...Ex2.4.1 - click start, click run, type cmd or command and press enter. Review 1. ? 2. The CLI was the primary means of interaction with most computer systems until the introduction of the video display terminal in the mid-1960s, and continued to be used throughout the 1970s and 1980s on Unix systems and personal computer systems including MS-DOS, CP/M and Apple DOS. The interface is usually implemented with a command line shell, which is a program that accepts commands as text input and converts commands to appropriate operating system functions. Command-line interfaces to computer operating systems are less widely used by casual computer users, who favor graphical user interfaces. Command-line interfaces are often preferred by more advanced computer users, as they often provide a more concise and powerful means to control a program or operating system. Programs with command-line interfaces are generally easier to automate via scripting. Alternatives to the command line include, but are not limited to text user interface menus (see IBM AIX SMIT for example), keyboard shortcuts, and various other desktop metaphors centered on the pointer (usually controlled with a mouse). 3. In computing, graphical user interface (GUI,[1] sometimes pronounced "gooey" or "gwee")[2] is a type of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation, as opposed to text-based interfaces, typed command labels...

...Lab #10 Securing the Network with an Intrusion Detection System (IDS) Introduction Nearly every day there are reports of information security breaches and resulting monetary losses in the news. Businesses and governments have increased their security budgets and undertaken measures to minimize the loss from security breaches. While cyberlaws act as a broad deterrent, internal controls are needed to secure networks from malicious activity. Internal controls traditionally fall into two major categories: prevention and detection. Intrusion prevention systems (IPS) block the IP traffic based on the filtering criteria that the information systems security practitioner must configure. Typically, the LAN-to-WAN domain and Internet ingress/egress point is the primary location for IPS devices. Second to that would be internal networks that have or require the highest level of security and protection from unauthorized access. If you can prevent the IP packets from entering the network or LAN segment, then a remote attacker can’t do any damage. A host-based intrusion detection system (IDS) is installed on a host machine, such as a server, and monitors traffic to and from the server and other items on the system. A network-based IDS deals with traffic to and from the network and does not have access to directly interface with the host. Intrusion detection systems are alert-driven, but they require the information systems security practitioner to configure them properly. An IDS provides...

...Major Milestones of the Telecommunications Industry 1837 Samuel Morse invents the telegraph - The information age began with the telegraph, which was invented by Samuel F.B. Morse in 1837. This was the first instrument to transform information into electrical form and transmit it reliably over long distances. The earliest form of electrical communication, the original Morse telegraph of 1837 did not use a key and sounder. Instead it was a device designed to print patterns at a distance. 1858 Transoceanic telegraph cable is laid – The transoceanic telegraph cable is an undersea cable running under the Atlantic Ocean used for telegraph communications. The first communications occurred August 16, 1858, reducing the communication time between North America and Europe from ten days, the time it took to deliver a message by ship, to a matter of minutes. 1876 Alexander Graham Bell invents the telephone - The telegraph was followed by Alexander Graham Bell's invention of the telephone in 1876. The magneto-telephone was one of the first telephones on which both transmission and reception were done with the same instrument. 1885 - Incorporation of the American Telephone and Telegraph company (AT&T). After its incorporation in 1885, the American Telephone and Telegraph company dominated the telecommunications market. 1888 - Heinrich Hertz discovers the electromagnetic wave 1895 - Marconi begins experimenting with wireless telegraph 1901 Guglielmo Marconi invented the radio—the...

...Richard and Juliette Massey. He is a graduate of the public schools of St. Louis, Missouri and attended high school in University City, a suburb of St. Louis. After receiving a Harvard Book Award and a National Achievement Scholarship at University City High School, he entered Princeton University in 1973. There, he encountered his first real introduction to research mathematics in an honor calculus course taught by the late Ralph Fox. He wrote his undergraduate senior thesis, titled "Galois Connections on Local Fields,'' in algebraic number theory, under the direction of the late Bernard Dwork, and graduated from Princeton in 1977 with an A.B. in Mathematics (Magna Cum Laude, Phi Beta Kappa, and Sigma Xi). That same year he was awarded a Bell Labs Cooperative Research Fellowship for minorities to attend graduate school in the department of mathematics at Stanford University. In 1981, he received his Ph.D. degree from Stanford and his thesis, titled "Non-Stationary Queues,'' was directed by Joseph Keller. Dr. William Massey's parents, Juliette and Richard Massey Sr. were both educators; she was from Chattanooga, Tennessee and he was from Charlotte, North Carolina. They met at Lincoln University in Jefferson City, Missouri which became his birthplace. Professor Massey's initial fascination with numbers started when his mother would let him play with plastic numbers and cut up old calendars. His family moved to Saint Louis, Missouri when he was four. There he came of age educationally...

...Alcatel-Lucent is a global telecommunications corporation located in Paris, France. It has, under its wing, Bell Laboratories aka Bell Labs. They were previously known as AT&T Bell Laboratories and Bell Telephone Laboratories is now the research and development subsidiary of the French-owned Alcatel-Lucent. Over the past eight decades, Bell Labs R&D gave birth to new technologies and seminal scientific discoveries. (Alcatel Lucent, para 1) Elisha Grey and Enos N. Barton formed Western Electric Company in 1869. Both of them started a small manufacturing firm based in Cleveland, Ohio which was to become the largest electrical manufacturing company in America. In 1881, Alexander Graham Bell, an extraordinary leader of American Telephone & Telegraph (AT&T), purchased a controlling interest in Western Electric and made it the exclusive developer and manufacturer of all equipments for the Bell telephone companies. Now, the Bell system has provided much telephone services and support to America and Canada in the 1877 to 1984. It was then led by AT&T. In 1898, Compagnie Générale d'Electricité (CGE) was born, founded by a French engineer named Pierre Azaria. It was involved in business with several industries in Germany. Mainly it dabbled in electricity, transportation, electronics and telecommunications. CGE then rose up the ranks and became a leader in digital communications and would be known as well to produce train à grande vitesse – high speed trains in France. In...

...historically the communication industry has overwhelmingly been a monopoly. This was also true in the United States. As AT&T evolved from the late 19th century, except for a year as a nationalized company, existed as a national monopoly. In the so- called Progressive era of the 1910’s, the idea that a natural monopoly would be more efficient and economical than competing systems took hold. The idea of universal service, with rural rates being lower than urban rates (price discrimination). While never a “true” monopoly, with its substantial market share, and restrictions on connecting non-Western Electric equipment to its network, AT&T operated as one. The barriers to entry were primarily economic, the expensive right-of-way access and materials for wired connectivity being first among them. The restriction of un approved devices not being allowed on the AT&T network, limited interconnecting between competitors as well as additional connection & maintenance fees contributed to its dominance. As a monopoly, there were limited phone styles, and little need for deep price reduction through economy of scale or innovation, though state commissions regulated rates. The upside of the additional revenue, Bell Laboratories had been able to fund and develop technologies that are cornerstones of the modern society that are too numerous to mention here. It is debatable if these would have been developed as quickly without this reliable source of research funding....

...Unit 1 Research 1 PT1420 In the 1970s the programming language that was most popular was Pascal. Pascal was designed in 1968-69 but published in 1970. Niklaus Wirth created the Pascal language to “1) make available a language suitable for teaching programming as a systematic discipline based on fundamental concepts clearly by the language, and 2) to define a language whose implementations could be both reliable and efficient on then-available computers. In 1972 the C programming language was developed by Dennis Ritchie. C was created to work with the system Unix. “Unix gives C such advanced features as dynamic variables, multitasking, interrupt handling, forking, and strong, low-level, input-output. Because of this, C is very commonly used to program operating systems such as Unix, Windows, the MacOS, and Linux.” In the 1980s the popular programming language was C++. C++ was developed at Bell Laboratories. C++ is a general purpose multi-paradigm spanning compiled language that has both high-level and low-level languages’ features. It was started as an enhancement to the C programming language, Bjarne Stroustrup in 1979. In the 1990s Java was the popular programming language. It was created in 1991 developed by James Gosling at Sun Microsystems and release in 1995. In the 2000s Visual Basic (VB) was popular in the programming world. VB was developed from BASIC which was originally developed in 1964 by John Kemeny and Thomas Kurts. VB is a Microsoft programing language and software...
