Network Security

Information and system security are important to individuals because so much personal and financial information resides on information systems that are inherently vulnerable to compromise. Information and system security are important to organizations for the same reason, but also important because the success of developed countries depends on the secure operation of systems that support utilities, finances, and government (Zwass, 2016, Information Systems Security). Countries depend on organizations, and organizations depend on individuals. All depend on information systems to manage and control activities in the modern economy.

Computers in the Workplace

I work for a natural gas company. When I came to work here, I was surprised to learn that local natural gas providers are transportation companies. We build and maintain infrastructure for transporting gas from our national provider to each of our customers. We bill for the amount of gas used, yet do not sell the gas itself. Technically, we charge for the transportation of natural gas. Computers are integral to the way we do business.

Traveling Through a Network

A packet travels through a data network much like a physical package travels to a destination. A router uses the address of a packet to determine the best route to the next stop (another router). A shipping company uses the address of a physical package’s address to determine the best mode of transport, e.g., truck, ship, or plane. In both cases, there is always more than one path to a destination.

The Role of Applications


My experiences creating a journal entry using a word processor, calculating percentages in a spreadsheet, developing a presentation, and manipulating a database were more challenging than I expected. I am familiar with all four of these applications, and most of my time was spent decoding the instructions to make sure I satisfied the assignment requirements. Each application is appropriate in different situations. Skills using each are valuable in both professional and personal pursuits.

Review of the iTunes Music App

The Music app on an Apple device is my answer to the problem of managing an extensive music collection. It is dependent on iTunes that can run on an Apple or a Windows-based computer. You can visit Apple’s website for learning to use iTunes, and I will not cover that here. The Music app can also stream radio stations and buy music from Apple. I have the buy music option turned off on my device.

I began ripping (converting wav files to mp3 files) music files from my compact disc collection in 1998. I have accumulated 67 Gigabytes (GB) of music files since then, almost 12,000 songs. It was only last year that I acquired a device with enough storage to fit all those files; an iPhone 8 with 256 GB of storage. I have tried many music managers over the years such as Winamp, MuzicMan, MusicMonkey, MusicBee, and others I no longer remember. They were all PC based, and it was always a challenge moving an extensive library of music from one PC to another. In that environment, iTunes was never my first choice, but it emerged the winner here because of the portability of the iPhone.

Programming Languages Reflection

Programming Languages Reflection


This post describes my experience learning to use an online service called Scratch (Scratch, n.d.) to create a program. Difficulties encountered and how I overcame them as well as insights gained are discussed. With many high-level programming languages to choose from, Scratch offers an economical way to learn concepts common to all of them.
