Computer Networking Topologies and Media
Bluetooth wireless technology is a specification for a wireless connection that provides
links between mobile computers, mobile phones, other portable handheld devices, and
connectivity to the Internet. More ...
Computer Network Routers, Hubs, and Switches
The most common components on a computer network, not counting cables, are "routers",
"hubs", and "switches". Many of these modules can be appear similar and there can be
significant overlap in roles. This article explains the difference between these
important network components. More ...
In 1973 Xerox invented Ethernet to solve the problem of transferring data between computers.
In the early 1980s Xerox turned over control of the Standard to the Institute of Electrical
and Electronics Engineers (IEEE). The IEEE subcommittee 802.3 sets the standard for Ethernet. More ...
Static Versus Dynamic Routing
Routers direct traffic between networks or subnetworks. With static routing a network administrator manually
creates the router's routing table. With dynamic routing the router learn about networks use routing protocols
like RIP, RIP2, EIGRP, OSPF, or BGP. More ...
What Are Fiber Optic Attenuators?
A fiber optic attenuator, also called an optical attenuator, simulates the loss the would
be caused by a long length of fiber. For a fiber optic receiver, too much light can overload
it and degrade the bit error ratio. More ...
LAN Network Protocols - Ethernet, STP, Fiber
Spanning Tree is an algorithm that runs on Layer 2 campus switches for preventing
Layer 2 loops and broadcast storms on a network with at least 2 switches or bridges.
The algorithm determines what ports at each switch or bridge must be blocked to
create a loop free topology. More ...
Cable: Cat5, Cat5e, Cat6, Cat6A ; What's the Difference?
This article describes the different twisted pair cable types, Cat5, Cat5e, Cat6, Cat6A, their construction and application. More ...
How to Set up a Private Network
A private network is one which does not connect directly to the internet, but does allow you
to connect to other computers that are on the same physical network. More ...
The physical arrangement of the cables, computers and components is referred to as the networks
topology. There are five basic topologies, bus, star, ring, mesh, and wireless. More ...
What Are Fiber Optic Circulators?
An optical circulator is an nonreciprocal passive device that directs light sequentially
from port to port in only one direction. The operation of a circulator is similar to that
of an isolator except its constructions is more complex. More ...
Overview of IEEE 802.11 Wireless Lan Technology
Wireless LAN (WLAN) is a wireless broadband technology that utilizes radio frequency (RF) to
transmit and receive data through the air There are two competing RF technologies in the use
of Wireless LAN, the IEEE 802.11 standard and proprietary technologies. Both fall under wireless
broadband technology. More ...
Data Center Management Best Practices
The use of an integrated best practices approach to data center management involves
efficient management of resources while still minimizing the costs of all the different
interrelated competing factors that require attention. More ...
