Question 2

What are the advantages and disadvantages of host-based networks versus client-server networks? Explain two major benefits and/or limitations of client-server networks compared to host-based networks.

Accepted Answer

Host-based networks and client-server networks each have their own advantages and disadvantages.

One major advantage of client-server networks compared to host-based networks is centralized management. In a client-server network, all resources and data are stored on a central server, making it easier to manage and secure the network. This centralized approach also allows for easier backup and recovery of data, as well as easier implementation of security measures such as firewalls and antivirus software.

Another benefit of client-server networks is scalability. Client-server networks can easily accommodate a growing number of users and devices by adding more servers or upgrading existing ones. This scalability is important for businesses and organizations that need to expand their network infrastructure as they grow.

However, client-server networks also have limitations. One major disadvantage is the cost of implementation and maintenance. Setting up and maintaining a client-server network can be expensive, as it requires dedicated servers, networking equipment, and IT staff to manage and maintain the network.

Another limitation of client-server networks is the potential for single points of failure. If the central server experiences a hardware or software failure, it can disrupt the entire network and cause downtime for all users. This risk can be mitigated with redundant servers and backup systems, but it adds complexity and cost to the network infrastructure.

In contrast, host-based networks have the advantage of simplicity and lower cost, as they do not require dedicated servers and can be set up using existing hardware. However, they lack the centralized management and scalability of client-server networks, making them less suitable for larger organizations or businesses with growing network needs.

Question 3

What is cloud computing and how is it useful?

Accepted Answer

Cloud computing refers to the delivery of computing services, including servers, storage, databases, networking, software, and analytics, over the internet. It allows individuals and businesses to access and use these services on a pay-as-you-go basis, without the need to invest in and maintain physical infrastructure.

Cloud computing is useful in several ways. Firstly, it offers flexibility and scalability, allowing users to easily scale their resources up or down based on their needs. This means that businesses can quickly adapt to changing demands without having to invest in new hardware or software.

Secondly, cloud computing offers cost savings, as users only pay for the resources they use. This eliminates the need for large upfront investments in hardware and software, as well as the ongoing costs of maintaining and upgrading them.

Additionally, cloud computing enables remote access to data and applications, allowing users to work from anywhere with an internet connection. This can improve productivity and collaboration, as well as provide disaster recovery and business continuity benefits.

Overall, cloud computing provides a more efficient and cost-effective way to access and manage computing resources, making it a valuable tool for individuals and businesses alike.
