Communication protocols provide an avenue through which information can be sent and received from one location to another. Different protocols serve different purposes. Some protocols are used to protect networks, while others serve a convenience purpose. SSH, which is used to secure computers connected to an insecure network, can also be used by network administrators to remote control a system. Another common protocol is SMS, which is used to send text messages via cellular networks. While SMS is useful for sending text-based messages, it doesn't support pictures and videos. To send these types of messages, you must use Multimedia Messaging Service (MMS), an extension of SMS.
Functions
Protocols allow data to be transferred between two devices. They offer a variety of techniques for managing data traffic including data flow control, address, and synchronization. Each of these processes ensures that data arrives at its intended destination in the proper order. Some protocols can also be used to provide a limit on data flow.
Protocols specify the data that will be sent and the commands to send and receive it. Similar to a language protocol also provides rules for the meaning of data. These rules are also called the syntax and semantics in communications. They can be defined in formal ways.
Layers
Layers in communication protocols refer to the different parts of a network. Each layer serves a different purpose and handles different types data. The network layer handles addresses while the physical layer handles physical media. Each layer has rules that govern how data can be transmitted over a network.
A protocol can generally be broken into multiple layers and then organized by functionalities. Each layer is specifically designed to solve one type of problem. These layers can be used to send messages by selecting one protocol from each layer, and then adding a protocol selector.
Security
One of the most critical branches of cybersecurity is network security. Communication protocols play an important role in protecting network resource. The rise in cybercrime is due to the proliferation and security of computer networks. Protocols are used to protect networks. Protocols control how data is moved within and between networks, protecting it.
Modern internet security protocols protect against malicious activity and keep communications private. They include firewalls, antivirus software, and programs that neutralize spyware and adware. Some programs also filter out unwanted content from web pages and help to identify them. All these security features are part of secure communication.
Interoperability
It is common to use communication protocols to link two computers. In order to test their interoperability, the protocols must be tested by observing the behavior of IUTs. There are many ways to test interoperability between communication protocols. One approach is to use the test derivation method. This technique allows test case generation to be done automatically.
Conformance testing is a process that ensures interoperability between computer systems. Conformance testing examines how two communication systems are implemented against the standardized protocol specifications. Although this method can be used to ensure interoperability it has some limitations. Even though two conformant implementations might not communicate, it is possible for them to fail. These problems can be caused by ambiguity or incompatible option settings, incomplete conformance testing, and protocol standards that are unclear.
FAQ

Now that you know how to create the structure of a website, you'll also need to learn some HTML and CSS coding.
HTML stands for HyperText Markup Language. This is like writing a recipe. It would include ingredients, instructions, as well as directions. HTML allows you to indicate to a computer which portions of text are bold, italicized and underlined. It also lets you know which part of the document is linked. It is the language of documents.
CSS stands for Cascading Style Sheets. This is a stylesheet for recipes. Instead of listing every ingredient and instructions, you create general rules about font sizes, colors, spacing and other details.
HTML tells the browser how to format a web page; CSS tells it how to do it.
Don't be afraid to ask questions if you don’t understand any of these terms. Follow the tutorials and you will soon be creating beautiful websites.

Some designers focus solely on UI design, while others combine UI design with graphic design.
Photoshop is used to edit images by graphic designers.
Adobe InDesign is then used to layout pages and layouts.
Photographers capture images using digital cameras or DSLRs.
The photos are then uploaded into a photo editing program. Here they can add captions, filters, or other effects.
Afterward, the photographer saves the image in a file format compatible with the website.
When building a website, it is essential to consider all aspects of the design process.
This includes research, planning and prototyping.
Research – It is essential to do extensive research before you begin a new project.
Planning – After you've done your research you'll be ready to develop a plan.
Wireframing: A wireframe is a sketch of a website or application.
Prototyping-Prototypes ensure that the final product matches your initial vision.
Testing - The prototype should undergo multiple rounds of testing to ensure it works properly.
Coding – Coding is the art of writing computer codes.
Content Creation – Content creation includes everything, from the writing of copy to managing social networks 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.
