Networking

• Networks support the way we work by enabling remote access to work files and facilitating teamwork.
• Networks support the way we play by providing access to entertainment and enabling social interaction.
• Hardware without a single point of failure is a measure to ensure availability in data networks.
• Data networking involves the transmission of information over a network, and there are many factors that can prevent a message from reaching the recipient or distort its intended meaning.
• Quality of service in network architecture is a characteristic that guarantees a certain level of service for specific types of traffic.
• All networks have four basic elements in common: devices, medium, messages, and rules.
• Some data network symbols include a device, medium, message, and rule.
• Network architecture design addresses fault tolerance, scalability, quality of service, and security.
• Network architecture technologies support the infrastructure, programmed services, and protocols that move the messages across that infrastructure.
• Fault tolerance in network architecture is a characteristic that ensures the network continues to function even if some components fail.
• Network connections are a crucial aspect of data networking.
• Security in network architecture is a characteristic that protects the network from unauthorized access, modification, or destruction.
• Scalability in network architecture is a characteristic that allows the network to accommodate increased traffic without disruption.
• Transmission Control Protocol/Internet Protocol (TCP/IP) is an industry standard in networking today and the primary protocol of the Internet today.
• Converged networks are a type of network that can carry voice, video & data over the same network.
• Four common basic element of the INTERNET are: Device, Medium, Message, Rules
• What is Medium?


  This is how devices are connected together.
• Transmission Control Protocol/Internet Protocol(TCP/IP) is?

  Is a set of a standard rules that allows computers to communicate on the network such as internet.
• Converge Network are:

  Converge Network are:
• Converge Network are:


  A type of network that carry voice, video data over the same network.
• network architecture


  Technologies that support infrastructure, th e program service, and protocol.
• Characteristic address by network architecture design:

  Fault Tolerance, Scalability, Quality of Service, Security.
• Network outage


  This prevent the communication and transactions occuring, with consequent loss of business.
• Misdirection and loss


  Some data or things can be loss without proper security.
• 3 common elements pf communication:

  Massage source, the channel. message destination.
• What is "Segments" ?


  this is the data sent across the network in a "small chunk"
• Local Area Network (LAN) :


  A network serving a home, building or campus.
• Wide Area Network (WAN)


  LANs seperated by geographic distance are connected by WANs.
• What is Internet?

  a global mesh of interconnected network.
• What is protocol?

  This is a set of rules used to facilite communication over data network.
• TCP/IP Model is?

  first layer protocol model for internet protocol.
• TCP/IP Model comprises four layers such as:

  Application. Transport, Internet, Network Access.
• In four layer of TCP/IP, what is Application?

  Application is represents data to the user plus enconding and dialog control.
• In four layer of TCP/IP Model, what is Transport?

  Transport is support communication between diverse device and diverse network.
• In four layer of TCP/IP Model?

  Internet, d4etermine the best part through the internet.
• In four layer of TCP/IP model, what is Network Access?

  Controls the hardware devices and media that make up the network.
• Protocol data units and encapsulation:

  DATA>SEGMENT>PACKET>FRAME>BITS
• What is a Open Sytem Interconnected Model or OSI Model?

  OSI model is used to described the function of a network system.
• What is the 7 layers of the OSI Model?

  7.Application>6.Presentation>5. Session>4. Trasport>3. Network>2. Data Link>1. Physical.
• what is the 7th layer of OSI Layer model and its definition?

  Application means end to end connectivity between individuals.
