WHAT YOU NEED TO KNOW
The protective coating around the cladding is called the buffer. This prevents light from entering the
fiber cable and helps to bounce the light signal back into the core.
A mesh conductor is part of a coaxial (coax) cable that serves both as shielding from Electromagnetic
Interference (EMI) and as a ground. It is not found in fiber optic cables.
A BNC (Barrel Nut Connector) coupler is used only on coaxial cables. The technician would need a
crimper for an Ethernet cable.
T568A and T568B are two methods for terminating RJ-45 connectors defined by the ANSI/TIA/EIA.
T568A is mandated for US government premises and by the residential cabling standard (TIA 570).
A straight tip connector (ST connector) is a connector used in fiber-optic cables that utilizes a bayonet-
style plug and socket; used mostly for multi-mode networks. The ST connector setup allows for
unidirectional communication, so two ST connectors and two fiber cables are used for bidirectional
communication.
Coax installations use screw-down F-connectors. A broadband cable service, for example, is likely to use
the F-connector for drop cables.
Twisted pair cabling for Ethernet is terminated using module RJ-45 connectors. RJ-45 connectors are also
referred to as 8P8C, standing for 8-position/8-contact.
A BNC (Bayonet-Neill-Concelman) connector is a miniature quick connect/disconnect radio frequency
connector used for coaxial cable.
Cat 6A uses 500MHz and carries 10Gbps of data up to 100m (328ft) and is used in 10GBASE-T networks.
Cat 5 uses 100MHz and carries 100Mbps of data up to 100m (328ft) and is used in 100BASE-TX networks.
Cat 6 uses 250MHz and carries 1Gbps of data up to 100m (328ft) and can carry 10Gbps of data up to
55m (180ft). 1Gbps is used in 1000BASE-T networks and 10Gbps is used in 10GBASE-T networks.
Cate 5e uses 100MHz and carries 1Gbps of data up to 100 (328ft) and is used in 1000Base-T networks.
The four cloud deployment types are public, private, community, and hybrid. Public clouds are available
to anyone. Private clouds are available only to an organization. Community clouds are available only to a
certain group. Hybrid clouds are a combination of cloud types such as public and private.
Resource pooling cloud services involve resources that are shared and in use by multiple customers.
With resource pooling, a service provider can allocate and de-allocate resources to customers as needed
from an overall environment such as a single server. An example of resource pooling is shared web-
hosting. With shared web-hosting, web content from each customer is assigned a portion of the server,
