ITF+ Infrastructure Terms Flashcards

Explain what a motherboard is."A motherboard is the main printed circuit board (PCB) in a computer that connects and allows communication between various components such as the CPU, RAM, and storage devices."
What is a hard drive?A hard drive is a data storage device used for storing and retrieving digital information using one or more rigid rapidly rotating disks coated with magnetic material.
What is virtualization?"Virtualization is the creation of a virtual version of something, such as a hardware platform, operating system, storage device, or network resources."
What is a CPU?The CPU (Central Processing Unit) is the primary component of a computer that performs most of the processing inside a computer.
Explain SaaS."SaaS (Software as a Service) is a cloud computing service model that delivers software applications over the internet, on a subscription basis."
Define IaaS.IaaS (Infrastructure as a Service) is a cloud computing service model that provides virtualized computing resources over the internet.
What is a modem?A modem is a hardware device that converts data from a digital format to an analog format (and vice versa) for transmission over telephone lines or cable.
What is an IP address?An IP address is a unique string of numbers separated by periods that identifies each computer using the Internet Protocol to communicate over a network.
Define a VPN.A VPN (Virtual Private Network) is a service that encrypts your internet connection and hides your online activity from third parties.
Explain what DNS is.DNS (Domain Name System) is a system that translates human-readable domain names (like into IP addresses that computers use to identify each other on the network.
What is a firewall?A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules.
What is cloud computing?"Cloud computing is the delivery of computing services (including servers, storage, databases, networking, software) over the internet ('the cloud')."
Define RAM.RAM (Random Access Memory) is a type of computer memory that can be accessed randomly and is used for storing working data and machine code currently being used.
Define a virtual machine."A virtual machine (VM) is a software-based emulation of a computer, running an operating system and applications just like a physical computer."
What is network segmentation?"Network segmentation is the practice of dividing a computer network into smaller parts, or segments, to improve security and performance."
Explain what a data center is."A data center is a facility used to house computer systems and associated components, such as telecommunications and storage systems."
What is a router?"A router is a networking device that forwards data packets between computer networks, directing traffic on the internet."
Define a switch in networking.A switch is a networking device that connects devices within a network and uses packet switching to forward data to its destination.
What is PaaS?"PaaS (Platform as a Service) is a cloud computing service model that provides a platform allowing customers to develop, run, and manage applications without dealing with the infrastructure."
Explain a wireless access point.A wireless access point (WAP) is a networking hardware device that allows Wi-Fi devices to connect to a wired network.
