Disadvantages and advantages of networks 9ice the first concoction of a nexus of computational processing power in the late 1960s, the practicality of networks been bought into question due to the advancements of on- j sse m b lage s excpfittat ingad/anta^eous intimations for the ever changing cycle of head way to modern day network. Providmgvaluable resources to organisations, innumerable technicians give leirtime to creating and perfecting a cornucopia of networks. The advantages of networks are prominent and numerous, and very well documented. So you might be asking yourself why there is debate over aspects of networks, from home networks up to large corporate networks. This is due to the widespread fear that networks are essentially never safe, due to the interlacing of computers providing an ideal environment for viruses which are go -g to exploit a security loophole to contaminate multiple computers, which ultimately prevails tohigh costs for companies. Once cne computer in a network is nfected,the vruscan competently let itself in to other computers on the network; it only takes one computer linked to yours to infect you. this has led to concerns over tne security of organisations having a system which can betaken down with just one f le. However, networks are frequently used without such problems, as mu tifarious companies never get infected due to the right hardware and software, infections can be avoided as firewalls are go ng*.o block unwanted access. However, the cardinal advantage of networking is transferring files t o other computers on the network. This is beneficial to companies where manual file sharing has r u n its course and become impractical to maintair, due to the amount of time it takes for files to get .non n :i employees. In addition to this, many people can access a particular database at a single time arid update it simultaneously, which keeps it up-to-date. Usinga network based database, users can deser the system while another user maintains the system, a process made significantly harder if using standalone computers, so users are more free time to spare time they would probably had if using individual databases. Multiple users can also track changes on documents, the shared drive to access the same file other users have open. This is particularly useful where people working in different locations can work on the same document and whichare updated in realtime ove' wan. similarly, you can make files read orly, so stop other people making :hanges, while allowing them to view the file easily. Userscan for technical nelpto, using simple IM protocols over a network. Another advantage of networks is the abiity to share resources; expersive printers would never be given to incividual employees of a company, but with networking, that one laser printer is go y/.o be shared among dozenscf users, decreasing overall costs and counteracting the costly sum to set jp the network. This initial sum increases as the size of the network increases, but users often say that it is well worth the cost, as the advanced technology essentially means users can say goodi ye to transferring external memory and cross over into a system where file sharing speeds nevei decrease so long as it is maintained, and due to the nature of networking solutions, always go g o see new advancements in technology. In a system of standalone computers, all f les are saved on individual hard drives, and have i transferred to new devices if the computersare upgraded. But in networks, the file server can new computer everything tiat was saved on their user account, which ultimately means that ? file transferís not needed. The belief that documents are saved on local hard drives is a •software common to all computers on the networkis saved on the drive; both software • operating system need to ke saved locally to ensure computers run at a reasonable speed. ; can be removed for repair easily due to the network, as the file server ensures that I other users can still accessfiles easily. Great Britain has recently begun to understand the problems facing government networks; wo vo invested £500million into upgrading the security of defen:e networks, which iscurrenty known to be susceptible to cyber attacks. This is a major disadvantage of large, private networks, as each security measu'e has to be addressed to avoid a catastrophe, costing money which could go to nthor rauses. Security issues are commonly investigated by a third party, who'‘hack" the network for the network owner, establish the problems efficiently, and cuickly patch any security loopholes, so the network is no: susceptible tc any viruses, backdoor Trojans and other security problems for a longtime as hacking technology ad/ances faster tian the network security. Ultimately, the risk of your network being hacked decreases if network security is updated regularly, while the network iheait's kept protected consistently provided it is Lp-to-date. However, this process is known to have been expensive, which adds more costs to the network. While internet connections can be established through individual routers, users are often achingl but; ■ taster speeds, and networks using a router and dedicated line provide these fast speeds; the cost of setting this up is high. However, if you a part of an onlmecompany, it is likely to recuperate these costs with faster speeds, increasing income; websites whichare 'for users is jnlikely to profit, and cannot work well with other companies. Networksthat r from faster broadband speeds are therefore likely to profit less. File networks accessed by multiple users can easily establish variegating levels of privileges users, which means that certain groups of users can only gain access to what the admins needaccessto, preventing privacy issues of users backhgdata up one external hard drives, that higher level users, such as CEOs, can access employee files where needed, to look documents in cases of suspicious activity in the workplace. Worldwide, :ompanies are aware of the possibilities of network, and the security proolems. Wo as users of these networks also understand the consequences of getting vi'uses on networks, as both security and common sense a'e needed to a/oid security b'eaches. Modern companies also know the advancements of present networking technology, anc how this upcoming technology is what ’; going to define the way organisations work in the future. Many networks have also already been subject to security problems, and it's due to these problems that security on other networks is go gto advance, while also becomingcheaperforsmaller businesses. Advancement is yet going on . and networks wi I one day be accessible for all to create.
