Binary Numbers

The ancient Indian mathematician Pingala presented the first known description of a binary numeral system in the 3rd century BC.

In November of 1937, George Stibitz, then working at Bell Labs, completed a relay-based computer he dubbed the "Model K" (for "Kitchen", where he had assembled it), which calculated using binary addition. Bell Labs thus authorized a full research program in late 1938 with Stibitz at the helm. Their Complex Number Computer, completed January 8, 1940, was able to calculate complex numbers. In a demonstration to the American Mathematical Society conference at Dartmouth College on September 11, 1940, Stibitz was able to send the Complex Number Calculator remote commands over telephone lines by a teletype. It was the first computing machine ever used remotely over a phone line. Some participants of the conference who witnessed the demonstration were John Von Neumann, John Mauchly, and Norbert Wiener, who wrote about it in his memoirs.

1. What is a packet?
Parts of the information sent

2. What is a configuration table?
A configuration table is a collection of information

3. What are the two jobs of a router?
The router ensures that information doesn't go where it's not needed. This is crucial for keeping large volumes of data from clogging the connections of "innocent bystanders."
The router makes sure that information does make it to the intended destination.

4. Under “Transmitting Packets” what different routes (e.g. copper wiring) may information take?

5. The largest routers used to handle data at the major traffic points on the Internet are most like _________ rather than office routers.

6. Routing Packets: What is a subnet mask?
The subnet mask looks like an IP address and usually reads "255.255.255.0." This tells the router that all messages with the sender and receiver having an address sharing the first three groups of numbers are on the same network, and shouldn't be sent out to another network.

7. What is a logical address?
describes a way someone can get a message to you
8. What is a MAC Address?
Media Access Control

Computers in School

1) I use computers in 1st period for Html but outside that only in 2nd period.
2)I would allow more access but not too much everything to make students and teachers confortable using the computers.
3)Computers are a good investment but not these computers _{they stink}
