCP, a type data protocol, facilitates communication over long distances.
The difference between TCP and IP lies in the way they work. TCP and IP are both connectionless. They act as datagram services. TCP however, is more reliable. It establishes consistent and reliable communication sessions. IPv4 is still the most common version of the Internet Protocol. However, IPv6 will be more popular for private and public networks.
Application layer protocols
TCP/IP protocol stack includes several layers. Each layer has its own set of rules, responsibilities and regulations. Each layer exchanges data by agreeing how to pass information from one another. Because each layer is composed of several components, the protocols it uses to communicate data are very similar to stacking blocks. In fact, the protocols are often called stacks, which is why they are arranged in layers that are related to one another.
The application layer is the topmost layer of the TCP/IP model, and it specifies the protocols used by application processes. This layer provides global access to information and facilitates communication between applications. It also helps with communication synchronization and resource availability. As an example, the application layer enables users to access the World Wide Web by connecting to remote servers and receiving messages.
Protocol without state
A stateful protocol means that a server needs to have some information before it can send data. This is a requirement for computer applications. For example, a phone cannot browse the internet without a server. The server then processes the client's request. Different protocols have different levels of dependency between the client and server. Stateless protocols have less dependency because they don't have that dependency.
Because they don't require as much information to be orientated, stateless protocols use less resources than stateful protocols. There are some drawbacks to stateless protocol. Sometimes, a stateless protocol may not work best for a system. For example, it might not be able identify the source for spam messages.

How do I create a free website?
It all depends on which type of website it is. Are you looking to sell products, build a website, or create a portfolio online?
An essential website can be created using HTML and CSS. This is a combination of HyperText Markup Language (HTML) and CascadingStyle Sheets (CSS). You can create a simple website with HTML and CSS. But most web developers recommend using a WYSIWYG editor (such as Dreamweaver, Frontpage).
Hiring a freelance developer is a good option if you don’t have much experience with designing websites. They can help create a custom website for you based on your requirements.
A freelance developer may charge you either a flat-fee per project, or an hourly fee. The cost of hiring a freelancer varies depending on how much work they complete within a given timeframe.
For example, companies may charge 50-100 dollars an hour. Higher rates will be charged for larger projects.
Many freelance websites also list open jobs. You can also search on those websites before you reach out to developers.

Freelancers need to promote themselves. Advertise your services on job boards such as Indeed, Guru, Guru, and Upwork.
Freelancers receive assignments often from recruiters who post open positions online. These recruiters look for qualified candidates to fill specific positions.
These recruiters will typically give the candidate a project brief that outlines the position's requirements.
Freelancers are not required by law to sign any long-term agreements. If you want to move ahead, it's best to negotiate an initial payment.
Designers prefer working directly with clients over working through agencies. Although this may seem appealing, many people lack necessary skills.
Agency workers have a deep understanding of the industry in which they are working. They can also access specialized training and resources that will allow them to produce top-quality work.
These benefits are not the only ones. Agency workers typically receive a higher hourly wage.
However, the disadvantage of working with an agency is not having direct contact with your employer.
To succeed as a UI designer, you must be self-motivated, creative, organized, flexible, detail-oriented, analytical, and communicative.
It is also important to have great verbal and written communication skills.
UI designers are responsible for designing websites by creating user interfaces (UI) and visual elements.
They are responsible for ensuring the site meets its users' needs.
This involves understanding what information visitors need and how the site should function.
Wireframes are created by UI designers using a variety of tools. Before beginning to design, they use wireframing.
You can find wireframe templates online. This makes it easy to make your own wireframes.
Some designers concentrate on UI design only, while others mix UI design with graphics design.
Photoshop is used by graphic designers to edit images.
Adobe InDesign is used to create layouts and pages.
Photographers capture images using digital cameras or DSLRs.
Then, they upload the photos to a photo editor program, where they add captions and filters.
After the shoot, the photographer saves and archives the image in a format compatible with website.
It is important that you consider all aspects of web design when creating a website.
This includes research and planning, wireframing, prototyping testing, coding, content creation and publishing.
Research – Before starting any new project, it is important to conduct extensive research.
Planning - After you have completed your research, it's time to start creating a plan.
Wireframing – A wireframe is a preliminary sketch or drawing of a webpage or application.
Prototyping - Prototypes help ensure that the final product matches the initial vision.
Testing - The prototype should undergo multiple rounds of testing to ensure it works properly.
Coding: Coding is the process of writing code for computers.
Content Creation - Content creation covers everything from writing copy to managing social media accounts.
Publishing entails uploading files to a server and ensuring the site is accessible.
You will need to have a broad knowledge of different projects in order as a freelance UX/UI developer.
Some companies require only wire frames, others require complete prototypes.
You may be required to perform specific tasks depending on the project you accept.
If you are hired to create wireframes for a company, you may be expected to produce several wireframes each time.
If you're being hired to create a full prototype, you might be asked to create a fully functional site.
