TOPIC: File Sharing

Introduction

Computer files are the most basic unit of data that users can store on a disk. Every program, image, video, song, and document are stored as a file.

 

FILE SHARING: It is defined as public or private sharing of data in a network which cannot be accessed by everyone. File sharing allows a selected number of people to read, view or edit it.

TYPES OF FILE SHARING: Here are the most common ways of sharing and distributing files online

i.                File Transfer Protocol (FTP): The FTP is used for accessing or editing files among a number of users with a password making it impossible for an outsider to access the file. It is usually used by bankers.

ii.              Peer-to-peer networks (P2P network): Here you can share files without actually using the internet server

iii.            Removable storage media: This file sharing device removed or inserted in a computer for the purpose of sharing files stored in it. Examples: the use of flash drive, use of memory card, removable hard disk.

iv.             Online sharing service: Online sharing service is a web service that allows users to store or share data on the internet for personal or professional use. A member may upload photos, music or video online, the file sharing platform will allow others using same platform to download the files.

 

Risks Involved In File Sharing

i.   Downloading a file that may contain virus

ii.   Accidentally uploading of sensitive files in public, which can’t be retrieved when others download it to their phones.

iii.  Loss of privacy since a third-party whom the file is not meant for can access it through a friend.

 

Benefits of File Sharing:

i.     Easy assessment of desired piece of information

ii.   Saves time because you can easily retrieve the information from the group that shared the file, instead of surfing the internet and searching tirelessly for the piece of information.

iii.  Reduces storage space. Since the information still remains in the online group platform, it can be downloaded anytime you desire even if there is no space in your computer or smartphone.

The file management system manages the independent files and acts as the software interfaces between the user programs and file operations. Basic Operations of Computer Files 1.     Insertion: records must be inserted at the place dictated by the sequence of the keys. As   obvious, direct insertion into the main data file would   lead to frequent rebuilding of the file. This problem could be mitigated by reserving overflow areas in the file for insertions.
