File System Windows Filesystems In a computer, a file system (sometimes written filesystem) is the way in which files are named and where they are placed logically for storage and retrieval. The DOS, Windows, OS/2, Macintosh, and UNIX-based operating systems all have file systems in which files are placed somewhere in a hierarchical (tree) structure. A file is placed in a directory (folder in Windows) or subdirectory at the desired place in the tree structure. File systems specify conventions for naming files. These conventions include the maximum number of characters in a name, which characters can be used, and, in some systems, how long the file name suffix can be. A file system also includes a format for specifying the path to a file through the structure of directories. Windows 2000 systems can support the following file systems: FAT, FAT32 NTFS - New Technology File System CDFS - Compact Disk File System UDF - Universal Disk Format for DVDs. EFS - Encrypting File Sys
A local area network (LAN) supplies networking capability to a group of computers in close proximity to each other, like in an office building, school, or home. LANs are usually built to enable the sharing of resources and services like files, printers, games, applications, email, or internet access. Multiple local networks may stand alone, disconnected from any other network, or might connect to other LANs or a WAN (like the internet). Traditional home networks are individual LANs but it is possible to have multiple LANs within a home, like if a guest network is set up. Technologies Used to Build a LAN Modern local area networks predominantly use either Wi-Fi or Ethernet to connect their devices together. A traditional Wi-Fi LAN operates one or more wireless access points that devices within signal range connect to. These access points in turn manage network traffic flowing to and from the local devices and can also interface the local network with outside networ
