Why Is Uploading Normally Slow

Most traffic flows from the Internet to you, broadband connections often have download speeds much faster than their upload capability. A typical "8 Meg" broadband connection would have an upload capability 20 times less than the advertised download speed, so more often than not - you are at the limit of your connection.

Remember that broadband speeds are measured in Megabits per second, and files are normally measured in Megabytes. There are 8 bits in a byte so you must divide your upload speed in Megabits by eight to derive the number of Megabytes you can upload each second.

Crucial Hard Drive Problems

The hard disk drive (HDD) is one of the most important and yet mysterious parts of a computer system. HDDs are sealed units used for nonvolatile data storage. Nonvolatile, or semi-permanent, storage means that the storage device retains the data even when no power is supplied to the computer. Because HDDs store crucial programming and data, the consequences of any failures are usually very serious. To maintain, service, and upgrade a PC system properly, it is important to know how hard disks function.

Hard disk drives contain rigid, disk-shaped platters, usually constructed of aluminum or glass. Unlike floppy disks, the platters can’t bend or flex—hence the term hard disk. In most drives you can’t remove the platters, which is why they are sometimes called fixed disk drives. Removable hard disk drives are also available.
