PASSAGE 1:

When a user enters a query into a search engine (typically by using keywords),  the engine examines its index and provides a listing of best-matching web pages according to  its  criteria,  usually  with  a  short  summary  containing  the  document  title  and sometimes parts of the text. The index is  built from the information stored and the method  by  which  the  information  is  indexed.  The  usefulness  of a  search  engine depends on the relevance of the results set it gives back. For instance, there may be millions of web pages that include a particular word or phrase, but some pages may be more  relevant,  popular,  or  authoritative  than  others.  Most  search  engines  employ methods to rank the results to list the "best" results first. How a search engine decides which pages are the best matches, and in what order the results should be presented, varies widely from one engine to another. Also, search engine ranking methods change over time as the way users interact with internet services changes and new techniques evolve.
Many search engines, such as Google and Bing provide customized results based on the user's activity history. This leads to an effect that is called a filter bubble.  The
term describes a phenomenon  in which websites use algorithms to selectively guess what information a user would like to see,  based on information about the user (such as location, past click behavior and search history).  As a result,  websites tend to show 
only  information  that agrees  with the  user's  past  viewpoint,  effectively isolating  the user in a bubble that tends to exclude contrary information.

To "recover"  data from  a bad  sector, one would  simply need  to issue  the Read Long command  instead  of the "normal"  Read  Sectors  command. That  is really  it!  It is so simple that any software developer  who is familiar with hard drives can do it. And sure enough,  more and  more data  recovery  tools  now come  with a Bad  Sector Recovery option.  In fact,  if  a tool  does not have a bad  sector recovery  feature,  it automatically falls into a second-grade  category.
Error checking  and correction  algorithms  were implemented  for a reason,  which is data  integrity.  When  a hard  drive  reads  a  sector  with  the  Read  Long  command,  it disables  these algorithms  and hence  there is no way to prove  that  you get valid data. Instead,  you get something,  which may or may not resemble your customer's data.
Tests in our lab  had shown that this approach allows you to get much more random bytes than  anything  else. Yes, there  are cases  where this approach  allows recovering original  data from  a sector.  But these  cases  are extremely  rare  in real  data recovery scenarios, and even then, only a part of the recovered  sector will contain valid data.
There  are tools  that claim better  bad  sector recovery.  But  they utilize  a statistical
approach,  an algorithm  where the tool reads the bad sector a number of times and then reconstructs  the  "original"   sector  by  locating  the  bits  that  occur  most  often  in  the

sector. While these tools claim this approach could improve the outcome, there is no evidence to back up the validity of such claims. Furthermore, re-reading the same spot many times while the hard drive is failing is a reliable way to cause permanent damage to the media or heads.

There are two important types of packet networks: connectionless packet networks and connection-oriented  packet  networks.  Connectionless  packet  networks  operate  in a way analogous to the post office. Connectionless  networks offer  best effort packet• delivery service.  Connectionless  packets are launched  into the network with a large and powerful header that contains all the information necessary to deliver the packet, whatever  its  destination.  As  a by-product  of  their  connectionless  nature,  it  is  not possible  to guarantee  performance  or reserve  network  resources  for  any particular communication, so connectionless networks do not support real-time services reliably. The switches in the network are stateless. When the network is subjected to overload, packets are buffered for later delivery.  If the buffer capacity is exceeded,  the packets are discarded. In connectionless networks there is  no guarantee that all packets  will traverse the same network path and be subject to the same delays. If a communication requires the transmission  of a series of packets,  it is up to the end stations  to ensure that the sequence is preserved.
Connection-oriented  packet networks have similarities  with both circuit networks
and packet  networks.  They  are like circuit networks  in that  a connection,  called  a virtual circuit, must be established before data can be transported.  Network nodes are 
prepared  to support  virtual circuits, and they devote resources  to them. The resources include  buffer  memory  and  link  bandwidth.  Assumptions  are  made  about the  traffic likely to be contributed  by a11 the sources, and the network  may overload  if a11 sources begin  sending  packets   at  their  peak  rate.  Occasional  pileups   of  traffic  are  to  be expected  and  are handled  by  maintaining  local  memory  to buffer  packets  until  it is possible  to transmit  them.  The  network  is  not  stateless.  When  all  the resources  are committed,  the  network   may  deny  requests   to  establish  new  virtual  circuits.  The headers    of   connection-type   packet    networks    can    be    shorter   than    those    of connectionless   networks  because  the  addressing  portion  of the  header  needs  only  to distinguish   each  virtual  circuit  from  each  other  established   on  common  links  and switch ports.

اسانسور ساختمانی 20 طبقه (از همکف الی طبقه 19) با ظرفیت حمل 1 نفر مفروض است. فرض کنید در هر طبقه 1 نفر زندگی میکند و در شبانه روز از اسانسور برای رفت و برگشت به دیگر طبقات استفاده میکند. الگوریتم حرکت اسانسور خالی برای توقف در طبقه درخواستی، در همان جهتی است که قبلا حرکت می کرده است( مثلا اگر هنگام حمل مسافر از طبقه 1 به سمت 4 حرکت کرده، پس از تخلیه مسافر، اسانسور به سمت طبقات 5 الی 19 حرکت میکند تا اگر کسی در این طبقات درخواست داشت، بایستد. سپس از طبقه 19 به سمت همکف حرکت میکند و اگر کسی در این طبقات درخواست داشت، می ایستد. اسانسور خالی مدام درحال حرکت و پیمایش طبقات است. در ابتدا خالی بوده و در طبقه همکف (صفر) قرار دارد) در صورتی که این مسئله، مشابه مسئله ناحیه بحرانی مدنظر باشد طوری که مسافران حکم فرایند (پردازه) و اسانسور حکم ناحیه بحرانی را داشته باشد. چند شرط از شروط ناحیه بحرانی (انحصار متقابل، پیشرفت، انتظار محدود ) نقض میشود؟
