Computer Networking is the connection of two or more computers that allows them to share resources. It can be done between computers in a home, a business, through a company, and also internationally. It may also be defined as a method of connecting two or more computer systems together including printers and other peripherals.
The advantages of a network are significant, even on a network of only three systems. In computer networks, there has never been a truer statement that this is a case of advantages experienced being far superior to the sum of the parts. PC networking is, therefore, a rapidly evolving discipline with many exciting opportunities. Challenges that arise in the network and in particular on the Internet tend to be truly global and have the potential to have an impact on millions of users.
A huge and growing impact is Internet shopping. Online shopping has grown over the past 10 years to become a huge market, and if a sales business does not today incorporate this use of technology will fall behind their competitors.
But computer networking is also producing much more subtle uses within our societies. For example, Internet technologies can be implemented to affect favorably empathic response in those who have offended against Community rules by a lack of appreciation for the effects that their criminal behavior has on other people. In other words, the devices connected to the Internet can monitor at home prisoners to maintain their behavior, so that 20 years ago were not even entered the heads of science fiction writers, for the benefit of society as a whole.
The wireless Internet technology, is the development, also known as Wi-Fi, which is really taking the way people access Internet and has become widely popular in a short span of time. One reason for this is that it allows people to access the Internet through a network of hot spots, while traveling without the use of cables or wires. In short, it frees us from the tyranny of wires and plugs!
Wireless networks are now widely used including Internet-enabled cell phones with cell phone networks and, within buildings, wireless networks such as Bluetooth. These are in addition to the site networks used by academic institutions and large companies. The wireless router must be configured immediately for security right after setting the network. It 'important to note that wireless can easily also mean insecure unless users are careful to set the systems properly.
So, do it right away, as soon as you have the device running. You must set a new password for the router and limit access to only those computers on the wireless network.
of Informally defined computer networks is the Internet's foundation. The Internet itself is easier to understand when defined as the set of users, enterprises and content providers that are interconnected by the Internet Service Provider (ISP).
From an engineering point of view, and I beg you to forgive me for being somewhat techie here; Internet is the set of subnets, and aggregates of subnets, which share the address space and the exchange of information recorded IP reachability of those IP addresses using the Border Gateway Protocol. Computer networks can also be classified according to the network layer in which they operate according to some basic reference models that are considered industry standards, such as the reference model OSI seven-layer and five-layer model TCP / IP .
The companies that use their computer networks must administer complex systems that, once deployed, they become essential tools for the continuous efficiency of their operations. They employ administrators who focus primarily on the day-to-day operation of the networks, while network engineers deal primarily with system upgrades, security testing, and so on.
Given the high-tech nature of computer networks you would have thought that just maintaining and developing these would be tough enough. However, companies also routinely face ongoing challenges with the fight against malicious software, such as malware such as worms, viruses and spyware.
computer network has enabled people to work on the move, and take the job at home much more efficient than it has ever been possible before . today's mobile work force to connect several devices to the corporate network that are difficult to control by the security policy perspective. It is a common thread that companies that maximize the use of and benefits from the skills and capabilities of their networks are able to collect, analyze and disseminate critical marketing information quickly, which can give them an edge over their competitors.
However, data loss and system downtime can bring any business to it's knees, so in this area to use the strictly economic systems and labor, can be a false economy of the first order. There are many highly qualified personnel participating in courses and qualification of Microsoft Certified computer networking. These specialists are able to protect the corporate network day and night. They provide network support services that include data security, data backup and disaster recovery plans.
