Network Fundamentals
Every device on a `__` network is responsible for managing access to its own resources.
peer-to-peer
Wired LANs typically use _____ cables to connect devices.
Ethernet
A '___' is confined to a single geographical location.
local area network (LAN)
What layers are responsibility of the network?
Physical, Data Link, Network
Security device that controls incoming and outgoing network traffic
Firewall
In a '__' connection, two businesses or two locations within a network are connected to each other.
site-to-site
Satellite internet often suffers from _____ , the delay from a source to a destination.
latency
Connected devices sharing data (computers, protocols, transmission medium)
Network
Functions: Interacts directly with end-user’s software applications for network service
Examples: SMTP, DNS, FTP
Application
Malicious software designed to damage or disrupt a computer system
Malware
The world's largest public network; contains a vast amount of information
Internet
When creating a VPN connection, a user can choose the type of encrypted connection to use by configuring which option?
VPN type
Allows end users to have the freedom to use personal tools to access information and communicate using their:
Laptops
Netbooks
Tablets
Smartphones
E-readers
Bring Your Own Device (BYOD)
Name all 7 layers of the OSI Module in order
Physical, Data Link, Network, Transport, Session, Presentation, Application
Process of converting data into a code
Encryption
A transmission type in which a device transmits data to every other device on its network
Broadcast
enables computer within a home or remote office to connect to a corporate network
Small Office/Home Office(SOHO)
Three goals of network security
Confidentiality – only intended recipients can read the data
Integrity – assurance that the data has not be altered with during transmission
Availability – assurance of timely and reliable access to data for authorized users
Which protocol is faster but less reliable due to lack of error checking?
User Datagram Protocol (UDP)
Software that monitors and filters incoming and outgoing network traffic
Social Engineering
A device controlled remotely through a smartphone app or similar medium
Internet of Things (IoT)
'___' networks can deliver data, voice, and video over the same network infrastructure.
Converged
A network can expand quickly and easily to support new users and applications without impacting the performance of services to existing users.
Scalable
Explain the primary difference between TCP and UDP in terms of data transmission.
TCP is connection-oriented, meaning it ensures the reliable delivery of data with error checking and correction. UDP is connectionless, providing faster data transmission without guarantees of delivery
What is the primary function of the Domain Name System (DNS) in network communication?
DNS resolves a device's IP address based on its name.
