Crash Course Computer Science

2. although many LAN technologies were developed and deployed the most famous and successful was what developed in the early 1970's at Zerox PARC
3. every computer connected to a network gets a what
5. with millions of computers online exchanging data what can appear and disappear in milliseconds
7. network routers are constantly trying to balance the load across whatever routes they know to ensure speedy and reliable delivery, which is called what
9. whats interesting about these bigger networks is that there's often multiple paths to get data from one location to another and this brings us to another fundamental networking topic
13. the number of hops a message takes along its route is called the what
15. in its simplest form, a what are connected to a single, common Ethernet cable
16. Ethernet requires that each computer has a unique media access control address or what
17. another approach for getting data from one place to another is what

1. a second benefit of networks was the ability to what
4. it also had the nice property of being what with no central authority or single point of failure
6. to reduce collisions and improve efficiency, we need to shrink the number of devices on any given shared carrier, what's called the what
8. this is essentially how big computer networks are constructed, including the biggest on of all
10. the solution is to chop up big transmission into many small pieces called what
11. as network traffic increases, the probability that two computers will attempt to write data at the same time also increases, this is called what
12. this what if all the computers use the same wait duration so a random period is added
13. the internet what in leaps and bounds in the decades since
14. many computers can simultaneous sense the carrier, hence the sense in multiple access and the rate at which the carrier and transmit data is called its what
