1.3 How do local area networks (LANs) differ from wide area networks (WANs) and backbone networks (BNs) Local area networks are limited within an organization Wide area networks extend over a large geographical distance and may be privately owned or rented Backbone network are the part of network infrastructure that feeds the connected networks 1.8 Describe the seven layers in the OSI network model and what they do. Application – this layer is specific to applications and provides services such as email, network software services and file transfers Presentation - In this layer, the data is formatted in a schema that network understands, and also manages data encryption and decryption Session – this layer establishes and controls the data communication between …show more content…
This provides a means of communication that can help different vendors packages to communicate and manages the message transfers from clients to servers. 2.10. Compare and contrast the three cloud computing models. Three cloud computing models • Infrastructure as a Service (IaaS): IaaS contains basic building blocks for cloud infrastructure and provides access to networking features, computers and data storage. This model provides highest level of control, flexibility and management over the IT resources • Platform as a Service (PaaS): Platform as a service removes the need for organizations to manage the underlying infrastructure (usually hardware and operating systems) and allow you to focus on the deployment and management of your applications. This model helps one to be more efficient. • Software as a Service (SaaS): This is top layer of cloud computing platform. This platform is typically built on top of a Platform as a service solution. Software as a service (Saas) provides not only hardware infrastructure but also an operating system and application program on top of that
I. Site “Springfield” Device and STP Configurations Site Details and Challenges (Summary) This section will implement device hostnames (to correlate with the xACME educational topology labels), provide a sample configuration for the MOTD and login banner, and provide configuration steps for applying device passwords (encrypted) on the console port and VTY. This section will also review what the Spanning Tree Protocol (STP) does, its benefits, and provide a sample configuration for applying STP on the switches. Security methods that can be applied to the devices will be reviewed as well.
HOMEWORK ASSIGNMENT 1 PROF: TOM WILKES FALL 2015 AKHILA DAMERA 1. What is the purpose of an interrupt? Answer: An interrupt is a signal from software or hardware. It indicates the occurrence of an event.
1. Request: The industry of construction is an industry where a firm has to be precise and very accurate. This is why I will be requesting that the superiors in my company purchase a piece of software Chief Architect, and revert from using their current software Sketch-up. This task will require persuading because the owners of the company think that using open-source software like Sketch-up will be sufficient.
2.1 AWS Networking AWS provide a kind of networking services that also provide private network connections to the cloud, scalable DNS and tools to make logistically solitary networks. There are also have prevalent networking services comprise the Amazon Virtual Private Cloud (VPC) and Amazon Direct Connect. Amazon VPC generates a logically solitary set of Amazon EC2 for example which can be connected to current network using VPN connection. Amazon VPC generates a private cloud inside AWS, while deposition built-in security with security groups and network access control lists. When using Amazon EC2, VPC is free.
In order to access a UNIX system, and use it , you need to connect to the system. You can login: Locally Remotely Login Types In general, there are two ways: Command-line Login GUI Login Connecting Locally Connecting locally means, you are directly logging into the UNIX system. Network connectivity is not required.
msxml6.dll download free and error fixing Like any other DLL file, the msxml6.dll file gives rise to a lot of problems as well quite frequently, irrespective of the version of windows the users are dealing with. In most of the times, these problems lead to serious glitches, which cannot be solved with the help of the online error fixer tools and troubleshooting steps, which on majority of the cases are open source. In these circumstances, these individuals have to turn to certain tools that are specifically developed to deal with these issues. There are instances, when those with Windows 10 find after they have installed windows or have upgraded from a lower version of windows to version 10, they keep on getting intermittent pops ups asking them to install as driver for a printer, though they do not have any printer installed, or have the need to do so. At times, they get a msxml6.dll' should be excluded because its source file is either missing or not found error.
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.
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
Moving forward, now we will discuss two elements of IaaS and they are the benefits and the limitations. Commencing with the benefits, there are 5 benefitical factors we will highlight which includes Scailability, Reduction in down time, Minimal maintenance of hardware, Cost savings and enhanced Security & Disaster Recovery. Beginning with Scalability, this is considered as a top and most popular benefit that IaaS has to offer. It kicks the traditional infrastructure out the window and you have the ability to scale up your system and it is on demand. This is done efficiently, quickly and in addition to this, it does minimise downtime in which we will cover more as we move forward in this discussion.

1. The operating system I am using is windows 7 and it allows me access Word, Excel, Access and PowerPoint. 2. A user interface is the way in which the user will interact with the computer system and all the apps that are available on the computers software. The components of a user interface is navigation mechanism, input mechanism, and output mechanism.
You need to understand your existing network infrastructure to determine how well it can meet the needs of your deployment goals. By examining your existing infrastructure, you identify if you need to upgrade existing network components or purchase new network components. You should build up a complete map of the existing network by covering these areas: 1. Physical communication links, such as cable length, grade, and so forth 2. Communication links, such as analog, ISDN, VPN, T3, and so forth, and available bandwidth and latency between sites 3.
Anywhere, Any Time Collaboration : Software as a service can act as a great simplifier for many organizations. Minimal downtime, dependable uptime. No in-house IT crisis management. No need to go into office, work anywhere and at anytime. Employees can sync up and work wherever they are.
Certain amount of resources are required for running VMs as they are different for VM in different classes. • Each cloud provider supplies a pool of resources. Resources are grouped into resource types are they include computing power (in unit of CPU-hours), storage (in unit of GBs/month) and network bandwidth for data transfer (in units of GBs/month). • Each VM class specifies the amount of resources in each resource type. • Cloud providers offer reservation contracts that is to be considered when making reservations.
