A transport layer protocol has several responsibilities. One is to create a process-to-process (program-to-program) communication; TCP uses port (71) to accomplish this. Another responsibility of a transport layer protocol is to create a (72) and error-control mechanism at the transport level. TCP uses a sliding (73) protocol to achieve flow control. It uses the acknowledgment packet, time-out, and retransmission to achieve (74) control. The transport layer is also responsible for providing a connection mechanism for the application program. The application program sends (75) of data to the transport layer. It is the responsibility of the transport layer at the sending station to make a connection with the receiver.(71)
TCP functions at the Open System Interconnection(OSI)(61)layer, or Layer 4. Its chief responsibility is to ensure(62)end-to-end connectivity. IP, located one layer down, at the OSI network layer, or Layer 3, communicates the addresses of each(63)sender and receiver to the routers along the way. Routers and Layer 3 switches can read IP and other Layer 3(64). This information, combined with routing tables and other network intelligence, is all it takes to get(65)the room or around the world via TCP/IP.

The TCP/IP network model differs from the more popular OSI model. Which of the layers below belong to the TCP/IP model?()
The use of network( ),systems that effectively isolate an organization&39;s internal network structure from an( )network, such as the INTERNET is becoming increasingly popular. These firewall systems typically act as application-layer( )between networks, usually offering controlled TELNET, FTP, and SMTP access. With the emergence of more sophisticated( )layer protocols designed to facilitate global information discovery , there exists a need to provide a general ( )for these protocols to transparently and securely traverse a firewall.

The diffserv approach to providing QoS in networks employs a small, well-defined set of building blocks from which you can build a variety of( ). Its aim is to define the differentiated services (DS) byte, the Type of Service (ToS) byte from the Internet Protocol Version 4 ( )and the Traffic Class byte from IP Version 6, and mark the standardized DS byte of the packet such that it receives a particular forwarding treatment, or per-hop behavior (PHB), at each network node. The diffserv architecture provides a( )within which service providers can offer customers a range of network services, each differentiated based on performance. A customer can choose the ( )level needed on a packet-by-packet basis by simply marking the packet&39;s Differentiated Services Code Point (DSCP) field to a specific value.This ( ) specifies the PHB given to the packet within the service provider network.
In the open systems interconnection (OSI) reference model, "layer" means one of seven conceptually complete,(71) arranged groups of services, functions, and protocols, that extend across all open systems.Application layer provides means for the application(72) to access the OSI environment. Presentation layer provides for the selection of a common syntax for representing data.(73) layer provides the means necessary for cooperating presentation entities to organize and synchronize their dialog and to manage their data exchange. Transport layer provides a reliable end-to-end data transfer service. Network layer provides for the entities in the transport layer the means for transferring blocks of data, by(74) and switching through the network between the open systems in which those entities reside. Data link layer provides services to transfer data between network layer entities. Physical layer provides the mechanical, electrical, functional, and procedural means to establish, maintain and(75) physical connections for transfer of bits over a transmission medium.
Cloud computing is a phrase used to describe a variety of computing concepts that involve a large number of computers( )through a real-time communication network such as the Internet. In science, cloud computing is a( )for distributed computing over a network, and means the( )to run a program or application on many connected computers at the same time. The architecture of a cloud is developed at three layers: infrastructure, platform, and application, The infrastructure layer is built with virtualized computer, storage, and network resources. The platform layer is for general-purpose and repeated usage of the collection of software resources. The application layer is formed with a collection of all needed software modules for SaaS applications. The infrastructure layer serves as the( )for building the platform layer of the cloud. In turn, the platform layer is a foundation for implementing the( )layer for SaaS applications.
Routers perform the decision process that selects what path a packet takes. These ( ) layer devices participate it the collection and distribution of network-layer information, and perform Layer 3 switching based on the contents of the network layer ( ) of each packet. You can connect the routers directly by point-to-point ( ) or local-area networks, or you can connect them by LAN or WAN switches. These Layer 2 switches unfortunately do not have the capability to hold Layer 3 ( ) information or to select the path taken by a packet through analysis of its Layer 3 destination address. Thus, Layer 2 switches be involved in the Layer 3 packet ( ) decision process.
