Identify hardware and software needed to secure your choice of networks against all electronic threats.

Efficiently resolved an Agency wide issue. Due to lack of compatibility with Windows 7 I had to find a fix for an issue that prevented user from working on their everyday task.

Compare and contrast the characteristics and the purposes of peer to peer LANs and client/server LANs.

The www.e-tutes.com networking basics tutorial teaches the history of networking, starting with the invention of the telegraph, and takes us through to the current communication environment of the internet. In addition, the tutorial teaches us the basics of what defines a network, the components required for a network, and the different types of topologies of networks. Furthermore, there are eight sections, which go into more detail on all of these areas, including different cabling and transmission protocols.

Networking is required to make accessible communication between computers possible by a network connection. Networking allows for many possibilities, such as accessing the internet, file sharing, file transferring and system communication. Throughout this assignment I will be attempting to provide information to facilitate the introduction of a new computer network linking all of IT&D’s premises.

Another fact to consider in implementing a network system it is the network protocol that we are going to use .

In a WAN, computers are connected together through further distances by telephone lines or radio waves. A WAN consists of at least two LANs. The largest WAN is the Internet. A disadvantage to a WAN is that message transmission may be delayed, lost, or damaged. Messages are passed from one computer to another until it arrives at the destination. Effective routing techniques are important to network performance. A single message may travel by different routes and arrive at the destination out of order. Typical transmission speeds range from 56 Kbps to 1.54 Mbps.

Nowadays everybody can get access to the internet through networks, but according to Columbia University over the 37% of people do not know what a network is. A network is a group of computers which are connected to share information, files, and performs tasks. A network is built using the same common language. My purpose of this project is to explain what a network is, and let you know how important is to know it. The next paragraphs will explain the introduction of networking, the disadvantages of networking, and the disadvantages.

Data is sent from one node to another simultaneously to all other nodes in the work

In today world LAN plays a major and mutual role for mid to large sized businesses to share data to common devices and its

Local Area Network or LAN is nothing but local setup for interconnection between two or more number of computers and peripheral devices. Devices like printer, desktop, laptops, plotters, scanners and faxes. LAN is limited area access network around one kilometre range such as office- building, home, laboratory, schools using network media. Today’s

The major characteristics of LANs, include their higher data transfer rates, smaller geographic range, and no need for leased telecommunication lines. Current Ethernet or other IEEE 802.3 LAN technologies operate at speeds up to 10Gb. This is the data transfer rate. IEEE has projects investigating the standardization of 40 and 100Gb.

The figure in appendix shows the basic physical layout of a LAN. As illustrated, a LAN contains various data equipment that all need to communicate with each other. A data equipment could be a web server, a printer or a database. Each data equipment constitutes the users of the LAN. The communication between each device is accomplished by sharing a common Transmission Medium. The Transmission Medium is typically some type of cable. This cable provides transmit and receive capability and all needed intelligence. Knowing the physical structure helps us to better understand the potential requirements when designing a LAN.

Computer network came into existence as a means of extending interoperability and promoting self-productivity through sharing of computer resources among the users. The trending factor in our society today is the fact that the world is connected as one global village. Humans are now able to connect together from any two points in the world. This is made possible by advances in telecommunication. Telecommunications simply is the extension of communication over a distance. This also brings about what we know as networking which is the interconnection of various equipment that are for the purpose of information sharing. Admittedly, long-distance networking haul is being achieved using fibre optics and microwave transmission for network bridges, this is commonly addressed as WAN – Wide Area Network. However, in interconnecting with our colleagues and equipment around us, we use the various form of LAN – Local Area Network, SOHO – Small Office Home Office falls to this category albeit via wireless transmission with the use of Access Points or wired technology using the Ethernet standards.

In a LAN, terminals can be connected to a central terminal (i.e. computer) that may act as the means for the particular network to achieve external intercommunication as well. In such case, a LAN of a certain building A can be interconnected to the LAN of a certain building B through a local area network-to-local area network infrastructure. Such interconnection is highly useful and significant when in need to save cost by sharing a printer, for example, between departments that would need, otherwise, separate printing devices (Kuross & Ross, 2005, p.34).
