TWISTED MIND OF THE GRIM REAPER A handsome young man hobbling furiously on his crutches requests a beautiful young woman to assist him to his vehicle. She cannot help but to be drawn towards his charismatic persona‚ completely taken in by his easy charm. Suddenly‚ her face is a mask of horror as the cold smiling gentleman raises his arm to bludgeon her. Her anguished screams reverberate in the cold night. This was how notorious serial killer Ted Bundy lured his victims and sexually assaulted

Three”. User workstations and servers are often identified with “Layer Seven”. HUB Hub is a hardware device that contains multiple‚ independent ports that match the cable type of the network. Most common hubs interconnect Category 3 or 5 twisted-pair cable with RJ-45 ends‚ although Coax BNC and Fiber Optic BNC hubs also exist. Ethernet Hubs An Ethernet hub is also called a multiport repeater. A repeater is a device that amplifies a signal as it passes through it‚ to counteract the effects

input device) Cabling eg coaxial‚ optical‚ twisted pair In cabling you have a coaxial cable‚ optical cable and a twisted pair cable. Coaxial cable is mostly used on computers out of the three. Coaxial was used in the 1980’s and early 90’s‚ however they started using it again with broad band and also is used for connecting a dish from a TV to the roof. The data transfer rate of the coaxial cable is 100 Mbps (Megabits per second). Coaxial and twisted pair uses copper cables to transfer their data

Transmission impairments ∗ Attenuation ∗ Twisted pair has more attenuation than coaxial cable which in turn is not as good as optical fiber – Interference ∗ Can be minimized by proper shielding in guided media – Number of receivers ∗ In a shared link‚ each attachment introduces attenuation and distortion on the line Guided transmission media • Transmission capacity (bandwidth and data rate) depends on distance and type of network (point-to-point or multipoint) • Twisted pair – Least expensive and most widely

Each wire pair is twisted many times per foot (higher grade UTP cable can have more than 20 twists per foot). The twists serve to cancel out electromagnetic interference that the trans-mission
