IPv4 c What name do we use for the format Dotted decimal notation d Who uses this format—humans or computers? Humans e Convert the following bit binary IP address into DDN spaces are added for easier reading : In the first printing, this was erroneously printed as IPv4 h What other type of IP address exists, and how long is its addresses? The Internet is not a single network. It is a collection of single networks and smaller internets. No one.
Users will not tolerate delay or unreliability b What is transcoding? Changing a movie or other video into a form that can be delivered to consumers by Netflix or another streaming services. To serve the particular needs of specific user equipment and network conditions.
For transcoding, selecting the best transcoded version for a particular user and set of network conditions, and personalized recommendations.
They place a local content server near the user. Virtualization and Agility 6. Physical servers are real computers.
Business Data Networks and Security 10th Edition by Panko
Virtual machines are parts of a server that act like computers but are not. A physical server may have many virtual machines. VMs can be quickly spun up, spun down, or moved to different physical servers.
Nearly instantaneous setup, tear-down, and movement to another machine. Creating a new VM. It spins up additional VMs during peak viewing time and tears them down in low viewing periods. Do not just spell out the acronym.
A cloud service provider that provides a service opaquely so that customers do not have to worry about the details. IaaSs provide VMs with operating systems but no application software. SaaSs provide VMs complete with specific application software. The cloud server provider in SaaS; the customer in IaaS. It does not manage the servers except in the sense of creating, deleting, or moving them. It does manage the applications. Clients Move into the Cloud 8. All data files, applications, and application program personalizations are available to them.
Virtual clients can share files with other virtual clients easily. It avoids large one-time expenses in buying software and replaces it with smaller monthly expenses to pay for the service.

At least some of the management work is outsourced to the CSP. Rain Clouds: Security 9. What concerns do customers have about cloud security? That critical corporate data in the cloud may be hacked, that the government may be secretly looking at their data Networks and the Cloud Describe the relationship between cloud computing and networking. The explosive growth of cloud computing is putting a strain on network capacity.
It must pay a penalty c Is network speed usually measured in bytes per second Bps or bits per second bps? In other words, how many bits per second is it? Some applications, such as e-mail, do not need fast connection speeds to be effective. Others, such as video streaming and data backup, do. Speed to individuals is what individual employees experience. Corporate network speeds must be high enough for the aggregate speeds of individual employees.
It is written properly. Dividing an application message into many smaller parts that will each be sent in a packet or frame. They are small messages that carry application message segments. They travel across an internet packet or a single network frame. Having the packets or frames of multiple users share a physical transmission line.
Individual users do not have to pay for an entire line; they only pay for the capacity they actually use. What are the three defining characteristics of single networks? A single networks uses a single technology for transmission.
There is a controlled address space such that each host address is unique, like a telephone number. Messages in single networks are called frames, not packets. Single-Network Host Addresses EUI b What else is it called? There are only five symbol pairs, not six.
Point-to-point b What do physical layer standards govern? Connectors and physical transmission. Frames and switch operation. The answer is not directly in the text. It requires you to integrate the information you have learned. Data link layer e At what layer are frames defined? Data link layer It breaks the standardization job into smaller pieces that can be worked on by specialists in that area.
Physical layer, Layer 1 c What is the name and number of the second-lowest network standards layer? Data link layer, Layer 2 d At which layers are standards defined for single-network technologies?
Layers 1 and 2 e At what layer or layers is PPP a standard? Layer 2 because it defines frame organization. Wireless Single Networks Wireless access point. Frame organization and access point operation c Is there always a single data link for a frame in a single network? Yes Switched Single Networks Where to send it next b What is this decision called?
The switching decision c How do they make this decision? Only the next hop. The answer is not in the text. Destination hosts. Switches merely read the DLL address in the frame in order to pass it on to the destination host with the destination DLL address.
Yes b In a hybrid single-switched network, why do wireless clients need to connect to the wired network?
They translate between wireless client frames and wired network frames. If two hosts are on two different single networks, what three problems must be overcome if they are to be able to communicate?
First, the single networks may have different standards. Second, even if the two networks follow the same standard, this does not mean that they can interoperate. Most fundamentally, a host on one network may have the same DLL address as a host on the other network.
Third, how would you link the two networks together? If the link used the standards of one network, it would not connect to the other network for the first two reasons. Creating the Internet A router b Do single networks know that they are delivering frames to a router? No c To what type of device do single networks think they are delivering frames?
A destination host d What devices understand what is really happening? The router and the source and destination host A Diff: Explain how internet standards are made and why this approach is valuable. A semantics B syntax C rules D protocols Answer: D Diff: Provide the definitions of network standards and protocols, message syntax, semantics, and order.
C Diff: A protocol B order C syntax D semantics Answer: A protocol B message order C meaning D structure Answer: A browser B Webserver application program C They transmit simultaneously.
D It depends on the situation. Application 14 In a four-step close, which side transmits a FIN segment?
Business Data Networks and Security (10th Edition)
A the side that initiates the close B the other side C either side D neither side Answer: B Diff: A address field B header C data field D trailer Answer: Application 19 Which part of a message is less often in a message compared to the other two parts? A header B data field C trailer D All of the above are commonly seen in all messages.
A 32 bits long B 48 bits long C bits long D Address length varies. A 4 bits B 32 bits C 48 bits D bits Answer: Concept 28 How long are IPv4 addresses in octets? A 4 octets B 32 octets C 48 octets D octets Answer: A reliable B unreliable C semi-reliable D unreliable or reliable depending on the situation Answer: A segments B fragments C packets D datagrams Answer: A reliable B unreliable C It depends on the situation. D none of the above Answer: Application 41 The source socket is A client B server C well-known server D ephemeral server Answer: Application 42 Which of the following is a socket?

C ; D none of the above Answer: A encapsulation B encryption C encoding D exchange Answer: Explain how to encode application messages into bits 1s and 0s.The PC doing the configuration finds them and does the configuration work.
