MILESTONE TWO: NETWORKING AND DATABASE REPORT

MARCH 2023

Network Configuration refers to all communication designs within a network, which involves organizing hardware and software in a particular manner to achieve optimal performance. According to Techopedia (2019), a network configuration is a comprehensive process of configuring a network's controls, flow, and operation to support an organization's or network owner's communication needs. The all-encompassing term involves various processes of configuring and setting up the hardware, software, and other supporting equipment and components. The arrangement of hardware and software in a specific way based on this layout results in maximum efficiency. The network configuration involves a combination of hardware and software, where the hardware acts as a foundation for the network. The design can be limited to a local area or multiple locations worldwide.

The diagram below illustrates the organization's local network configuration based on a server-oriented network.

Fig.A: Network diagram

Server Based Networks

Large companies often prefer server-based networks as it is an ideal solution. A central server is established to store all the company's data in this network type. The central server gives access to authorized users and determines their access level. In addition, the data can be shared among users, and a backup is created on the server. This type of network is recommended when multiple users require access to server-based resources.

Figure A illustrates how the internet is connected to various departments and how data flows between different departments. Each network component plays a significant role in maintaining the data flow.

Internet/Cloud

"Cloud" is a term often used to describe the internet. Within the network diagram presented, the cloud refers to the Wide Area Network (WAN) available within the organization. A public or private WAN with a national or global reach can exist. The cloud serves as a reference point for the transfer of data, which may originate through one Internet Service Provider (ISP) or various ISPs. (Davis, 2019).

Routers

This device plays a vital role in a packet-switched network, such as the internet; sometimes, it can function as computer software. It determines the destination network point to the data packet that should be sent and acts as the first line of defense against network invasion. Routers are connected to other networks and select the direction of information packet transmission based on the present state of the connected networks. Routers connected to other network devices are typically connected through cables, and drivers are not required to operate in Windows or other operating systems (Fisher, 2019). They often function as Dynamic Host Configuration Protocol (DHCP) servers, particularly in smaller networks, and provide particular IP addresses.

Firewalls

This acts as a protective barrier between two networks and safeguards one from another. Per Cisco's definition, a firewall is a security device for monitoring incoming and outgoing network traffic and deciding whether to allow or block specific traffic based on specific security rules. A firewall acts as a protective barrier between two networks, guarding one network against another. It safeguards private networks in many businesses, and most firewalls offer data encryption to secure data traffic. (Cisco, 2019). For most companies, a firewall protects the private network from the public or shared network to which it is connected. Additionally, many firewalls offer encryption services to protect data traffic.

Servers

The server configuration involves a server responding to user or client requests. The server’s primary function is to provide access to users and employees, sharing data or software resources among them. Depending on the need, various servers exist, including database, game, and web servers. These servers are often regarded as the "brains" of network devices because they perform critical functions in managing the network's resources (Mitchell, 2018, p. 2).

Ethernets

The ethernet is the most widely used local area network (LAN) technology, which sets the wiring and signaling standards for the physical layer of TCP/IP. It falls under the Link Layer protocol within TCP/IP, which allows data to be sent or received between network devices on the same network segment. This is the standard means of connecting other devices, including computers, routers, and printers, over wired connections (Brand Media, 2018). In Ethernet connectivity, widgets search for available time slots to communicate within the network. Then, if no device is transmitting information, the waiting device can send the data.

Printers

A printer is a device that receives textual or graphical output from a computer and prints it onto paper. In the diagram above, all network devices, including departmental computers, are connected to the printer via an Ethernet link. The printer prints the data requested by any user in the respective departments (Rouse, 2016).

Other Components that should be included in the network.

Modems

The modem converts data from the analog form used on telephone lines to a digital format used on computers. While they are commonly used for connecting to the internet, they also have many applications in the corporate world, such as data transfer, remote management, and broadband backup. For example, remote management involves installing a modem at a prime location, allowing a particular application to be controlled or handled remotely without needing a physical visit. This can save a company time and money. Figure B shows the modem.

Fig.B: Modem

Network switches

This device connects different network devices using packet switching to send, receive, and process data to its intended devices. Advantageously, it forwards data to specific devices that require it rather than broadcasting to all other devices. This feature ensures that data is kept secure within an organization and is shared only among employees based on their access level. Fig. C. shows a network switch.

Fig.C: Network switch

Database Reports

The database provided has four tables, which include Computer Information. In a regular view, this table displays computer ID, employee ID, location, and whether the computer requires advanced software. The Design view reveals the data type for the computer and employee IDs in numbers.

Another table is Employee Information, which in regular view shows employee ID, last name, first name, office number, job title, and personal mobile number. The Design view shows that the data type for mobile numbers is currently in short text format but can be changed to number data type and saved.

The third table, Job Title, lists various job titles assigned to employees. Again, the job title data type is a short text in the Design view.

The fourth table, Upgrade Information, in the Design view shows that the data type for Upgrade Date is currently Text.

Since this data type is not suitable for a date and time format, it should be changed to Date/Time and saved. Then, in regular view, the column named "Upgrade Date" should be selected, and the dates of upgrading the OS for each group should be entered. After entering the dates, the data should be saved, and the table should be closed.

Figure 4 shows the updated Upgrade Information Table and the OS update dates for different groups.

Fig. D: Updated Information Table

Design view of the table

Fig. E: Design views of the upgrade updated table.

This table highlights the primary focus on the employee ID in Employee Information and the Computer ID in both Computer Information and Upgrade Information. By examining the table, one can gather various pieces of information, including the computer ID of the system scheduled for an update, the date of the update, the group number to which it belongs, and the name and ID of the employee using the system.

Milestone One: Programming Report

FEB 2023

Introduction

This report details the modifications made to the JavaScript code provided to display a message to employees regarding the upcoming operating system upgrade. The modifications were made to inform employees about the upgrade and to ensure a smooth upgrade process in each department. The code has been broken down into five components and each component's role in the programming process is explained. The code has been modified to display the days left until the upgrade for each group, starting from Group 1 with an initial upgrade date set at least 30 days in the future. The subsequent upgrade dates for Groups 2-5 have been set at 2, 5, 8, and 10 days after the initial upgrade date respectively. Screenshots have been included to support the changes made to the code.

Five components of the code that are significant are:

i. var today = new Date();: This line of code creates a new Date object that represents the current date and time.

ii. var upgradeDay = new Date("January 19, 2015");: This line of code creates a new Date object that represents a specific date. In this case, it's the date of the operating system upgrade.

iii. var msPerDay = 24 * 60 * 60 * 1000;: This line of code calculates the number of milliseconds in a day.

iv. var timeLeft = (upgradeDay.getTime() – today.getTime());: This line of code calculates the time difference between the current date and the upgrade date.

v. var daysLeft = Math.floor(days);: This line of code rounds down the number of days left until the upgrade to the nearest integer.

Pieces of code to be modified

1. Initial upgrade date that is at least 30 days in the future:

var initialUpgradeDate = new Date();

initialUpgradeDate.setDate(initialUpgradeDate.getDate() + 30);

2. Assigning dates for the other remaining groups:

var group2UpgradeDate = new Date(initialUpgradeDate);

group2UpgradeDate.setDate(group2UpgradeDate.getDate() + 2);

var group3UpgradeDate = new Date(initialUpgradeDate);

group3UpgradeDate.setDate(group3UpgradeDate.getDate() + 5);

var group4UpgradeDate = new Date(initialUpgradeDate);

group4UpgradeDate.setDate(group4UpgradeDate.getDate() + 8);

var group5UpgradeDate = new Date(initialUpgradeDate);

group5UpgradeDate.setDate(group5UpgradeDate.getDate() + 10);

3. Displaying massage to the employee

document.write("Your computer upgrade schedule:<br><br>");

document.write("Group 1: " + initialUpgradeDate.toDateString() + "<br>");

document.write("Group 2: " + group2UpgradeDate.toDateString() + "<br>");

document.write("Group 3: " + group3UpgradeDate.toDateString() + "<br>");

document.write("Group 4: " + group4UpgradeDate.toDateString() + "<br>");

document.write("Group 5: " + group5UpgradeDate.toDateString() + "<br>");
