What are the essentials of networking?

Planned Sequence of Topics and/or Learning Activities

  • Standards and the OSI and TCP/IP Models.
  • Addressing.
  • Transmission and Media.
  • Topologies.
  • Connectivity Devices.
  • WANs (Wide Area Networks) and Remote Connectivity.
  • Routing and Switching.
  • Wireless network.

Which two devices are considered end devices?

Some examples of end devices are:

  • computers (workstations, laptops, file servers, and web servers)
  • nsetwork printers.
  • VoIP phones.
  • TelePresence endpoints.
  • security cameras.

What is the effect of setting the security mode to WEP on a small wireless router?

Setting up WEP, WPA or WPA2 wireless security

  1. Ensure that no one can easily connect to your wireless network and use the Internet without any permission.
  2. Personalize access on who can configure your wireless settings.
  3. Protect all data that is transmitted through the wireless network.

What three pieces of information are identified by a URL?

URLs typically consist of three pieces:

  • The name of the protocol used to transfer the resource over the Web.
  • The name of the machine hosting the resource.
  • The name of the resource itself, given as a path.

What is the difference between network advantage and network essentials?

Cisco DNA Essentials delivers base automation, monitoring, and management. Cisco DNA Advantage delivers policy-based automation with SD Access, monitoring, and Cisco DNA Assurance. Customers need to buy ISE Base, ISE Plus, and Stealthwatch® to enable all Cisco DNA use cases.

What layer is a hub?

Layer 1
The key difference between hubs, switches and bridges is that hubs operate at Layer 1 of the OSI model, while bridges and switches work with MAC addresses at Layer 2. Hubs broadcast incoming traffic on all ports, whereas bridges and switches only route traffic towards their addressed destinations.

What are two common media used in networks?

Common media used in networks include copper, glass or plastic optical fiber, and wireless.

What is WPA2 used for?

WPA2 is a type of encryption used to secure the vast majority of Wi-Fi networks. A WPA2 network provides unique encryption keys for each wireless client that connects to it.

What does HTTP stand for?

Hypertext Transfer Protocol
Hypertext Transfer Protocol/Full name

What are protocols?

In networking, a protocol is a set of rules for formatting and processing data. Network protocols are like a common language for computers. The computers within a network may use vastly different software and hardware; however, the use of protocols enables them to communicate with each other regardless.

What are the two major networks?

There are two principle kinds of networks: Wide Area Networks (WANs) and Local Area Networks (LANs).

What addresses are added at the physical layer of a network?

Logical addresses, also known as IP addresses, are added at the network layer. Physical addresses are edded at the data link layer. Port addresses are added at the transport layer. No addresses are added at the physical layer. What are two benefits of using a layered network model?

What happens if the host does not have a default gateway?

The host can communicate with other hosts on remote networks, but is unable to communicate with hosts on the local network. There is no impact on communications. A default gateway is only required to communicate with devices on another network. The absence of a default gateway does not affect connectivity between devices on the same local network.

Which layer of the network device does a network administrator install?

A network administrator installs a network device that focuses on interconnecting independent local networks. At which layer of devices does this technology reside? The distribution layer connects local networks and controls the traffic flowing between them.

What are the common types of media used in networks?

Common media used in networks include copper, glass or plastic optical fiber, and wireless. What is an advantage of using standards to develop and implement protocols? A particular protocol can only be implemented by one manufacturer.
