Understanding Computer Organization and Network Communication

💻 Computer parts are divided into hardware and software.

🔌 Hardware refers to the physical components of a computer.

💡 Software consists of programs that run on the computer.

📦 There are different subcategories of computer parts, including network devices, storage devices, input devices, and output devices.

💻 Output devices transform digital information stored inside the computer into physical information that humans can understand and interact with.

🔊 Output devices for audio, such as speakers and sound cards, allow the computer to give audio signals and play music.

🖥️ Monitors, video cards, and projectors are examples of output devices that display visual information by turning digital numbers into visual pixels.

🖨️ Devices like printers, including laser, inkjet, and 3D printers, turn digital information into physical objects.

⌨️ Input devices allow users to interact with the computer and convert physical data into digital data.

📷 Various input devices, such as touchpads, keyboards, and microphones, capture and store information from the outside world.

💡 Computers have input devices that gather information, output devices that display information, and storage devices that remember and store information.

🔒 Storage devices in computers can be categorized into primary storage and secondary storage. Primary storage, known as RAM, is used for quick calculations but is cleared when the power is turned off. Secondary storage provides extra memory.

⚡ RAM is very quick to access but requires power and constantly changes.

🖥️ Primary storage in computers is used for normal activities and calculations when the computer is on and operating.

🔒 Secondary storage is where data can be stored permanently, examples include CDs, USB drives, hard drives, floppy discs, and cloud storage.

🌐 Network devices facilitate communication between computers, with routers being the central machines that receive and analyze data from computers.

🌐 A computer organization is like a traffic controller that routes data from one computer to another.

🏢 Local Area Networks (LANs) connect computers in the same building using one router, while Wide Area Networks (WANs) connect computers far apart using multiple routers and special cables.

🌍 The Internet is an example of a WAN, connecting computers worldwide by linking together smaller networks with routers.

📡 Routers are important network devices that receive and analyze data sent from other networks.

🔌 Ethernet ports allow for a physical connection between a computer and a router using an ethernet cable.

📶 Wireless internet cards, or Wi-Fi cards, enable connection to a router through the use of radio waves.
