… Q&A … cooool!

At this point im aware that a duplex mismatch is a speed error that doesnt seem to occur much in a modern environment however however the answers are something I’m still unsure of.

• Broadcast storms – A broadcast storm occurs when a network system is overwhelmed by continuous multicast or broadcast traffic.
• reduced performance – ok maybe i’m aware of this one
• packet collisions – When a packet collision occurs, the packets are either discarded or sent back to their originating stations and then retransmitted in a timed sequence to avoid further collision. Packet collisions can result in the loss of packet integrity or can impede the performance of a network.
• routing loops – A routing loop is a situation where a packet keeps getting routed between two or more routers because of problems in the routing table. In case of distance vector protocols, the fact that these protocols route by rumor and have a slow convergence time can cause routing loops.
• VLAN mismatch – Native VLAN mismatch and CDP. … The native vlan is used for untagged frames. So a frame without a tag on Switch A may be “viewed” as VLAN 1. If SwitchB has a native VLAN of 10, then all of a sudden traffic from one side of your network in VLAN 1 is being magically transferred into VLAN 10

uhaa, this doesnt make complete since but I sort of get the picture based on definitions. If traffic is set to be consumed slower at the destination than the source is sending it, I guess I could see how it could get stuck in a loop and have packet collisions. Obviously this is complete theory for me at this point as I have no idea how it really works.

This only sort of make sense and honestly it seems vendor dependant as why wouldn’t you use a console cable? There are several options. I’m not sure of what a loopback interface is though A loopback interface is a logical, virtual interface in a Cisco Router. A loopback interface is not a physical interface like Fast Ethernet interface or Gigabit Ethernet interface. … Loopback interfaces interfaces are always up and running and always available, even if other physical interfaces in the router are down. Thats helpful but im still not really sure what it does The loopback device is a special, virtual network interface that your computer uses to communicate with itself. It is used mainly for diagnostics and troubleshooting, and to connect to servers running on the local machine oh ok, its like that thing that assigns a link local address on your pc. I guess some how I didnt think of that definition.

I really dont know much about connectors or what these things are so lets make another list.

• RJ-45: These are like Ethernet connectors, 8 pin
• RJ-11: Phone cables
• ST: round fiber connector, connectors refer to having a “straight tip”, as the sides of the ceramic (which has a lower temperature coefficient of expansion than metal) tip are parallel—as opposed to the predecessor bi-conic connector which aligned as two nesting ice cream cones would. Other mnemonics include “Set and Twist”, “Stab and Twist”, and “Single Twist”,[citation needed] referring to how it is inserted (the cable is pushed into the receiver, and the outer barrel is twisted to lock it into place). Also they are known as “Square Top” due to the flat end face.
• SC: connectors, being square, have a mnemonic of “Square Connector”, which some people believe to be the correct name, rather than the more official “Subscriber Connector”.[6] Other terms often used for SC connectors are “Set and Click” or “Stab and Click”

Oh man, that’s easy once you know what it is. this test: list, list, lists. Hey remember when I put memes and commentary in posts because I had free time and found humor in stuff. Yeah me too. Here is a real obvious one, on the house.

Oh wait this is your first time reading this blog. Wow, don’t worry. your one of 4 people that has ever read this blog. (watch this) raise your hand if you’ve read this blog (one awkward guy in the back admits to it). I’m not sure this joke works but I think its funny to tell jokes to black holes…

I don’t know what a SOHO router is so I guess I should figure that out and then figure out what the stuff in the answers list is.

• SOHO router – A SOHO router is a broadband router built and marketed for small offices and home offices. … A SOHO network can be a mixed network of wired and wireless computers. and home offices.
• SPI – Serial Peripheral Interface (SPI) is an interface bus commonly used to send data between microcontrollers and small peripherals such as shift registers, sensors, and SD cards. It uses separate clock and data lines, along with a select line to choose the device you wish to talk to.
• Routing tables – ok maybe I know what this is but lets get a web def (lol) to be sure
• Switch port – literally a port on a switch, unless im reading this wrong. which is possible
• Port forwarding – (ok i know this one too, sort of) Port forwarding. In computer networking, port forwarding or port mapping is an application of network address translation (NAT) that redirects a communication request from one address and port number combination to another while the packets are traversing a network gateway, such as a router or firewall.

Why you would set up port forwarding is still a mystery, perhaps we should find out why you would do that. Update, this makes no sense and you should be able to login to a web interface for your cameras like every other security system. Have you ever seen shodan. Never mind. ok sure we have to set up port forwarding haha

This is slightly confusing and again, im not sure why wouldn’t use a console cable, which seems to be what A is describing. Regardless, lets get through some of this, absurd, but necessary injected jargon.

• Serial DB-9
• (this B answer, could they not have just said a regular ethernet cable?
• crossover cat5- this doesnt make a lot of sense, from what I know
• rj-11 on the rougher and an RJ-45, this is just weird.
• Rollover cable – Rollover cable (also known as a Yost cable, Cisco cable, or a Console cable) is a type of null-modem cable that is often used to connect a computer terminal to a router’s console port. This cable is typically flat (and has a light blue color) to help distinguish it from other types of network cabling. Ha! So a console cable…

I like these things where you learn stuff and the answer is obvious. I remember studying server for the first time and being like what in the ever loving shit is this and being able to find no information until I learned every aspect of server and then sort of was able to put together a vague concept of what the hell they where talking about. I should have gotten this done last night but at least I got it done this morning, so progress…yeah.
