Computer Networking
Computer networks are collections of computers which are connected together in order to communicate and transfer information. Questions about computer networks, networking protocols, and how to set them up belong here.

When would optical fiber be used in ethernet lan?
When you need to cover distances longer than 200 meters. Also fiber optics is recommended when you have high load connection, for instance, between building, floors and so on.
The question I need answered is if Obama says I didn't start my business myself and had help then why did he not help to stop failure. The government never helped me and as far a roads and bridges that's why we pay taxes. We the people paid for all of the roads and bridges with our tax dollars. I also don't understand why we should not need ID to vote. Last time I looked you need an ID to drive an ID to buy liquor and an ID to fly but voting you don't need an ID. Make the people get an ID. Trust if these people they couldn't get on the plane with out one. This looks like voter fraud. How about a birth certificate. Just because you like Obama as a man you must look at his record. In business I have fired people that I really liked because they could not perform their job. Is Obama doing his job. Talk about off shore or business off shore? Five of Obama's staff have business off shore and accounts off shore. Obama clean your house before you as us to make sacrifices. Another GDP that 1.5% its bad bad news.
dB = 10log10(50Watt)
= 10log10(1000/50)
= 10log10(20)
= 1 + .3010
= 1.3010dB
1.3 - 10 = -8.7dB
What does Artillery ammunition means?
heavy weapon Ammunition fired in artillery weapons such as cannons, howitzers and mortars.
Are capital expenses required for managed network services?
Not necessarily, but they can be a key element in many business solutions. It all depends, complex communications can be a responsibility that eats up budget, time and human resources.
What is an autonomous system and what routing protocols operate within an autonomous system?
An autonomous system is a group of networks under the same management domain using an interior gateway protocol such as OSPF.
Internetworking with Cisco and Microsoft Technologies pg. 308
Interior gateway protocols: IGRP, RIP, OSPF, EIGRP
Internetworking with Cisco and Microsoft Technologies pg.295-296
Where can I find a process control network?
You can find a process control network located at any large or small company that uses a base computer system. It is basically an ethernet system. It allows the company to have a connected system that communicates with each other.
Can you see Animation of OSI seven layer model?
i want to see a complete animation of osi seven layer model
How do you converion baud rate to symbol rate?
baud rate = symbol rate= modulation rate
all the same thing
Decisions on which port to block when two ports have equal cost depend on the port priority and identity.
Non-root switches each have only one root port.
Token Ring is a network protocol used for local area networks (LANs) that employs a token-passing method to manage access to the shared network medium. The primary purpose of Token Ring is to prevent data collisions by allowing only the device holding the token to transmit data, ensuring orderly communication. This protocol was developed by IBM and was popular in the 1980s and 1990s, though it has largely been supplanted by Ethernet technology in modern networks.
What is a full-class C in CIDR notation?
Under CIDR, the subnet mask notation is reduced to a simplified shorthand. Instead of spelling out the bits of the subnet mask, it is simply listed as the number,
the network address would be written simply as: 192.60.128.0/22
which indicates starting address of the network, and number of 1s bits (22) in the network portion of the address. If you look at the subnet mask in binary (11111111.11111111.11111100.00000000), you can easily see how this notation works.
The use of a CIDR notated address is the same as for a Classful address. Classful addresses can easily be written in CIDR notation (Class A = /8, Class B = /16, and Class C = /24)

What is the geographical scope of LAN MAN and WAN?
Local area network, Metor area network, Wide area network
STP has two common meanings in networking:
1. Shielded twisted pair, a type of cable.
2. Spanning-tree protocol, a system used to permit redundant links in switches, while avoiding switching loops.

BGP (Border Gateway Protocol) is classified as an Exterior Gateway Protocol (EGP). It is used to exchange routing information between different autonomous systems on the internet, which distinguishes it from Interior Gateway Protocols (IGPs) that operate within a single autonomous system. BGP is essential for determining the best paths for data to travel across the complex structure of the internet.
