Different Types Of Computer Protocols

TCP/IP is a protocol which transfers data across a network. It allows two different computers to communicate well even if they use different codes. Putting both computers into a new common code language which both computers

Which of the following is protocol used to enable communication securely between points on a Virtual Private Network (VPN)?

In 2003, as an outcome of all the sentinel events reported to the Joint commission lead to the creation of the “The Universal protocol for preventing wrong site, wrong procedures, and wrong person surgery” (Mulloy & Hughes 2008). So, one of the ways that could have potentially prevented the situation from happening at the first place was implementing the universal protocol procedure. According to the protocol the conduction of proper pre as well as post-operating procedures are extremely mandatory. Therefore, by enforcing a standardized routine pre-operating procedure such as verifying the patient as well as the correct site for the procedure, by having the medical staff or preferably the physician marking the operating site with his or her initials before the surgery will be an effective preventive measure (Mulloy & Hughes 2008).

The fifth layer is the session layer this establishes a connection,this layer makes and sets up the connection using co ordinates and could terminate conversations links. the session layer produces services that make authentication after an interruption and not only that but it can reconnect.and as well as the transporting layer it can also have the TCP and the UDP can provide services for all most all applications.An application layer is an abstraction layer that specifies the shared protocols and interface methods used by hosts in a communications network. The application layer abstraction is used in both of the standard models of computer networking; the Internet Protocol Suite (TCP/IP) and the Open Systems Interconnection model (OSI model).Although both models use the same term for their respective highest level layer, the detailed definitions and purposes are different.In TCP/IP, the application layer contains the communications protocols and interface methods used in process-to-process communications

1-2). Now, the importance of protocols when communicating between computers is beyond critical because without the implementation of communication protocols between computers, there is no communication or interaction between computers at all! No communication between company computers and to internet databases would set a company back to the point of extinction.

Handshake: - This sub protocol is used to negotiate session information between the client and server. The session information consists of a session ID, peer certificates, the cipher spec to be used, the compression algorithm to be used, and a shared secret that is used to generate keys.

Handshaking procedure: Is the initial contact between A (client) and B (server) that determines the parameters of the interaction between the two entities. In networking this is

name that other computers use to identify one another in a network. Internet protocol is

The OSI (Open System Interconnection) model is a set of specifications that allow computers around the world to openly communicate. It is pivotal to understanding and developing computer to computer communications in a network. Each layer plays a role in the process of sending and receiving data. The application layer is the top layer (layer seven) it promotes communication between programs and lower-layer network services. The services at this layer allow the network to decipher a program's request and the program to decipher data sent from the network. The Application layer protocols, programs handles formatting, procedure, security, synchronization, and any other requirements with the network. The Presentation Layer (layer 6) acts as a translator. For instance these protocols decode the jpg/jpeg files sent within the Web server’s HTTP response. So, in the last step (the Application layer) we enter the Web address and it took us to the Web site. This step allows us to see the images and content of the site. The Session Layer (layer 5) regulates and controls the communication between two nodes on the network. It is an ongoing exchange of data between the two and keeps the connection between them for the duration. It keeps the communication secure, detects whether or not the communication has been cut off and if it has it determines where to restart the

The internet layer is built up of four core protocols: IP, IGMP, ICMP and ARP. Internet protocol (IP) is responsible for routing, IP addressing and breakdown/reassembly of data packets, address resolution protocol (ARP) is responsible for mapping an IP address to a device on the local network, internet control message protocol (ICMP) provides diagnostic information and error reports on lost packets, internet group management protocol (IGMP) controls who receives IP datagrams in a single transmission. The transport layer is built up of two core protocols: TCP and UDP. Transmission control protocol (TCP) sequences and acknowledges packets sent and their recovery when lost in transmission allowing the computer to make and maintain network conversations where applications exchange data, defined as a connection-oriented protocol meaning the connection is maintained until the programs has finished exchanging data. User datagram protocol (UDP) This is used to transfer small amounts of data when the use of error correction isn’t needed increasing the speed of the transmission, common in multi-player video games as the user will not need to receive packets of past events in the game so the error correction featured in (TCP) would be

Network protocol such as SSH should be used between networked computers. The SSH protocol helps in making a secure connection between computers or devises during information transfer, thus making it harder to hack.

A protocol identifier is nothing but the name of the protocol to be used to fetch the resource, e.g. https://www.youtube.com/.The example uses the HyperText Transfer Protocol over SSL (Secure Socket Layer) (HTTPs), which is TCP/IP protocol used by Web servers to transfer and display Web content securely. The data transferred is encrypted so that it cannot be read by anyone except the recipient. (HTTPs) is just one of many different protocols used to access different types of resources on the net. Several other prefixes exist as listed below:

The application layer: this layer allows different applications to communicate with each other’s. In order to exchange different data over the network connection, the protocols included in this layer set up the standards such as DNS, HTTP, FTP. The data coded in this layer will be encapsulated to transport layer for further packing.

The language protocol is TCP/IP or Transmission control protocol/Internet protocol. TCP/IP is the common language of the Internet that allows the network systems to understand each other (UMUC, 2011). All desktops and laptops have been built with Microsoft Windows Vista with Microsoft Office Suite using Exchange mail server. File servers are all standard build with Microsoft Windows Enterprise Server 2008 R2 operating system. Hardware devices are the standard desktops, laptops, multifunction printer/copy/scan/fax devices, and mobile devices. Weebles, Inc. has an intranet that every employee has access to but not every employee has access to the Internet.

Internet Protocol is the primary protocol in the internet layer of the OSI networking model. IP’s job is to deliver packets from a source computer to a destination computer. As of May 2015, about 97% of web traffic uses IPv4. IPv6 is a 128-bit address. IPV6 is the standard fundamental infrastructure to the internet addressing. It helps us to simplify the transition from ipv4 to ipv6. Mainly ipv6 helps us in TCPIP networking and addressing architecture.
