But after establishing the internet, we can simply send a message in seconds anywhere on the planet.Along with this, data communication also provides us many benefits in day to day life, and some of the application includes interacting other people from web pages, nowadays there is no such task that can’t be accomplished through the website. As in earlier times, to send a simple message across the town, we had to use the post system and to wait for another week to get the reply. Explanation: Data communication and computer networks have made our lives simpler than the earlier time. These Java mcq sets will get youAcquainted with the nature of questions you may encounter during your Java interview or competitive exams forPopular programming language Java related career.Here you will find a list of common important questions on java programming in MCQ quiz style with answer for competitive exams and interviews.
![]() Advanced Java Mcq Questions With Answers Msbte Mac Address NetworkThe connector is a 48-bit mac address network interface card that helps to identify the devices and communicate with them. Ethernet cable comprises of a Cat – 5 twisted pair of coaxial cable with a connector called RJ – 45 (registered jack 45). Ethernet works on the specification 10 BASE – T, where T denotes the thick Ethernet cable, 10 represents the transmitting speed of 10 Mbps, and BASE depicts baseband. Fast Ethernet an extension of old Ethernet services with a data transfer speed of 100 Mbps and instead of coaxial cable, uses fiber optic technology for data transfer.Explanation: Ethernet is a widely deployed LAN technology. Ethernet is a widely deployed LAN technology.that uses Cat – 5 coaxial cable with an RJ – 45 connecters and consists of 10 Mbps speed for data transfer. But many services still use Ethernet cable.13) What is Ethernet in data communication? Ethernet works as a shared media device. Fast – Ethernet cable comprises of a Cat – 5 twisted pair of coaxial cable with a connector called as RJ – 45 registered jack 45. This Ethernet can work on ( UTP ) unshielded twisted pair, fiber optic wire, and wireless connection.Fast -Ethernet works on the specification 100 BASE – T, where T denotes the thick Ethernet cable, 100 represents the transmitting speed of 100 Mbps, and BASE depicts baseband. Carrier Sense Multi-Access / Collision Detection technology on detecting a collision rolls all its host back and wait for a random period and then again retransmit the data preventing all the collisions.14) What are Fast Ethernet and Giga Ethernet in data communication?I) Ethernet is a widely deployed LAN technology.that uses Cat – 5 coaxial cable with an RJ – 45 connecters and consist of 10 Mbps speed for data transfer.II) An extension of old Ethernet services with a data transfer speed of 100 Mbps and instead of coaxial cable, it uses fiber optic technology for data transfer.III) A modified version of Ethernet with a data transfer speed of 1000 MbpsIV) Shared media in Ethernet create one single Broadcast domain and one single Collision domainExplanation: FAST – ETHERNET:- Basically a modified extension of the older Ethernet cable. A shared media device has a high tendency to collide therefore, to reduce data collision risk, ethernet uses CSMA / CD technology.![]() ![]() Once the shared data reaches its destination, the terminator removes the line’s data for making space for more data. In general terms, a wire capable of transmitting Ethernet frames at a rate of a gigabit per second or 1 billion bit per second, making a revolution in the data transmitting industry.15) The network arrangement containing nodes, hubs/switches, and connecting lines circulating data from sender to receiver is called?Explanation: In this type of topology, all the devices are connected to a single cable, and the data is transferred from one end to another, and uses a line terminator. Carrier Sense Multi-Access / Collision Detection technology on detecting any collision, it rolls all its host back and waits for a random period, and then re-transmits the data preventing all the collisions.For fast emerging hardware and softwares, fast ethernet works on fiber optic medium and is defined as 100 BASE – FX, where FX denotes the Fast Ethernet over fiber optic cables, 100 represents the transmitting speed that is 100 Mbps, and BASE depicts baseband.GIGA – ETHERNET:- A more advanced and faster version of Ethernet cable with a specification of 1000 BASE – X, where X stands for – CX, -SX, -LX, or (non-standard) -ZX., 1000 represents the transmitting speed that is 1000 mbit/s, and BASE depicts baseband. The major drawback of using a star topology is that the central node is responsible for all the major work therefore, if at any point the central node fails, the whole system will collapse.Relatively faster and reliable than the bust topology as there is no single / common data transfer channel. All other devices are connected to this central node through cables forming a point – to – point connection between central nodes and all devices. Bus topology uses CSMA / CD technology.Attach image here – computer-network-mcq-q2122) Which statement/s is sutiable for Star topology ?I) Every device is connected to a single hub through a cable, the hub is the central control node, and all other nodes are connected to one central node.II) N is the desired number of cable to interconnect each channel.III) The amount of installation is high, and the complete processing depends upon the central node.IV) If somehow hub or the central nodes fails, the entire topology will collapse, making it more difficult to work.Explanation: Star topology consists of a main or a central node it can be a router hub or switch. The major drawback to this type of shared communication channel is that if the main shared communication line stops working in any circumstances, it will automatically cause the entire network’s failure. This type of network topology is least prone to failures because one device or host’s failure won’t crash the entire network. In that case, the data has to travel through all intermediate hosts sacrificing security and privacy, thus slowing the data communication rate.Attach image here – computer-network-mcq-q2324) Which statement/s is sutiable for Mesh topology ?I) Every device is connected to another device using a particular channel.II) N(n-1)/2 is the value to find the desired number of cable to interconnect each channel.III) Robust topology, fault can be detected very easily, provides utmost security and privacy.IV) High cable costing and installation is very difficult suitable for less number of devices, i.e., smaller network.Explanation: As the name suggests, Mesh topology consists of a multiple device communication networks, where each communicating device is connected to every other communicating device through point – to – point connection making it much more reliable, fast and secure. Suppose a device wants to send a message to a device that is not adjacent to it. If any node or connecting device fails, it will cost the entire system to fail in a ring-like structure.The data transfer speed is relatively slow compared to a star topology. Upgrading quicken for macThese are connected arbitrarily, according to the user. PARTIAL MESH – unlike full mesh, not all devices are connected to each other. And the number of wires connected can be calculated through n ( n -1 ) / 2.
