1. In a multiprogramming and time sharing environment‚ several users share the system simultaneously. This situation can results in various security problems. a. What are the two such problems? Ans: The two problems in Multiprogramming and time sharing environment are Stealing or copying a user’s files; Writing over another program’s (belonging to another user or to the OS) area in memory; Using system resources (CPU‚ disk space) without proper accounting; Causing the printer to mix output by

The Universal Serial Bus (USB) The Universal Serial Bus (USB) is a device that was created to standardize the connection types of computer peripherals‚ such as the keyboard and mouse‚ which traditionally had their own ports which they were plugged into. The USB was created in the mid 1990’s ‚ with an official release of the “USB 1.0” in January 1996 and since then the design has been improved as well as other types of USB connections available‚ such as type A and B‚ Mini A and Mini B‚ as

A few synonyms for cognition are perception‚ insight‚ and reasoning; overall‚ diversity has a positive effect on a group’s decision-making process. Three cognitive outcomes of diversity are an improved critical thinking and decision-making process; an expanded network of resources for the group; and‚ a stronger communication structure (Griffith & Dunham‚ 2015). Our text explains that group diversity improves task performance and goal orientation. Ethnic and nationality diversity is a positive cognitive

idea from task 3‚ this one uses an interrupt to further improve and optimise the code so it can as efficient as possible. An interrupt is used when you want to quickly get the chips (CPU) attention at hardware level for a short amount of time when the value set has been meet (this is great as this removes barriers as stated on matrixtsl.com‚ you can with your program wake the controller when it’s in a low power state which you can’t do at software level). An interrupt works when you are running a program
