The world of IT is ever-evolving therefore stepping into this realm as a beginner might feel like embarking on a journey through a dense, uncharted forest. In this world, mastering specific IT skills such as programming languages, cybersecurity, and data analysis is not just an asset but a necessity.
As someone who knew next to nothing about IT, I have gained so much proficiency in these few couple of months due to practical tips and a few resources that act as a guide for someone who is a new participant in the IT world. Therefore, I would love to share those insights with you. Whether you are an aspiring coder, a future cybersecurity expert, or data enthusiast, there’s no need to look further as you have come to the right place.
- PROGRAMMING LANGUAGES
What is a programming language you ask? Well, a programming language is a formal language that specifies a set of instructions for a computer to perform specific tasks, solve problems, or create software applications1. (the instructions can also be referred to as an algorithm).
Programming languages are used by software developers to write, design, and implement computer programs. They allow us to translate our thoughts into instructions computers can understand.
Each programming language has its own syntax and rules, which dictate how a code should be written and organized.
Python, for example, is known for its simplicity and readability, making it a popular choice for beginners. It is widely used in fields like web development, data analysis, and artificial intelligence.
Java, on the other hand, is a versatile language that can run on any platform. It is commonly used in building enterprise-level applications, Android development, and large-scale systems.
C++ is a powerful language often utilized for system software, game development, and resource-intensive applications. Its performance and ability to directly manipulate hardware make it a preferred choice for performance-critical programs.
JavaScript, primarily used for web development, enables dynamic and interactive elements on websites. It is a client-side language that runs in web browsers and allows developers to create dynamically rendered content and interact with users.
Other programming languages, such as Ruby, Go, and Swift, cater to specific needs and preferences. Ruby is often employed for web development and scripting, while Go is preferred for building scalable and efficient network services. Swift, developed by Apple, is commonly used for iOS and macOS app development.
- CHOOSE A LANGUAGE
Choosing a language depends on various factors. These may include project requirements, how easy it is to use, performance, community support, and the availability of libraries and frameworks. As a beginner the process of choosing a language can be very overwhelming because there are many options to pick from and a lot to consider. However, with proper research, you will be able to determine which language aligns with your goals and interests. It is also wise to use multiple programming languages to take advantage of your strengths and address different aspects of software development.
- ONLINE COURSES
Platforms such as Codecademy, Coursera, FreeCodeCamp and many more can offer excellent courses for learning programming. Also, YouTube is a great resource for learning too.
- COLLABORATION
Joining coding communities and forums where you can connect and share knowledge with other developers such as Stack Overflow, GitHub, or Reddit’s programming subreddits. This can accelerate your learning.
2. CYBERSECURITY
Cybersecurity refers to the practice of protecting computer systems, networks, programs, and data from digital attacks, unauthorized access, damage, or theft. Its primary goal is to ensure the confidentiality, integrity, and availability of information in the digital realm2.
- SECURITY BASICS
As a beginner in the cybersecurity field, it is important to start by understanding the fundamentals. This includes concepts such as encryption, network security, and common threats.
Encryption is a key aspect of cybersecurity, involving converting information into an unreadable format to ensure confidentiality.
Network security focuses on protecting computer networks from unauthorized access, misuse, or disruption.
Being aware of common threats such as malware, social engineering techniques, and phishing attacks is crucial.
By understanding these fundamentals, you will gain the knowledge and skills needed to navigate the cybersecurity field and contribute to a more secure online environment.
- COURSES AND CERTIFICATIONS
Just like programming, you can also join online courses from platforms such Udemy or Cybrary, also consider pursuing CompTIA Security + or Certified Infromation Systems Security Professional (CISSP)certification.
3. DATA ANALYSIS
Data analysis is the process of inspecting, cleaning, transforming, and modelling data to discover useful information, draw conclusions, and support decision-making. It involves examining raw data to find patters, draw inferences, and extract meaningful insights. Data analysis is a crucial component in various fields and industries, including business, science, healthcare, and social sciences3.
- LEARN DATA TOOLS
It is important to familiarize yourself with data analysis tools like Pythons’ Pandas. Jupyter Notebooks, and libraries like NumPy and Matplotlib for data manipulation and visualization.
- REAL-WORLD PROJECTS
Apply your skills to real datasets. Kaggle provides datasets and competitions where you can practice data analysis and machine learning. It provides excellent opportunities for individuals to apply and enhance their data analysis and machine learning skills.
