1) What is a LAN? LAN is short for Local Area Network. It refers to the connection between computers and other network devices that are located within a small physical location. 2) What is the difference between a normal LAN cable and cross cable? What could be the maximum length of the LAN cable? The way the paired wires are connected to the connector (RJ45) is different in cross cable and normal LAN cable. The theoritical length is 100 meters but after 80 meters you may see drop in speed due to loss of signal. 3) What id DHCP? Why it is used? What are scopes and super scopes? DHCP: Dynamic host configuration protocol. Its used to allocate IP addresses to large number of PCs in a network environment. This makes the IP management very easy. Scope: Scope contains IP address like subnet mask, gateway IP, DNS server IP and exclusion range which a client can use to communicate with the other PCs in the network. Superscope: When we combine two or more scopes together its called super scope....

1. Expand ECE ? Electronics & Communication Engineering. 2. What is Electronic? The study and use of electrical devices that operate by controlling the flow of electrons or other electrically charged particles. 3. What is communication? Communication means transferring a signal from the transmitter which passes through a medium then the output is obtained at the receiver. (or)communication says as transferring of message from one place to another place called communication. 4. Different types of communications? Explain. Analog and digital communication. As a technology, analog is the process of taking an audio or video signal (the human voice) and translating it into electronic pulses. Digital on the other hand is breaking the signal into a binary format where the audio or video data is represented by a series of “1”s and “0”s. Digital signals are immune to noise, quality of transmission and reception is good, components used in digital communication can be produced with high preci...

1. Which cut is used for solid blasting in Indian coal Mines Wedge cut 2. Permitted explosives are safe to use because Special chemical are used to extinguish the spark produced during blasting. 3. Burden is the distance between Distance between first row of blast holes and bench 4. Which of the following explosive have maximum strength RDX 5. To measure the performance of blasting which factor is calculated Powder factor 6. What is the formula for blast ability? B = c / t Where B = Blast ability c = compressive strength t = tensile strength of a rock 7. As per provision of regulation 170 (1a)(of CMR 1957 danger zone is an area falling a radius of ——– 300m 8. While blasting in hot strata the temperature of hole should not exceed 80 c 9. Fly rocks during opencast blasting is controlled by muffled blasting 10. While dealing with Misfire shot the relieving hole is drilled at a distance not less than 10 m 11. As per CMR the recapping of rope is done once at least in every 6 months 12. what...

1.What are the characteristics that keep solid and fluid different? When the force is applied tangentially on solid then it experiences a finite deformation and shear stress that is proportional to the deformation. Whereas, when the same shear stress is applied on the surface of fluid then it experiences continuous increasing deformation where, the shear stress is proportional to the rate of change of deformation. The fluid dynamic is dividend in three different areas. They are as follows: Hydrodynamics (flow of liquids), Gas dynamics (flow of gases) and Aerodynamics (flow of air). Whereas, the state of, solid doesn’t represent any of the stages. 2.What are the objectives of Aerodynamics? Aerodynamics deals with the theory of flow of air and it has many practical applications in engineering. There are some objectives that are being used in aerodynamics and these are as follows: It is used to predict the forces, moments and heat transfer from the bodies that is moving through the liquid...

1.What is therapeutic cloning? In the process of cloning DNA or a part of DNA is duplicated. This process is also called somatic cell nuclear transfer. In this process embryo is utilized for cloning. Embryo comprises of stem cells which is later employed in regeneration applications. The embryonic stem cells are renewable and are pluripotent. 2.Explain the mechanism of ELISA. What are its uses? ELISA stands for enzyme linked immunosorbent assay. It is a wet lab type analytical biochemistry assay. It can detect presence of a substance in a liquid or wet sample by using one subtype of heterogeneous, solid-phase enzyme immunoassay. ELISA can be used as ligand binding assays. It is also used as a diagnostic tool in medicine and plant pathology. Quality check operations can also be performed in various industries with the help of ELISA. 3.Explain microarrays. How are they related to DNA? Microarrays are matrix in the form of arrays where DNA oligonucleotides of DNA sequences are spotted. Th...
