Issues in Information Technology

My freshman year at Cornell University, I was sitting in a Computer Programming and Meteorology class when Professor Mark Wysocki(the New York State Climatologist) succeeded in attracting me to the study of computer graphic information systems through nothing more than a single sentence. He argued that, when a company adopts computer programming as the chief form of technology, it frees itself to pursue new boundaries, because new computer languages can always be created for each new problem.. I was immediately fascinated by the idea that the computer programming can alter individual lives, affect one's identity, and perhaps even shape national identity.

But how does it work? The internet, based on the concept of “packet switching”, involves the travelling of small packets of data over one or more networks (Frenzel, 2013). This can be compared to “electronic postcards”, meaning that “a computer generates a piece of data and flings it into the net, just like the postal system, except 100 million times faster” (Cerf, 2013). This concept allows one computer to speak to many different computers around the network by sending out these “electronic postcards”. However, before these networks can work seamlessly together, they must use a common protocol, or set of rules for transmitting and receiving these packets of data. There are several protocols currently in use, including the OSI Model, the TCP/IP Model, UDP, HTTP, and FDP (Mitchell, 2014), but the most commonly used is Transmission Control Protocol/Internet Protocol (TCP/IP) (Gilmer, 2011). Even as early as 1977, TCP/IP was being used by other networks to link to ARPANET (Kozierok,

TCP/IP is a protocol which transfers data across a network. It allows two different computers to communicate well even if they use different codes. Putting both computers into a new common code language which both computers

Computers in general give people the ability to complete tasks that would have taken days or weeks to complete with the clicks of a few buttons. As technologies continue to grow the amount of adjustments that will be needed to make will be astronomical. However, society is aiming to help people gain the skills needed to push mankind further. In Davidson’s essay, she discusses how computers and technology can be put to many applicable situations. While working with her students, the “Duke students came up with dozens of stunning new ways to learn [and] almost instantly students figured out that they could record lectures on their iPods and listen to them for leisure” (Davidson 52). This advancement took a few weeks at one college campus in the United States when the technology was still being developed. Now, students have adapted to begin working across the globe to further society with new ideas for applying these technologies. These students now work diligently to make technology as effortless as possible so that their programs will be what will be used in the future. Gilbert discusses how when people are judged by a panel of others they tend to feel worse about themselves but, when dealing with computers people are only judged by one computer which tells them

Transmission Control Protocol/Internet Protocol (TCP/IP) are the basic communication protocols, which were designed to provide low level support for internetworking. This term is generally also used to refer to a more generalised collection of protocols developed by the internet community and U.S. Department of Defence.

The two parts of the TCP/IP are the: Transport Layer Protocol and the Network Layer Protocol aka TCP and IP. TCP is what links the application layer to the network layer. It also helps by segmenting the data, by breaking them down

The Internet is, quite literally, a network of networks. It is comprised of ten thousands of interconnected networks spanning the globe. The computers that form the Internet range from huge mainframes in research establishments to modest PCs in people's homes and offices. Despite the recent hype, the Internet is not a new phenomenon. Its roots lie in a collection of computers that were linked together in the 1970s to form the US Department of Defense's communications systems. Fearing the consequences of nuclear attack, there was no central computer holding vast amounts of data, rather the information was dispersed across thousands of machines. A set of rules, of protocols, known as TCP/IP was

In The Mythical Man-Month the author, Frederick P. Brooks, Junior, starts off his tale of software engineering by giving the reader an image of prehistoric creatures—programs—struggling for survival against a tar pit. The fact is that programmers and their tools must be perfect in syntax and in reliability and every day a program is struggling to reach the requirements of today’s standards. He speaks of the skirmishes that surround the creation of a program such as putting forth time and effort only to discover that someone else has created a similar program, the possibility of a program becoming obsolete like that of a dinosaur in a tar pit, and the program’s innards and actions must be perfect. However, Brooks gives the reader a positive insight to programming by comparing it to a child’s imagination. He states, “He [the programmer] builds his castles in the air, from air, creating by exertion of the imagination.” (7)

The TCP/IP protocols are the heart and soul of the Internet, and they describe the fundamental rules that govern all communications in the network. The original address system of the Internet is Internet Protocol version 4 (IPv4). The Internet Engineering Task Force (IETF) developed IPv6 to deal with the long-anticipated problem of IPv4 address exhaustion. However, IPv6 is not foreseen to supplant IPv4 instantaneously.

“People think that computer science is the art of geniuses but the actual reality is the opposite, just many people doing things that build on each other, like a wall of mini stones”. (Knuth, 1968)

The two TCP/IP transport layer protocols (TCP and UDP), are very crucial for the smooth operation of network services for both the computer applications and application layer protocols such as HTTP, FTP, SMTP and Telnet. These two transport layer protocols TCP and UDP execute these services via the employment of IP. They use IP in the efficient routing of packets to their respective destination networks (Steinke,2001).The TCP is further noted by Steinke (2001) to be responsible for the provision of a reliable and yet connection-oriented byte-stream packet delivery while its counterpart UDP is noted to be responsible for the provision of a connectionless but rather unreliable packet delivery. In this paper we explain the work of the two TCP/IP transport layer protocols (TCP and UDP). In addition, describe how TCP and UDP manage key functions such as reliability, port addressing, and segmentation.

In this paper, we will analyze a few of the Information Systems/Technologies that are currently used by Workday and also, we will propose a couple of other Information Systems/Technologies that can be employed at Workday in future to further improve its performance.

All the computers, in the logically and physically networks have to follow the same rules known as Protocols such as TCP/IP, IPX/SPX and NETBEUI etc. Today, there are many computer networking technologies such as LAN, MAN, WAN, WLAN, ISDN, ATM, Frame Relay, X.25, Bluetooth,
