day 4 question...

1. What are Internet cookies?
Cookies provide capabilities that make the Web much easier to navigate. The designers of almost every major site use them because they provide a better user experience and make it much easier to gather accurate information about the site's visitors.

2. What are packets?
It turns out that everything you do on the Internet involves packets. For example, every Web page that you receive comes as a series of packets, and every e-mail you send leaves as a series of packets. Networks that ship data around in small packets are called packet switched networks. A typical packet contains perhaps 1,000 or 1,500 bytes.

3. What route do packets take over the Internet?
Each packet is then sent off to its destination by the best available route -- a route that might be taken by all the other packets in the message or by none of the other packets in the message. This makes the network more efficient. First, the network can balance the load across various pieces of equipment on a millisecond-by-millisecond basis. Second, if there is a problem with one piece of equipment in the network while a message is being transferred, packets can be routed around the problem, ensuring the delivery of the entire message.

4. What is a 404 error on the web?
The 404 or Not Found error message is an HTTP standard responce code indicating that the client was able to communicate with the server, but either the server could not find what was requested, or it was configured not to fulfill the request and not reveal the reason why. 404 errors should not be confused with "server not found" or similar errors, in which a connection to the destination server cannot be made at all.

5. What is 'e-commerce'?
Electronic Commerce is exactly analogous to a marketplace on the Internet. Electronic Commerce consists primarily of the distributing, buying, selling, marketing and servicing of products or services over electronic systems such as the Internet and other computer networks.

6. What is the difference between ebay and craigslist?
Craigslist is categorized by different areas while you don't know where the products are coming from on ebay.

7. What is SSL?
Short for Secure Sockets Layer, a protocall developed by Netscape for transmitting private documents via the Internet. SSL uses a cryptograph system that uses two keys to encryp data − a public key known to everyone and a private or secret key known only to the recipient of the message.

8. What are the two major ways for home users to connect to the Internet via a high speed connection?
DSL and Broadband.

9. What is a T-1 line?
T1 line, it means that the phone company has brought a fiber optic line. A T1 line can carry 24 digitized voice channels, or it can carry data at a rate of 1.544 megabits per second. If the T1 line is being used for telephone conversations, it plugs into the office's phone system. If it is carrying data it plugs into the network's router.
A T1 line can carry about 192,000 bytes per second -- roughly 60 times more data than a normal residential modem. It is also extremely reliable -- much more reliable than an analog modem. Depending on what they are doing, a T1 line can generally handle quite a few people.
