Cloud Computing and ICTs Overview

Cloud Computing

• Delivers computing services such as storage, processing, and applications over the internet (the cloud).
• Allows for scalability, as resources can be adjusted based on demand.
• Services are typically categorized into three models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).

Key Components of a Computer's Cooling System

• Air cooling uses fans and heat sinks to dissipate heat from components like CPUs and GPUs.
• Liquid cooling circulates coolant through tubes to absorb heat, often providing more efficient cooling than air systems.

IP Address

• A unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication.
• Facilitates identification and location of devices on the network.

Social Impacts of ICTs

• Enhances communication and connectivity globally, bridging geographical barriers.
• Influences job opportunities and the nature of work, leading to shifts in labor markets.
• Can exacerbate inequalities, with disparities in access to technology and information.

Function of a Uniform Resource Locator (URL)

• Acts as an address used to access resources on the internet, directing browsers to specific web pages.
• Contains several components including protocol (e.g., HTTP, HTTPS), domain name, and path to the resource.

Quiz 5: Study Notes

• Air Cooling and Liquid Cooling

  • Air cooling relies on airflow generated by fans to exchange hot air with cooler air.
  • Liquid cooling involves pumps to move coolant past heated components, removing heat more effectively.

• System Software

  • Software designed to manage and control computer hardware and provide a platform for application software.
  • Includes operating systems and utilities that help manage system resources.

• Purpose of a Firewall

  • Acts as a security barrier between a trusted network and untrusted networks, controlling incoming and outgoing traffic.
  • Prevents unauthorized access and protects the computer from malware and other threats.

• Domain Names and IP Addresses Relation

  • Domain names are human-readable addresses linked to numeric IP addresses through the Domain Name System (DNS).
  • Facilitates easier access to websites without memorizing complex numeric addresses.

• Determining a Computer's Hardware Specifications

  • Check system information through operating system tools (like Device Manager on Windows or About This Mac on macOS).
  • Use third-party software to provide detailed reports on components such as CPU, RAM, storage, and GPU.
