Network

• A network is a collection of devices that are connected to one another.
• Networks can be wired or wireless, local or wide area networks (LAN/WAN).
• The main components of a computer system include the CPU, memory, storage, input/output devices, and software.
• Computer systems have different types of processors such as Intel Core i3, i5, i7, AMD Ryzen 3, 5, 7, etc., with varying speeds and capabilities.
• Local Area Network (LAN) - A LAN connects multiple devices within a small geographic location such as an office building.
• Computer systems have different types of processors such as microprocessors, microcontrollers, digital signal processors, graphics processing units, and central processing units.
• Computer networking allows computers to communicate with each other over long distances.
• Memory stores data temporarily while it's being processed by the processor.
• Wide Area Network (WAN) - A WAN covers a larger geographical area than a LAN and may span across countries.
• Metropolitan Area Network (MAN) - A MAN provides high-speed data transfer over a large city or metropolitan area.
• A network is a group of interconnected devices that can share resources and communicate with one another.
• Input devices allow users to interact with their computer by providing data or instructions.
• Network topology refers to how nodes or devices are arranged on a network.
• A network is a group of interconnected computing devices that can share resources and communicate with one another.
• Local Area Network (LAN) - A LAN is used within an office building or campus environment.
• The Internet is a global network connecting millions of smaller networks around the world.
• Personal Area Network (PAN) - A PAN connects personal devices like smartphones, tablets, laptops, and wearables together.
• Home Area Network (HAN) - An HAN connects home appliances and entertainment equipment together.
• Bus Topology - All devices connect directly to a single cable called a bus.
• Wide Area Network (WAN) - A WAN spans large geographic areas such as countries or continents.
• The three main types of network topologies are bus, star, and ring.
• Star Topology: Each device has its own connection to a central hub or switch, allowing for more flexibility but requiring additional cabling.
• Metropolitan Area Network (MAN) - A MAN covers a large geographic area such as a city or town.
• Bus Topology: All devices connect directly to a single cable called a backbone, which acts as a shared communication pathway.
• Wide area networks (WAN): Cover a wider geographic area such as cities, states, or even entire countries.
• Local area networks (LAN): Connect computers within an office, school, or home.
• The main types of networks include local area networks (LAN), wide area networks (WAN), and metropolitan area networks (MAN).
• Metropolitan Area Network (MAN) - A MAN covers a large city area and provides high-speed internet access to businesses and organizations.
• Wide Area Network (WAN) - A WAN spans over long distances and includes multiple countries.
• Computer networking involves using hardware components to create a communication system between computers.
• Star Topology - All devices are connected directly to a central hub/switch.
• Personal Area Network (PAN) - A PAN allows devices like smartphones, tablets, and laptops to be connected together wirelessly.
• Mesh Topology - Every device has its own connection to every other device on the network.
• Star Topology - Each device has its own connection to a central hub.
• Mesh Topology - Every device on the network is connected to every other device.
• A bus topology has all devices connected to one long cable with no central hub.
• Ring Topology - Devices are connected by two cables forming a ring.
• In a star topology, there is a central device that acts as a hub or switch, which all other devices connect to via separate cables.
• Ring Topology: Devices are connected in a circular pattern with data traveling around the ring from one device to another until it reaches its destination.
• A local area network (LAN) can be set up using either wired or wireless connections.
