Description

Programming Some of the key components of the code include the class identifier, the calendar code, the semicolon, and the “system.out.printIn” command string. The class code defines the type of class for the code. A JavaScript class is a type of function. Classes are declared with the class keyword. We will use function expression syntax to initialize a function and class expression syntax to initialize a class (Raschia, 2018). The calendar code provides a means of converting the date of a specific point in time and calendar fields such as DAY, MONTH, YEAR, HOUR, and MINUTE. Since this code is an Abstract class, a constructor cannot be used. SO, a static method “Calendar.getinstance()” is used to represent and create a sub-class. The calendar code in this code Java program uses a concrete subclass called “GregorianCalendar”. This subclass of a “Calendar” uses the most commonly sed Gregorian Calendar; this is the one that is most familiar to people. (GeeksforGeeks.com, 2018) The semicolons that are found in this program are used to end a line of code (statement). When placing a semicolon, there should be no other characters found on the line of code after the semicolon, unless they create another statement that also ends with a semicolon and follows the syntax of the program. Semicolons can break the script if placed in the wrong place. Adding of the second line that states, “Welcome to Swagger Distribution!” is designed to display an additional message on the screen. Moving the “Welcome” message above the date creates a smoother syntax for the program. Changing “Current” to “Today” creates a more polite greeting message.

Networking

A T1 line is used to connect the Wide Area Network (WAN) to the Local Area Network (LAN). It connects to the T1 Demarcation Router, which is designed to have the appropriate interface for the T1 line. The T1 router then connects to the main router. This router will provide network connectivity to all of the clients. Prior to connecting directly to the network, the connection is routed through a Private Internet Exchange (PIX) firewall. This firewall is designed to cloak the entire LAN from the outside world. The connection the runs to the Ethernet Switch. An ethernet switch is designed to “split” one ethernet connection into several. The way it works is that you connect an ethernet line from the router to one of the ethernet ports on the switch, then connect

the first-tier downstream clients to the other ports on the switch. The two servers, the cross-patch panel, and the fiber optic connection to the warehouse are the first-tier clients. Once the main architecture of the network is created, the network is then branched out to other clients. The patch panel then connects to the various ethernet ports throughout the offices. If you want to set up a wired network that includes multiple wall ports in various rooms, a patch panel in a central location can provide a simple, neat and easy-to-manage solution. So, what is a patch panel you ask? A patch panel is essentially an array of ports on one panel. Each port connects, via a patch cable, to another port located elsewhere in your building (firefold.com, unk date). Ethernet cables then run from the cross-patch panel to the individual wall plates. An ethernet cable from the wall plate to the client connects the client to the network. On the other side of the network, a fiber optic cable is run to the shipping office in the warehouse, which is a remote location. The fiber optic cable then terminates at a remote ethernet switch in the warehouse office. From the remote switch, ethernet cables are run to the individual wall plates in order to connect each workstation to the network via an ethernet cable.
