What device is used to send data between two networks?
If the message is going between two different networks then it must be routed (this includes different subnets of the same network as well). Routing is done by a router as the device.
What is the scope in computer hardware networking?
It varies from computer to computer.. It's sometimes infrared and sometimes iron sight.
Usually the systems will be assigned an APIPA address in the range 169.254.x.y in order to use resources in their own LAN.
The APIPA configuration can also default to static IP addresses if necessary.
If APIPA is not being used then the only way to use the network is to manually assign a static IP address and all of the required settings.
What network topologies are most commonly used on today's networks?
star topology. Because they include a centralized connection point; can easily be moved, isolated, or interconnected with other networks; they are, therefore, scalable. For this reason, and because of their fault tolerance, the star topology has become the most popular layout used in contemporary LANs.

What is the difference between osi and iso model?
ISO stands for International standards organization.It is an organization for agreement on international standards of network communication world wide.
On the other hand OSI is a model for understanding and designing a network architecture.
You can enable MAC address (also know as Physical Address) filtering. MAC address filtering has two modes:
1. Allow access to listed MAC addresses
2. Deny access to listed MAC addresses.
When can a domain local group be converted to a universal group?
Always, because it has no restrictions
when the domain functional level is
•Windows 2000 native or Windows Server 2003:
You can convert universal groups to domain local groups or to global groups
What is the difference between WiFi and wireles mesh networks?
A wireless mesh network really doesn't make sense; the mesh topology assumes that every node in the network has a connection to every other node, and is primarily used for fault tolerance.
With wireless technology there is no concept of a "connection", therefore having a mesh topology with a wireless network would be very difficult.
Wi-Fi is a wireless technology.
Can people get internet from fiber optic cables?
Verizon FiOS & Verizon Broadband Services offer blazing speed & crystal clarity of the 100% fiber optic Fios network & proven reliability for their TV, Internet & phone products that will exceed your expectations today & keep you connected down the road

What are the purposes of switches and hubs?
Switches increase the number of collision domains in the network.
What are the ways to configure DNS Zones?
If using Windows, start the DNS snap in via administrative tools and right-click Forward Lookup Zones to create a new zone. A wizard will start impromptu you for the information needed. Additionally, an Active Directory integrated DNS server can be made by creating a DNS server, starting the DNS manager, and changing the zone type to be Active Directory stored.
Which two layers of the OSI model have the same functions as the TCP model network layer?
physical & data link layers
What port number is used to HTTP?
The Standard Port & Default is Port 443. You may however configure secure HTTP on another port through some software such as Servers (Apache, IIS, Xampp,etc)
Which of the following is an example of asset management on a client server network?
The question is incomplete. There are no options given (for "which of the following") to answer this question.
Which two layers of the OSI model do NICs belong?
Primarily in the Physical (first) layer to be the transciever for the Line, but many cards
these days also have acceleration and cache MAC-IP addresses and and speed up
ARP requests and translation to IP Addresses which are at the Link (second) Level.
Which is the network id for an ip address of 172.17.67.85 using the default subnet mask?
ip addresses from 172.16.0.0 thru 172.31.255.255 are private and do not route on the internet.
What is the subnet mask for ip address 5.5.65.12?
Smaller than 65.56.0.0/14. With just the IP, there is no way to know the netmask. We can see that Level 3 owns that address and their block is a /14.
It could be a /30 with a gateway of 65.56.25.18.
it could be a /29 with a gateway of 65.56.25.18-22.
In short, there is no way to definitively know the netmask from the IP only.
What network technologies does not use circuit switching?
Packet Switching - Computer Communications (Digital)
Circuit Switching was used for old fashioned telephony. At present, many companies use VOIP (Packet Switching) for voice communications.
Name 2 networking devices that transmit packets based on MAC address?
A MAC address is used as a unique identifier that is assigned to network interfaces. Two networking devices that transmit packets based on MAC addresses are switches and bridges.
Can a workstation computer be configured to browse the Internet and yet NOT have a default gateway?
If we are using public ip address, we can browse the internet. If it is having an intranet address a gateway is needed as a router or firewall to communicate with internet.
***********************************************
Without default gateway you cannot browse internet. It doesnt matter if you are on public or private network. Default Gateway is required to route your IP packets from your network to the other networks.The Data Link Layer of OSI reference model provides the service of error detection and control to higher layers. It accomplishes this task by having the sender break input data into data frames and transmit sequentially and process acknowledgement frames.
It have two sub layers:-
1. Logical Link Control sublayer
2. Media Access Control sublayer
