Bulletin on Computer Ethics and Security

So, here is another entry on the bulletin of computer ethics and security. In this era, there is so many cases regarding cyber security. Hence, I feel there is a must to do a bulletin regarding this issue in order to keep everyone updated. In this bulletin, there are so many useful information related to cyber security. Enjoy reading!

Internet Technology (Building a Model)

Hello and a very good day to all readers! My friends and I have been working on our model for about a month now. We are so happy that we have finally completed the model. As for the network architecture, we use client server network. We classify our model as local area network (LAN). Next, for the topology, we go for star network topology. Below are the definition what we apply on our model.

Client/Server Network
- One or more computers act as a server that provide services, to the other computer on the network (clients) which request services from the server.

Local Area Network (LAN) 
- Is a network that connects computers and devices in a limited geographical area such as a home, school computer laboratory and office building.

Star Network Topology
- Consists of a central device (hub/switch) where all the nodes are connected to it using cables. Data travels from one node to another passes through the hub or switch until it reaches the destination node. Hub: Data travels to all the nodes and only the recipient node accepts the data. Switch: Data travels straight to the recipient.


Based on figure 2, we make the personal computer as our server while others as clients. The model consists of switch. Our reason of choosing star network topology is because it has many advantages. The advantages are, if one node fails, it does not affect the rest of the star topology and adding or removing nodes will cause little or no disturbance to the rest of the network. As mentioned earlier, we classify our network as LAN. LAN allow users on the network to share resources, such as printers, large hard drives,data, programs, in a limited geographical area. Plus, LAN reduces cost because the resources can be shared. We imagine our model is in an office.

The client server architecture allows a server to store an organization's email messages. Client server network works with any size of networks and does not tend to slow down with heavy use. In addition, the security is more advanced than peer-to-peer network, you can have passwords to own individual profiles so that nobody can access anything when they want.

My experience learning Computer Science

I have been neglecting the importance of learning computer science before I entered college because I was very sure that I would not be associated with it in the future. In fact, I was very wrong. We should really learn about the computer in terms of how to use Microsoft Words, uploading files, managing files and so on. After entering college, I was exposed to computer science. Starting from the very first class, I realized that to learn computer science is very important. It really helps when I am to prepare my slides for presentation, doing paperwork and the list goes on.

  Most of my friends know how to use the computer very well. I felt ashamed for not being able to use the simple functions. Starting from that point on wards, I slowly learn the basics of computer science. I managed to improve myself day by day. The satisfaction of knowing how to use the computer is great. Now, I feel more confident whenever I am instructed by my lecturers to do any assignment which needs me to use the computer.

Reasons You Should Learn Computer Science

As the world today is developing rapidly, humans are becoming more modern with the creation of information technology. It is now easier to communicate with the people around us through Whatsapp, Facebook, Twitter and so on. Imagine if there is no information technology, what will happen? It is amazing how the ancient people were able to communicate with each other without information technology. Here I would like to list down the importance of mastering information technology.

Choose from Different Career Paths

Information Technology (IT) allows you to take your career in a number of different directions. Become a computer network architect, a computer programmer, a computer systems analyst, a database administrator, an information security analyst, an information architect, a web developer and so much more! South University even offers specializations in Database Development and Administration, Information Systems Security, Network Administration and Management, and Multimedia and Web Development.

Find Work Almost Anywhere

Nearly every company needs a team of savvy computer experts to keep its systems up and running. You can find work in just about every industry you’d like, such as financial services, entertainment, government, hospitality, healthcare, manufacturing, retail and more.

Thrive as Part of a Team and an Individual Contributor

If you think IT work is completed mostly on a solo basis, you may be surprised to learn it’s actually largely a collaborative effort. You’ll likely be working closely with your colleagues on a number of group projects, allowing you to be part of many larger scale initiatives. Don’t worry if you also like some time to work on solo projects, as you’ll also have plenty of opportunities to complete assignments on your own.

Enjoy the Opportunity to Keep Learning

Companies are aware that technology changes at the speed of light, which is why many organizations invest heavily in the continuing education of information technology workers. Enjoy working in a field where you’re encouraged to never stop learning.

Explore Your Creative Side

Much of the IT process actually relies on creativity and problem-solving. This field provides you with the unique opportunity to use your tech skills to come up with innovative solutions to problems faced by your clients, company and the population as a whole. You have the opportunity to use your skills to make major contributions.

Turn Your Talent into a Career

As a naturally tech savvy person, you’ve probably been interested in computers since you were pretty young. You’re in a unique — and wonderful — position to turn something that’s always been a hobby into a rewarding career. What could be better than finding a career that you truly enjoy?
