How does DNS improve the name resolution?
The clear advantage of DNS is that it makes it easy for us to remember the names of websites by converting or displaying the IP addresses(that are in numbers) in understandable names.
Which companies use packet switched wan?
Packet switching is the most common form of data transportation. Unfortunately, there is no list of companies that employ WANs, so this question really cannot be answered.
GET VPN is a new category of VPN developed by Cisco, one that does not use tunnels. By eliminating point-to-point tunnels, Cisco Group Encrypted Transport VPNs can scale higher while accommodating multicast applications and instantaneous branch-to-branch transactions.
Can you connect computer and printer by switch?
Yes, you if you printer has network interface (NIC). u can connect them through routers or switch
The reason most used refusals by an employer is probably because personal computers might contain viruses and other nasty surprises.
Is the Network 172.32.0.0 a part of the private address space?
No, that address space ends at 172.31.255.255
How do you identify the presence of a network ready printer?
Just check behind or on the right side of the printer where there will be a square hole. If your network cable fits in it, a GRAND SUCESS!
It uses the Bellman-Ford algorithm to determine the best path.
It displays an actual map of the network topology.
It offers rapid convergence in large networks.
It periodically sends complete routing tables to all connected devices.
It is beneficial in complex and hierarchically designed networks.
What are the principles of data compression?
There are some basic principles of data compression. They include advantages, disadvantages, and the history of compression. Types of compression include BZip2 and LZMA.
Virtual Router Redundancy Protocol (VRRP) enables you to set up a group of routers as a default gateway router (VRRP Group) for backup or redundancy purposes. This way, the PC clients can actually point to the IP address of the VRRP virtual router as their default gateway. If one of the master routers in the group goes down, one of the other routers can take over.
Routers can function as master or backup routers, and you can actually configure up to 255 virtual routers on a router interface. Of course, there are platform constraints like router memory, for instance. Additionally, VRRP is intended for use with IPv4 routers only.
How do you upgrade wep security to wpa2?
You have to have a router capable of supporting WPA2 as well as a wireless adapter in your computer should support it too. If you are sure that you satisfy both, you need to log in your router, and in settings for wireless network security choose WPA2.
What connects other computers through telephone or cable televison lines?
A modem. However, there is a card that can connect computers trough telephone or cable television lines, too.
A clicking sound on a HDD is always a bad sign. Connecting an ethernet cable should not make any difference to the hard drive. In my opinion you should back up all your data and get a new hard drive. The days left in your hard drive are counted!
UDP
What are these networks that connect LANs in geographically?
If they are in a local geographic area but two separate networks that would technically be a WAN. Of course some people call them MAN's for "Metropolitan area network."
im not really sure however it is called LAN for local area network. try asking that.
A set of computers connected in one classroom is an example of?
it depends on the circumstances, if there is a server in the room and a switch/router then they will be using the mesh star but if not and all the computers have 2 Ethernet ports on the back of them then they are more than likely to be using the Ring topology.
But these days they are normally connected to switch ----> Then a Router -----> then a Server which is connected to the internet and has a very strong and secure firewall.
^^^^ IGNORE !
Local area network. :)
Try disabling your proxy server. Most of the time, you don't NEED a proxy server.If you do need one, you may need to consult with your ISP, about the specific setting you need for your proxy server.
What are the benefits of cable sleeving?
The main benefit of cable sleeving is the protection that the sleeving provides the cables. Sleeves may be made of, for example, nylon, fiber and stanless steel. A company that sells cable sleeving is Cable Ties and More.
What is a service provided by the Flow Label field of the IPv6 header?
This 20-bit field provides a special service for real-time applications. It can be used to inform routers and switches to maintain the same path for the packet flow so that packets are not reordered.
