Essay On Computer Pros And Cons

Submitted By

Pages 4
An operating system is the software that supervises a computer’s operation in storing and retrieving files, scheduling programs for execution, and coordinating the execution of programs. Each operating system has its own pros and cons. Three operating systems I will take a look at in this report are: MacOS Sierra, Ubuntu, and Windows 8.

MacOS Sierra was initially released on September 20, 2016. It is the thirteenth release of MacOS, which is Apple’s operating system for Mac computers. Sierra is preceded by OS X El Capitan and succeeded by MacOS High Sierra. It is named after the Sierra Nevada mountain range in California, the home of Apple.

Sierra has some pros to it. One pro is that it is a smooth, easy, and free upgrade from its predecessor OS X El Capitan. Sierra also performs better than El Capitan. Another pro to Sierra is that it integrated Siri, an assistant which uses user voice input to answer questions, make recommendations, and perform actions. A third pro to Sierra is that it added support for Apple Pay, a payment and digital service that lets users make secure purchases and send and receive money from others. The final pro I will mention is Sierra’s enhanced security features. One example of this is that a user can now unlock a Mac using an Apple Watch.

In addition to its pros, Sierra also has …show more content…
One con is that the upgrade from Windows 7 to Windows 8 is not free and costs $39.99 if the user is running Windows XP, Vista, or Windows 7, $119.99 if not. Another con is that Windows 8 is more susceptible to viruses and has less security than both MacOS Sierra and Ubuntu. Windows 8’s new user interface is difficult to learn and is confusing. In addition, Windows 8 introduces two separate control panels, which can cause an awful lot of confusion to the user. The final con I will mention is that Windows 8 is closed source, just like MacOS Sierra. Ubuntu, on the other hand, is totally open source and easily

First we have our routers and switches. Routers perform many functions, one of which is serving as a firewall. Computers have tens of thousands of ports, or "doors" as this essay will refer to them as. Without a firewall, all the doors on the computer are unlocked and available for anyone to use. Anyone could be your brother sending an email, or hacker from Indonesia using your computer to send SPAM. Firewall's will recognize all the doors your computer isn't using and lock them, so no one can use the doors, unless you know the password for the firewall. Routers also have various other functions, which may or may not be used by businesses; it all depends on your application. Switches take one internet connection and split it into many connections. Fore example, if you have a cable modem and you want six computers online, you will need to get six IP addresses from your ISP and use a switch to split the one incoming connection. An IP address is like a street address, one per computer or connection to the internet. Switches can also be used as device for connecting...

The Role O Br

...take the same class simultaneously. Is this the future of college? Nathan Heller wrote about the phenomenon in the May 20, 2013 issue of The New Yorker in "Laptop U." I recommend you find a copy or subscribe online for the full article, but I'll share with you here what I gleaned as the pros and cons of MOOCS from Heller's article. What Is a MOOC? The short answer is that a MOOC is an online video of a college lecture. The M stands for massive because there is no limit to the number of students who can enroll from anywhere in the world. Anant Agarwal is a professor of electrical engineering and computer science at MIT, and president of edX, a non-profit MOOC company owned jointly MIT andHarvard. In 2011, he launched a forerunner called MITx (Open Courseware), hoping to get 10 times the usual number of classroom students in his spring-semester circuits-and-electronics course, about 1,500. In the first few hours of posting the course, he told Heller, he had 10,000 students sign up from all over the world. The ultimate enrollment was 150,000. Massive. The Pros MOOCs are controversial. Some say they are the future of higher education. Others see them as the eventual downfall of it. Here are the pros Heller found in his research. MOOCS: 1. Are free. Right now, most MOOCs are free or nearly free, a definite plus for the student. This is likely to change as universities look for ways to defray the high cost of creating MOOCs. 2. Provide a solution to overcrowding. According...

What Is Ai?

...apocalyptic societies where intelligent super-computers have either enslaved the human race or eradicated the inferior species altogether. For some, the connotation of "artificial intelligence" attacks the very core of the human spirit, the pride of our race. The very thought of an "intelligent" computer that is on par, or more likely superior, to our own brain sends chills down the spine. Are these concerns realistic? Or are they unfounded worries of people who don't understand the issue? Some proponents of artificial intelligence insist that such concerns are the result of semantic misunderstanding. By definition, Artificial Intelligence (AI) is the area of computer science focusing on creating machines that can engage on behaviors that humans consider intelligent ("Artificial Intelligence”, Herzfeld Noreen). The ability to create intelligent machines has intrigued humans since ancient times and today with the advent of the computer and 50 years of research into AI programming techniques, the dream of smart machines is becoming a reality (Nonlinear Science and Complexity, M. Marques). Researchers are creating systems which can mimic human thought, understand speech, beat the best human chess player, and countless other feats never before possible.
