Basics of IT

In the world of programming, Java stands out as one of the most popular languages. Whether you're a beginner or an experienced developer, understanding Java installation and object-oriented design principles is crucial. In this blog post, we'll provide guidance on installing Java and dive into the fundamental concepts of object-oriented programming (OOP) in Java. Java Installation: Installing Java on your system is the first step towards embarking on your Java programming journey. While we won't provide a step-by-step tutorial here, we recommend referring to the official Java website for detailed instructions tailored to your operating system. Once you map to the link below, you will be taken to a webpage that says Oracle, the current developer of Java. https://www.oracle.com/java/technologies/downloads/#java11 Once you have installed Java, you must download an Integrated Development Environment (IDE) software. The one we recommend is Netbeans. Like Java, you must c...

OS Theory Concept Map Section 1: -Categorize, describe, and give examples of the major functions of operating systems. One of the first and most significant functions of operating systems is to maintain supervision of the execution of user programs to prevent errors and improper use of the computer. The operating system acts as a crucial intermediary between the hardware and software, ensuring that user programs are executed in a controlled and secure manner. The kernel, as the core component, plays a central role in this function. It provides essential services and manages system resources, allocating them to processes and scheduling their execution. By overseeing memory management, the kernel ensures that programs do not interfere with each other's memory space, avoiding potential crashes or data corruption. Additionally, it manages input/output (I/O) operations, which are essential for interacting with devices like printers, scanners, and disk drives. Device management, as...

For the last several years, people have heard that the Technology industry is growing faster with each passing year, and it is becoming a very profitable career. When kids, teenagers, and even adults think about their future careers, there are always those thoughts of being an astronaut, a police officer, or a firefighter, but more and more thoughts and career goals incorporate Information Technology (IT). When people consider a job in IT, they often wonder how many careers there are to choose from within the IT industry. Many people know about computer programming, software development, or cyber security but may not realize that there are multiple avenues within each. Another interesting thing to know and learn is how much pay a person can receive in an IT career. Learning what the average salary is and what jobs pay the most and least. Along with salary comes the question of what level of education is needed to earn the average or highest-paying IT jobs. Many people have a knack for ...

Previously the commands of ping and traceroute were learned. These commands assist in troubleshooting network connectivity and issues. These commands are usually used to check, diagnose, and understand network issues. However, they can also attack other computers by sending large data packets to crash a recipient's computer or try to take over a recipient's computer and spread a virus. All the attacker needs is an IP address (Okta, n.d.). Luckily there are ways to counteract these attacks by always keeping software up to date, blocking fragmented pings, and enhancing the computers' ability to take on large packets with an overflow buffer. Ping commands are not the only way for attackers to penetrate or corrupt a system. Email spam and phishing are other routes cyber terrorists can take.   Email spam is an unwanted message sent to emails that advertise unwanted deals or products or irrelevant information. These emails can come from companies that a person already does busi...

Information Technology is used in just about every industry. One industry many people may not correlate IT with is the construction industry. I have eight to nine years of experience in the construction industry. When thinking about Information Technology, I couldn’t think of when or how we used it other than using our mobile devices to call each other. When I did construction, I mainly did the framing, which is the process of building walls, floors, and roofs. IT was building the wood frame of the house hence the name framing. As a grunt worker, I mainly used nail guns, measuring tape, or hammers to get work done. But there were times when we would need to do some math to make sure things were square, so we would use a calculator or a phone to do the Pythagorean theorem. Besides using our phones and calculators, our boss or superintendent would look at the plans and use a computer to order supplies. Regarding the plans or blueprints, Architects use CAD (Computer-aided Design) to dra...

An interesting experiment is using ping and traceroute commands on your computer. To use ping or traceroute commands on a windows computer right click the Start menu and click run. Then type cmd into the textbox and click OK. Then in the command prompt, type ping, then space, then the specific domain name or IP address, and press enter. Follow the same steps to perform a traceroute, but instead of typing ping, type traceroute. Using ping and traceroute, you send signals or packets of information from your computer to websites, other computers, or devices within the network. After sending the signal through a ping or traceroute, you will be able to see if the other device or website got the signal, if it was returned, and how long it took to reach the other device or website. If, when doing a ping for a device such as a printer in the local network and you receive a “request timed out” message, this could mean an issue with the printer, such as not being connected to the internet. I...
