Nt1310 Unit 3 Assignment 1 Network Security

Exercise 7-13 I have to announce everyone in the group that we will not be able to meet the June 1 commitment to ship 100 operating tables to Southeast Surgical Supplies. To be clear, we only have 30 tables on hand as a report of this morning. However, this is not our fault entirely. Six months ago, purchasing warned us about shrinking supplies and suggested we buy as much as we could in advance for the next 12 months. We tried to follow their advice, but we were never be able to buy supplies in advance due to company’s policy about never buying more than three months worth of materials in advance.

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.

I participate in team of FTTX meeting. Engineer and technicians speak about faulty modems and card failures .The team leader has made the work sharing.. In addition;I learned some concepts such as Xdsl,ADSL,DSLAM.Some information about DSL; Digital Subscriber Line, or DSL, is a technology for bringing high-bandwidth connectivity to homes and small businesses over ordinary copper telephone lines. xDSL refers to the family of digital subscriber linetechnologies, such as ADSL, HDSL, and RADSL.

To get started the LAN would be the main configuration for connecting the computers on each floor with star typology. Star topology will connect all nodes individually to a central connection point also known as the switch. A pro with this configuration if a cable fails only one node will be brought down and the rest will continue running. In addition, we can use twisted pair for the wire used to simply to cancel out electromagnetic interface from external sources since there will be multiple computers next to each other. The copper wire will lead to a switch connecting the devices together on the same network.

Task 1 1.1) Design a networked system to meet the given specification. Your design must satisfy the user requirements and be scalable. [3.1] The design of the network system should include: cost, Bandwidth, system growth, applications, communications, and scalability of the system and selection of components. Introduction - Designing the Network In this design I will be listing and discussing, through the different and necessary designing stages, the various elements involved in designing a network that meets the system requirements given by the client.

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

Hi Friends! I am describing here about the Newstarads.com which I have faced some days ago in my computer system. I am just explaining here that what are the real malicious works of this virus when it attacks into your PC. Newstarads.com is a noxious site. The domain is related to a browser hijacker.

1. Discuss the differences and similarities between a peer-to peer network and a client server network. Answer: The following are characteristics of a peer-to-peer network that differ from those of a client server network.

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.

3.4. Structure 3.4.1. CMS layout This site needs three custom Cascading Style Sheets for each device: desktop/laptop, tablet and mobile phone to be fully responsive (custom.css, custom_tablet.css and custom_phone.css).

Gardner explained the rational around why all this can be important and the question I need to ask myself is based on the points that have been raised by Gardner above. 1) Do I have the creating capability in within me? I think I do but not as high as I would believe it to be and as such most of the work that I do is being replaced by technological breakthrough everyday 2) Do I have the synthesizing capability?

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.

SCENERIO Baxter, a year three Aboriginal student who at age three developed a sensorineural hearing impairment after repeated exposure to Otitis Media. Baxter uses a cochlear implant on one ear, as the other was not viable. Unfortunately, due to bullying in previous years Baxter has limited confidence in his communication skills and will rarely speak aloud, except with the teacher privately, close friends, and family. Baxter often communicates using basic sign language, but relies heavily on gestures. He is currently working with a speech therapist to increase his speech and language skills and to increase his confidence.

Security threats End user computers could be exposed to a multitude of threats anytime because they are very vulnerable without any implemented security measures. They could affect also the computers’ employees within an organization when no network security policies are applied. Security threats can be categorized as it follows: • Virus • Worm • Trojan Horse

P3 - describe how software and network security can keep systems and data secure Introduction In this assignment I will be describing how software and network security can keep and maintain computer systems and data or information secure. I will be talking about things like: encryption techniques eg public and private key; diskless networks; use of backups; audit logs; firewall configuration; virus checking software; use of virtual private networks (VPN) and etc. And for M2 part, I will be explaining how the operation and use of an encryption technique ensure security of transmitting data. Encryption techniques eg public and private key Encryption is the translation of electronic data into another form which is known as cipher text, that
