Twisted Pair Cable

• Relatively slow speed
• Two insulated wires can be shielded (STP0 or unshielded (UTP)
• UTP is four-pair medium and comes in several categories
• UTP can be easily tapped by eavesdroppers than the other cable types
• Category based on how tightly wound the wires are, the tighter the wind the higher the rating and the higher the resistance to interference
• Cat 1 UTP – was used for telephone lines, not good for data
• Cat 2 UTP – up to 4 MBps
• Cat 3 UTP – Used for 10BaseT networks up to 10 MBps
• Cat 4 UTP – Used in Token Ring Networks up to 16 MBps
• Cat 5 – Current UTP standard for new installations up to 100MBps
• Cat 6 UTP – up to 155MBps
• Cat 7 UTP – up to 1 GBps

Coaxial Cable

• Hollow outer conductor surrounds inner wire conductor
• Currently two types of LAN
  • 50-ohm Cable for digital signaling
  • 75-ohm Cable for analog signaling and high-speed digital signaling
• More expensive, but is more resistant to Electromagnetic Interference (EMI)
• Used rarely except in Broadband communications
• Comes in two types:
  • Thinnet – RG58
  • Thicknet RG8 and RG11
• Two common types of coaxial transmission methods:
  • Baseband – The cable carries a single channel
  • Broadband – Cable carries several channels

Fiber Optic Cable

• Conducts modulated light transmission
• Light waves are faster and travel greater distances
• Difficult to tap
• Resistant to EMI
• Usually connects backbones in larger networks
• Can be used to connect workstations to the network
• Expensive to install and to terminate

LAN Transmission Protocols

• Rules for communication between computers on a LAN
• Formatting of the data frame, the timing and sequencing of packet delivery, and resolution of error states

Carrier Sense Multiple Access (CSMA)

• Foundation of the Ethernet protocol
• Workstation continuously monitors the line waiting until it thinks it is free
• If the workstation doesn’t receive an acknowledgement from the destination to which it sent the packet, it assumes a collision has occurred and it resends the packet
  • Persistent Carrier Sense – Unless it receives an acknowledgement it will resend
  • Non-persistent Carrier Sense – Waits a random amount of time before it resends

CSMA/CA

• Carrier Sense Multiple Access / Collision Avoidance
• Workstations connected to two coax cables, one to send and one to receive data

CSMA/CD

• Carrier Sense Multiple Access / Collision Detection
• If the host detects another signal while transmitting it will send a jam signal causing all nodes to stop sending data
• Nodes will wait to resend
• Designed to avoid collisions

Polling

• A primary workstation polls another at a predetermined time to determine if it has data to transmit
• Primary must give permission to others to transmit

Token Passing

• Token Ring, FDDI and ARCnet
• Cannot transmit without the token
• Each station can hold token for maximum predetermined amount of time

LAN Transmission Methods

• Refer to the way packets are sent on the network
• Unicast – from single source to single destination
• Multicast – source copied and sent to multiple destinations
• Broadcast – source copied and sent to all nodes on the network

So What is Affiliate Marketing?

Affiliate Marketing is a way of promoting online business through affiliate programs and advertising that pay the affiliate (or publisher) a type of commission based on the amount of business their website brings the merchant company.

It’s a form of revenue sharing or commission based advertising. The term “affiliate marketing,” however, is often associated with network marketing or multi-level marketing and therefore many companies prefer to use the term “performance marketing”. Affiliate marketing is the most cost effective sort of marketing there is, and is actually incredibly efficient. For this reason, many companies (especially those that started in the early days of e-commerce) owe a tremendous amount to affiliate marketing (amazon.com is a good example) and it has now become normal for companies to include affiliate marketing in many of their plans.

There are three types of compensation methods that are associated with affiliated marketing. The first type is Cost per Click (CPC) or Cost per Mil (CPM.) Basically, the affiliate earns by how many clicks the advertising on hisher site generates, or by just having the advert published on the website. But because of click fraud and many other questionable tactics, CPC is no longer the general form used for affiliate marketing. Generally, companies now either use CPA (Cost per Action) or CPS (Cost per Sale.) The first is based on how much the advert generates interest by the clicker to actually buy or register at the advertised site, the second is based strictly on sales. In other words, an affiliate is paid if the clicker actually purchases something on the advertised site.
