Lua London Meetup 2013
Lua is a scripting language that can be embedded in large systems. The author initially found Lua irritating due to its verbose syntax and lack of operators like +=. However, Lua proved useful for applications like a web application firewall and camera scripting. Lua's performance, small size, extensibility and tables make it well-suited for these domains. Lua's metatables provide powerful abilities like sandboxing code, lazy loading, and object orientation. Overall Lua is a great embedded language once its initial syntax irritations are overcome.

Ppt for tranmission media
Transmission media are located below the physical layer and are used to transmit signals representing data. There are two main types of transmission media: guided media (wired), which provide a conduit for transmission, and unguided media (wireless), which transmit via electromagnetic waves without a physical pathway. Common guided media include twisted-pair cable, coaxial cable, and fiber-optic cable. Unguided media include radio waves, microwaves, and infrared. Each type of transmission media has different characteristics that determine its suitable uses.
Comm. and data communication
Communication involves a sender encoding a message and sending it through a medium to a receiver. It requires a sender, receiver, message, and medium. Common mediums include twisted pair cable, coaxial cable, fiber optics, radio waves, infrared, microwaves, and satellites. Twisted pair is commonly used for analog and digital transmission over short distances. Coaxial cable and fiber optics can transmit over longer distances due to better shielding and bandwidth. Wireless technologies like radio, infrared, and microwaves are used for line-of-sight transmission without cables. Satellites are used when direct transmission is not possible due to obstacles like the curvature of the Earth.
Data Communication And Networking
The document discusses different types of transmission media, including guided (wired) media like twisted pair cable, coaxial cable, and fiber optic cable, as well as unguided (wireless) media like Bluetooth, Wi-Fi, satellite microwave, and infrared. It provides details on each type of media such as its components, uses, advantages, limitations, and data transmission capabilities.
Transmission media and communication protocols
The document discusses various types of transmission media used in computer networks. It describes guided media such as twisted pair cable, coaxial cable, and optical fiber. Twisted pair cable comes in categories based on bandwidth and can be unshielded or shielded. Coaxial cable uses a central conductor surrounded by insulation and shielding. Optical fiber transmits signals in the form of light pulses through glass or plastic strands. Unguided media like radio waves, microwaves, and infrared waves transmit electromagnetic signals through the air without physical conductors. Each type of transmission media has characteristics like bandwidth, noise immunity, and cost that make some more suitable than others for different network applications.

There are two major classes of transmission media: guided and unguided. Guided media uses conductors like wires or fiber optic cables to transmit signals, while unguided media uses radio waves without a conductor. Common types of guided media include twisted-pair cable, coaxial cable, and fiber-optic cable. Each type has advantages and disadvantages related to bandwidth, distance limitations, noise interference, and cost.
