1. What changes does FTP make to an ASCII file when you download it in ASCII mode to a windows machine from a Linux server? What changes are made when you download the file to a Mac?
Unix, Linux, etc uses only a line feed at the end of each line. So transferring to a Window will add a carriage return to each line.
New Mac's are Linux-based, transferring from a Linux to a Mac shouldn't change anything.
2. What happens if you transfer an executable program file in ASCII mode?
The file will be corrupted: Any bytes that match a NEWLINE will be altered, resulting in a program that will not execute properly.
3. When would FTP be a better choice than SFTP?
When downloading public files
4. How would you prevent a local

9. After downloading a file, you find out that it doesn’t match the MD5 checksum provided. Downloading the file again gives the same incorrect checksum. What have you done wrong and how would fix it?
It can be a few different things, maybe the file was corrupted. It could also be the site where you downloaded it from. It could be the different settings you have set for SFTP were not allowing you to download.
10. How would you configure vsftpd to run through xinetd, and what would be the main advantage of this approach?
To configure vsftpd to run through xinetd, set listen=NO in
/etc/vsftpd/vsftpd.conf, and create an xinetd configuration file for vsftpd in /etc/xinetd.d. This configuration allows you to provide finer-grained access control to the server.

Professionals working in the higher education industry face a set of new trials stemming from advances in technology, and a new breed of technically capable students that challenge the status quo of traditional classroom methods of teaching (Philbin, 2013). This technology, known as information and communication technologies (ICT), allows universities to deliver personalized learning experiences through mobile devices and the internet (Bell & Federman, 2013; Philbin, 2013). Adopting, integrating, and successfully using ICT in higher education institutions presents a challenge, as the transient nature of technology adds a difficulty for some higher education professionals to manage and incorporate technology successfully (Amirault, 2015). As such, the difficulty experienced stimulate feelings of uncertainty and skepticism, which lead to technology related stress (Bradshaw & Zelano, 2013). Technology related stress, also known as technostress, is a term describing the anxiety, uncertainty, and insecurity felt, engendered by the utilization or perceived ease of use of technology. This facet of stress hinders individual and organizational productivity (Brod, 1982). Researchers estimated that U.S. organizations lose approximately $650 billion each year because of technostress (Galluch, Grover, & Thatcher, 2015). Although past research linked job stress with job satisfaction (Oshagbemi, 2013; Schubert-Irastorza & Fabry, 2014), the connection between technostress in particular with

23. What type of encryption protocol does Secure FTP (SFTP) use to secure FTP transmissions? A variation of the SSH (Secure Shell Protocol)
The task was seemingly straightforward; create a piece of writing without using a single form of technology. I didn’t think this would be much of a problem. I figured I could hand-write something instead of typing it or using a word processor and that would meet the requirements of the project. However, according to Dennis Baron in his essay From Pencils to Pixels the pencil is, in fact, a form of technology. Evidently, it was invented “by joiners, woodworkers specializing in making furniture, to scribe measurements for wood” (Tribble/Trubek, 42). Adding further to my obstacles, paper, being a created object, was not an option as well. This was turning out to be harder than I thought. After I pondered and
It is generally accepted that information is a vital commodity for the successful operation of today’s organizations. Nowadays modern business organizations are using computerized information systems in order to obtain such information. However as the technology advances rapidly the main issue is how can an organization should effectively use such an information system - which its management sometimes can be unpredictable - in order to effectively help the whole organization structure to improve and take the most out of it.
Information technology is a rapidly growing part of today's society. It affects everyone's life in many aspects. Every human endeavor is influenced by information technology and the increasing rate at which what it can perform includes. One area of human endeavor that information technology has greatly influenced is the practice of medicine, specifically veterinary medicine. Not only has veterinary medicine been influenced by information technology, it has also been enhanced by it. The degree to which the practice of veterinary medicine includes information technology is observable at the Animal Emergency Clinic of Central New York on Erie Blvd. in Syracuse, New York.

Knowledge has increased tremendously in all areas of human endeavor with new discoveries and better ways of communication and interaction emerging all over the world. The rapid development of information, communication and technologies (ICT), internet technologies and Web-based applications have initiated unparalleled transformation in universities all over the world (Cheng & Yau, 2010). This has brought about increased demand for information and the need for “education for all”. Advances in computer and telecommunication technology, World Wide Web has become a major factor to reckon with in searching for and dissemination of information (Sanjo, 2005). These advances has brought about an “e” in all human endeavor; e-learning, e-banking, e-government. The advent of ICT devices has revolutionized the nature of human activities and operation in virtually all fields of endeavor.

At present, “Information Technology (IT) is a very essential part of our life. The processing of data is done by a computer with the help of hardware and software technology. “Information Technology has become a major driving force in many organizations” . To sell their products and services successfully these organizations require IT applications. For example, Companies are utilizing the internet for transferring data faster and performing different exercises to accomplish productivity. Companies like “amazon.com” using internet service to sell their products efficiently. The Internet has influence over many sectors like business and education. In
The use of Information and communication technology (ICT) for language practice has a long history, and mobile learning launched when the first project to use mobile phones in language learning which was developed by the Stanford Learning Lab to help Spanish learners (Brown, E, 2001). Today the communication technology has become one of the necessities of modern learning and communication, for instance most Chinese schools and classrooms set up groups to sending their announcements, and multimedia to students on widespread social mobile applications to communicate and sharing audio, photos, videos it is called (WeChat) and it has more than 800 million users all over the world (Lien, C. H. and Y. Cao, 2014).
