    Study Notes

    Network Operating Systems

    • Two main types of networking models: Peer-to-Peer (P2P) and Client-Server.

    Peer-to-Peer Networking

    • P2P networks consist of connected PCs that share resources directly without a separate server.
    • Can be ad hoc (temporary connections) or permanent (set up in small offices).
    • Appropriate for small local area networks (LANs), especially in homes and small businesses.
    • Utilizes the same protocols and software across all devices.
    • Can take advantage of the internet for geographically dispersed networks.
    • Hybrid configurations exist, where routers serve centralized functions while peer devices manage local sharing directly.

    Client-Server Networking

    • Gained popularity in the 1990s, allowing personal computers to replace mainframes.
    • Involves specific roles for client devices (requesting info) and servers (providing data/resources).
    • Common on both the internet and local area networks (LANs).
    • Examples of client-server systems include web browsers, web servers, and DNS systems.

    Client Server Hardware

    • Client devices include PCs and mobile devices with network software for requesting data.
    • Servers are powerful machines capable of storing files, applications, and databases, typically with enhanced processing and memory capabilities.

    Client-Server Applications

    • Organize network traffic by sending messages from clients to servers for processing and response.
    • A single server can serve multiple clients, and server pools can handle increased loads.
    • Some devices may function as both clients and servers for different applications.

    Local Client-Server Networks

    • Many home networks operate on a small-scale client-server basis.
    • Broadband routers serve as DHCP servers, assigning IP addresses to connected devices.
    • Other server types in homes may include print servers and backup servers.

    Client-Server vs. Peer-to-Peer

    • Developed to efficiently share database access among multiple users.
    • Offers greater flexibility than mainframe models by allowing on-demand connections.

    Microsoft Windows Server Features

    • Windows Server OS provides enterprise-level operational control over data storage and networks.
    • Roles assigned to a server determine its function (e.g., file server, DNS server) with additional features enhancing its capabilities.

    Active Directory

    • A directory service within Windows Server, essential for managing permissions and network resource access.
    • Organizes data as objects (users, groups, devices).
    • Central to a Microsoft network, providing a Domain Controller (DC) for authentication.

    Domain Name System (DNS)

    • A set of protocols integral to TCP/IP for mapping computer names to IP addresses.
    • Facilitates communication between users and machines by resolving names.

    Organizational Units (OU)

    • Containers in Active Directory that hold users, groups, and computers.
    • Serve as the smallest organizational unit for applying policies and permissions.
    • Must maintain unique attributes for all contents within the OU.

    Active Directory Groups

    • Utilize groups to manage resource permissions, improving administrative efficiency.
    • Best practices include grouping users and applying access controls through these groups.

    Active Directory Users and Computers (ADUC)

    • A management console for administering Active Directory, allowing easy management of users, OUs, and attributes.
    • Highly utilized tool since Windows 2000 for effective Active Directory administration.
