Faster call setup No interference between signaling tones by network and frequency of human speech pattern. Greater Trunking Efficiency:- CCS has shorter call set up and tear down times that result in less call holding time, thereby reducing the traffic on the network. Information Transfer:- CCS allows the transfer of additional information along with the signaling traffic providing facilities such as caller identification and voice or data identification

Client-Server Application Connection Oracle Net enables a network connection between a client and an Oracle database server. Oracle Net is a software component that resides on both the client and on the Oracle database server. It is layered on top of the network protocol. When a connection is initiated from a client to the Oracle database server, data is passed down a stack on the client, over the network, and up a similar stack to the Oracle database server.

Two-Tier Networks In a two-tier network, a client communicates directly with a server. This is also known as a client-server architecture. A client-server network is an architecture that involves client processes that request services from server processes. The client and server communicate over a network using a given protocol, which must be installed on both the client and the server. A common error in client-server network development is to prototype an application in a small, two-tier environment and then scale up by adding more users to the server.

Cryptography (or cryptology; from Greek κρυπτός, "hidden, secret"; and γράφειν, graphein, "writing", or -λογία, -logia, "study", respectively)[1] is the practice and study of techniques for secure communication in the presence of third parties (called adversaries).[2] More generally, it is about constructing and analyzing protocols that overcome the influence of adversaries

Khi web ra đời trong những năm đầu thập kỷ 90, nó lập tức thay đổi cách con người giao tiếp và tiếp nhận kiến thức. Ban đầu, web chỉ là một đại lượng tĩnh với các trang HTML cơ bản. Sau đó, XML, SOAP (Simple Object Access Protocol Giao thức tiếp cận đối tượng đơn giản) và những công nghệ khác đã mở ra thế giới của SOA (service-oriented architecture - kiến trúc hướng dịch vụ) và làm biến đổi hoàn toàn cách các ứng dụng, hệ thống và doanh nghiệp kết nối với nhau.

Multiprotocol Label Switching Multiprotocol Label Switching (MPLS) is a standards-approved technology for speeding up network traffic flow and making it easier to manage. MPLS involves setting up a specific path for a given sequence of packets, identified by a label put in each packet, thus saving the time needed for a router to look up the address to the next node to forward the packet to. MPLS is called multiprotocol because it works with the Internet Protocol (IP), Asynchronous Transport Mode (ATM), and frame relay network protocols....
