how do you remove yellow triangle on my network connection icon ?

if you have a yellow triangle that means there is something wrong with your motem. i reccomend just restarting it. if that doesn't work it may be whoever you are buying the internet from (at&t, comcast, ect.)

what is difference between kw and kva ?

kw is the unit of real power & kva is the unit of apparent power.

apparent power= real power + reactive power

besides this,the ratings which we write on a motor or generator is kva & not kw. b'coz there are two types of losses in a motor or generator- core losses & ohmic losses. core loss depends upon the voltage applied & ohmic losses depend upon the current flowing & none of these losses depend upon the power factor i.e. [email protected] as we know that

kw power = v * i *[email protected]

but as the losses are independent of the power factor hence we need to calculate only kva = v*i.

comment

apparent power is the vector sum of real power and reactive power, not the sum.
kva is the unit of apparent power and kw is unit of active power.

kw is kilowatts, and kva is kilovoltamps. kw is the apparent power that a normal power meter would measure, while kva is simply the maximum of the instantaneous product of volts and amps divided by 1000. the difference between these two terms is due to phase angle, which is due to the reactance of the load to an ac power source.

kw (kilowatts) is apparant power, while kva (kilovoltamps) is true power. they are different when the phase angle between voltage and current is not zero, i.e. when the load is reactive, such as in a motor. the ratio of kw over kva is power factor, and is the cosine of the phase angle between voltage and current. it is zero at a phase angle of 90 degree, which occurs for purely (ideal) inductive or capacitive loads with no resistance in the source or conductors, and it is one for purely resistive loads.

what are the benefits of fiber optic broadband ?

fiber is just better all around offers more speed than normal wired internet compared to fiber and verizon offers the best in that department+ big deals right now on their website here

how much does broadband service cost per month and what does it include ?

broadband service can cost anywhere from $15.00 to $300.00 per month.

for typical home use, it runs between $15.00 - $50.00.

there are many different flavors of 'broadband', cable, which comes through your television cable, and you have dsl, which has many flavors, depending on how close, or far, you are from the phone company's central office. basically, the further you are away, the more expensive it will be. some are not expensive but some are. try at&t yahoo high speed. it is only $14.00 or $12.00.

if you have broadband should you leave your computer on all the time ?

it honestly is up to you. it is actually better to leave it on as you retain your connection to the isp and in most cases, don't have to renegotiate your download speed (which could get a bit slower the next time you connect).

other information

it depends... you should be definitely be protected with a hardware or software firewall, whether your computer's on all the time or not. you're vulnerable even during short periods of use, as a broadband connection is "always on."

you can test your vulnerability at grc.com. or go to www.grc.com and look for the link to "shields up." there's also a lot of valuable info here about security and vulnerability if you want to wade through it (at www.grc.com).

i have a small network and my router acts as a hardware firewall. a good software firewall is zonealarm. one version is a free download at zonelabs i left mine on all the time, and despite the fact that i had xp and zonelabs, i got hacked and have been through 4 drives since. i need a new computer as once they " get your number" -- you're history.

my hack was a high level corporate entity -- so like the other guy said w basic firewalls you are ok for the most part. me? i'm so paranoid now i unplug the phone line when i'm not using the machine! when you are not using your computer tune it or off disconnect from the internet (for safety). if you have a ะฝะพัƒั‚ you should never just keep then on for a long amount of time, they tend to burn out due to heat. if you have a desktop then it you chose but save some money from the power bill and turn it off. firewalls are a must when you are online.

heat and system wear are likely a more important issue here. if you choose to leave a desktop running 24/7, make sure it is in a cool, dust free area. also, listen closely to the fans running. if they get louder or higher in pitch, its probably time to turn it off and use a can of air to blow the dust out.

here's how to dust it out

1. shut down the pc, then unplug it

2. remove a side panel. (most have a release latch or a couple of philips head screws along the back of the case)

3. get a can of air, and blow all the dust out

this will keep your desktop healthy and allow you to run it constantly. you may want to restart it at least once a day. windows tends to become unstable if not allowed to restart, and some vital updates and programs will not apply without a restart.

concerning viruses, you should always have an antivirus installed on your pc. if you are broke, i recommend avg free edition, and spybot s&d for anti-spyware.

(if you have a laptop, abandon the idea of leaving it on all day. they are not designed to dissipate heat quickly enough, and most likely it will fail within six months of such treatment. )

---

no, you shouldn't as if you turn your computer off it is off so it can not be hacked because while it is off it doesn't exist unless someone has used a virus which is very rare that when you turn of your computer it stays off but here is a little advice make sure you have an up to date anti -virus, spyware etc and scan your computer now and then for viruses and you should be fine also don't allow others to connect through your printer or something like that because then you will get hacked and if you see a file on your desktop you don't recognize scan it because it may be a trojan

i have been using broadband for the past 8 years and rarely do i turn off my computer. i have not been hacked or gotten any viruses. if your system has anti-virus, anti-spyware and is firewalled up you will have no problems keeping your computer on and connected to the internet. unless of course you are downloading from a p2p which may leave a port or two open and then you might get hacked.

how can you get rid of a virus in a broadband connection that changes username and phonebook entry of a dialup connection every time you reboot ?

sorry folks to bother you, but i found the solution myself! here's how it goes: the entire process may take anything between 30 mins to an hour and a hlaf depending on pc speed and amount of data stored.

download the following softwares: 1. ad-aware se personal 2. about:buster 3. hijackthis

all of the above mentioned softwares are freewares.

once you have downloaded these, update their definition files very simple, each of these contain a update button just click and it updates itself. also update your anti-virus software

now, restart your system in safe mode (press f8 at start up)

scan your system for viruses - use your anti-virus to do this (if it asks for a restart, do so, but restart your system in safe mode again) once you're done with that, scan your system with the ad-aware se utility. select all "critical objects" and quarantine them.

now run a scan using the about:buster utility, it will automatically fix the errors, it will ask for a scan for a second time, do so.

finally run the hijackthis utility. be very careful while using this it could cause irrepairable damage to your system. results would typically look something like: o3 - toolbar: norton antivirus - {the registry key} - c:\program files\norton antivirus\navshext.dll o4 - hkcu\..\run: [yahoo! pager] c:\program files\yahoo!\messenger\ypager.exe -quiet

select the suspicious files.. ones that aren't a part of the windows os, and click on the fix checked button

that's it! just restart your system, this time in normal mode. this should solve your problem.

what was introduced to make ipv4 internet routing more efficient ?

internet protocol version 4 (ipv4) routing has not changed in nature, its facilities for routing traffic are as simple as a table of subnets with their respective gateways and a relative weight or priority for each, also a default gateway. routers are connected to multiple networks, and they choose the best route for each ip packet based on the packet's destination ip address.

if any efficiencies in ipv4 routing have been developed, they have probably either been in proprietary router logic, or the development of additional communication protocols established to allow routers to communicate with each other, allowing each participating router to expand the horizon of its own network map. once able to see 2 or 3 hops away, rather than just 1 hop as is the capacity of a local ipv4 routing table, and additionally, track the relative latency for each of those interconnects, a router might actually be able to make a more intelligent decision about which remote gateway is best to use for each particular packet.

for example, border gateway protocol (bgp), enhanced interior gateway routing protocol (eigrp), routing in place (rip), etc. some of these protocols may be implemented on top of the ip layer, but probably not always the case.

efficiencies in routing can be gained whenever a router has more than one path to the same destination. delivering a packet of ip data is just like taking a road trip, or an airplane flight, or routing a phone call. similar to routing a fedex deliver truck through 50 stops in a day. there is a real cost to the bandwidth required to transfer the data, or more the truck, so the most efficient would ideally be the least expensive, but not always so. the primary factors that one may want to make more efficient are probably: speed, latency, $cost. what is efficient is a relative term.

internet routing and the efficiencies to be gained fall under classification of np-complete and are in fact one of the few types of questions that our computers just cant answer in any significant degree of timelines. common example is the traveling salesman problem.

this topic could probably also be included in net neutrality issues. most commonly the net neutrality debate is focused around type of content, but it could just as well be centered around the interconnectivity of different provider networks, and difference is transfer rates between those networks. sounds a lot like the phone system in that each country has its own phone network and each interconnect has a different rate. of course, with with internet telephony most of those phone calls are probably routed over ipv4 networks anyway.

should cities offer free public wi fi ?

no, they should not.

because it would cost money that could be contributing to cleaner parks and safer streets.

why is the maximum speed of a modem limited to 56kbps ?

it really depends on your line quality. the bandwidth of a typical copper line maxes out 56kbps. but it's never guaranteed to reach that speed due to line quality, noise and etc. the modems are all able to connect to each other by following established standards. the standard set for dial-up modems has a maximum data transfer rate of 56 kilobits per second. the government limits the power level of the signal, so it actually is less than 56k. your line quality (distance from the central office (co), line loading coils, environtmental factors, branches off of the main line, etc., all affect the bandwidth that can be transmitted across the lines. the modems will negotiate the fastest speed that they can, depending upon their settings, line quality, and supported protocol (k56flex, v.90, v.92, etc.) dsl modems use frequencies above the normal bandwidth of dial-up analog modems. dsl modems are capable of speeds up to a few gigabits per second. because of the higher bandwidth of dsl, line loading coils and other factors may prevent its use. many telephone companies have been extending their optical fiber networks out to the neighborhoods, reducing the distance between your home and their equipment. this has made dsl possible in many more areas where it was not possible before. because of the higher frequencies used by dsl equipment, filters are required for regular analog phone equipment. the filters are put between your telephone, answering machine, or modem and the telephone line. the dsl modem connects directly, without a filter.
