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.

What could cause packet loss at the router?
There are a number of reasons for packet loss; bad cabling, bad ports, too many collisions on the network, attenuation in the cable, bad routes, etc.
That sounds like a firewall.

Do network adapters enable nodes in a network to communicate with each other?
Essentially, the answer is yes - what is required is a proper implementation of a network stack on each node (which will allow the user application to actually utilize the network adapter for communication), as well as a working physical connection between the two nodes abiding to standards. In these terms, an example of a
most simple network based on Ethernet would be two PCs each equipped with a Fast Ethernet network adapter with installed drivers for their respective operating system, connected by a CAT5e 100BASE-TX UTP crossover cable.
What do you understand by''logical search''?
A logical search is by its own name a simple definition. It means when doing a search for information start with the first logical steps, for example if you are researching different types of rocks you are not going to start your search by searching for trees.
What connects one Autonomous System to another Autonomous System?
the answer to this would be an edge router
Why does IPv6 use separate extension headers instead of fields in a single fixed header?
IPv6 includes an improved option mechanism over IPv4. IPv6 options are placed
in separate extension headers that are located between the IPv6 header and the
transport-layer header in a packet. Most IPv6 extension headers are not examined or processed by any router along a packet's delivery path until it arrives at its final
destination. This facilitates a major improvement in router performance for packets
containing options
Why are protocols important to LANs and WANs?
just like, for smooth flow of vehicles, there is need of some rules and regulation.
same is application in case of internet or lan and wan
otherwise collission, loss data packets will happen
The MAC address is unique to each device, assigned by the manufacturer, and cannot be changed. Thus making it an excellent security device.
Doing this for 700 pieces of equipment would be quite time consuming.
User name and corresponding password for windows system. You have to have an account with enough rights to be able to connect to windows through network.
What type of cable is used in most star networks physical medium?
Rj-45 is the most common type of cabling. RJ-45 refers to the terminator (connector) on the end of the cable, and the jack it plugs into--more specifically RJ-45M and RJ-45F, respectively. The associated cabling will be CAT(category)-5 or CAT-5e(enhanced), which are in the class of Unshielded Twisted Pair. A star network is typified by the hub or switch, with a cable running from it to every device on the network. Other cabling might be used, but CAT-5 is far and away most common.
What is the Difference between hardware and networking?
Hardware are the parts of a computer or system of computers. Hardware includes things like DVD drives, memory modules, graphics cards, and power supplies. Networking is the term used for a connection of multiple computers. The majority of businesses have a network so that the information can be accesses from any of their computers.
Describe at least five key principles in the design of layered network architecture?
Principles are not advantages or disadvantages of the layered approach, principles are behind the layered approach
Principles:
- Data transmission error free.
- Minimum time for route discovery.
- Communication between layers through primitives.
- Congestion control for minimum delays and retransmission.
- Minimum effort in replacing new layer in the existing network layers.
Briefly describe the benefits of monitoring when making network systems secure?
Monitoring will alert you to potential problems that may lead to downtime, or when it comes to security, they can alert you when suspicious activity is occurring on your network.
What do you mean by the source code page viewed in a web browser?
what do you mean by the "source code" page viewed in a web browser
P E R T is the acronym for Product Evaluation Review Technique. C P M signifies Critical Path Method.
Definition of Router in computer networking?
In networking there is a source and a destination and when both of them communicates there is transfer of packets. There are many routes that can be taken to deliever packet from source to destination but out of all the routes the best route is to be selected, which is done by router and this process is called as routing.
How to connect internet one computer to another computer in windows-xp environment?
Basically, one computer is used as a "bridge" for the other computer. So in the Network Connections, you have a wizard to create a new connection. If the other PC is connected direclty with a modem, then your other computer will have access to internet via this other comp.
You might be interested in so called wireless extenders, they do exactly what you need. ---- I assume you are referring to increasing the range of a router? My problem is there is no way to get internet access in a nursing home, except through the use of of a wireless connection through AT&T, Sprint, so some other service, people use when away from any WiFi link. It's slow, but better than nothing. Would like to add a router so that others can access it, so that we can split the cost. At $40 a month, plus taxes, that takes nearly 100% of the monthly allowance the nursing home is required to give us out of our SS checks, regardless of how much those checks are. Most of us already owned a laptop at the time we came here. In my case, I was a cab driver until I got sick from CO2 poisoning over a year ago. The money we get has to cover any personal expenses, such as a telephone, shampoo, clothing, etc.
a. All switch and bridge ports are in the forwarding state. b. All lkswitch and bridge ports are in the stand by state. c. All switch and bridge parts are assigned as either root or designed. d. All switch and bridge ports are in either the forwarding or blocking state. e. All switch and bridge are either blocking or looping.
