Networking Fundamentals

Objectives• Describe how networks impact our daily lives.• Describe the role of data networking in the human

network.• Identify the key components of any data network.• Identify the opportunities and challenges posed by

converged networks.• Describe the characteristics of network

architectures: fault tolerance, scalability, quality of service and security.

• Install and use IRC(Internet Relay Chat) clients and a Wiki server.

How Networks Impact Daily Life

• Explain the benefits of instantaneous communication and how it supports and improves our lives.

How Networks Impact Daily Life• Describe the characteristics and purpose of

popular communication media such as, IM, Wikis , Blogs, Podcasting, and Collaboration Tools– Instant messaging

• Real time communication • between 2 or more • people based on typed text

– Weblogs (Blogs)• Web pages created • by an individual

– Podcasting• Website that contains• audio files available• for downloading

How Networks Impact Daily Life

• Explain ways that using information networks to share and collaborate improves teaching and learning

How Networks Impact Daily Life

• Describe ways communication over a network changes the way we work

How Networks Impact Daily Life

• Describe ways communication over a network supports the way we play

Data Networking Role, Components, and Challenges

• Basic characteristics of communication– Rules or agreements are first established– Important information may need to be repeated– Various modes of communication may impact

the effectiveness of getting the message across.

Data Networking Role, Components, and Challenges

• Describe the role of data networking in communications

Data Networking Role, Components, and Challenges• Describe the various

elements that make up a network– Devices

• These are used to communicate with one another

– Medium• This is how the

devices are connected together

– Messages• Information that

travels over the medium

– Rules• Governs how

messages flow across network

Data Networking Role, Components, and Challenges

• Describe the role of converged networks in communications– Converged network

• A type of network that can carry voice, video & data over the same network

Network Architecture Characteristics

• Explain four characteristics that are addressed by network architecture design– Fault tolerance– Scalability– Quality of service– Security

Network Architecture Characteristics

• Describe how packet switching helps improve the resiliency and fault tolerance of the Internet architecture

Network Architecture Characteristics

• Describe characteristics of the Internet that help it scale to meet user demand– Hierarchical– Common standards– Common protocols

Network Architecture Characteristics

• Explain the factors that necessitate Quality of Service and the mechanisms necessary to ensure it

Network Architecture Characteristics

• Describe how QoS mechanisms work to ensure quality of service for applications that require it.

Network Architecture Characteristics

• Describe how to select the appropriate QoS strategy for a given type of traffic

Network Architecture Characteristics

• Describe why networks must be secure

Network Architecture Characteristics

• Describe basic measures to secure data networks– Ensure confidentiality through use of

• User authentication• Data encryption

– Maintain communication integrity through use of• Digital signatures

– Ensure availability through use of• Firewalls• Redundant network• architecture• Hardware without a single • point of failure
