DQ1 week 5 What is DNS? How do users benefit from it? Provide a brief description of the DNS process to resolve a URL to its IP address. Domain name systems (DNS) allows for an IP address to be assigned to a computer name or domain name. This system stores given names paired with IP addresses‚ which make identifying a computer on a network that much simpler. DNS follows an top-down heiratage‚ starting at the root on to top level‚ secondary level‚ subdomain level (optional)‚ and host level. Each

Pre – Lab Questions 1. A decomposition reaction may be defined as any reaction in which one reactant‚ a compound‚ breaks down to give two or more products. Write the balanced chemical equation for the decomposition of water to its elements. 2H2O(l) 2H2(g) + O2(g) 2. (a) Assign oxidation states to the hydrogen and oxygen atoms in each substance in the above chemical equation. The oxidation state of H2(g) and O2(g) is zero‚ because they are in their normal state. (b) Based

Full text search is a technique for searching a document or database stored in the computer. A full text search engine examines all the words‚ in every stored document‚ to find a match of the keyword searched by the user. Many web sites and application programs provide full-text search capabilities. There are quite a few choices when it comes to adding a full text search in a Ruby on Rails application. A choice can be made on the basis of the language the search engine is written in or the scalability

PreLab 1. Describe the different between a LAN switch/bridge and a router. LAN switch/bridge operate at the data link layer(layer2) and works based on the MAC address‚ while a router operates at the IP layer (layer3) and works based on IP addresses. 2. What is the difference between an Ethernet switch and an Ethernet hub? Which is more suitable for a network with a high traffic load‚ a switch or a hub? Explain. Ethernet switch is a store-and-forward device that operates at layer2

PRE-LAB QUESTIONS: 1) What cations are responsible for water hardness? Ca2+ and Mg2+ are responsible for water hardness 2) Calculate the mass of disodium Ethylenediaminetetraacetate required to prepare 250 mL of a 0.010 M solution. Mass = M x L x MM 0.010 M x 0.250 L x 372.24 g/mol = 0.93g of Na2H2Y 3) What is the molar concentration of the Na2H2Y solution? mol Ca = M x L 0.0107 M x 0.025 L = 2.65 x 10-4 mol if 1 mol of Ca = 1 mol Na2H2Y then: M of Na2H2Y = mol / L 2
