...communications, telephone traffic is a big benefit of that. The WLAN is also a great benefit because it supports both data and voice traffic, making it less money because the two are combined. They offer all types of new applications and different types as well. Wireless PDA’s are a type of advantage to the WLAN as well. They make accessing voice and data much easier to access and more viable to use (Geier, 2003). When looking into disadvantages there are a few of those as well. They were not designed for streaming media, and will cause congestion in the network. Another big problem would be voice mobility. Since most phone users are much better at being more mobile than data users, it causes a problem as well. Most people have an easier chance when they are moving around talking, then they are at texting. It is so much easier sometimes to talk, than it is to type. A person can easily tell each other what is on there mind in a few minutes, when it might take a few more minutes to try and type it out. Time can easily be saved in just talking on the phone. Security over the WLAN would be a big disadvantage as well. So many people try and hack people over their wireless networks all the time. If you do nothing about making your computer secure, or your network secure, you probably might get your networked hacked. You have to always try and secure your networks (Ellis, 2003). When you look to try and fix these disadvantages, there are many different ways to handle...

...Advantages and Disadvantages of information technology in Business Advantages: * Increases production and saves time: Business use technology to automate tasks. A good example is a bakery which uses automated temperature censors to detect any drop or increase in room temperature in a bakery. These censors will send information directly to the operator and report any temperature change. This saves the bakery time and it also results into quality products. * Improves communication through communication technology: With the help of communication technology tools like phones, video conferencing , electronic mail, databases just to mention but a few. Movement of information with in an organization or business has become easy and first. Employees can easily move information across departments without having any interruptions. Tools like electronic mail , e-fax, mobile phones and text messaging enhance the movement of information among employees , customers and business partners or suppliers. * Improves data storage and file management: Businesses use cloud hosting services to store and backup business data. Also it saves on paper work and makes transfer and access of data remote. With services like ‘’Dropbox.com’’, business owners can access their data any time any where. Information and data are very important tools for a business, so it is very essential to store them safely and also access them at any time of need.

...levels of security for various needs. These differing types of clouds and networks as a service offer off site data storage in a secured location, which in essence frees up space and virtual infrastructure for personal and/or business networks, and devices. There are advantages and disadvantages to cloud computing, just like any other product or service. The advantages being, storage for data, accessibility from virtually anywhere there is a network connection, automated management, security, apps, tools, etc. The disadvantages include monthly costs for space on the offsite network, security, involvement of a third party, no access to the physical structure - which means if the cloud server goes down, your data may not be accessible, etc. There is one instance with cloud computing that is both an advantage and a disadvantage, and that is the security. While a cloud may be more secure than your own network How?, personal or business, using cloud services puts the security out of your hands in both the physical and logical sense. Using a cloud, means the security of the server, both physical and virtual is in the hands of a third party. While in some cases it means upgraded security, this may not always be the case. The biggest disadvantage to third party security is the lack of control. You are relying on someone else to ensure that they can not only protect the data physically, but as well as from outside threats. This paper will delve...

...New Frontier: Data Analytics Phylicia Marie Phillips Professor Progress Mtshali, Ph. D. Information Systems Decision-Making April 17, 2016 In the past, analytics was reserved for back-room debates by data geeks producing monthly reports on how things are going. Today, analytics make a difference in how a company does business, day to day, and even minute by minute; more specifically how Walmart does business. As many know, Walmart is an American based multinational retail corporation that operates a chain of hypermarkets, grocery stores and discount stores. With over eleven thousand stores and clubs in 27 countries, information technology and data analytics play a major role in Walmart’s survival and helps maintain its competitive advantage. Data Analytics Overview The business intelligence and analytic technologies and applications currently adopted in industry can be considered as BI&A 1.0, where data are mostly structured, collected by companies through various legacy systems, and often stored in commercial relational database management systems (Bottles and Begoli, 2014). The analytical techniques most commonly used in these systems, popularized in the 1990s, are mainly grounded in statistical methods developed in the 1970s and data mining techniques developed in the 1980s (Chiang, 2012). The digitalization of information has created more data and the development of cloud computing, and faster and faster computers has made the increased data more accessible...

The disadvantage for RAM is that is is a volatile memory. When the power button if off the data/information is gone. This basically means that there could always be a slight chance that you data could not be there next time. There is also a lot of time wasted loading an operating system.An alternative is nonvolatile RAM, but it is slow in comparison to standard RAM. The disadvantages of a hard drive are simple because the main problems I see are that the hard drive is a big...

...applications. Instead of getting a standardized database program out of the box, you get a program that can be customized to fit your needs. This makes it possible to create a database that only has the features you need. Another advantage is Data Mining. It makes it possible to find relationships in data that would otherwise be difficult to find on your own. As good as the above sounds it also comes with a couple of BIG disadvantages. The biggest would be the cost, if you plan on using the program on multiple computers, you will need to buy licenses for each computer. If you plan on making the software available on many computers, these costs can really add up. Another big disadvantage is it comes with a learning curve; this is not something that you can pick up in a short period of time. Microsoft SQL Server MS SQL Server is a Client-server relational database system, with no UI development tools built in. Some of it advantages are, Maintenance its has lots of tools for maintenance, can do most of it with users in DB. It is user friendly, great security, it minimizes redundancy, and it is very consistent. It also works great on an enterprise scale it is designed to support a lot more users and scales better to handle them. The only disadvantage I could find is the cost, and that some of the features can bill considered over kill and since there is so many it too can come with a learning curve.

Also it would be easier for the MRs to add up a total instead of using a pen a paper it would a lot of time and a risk of mistakes happening. 3. Advantages and disadvantages of using an Electronic Spreadsheet. Best type of devices suitable for this task. The advantages for this is when all the data is taken, it is much easier and faster to calculate the total and generating graphs. The disadvantages for using this is if the company hires someone with no experience of using an Electronic Spreadsheets, they may take some time to learn how to use it and also there is a high chance in causing a big problem on the spreadsheets, having all the data incorrect. The best devices for this task would be an iPad or a tablet because it would much easier for the MRs to...
