• TCP/IP.
Transmission control protocol/internet protocol. The basic communication protocol
(or language) of the internet that has become the global standard for network
communications since it ensures faithful data transmission. TCP/IP uses the
client-server communication model, in which a computer user (client) makes
requests and is provided services by a network computer (server).
TCP/IP is a multi-layered protocol. In the transport layer, TCP ensures delivery
of the entire file/message. TCP manages the assembly of files/messages into
"packets" that are transmitted to and received by another TCP layer. That TCP
layer then reassembles the packets into its original format. In the network layer,
IP routes the data to different destinations (LANs or WANs) based on the network
address. TCP/IP is a routable protocol, which ensures that all messages contain
the address of both the destination computer (station) and destination network.
This makes it possible for messages to be transmitted to multiple networks.
• UEFI.
Unified Extensible Firmware Interface. The interface between the operating system
and the hardware. It is also responsible for booting the operating system when a
unit is turned on. On legacy computers, this was referred to as a BIOS, and in
some menu items, BIOS and UEFI are still used interchangeably.
