Activity 5 - Software, Hardware and Networks:

1. Which would you rather have—a handheld computer or a tablet computer? Why?

                I’d rather want to have a tablet computer.  Although handheld computers are smaller and occupy less space, I still want a tablet computer because it gives me a better view because it has a bigger screen compared to a handheld computer.  Applications are also easier to view and use because the tablet is bigger as well, the options are not that crowded and compressed.

2. If cost were not an issue, describe the characteristics of your ideal computer. What would you use it for? Which operating system would you want it to run?

                I want to use a computer for gaming purposes.  In the first place, I was into computers because of gaming.  The characteristics of my ideal computer would be mainly a core i7 processor, 1TB hard drive, 16-32GB RAM and 8GB Video Card.  That four is the basic characteristics of my ideal computer which allows me to play even the heaviest type of game available as of now.  Microsoft OS will be my preferred OS for my ideal computer, specifically Windows 7.

3. Define Software as a Service. Discuss some of the pros and cons of using software as a service.

                Software as a Service allows organizations to access business functionality at a cost typically less than paying for licensed applications since Software as a Service pricing is based on a monthly fee.  It is also hosted remotely so the hardware investment won’t be necessary.

PROS:

·                             It cost less

·                             It is easier to maintain

CONS:

·                            Communication(requires the internet)

·                            Data Security

 4. Why is an organization that employs centralized processing likely to have a different management decision-making philosophy than an organization that employs distributed processing?

                A centralized processing only has one management that is the one responsible for decision-making philosophy because it is centralized.  A distributed processing cannot have only one management to be responsible for the different branches available because it will take time and the efficiency of each processes must be efficient enough equally with each other.

 5. Social networks are being widely used today. Describe how this technology could be used in a business setting. Are there any drawbacks or limitations to using social networks in a business setting?

                The social networking sites now allows advertisements in some parts of their web page, example would be facebook.  It can be used in a business setting because it allows entrepreneurs to publish and advertise their products or services in the web through the social networking site that can be seen by almost everyone.  It can increase their market reach and might help their sales to increase.  The drawbacks of this type of business setting is that not all that inquires are buyers and also the sellers can also be scammers as well.  Security will be an issue and both the buyers and sellers must be careful in transacting through the web based business setting.

6. One of the key issues associated with the development of a Web site is getting people to visit it. If you were developing a Web site, how would you inform others about it and make it interesting enough that they would return and tell others about it?

                First is to develop a web site that is the current trend that fits the people.  As of now, social networking sites or social media is the current trend.  One must not only develop a social networking site with the same features of the other social networking sites available.  You can start by informing your friends about it and even publish or advertise it in other social networking sites for others to be curious and informed about it.  That is the time in which they can know what the site is all about and depending if they enjoyed or they snubbed your site will determine if they will tell others about it.
