Analyze the necessity for different protocols in wireless communications. An agreed upon guidelines or set of rules for communication is called as protocol. It is very important to agree upon some communication rules otherwise it will fail. If one party speaks French and the other German the communication would surely fail. If they both agree on a single language they can communicate successfully. The set of communication use don internet is called as TCP/IP. A protocol can be defined as rules

Checkpoint - TJX Companies IT/205 March 1, 2013 Checkpoint - TJX Companies This week’s checkpoint deals with the credit card data theft at TJX companies which occurred in July of 2005. According to the book Essentials of MIS, the thieves used a vulnerable wireless network from one of the department stores on the TJX network to gain access. (Laudon & Laudon, 2011, p. 243) After the thieves had access to the network the installed a sniffer program on one of the main computers of the network

A typical wan transmission speed is 1mbps. A business cannot use the internet unless it goes through an isp. True A device attached to a network is called a host. A host address on an internet is its ip address. A lan is a network that provides service within a site. A packet is called a packet in a routed network Different isps interconnect at network access points. For human reading ip address usually are expressed in dotted decimal notation. Multiplexing reduces the cost of trunk lines

IEEE standards have a comprehensive listing of working groups but not all have public viewable websites. I will focus on the Information Technology working group with the sub-directory of Software and Systems Engineering. The IEEE Computer Society is the largest association for computer professionals in the world and was founded more than 50 years ago. The Software

Kimberly Pulda MIS 589 Week 4 You Decide To me there are a few important issues that need to be addressed. The first issue that needs to be fixed is from John Fischer. He states that his laptop operates at 10 megabits. That is really slow especially since it should have been running at 100 megabits. I would fix this by using a Category 6 UTP 1000 Base F Ethernet because it increases the maximum data transfer rate a hundredfold. For example it will take it from 10 megabits to 1 gigabyte per

The difference is that in a BBS uses one AP to create one wireless LAN while an ESS uses more than one AP to create one wireless LAN.
