Alisha J. Valdry
I am currently a student at Louisiana State University, on the way to earning a Bachelor’s of Science in Information System and Decision Sciences Degree. During my undergraduate curriculum, I have been able to work as a computer technician at the Department of Residential Life. I get great joy from providing technical support to ANYONE that needs it. As a student at LSU, I've been able to flourish my skills as a "techie." The IS and IT courses are so exciting, that I can't help but soak in everything I've learned. I was fortunate enough to complete an internship with Walt Disney World's College Program. Along with the unmentionable perks, I visited the grounds of Disney I.T. I spoke with ABC network technicians, ESPN tech support, and many others. After leaving the offices, I knew technical support and customer service was the job for me! In addition to recent management projects, other presentations, and a “happy thoughts” personality, I've developed an affable trait that displays in my work. The ability to communicate and having a personal sensitivity to people and their situations drives me to educate people where they may feel most uncomfortable, technology. This sensitivity to others is essential in any job. It generates a positive attitude that seems to spread and encourages others to do their best in the workplace. With my training in information systems and technology, the ability to manage multiple projects simultaneously, professionalism and strong work ethic, I am certainly a perfect fit for your company.

Application Layer
The Application Layer is the top, or seventh layer of the Open Systems Interconnection Model. Contrary to what most believe, this layer does not include software applications such as Microsoft Word, or Firefox. Instead the Application Layer services communication between software applications and lower-layer network services. This way, the network can interpret an application's request. The application can then interpret the data from the network.

The application layer is more like a service layer that does routine maintenance checkups to make sure data can be sent and received as it should be. The Application Layer focuses more on network services, APIs, utilities, and operating system environments. This layer provides the following services:
 * Makes sure that the other party is identified and can be reached
 * If appropriate, authenticates either the message sender or receiver or both
 * Makes sure that necessary communication resources exist (for example, is there a modem in the sender's computer?)
 * Ensures agreement at both ends about error recovery procedures, data integrity, and privacy
 * Determines protocol and data syntax rules at the application level

Network Services
The network services handle most notably file and printing, name resolution, and redirector services.

Name resolution is the method of mapping an IP address to a user-readable name. For instance, everyone knows the megasearch engine, Google.com, however, not many know the ip address of Google. Without name resolutions, we would have to remember four octets of numbers for each website we wanted to visit. Do you know the ip address for Facebook?

A redirector, otherwise known as a requester, is a service that is largely taken for granted. It is a handy little service that looks at requests a user may make: if it can be fulfilled locally, it is done so. If the request requires a redirection to another computer, then the request is forwarded onto another machine. This enables users to access network resources just like they were an integral part of the local system. A user could browse files on another computer just like they were located on the local computer- obviously redirector services are fairly powerful.

Application Layer APIs
API simply stands for Application Programming Interface. An API is just a collection of functions that allows programs to access an internal environment.

Network Utilities
The major application layer utilities are:


 * 1. Address Resolution Protocol (ARP)
 * 2. Netstat
 * 3. Ping
 * 4. Tracert
 * 5. FTP and TFTP
 * 6. Hostname
 * 7. Whois
