Notebooks Glossary

Notebooks are a web-based Jupyter IDE with shared persistent storage for long-term development and inter-notebook collaboration, backed by accelerated compute.


This glossary defines the core concepts behind Paperspace Notebooks to help build your mental model of how notebooks work and understand what the documentation is referring to when it uses certain terminology.

Continuous integration and continuous delivery/deployment (CI/CD) encompass several automated processes commonly performed in software development, such as building, testing, and deploying a software application. CI/CD reduces human intervention during the maintenance processes of software applications.
Compute Unified Device Architecture (CUDA) is an API created by NVIDIA for parallel computing.
A container is a single running instance of a service, worker, or static site resource that you have shipped on App Platform, and is in essence a live, runtime instance of an image (the artifact produced by the build process).
CPU
A central processing unit, also called a processor or CPU, is an essential piece of computer hardware that executes the instructions from a computer program.
Client URL (cURL) serves as a command-line tool and library for sending requests to and receiving responses from servers through network protocols. It is often used to troubleshoot or test responses from servers and APIs.
Daemon is a program performs system administration such as network communications, system monitoring, log management, and job scheduling in the background of Unix operation systems (OS).
Distributed Denial-of-Service (DDoS) attacks are a type of cyber-attack in which bad actors overwhelm servers, routers, load balancers, or applications with incoming connections to render them inaccessible.
An endpoint is a specific URL or network address that a client device or application uses to interact with a server or service. Most internet connected apps and websites communicate with endpoints to retrieve information, process user interactions, and perform other processes. For example, when you open a weather app on your phone, the weather app requests for the latest forecast information from a server endpoint.
An environment variable is a in-memory key/value pair that developers use to store configuration details about their app.
Ephemeral files are temporary files used for program execution and tasks.
An epoch is a single iteration through a dataset when training a machine learning model.
Gradient deployment allows machine learning models as a model as a service where the model is placed in a special container where the model performs the same way every time it is used.
A Gradient model is a scalable trained machine learning or deep learning model.
Gradient volume is a special storage for storing datasets, models, and project files. It allows users to keep track of data changes over time as well as saves backups of the data.
Graphcore offers specialized Intelligence P‌rocessing U‌‍nits (IPUs) that are designed specifically for artificial intelligence (AI) and machine learning (ML) computations. These IPUs handle heavy workloads that AI and ML require during processing and training and can process multiple tasks simultaneously in parallel.
Graphics Processing Unit (GPU) is a specialized processor meant to accelerate graphics rendering or processing complex mathematical calculations such as during machine learning training.
A handshake is the authentication process between two networked devices to ensure that both devices are who they claim to be.
A health check is a scheduled HTTP or TCP request that you can configure to run on a repeating basis to ensure that a service is healthy.
A hypervisor is a virtual machine monitor (VMM) that allows multiple operating systems to run simultaneously on one host computer.
A kernel is an intermediary component of an operating system that manages resources between the computer hardware and software.
Key
A key, or bucket key, is a unique data key for objects in a bucket.
Machine type is the set of virtualized hardware resources used for a virtual machine (VM) instance.
A network is a collection interconnected servers or computers that communicate and share resources amongst each other.
Network File System (NFS) is a distributed file system protocol that allows a user access to files within a computer over a network.
A notebook is a virtual environment where code is sequentially written and executed.
An Operating System Template or Machine is a disk image of a pre-designed or pre-configured version of a machine.
Persistent storage is a data storage within a device that retains the data even when the device is offline.
A port is a communication endpoint of a network connection. A port is identified using a port number for each transport protocol.
RAM
Random-Access Memory, or RAM, is a memory storage made to store and access memory on a short-term basis.
A runtime environment is an execution environment for deploying and running applications. Runtime environments contain the necessary applications, dependencies, and operating system to run an application. For example, when you create an app on App Platform, App Platform inspects the code and app resources, and then selects the appropriate runtime environment, such as Node, to run the app in.
S3-Compatible Object Storage, or S3 is a storage solution that uses the S3 API.
Software Development Kit (SDK) is a set of software tools and programs designed for a specific service or system.
SSH
SSH (Secure Shell Protocol) is a method to secure remote logins and communications from one computer to another which provides strong authentication and protects communication through strong encryption.
SSL certificate is a digital document outlining the identity of the website.
Symmetric ciphers use the same key for encrypting and decrypting data.
TLS
Transport Layer Security (TLS) is a security protocol focused on privacy and data security for communication across the internet.
Two-Factor Authentication (2FA) is a security method where the user uses two different authentication methods to verify their identity.
A virtual central processing unit, virtual processor, or vCPU is a physical CPU assigned to a virtual machine (VM).
A virtual machine, or VM, is a self-contained virtualization of an operating system.
Virtual Private Networks (VPN) are used create a private and secure connection to the public Internet.
In machine learning, a workflow is a set of processes working towards a certain objective.
