Define LAN and WAN

. Local Area Network (LAN) A LAN is a network that is used for communicating among computer devices, usually within an office building or home. LAN’s enable the sharing of resources such as files or hardware devices that may be needed by multiple users • • Is limited in size, typically spanning a few hundred meters, and no more than a mile. Is fast, with speeds from 10 Mbps to 10 Gbps. Requires little wiring, typically a single cable connecting to each device. Has lower cost compared to MAN’s or WAN’s. LAN’s can be either wired or wireless. Twisted pair, coax or fiber optic cable can be used in wired LAN’s. Advantages of LAN : The data is transferred at an extremely faster rate in local Area Network. Local area network (LAN) provides higher security. Disadvantages of LAN : Initial cost of installing local area network is quite high. Unauthorized user can access critical data of an organization in case LAN ad...

Digital signal and wave form

. Digital Signal: A digital signal is a representation of information using discrete values, typically in binary code (0's and 1's). They have distinct levels or states, allowing for precise representation of data. Commonly used in digital communication, computers and electronic devices for transmitting and processing information. Digital signals are less susceptible to noise during transmission, making them reliable. Example: Binary-coded messages, digital audio data transmitted over the internet are all examples of digital signals. Digital Waveform: Digital waveform consist of voltage levels that are changing back and forth between the HIGH and LOW level as states. A waveform, on the other hand, is a graphical representation of a signal's amplitude as it varies with time. It shows how the amplitude of the signal changes over a specific period. Waveforms can be associated with both analog and digital signals. It used in signal processing, audio analysis and the study of e...
