15. Components of a NetworkEnd Devices Some examples of end devices are: Computers (work stations, laptops, file servers, web servers) Network printers VoIP phones TelePresence endpoint Security cameras Mobile handheld devices (such as smartphones, tablets, PDAs, and wireless debit / credit card readers and barcode scanners) W. Schulte

30. Reliable NetworkSupporting Network Architecture As networks evolve, we are discovering that there are four basic characteristics that the underlying architectures need to address in order to meet user expectations: Fault Tolerance Scalability Quality of Service (QoS) Security W. Schulte
31. Reliable NetworkFault Tolerance in Circuit Switched Network W. Schulte
32. Reliable NetworkPacket-Switched Networks W. Schulte
33. Reliable NetworkScalable Networks W. Schulte
34. Reliable NetworkProviding (QoS) Examples of priority decisions for an organization might include: Time-sensitive communication - increase priority for services like telephony or video distribution. Non time-sensitive communication - decrease priority for web page retrieval or email. High importance to organization - increase priority for production control or business transaction data. Undesirable communication - decrease priority or block unwanted activity, like peer-to-peer file sharing or live entertainment W. Schulte

40. Network TrendsCloud Computing There are four primary types of clouds: Public clouds Private clouds Custom clouds Hybrid clouds W. Schulte
41. Network TrendsData Centers A data center is a facility used to house computer systems and associated components including: Redundant data communications connections High-speed virtual servers (sometimes referred to as server farms or server clusters) Redundant storage systems (typically uses SAN technology) Redundant or backup power supplies Environmental controls (e.g., air conditioning, fire suppression) Security devices W. Schulte

50. 1.5 Exploring the NetworkingSummary In this chapter, you learned: Networks and the Internet have changed the way we communicate, learn, work, and even play. Networks come in all sizes. They can range from simple networks consisting of two computers, to networks connecting millions of devices. The Internet is the largest network in existence. In fact, the term Internet means a ‘network of networks. The Internet provides the services that enable us to connect and communicate with our families, friends, work, and interests. W. Schulte
51. Exploring the NetworkingSummary In this chapter, you learned: The network infrastructure is the platform that supports the network. It provides the stable and reliable channel over which communication can occur. It is made up of network components including end devices, intermediate device, and network media. Networks must be reliable. Network security is an integral part of computer networking, regardless of whether the network is limited to a home environment with a single connection to the Internet, or as large as a corporation with thousands of users. W. Schulte
52. Exploring the NetworkingSummary In this chapter, you learned: The network infrastructure can vary greatly in terms of size, number of users, and number and types of services that are supported on it. The network infrastructure must grow and adjust to support the way the network is used. The routing and switching platform is the foundation of any network infrastructure. W. Schulte
