2.4, 2.5, 2.7, 2.8 (80 cards)
Internet Service Provider (ISP)
a company or organization that provides individuals, businesses, and other entities with access to the Internet
- Connection Types: Fiber Optic, Cable, DSL, Satellite, Cellular
- Technologies vary in throughput speed, price, and availability
Fiber Optic
- wired
- Fastest
- Expensive
- Less available in rural areas
Cable
- wired
- fast
- uses cable television infrastructure
- moderate cost
- moderate coverage area
Cellular
- wireless
- uses cell tower
- expensive
- moderate coverage area
Volatile Storage
a type of storage that requires a continuous power supply to retain data random access memory RAM
- power is cut off or system is turned off the data storage is lost
- making it temporary
Non-volatile Storage
a type of storage that retains data even when power is lost or the system is turned off
- hard disk drives, solid-state drives, optical disks, and flash drives
Local Device Storage
Local device storage encompasses hardware components used to store data on a computer device locally, as opposed to remotely or on another device
- RAM
- Hard Disk Drives (HDD)
- Solid State Drives (SSD)
- Optical Drives
- Flash Drives
Network
two or more computing devices linked together by some form of transmission medium that enables them to share information
- The Mail Delivery System
- Telephone System
- Social Networking
- The Internet
Computer data network
is a collection of hosts connected by networking devices such as computers, printers and smart devices
Local Network Storage
refers to the various types of storage systems that are accessible over a local area network connection, allowing multiple devices to share and access stored data
- File Servers
- Network Attached Storage (NAS)
Cloud Storage
refers to the practice of storing and managing data on remote servers accessed over the internet. It involves using the infrastructure of a cloud service provider, which maintains large-scale data centers to store and protect the data of individuals and organizations
Hard Disk Drive (HDD)
a type of local device storage where digital data is stored magnetically on a spinning disk
- low cost
- Moving parts increase failure rate
- Slower than solid state drive (SDD)
Solid State Drive (SSD)
a type of local device storage where digital data is stored on non-volatile flash memory chips
- faster than hard disk drive (HDD)
- no moving parts
- silent operation
Optical Drive
a type of local device storage where digital data is stored optically on a spinning disk
- compact disc (CD)
- Digital Versatile Discs (DVD)
- Blu-Ray Disc (BD)
Flash Drive
a type of portable storage device where digital data is stored on non-volatile flash memory chips
- same storage technology as an SSD
- Local device storage designed to be portable
File Server
a type of local network storage in which a general computing device provides centralized storage and file-sharing capabilities to multiple users on a network
Network Attached Storage (NAS)
a type of local network storage in which a dedicated computing device provides centralized storage and file-sharing capabilities to multiple users on a network
Cloud Storage
the practice of storing and managing data on remote servers accessed over the internet
Read
retrieving information from a storage device, and bringing it into the computer’s system memory for processing
Write
storing our updating information on a storage device, allowing you to modify existing data or add new data
Protocol
refers to a set of rules and standards that govern the exchange of information between devices or system
- defines how data is transmitted, received, interpreted and acted upon during communication
- without this communication across networks would be chaotic and prone to errors
Local Area Network (LAN)
a wired network that covers a small geographical area, typically within a building, small office or home
Wide Area Network (WAN)
a network that spans a large geographical area typically connecting multiple LANs or remote locations this is used to connect networks across cities, countries, or even continents
- enable long-distance communications and data exchange
- Wireless Wide Area Network (WWAN)
Network Packets
are like small envelopes that carry chunks of data across a computer network when you send or receive information over a LAN or WAN network it’s divided into smaller pieces called packet
