Development in System Networks

What is a Network?

Communication and information are the two most important concerns for an organization. Today¡¦s organizations use a number of computers and communication tools (telephone, faxes, internet) to help them function in their daily operations. Communication is crucial among departments, and information and data throughout the organization needs to be easily accessed in order to allow for a steady workflow. To overcome these obstacles, computer networks are necessary. Computer networks allow the user to access programs and databases, and it provides communication possibilities faster than other methods.

Networks allow the connection of computers and printers so that resources can be shared. The technique that is most commonly used to link computers together include peer-to-peer and client/server. Peer-to-peer networks contain no central server. It basically contains a set of computers connected together through cabling. Although each computer is able to share the files and peripherals of the other computers connected to the network, application programs are not shared. This type of network is most commonly used for less than a dozen computers.

Although a peer-to-peer network may be simple, there are a couple of disadvantages to it. If one user on the network turns off their computer their information or peripherals will no longer be available for others to share. In addition, accessing data and applications from another person's computer can cause performance problems for that user.

On the other hand, client/server networks provide more flexibility than peer-to-peer networks. This is the fastest and most expensive of the two. In this setup one computer is designated as ...

Wireless networks are becoming so popular today that the technology is evident in hand held devices, which allows access to the internet, mobile two way pagers, which gives users email capabilities, and the list can extend even further. In the end, all of the types of networks serve one purpose; to allow easier accessibility to information.

  • The Impact of the Internet on Society

    The Internet is, quite literally, a network of networks. It is comprised of ten thousands of interconnected networks spanning the globe. The computers that form the Internet range from huge mainframes in research establishments to modest PCs in people's homes and offices. Despite the recent hype, the Internet is not a new phenomenon. Its roots lie in a collection of computers that were linked together in the 1970s to form the US Department of Defense's communications systems. Fearing the consequences of nuclear attack, there was no central computer holding vast amounts of data, rather the information was dispersed across thousands of machines. A set of rules, of protocols, known as TCP/IP was developed to allow disparate devices to work together. The original network has long since been upgraded and expanded and TCP/IP is now a "de facto" standard.

    Each computer setup is unique with certain strengths and weaknesses. The network takes advantage of the strengths of each individual computer and makes them available to all users. A network essentially expands the capabilities of each computer by increasing functionality thru resource sharing. In the house, there are a total of four computers and two laptops. Processing speed and an abundance of ram is not essential for a server with such low traffic. Thus the most antiquated computer was elected for this function. Between all the computers, we have several extra pieces of hardware such as a zip drive, CDRW, DVD ROM, scanner, and multiple printers. Each piece of hardware is dispersed between the computers.

    A network computer or data network is a telecommunications network that allows computers to exchange data. In computer networks, networked computing devices transmit data to each other using data connections. These connections are established with nodes using either cable or through wireless media. The most famous and interesting computer network is the internet network. There are many types of computer networks, local area networks (LANs) to wide area networks (WAN) campus area networks ( containers ) metropolitan area network MAN ) and home area networks (HANs). With massive uprising in pc’s in the early eighties, the LAN system expanded rapidly. The LAN system on a workstation can be functioned via a short networking cable. LANs consist of computer units linked to a control computer called server. Network technology is the way by which the numerous stations are linked with one another. LAN can be linked to greater networks including mainframe. This provides LAN users with the access to enormous computing power and excellent communication facilities. Computerization in the banking system is the best example of the network LAN.

  • What´s a Peer-to-peer Network?

    1225 Words  | 3 Pages

    Peer-to-peer (P2P) is a substitute network design to the conventional client-server architecture. P2P networks utilize a decentralised model in which each system, act as a peer, and serve as a client with its own layer of server functionality. A companion plays the role of a client and a server in the meantime. That is, the node can send calls to other nodes, and at the same time respond to approaching calls from other companions in the system. It is different from the traditional client-server model where a client can just send requests to a server and then wait for the server’s response.
