| What is a 'Node' ? | A point of connection on a network |
| What does 'ISP' stand for? | Internet Service Provider |
| The standard protocols for receiving email? | Pop3 (old version), iMap Server |
| What does 'DNS' stand for? | Domain Name System |
| What does 'FTP' stand for? | File Transfer Protocol |
| In studio 1, what cable connects the C24 to the Mac Pro? | Ethernet |
| When a client communicates with another client on a network, it is called? | Peer to Peer Relationship |
| When a client connects to a server it is called? | Client to Service Relationship |
| What is 'Star Topology' ? | It is a network configuration where nodes are added in a modular fashion to the 'Central Device' |
| In a Star Topology Network set up, what happens if a 'computer' dies? | Nothing. The network is un-affected |
| What happens if the 'control device' dies on a Star Topology Network set up? | The entire network goes down |
| What does 'NIC' stand for? | Network Interface Controller? |
| Another phrase used to describe a 'Network Interface Controller' ? | Network Adapter |
| Each adapter has 2 things that it uses to connect to the network? | 1. Unique MAC (Media Access Control) Address 2. User defined IP Address |
| What is a MAC Address? | 12 digit handwired hex address (00.08.96.CC.DA:68) |
| Note about Ethernet & Wi-Fi? | Regulate low level data transmission in LANs Ethernet = CAT5 / Fiber Wi-Fi = Radio Signals |
| Switching refers to? | Using a device to direct network traffic between nodes |
| What is an Access Point? | Operates as a wireless hub, broadcasting incoming signal to all wireless nodes |
| What does a 'Repeater' do? | Used to prevent signal deterioration and extend signal distance |
| What is a 'Router' ? | A device typically used to connect nodes/computers/LANs to the internet |
| What does a 'Modem' do? | Converts LAN traffic into a signal suitable for transmission to and from IPS |
| What is 'Data Compression' ? | Reducing file size by reducing # of bit required |
| Why do we Compress Data? | It reduces requires for Storage & Transition |
| What is 'Codec' ? | An algorithm used to compress/dcompress digital data |
| What is 'Wrapper' ? | Wrapper is essentially the file format for data compression |
| In regards to Data Compression, what is 'Lossless' ? | A decoded file which is bit for bit identical to the original file |
| In regards to Data Compression, what is 'Lossy' ? | Data discarded during compression |
| What are some types that can be 'Lossy' ? | Audio, Images, Video |
| What are some types that can't be 'Lossy' ? | Program files, Database files |
| For audio compression, what are some Lossless Formats? | FLAC, Apple Lossless, Dolby TrueHD |
| For audio compression, what are some Lossy Formats? | MP3, ACC, OGG Vorbis |
| What is Perceptual Coding? | Analyzes audio based on psychoacoustic mode to determine frequency content that is either below the thershold of human hearing or masked by other freqs |
| What is Bitrate? | Data rate on a compressed file |
| What is CBR? | Constant Bit Rate - Each second is same bit rate |
| What is VBR? | Analyzes complexity of audio and decides how many bits pers second it needs |
| What are the 2 video codecs that are guaranteed to work with protools? | Apple ProRes 422 HQ Apple ProRes 422 Proxy |
| The video codec that is not guaranteed to work with protools? | H.264 |
| What does NAS stand for? | Network Attached Storage (basically a file server) |
| What does NIC stand for? | Network Interface Card |
| What are some general requirements for network communication? | Means to identify individual nodes/hosts A medium for data transmission Routing devices Protocols to regulate transmission |
| What is a Low Level Protocol? | IEEE 802 Standard that focuses on LAN networking |
| What is a Circuit Switched Network? | A dedicated circuit created between two points |
| What is a Packet Switched Network? | Data is split into packets, stamped with destination addrss and routed there (LANs & WANs) |
| What is TCP / IP ? | It is a mid level protocol |
| What does TCP stand for? | Transmission Control Protocol - Manages data transfer between nodes |
| What does IP stand for? | Internet Protocol - Addresses packets |
| Things to note about IPv4 | 4 byte address written in decimal that must be unique in its network |
| In IP addresses you refer to a byte as an | An Octet |
| What does UDP stand for? | User datagram protocol |
| Notes about UDP | Less overhead and no error correction When near 'real-time' transmission is desired |
| Is IP Address Space limited? | Yes |
| What does NAT stand for? | Network Address Translation |
| What does NAT do? | Stretches IPv4 address space by allowing single internet IP address for all hosts on a LAN |
| What is PING? | A program that tests TCP/IP connectivity |
| What are some High Level Protocols? | HTTP, DNS, DHCP, VoIP |
| LAN IP Addresses digit allocation | First 7 digits indicates host Last 3 indicates host |
| What is a Subnet Mask? | Used to reveal network & host portions of IP addresses |
