A subnet mask is used to detect the IP address that is reserved for your network and the one available for use by the host. The subnet mask offers you all the information that you need to calculate the network and host portions of the address with great ease. With the subnet mask you can calculate whether the IP addresses are in a similar subnet.
The subnets are necessary for the IP network communications to carry on. The network devices use the IP addresses and a defined subnet mask to determine if the host is on a remote subnet or local subnet.
It makes it easy to identify the number of hosts capable of being included on the same subnet.
Global Systems for Mobile (GSM) is a 2G technology used by many countries worldwide. The many phones supported by GSM are becoming cheap with people looking for an alternative way of communicating has many goals and one of them is to support international roaming as well as broaden the spectrum of efficiency supports new services, has low costs for mobile sets and compatibility features with other telephones.

A codec refers to an algorithm that is used to decode and encode voice conversation in VOIP. The sound and voice that human beings hear is in analogue form and has to be converted to digital to make it possible to transmit it over the internet. The sound or voice has to be converted back to analogue once it reaches the receiving end so that it can be heard.
There are various ways that the decoding and encoding can be done but the majority of them use compression. This method ensures that the bandwidths are reduced. If the compression is heavy, there is usually a delay in the conversation because it takes time. It is possible to find a VoIP codec that will take a minimum amount of time.
Public Key Infrastructure is basically a combination of processes, people and hardware for the management, annulment, and storage of various digital certificates. PKI users can network confidentially without worrying about insecurity on the networks. The digital signature is by far the most vital component in the digital certificate.
The certificate authority assists you in getting the PKI certificate as they asses the validation process and confirm the identity of the applicant. The keys included in the certification have the components such as certification management system, certificates directory, A registration authority and A certificate Authority.
There are public and private certificates and they both are aimed at authenticating the process in the unsecured networks like the internet.Using a central database you can encrypt a message.
SPDIF is an abbreviation for Sony/Philips Digital Interconnect Format and refers to an audio format that is digital. It is used to transport stereo audio signals that are digital on CD players, car audio systems, DVD players, PC audio cards and any other system that transmits or receives stereo audio that is digital.
The SPDIF connector does not determine the rate at which the data is sent or received since it is the equipment that it is contained in that does this. The data that is transmitted by the SPDIF cable is through a data word stream of 32-bit. The connector has some interface that work with it when the compressed data is being transferred and also to make connections with various audio equipment.
