Network and Internet Flashcards
Talks about types of Networks and aspects of the Internet
A group of interconnected computers and devices that share resources and exchange data.
Network
A network that connects computers within a small geographic area (e.g., home, office, school).
Local Area Network (LAN)
A network that spans a large geographic area, such as the internet, connecting multiple LANs.
Wide Area Network (WAN)
A network covering a city or large campus, bridging multiple LANs over a region.
Metropolitan Area Network (MAN)
A small network that connects personal devices like smartphones, laptops, and Bluetooth accessories.
Personal Area Network (PAN)
A secure connection that encrypts internet traffic, masking the user’s IP address and protecting privacy.
Virtual Private Network (VPN)
A device that connects different networks and directs data between them, often linking LANs to the internet.
Router
A device that converts digital signals into analog signals (and vice versa) to connect a computer to the internet.
Modem
A networking device that connects multiple devices within a LAN and efficiently directs data to the correct recipient.
Switch
A basic networking device that transmits data to all connected devices without filtering, making it less efficient than a switch.
Hub
A device that amplifies and extends the range of network signals to reach distant devices.
Repeater
A device that provides wireless connectivity to a network, extending Wi-Fi coverage.
Access Point (AP)
A hardware component that enables a computer to connect to a network via wired (Ethernet) or wireless (Wi-Fi) connections.
Network Interface Card (NIC)
The most widely used IP addressing system, using a 32-bit address format (e.g., 192.168.1.1).
IPv4
A newer IP addressing system that uses 128-bit addresses, allowing for more unique IP addresses.
IPv6
A numerical value used to divide an IP address into a network and host portion, helping in network organization.
Subnet Mask
A unique hardware address assigned to a network device for identification on a LAN.
Media Access Control Address (MAC Address)
A network protocol that automatically assigns IP addresses to devices.
Dynamic Host Configuration Protocol (DHCP)
A web address that specifies the location of a resource on the internet.
Uniform Resource Locator (URL)
A protocol used to send emails between mail servers.
Simple Mail Transfer Protocol (SMTP)
A protocol used to retrieve emails from a mail server, typically deleting them after download.
Post Office Protocol version 3 (POP3
A protocol that allows email retrieval while keeping messages stored on the server, useful for accessing emails across multiple devices.
Internet Message Access Protocol (IMAP)
A protocol used to transfer files between computers over the internet.
File Transfer Protocol (FTP)
A secure version of FTP that encrypts file transfers using SSH (Secure Shell).
Secure File Transfer Protocol (SFTP)
A technology that allows wireless internet access using radio waves.
Wireless Fidelity (Wi-Fi)
A short-range wireless technology for connecting devices such as headphones, speakers, and smartphones.
Bluetooth
A short-range wireless technology used for contactless payments and data exchange (e.g., Apple Pay, Google Pay).
Near Field Communication (NFC)
A physical location or device that provides wireless internet access using Wi-Fi.
Hotspot
The latest mobile network technology, offering high-speed internet and low latency for mobile devices.
5G
