Wireless Networks
A wireless LAN (WLAN or WiFi) provides network connectivity by using radio waves rather than cable. Wireless devices can communicate with each other or they can communicate through a wireless access point (WAP) to a wired network. More ...
Data Center Networking
In recent years, companies such as Amazon, Google, and Microsoft have built massive data centers, each housing tens to hundreds of thousands of hosts, and concurrently supporting many distinct cloud applications. Each data center has its own data center network that interconnects its hosts and interconnects the data center with the Internet. More ...
Introduction to ATM (Asynchronous Transfer Mode) Networks
ATM (Asynchronous Transfer Mode) is a network technology to provide broadband services for the transmission of voice, video, and data at speeds up to 1Gbps. More ...
Difference Between Unmanaged, Web Smart and Managed Switch
A network switch is used to route data over a communication network. There are four major types of a switches. It can either be an unmanaged switch, a managed switch, a smart switch or an enterprise managed switch. Each kind of switch has its own strengths and weaknesses. 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 ...
Wireless Networking Infrastructure Mode
In Ad Hoc mode devices make wireless connections directly between computers, Infrastructure mode wireless devices use access points (WAPs), switches, and routers to connect. More ...
The IEEE 802.3 Ethernet Standards
The Institute of Electrical and Electronics Engineers (IEEE). The IEEE sets up committees to define industry standards. The IEEE 802 committee sets the standards for networking. The IEEE subcommittee 802.3 sets the standard for Ethernet. 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 ...
Routers
Routers are sometimes confused with network hubs, modems, or network switches. However, routers can also provide additional features such as embedded firewall and content filtering software that provides an additional protection from unwanted content and malicious websites. More ...
System Area Network Interface Cards
Whereas the standard network may use twisted-pair cabling, the System Area Network may use separate fiber-optic cabling. System Area Network interface cards are special high speed circuits that provide communications between the servers over the System Area Network. More ...
The Difference Between a Hub and a Router
For someone who needs a quick clarification on the matter, a hub combines all linked computers or workstations into a network, while router links two separate and distinct networks to each other. More ...
Access Points and Wireless LAN Controller
An access point is a network device that creates a wireless LAN (WLAN) and might also connect to a wired router to allow wireless devices to connect to the wired LAN. More ...
How In-Row Cooling Increases Data Center Efficiency
Increased data center densities enable operators to meet the demands of cloud and hyper-scale environments. As more power is consumed per rack, however, heat becomes a big problem. Most modern data centers have adopted some sort of aisle-containment solution to minimize the mixing of hot and cold air. More ...
