Data Communication and Networking in English Session 2
Short Question
Q#17: What is Wide Area Network?
Ans:A wide area network (WAN) is a geographically distributed private telecommunications Network that interconnects multiple local area networks (LANs). A computer network in which the computers connected may be far apart, generally having a radius of more than 1 km.

Q#18: What is topology?
Ans:A Network Topology is the pattern in which nodes (i.e., computers, printers, routers or other devices) are connected to a local area Network (LAN) or other Network via links (e.g., twisted pair copper wire cable or optical fiber cable). There are four principal Topologies used in LANs: bus, ring, star and mesh.

Q#19: Describe Network Layer?
Ans:The main aim of this layer is to deliver packets from source to destination across multiple links (networks). If two computers (system) are connected on the same link then there is no need for a network layer. It routes the signal through different channels to the other end and acts as a network controller.

Q#20: Define Ring Topology?
Ans: Ring topology. Alternatively referred to as a ring network, ring topology is a computer network configuration where the devices are connected to each other in a circular shape. Each packet is sent around the ring until it reaches its final destination
Q#21: What are analog signals?
Ans: Analog Signals can have an infinite number of values in a range. An Analog Signal is any continuous signal, for which the time varying feature (variable) of the Signal is a representation of some other time varying quantity,
Ans:The Bandwidth of the composite signals is the difference between the highest and the lowest frequencies contained in that signals.
Bandwidth=fh-fl
Bandwidth=5000-1000
=4000Hz
=4000Hz
Q#24: What is the Ethernet?
Ans: Ethernet is the most widely installed local area network (LAN) technology. ... It touches both Layer 1 (the physical layer) and Layer 2 (the data link layer) on the OSI network protocol model. Ethernet defines two units of transmission, packet and frame.
Q#26: Describe time domain?
Ans: Time Domain refers to variation of amplitude of signal with time. Or how the signals change over time is called time domain

Q#27: What is sine wave?
Ans: The Sine Wave is the most fundamental from of a periodic analog signal. A sine wave can be represented by three parameters: The Peak Amplitude, Frequency, Phase.

Q#28: Define Port?
Ans:In the internet protocol suite, a Port is an endpoint of Communication in an operating system. While the term is also used for hardware devices, in software it is a logical construct that identifies a specific process or a type of network service.

Q#29: Define Serial Transmission?
Ans:In Serial Transmission one bit follows another, so we need only one communication channel rather than n transmit data between two communicating device. The advantage of serial over parallel transmission is that with only one communication channel. Serial transmission reduces the cost of transmission over parallel by roughly a factor of n.

Q#30: Define IEEE?
Ans: IEEE 802.2, 802.3, 802.5, 802.11. The Institute of Electrical and Electronics Engineers is a standards setting body. Each of their standards is numbered and a subset of the number is the actual standard. The 802 family of standards is ones developed for computer Networking

Q#31: Define Decibel?
Ans: The Decibel (abbreviated as dB, and also as DBAND DB) is a logarithmic expression of the ratio between two signal power, voltage, or current levels. ... A decibel is one-tenth of a Bel, a seldom-used unit named for Alexander Graham Bell, inventor of the telephone.
