...Before the eighties, computers were large and bulky. IBM and a couple of companies were leading the way towards a smaller PC and mainframes. Intel (which started in the mid-sixties) was starting their own revolution which was making a difference in the burgeoning computer environment. Microsoft and Apple were not yet there, but the biggest thing is that there was no internet. Not like we know it today. No IP Addresses as well. In the seventies, there was a beginning to networking and the IP Addresses. IP Addresses were created as the original Internet routing scheme during this period. The IEEE (The Institute of Electrical and Electronic Engineers) was instrumental in the creation of the five (5) IP Classes. As a matter of fact, these classes weren’t created to meet the needs of an ever expanding Internet. When the IEEE proposed these classes, each of the 5 classes was designed for a specific purpose. For example, Class A (0000) was designed to meet the needs of large networks. This is the reason why this class will only support 126 networks. But each network can support 16,777,214 hosts. Class B (1000) was designed for medium-sized networks. This class will support 16,384 networks and is limited to 65,534 hosts per network. Class C (1100) supports 2,097,152 networks but only 254 hosts per network. In the eighties, things started to happen. Network classes were introduced more, but subnet masks were not available as yet. It wasn’t until the nineties that subnet masks...

...IP Addressing and Routing Problem 1: Default Gateway on PC3 is wrong The default-gateway on PC3 was set to 192.168.1.15. The proper default-gateway is 192.168.1.1. This causes PC3 to be unable to communicate past R3 effectively cutting PC3 out of the network. Changing the default-gateway to 192.168.1.1 brings PC3 into the network and allows communication to and from all other devices. Problem 2: R2’s S0/0/1 is set as a passive interface Since the interface is set to passive it does not send RIPv2 updates over that interface causing R1 to be unable to learn its route. This causes all traffic from R1 destined for R2 to be routed through R3 before going to R2. This problem cause no communication problems with the current topology, but could cause a system breakdown if the serial connection between R2 and R3 goes down. Problem 3: The mask of R2’s Fa0/0 is wrong The current mask is 255.255.255.224 and the proper mask is 255.255.255.240. Although the IP of R2 and PC2 both fall into the same subnet of the current mask no connection problems occur, but if additional PC’s were added and given an IP address within the same mask as PC2 communication problems may arise if that IP is outside the mask on R2. EIGRP Serial Configuration I S3 - FA0/0 and S0/0/1 S5 - This is the autonomous system number. This number must match the configured autonomous system number configured on any neighboring EIGRP devices. S6 - This will enable EIGRP on R2’s Fa0/0 and S0/0/1 S8 - Yes there is...

...1 routing analysis 3 Step 2. Again on each PC, ping the IP address of each PC’s respective default gateway. Record whether the ping worked or not in Table 5. Each ping to the PC has worked to the default gateway. Step 3. From each PC, ping the IP address of the other three PCs. Record the results of each ping in Table 6 with a check mark for a successful ping and an X for a failed ping. None of the PC’s pinged to the other pc’s. Step 5. From each router’s user mode command prompt, ping the IP addresses of each other router. Make notes about which IP addresses can be pinged from each router. Each router has pinged the other routers IP’s on the common LAN subnet but none of the pings worked from a router to each others routers. Step 6. Use the show ip route and show ip routes ospf commands to examine each router’s routing tables. Do any of the four routers know any routes other than connected routes? Do any of the routers know any OSPF-learned routes? None of the routers have any OSPF routes. This is one of the reasons why the PC’s cant ping the other routers. Step 7. From each router, use the show ip ospf neighbor command to discover with which other routers each router has formed a neighbor relationship. List the router pairs that have formed any kind of neighbor relationship on the lines below. None of the routers have OSPf neighbor relationships with the other routers. Step 8. From each router, use the show ip ospf interface command to list the interfaces on which OSPF...

...IP Networking Assignment 1.1 Chapter 1 1. The TCP/IP networking model is a model of networking functions that are separated into different layers. Each layer performs a specific function that effects the layer above and below it. We use the TCP/IP model to troubleshoot a computer that is experiencing network issues. 2. There are seven different layers in an OSI model. Layer 1 (Physical layer): the physical characteristics of a computer such as connectors and pins. Layer 2 (Data Link): defines the internet protocols and the format of a header and trailer that allows devices to send and receive data successfully. Layer 3 (Network): routing IP packets and IP addressing. Layer 4 (Transport): data delivery from one computer to another. Layer 5 (Session): User communicating with the computer. Layer 6 (Presentation): defining data formats such as text files (.txt) and picture files (JPEG). Layer 7 (Application): support for applications such email and internet explorer. 3. The difference between same layer and adjacent layer interactions is that same layer deals with two computers, while adjacent with just one computer. 4. Encapsulation is the process of placing data into a header and footer. Decapsulation is the process of removing data from a header and footer. Chapter 2 1. There are five different types of Ethernet which are 10Base2, 10Base5, 10Base-T, 100Base-TX, and 1000Base-T. Also there are many different types of topologies such as bus, star, mesh, extended star...

...3 factors that could affect splicing performance: Cleaving is a major factor in splicing fiber optic cables, and it is necessary to use a good cleaver to do this with. Cleanliness is another factor that will affect splicing performance; the glass core must be cleaned prior to putting it in the connector because dust will play a factor in the performance of the splice. And using different brand of fiber cables can play a major factor in the overall performance of the splice. It can make it difficult to join the two cables together. The way to help reduce these factors is to ensure that you are using the proper splicing practices. (Fiber Optic Splicing) 3 intrinsic factors that can affect connection performance: Intrinsic factors are things that you cannot control during the splicing and connection process such as: Numerical Aperture mismatch, this is caused by the differences in the fiber itself and is nothing that you can control. Reflection loss is another factor that you cannot control because it is again based on the type of fiber optic cable you use for the splice. Refractive index profile distance is also a factor that is affects connection performance and it also caused by the cable manufacture and not something that you have done during the splicing process. The way to avoid all of this is to use the same type of fiber to do the splice if at all possible. (Intrinsic and Extrinsic factors) 3 extrinsic factors that affect connection performance: Extrinsic factors that...

...Abstract:-The fourth generation of mobile networks will truly turn the current mobile phone networks, in to end to end IP based networks, couple this with the arrival of IPv6, every device in the world will have a unique IP address, which will allow full IP based communications from a mobile device, right to the core of the internet, and back out again. If 4G is implemented correctly, it will truly harmonize global roaming, super high speed connectivity, and transparent end user performance on every mobile communications device in the world. 4G is set to deliver 100mbps to a roaming mobile device globally, and up to 1gbps to a stationary device. With this in mind, it allows for video conferencing, streaming picture perfect video and much more. It won’t be just the phone networks that need to evolve, the increased traffic load on the internet as a whole (imagine having 1 billion 100mb nodes attached to a network over night) will need to expand, with faster backbones and oceanic links requiring major upgrade. 4G won’t happen overnight, it is estimated that it will be implemented by 2012, and if done correctly, should takeoff rather quickly. 4G networks i.e. Next Generation Networks (NGNs) are becoming fast and very cost-effective solutions for those wanting an IP built high-speed data capacities in the mobile network. Some possible standards for the 4G system are 802.20, Wi-MAX (802.16), HSDPA, TDD UMTS, UMTS and future versions of UMTS. The design is that 4G will be based on OFDM...

...Title: EFFECTS OF E-COMMUNICATION ON CORPORATE ORGANIZATIONS CHAPTER 1 INTRODUCTION Electronic communication otherwise known as E-Communication is a type of communication carried out using electronic media. Such communications allow transmission of message or information using computer systems, fax machine, e-mail, tele and/or video conferencing and satellite network. People can easily share conversation, picture(s), image(s), sound, graphics, maps, interactive software and many other things. Due to electronic technology, jobs, working locations and cultures are changing and therefore people can easily get access to worldwide communication without any physical movement. Experts have defined electronic communication as the transmission of information using advanced techniques such as computer modems, facsimile machines, voice mail, electronic mail, teleconferencing, video cassettes, and private television networks.” 1.1 Background of the Study Communication is said to be the imparting or exchanging of information by speaking, writing, or using some other medium. It could be between two or more persons, human and machines or any other communicable entity. Group communication can be carried out through various means such as smoke signals and drums which was common in ancient Africa, America and parts of Asian, the fixed semaphore in ancient Europe and electronic means which is most prominent, popular and recent. This research details on the effects of communication...

...Hospital Networking Project (Week 3) University of Phoenix CMGT 554/IT INFRASTRUCTURE Patton-Fuller Community Hospital Networking Project Today most new building construction is built with new technology and is not as much concerned with the type of budgets that a hospital muse consider in order to redesign a whole new network structure for the purpose of being more optimal and maintaining standards that keep up with advances in new technology. In most cases, a hospital’s network can transition over time with new technology and evolve into meeting the demands it requires to perform effectively. However, upgrading a hospital’s entire network can often be very expensive to implement and sustain. There may be a case where components or parts are no longer being produced to meet current and future demands. In the last several years, changes in healthcare put a demand on hospitals to maintain their networks with new, more efficient solutions that can enhance performance, keep cost low, but most one that is reliable . The Network architecture at Patton-Fuller hospital was designed for each department to rely on information flow between each department. In other words, if the accounting department needed information from the pharmacy or admissions in order to create invoices or insurance billing, it would be rely on those departments to share real time information through the network. It is important for a facility as large as a hospital to have a Networking system that...
