• “Application - The Application Layer is the layer that most network users are exposed to, and is the level at which human communication happens. HTTP, FTP, and SMTP are examples of the application layer protocols the Patton-Fuller will now be utilizing for communicating electronically” (Network Design, 2012).

Bandwidth: Is the bits per second that a link is capable of transmitting (ie: Exetel currently advertise their ADSL2+ connections to be up to 20,000/800kbps Download/Upload bandwidth)

Gigabit ethernet connections for both the WAN and LAN ensure the fastest file transfer speeds available. This prevents any bottlenecks between the router and modem to take full advantage of your high speed internet connection. Additionally, file sharing between up to 4 ethernet connected home computers will be lightning fast.

Joined in a ring or star topology and a bit-or token-passing plan is utilized as a part of request to keep the impact of information between two PCs that need to send messages in the meantime.

Sockets is the form of communication (UDP and TCP) use the socket abstraction, which provides an endpoint for communication between processes to processes. Interprocess communication consists of transmitting a message between a socket in one process and a socket in another process. As the IP packets underlying UDP and TCP are sent to Internet addresses.

11. Today, most wireless local area networks use the _____ standard, which can transmit up to 54 Mbps and has a range of about 300 feet.

How would you define a network? What is bandwidth? What is a NIC? List three types of media used for network connections.

6. Why is Ethernet technology more appealing to users than the rest of the LAN technologies?

24. Pg 6 Phase 2 Infrastructure. Bell/AT&T were the first. Microprocessors and packet switching also were part of the new way.

before the client does, and waits for the client to request connections. Figure 3.11 shows the

Topic 3: SOHO Broadband Level 1: Definition Question: Describe popular broadband solutions available to consumers in today’s market.     Topic 3: SOHO Broadband Level 1: Definition Answer: Brief definition of broadband technologies, such as ADSL, Cable Modem, and Satellite feed. A comparison and contrast of these technologies will be a plus.     Topic 4: TCP/IP Level 3:

12. A TCP/IP network includes an Ethernet LAN with 10 PCs uses a LAN switch. PC1 sends data intended for an app running on PC2. Which of the following mechanisms does Ethernet define so that PC2 receives and processes the data? A)The Ethernet header lists PC2’s MAC address so that PC2 will realize that the data is meant for PC2.

If a device does not know how to get to a destination, it sends data to this device.

The Modern Mouldings current wired infrastructure will be appraised based on the following qualities. Speed, Topology, Scalability, Cost, Reliability and Availability.

Advancements in the information technology sector have brought many benefits to the people all around the world.  Today with computer networking, we can chat, speak and see each other over a long distance. Data communication refers to the transmission of the digital signals over a communication channel between the transmitter and receiver computers. Communication is possible only with wired and wireless connectivity of the computers with each other.
