The C programming language was developed to create the second UNIX version. 14. On what kind of computer was the first UNIX operating system written? A. It was written on a minicomputer, a Digital Equipment Corporation PDP-7.
A user has opened a word processor, typed the numbers123456789, and stored the document as a file called report1. Which of the following determines, in part, what bits the computer stores in the file to represent the text typed into the report? d. The binary equivalent of decimal 123456789 7. A user has opened a calculator application, typed the numbers 123456789, and then done some math problem using this number Which of the following determines, in part, what bits the computer stores in RAM to represent the number123456789? d. the binary equivalent of decimal 123456789 8.
In 1994 the public began to notice a flaw. Flaws are not uncommon in complicated integrated circuits, and most of them go unnoticed by the user, however, the Pentium flaw was very different. The nature of the flaw was in the floating point math subsection of the Pentium microprocessor, it caused incorrect answers when preforming double-precision arithmetic. In October of 1994 a man named Thomas Nicely, a mathematics professor at Lynchburg collage in Virginia was the first to notice this flaw. He found that the results of some of his calculations were incorrect.
However with the flaw, the result of the calculation was 4,195,579” (Crothers, 1994). Intel originally denied that there was even a flaw. Only after it become clear to the public that there was actually a flaw, did they acknowledge there was a flaw but it was a small and insignificant. They would only replace it if the user could prove that they needed an unflawed processor. This caused IBM to immediately stop all sales of their computers that featured the Pentium chip, forcing Intel to agree to replace all flawed microprocessors with the new unflawed version, but only upon request.
The operating system loads itself into memory and begins managing the resources available on the computer. It then provides those resources to other applications that the user wants to execute. * A task scheduler * A memory manager * A disk manager * A network manager * Other I/O services manager * Security manager The Linux kernel, created by Linus Torvalds, was made available to the world for free. Because it is free and runs on PC platforms, it gained a sizeable audience among hard-core developers very quickly. Linux has a dedicated following and appeals to several different kinds of people: * People who already know UNIX and want to run it on PC-type hardware * People who want to experiment with operating system principles * People who need or want a great deal of control over their operating system * People who have personal problems with Microsoft * In general, Linux is harder to manage than something like Windows, but offers more flexibility and configuration options.

Unit 5 Analysis 1: Pentium Flaw The Pentium flaw was a flaw in a microprocessor that caused incorrect calculations on certain common equations. This caused many people to have issues with doing calculations on their PC. It became public in 1994 when a university researcher was performing calculations and discovered several calculations were being performed incorrectly by his PC while doing double-precision arithmetic. Intel’s initial response was denying that there was a problem, but after enough people said there was a problem, they changed their statement to say that there was indeed a problem, but that it was a small problem that wouldn’t affect many people. Many of Intel’s customers were not satisfied by this answer, and started wanting their chips replaced.
The sequence is beep – pause – beep beep beep – pause – beep – pause – beep beep beep. What error is indicated by this beep sequence? Task 1 for AMI BIOS 6 short beeps means Gate A20 failure-The keyboard controller IC has failed, which is not allowing Gate A20 to switch the processor to protected mode. Replace the keyboard controller- Test keyboard- keyboard not working correctly upon testing- replaced keyboard controller-rechecked – see if it boots up now – Preventative measures-??? Maybe don’t eat or drink at work station anymore.
