3. System Calls A system call is simply a kernel function that a wier application can we to aocess or utilize system rewources. Functions forki), and exec() are well-known ccamples of syatem calls in UNIX and xv6. We will use a simple ceample to walk: you through the steps of adding a new system call to xv6. We name the syset call epdi), which priats out the current running and slecping processet. An application signals the kemel it needs a service by issiing a software internapt, a signal generated to bocify the peoceser that it neds so slop its current takk, and repponse to the signal request. Before switching to handling the new taxk, the proceswor has to save the current state, se that it can resime the execution in this context after the requeat has becn hathllod. The followisg is a code that calls a sysern call in xv6 (found in wibcode 5 ): (iqtobl atare otarti pinh sarge Fwhi binle wo where caller po wosid be Basically, it pushes the aggument of the call to the stack, and puts the systen call number, which is $5YS ewe in the example, into Fiear. All the sysucm call mambers ate sperified and saved in a table and the syacem calls of xv6 can be found ta the flle macall. Next, the code ied ST STSCAL. genctates a software interrupe, indecing the intemupt descriptor table so doeaid the appeopriane incerupt handler. The functive trap() (in map. c) is the specific code than finds the appeopriale imemupt handler. It checks whether the trap number in the penerated tranframe (a senachure representing the processer's stans at the time the erap happened) is cyual to T SYSCAL. If in is, in calls syscallo, the sodtware interrupe handler thar's available in nscalle. The finction syscallo is the final function that checks out Fiear to obeain the system cal's number, which is ward to index the able with the system call poimers and to etecute the code comespoding to that sysuce call: The following are the procedures of adding our evemplary system call cpso to xv6. a.

3. Producer surplus for a group of sellers The following graph plots a supply curve (orange line) for several sellers in the market for polaroid cameras in College Station, a university town in Texas. Each seller has a single polaroid camera for sale. The market price of polaroid cameras is given by the horizontal black line at $70. Each rectangle on the graph corresponds to a particular seller in this market: blue (circle symbols) for Hubert, green (triangle symbols) for Kate, purple (diamond symbols) for Manuel, tan (dash symbols) for Poornima, and orange (square symbols) for Shen. (Note: The name labels are to the right of the corresponding segment on the supply curve.) Use the rectangles to shade the areas representing producer surplus for each person who is willing to sell a polaroid camera at a market price of $70. (Note: If a person will not sell a polaroid camera at the market price, indicate this by leaving their rectangle in its original position on the palette.) Based on the information on the preceding graph, you can tell that will sell polaroid cameras at the given market price, and total producer surplus in this market will be Suppose the market price of a polaroid camera increases to $110. On the following graph, use the rectangles once again to shade the areas representing producer surplus for each person who is willing to sell a polaroid camera at the new market price: blue (circle symbols) for Hubert, green (triangle symbols) for Kate, purple (diamond symbols) for Manuel, tan (dash symbols) for Poornima, and orange (square symbols) for Shen. (Note: If a person will not sell a polaroid camera at the new market price, indicate this by leaving their rectangle in its original position on the palette.) Based on the information in the second graph, when the market price of a polaroid camera increases to $110, the number of sellers willing to sell a polaroid camera to , and total producer surplus to.

List the steps in generating an action potential (depolarization) and the reestablishment of the resting potential of a neuron. Include the way the ion channels open and close and what ions go in and out of each (see table 6.2). 5. Name and explain (not simply state) the principal actions of three neurotransmitters of your choice from 6. Distinguish between the four tissue layers of the Gl tract wall by stating the primary tissue type present the neuron. and describing by stating the number of layers and functions for each. You may be asked to label a figure Table 11.1. like one in the textbook. 11.1 The Nervous System Has Two Principal Parts The nervous system includes the central nervous system (CNS) D and the peripheral nervous system (PNS) D. The CNS consists of the brain and the spinal cord. It receives, processes, stores, and transfers information. The PNS includes the components of the nervous system that lie outside the CNS. The PNS has two functional Figure 11.1 Components of the nervous system. The CNS receives input from the sensory component of the PNS, integrates and organizes the information, and then sends output to the periphery via the motor components of the PNS. subdivisions: the sensory division of the PNS carries information to the brain and spinal cord, and the motor division of the PNS carinformation from the CNS to other partt pody (Figure 11.1 )..

3. Indifference curves and preferences Eric enjoys both pretzels and cookies. Assume that the "more is better" principle holds for Eric, meaning that he would always prefer to consume more of either good, holding the level of consumption of the other good constant. The two figures below present information regarding Eric's preferences. The points on Figure 1 represent combinations of cookies and pretzels that Eric might choose to consume. Figure 2 plots the same points as Figure 1 , but it also shows some of Eric's indifference curves: I1, I2, and I3. Thus, Figure 2 gives more insight into Eric's preferences than Figure 1. Complete the following table by indicating which bundles Eric strictly prefers to A given only the information in each figure. Indicate whether each of the following statements is true or false given the graphs..

3. In GSM, (a) We assume that each subscriber has been assigned an IMSI (i. e. International Mobile Subscriber Identity), and this information is public nown. If we want to provide a service to hide this information even during the initial connection (i.e. including the registration), suggest one solution to isfy this requirement. You need to point out how and why this solution can protect IMSI. (no more than 30 words) (b) Multiple SRESs and RANDs are stored at VLR for authentication purposes, where SRES=A3( Ki, RAND) and Ki is a pre-shared secret key between the mobile subscriber and HLR. SRES needs to be protected and used as evidence to collect a service fee. Since SRES is known by both mobile subscribers and VLR, repudiation cannot be resolved. If we want to establish a partially non-repudiation service between the mobile subscriber and VLR. suggest one solution to meet this requirement. (no more than 30 words) 4. In most wireless communications, there are 3 entities involved in connecting a call: Mobile Subscriber (MS), VLR, and HLR. (a) Suggest a method that MS can protect its identity when MS roams into a new VLR region. (i.e. MS does not need to expose its real identity to the attacker when makes the first connection through VLR) (b) If only VLR and HLR have digital certificates, can a secure channel be established between the MS and VLR? ( If your answer is YES, you need to explain how.) 5. In SSL and TLS, why is there a separate Change Cipher Spec Protocol rather than including a change_cipher_spec message in the Handshake Protocol? 6.
