Past Announcements for Spring 2026

• (4/28) SA11 extended It is now available until 5/1@17:00
• (4/28) Typo SA11 One of the multiple choice answers reads "busy-wating" instead of the correct "busy-waiting".
• (4/21) Reminders: SA9, SA10, SA11 Expiration date/time for their availability is tomorrow Wed (4/29) at 17:00.
• (4/21) Reminders: SA8 and HW3 Expiration date/time for their availability is tomorrow Wed (4/22) at 17:00.
• (4/16) Subject 9 PDF : minor typo Slide 27, line 8, shows a 1/2000ms. This should have been 1/400ms. The 0.002ms is consistent with that though the correct, not approximate answer would have been 0.0025ms.
• (4/08) Clarification/Correction Subject 8: PDF 51 The slide says "1 TLB per CPU"; the meaning of a CPU is the generic/traditional one of a unicore CPU, the CPU introduced in Subject 1. For multi-core CPU there might be one TLB per core or more. The number of entries for a TLB varies from 8 to 512 or so. However the number is fixed (constant) per system rather than number of process dependent.
• (4/07) Reminders: SA7, SA8, HW3 All are active and available in canvas. Be reminded: start at least one of them if you expect to be able to see the questions later. SA7 will be available until next Wed (4/15), SA8 will be available until the Wed after (4/22), and so is HW3 (4/22) with all available until times running to 17:00 on the Wed indicated.
• (4/01) Exam 2 grading and midterm class performance On Thu 4/2 around 11:59am I will post in canvas Announcements the following: (a) Exam 2 statistics, (b) a midterm class performance based on Ex1, Ex2, HW1, HW2 grades providing a rough letter guidance (A, B+/B, C+/C, D/F), and later on Thu (c) a solution key of Exam 2 both in canvas Announcements and section C of the course web-page.
• (3/26) Solution key for HW2 Available in Canvas Announcements and Section C of the CWP.
• (3/24) Exam 2 and returning it The expectation is that the 3/31 exam (Exam 2) will be graded and returned the following class 4/2. I will ask you, just as in the first exam, to get seated according to the seating arrangements of the exam, so that i can return your paper exam as smoothly as it was the case for Exam 1. For addtionl Exam 2 info see also the item below.
• (3/24)(3/23)(3/20) Exam 2 The exam is scheduled per the Calendar of Document 1 (Syllabus). As indicated there its date is Tue 31 March. Coverage of the exam includes Subjects 3, 4, 5, and 6 and thus Chapters 3, 4, 9, and 10 of the designated textbook. Practice for this material includes SA 3, 4, 5, and 6, and HW 2 in addition to the examples covered in the classroom. Weather-permitting the exam will be graded and returned on Thu 2 April. By that time or afterwards on Thu a midterm class performance (rough letter grade guidance) will be made available in Canvas announcements based on the grades of Exam 1, Exam 2, HW 1 and HW 2. If you have not picked up your Exam 1 yet, do pick it up before April 1, during regular office hours.
• (3/23) Reminders re SA4, SA5, and SA6 plus HW2 All four are available until 17:00 tomorrow Wed 3/25. A reminder re the SAs. If you submit one for a fifth time, you would be able to see the correct answers in addition to the questions IMMEDIATELY! Or you can wait until after AVAILABLE UNTIL when they become available to ALL. Of course to see answers or questions you need to have submitted at LEAST ONCE. If you ignore an SA or a HW, you won't be able to review the questions let alone the answers. For HW2 the same apply; moreover for a HW a solution key becomes available in Canvas Announcements sometime after the AVAILABLE UNTIL date/time. Finally, as a reminder: take screenshots a.k.a. generate a digital copy of an SA or a HW.
• (3/23) Confusing meaning Subject 6 Page 17 (PDF) line 8 has a "2 p". Though not technically wrong, it makes more sense to either read it as "1 p ", or read this and the previous line as "1. 1" and "2. p" respectively.
• (3/12) Spring break and work ahead Next week 3/17 and 3/19 for us is Spring break. Note however after the break there are SA4, SA5, and SA6 due, in addition to HW2 on 3/25 before 17:00. Effective after the break, attendance will be monitored. Prior to the break attendance was monitored on two instances: the day of Exam 1, and the Thu before, the practice session. Attendance will affect the number of bonus points credited, with a reduction of 50% every missed class beyond ONE excused absence by a Dean of Students email, and ONE no-excuse needed (e.g. missing the practice session).
• (3/11) Subject 5 typo Slide pdf page 34 of Subject 5. "Be careful ... these number." The word number must be in plural i.e. it should read "numbers."
• (03/05) Programming Challenge To the few of you who submitted it: you will be receiving feedback by next Tue (3/10).
• (3/4) (02/24) Subject 3 typo Slide pdf page 74 of Subject 3. In FILE TABLE on the right the count indicates a 2 instead of a 3 for three processes with pid 2,4,5. In other words the FILE TABLE should look like the one on the previous page 73.
• (03/02) Exam1 grading Exam 1 grading is to be completed today. The Exam will be returned on Tue. Please get seated on Tue 3/3 using the arrangements used on exam day to expedite the return of the graded Exam 1 paper. On Tue 3/3 at noon time Canvas Announcements will have Exam 1 statistics. The solution key will become available there around 18:00. Though every effort was made and I double checked the sum (grade) indicated on the cover page do double check the sum on receipt of your exma paper, just in case. You may resolve issues during the two week period starting tomorrow 3/3. And as a reminder, Exam 2 is on in 4 weeks from tomorrow!
• (02/25) Exam1 As of now, Exam 1 will finally take place on Thu 2/25.
• (02/24) Subject 3 Typo Slide pdf page 74 of Subject 3. In FILE TABLE on the right the count indicates a 2 instead of a 3 for three processes with pid 2,4,5. In other words the FILE TABLE should look like the one on the previous page 73.
• (02/12) Exam1 Reading list: Subject 0, 1 and 2 including Chapters 1 and 2 of the designated textbook. Practice list: SA 0,1, and 2, HW 1 and what we did in class offers minimal practice. Practice makes perfect.
• (15:35)(14:47 Update)(02/23) Inclement weather situation and Tue 2/24 The exam, Exam 1, scheduled for Tue 2/24 has moved to Thu 2/26. On Tue 2/24 there will be an online class through Zoom. I will post meeting info in Canvas shortly before 16:00 today. The topic that will be covered on Tue 2/24 will be Subject 3 (partial coverage). It is important to attend the Tue Zoom section, because it is essential part of the next exam, Exam 2. Moreover office hours Tue 2/24, 10:00-11:00am have been cancelled. I will extend Thu 2/26 hours 10:00-Noon. A message has been sent through canvas announcing the modifications outlined above on what is going to happen with respect to the class of 2/24. There are also two announcements in Canvas/Announcements. The Zoom area in Canvas has the meeting link for tomorrow's Zoom meeting. The meeting is password protected (available in the Canvas announcement zoom item)! As of now (09:47@2/23) NJIT has cancelled all Mon 2/23 classes. The fate of Tue 2/24 classes is currently unknown. IF and I reiterate IF, Tue 2/24 classes move ONLINE or get cancelled, the paper exam of 2/24 will move to Thu 2/26 as a paper exam. But as of now (09:47@2/23) the Tue 2/24 paper exam is to be held as scheduled.
• (02/21) Canvas Grades and HW1 HW1 has been graded and will be released at 5pm today. Note that at release time you can only see your answers of the last attempt in addition to questions and correct answers (as also shown in a separate solution key). However, there has been reported by some of you the following abnormal behavior of Canvas: in Grades the last attempt's score is reported INSTEAD of the HIGHEST score. I have already sent out a message through canvas to alert you about this. It has nothing to do with my setup (see attachment of that message) as far as i can see but it is something that canvas is not handling well. Never happened before. However, we maintain grades in a separate file, and the correct grade would be recorded (the highest). Now this confirms what i have been telling you since the beginning of the semester re canvas synchronization issues. I have reported this problem to IST @ NJIT. I do not expect any response before Monday. But it would be nice if Canvas/Grades reports consistently with the setup of a Quiz.
• (02/20) Connectivity, Secure Shell (Mobaxterm), Linux review On Thu 2/19 we had a review demonstration of how to use one Windows-based secure shell clinet (MobaXterm) and a demonstration around Linux. If you need more on these go to (a) Section B of the course web-page, section B3 and items B.3.1, B.3.2 and B.3.5 that are linux related, and B.3.4 that is VPN Connecivity and Secure Shell connectivity related, (b) Canvas Modules , Module 0, where you may find four relevant links: (b1) How to extract files from a tar archive, (b2) CS332 Moba Xterm, (b3) CS332 Linux, and (b4) CS332 Vpn Client.
• (02/19) SA0, SA1 have been released SA 0 have been released for a while. SA 1 was released yesterday. Always start a quiz (SA or HW). Whether you submit it explicitly or canvas submits it for you (as long as credentials do not expire in between), the following step is trivially possible: we release quizzes for a two week period afterwards, with afterwards meaning either Available Until date has passed or a homework has been graded. Then you can have the questions of the quiz (SA or HW) available to you, your answers of the last submission, and the correct answers. If your last submission is empty of your answers our multi-suggestion since the start of the semester applies: TAKE SCREENSHOTS BEFORE YOU SUBMIT or after a quiz gets released to you for YOUR RECORDS. If you do not start/submit a quiz after release nothing will be visible to you. Furthermore, note that for a self-assessment on the fifth submission you may see the correct answers as well.
• (02/19) Reminder: NJIT LEVEL ALERT (Friday evening - Sat morning) As you might have already read an NJIT email, NJIT platforms would be unavailable Fri to Sat (2/20 to 2/21) because of a security update. Platforms affected are Canvas, Webmail, etc. More info on the NJIT relevant email.
• (02/19) HW1 and solution key HW1's solution key has been made available in Canvas Announcements since yesterday Wed and also on the course web-page section C. The HW will be released in canvas around 5pm on Saturday.
• (02/12) Exam1 Reading list: Subject 0, 1 and 2 including Chapters 1 and 2 of the designated textbook. Practice list: SA 0,1, and 2, HW 1 and what we did in class offers minimal practice. Practice makes perfect.
• (02/10) Seating Arrangements (Exam 1 and Exam 2) They have been posted in Canvas/Announcements. The list includes a triplet of (Exam#, FirstName+Initial, Last-3-digit-NJITID). Use Exam# to retrieve your exam room location. There will be a practice seating on the Thur before Exam 1. (Exam 1 is on Tue 2/24 therefore the practice seating will take place on Thu 2/19).
• (02/17) Practice Session for Exam 1 on 2/19 On Thu 2/19 you will be seated in the classroom based on your exam number. Prior to attending class go to Canvas Announcements and read the announcement's attached document re the seating arrangements for Exam 1 and Exam 2. Identify your exam number (a three digit number on the left of what NJIT thinks is your First/Middle name). Note that to the right of your First/Middle name you may also find the LAST 3 digits of your NJIT ID. Compare them to your NJIT ID; on the exam paper you need to write down the LAST 4 digits of your NJIT ID, WHICH IS NOT your LIBRARY ID. Make also sure that on the Exam date, you bring to the classroom a valid ID: the NJIT ID is more than enough.
• (02/06) Typo Subject 2 page 72 Second line says "Context switch time is 200ms". It should read "I/O time is 200ms". This brings it in line with page 61. Then the implication is that "context switch time is 400ms".
• (02/06) Typo Subject 2 page 61 First line (under the header) "slided use" should better read "sliced use". This slide can be used as a guide for Q11 of HW1.
• (02/05) Comment on SA0 If you did not study Subject 0 (the notes in pdf) pay more attention and study page 9 of it. Around 45% of you did not read it. You are going to regret it later if you think b stands for bit. And around 50% of you did not study carefully slide 33 and its first two lines under the header... There are other hit and misses. SA0 might have been forgiving in assessing your performance but the remaining SAs, Hws and Exams will not: they will be rigid!
• (02/05) Reminder: SA1, HW1 They are still active in Canvas.
• (02/02) Reminder: SA0 SelfAssessment 0 (aka SA0 or SA00) will cease to be available at 17:00 on Wed 2/4.
• (01/27) Office hours today Tue 10-11am cancelled See Canvas/ Announcements for details. Thu 1/29 office hours would be extended by 1 hour: new Thu 1/29 hours will be 10:00am-12:00 noon.
• (01/26) Zoom meeting tomorrow Tue : See Canvas Announcements NJIT announced around 6:00pm today that on Tuesday 1/27/2026 all classes will meet in Zoom. Our class will thus be in Zoom. If you go to canvas and click on the Zoom area (between Modules and Grades) you will see a link named SP26-CS332 etc. Do not click it NOW but just prior to the class! Read the corresponding Canvas Announcement item before you go Zoom! You need to use your njit.edu email and thus login with your myUCID credentials in zoom. And you need to provide a PASSCODE. This passcode is prominently displayed in the Canvas Announcement of the Zoom meeting and it is a six digit number (denary, radix-10:-). Note that by default you will be muted on entering zoom.
• (01/26) HW1 and SA1 arriving On Tue HW1 will become available in Canvas and also SA1. Due (Available until) date info for HW1 in the Syllabus (Document 1, Calendar, page 3), in Canvas/Quizzes and also Canvas/Assignments. Due (Available until) date info for SA1 in Canvas/Quizzes and also Canvas/Assignments. There is an area in canvas known as "Syllabus". It has nothing to do with Document1; it contains however Available until information for all assignments of the semester (SA or HW). Finally note that Verification of Presence (a.k.a. Academic Engagement) is due in canvas: however this is between YOU and the REGISTRAR/Provost, and does not require instructor interference.
• (01/21) TA (a.k.a. grader, assistant) Her information has become available in Canvas/Announcements as a separate message. Moreover, part of it (not the zoom link number) is available in this CWP (Course Information section, before Section A).
• (01/20) First day of classes is today Tuesday A self-assessment (SA0) is available in canvas. It can be reached through Canvas Assignments, or Canvas Quizzes, or Canvas Modules and the name of the module is Subject 0. It is set-up as a canvas quiz, five attempts, max score is used after it is rounded up (a 2.1 becomes a 3, but a 2 remains a 2). It is of limited availability. Take screenshots and make a digital copy for your records for future use. It becomes available for a limited period, then it ceases to be available, it is graded by canvas and supervised by a grader (info TBA), then it is released for two weeks (you can see questions, your answers and correct answers) and then it disappears. The latter is possible if the LAST submission is your good submission; if the last submission is empty because of canvas limitations you will only see the questions, and maybe the correct answers. Therefore take a screenshot (a.k.a. digital copy) BEFORE submission, and another one AFTER the release AFTER grading.
