    Study Notes

    Evolution of Computer Networks

    • Introduction of the first PC local area network (LAN) was ShareNet by Novell, which had both hardware and software components
    • Simple LANs in the 1980s were rudimentary and could only cover a single floor of the office, supporting no more than 30 computers
    • LANs initially had limitations such as file locking, but now support multiple users accessing programs or files concurrently
    • Wide area networks (WANs) emerged in the late 1980s, expanding to cover large geographical areas and supporting thousands of users
    • WANs can span buildings, states, countries, and continental boundaries, unlike LANs which are limited to single buildings
    • Personal area networks (PANs) are commonly associated with Bluetooth technology, but can also be created with other technologies such as infrared
    • The Bluetooth Special Interest Group (SIG) was formed in 1998 to unify computing, mobile communications, and the auto industry
    • Bluetooth networks are formed on an ad hoc basis, creating a dynamically created network called a piconet, allowing communication between devices without a central communication point
    • Metropolitan area networks (MANs) span a city or large campus and are managed by a central IT organization, while WANs involve publicly available communication lines and service providers
    • Wireless mesh networks (WMNs) have multiple redundant connections and are commonly accessed through wireless access points (WAPs)
    • WAPs may connect wirelessly to another connectivity device, such as a wireless router, or use a wired connection to a router or switch
    • Mesh network topology is characterized by multiple redundant connections, providing reliability and coverage across a wide area

    Wireless Mesh Networks and Network Components

    • Wireless mesh networks (WMN) use redundant connections to ensure smooth communication
    • WMN infrastructure requires support from access points and other wireless infrastructure
    • WMN is managed through a cloud-based network controller for remote administration
    • A+ exam 220-1001 objective 2.7 covers Internet connection types, detailed in Chapter 8
    • Primary network components include servers, clients/workstations, and resources
    • Every network requires a network operating system and a shared medium for connectivity
    • LANs and WANs were historically differentiated by connection speeds, but today geographical distance is the common classification
    • Servers are crucial for centralizing control of resources and security in a network
    • Servers can perform various critical roles such as file hosting, printing services, and network storage
    • Servers can be multipurpose or single-purpose, and dedicated or nondedicated
    • Dedicated servers specialize in specific applications or services, requiring fewer resources
    • Nondedicated servers are more flexible, expected to provide network services and local access
