Chapter 1 1. What is free software? List three characteristics of free software. Free software is software that gives you the user the freedom to share study and modify it. We call this free software because the user is free. 1. Operational Characteristics‚ 2. Transition Characteristics‚ 3. Revision Characteristics. 4. What is the Free Software Foundation/GNU? What is Linux? Which parts of the Linux operating system did each provide? Who else has helped build and refine this operating system?

Activity 1: 1. Did any solutes move through the 20 MWCO membrane? Why or Why not? 2. Did Na+Cl- move through the 50 MWCO membrane? Activity 2: 1. Are the solutes moving with or against their concentration gradient in facilitated diffusion? 2. What happened to the rate of facilitated diffusion when the number of carrier proteins was increased? 3. In the simulation you added Na+Cl- to test its effect on glucose diffusion. Explain why there was no effect. Activity 3: 1. Which membrane resulted

Silaba Mpasu Physical Networking Unit 6 Exercise 1 Connector Installations Twisted-pair cable On a TWISTED PAIR CABLE I chose to install an RJ-45. This is the standard Ethernet connector for most systems used today. I would first measure out the length of cable that I would need. I would then use a wire cutter to cut the length that I need‚ leaving enough room for corrections and to open the wire. I would then use wire strippers to remove a small piece of the outer most jacket. I would then choose

centrality[1] Degree centrality shows how much a node connected with other nodes. For a node if more the number of direct connections with other nodes more the Degree centrality will be. Greater Degree centrality supports the chances of node to be active. To calculate Degree centrality let N is the set of all nodes in the network ‚ Degree centrality Cd of any node i then where (i‚ j) representing a link between node i and node j. n is the total number of nodes in the network. In figure 1 node C will
