AcronymDefinition
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.
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.
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.
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 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 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.
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.
What is cloud computing?"Cloud computing is the delivery of computing services (including servers, storage, databases, networking, software) over the internet ('the cloud')."
Define IaaS.IaaS (Infrastructure as a Service) is a cloud computing service model that provides virtualized computing resources over the internet.
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 SaaS."SaaS (Software as a Service) is a cloud computing service model that delivers software applications over the internet, on a subscription basis."
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."
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 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.
Explain what DNS is.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.
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.
Define a VPN.A VPN (Virtual Private Network) is a service that encrypts your internet connection and hides your online activity from third parties.
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."
