    To what are you referring when you say "pcs"? Macs, tablets and Windows computers both in laptop and desktop formats can be designed for use by one person at a time. These are all personal computers (PCs). Compare these with computers that provide service to multiple users simultaneously. These are servers. To answer the question. It is quite likely that phones may become as powerful as modern PCs (both desktop and laptop). However, by the time the phones achieve that level of performance, top end laptops and desktops will have jumped further forward and probably by a substantial amount.

The phone line can also provide power for basic land-line telephone devices. More complex land-line devices require local power. Although broadband and baseband devices and telephone power can share the same phone line, the broadband and the baseband/power components have to be separated with the appropriate filters to prevent interference between the Internet and phone services. The 'phone line' may only have broadband services activated with no phone services. Similarly, the line may only have a phone service but no broadband. It is also possible that a fault in the phone line wiring it defeating the phone service signalling, while the broadband signalling is still functioning.

If System Restore is enabled, try rolling back to a restore point that was made before you hacked away important files. Alternatively, if you have created complete system backups, then simply restore the system from the last good backup. Unfortunately, many people do not bother with backups and lose everything when their hard drive fails.

Generally, your ping at less than 1 ms and you upload and download speeds both over 35 Mbps are very for domestic use. Your ping is exceptionally low. Although this is very unusual, it is excellent. It is rather unusual for the upload speed to be higher than the download speed. For most domestic ISPs the upload speed is often between 5% and 25% of the download speed. For business connections a symmetric speed connection is more common.

    It sounds as though your Internet is working properly, but your WiFi is the problem. WiFi, like Ethernet, is just an interface between the router and your devices. Ethernet cables between the router and each device are dedicated connections. WiFi is a shared interface used by all devices using the WiFi network. WiFi also shares the wireless frequencies with other nearby networks and heavy traffic on a neighbour's network using the same or a near adjacent channel will cause serious interference to your connection. However, some devices simply have compatibility issues with certain WiFi networks, which can me no connection, slow connection or a connection that drops randomly. Ditch WiFi and try Ethernet. If that works then its a WiFi issue and that is your responsibility and nothing to do with the ISP.

  • Should the page file be on C drive or can it be on D drive?

    Best answer: The operating system uses the Logical Block Address (LBA) to define which block of data it is reading or writing. With an HDD, the lower LBA values address tracks on the disk closer to the outer edge of the disk. These tracks are longer as their circumference is larger, and with a nominally uniform bits/cm, the data rates are higher at these lower value LBAs. This makes these outer tracks work faster for two reasons. The first is that the amount of data transferred in a revolution of the disk is higher. The second is that with more data per track a file system on these outer tracks, it requires fewer tracks for a given size file system, thereby requiring fewer and shorter time wasting head movements. With an SSD, which has no moving parts, access to the whole storage area works at the same speed. Moving the page file from C: to D: on the same SSD makes no difference to speed. (Moving to a separate SSD from C: can provide a speed improvement, but the question suggests there is only one SSD.) As far as wearing of the SSD is concerned, the LBA provided by the operating system is mapped to a physical address within the SSD's storage array. The SSD has no knowledge of partitions, logical disk drives (C: and D:) or the file systems in the SSD. Wear levelling aims to keep the number of write cycles fairly constant across the whole SSD. The mapping of LBA to physical addresses is adjusted so as to even out the write wear across the whole SSD. When a block is rewritten to a file by the operating system, the actual write will normally go to a different part of the SSD from that where that logical block was previously stored. In the scenarios of the question, the only reason for moving the page file from C: to D: would be to make more space available in C:. With 30 GB free in C:, this should not be necessary in your system. I hope this helps.

    WiFi in the BR player simply means it can connect to a WiFi network.Remember, WiFi does not necessarily mean Internet. You can have a WiFi network with no Internet, or you can have an Internet service connection with no WiFi. For most households with a router, WiFi provides a connection to the router, and the router provides a connection to the Internet service. Depending on the BR player, its WiFi may allow you to stream Internet streaming services through your router, and then feed the video to your TV over whatever cable type the player uses. Alternatively, the WiFi may allow you to stream films from the player to devices such as a tablet, laptop or a WiFi connected TV. You will need some form of Internet connection. A device, such as a wireless router, to convert the Internet connection to WiFi, and for some of the video streaming services you have to pay to use the service. Some TV catchup services and YouTube and similar services can be free. You will have to pay for a legal Internet connection unless you have a benevolent neighbour. If your phone is a smart phone, you might be able to turn on its WiFi hotspot and connect the player to that WiFi to use the cellular Internet connection. I hope this helps.

    Have you actually thought about what you are asking? The switch is in position 'b' then switched to position 'a'. Which in on and which is off? Are the R and C in series or in parallel? Where is the switch in relation to Vb and R and C? For example, if R and C are in series, and the switch applies power to the RC duo in position 'b', then Vc will remain at 2.65V when the switch moves to 'a' disconnecting the applied voltage as there is no path to discharge C. Alternatively if R and C are in parallel, and and 'b' is off and 'a' is on. When the switch moves to 'a' C will immediately receive 2.65V subject to any impedance in the voltage source. Now try asking the question in a way that is unambiguous and includes all the relevant information.

    I have never seen a manufacturer claim such a ridiculous figure as 2 million hours. However, 5 years seems rather short. I have had many drives still performing properly after 8 to 10 years. Slow performance can be down to many things: Disk fragmentation (HDDs require defragmentation, while SSDs should never be defragmented) A build up of a large number of junk files on the drive. Microsoft's Disk Clean-up and/or Piriform's Ccleaner should help clean up some of the junk. Keeping everything on C:. The outer part of a disk drive is faster than the inner areas. Keeping the operating system in C: near the outer edge of the disk and putting all private data on a separate logical drive D: possibly on the same physical drive can be more efficient. Upgrades in antivirus software may be imposing a bigger load. Before you go too much further, use Task Manager (and Resource Monitor if it exists in Windows 7) to see where the bottlenecks are occurring and what processes may be causing the bottlenecks. I hope this helps.

    Various other answers point out that many establishments off "free WiFi". It is free for their customers. Legally you need to buy something to entitle you to use the WiFi. A purchase gives you implied permission to use the network during that visit. If you connect to a network without permission then, depending on your local laws, you may be guilty of hacking and/or theft. If you simply want free WiFi, find someone who is disposing of an old wireless router that still works. Provide it with power and configure it to your requirements and you will have almost free WiFi. I assume you still have to pay for the small amount power the router will consume. I also assume that what you really want is Internet access and not just free WiFi. WiFi and Internet access are two different things. Sorry, I will not give you advice on how to steal Internet access.
