SSL and TLS are protocols used for securing the communication between web browsers and web servers. SSL stands for Secure Sockets Layer, while TLS stands for Transport Layer Security. TLS is an updated and more secure version of SSL, and it has since replaced SSL as the industry standard protocol for secure communication over the internet. Both SSL and TLS provide a secure and encrypted connection, which helps to protect sensitive data such as login credentials, credit card numbers, and other personal information from being intercepted by unauthorized parties. They use a combination of public and private keys to encrypt data transmitted between the web browser and the web server.


A subnet, short for subnetwork, is a portion of a larger network that is divided into smaller, more manageable network segments.Subnets are created by using a subnet mask, which is a 32-bit value that is used to identify the network portion and host portion of an IP address. The subnet mask is applied to an IP address to determine which bits represent the network portion and which bits represent the host portion.By creating subnets, network administrators can better manage network traffic, improve network security, and allocate IP addresses more efficiently. Subnets can be used to isolate specific parts of a network, create logical groupings of devices, or to control access to network resources.Subnets can be connected to each other through routers, which allow devices on one subnet to communicate with devices on another subnet. This enables larger networks to be divided into smaller, more manageable segments that can be more easily maintained and secured.


A subscription is a service agreement between a customer and a cloud computing provider that enables the customer to use the provider's services and resources. In a subscription, the customer pays a fee for access to the cloud provider's services for a specified period, typically monthly or annually.Subscriptions are a common pricing model used by cloud computing providers, such as Microsoft Azure and Amazon Web Services (AWS), and are typically based on the amount of resources used or the level of service required.Subscriptions typically provide users with access to a range of cloud services, such as virtual machines, storage, and networking. They can also include additional services such as support, training, and consulting.Subscription-based models offer several benefits, such as:

  1. 1.Cost-effectiveness: Subscriptions can be more cost-effective than traditional licensing models, as users only pay for what they use.

  2. 2.Scalability: Subscriptions enable users to easily scale up or down their usage of cloud services, allowing them to match their needs with their budget.

  3. 3.Flexibility: Subscriptions offer users flexibility, as they can select the specific services they need and adjust their usage as necessary.

  4. 4.Predictability: Subscriptions provide users with predictable costs, enabling them to budget and plan more effectively.

In summary, a subscription is a flexible and cost-effective way to access cloud computing resources and services, allowing businesses of all sizes to leverage the power and benefits of cloud computing.


A networking device that connects devices on a local area network (LAN) and forwards data between them. Switches are used to create a LAN and improve network performance.
