Study Notes
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.
