Topology
What is a star topology?
A network topology in which a cable runs from each computer to a single point.
What is Internet Protocol?
Set of rules for formatting and processing data
What is Internet Protocol?
Set of rules for formatting and processing data
What is binary?
*Hint* This is how computers communicate
Data is converted into this and then sent across the internet.
Explain the difference between a modem and a router.
A modem connects a network to the internet, while a router connects multiple devices to a network and manages traffic between them.
What is a ring topology?
A network topology in which a single cable runs continuously from computer to computer.
What is ISP or Internet Service Provider?
The organizations that provide internet
What is latency?
Time it takes for a bit to transfer from sender to receiver.
Used for wireless communication. Radio waves are a fundamental component of wireless networking, enabling data transmission over the air without the need for physical connectors.
What does LAN stand for?
Local Area Network
What is mesh topology?
A network topology in which each node connects directly to every other node on the network.
What is NAT? What does it do?
NAT, which stands for Network Address Translation, is a critical process used in networking. Its primary function is to translate private, internal IP addresses to a public IP address and vice versa.
What is a network?
Interconnected computing devices that can exchange data and share resources with each other.
Can a bit have a value other than 0 or 1?
No, a bit can only have a value of 0 or 1.
Name a common network operating system in Cisco.
Cisco's IOS (Internetwork Operating System). IOS
What is hybrid topology?
A mixture of network topologies such as ring and bus.
What is DNS or Domain Name System?
To visit a domain, how does your computer know the IP address of the server?
What is the Internet?
Global computer network consisting of interconnected networks. A network of networks.
How is data speed measured in a network?
Data speed in a network is usually measured in bits per second (bps).
Explain the difference between unicast, multicast, and broadcast.
Unicast is one-to-one communication, multicast is one-to-many communication, and broadcast is one-to-all communication within a network.
What is bus topology?
A network topology in which a single conductor connects to all the computers on the network.
What is the difference between IPv4 and IPv6?
IPv4 uses a 32-bit address format often requires manual configuration or DHCP and IPv6, with its 128-bit address format and supports auto-configuration uses hexadecimal notation
What is bandwidth? How is it measured by?
Max transmission capacity. Measured by bitrate.
Discuss the role of bits in encryption and security in networking
In encryption and security, bits are crucial for creating cryptographic keys, which are used to encrypt and decrypt data. The strength of encryption often depends on key size, measured in bits—the more bits, the stronger the encryption.
Explain the OSI model and its layers.
The OSI (Open Systems Interconnection) model is a conceptual framework used to understand network interactions. It has seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application. Each layer serves a specific function and communicates with the layers directly above and below it.
