It is important to test the cables before you install them and after they are installed. Although there are many tools that are used for testing the cables in a network this paper is only going to talk about three. The first one is the multifunction cable scanner, they are available for testing both copper and fiber optic cable. One such model is the Hobbes 258898 it can test every pin of almost 20 often used cables from coax to 40 pin ribbon cables. It identifies opens, shorts and mis-wires at the pin level. With a multifunction cable tester you can perform a range of tests that you would normally need a few different testers to do. You can do wire-mapping, test for the length of the cable, test the attenuation, and you can test NEXT (near end crosstalk) for copper cables. They will also test for optical power and signal loss in fiber optic cables. A lot of the multifunction cable testers perform other more comprehensive test such as PS-NEXT, ACRF, PS-ACRF, delay…
The problematic scenario is when the physical sequence has a loop. In this scenario, a switch which is attached to the middlebox literally cannot identify the middlebox segment based on the combination of the input interface and packet header fields. To address this scenario, SIMPLE introduce a ProcState tag that encodes the packet’s processing state inside the packet header fields using either VLAN tags, unused fields in the IP headers i.e., IP ToS fields or MPLS labels depending on the fields supported in the SDN-enabled switches. Therefore, SDN controller installs tag addition forwarding rules at the first switch of each middlebox segment, which is based on packet header fields and input ports of the switch. In addition, downstream switches consider these tags for the matching purpose and perform respective forwarding action. This process continues until the middlebox segment is finished.…
A good example of refraction of light and reflection of light is a rainbow. Sunlight enters the rain droplet at a specific angle and the rain droplet separates the white light into many different colors. This angle is a fixed measurement between your eye and the sun. What color is refracted depends upon the critical angle, which is the angle the sunlight strikes the back of the rain droplet. Red light bends the least while violet light bends the most all the other colors bend at an angle that is between the two. Each rain droplet reflects all colors at a given point and time, but only one color comes back to your eye, requiring millions of rain droplets to create a rainbow. As the rain droplets fall…

I recently had to deal with a problem with the Event Name as: BlueScreen. The Locale ID of the fault can be designated by the numerical value as: 5146. I am a touch apprehensive as to whether such a typical fault has been triggered owing to a virus attack. What should I do to eliminate the fault and ensure that the problem does not occur all over again?…

Analysis and explanation of the threat and vulnerability pairs and their likelihood of occurrence. The chart explains the aspects of the vulnerabilities and threats. b\Because we have no data on these threats on the amount of occurrences we cannot assign an impact rating or a probability rating in which is high medium an low (reference page 121 of book)…
NTFS is the newer filing system from Windows only Windows 2000 and higher use NTFS and FAT32. Which file system is intended primarily for use in large USB flash drives? I think it would be NTSF it a little more better an newer when it comes to the new OS out there like windows 8/7/ and maybe Vista XP just in case you have application that might run better on vista and XP. Plus since USB didn’t come out until Windows 98 well that when I first saw a USB port…
