# Glossary ### Datacenter A datacenter is a secured location where servers and GPUs are hosted. Sesterce is present [**within a large number of world class and ultra-safe datacenters**](https://www.sesterce.com/datacenters) to ensure the data security of its customers and ensure performances of its Pods. ### GPUs A GPU (Graphics Processing Unit) is a specialized processor designed to accelerate graphics rendering and data-intensive computations. It excels in parallel processing, making it ideal for tasks like gaming, graphics design, and deep learning. 👉[**Discover how to choose your GPUs within Sesterce Cloud!**](/compute-instances.md#how-to-display-gpus-available) ### Pod, instance Pods are composed by a certain number of GPUs, plus memory (RAM), a non-persistent storage space (container disk) and possibly a Volume (persistent storage space). ### Secured cloud Secured cloud refers to cloud computing environments that are protected by robust cybersecurity measures which ensure that data and applications hosted in the cloud are safeguarded from unauthorized access and threats. ### vRAM VRAM, or Video Random Access Memory, is a type of specialized memory used by GPUs to store image data for processing. In a way, it's your gpu's memory. ### Dataset A dataset refers to a structured collection of data that is processed and analyzed using GPUs. These datasets are typically large and complex, making them ideal for machine learning, deep learning, and other data-intensive tasks that benefit from the parallel processing capabilities of GPUs. ### Image Template Refers to a pre-configured virtual machine image that includes a specific operating system and installed software, optimized for GPU tasks. These templates provide a ready-to-deploy environment. 👉 [**Learn more about image templates in Sesterce Cloud!**](/compute-instances.md#image-configuration) ### Volume A volume is a block storage unit attached to cloud instances for storing data. Volumes are scalable, persistent storage resources that can handle the high-throughput and low-latency requirements essential for GPU-intensive tasks, such as machine learning and data processing. 👉[ **Learn more about volumes in Sesterce Cloud!**](/compute-instances.md#get-a-volume) ### SSH Key Cryptographic key used for secure access to cloud instances equipped with GPUs. It ensures a secure, password-less login to manage and operate GPU-intensive tasks remotely, enhancing security by eliminating the risks associated with password-based authentication. 👉 [**Learn more about SSH keys in Sesterce Cloud!**](/compute-instances.md#how-to-add-a-ssh-key) ### Top Up balance The top-up balance is the credit balance allocated to the user's account 👉 [**How to refill credits on Sesterce Cloud?**](/welcome-on-sesterce-cloud/payment-and-billing.md) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
