Cosa (chi) è host-based - definizione

METHOD THAT SERVERS SUCH AS WEBSERVERS USE TO HOST MORE THAN ONE DOMAIN NAME ON THE SAME COMPUTER
Virtual host; Vhost; Add-on domain; Addon domain; Name-based Virtual Host; IP-based Virtual Host; Virtual hosts; Virtual Hosting; Virtual web hosting; Virtual domain

  • Fibre Channel host bus adapter
DEVICE WHICH CONNECTS A COMPUTER, WHICH ACTS AS THE HOST SYSTEM, TO OTHER NETWORK AND STORAGE DEVICES
SCSI host adapter; Host adapter maker; Host bus adapter; Host Bus Adapter; Host adaptor; Host bus adaptor; Host controller; IDE controller; Ide controller; Host channel adapter; IDE Controller
In computer hardware, a host controller, host adapter, or host bus adapter (HBA), connects a computer system bus, which acts as the host system, to other network and storage devices. The terms are primarily used to refer to devices for connecting SCSI, Fibre Channel and SATA devices.

  • Nef and Vpu proteins interact with different regions of tetherin. Nef proteins from SIV interact with the cytoplasmic domain due to the presence of the additional 33 amino acids found in primates. However, these extra amino acids are not present in human tetherin and so in HIV, the Vpu protein instead interacts with the conserved transmembrane domain of tetherin.

This is then followed by local spillover and transmission before becoming an epidemic in a country with sustained transmission. If these stages are all successful, the pathogen then has the potential to reach pandemic status.

AN EVOLUTIONARY CHANGE OF THE HOST SPECIFICITY OF A PARASITE OR PATHOGEN
Host shift; Host-switch; Host switching
In parasitology and epidemiology, a host switch (or host shift) is an evolutionary change of the host specificity of a parasite or pathogen. For example, the human immunodeficiency virus used to infect and circulate in non-human primates in West-central Africa, but switched to humans in the early 20th century.

Virtual hosting

Virtual hosting is a method for hosting multiple domain names (with separate handling of each name) on a single server (or pool of servers). This allows one server to share its resources, such as memory and processor cycles, without requiring all services provided to use the same host name. The term virtual hosting is usually used in reference to web servers but the principles do carry over to other Internet services.

One widely used application is shared web hosting. The price for shared web hosting is lower than for a dedicated web server because many customers can be hosted on a single server. It is also very common for a single entity to want to use multiple names on the same machine so that the names can reflect services offered rather than where those services happen to be hosted.

There are two main types of virtual hosting, name-based and IP-based. Name-based virtual hosting uses the host name presented by the client. This saves IP addresses and the associated administrative overhead but the protocol being served must supply the host name at an appropriate point. In particular, there are significant difficulties using name-based virtual hosting with SSL/TLS. IP-based virtual hosting uses a separate IP address for each host name, and it can be performed with any protocol but requires a dedicated IP address per domain name served. Port-based virtual hosting is also possible in principle but is rarely used in practice because it is unfriendly to users.

Name-based and IP-based virtual hosting can be combined: a server may have multiple IP addresses and serve multiple names on some or all of those IP addresses. This technique can be useful when using SSL/TLS with wildcard certificates. For example, if a server operator had two certificates, one for *.example.com and one for *.example.net, the operator could serve foo.example.com and bar.example.com off the same IP address but would need a separate IP address for baz.example.net.
