Advantages • Following are some major advantages of computer networks. • File Sharing • Computer network allows file sharing and remote file access. It is a method of distribution of digital stored information like multimedia, computer programs, documents, etc.
Cont… 2. Resource/Hardware Sharing Users can share devices such as printers, scanners, CD-ROM drives, hard drives etc. For example, 20 computers can be interconnected, using a network, and just with one modem and one printer can efficiently provide the services to all 20 members.
Cont… 3. Application sharing Applications can be shared over the network, and this allows to implement client/server applications 4. User communication Networks allow users to communicate using e-mail, newsgroups, and video conferencing etc.
Cont… 5. Network gaming Lot of games are available, which are supports multi-users. 6. Increased Storage Capacity A standalone computer might fall short of storage memory, but when many computers are on a network, memory of different computers can be used in such case. One can also design a storage server on the network in order to have a huge storage capacity.
Cont… 7.Increased Cost Efficiency There are many software available in the market which are costly and take time for installation. Computer networks resolve this issue as the software can be stored or installed on a server and can be used by the different workstations.
Disadvantages Following are some major disadvantages of computer networks 1. Security Issues One of the major downside of computer networks is the security issues involved:
Cont… If a computer is a standalone, physical access becomes necessary for any kind of data theft. If a computer is on a network, a computer hacker can get unauthorized access by using different tools.
Cont… In case of big organizations, various network security software are used to prevent the theft of any confidential and classified data.
Cont… 2. Rapid Spread of Computer Viruses If any computer system in a network gets affected by computer virus, there is a possible threat of other systems getting affected too.
Cont… Viruses get spread on a network easily because of the interconnectivity of workstations. Such spread can be dangerous if the computers have important database which can get corrupted by the virus.
Cont… 3. Expensive Set Up The initial set up cost of a computer network can be high depending on the number of computers to be connected. Additional devices like routers, switches, hubs, etc. can be very pricey
Cont… • Dependency on the Main File Server • In case the main File Server of a computer network breaks down, the system becomes useless. In case of big networks, the File Server should be a powerful computer, which often makes it expensive.
