Advantages And Disadvantages Of Remote Working System Computer Science Essay

Advantages And Disadvantages Of Remote Working System Computer Science actIntroductionThe following report depart be based on providing potential requirements of the basic scenario and a through explanation of advantages and disadvantages of updating the up-to-date meshing of the EERP Comp some(prenominal). By analysing the key requirements it is clearly explained that the EERP is having two major employee classes as senior provide and junior staff.Junior staff works in the occasion which mean that they worked on fixed places. This impart result them to project personal computers with LAN (Local Area Network) connectivity. Depending on the budget this endure deepen up to a piano tuner net income by go throughing wire little interfacing clear up to their personal computers and having WIFI z mavins on the working bea. fourth-year staff on the other hand, they work in their homes. From their they should be able to do dissimilar kind of functionalities E.g. deliver co mpanys message via ProwerPoint presentations, compile, print registers, coiffe quires on brisk customer records, send and receive email and complete sales orders. These functionalities should be done online or through the WIFI earnings at the company. It is minute that the management has decided to equip the senior staff with a change of wireless enabled portable notebook PCs, printers and Personal Digital Assistants (PDAs) to get the maximal benefits out of their senior staff.To achieve these desired functionalities it is a mustiness to implement a Virtual Private Network (VPN) betwixt the senior staff and the Office network of the office. This will result them to connect their office even up though they are remotely committed. They will be able to perform same kind of functionality which they perform in their office environment. When they work in the office they can connect to the WIFI network without connecting to the VPN. This network architecture will provide the sen ior member to be connected on their office network every time whenever they want.When it comes to wireless connectivity or VPN, earnest is a must. It is important to implement necessary guarantor methods and protocols to connect any of the networks. With respect to the following requirements no of WIFI and VPN users should me defined and should be expansive with the growth of the company. Depending on the budget, suitable VPN provider should be selected.With the basic sagacity of the key requirements it will be possible to prepare a network system with remote networking functionality.Advantages and Disadvantages of having remote working systemPros,It will be easier to implement and maintain.High reliability and availability.Network cabling will be reduced.Employees can stand on their work place dynamic every last(predicate)y without staying on one locationCan tardily tack the security of the network.Can easily divide departments as blocks of network access points.Expansion of the network will be easier than a Traditional wired LAN.Cons,Network connectivity will be lower than a wired LAN.VPN implementation will be expensive. gild should be facing a higher security threat when implementing a VPN.In order to enhance the security, firewalls and other third party tools need to be purchased.Employees should be well trained to use VPNs and wireless networks to overturn any sort of interruptions.Failure of a VPN will result some employees to not to cooperate with the company until it is fixed.Benefits to the companyThis system will lay off employees to work interactively without any disruption. Employees who work on the office will set out the WIFI connectivity. This means that they can work on their office desk as well as when they are not. They might be interacting with the customers even so they can connect with the network. They can share information, print documents and can inquiry the information informationbase. This will result interactive and eff icient communication with their customers.Senior staff on the other hand can work in home as they are in the office. Because of the VPN they will gain virtually all of the network capabilities as they are in the office. Email services, document sharing, print documents and even online presentation facilities can be provided. When they visit the office they can connect to the wireless network use their wireless enabled notebooks and PDAs. As a result they can turn over almost the same functionalities. gauge of the costNETWORK CABLE BULK CABLE 1000M UNSHIELDED misrepresented PAIR (UTP) = 315RJ45 conjoinor Network Cable CAT5 Crimp Ends Plug x 100 = 4.98D-Link DES-1024D 24-Port 10/100Mbps Network Switch = 61.00D-Link DSL-2640R radiocommunication G ADSL2 wireless router DSL 802.11b/g = 56.00NETGEAR ProSafe Quad WAN Gigabit SSL VPN Firewall SRX5308 Router = 254.00RJ45 Network Crimp cock = 20.00Mercury Multi Network Tester = 7.00Test UM WP150 Wi Net Window Wireless Anal yzer = 150.00Task 2.Set up a network with 2 wireless nodes and 1 wired node.192.168.248.57 - omission Gate steeringCUserssonyDesktopNWinternet.jpgCUserssonyDesktopNWwifi signalCUserssonyDesktopNWLinksys-router-wireless.jpgCUserssonyDesktopNWlaptop.jpg192.168.248.61CUserssonyDesktopNWpc.jpgCUserssonyDesktopNWwifi signalCUserssonyDesktopNWlaptop.jpg192.168.248.62192.168.248.63Wireless RouterA router is a device that forwards selective information packets along networks. A router is connected to at least two networks, commonly two LANs or WANs or a LAN and its ISPs network. Routers are located at openings, the places where two or more networks connect, and are the critical device that keeps data flowing between networks and keeps the networks connected to the Internet.When data is sent between locations on one network or from one network to a second network the data is always seen and directed to the correct location by the router. The router accomplishes this by utilize headers and forwarding tables to determine the surmount path for forwarding the data packets, and they alike use protocols such as ICMP to communicate with each other and configure the best route between any two hosts.Network Interfacing greenbackA network interface twit, more commonly referred to as a NIC, is a device that allows computers to be joined together in a LAN, or local area network. Networked computers communicate with each other using a given protocol or agreed-upon language for transmitting data packets between the divergent machines, known as nodes. The network interface card acts as the liaison for the machine to both send and receive data on the LAN.The most common language or protocol for LANs is Ethernet, sometimes referred to as IEEE 802.3. A lesser-used protocol is particular Ring. When building a LAN, a network interface card must be installed in each computer on the network and all NICs in the network must be of the same architecture. For example, all must either be Ethernet cards, Token Ring cards, or an alternate technology.WIFI CardsA wireless network adapter allows a computing device to join a wireless LAN. Wireless network adapters contain a built-in radio transmitter and receiver. Each adapter supports one or more of the 802.11a, 802.11b, or 802.11g Wi-Fi steps.Wireless network adapters also exist in several different form factors. Traditional PCIwireless adapters are add-in cards designed for installation in spite of expectance a desktop computer having a PCI bus. USB wireless adapters connect to the external USB port of a computer. Finally, so-called PC Card or PCMCIA wireless adapters insert into a narrow open bay on a notebook computer.One example of a PC Card wireless adapter, the Linksys WPC54G (compare prices) is drawn above. Each type of wireless network adapter is small, generally less than 6 inches (0.15 m) long. Each provides equivalent wireless capability according to the Wi-Fi standard it supports.Some notebook computer s are now manufactured with bulit-in wireless networking. infinitesimal chips inside the computer provide the equivalent functions of a network adapter. These computers on the face of it do not require separate installation of a separate wireless network adapter.Setting up wireless ConnectivityI have used TP_LINK as the router.
