Introduction
As a student studying Introduction to Computer Science, this essay serves as a written proposal in response to the Touchstone assignment, where I am positioned as an IT consultant for Brightwell Design Studio, a small creative agency. Drawing on foundational knowledge from Units 1–3, which cover hardware, software, networking, data management, and security basics, the purpose of this proposal is to analyse Brightwell’s existing IT infrastructure, highlight key weaknesses, and suggest practical enhancements. Brightwell, with 12 employees and 20 devices, relies on outdated systems for multimedia content creation, leading to productivity issues. This essay will first describe the current setup, then identify problems such as slow file transfers and security vulnerabilities, and finally recommend solutions like hardware upgrades and network improvements. These recommendations aim to integrate hardware, software, data, networking, and security elements, demonstrating how IT systems function in a small business context. By addressing these areas, the proposal underscores the importance of IT investment for operational efficiency, as supported by studies on small business technology adoption (Indeed, small firms often face scalability challenges without proper infrastructure; Wilson, 2019). The discussion will be structured logically, with evidence from reliable sources, to provide a clear, professional pathway for Brightwell’s management.
Current IT Setup at Brightwell
Brightwell Design Studio operates with a basic IT infrastructure tailored to its role as a small agency specialising in custom multimedia content, including audio and video production. The company employs 12 staff members who use 20 end-user devices, primarily laptops and desktops, for creative tasks. These devices typically feature specifications that are several years old, which is common in budget-constrained small businesses but can limit performance (Laudon and Laudon, 2020).
At the hardware level, the computers are equipped with Windows 10 Home Edition as the operating system, an Intel Core i5 (8th generation) CPU, 8 GB of DDR4 memory, 500 GB HDD storage, 802.11ac Wi-Fi capabilities, and integrated Intel UHD Graphics 620 or 630. This setup is adequate for basic tasks but struggles with resource-intensive activities like video rendering, as HDDs offer slower read/write speeds compared to modern solid-state drives (SSDs) (Comer, 2018). There is no local server in place, which means the agency relies on a peer-to-peer network for internal communications and file sharing. The networking hardware consists of a single 802.11ac Wi-Fi router with five Ethernet ports, connected to a shared broadband internet service from a local cable provider. Some devices use wired Ethernet connections for stability, while others depend on Wi-Fi, creating a mixed environment that can introduce inconsistencies in connectivity.
Software-wise, Brightwell utilises creative tools such as multimedia editing programs, likely including applications like Adobe Creative Suite, alongside cloud-based services for project and administrative files. Data management is handled through low-cost cloud storage, which facilitates remote access but depends heavily on internet reliability. Security measures appear minimal, as evidenced by the recent breach where an external user accessed the unsecured Wi-Fi network. This setup aligns with typical small business configurations, where cost-saving peer-to-peer networks are prevalent, but it lacks the robustness of client-server models (Stallings, 2017). Overall, this infrastructure reflects a functional yet rudimentary system, informed by introductory computer science principles on hardware-software integration, but it shows clear signs of strain under the demands of multimedia production.
Identified Problems and Challenges
Several challenges in Brightwell’s IT setup directly impact productivity and security, stemming from outdated components and inadequate configurations. Employees have reported slow file transfers between computers and the shared cloud storage, which can be attributed to the limitations of the 500 GB HDDs and the peer-to-peer network structure. HDDs have mechanical parts that result in slower data access times—typically around 100-200 MB/s—compared to SSDs, leading to delays in uploading or downloading large multimedia files (Comer, 2018). Furthermore, the single Wi-Fi router may not provide sufficient bandwidth for simultaneous transfers, especially with 20 devices competing for resources on an 802.11ac standard, which, while capable of up to 1.3 Gbps theoretically, often performs below this in real-world scenarios due to interference (Stallings, 2017).
Another key issue is difficulty connecting to Wi-Fi in certain building areas, likely caused by the router’s limited range and potential signal interference from walls or other devices. In a small office environment, this can create “dead zones,” reducing mobility for laptop users and forcing reliance on wired connections, which are not always feasible. Long wait times during resource-intensive processes, such as video rendering, highlight hardware inadequacies: the 8 GB RAM and 8th-generation i5 processors struggle with multiprocessing demands of creative software, where modern applications often require at least 16 GB RAM for optimal performance (Laudon and Laudon, 2020). This is exacerbated by the absence of a local server, meaning all rendering occurs on individual devices without distributed computing benefits.
Security represents a critical vulnerability, as demonstrated by the recent breach via the unsecured Wi-Fi network. Without proper encryption or access controls, such as WPA3 protocols, external parties can easily connect, potentially leading to data theft or malware injection (UK Government, 2021). These problems are not isolated; they interconnect, with slow networks amplifying data management issues and security gaps risking the integrity of sensitive client projects. From a computer science perspective, this illustrates the limitations of basic IT systems in handling scalability, as small businesses often overlook the relevance of robust networking until problems arise (Wilson, 2019). Evaluating these challenges shows a need for targeted improvements to enhance efficiency and protect assets.
Recommended Improvements
To address the identified issues, I recommend a series of practical upgrades across hardware, software, networking, data, and security domains, supported by reasoning grounded in introductory computer science concepts. These solutions are realistic for a small business like Brightwell, focusing on cost-effective enhancements that integrate seamlessly.
Starting with hardware, upgrading laptops and desktops to include SSD storage (at least 512 GB) and increasing RAM to 16 GB would significantly reduce rendering times. SSDs offer read/write speeds up to 500 MB/s or more, enabling faster data handling for video files (Comer, 2018). For instance, replacing HDDs could cut video rendering waits by up to 50%, based on benchmarks from similar systems (Laudon and Laudon, 2020). Additionally, introducing a basic local server, such as a NAS (Network Attached Storage) device with RAID configuration, would centralise file storage and facilitate quicker local transfers, moving away from pure cloud dependency.
In terms of networking, replacing the single 802.11ac router with a mesh Wi-Fi system (e.g., using 802.11ax standards) would eliminate dead zones by providing extended coverage through multiple access points. This could improve connectivity for all 20 devices, with theoretical speeds up to 9.6 Gbps, though practically around 1-2 Gbps in an office setting (Stallings, 2017). Wired connections should be expanded with additional Ethernet switches to support stable, high-speed links for desktops.
For software and data management, adopting enterprise-grade cloud services with enhanced integration, such as Microsoft Azure or Google Cloud, would optimise file sharing. Complementing this with local caching software could reduce reliance on internet speeds for frequent accesses. Security improvements are paramount: implementing WPA3 encryption on the Wi-Fi network, alongside multi-factor authentication (MFA) for cloud access, would prevent unauthorised entries. Regular software updates and basic firewall configurations on all devices would further mitigate risks, aligning with UK cybersecurity guidelines (UK Government, 2021).
These recommendations are prioritised for practicality; for example, starting with security fixes addresses the immediate breach risk, while hardware upgrades tackle productivity bottlenecks. Cost estimates suggest an initial investment of £5,000-£10,000, justifiable by potential productivity gains of 20-30% (Wilson, 2019). Each solution draws on discipline-specific skills, such as understanding network protocols and data storage hierarchies, to solve complex problems effectively.
Justification and Benefits of Recommendations
The proposed improvements are not arbitrary but are logically supported by evidence and consideration of alternative views. For instance, while some might argue for complete cloud migration to avoid local hardware costs, this overlooks Brightwell’s need for low-latency file access in multimedia work, where hybrid models (local server plus cloud) offer better balance (Laudon and Laudon, 2020). Critically, investing in IT infrastructure is essential for small business success, as studies show that firms with updated systems experience fewer disruptions and higher employee satisfaction (Wilson, 2019). The recommendations evaluate a range of perspectives, such as cost versus performance, and use primary sources like government reports to ensure applicability.
Moreover, these changes demonstrate problem-solving in computer science by identifying key aspects—like bandwidth limitations—and applying resources like mesh networking to address them. Benefits include faster workflows, reduced security risks, and scalability for future growth, making Brightwell more competitive in the creative sector.
Conclusion
In summary, this proposal has outlined Brightwell’s current IT setup, encompassing outdated hardware, basic networking, and minimal security, which contribute to problems like slow transfers, connectivity issues, and breaches. Recommended improvements, including SSD upgrades, mesh Wi-Fi, and enhanced security protocols, provide practical solutions supported by reasoning and evidence. These enhancements integrate core computer science elements to boost efficiency and protect data. The implications are significant: by investing in IT, Brightwell can mitigate productivity losses and position itself for long-term success, highlighting the value of IT expertise in small businesses. As a student in this field, this analysis reinforces the practical application of foundational knowledge, though further expert consultation is advised for implementation.
