Question of the Week

Posted on 9/16/19 4:44am

If an address bus needs to be able to address four devices, how many conductors will be required?  What if each of those devices also needs to be able to talk back to the I/O control device?


The solution of the previous question of the week can be seen below.


The maximum aggregate I/O transfer rate of the system is equal to:


700Kbystes/s + 700 Kbytes/s+ 2* 6.6 Kbytes/s+ 2* 1.2 Kbytes/s+ 10* 1Kbytes/s = 1,400 Kbytes/s+ 13.2 Kbytes/s+ 2.4 Kbytes/s+ 10 Kbytes/s= 1,425.6 Kbytes/s. This can be explained by the fact that a selector channel can’t service more than one device at a time.


You can find the solution to the current question and similar questions here.

Benefits Of Online College Homework Help To Students

Posted on 6/15/16 3:10pm

Online homework help provides a wealth of benefits for students. Perhaps the most important advantage is convenience. The 24/7 availability enables students to log in and submit assignments or participate in tutoring sessions whenever their schedule permits, from wherever they have internet access. Online tutorials also allow students to learn at their own pace without feeling the need to keep up with other students, as is often the case in a typical classroom setting. In fact, many students achieve better results when using online tutorials than when sitting in a classroom.


Getting college homework help via the Internet allows students to practice as often as they wish until they have mastered the materials. Tutors can also point out a variety of supplemental materials that students can access simply by clicking on a link, which can enhance their learning experience. Finally, online tutorials can offer a cost-effective learning solution - an important factor when one considers the significant expenses associated with higher education these days.
