SSL technically resides in the application layer, from the developer’s outlook it is a transport-layer protocol. FTP-File Transfer Protocol TFTP-Trivial File Transfer Protocol It is used to transfer files from one computer to another over a TCP network. It is used to transfer files between remote machines over a UDP network. It is defined by RFC 959. It is defined by RFC 1350.

There is several different types of components that enable the internet and help the web function correctly upon your computer. A few of these things are; Uploading and FTP, Web Servers, network routers, proxy servers, ISPs, Web Hosting Services, and Domains. I will be explaining all of these components in as much detail as possible. Uploading This component is when you transmit any file from one computer to another computer, this is usually a much larger file. Most of the webs users would explain this simply as sending it to another computer that is set up to receive it or to send it up onto the internet where several people will be able to access it from their own computers.
If BHE chooses, policyIQ log-ins can be integrated into the internal user directory (such as Active Directory) utilizing LDAPS integration. This requires just a few pieces of information to be exchanged by the BHE IT department and the policyIQ technical team. With this integrated, a user can log into policyIQ using his/her network log-in ID and password, and policyIQ will validate that log-in information to the BHE network. This can be set up for multiple network domains, if users do not exist within a single domain. Single Sign-On (SAML) Connection: It is also possible to integrate policyIQ with the BHE network log-ins for a true single sign-on, where users will not be prompted to log into policyIQ directly, but instead will be validated
Data Communication protocols are formal descriptions of data formats and rules in which the more than one system exchanges data /information. The protocols cover various issues such as authentication, error detection and correction. Popular network communications protocols used are the TCP/IP and User Datagram Protocol (UDP), while TCP is connection oriented once a connection is established, UDP connectionless Internet protocol. The model for information exchange includes the data source which generates the data to be transmitted, Transmitter which converts the data into transmittable signals, Transmission system which carries the data, Receiver which converts received signals into data and Destination which takes incoming data. TCP/IP uses
It offers a secure fitting together between internet browsers and websites, letting you to communicate secretive data online. Physical Layout • Topologies; topology can be measured as a computer-generated nature or construction of a system. This shape does not agree to the real physical plan of the policies on the computer network. • Ring; basically in a ring system each device (workplace, waiter, and copier) is related to two other devices, this systems a ring for the signs to travel around. Each packet of data on the network trips in one way and each device collects each box in turn until the journey 's end device receives it.
Goals of the Lab This lab has many different overall goals that are meant to introduce us to the challenges and procedures of building a preliminary enterprise environment from the ground up. Each task has it’s own set of goals that expose us to important areas of system administration in this type of environment. The lab first introduces us to installation and configuration of an edge routing device meant to handle all internal network traffic between devices, and allow access out to an external network, in our case the Internet. The lab then introduces installation of an enterprise Linux distribution, Red Hat Enterprise Linux 7, which will be used as the main Linux based server in our enterprise environment. We are then introduced to installation of a Wiki
Several components required to implement VPN depends on the type of VPN i-e. Remote Access VPN, or site-to-site VPN. Network design is crucial to decide the throughput, choice of devices and number of users. There are two types of networks where VPN is needed to implement. 1.
The difference between the two and three-tier client/server configuration, are the tiers (layers) that make up the systems. In a two-tier system you have a client and a server, each has the capability of doing the processing for the application (Brown, DeHayes, Hoffer, Martin, & Perkins, 2012). The software is loaded on the client computer, and access the data server directly. In a three-tier system, there is an additional server/computer between the client and data server; this third component contains the business logic or processing for the application (Brown, DeHayes, Hoffer, Martin, & Perkins, 2012; Luke, n.d.). A three-tier configuration could be a web-enabled business application.
In 4th chapter I learned about CPU and other aspects related to it such as RISC and CISC.CPU stands for central processing unit and it is very suitable name for it as it processes the instructions that it gathers from files. Following diagrams explain the basic architecture of CPU: CPU performance is given by the fundamental law: Thus, CPU performance is dependent upon Instruction Count, CPI (Cycles per instruction) and Clock cycle time. And all three are affected by the instruction set architecture. Instruction Count CPI Clock Program x Compiler x x Instruction Set Architecture x x x Microarchitecture x x Physical Design x This underlines the importance of the instruction set architecture. There are two prevalent
What are the two other main thread libraries apart from the PThread library? Answer: The two thread libraries which is involved in the process are 1 .Java thread 2 .Window thread 22. What are the three common models for mapping a user level thread to an operating system kernel thread? Answer: We have different models of threads used for mapping. Also we often use these types of models 1.
Name the two types of pipes an operating system can offer for IPC. How do they differ? Answer: The two types of pipes an operating system can offer for IPC are: naoperating by receiving or giving at once by performing it self. Cooperating Processes are those that can receive and taking at same time Cooperating processes require some type of inter-process communication, which is most commonly one of two types: Shared Memory systems or Message Passing systems. 16.
Communication links, such as analog, ISDN, VPN, T3, and so forth, and available bandwidth and latency between sites 3. Server information, including: o Host names o IP addresses o Domain Name System (DNS) server for domain membership 4. Locations of devices on your network, including: o Hubs o Switches o Modems o Routers
1. I will be able to learn various networking protocols for routing and switching like OSPF, RIP, EIGRP and BGP. As working in the field of network security is my career goal, learning these protocols during my Co – op will help me introduce to the base of core networking. 2. I will be able to design architecture for a communication network.
Repeaters – A repeaters purpose is to transmit and receive signals, the signal that it receives should get regenerated or replicated to send the signal on further. An analogue repeater can only amplify a signal, while a digital repeater can repair a signal to close to its original quality. The Software components which enable the internet access are: Operating systems – so that the PC is able to function with internet protocols and the ISP service. Browsers – so that the PC can reach and display HTTP links NON-essential internet access software: FTP software –File Transfer Protocol software is used to exchange files over the internet. Email software – used for creating, sending, receiving and organizing electronic mail, or email (often a web
