ITF+ Infrastructure Terms Flashcards

The CPU (Central Processing Unit) is the primary component of a computer that performs most of the processing inside a computer.

"Cloud computing is the delivery of computing services (including servers, storage, databases, networking, software) over the internet ('the cloud')."

"A data center is a facility used to house computer systems and associated components, such as telecommunications and storage systems."

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.

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.

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.

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.

"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."

"A virtual machine (VM) is a software-based emulation of a computer, running an operating system and applications just like a physical computer."

DNS (Domain Name System) is a system that translates human-readable domain names (like www.example.com) into IP addresses that computers use to identify each other on the network.

A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules.

"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."

IaaS (Infrastructure as a Service) is a cloud computing service model that provides virtualized computing resources over the internet.

"SaaS (Software as a Service) is a cloud computing service model that delivers software applications over the internet, on a subscription basis."

"A router is a networking device that forwards data packets between computer networks, directing traffic on the internet."

"Virtualization is the creation of a virtual version of something, such as a hardware platform, operating system, storage device, or network resources."

A wireless access point (WAP) is a networking hardware device that allows Wi-Fi devices to connect to a wired network.

"Network segmentation is the practice of dividing a computer network into smaller parts, or segments, to improve security and performance."

A switch is a networking device that connects devices within a network and uses packet switching to forward data to its destination.
