Alternatives of Network File System Since human beings have used Computers , the request of being rich ,and getting more information quicker than before has increased . Have you ever found yourself rushing from one computer to another in your office or home ,attending to several different jobs at various location? Or do you often find yourself moving files that need printing from a PC that you happen to be working on the PC that is Connected to the printer ? You may have heard a lot about the advantages of using the internet for sending e-mail, and decided that you want to get connected . Or perhaps you are already connected to the internet through a single PC/Modem , but want all of your office colleagues to have access . All of these situations can be made easier by allowing the various machines to communicate with each other – by networking the PCs but sometime you don’t know that your PC has (NFS) operating system for sharing file systems and directories across TCP/IP - based Networks. Network File System (NFS) is a popular network operating system and it’s a distributed file system that allows users to access files and directories located on remote Computers and treat those files and directories as if they were local. For example, users can use operating system commands to create, remove, read write and set files attributes for remotes files and directories. NFS was first introduced by Sun Microsystems in the early 1980s and was quickly adopted as de facto standard for sharing files and printers between UNIX system. This standard was extended to include PCs and became the basis for must transparent file and print connectivity software solutions .

But In this proposed model, we logically group the roles instead of hosts and storage devices. Roles are assigned to hosts. There are many-to-many relationship between roles and hosts. Multiple hosts may have a single role and multiple roles may be assigned to a single host. The relationship between roles and the storage is also many-to-many. The specific access rights are associated with each role to access the storage.
Communication within our network has much improved with Windows NT. We are now capable of sharing files and data between all offices. Our Fast Ethernet Intranet provides speedy and stable communication transport.

File servers are an important part of any business. The file server is the central location of files for a business small or big. The file server can be a cloud accessible server which grants accesses anywhere. The file server can also be a dedicated server which is only used on the business network. I am going to touch on the specifications of a file server. This means I am going to go over CPU, memory, bus, DMA, storage, interrupts, input/output peripherals, and monitors of a files server.
Peer-to-peer is a communications model in which each party has the same capabilities and either party can initiate a communication session. Other models with which it might be contrasted include the client/server model and the master/slave model. In some cases, peer-to-peer communications is implemented by giving each communication node both server and client capabilities. In recent usage, peer-to-peer has come to describe applications in which users can use the Internet to exchange files with each other directly or through a mediating server.
Linux has long been one of many operating systems that have been out to prove its worth in all types of environment. It is currently being considered for enterprise network purposes as well as data centers where it implies servers, workstations and any mainframes as needed. Choosing what operating system to use, whether it is open source or not, can be difficult, though. This paper projects the advantages and concerns of choosing an open source solution like Linux as administrators and users are becoming more aware of Linux running on both server and desktop systems. It is quickly being adopted in an ever increasing number of global corporations and government agencies.
E-mail has become an indispensable tool for communication. It is rapidly becoming the most popular form of communication. With Windows NT, you will have to buy a separate software package in order to set up an e-mail server. Many NT-based companies use Microsoft Exchange as they¡¦re mailing service. It is a nice tool, but an expensive solution with not such great success in the enterprise environment. Microsoft Exchange Server Enterprise Edition with 25 Client Access Licenses costs $3,549.
Sadly, many people refuse to face the onslaught of computer technology. A 1994 survey conducted by Dell Computers indicated the 55% of Americans are phobic or resistant to computers (Column). In addition, many important people, including CEOÕs of major companies, are rumored to be computer illiterate (Column). The former CEO of IBM even admitted to never using a computer (Column). Fortunately, PC’s are becoming more and more user friendly as the technology improves. Fewer errors, less maintenance and quicker functioning should encourage many reluctant people to finally step into the new era.
Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.
The computer evolution has been an amazing one. There have been astonishing achievements in the computer industry, which dates back almost 2000 years. The earliest existence of the computer dates back to the first century, but the electronic computer has only been around for over a half-century. Throughout the last 40 years computers have changed drastically. They have greatly impacted the American lifestyle. A computer can be found in nearly every business and one out of every two households (Hall, 156). Our Society relies critically on computers for almost all of their daily operations and processes. Only once in a lifetime will a new invention like the computer come about.
Electronic Mail, a means of communication that is growing at a very rapid rate. In this paper, I will write about introduction of e-mail, the advantage and disadvantage of e-mail, mailing lists, sending an e-mail message, sending attachments, e-mail improvement, and security features. Introduction of Electronic Mail Electronic mail (E-mail) has become popular and easy way of communication in this decade. E-mail is a method of sending and receiving document or message from one person to another. E-mail is not only replacement for postal mail and telephones, and also it is a new medium. E-mail send plain text, images, audio, spreadsheets, computer programs can attach to an e-mail message. Using the e-mail, you must have a computer on a network. The computer must require a modem and phone line. Sending and receiving e-mail needs an e-mail program. Every e-mail user requires an e-mail address. This e-mail address is similar to a postal address. E-mail address is written as username@domain, for instance, PCLEE@juno.com. The username is used for sending and receiving e-mail.
Another good point about the Internet is that it provides e-mail.
Networking is another way that advances in computer engineering and software has paved a way for the advancement of communication, industry, and our lives in general through technological advancements. Just as the utilization of fire and carving of the wheel gave us advantages over the perils of life, the networking of computers has brought an unreachable far off world closer to each and every one of us. First and foremost we are now able to nearly instantaneously share information with an unreachable world. The engineering that made this possible began not on some other planet, or from the depths of a holy shrine. But from the ingenuity of a partnership of companies that sought to find a reasonable (and soon profitable) solution to the proprietary incompatibility of emerging information system networks.
Computers are forever present in the workplace. Word processors-computer software packages that simplify the creational and modification of documents-have largely replaced the typewriter. Electronic mail has made it easy to send messages worldwide via computer communication networks. Office automation has become the term for linking workstations, printers, database system, and other tools by means of a local-area network. An eventual goal of office automation has been termed the 'paperless office.' Although such changes ultimately make office work much more efficient, they have not been without cost in terms of purchasing and frequently upgrading the necessary hardware and software and of training workers to use the new technology.
Email (electronic mail) was one of the biggest breakthroughs in communication when the internet was commercialized. With email, it became possible to send messages and letters across the world in a matter of seconds to the recipients address. Email was used as an alternative to conventional mail or snail' mail, as the term was introduced to describe its speed. As technology improved, it became possible to attach' documents, photographs and even sound clips or songs to emails which made mail by post redundant. Emails used packet switching software whereby the email was broken down into packets' and sent via the internet to the recipient.
