IT Vocab 7 Flashcards
A network device that connects wireless devices to a wired network
Access Point
A protocol that combines HTTP with the Secure Sockets Layer (SSL) protocol to securely transfer web content between computers
Hypertext Transfer Protocol Secure (HTTPS)
A technology used to create wireless connections between computers and devices
Bluetooth
An important protocol in the internet protocol suite that is generally used when speed in transmission is more important than accuracy since the sending computer doesn’t verify that the packets were correctly recieved
User Datagram Protocol (UDP)
A protocol used to receive email; is deleted from a server after it is downloaded to a client
Post Office Protocol 3 (POP3)
A protocol that governs the transfer of web content between computers
Hypertext transfer protocol (HTTP)
A technology that uses cable TV lines to establish high-speed connectivity to the internet through an ISP
Cable
A network device that moves traffic between two different IP networks
Router
A small network device with modem, firewall, routing, and switching features that is used in homes and small businesses
Home Router
A technology that uses specially encoded tags that respond in a specific way when scanned by a radio frequency reader. NFC is often used by placing a smartphone near a scanner to pay for an item in a store
Near Field Communications (NFC)
A technology that used fiber optic cables that carry light signals to establish high-speed connectivity to the internet through an ISP
Fiber Optic
The principal communications protocol in the internet protocol suite that is used to route information over the internet
Internet Protocol (IP)
An important protocol in the internet protocol suite that enables two hosts to establish a connection and exchange data
Transmission control protocol (TCP)
A class designation (A through E) that specifies a default subnet mask value which defines the default network address portion of the IP address
Default Address Class
A technology that uses phone lines to establish high-speed connectivity to the internet through an ISP
Digital Subscriber Line (DSL)
A technology that sends signals to and from a satellite to establish connectivity to the internet through an ISP
Satellite
Short for modulator/demodulator, a network device that converts digital signals used by modern networks to analog signals that are typically carried by telephone or cable TV lines
Modem
A network device that moves traffic within an IP network
Switch
A technology that uses radio signals to connect a device to an access point
Wi-Fi
A protocol used to send email
Simple Mail Transfer Protocol (SMTP)
The unique, burned-into read-only memory address of a network interface. This is also called the media access control address or MAC address. MAC addresses are burned into the read-only memory of every single network interface, such as wireless network adapters and network interface cards. This makes it virtually impossible to change the device’s MAC address
Physical Address
A network security device that protects a network by examining the traffic before transferring it to the network
Firewall
A technology used in the early days of the internet where a computer would make a phone call to the ISP to establish internet connectivity
Dial-Up
An address assigned by software and, as such, can be changed. it includes two parts, the network address and the host address. The most common types are those assigned by the IP protocol and are called IP addresses
Logical Address
A protocol that helps internet users and network devices discover other devices using a human-readable hostname instead of numeric IP addresses
Domain Name System (DNS)
A technology that uses cellular radio signals to establish connectivity to the internet through an ISP
Cellular
