Where Modern Meets Mundane: The History of the Internet in a Contemporary Culture If we are the so-called “networked society” (Kåhre, 2013, p.1), and this is the age of web culture, we have to ask ourselves if the Internet has indeed just recently jumped out of antiquity. Through a critical analysis of literature surrounding different communication types, I will endeavour to investigate which aspects of the Internet, if any, could be regarded as ‘new’. Throughout this essay, I use the word…

Transmission Control Protocol/Internet Protocol (TCP/IP) are a suite of protocols designed for large-scale internetworks that span LAN and WAN environments. TCP/IP are communication protocols that are used to handle traffic on the internet and other networks. The two most important protocols are the Transmission Control Protocol (TCP) and the Internet Protocol (IP). These are today the standard networking protocols and were created from a synthesis of a number of earlier developments in the…

Wire Rope Wire Rope Definition and Types Wire rope is machine composed of individual wires that have been twisted to form strands and work together to achieve optimum results for the selected operation. Strands are then twisted, to form a wire rope. The parts of a wire rope illustrated in the figure below. The core is the foundation of the rope design. The main functionality of the core is to support the wire stands and maintain them in their position during the lifecycle of the product…

Alejandro Carriegos 9/1/2015 Network Layer The main purpose of the network layer packet is connecting with the destination; it must be familiar with the topology subnet and choose the appropriate paths through it. When the source and destination are on different networks, the network layer (IP), have to deal with these differences. The services provided by the network layer should be independent of the topology subnet. The transport layer must be protected in the number, type, and topology of…

Task 1 ( P1) Explain how networks communicate. Wired: Used to transfer information over networks some include twisted pair cables, coaxial cables and telephone lines. Wireless: Are used when it is impossible or difficult to install wires or cables it is sends communication signal via microwaves, satellite, infrared signals and so on. Physical Layouts: Ring: Each computer is connected to two other forming a single continuous pathway for signals. Star: Consists of a central switch, hub or…

The following are the top 10 types of packets: IPv4: Internet Protocol version 4 (IPv4) is the standard version of the internet protocol, that acts as the platform for standard internet protocols and existing internet models (ISP). Extensive use of this protocol led to exhaustion of IP addresses. Therefore, we are bound to use IPv6, in the near future. A feature called as sub-netting is used for IP address allocation. It is defined in RFC 791. IPv6: Internet Protocol version 6 (IPv6) is the…

There are two major components to the MPLS architecture and they are control panel and data panel. The control panel has a complex function and is used to exchange the layer 3 routing information (RIP, OSPF, EIGRP, and IGRP) and labels (Label Distribution Protocol (LDP)). The data plane is used to forward the packets based on the destination address or labels. The routers that are capable of routing and switching in the MPLS domain are called LSR (Label Switch Routers). This routing and…

While ubiquitous Internet access is extremely convenient and enables marvelous new applications for mobile users, it also creates a major security vulnerability—by placing a passive receiver in the vicinity of the wireless transmitter, that receiver can obtain a copy of every packet that is transmitted! These packets can contain all kinds of sensitive information, including passwords, social security numbers, trade secrets, and private personal messages. A passive receiver that records a copy of…

ANSI 8. The TCP/IP and OSI models have some obvious differences, like the number of layers. Think about the more commonly used version of the TCP/IP model discussed in this chapter, and then think about how to talk about TCP/IP using OSI terms. Which of the following is a correctly phrased statement for how to use OSI terminology? a. HTTP is a Layer 5 protocol. b. IP is a network layer protocol. c. TCP is a Layer 2 protocol. d. Leased lines are Layer 7 standards. 10. Which…

1.10 FIREWELL: Firewall is a physical security device that cleaned in specs traffic coming from one network to a different network. A firewall is a system that implements an access control policy among two networks. Example: “Allows: http, mails etc. Keeps out: intruders, denial of services attacks etc.” 1.10.1 Firewall work: The protocol that computers use to be in touch on the internet is called TCP/IP. Each computer on the Internet has a only one of its kind internet protocol and…
