What model divides the network communication process into seven layers?
Open Systems Interconnection (OSI) model is the one which divides network communication process in to seven layers....
"ifconfig" is a command found in most *NIX operating systems (think UNIX, Linux, BSD, etc...). it's equivalent in Windows is "ipconfig". it is a command you call from the shell (not the graphical user interface) that allows you see/set IP configurations for a specific interface.
The number chosen for the uTorrent port is not that important (other than avoiding the ports commonly blocked by ISPs: 6881-6999).
What is important is clearing that port (forwarding) through any firewall, software or hardware (router) on your system. A firewall will block uTorrent communications (as it should) unless an exception is made to allow uTorrent.
This guide had information to help with that:
Optimizing µTorrent for Speed

Because you isp have slow download speed and fast upload speed.
What is the purpose of network?
A lot of young people (13-16 year olds) like having facebooks to be able to chat with their friends. People in their early adults (20ish) like having them to stay in touch with friends from college, high school, etc. In my opinion, people in their 30s and 40s should only have fbs. This is to stay in touch with old friends who are now spread out around the world. I strongly advise against fb unless you are in your 20s-40s because its unneccesary for teens to have fbs and then get in trouble for stupid posts and dumb comments. Plus, watch out. If you are applying for a job, your boss and collegues WILL check you out online. If they find something bad or inappropriate about you online (ex. on facebook) they WILL NOT hire you. Facebook is only good, in my opinion, for adults and I find it completely unneccesary for teens to have fbs. Unfortunately, most of my friends have fbs.

What protocols to use on networks?
That depends on the type of network you are talking about. For instance, the Internet is a network and uses TCP/IP as its protocol. Intranets based on Microsoft Server also use TCP/IP. However, there are other protocols.
Why a lan user can not monitor the internet?
The simple answer is that a LAN user (client) will not see all of the packets on the Internet; they will only see the packets for their own LAN segment.
What is TRACERT and when might you use it?
It is a basically a means of use to find out all the ip addresses you came across. That is a s basic as i can describe it. It is short for trace route. Unless someone has disabled cookies on there computer you wont find there ip, also, emails and such. Also depends if yours is enabled or not either. It is a big raise on security concerns. Hackers used this process when the BBS systems were still around. YOu can use it to find out collectively who's ip is what, and where. Sometimes the computer you are using it on will only show you limited viewing, you will have to understand command prompt a bit more to further venture in the details. More i cannot say, but this is the internet and age of wide information use it delicately.
Hope this helps
Which protocol is implicitly denied at the end of an IPv4 access list?
Standard ACLs filter IP packets at the source address only. Extended ACLs filter IP packets based on other protocols including; source and destination IP addresses, source and destination TCP and UDP ports and protocol types (IP, ICMP, UDP, TCP & Protocol No). The protocol that is implicitly denied due to filtration is HTTP.
physical layer.
Yes. You need to have an IP (either static or dynamic) You must have a subnet mask that corresponds to the IP address; and a gateway IP address that is on the same subnet.
If you are referring to a modem, the it is a device that allows your computer to connect to the internet.
What kinds of available systems sufficiently secure the reliability of network transmission?
TCP does, not sure about others. TCP can handle out-of-order packets and lost packets. Even though TCP does some rudimentary error checking, corrupted packets sometimes get through.
How do I change mac address of my Aztech dsl605ew DSL Modem?
You can't. The MAC address is a permanant part of the device.
Does SNMP act as a complete solution to network monitoring?
It's the backbone of network monitoring, but it's not the only thing that can or should be used. Microsoft for example does not recommend using SNMP for OS monitoring on security grounds. The more advanced monitoring software out there like NetCrunch 8 will use performance data from the OS itself, instead of relying on SNMP. Flow data like from NetFlow can also give you much deeper insight into your network traffic than SNMP can. Most simpler devices will rely on SNMP however, like your IP phones, printers, etc.
What purpose does a WAN link provides?
WAN means Wide Area Network, in which computers are connected beyond areas. Main use of this network is for data communication across computers.
E.g., E-Seva service connectors in andhra pradesh are connected through WAN, it is easy to transfer information from one branch to another
What are the features of wnhanced interrior gateway routing protocol eigrp?
It is a Hybrid routing protocol.
It provides configurable metrics.
It establishes formal neighbor relationships among routers.
Which network devices can be found in LAN but not with WAN?
An LAN card is a must if you wish to connect to a LAN but it is not required for WAN
