W: Hey Miguel, how’ve you been lately?
M: Stressed. I have to do this big project for my government class, and I need to use a computer to do it. [1]I don’t know much about the computer facilities here on campus. Do you know anything about how the computer labs work here?
W: Actually, I worked as a part-time student employee in one of the open labs for two semesters. What do you want to know?
M: Wow, great! Well, first of all, where are they? I know there are quite a few labs spread throughout the school, but I am not sure where they are.
W: Well the open labs are in Murphy Hall and in the basement of the library. There is also another lab just for liberal arts majors in the arts building.
M: Oh, OK. They’re all there together. Are they open 24 hours?
W: Unfortunately no. [2]They’re open from 8 am. to 9 p.m. Monday through Thursday. 9 to 5:30 on Friday. During the fall and spring semesters they’re open Saturday and Sunday until 5.
M: Uh huh, and do they offer any kind of training on the computers?
W: Yes, they do actually. They hold computer training workshops twice a month. You can sign up for one in the library. [3]There are also instructional tutoring sessions for students who need help with their course work in the individual labs, and of course, individual assistance is available, too.
M: Can I just walk in and start using a computer, or do I need a password or something?
W: You do need a student account and password to show that you actually attend the university. Once you show them your student ID card, they will set up an account for you and give you a password. Actually, I have a pamphlet in my bag if you want to take a look.
M: Yeah, sounds good. Hey, this says I can only use the computer for one hour. Then I have to check out of the lab. Why is there a one-hour limit?
W: [4] Well there are only 30 computers, so that way all students can get an opportunity to use them. Last year, some of the waiting lines were getting very long, and people complained about waiting for long periods of time. Some people couldn’t complete their assignments on time.
M: Ah. It says here I need a USB flash disk? Why is that?
W: Well, [5]because so many students use the computers, all the information on the hard drives is deleted at the end of the day. So, you’ll need a USB disk if you want to save any of your work.
M: OK, I think I’ve got that. Thank you!
