I want to include sound files with a presentation I’m making. How can I determine the size of the sound files before actually recording them? To calculate the approximate size for an 8-bit, monoaural, (i.e., not stereo) file, use this formula: (number of seconds of audio) x (sample rate in kHz) = file size in Kbytes For example, 7-seconds of audio recorded at 11 kHz would require approximately 77 Kbytes of disk space. If you’re recording in stereo, you need to double the file size. Likewise, using 16-bit sampling doubles the file size again. So the same 7-seconds of audio recorded at 16-bit stereo at 44 kHz would take approximately 1.2 megabytes! ((((7 seconds) x 44) x 2) x 2) = 1,232 Kbytes —Mary A. Griffin, CRC I’m confused about the various IDs and passwords I need on PennNet and the Internet. You and many other people! Penn’s network-based services are housed on various computers, more or less analogous to offices in a protected complex; the complex and each electronic service have their own levels and types of security. Your PennNet ID and password are analogous to the key that lets you enter the complex. The PennNet computer then checks its database to verify that you are a bona fide member of the Penn community. Once you’re “in,” you can access specific services on other computers at Penn. Additional IDs and passwords may be required for these computers, just as keys may be required for individual offices. The Library’s catalog, Franklin, requires no further verification of your identity, while mail services, such as those on mail.sas.upenn.edu and dolphin.upenn.edu, require their account-holders to enter a login (user) ID and password. When you set up an account for a service such as e-mail, you can make your ID and password identical to your PennNet ID and password if the system permits, or you may have to choose a different ID and password. The Library databases, such as PsychInfo and the OED, don’t require you to set up an account but you must enter your Q A & SSN to verify eligibility when you access them. Still other services require you to enter “guest” as your user ID and your e-mail address as the password. Your PennNet ID and password are also your keys to the worldwide Internet, which is a set of interconnected networks including PennNet. As with Penn services, the services (databases, libraries, etc.) on other Internetconnected computers may require additional IDs or passwords. —Edda Katz, ISC Communications Recently, I accidentally deleted some important files in my root DOS directory. How can I prevent that from happening in the future? The easiest way to protect important files is to make copies of them and save them in a special subdirectory set up to protect against accidental erasure. Many of the files in your root DOS directory should be protected this way. To copy the most important files in five easy steps, follow these instructions: 1 First go to the C: prompt and make sure that you are in the root directory by typing CD\ 2 Now type MD DIRECTORYNAME (Note: replace DIRECTORYNAME with a name appropriate for your special subdirectory in the line above and in the commands below. Good choices might be SPECIAL or PROTECT) 3 Type COPY *.BAT C:\DIRECTORYNAME 4 Next, type COPY C:\WINDOWS\*.INI C:\DIRECTORYNAME 5 Finally, type COPY C:\WINDOWS\SYSTEM\*.INI C:\DIRECTORYNAME You will now have copies of your most important DOS and Windows system files in the directory that you created. If you accidentally delete an important file, you will be able to restore it from the copy in your new subdirectory. You should periodically go through the steps above to update your copies so that they remain current. —Joseph R. Harris, CRC APRIL 1995 31
