Q & A

What are the three main cloud computing service models discussed?

The three main cloud computing service models discussed are: Infrastructure as a Service (IaaS), Software as a Service (SaaS), and Platform as a Service (PaaS).

How can network performance be optimized?

Network performance can be optimized by improving bandwidth through logical routing of pathways and mediums, updating device drivers and firmware, monitoring traffic flows, and implementing flow scheduling.

What is the purpose of graph and network theory in social networking?

Graph and network theory in social networking aims to map out the connections between different users, pages, and groups to portray the flow of information through the network.

What are some examples of biometric authentication?

Some examples of biometric authentication are facial recognition, fingerprint scanning, retina scanning, and voice recognition.

What is a TPM chip used for in terms of security?

A TPM (Trusted Platform Module) chip is used to support security measures like secure system booting and checking digital signatures to ensure they are coming from trusted locations.

What causes transmission interference in networks?

Factors like distance between nodes, network topology, physical barriers like buildings and cliffs, and environmental factors can all cause interference in network data transmission.

How do software updates improve security?

Software updates often contain security patches that fix vulnerabilities and add new protections against emerging cyber threats.

What is the purpose of CAPTCHA tests?

CAPTCHA tests are designed to distinguish human users from bots by presenting a challenge that is easy for humans but difficult for bots to interpret.

What are some examples of disruptive technologies?

Some examples of disruptive technologies include the internet, smartphones, cloud computing, artificial intelligence, and cryptocurrencies.

How does remote working technology support accessibility?

Remote working technology like video conferencing, file sharing, and cloud platforms support accessibility by enabling people with disabilities to more easily participate without needing to physically go to a workplace.
