are: - Answer-Added
,The TCP/IP protocol suite that is widely used today corresponds to a model that
contains how many layers? - Answer-5
The primary motivation for early computer networks was email due to computers being
large and expensive. - Answer-False
The Advanced Research Projects Agency, an agency of the US. Department of
Defense, gathered researchers and contractors together to produce a working data
network known as? - Answer-ARPANET

- Increase in communication speeds
Multimedia is Data that contains a combination of ? - Answer-- text
- video
- graphics
- audio
Recent trends in computer networks and the Internet include: - Answer-- cloud
computing
- social networking applications
- traditional communications systems adopting Internet technology
- high-quality teleconferencing
- sensor networks
Which of the following statements describe a connection-oriented interaction? -
Answer-- A pair of applications requests a connection

- A computer dedicated to running one or more server programs
- A program that waits passively for communication
, Can a computer operate multiple clients and even multiple copies of a single
application? - Answer-Yes
Can a computer run multiple server programs? - Answer-Yes
Can consolidating multiple server programs on a single computer reduce cost without
significantly reducing performance? - Answer-Yes
How does a client identify a server on the Internet?
A. Internet Protocol address
B. Protocol port number - Answer-A. Computer
B. Service
When a request arrives at a server, software on the server uses the IP address to
determine which application on the server computer should handle the request. -
Answer-False
A server can act as a client. - Answer-True
If only one server provides a given service, the network connection that connects the
server to the Internet can become a bottleneck. - Answer-True
