• Network is free and has no boundaries, it helps us connect with each other, it helps us interact with one another regardless of the location.
• Servers are computers that provide information to end devices.
• E-mail servers run e-mail servers, web servers run web servers, files servers store corporate and user files.
• Clients are computers that retrieve information from the servers.
• Peer to peer network lets one computer run both server and client roles at the same time, it is designed for small networks.
• Advantages of peer to peer network include easy setup, less complexity, lower cost because network devices and dedicated servers may not be required while using this type of network.
• WAN interconnects many LANs over a wide geographical area.
• WANs use copper, fiber optic, and wireless transmission methods.
• LAN (Local Area Network) is a network infrastructure that only covers a small geographical area.
• Intranet is a private connection that is meant to be accessible only to an organization and its members and people who have authority within it.
• Whole Wide Network is a network type that connects hundreds of millions of computers worldwide that includes the internet itself.
• SOHO (Small office/Home office) is a network type that enables home or remote offices to connect to a corporate network.
• LAN interconnects devices in a limited area.
• WAN (Wide Area Network) is a network infrastructure that covers a wide geographical area.
• Internet is a connection of interconnected LANs and WANs.
• Extranet provides a secure access network for individuals who work for different organizations that need access to their data on their network.
• Medium to Large Network is a network type with many locations that has hundreds to thousands of interconnected computers.
• Network infrastructure varies greatly in terms of the area that is covered, the number of users that are connected, numbers and types of services that are available, and area of responsibility.
• DSL provides high bandwidth internet data that runs over a telephone line.
• Dedicated Leased Line is exclusive for corporate businesses and provides reserved circuits within the service provider’s network.
• Satellite provides internet connectivity using a satellite dish.
• Satellite can also be used for home office connections but is not available if the only internet connection is not available.
• Disadvantages of peer to peer network include no centralized administration, not secure, not scalable, and slower performance.
• Corporate business connections require high bandwidth, dedicated connections, and managed services.
• Business DSL is similar to a Normal DSL but is dedicated to a business approach.
• Global and PLDT provide internet connectivity using cellular phones with SIM cards.
• Ethernet WAN extends LAN access technology into the WAN connection.
• Converge Network is when data is carried to multiple devices over the same network infrastructure.
• Dial-up Telephone provides an inexpensive low-bandwidth connection using a modem.
• Cable provides high bandwidth internet data that is provided by a cable television service provider.
• Type of Connections include Cable, DSL, Satellite, Dial-up Telephone, and Cellular.
• Public Cloud is available to the general public through a pay-per-use model or for free.
• Network Security is the security of your network using a password or other terms of security.
• Hybrid Cloud is made up of two or more Cloud types, for example, part public and part private.
• Bring your own device allows users to use their own devices giving them more opportunities and greater flexibility.
• Cloud Computing allows users to store personal files or backup their data on servers over the internet.
• Online Collaboration allows users to collaborate and work with others over the network on joint projects using an online collaboration platform such as Zoom, Microsoft Teams, and Google Meet.
• There are four types of Cloud Computing: Public Cloud, Private Cloud, Hybrid Cloud, and Community Cloud.
• Converging Network is a network that prioritizes the bandwidth of live transmissions such as voice or live video, which means other devices connected to the network will receive less bandwidth due to it being slow.
• Video Communication allows users to communicate face to face using video platforms such as Messenger.
