History of Computers and the Internet

Electronic computers were first developed in what decade?

• 1960s

• 1950s

• 1980s

• 1970s

DARPA's objective was to:

• explore the Internet in science labs around the world

• connect supercomputers are universities

• develop protocols

• see how they could connect together different packet networks

TCP/IP is:

• the government organization that started the DARPA contract

• the European Organization for Nuclear Research

• a set of rules governing the movement of data between devices

• an abbreviation for the World Wide Web

The World Wide Web is:

• a set of rules governing the movement of data between devices

• connect together different packet networks

• the ability to link hypertext documents in information systems and make them available from any node on the network

• national supercomputing centers at universities

The Internet began to carry commercial traffic in:

• 1995

• 1990

• 1986

• 1980

The Internet works by:

• moving your emails around the network in one big packet

• breaking the information you want to communicate into very small parts

• routing packets to avoid problems

• unique IP addresses

A packet can contain up to 1,500:

• IP addresses

• loads

• bytes

• emails

Which information does a packet NOT contain?

• where it came from

• what language it is in

• where it is going

• how many packets the email has been broken into

An IP address is:

• another word for packet

• a type of protocol

• composed of between 1,000 and 1,500 bytes

• a unique string of numbers that identifies a computer on a network

To ensure that all parts of your message arrives, the Internet uses:

• packet switching

• load balancing

• IP addresses

• return receipts
