Define terminologies for transmission impairments

 .

Here are some commonly used terminologies in the context of transmission impairments:

  1. Attenuation: Attenuation is the reduction in signal strength as it travels over a distance. It is caused by various factors, such as resistance, inductance and capacitance, in the transmission medium.
  2. Distortion: Distortion occurs when the signal is altered or distorted during transmission, resulting in errors or corruption of the original signal. Distortion can be caused by various factors, such as noise, interference and nonlinearities in the transmission medium. 
  3. Noise: Noise is an unwanted signal that interferes with the original signal during transmission. It can be caused by various sources such as electromagnetic interference (EMI), crosstalk and thermal noise.
  4. Interference: Interference is a form of noise that is caused by external sources, such as other electronic devices or radio waves. It can cause distortions in the original signal and affect the quality of the transmission.
  5. Delay: Delay is the amount of time it takes for a signal to travel from the transmitter to the receiver. It can be caused by various factors, such as the distance between the transmitter and receiver, the speed of the transmission medium, and the processing time of the equipment.
  6. Jitter: Jitter is the variation in the timing of a signal as it is transmitted over a distance. It can be caused by various factors, such as interference, noise and variations in the processing time of the equipment.
  7. These are some of the commonly used terminologies in the context of transmission impairments. Understanding these concepts is important for designing and maintaining reliable communication systems.

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...

Introduction of Computer

.  A computer is an electronic device. It take input and store the data in memory and performing the function to produce accurate result in output device. It is used to type document, send email, play game, browse the web and entertainment.   Characteristics of computer  1 . High speed  Computer is very fast device. It is capable of performing calculation of very large amount of data. The computer has unit of speed in microsecond, nanosecond and even in picosecond. The computer is capable of performing millions of tasks per second. 2. Accuracy  The computer produces highly accurate and reliable result.  It does not make any kind of mistake in calculating. The calculation are 100% error free. The computers perform accurate 'n' number of times. 3. Storage capability A computer has much more storage capability. It can store large amount of data. It can store any type of data such as image, video, text document, audio and many more. 4. Diligence Diligence ...
