- Q:Hi, I have a router connected to the internet, but one of the computer is 80 feets away from the router and it can not get 100MBps. I have force the computer to use 10MBps. Could someone please let me know what will impact the speed of cat5 cabling?
- Ok, please note the following: MB/s = MegaBYTES per second Mb/s = MegaBITS per second 10MB/s = 100Mb/s (roughly) Your router and NIC card is 100Mb/s (unless they are both Gigabit - Gb/s which will give you roughly 100MB/s in speed assuming both the NIC and router can support that speed.) I hope this answers your question.
- Q:I was just wondering because I need a new power supply for my computer. It is an Acer Aspire AM3910-U4012. Is the power cable that connects to the motherboard the only power cable I need to replace or will I need to replace all the cables in my computer for it to work properly?
- If your current power supply is modular and you buy the same brand of modular power supply to replace it, then you can use most of the existing cables, if you want to. For most power supplies, all the cables are permanently attached. But there's nothing wrong with using existing cabling if it is modular. You have to be aware that different brands of power supplies use different types of modular cables, though. If you change brands of power supply, most likely you will need to replace all power cables, regardless of if they are modular or not...
- Q:So I'm trying to add a sata hard drive from an older computer in my new one, but I encountered a problem. I have the cable the connects to the motherboard and the hard drive, but when looking at the power connectors for the hard drives, there is only one and it is connected to the main hard drive. Am I missing something that is slapping me in the face here, or is this a design flaw? there are 6 hard drive holders sooooo, it seems that there should be 6 power cords inside, but no. Only one. What do I do?
- Your chasis ia able to hold 6 hard disk but seems like your power supply does not. You can buy a cable splitter for the power or buy a new power supply. Do take note of the wattage rating on your power supply. Since there is only 1 cable, it may not have enough wattage to support the hardware
- Q:hi, i just got a new graphics card for my PC and it needs a 6 pin power cable so i got one but i don't know where to plug it in (not on the graphics card but in the computer) can some one help me pleas.
- follow your power supply unit (PSU) main loom and try to find one that is the same on the video card if there is not one you should have at least one of those 4 pin ones it is usally white or black about 5mm thick and 25mm wide you can get adaptor plugs I had to get some for my new video card just goto to a decent computer store and they will have them I paid about $4 for each and they had 2X6pin from the one adaptor plug
- Q:I'm trying to plan out my new install and I'm debating whether or not to spend money on power cable adapters and run o gauge to a distribution block thats 0g in and 4g out, therefore running a 0 to 4g cable adapter inbetween every terminal on the distribution block --or-- to Instead run 0 to the distribution block and 4 from the block to everything. I have a 1200RMS sub amp and a 200RMS 4-Channel amp. Hi output alternator. Big 3. So if anyone can give me some advice on whether or not they're worth the money that would be awesome. Oh and my amps accept 4 gauge.
- back interior the day while audio electronics grew to become into evolving from monophonic sound to stereophonic sound, manufacturers of stereo audio electronics unique the left channel enter for monophonic sound (in case you purely had one enter) and, if there grew to become into no longer something plugged into the final enter jack, the monophonic sound grew to become into dispensed to the two left and precise inputs. on the grounds that mono is fantastically uncommon at present, i don't be attentive to if this remains accepted on stereo inputs (alongside with powered subwoofers), yet you're able to attempt it. If it relatively is no longer the case (plugging it into the left enter purely is going interior the direction of the left amplifier), no remember in case you chop up the sign or no longer is in fact a wash. A subwoofer has 2 voice coils on the motive force, one powered by making use of the left enter and the different powered by making use of the final enter. in case you purely have, say, the left enter plugged in, you're purely using the subwoofer with the left amplifier and voice coil. in case you chop up it, you're actually using the two voice coils. yet, the chop up itself cuts the sign point in 0.5. So, you have 0.5 as plenty sign enter to each amplifier and the output quantity of the subwoofer is not any diverse than purely plugging in one enter. one factor you need to do is to get a small, affordable stereo amp or receiver, plug the LFE output into one enter, set the amplifier mode to mono, and run the two line outputs to the subwoofer. that should offer you 2 finished line point inputs to the subwoofer from the single LFE cable.

- while you're meaning are you able to boot off of the IDE annoying force and get entry to the Sata force, the respond is sure. in basic terms connect the SATA annoying force, and make beneficial the BIOS settings are set to boot from the IDE force.
- Q:There have been severe storms in my country Kenya and power lines have fallen and caused a lot of injuries, some fatal to pedestrians, motorists and others.I am sure if power lines were covered with rubber sheathing or some other apopropriatde material, there would be less likelihood of electrocution, serious injury, fire or property damage. I am a lay person in these matters so I am talking from what I have seen.Thanks in advance.
- Let's see... First of all ONLY high voltage power cables do not have protective polymer insulation. Low voltage cables, like the ones that bring outlet tension to homes do have an insulation, usually made of PVC, rubber, silicone and such. The large, 10000Volts, up to and over 200000 volts and so on do not for several reasons: 1. It would be impractical to make. For usual materials, like PVC the thickness of the insulation would be extreme (I think as thick as several centimeters) as to protect from such high voltages. Such insulations would make the cables break under their own weight. 2. The cables heat up really good under the enormous currents and voltages so the insulation plastic would be close to melting point all the time. 3. PVC is quite senzitive to weather curing. It becomes brittle and cracks if left under weather condition for several years so the insulation would still serve to no good. Furthermore, regulations regarding aerial wiring state that they should avoid crossing populated areas, roads, etc. unless absolutely necessary. Also, wires fallen on ground should definitely not be messed with. Furthermore, if high voltage cables were insulated, this would only serve ready made combustion materials for fires in case of short circuits and damages. I guess this takes care of your question...
