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…

TCP/IP Model - TCP and IP stand for Transmission Control Protocol and Internet Protocol this network model has only four layers these are the application layer, the transport layer, the internet layer and the network access layer. These two protocols are used on the internet all the time for transporting data to allow communication to others on the internet and so on with TCP/IP instead of having separate layers for the presentation layer and the session…

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 each computer has a run of ports used to be in touch with other computers “Ex: http (web pages) – port 80 FTP (file) – port 21” 1.10.2 Need of firewall: We…

mini case Big E. Banking (BEB) discusses the problems with connecting networks together over a wide area, all using different protocols to communicate. The second mini case addresses the problems with software acquisition including the methods used to communicate across different software products. The third mini case investigates the types of networks and network protocols used by the fictitious company Atlas Advertising. Each mini case will addresses the problems stated above including a set…

controlled, the Internet is decentralized by design. Each Internet computer, called a host, is independent. Its operators can choose which Internet services to use and which local services to make available to the global Internet community. Remarkably, this anarchy by design works exceedingly well. There are a variety of ways to access the Internet. Most online services, such as America Online, offer access to some Internet services. It is also possible to gain access through a commercial…

perhaps the minuet – evoke orchestral style, but the remainder are intimate and highly expressive. The overture is of the same type found in the orchestral suites of Bach. Such movements are usually regarded as consisting of a slow dotted section followed by a fugue, but many can also be viewed as sort of binary form. Often the second half is, as here, a fugue in concerto style having little in common…

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…

STANDARDS AND PROTOCOLS There are many types of wireless networks available. This includes: WAN, LAN, MAN, PAN, WLAN. Below, I will go into detail about each type that will help you understand exactly what each type of network is and what it consists of. What is WAN? WAN or also known as a Wide Area Network is a network that consists of many Networks that are a part of other LAN networks that swaps data between one another across a wide area. The best example would be the Internet as this is a…
