When we first heard the word QoS or Quality of Service we would interpret it as the quality of a service. In fact, Quality of Service (QoS) is very popular and save a lot of terms that are very often seen from different perspectives namely in terms of networks (networking), application development (application development) and others.
In terms of networking, QoS refers to the ability to provide different services to network traffic with different classes. The end goal of QoS is to provide a better service network and planned to dedicated bandwidth, controlled jitter and latency and improve loss characteristics. Or QoS is the ability to guarantee delivery of critical data flow or in other words, a collection of various performance criteria that determine the satisfaction level of usage of a service.
Quality of Service (abbreviated as QoS) is a mechanism that allows applications or services can operate as expected.
Quality of Service (QoS) refers to the capability of a network to provide better service to selected network traffic over various technologies, including Frame Relay, Asynchronous Transfer Mode (ATM), Ethernet and 802.1 networks, SONET, and IP-routed networks that may use any or all of these underlying technologies. The primary goal of QoS is to provide priority including dedicated bandwidth, controlled jitter and latency (required by some real-time and interactive traffic), and improved loss characteristics. Also important is making sure that providing priority for one or more flows does not make other flows fail. QoS technologies provide the elemental building blocks that will be used for future business applications in campus, WAN, and service provider networks.
Quality of Service (QoS) is used to measure the level of quality network connection TCP / IP Internet or intranet. There are several methods for measuring the quality of the connection as the bandwidth consumption by user, connection availability, latency, losses etc.. Now we discuss the term - a term in the Quality of Service,
Bandwidth
Bandwidth is the capacity or the capacity of an ethernet cable in order to pass traffic in a certain amount of data packets. Bandwidth can also mean the amount of consumption of data packets per unit time is expressed with units of bits per second [bps]. Internet bandwidth provided by the internet provider or ISP that we are familiar with a certain amount depending on the rental customer. With QoS we can set the user does not spend bandwidth provided by the provider.

latency
If we transmit data at 3 Mbyte at network quiet time 5 minutes but at busy 15 minutes, this is called latency. Latency when the network is busy around 50-70 msec.

losses
Losses is the number of packets lost during transmission of data packets to the destination, the best quality of network LAN / WAN has the least amount of losses.
Losses is the number of packets lost during transmission of data packets to the destination, the best quality of network LAN / WAN has the least amount of losses.
Availability
Availability means the availability of a web services, smtp, pop3 and applications at the network LAN / WAN busy or not.
