            When first delving into Java, a programmer must download the Java development kit (JDK) from the Oracle website and choose the integrated development environment (IDE) where they will build their code. Downloads must be done through a trusted source to keep the system secure. The version needed will depend upon the user's operating system. The install programs will give step-by-step instructions for easy installation, and additional support is provided in the instructions on the website. When installing these items, the JDK should be downloaded first. There are several options for IDEs, such as Eclipse and NetBeans , so users should consider their preferences when choosing their IDE. Next, it is essential to understand what kind of programming language Java is and the basic concepts. Below is a summary of the fundamental concepts of Java, with links provided for further understanding. Java is an object-oriented programming language (OOP). An OOP may be a powerful

  Information Technology Careers              Information technology is an exciting and constantly changing field of study. A degree in technology provides individuals with the opportunity for a career in top-ranked jobs (Vahid & Lysecky, 2019). How does an individual know what career is right for them? Information technology is a relatively new career path. However, it is one of the fastest growing. With technological advances being made every day, new job roles are forming to fill the changing needs of businesses. Career competencies are positively correlated to career adaptability and success in an individual’s career (AlKhemeiri et al., 2021). Technology’s constant evolution requires individuals to have a broad knowledge of the fundamentals of technology concepts to maintain adaptability. To succeed in a career in technology, individuals should understand the history of computers, have knowledge of hardware and applications, and comprehend network architecture to succeed.  

Network Security Network security is a necessity to provide computer security and avoid security breaches. Network security requires more than antivirus software and firewalls. Users must know how to protect their privacy. They should manage the information shared on the internet, adjust privacy settings on apps, and be aware of social engineering ploys to obtain personal information Vahid & Lysecky, 2019). Valuable information should be sent through secure channels using hypertext transfer protocol secure addresses and be encrypted. It is important to remember that users are not anonymous, and data can be easily intercepted. Users should understand network security to protect against spam emails with malware and phishing and even aid in defending denial-of-service attacks. Spam emails are unrequested mass-produced emails. Although most spam is used for marketing, some contain files with malware or use phishing to scam users. (Vahid & Lysecky, 2019). Users receive emails that

Computers in Food Service Technology has infiltrated almost every industry. Computers are found everywhere. One of the prevalent applications of this is observed in the restaurant industry, particularly fast food. Technology has revolutionized fast food service—the computer’s steam line service, starting with ordering. Innovative restaurants have pioneered point-of-order touchscreens (Figure 1) for in-store orders and mobile apps (Figure 2) for customers to order before entering the doors. Once the customers enter their orders into the computer, they are sent to the kitchen and displayed on monitors at every station. This allows the orders to be split into parts, only sending relevant details of the order to the station necessary to assemble this item. Figure 1: Kress, M. (2022, Dec. 1).

  Ping and Traceroute Commands Computers use packets to communicate through the internet. A packet contains the sender’s and destination’s address and other data a user may want to share (like an email, link, picture, etc.). A packet is sent from one computer to another computer through the use of an IP address. When the packet leaves the sender’s computer, it passes through several routers until it reaches the final destination. These packets can be traced to assist users in troubleshooting network issues. A ping request lets users see if a device or website is accessible and how promptly it may be retrieved. Pinging an address is an excellent resource for troubleshooting. A ping can allow the user to see if there are network issues by confirming if there is connectivity between IP addresses. When pinging an address, the user can view how long a reply takes, how many packets were sent and received, and if any packets were lost. When problems occur with accessing websites on a brow

  Microsoft Office Applications Microsoft Office 365 is an essential tool for any business. Office 365 provides applications in word processors, spreadsheets, databases, and presentations. Additionally, Microsoft allows businesses to easily share data within the company through a cloud application (Skendzic & Kovacic, 2012). Storing data in a cloud allows multiple users access to the information and editing capability for collaboration. Furthermore, a cloud permits users to access needed information from other devices. Microsoft is among the most widely used and inexpensive programs (Skendzic & Kovacic, 2012). Office allows businesses of all sizes to access necessary programs at an affordable price. Companies should invest in Microsoft Office 365 for its word processor, spreadsheets, database, and presentation applications. Word processors are a necessary item for a business to have. They allow the user to generate formatted text. (Vahid & Lysecky, 2019). The user may s
