You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 44.201.0.0/16 has been blocked (disabled) by ‪ST47‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider. To prevent abuse, web hosts may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a web host's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and they should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 23:54, 31 July 2024.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

The '''David R. Cheriton School of Computer Science''' is a professional school within the  [[University of Waterloo Faculty of Mathematics|Faculty of Mathematics]] at the [[University of Waterloo]]. QS World University Rankings ranked the David R. Cheriton School of Computer Science 24th in the world, 10th in [[North America]] and 2nd in Canada in [[Computer science|Computer Science]] in 2014.<ref name="QS World University Rankings">[http://www.topuniversities.com/university-rankings/university-subject-rankings/2014/computer-science-information-systems#sorting=rank+region=+country=+faculty=+stars=false+search=], QS World University Rankings</ref> ''U.S. News & World Report'' ranked the David R.

==History==
In 1965, when [[Mathematics]] was still a department within the [[University of Waterloo Faculty of Arts|Faculty of Arts]], four third-year mathematics students (Richard Shirley, Angus German, [[James G. Mitchell]], and Bob Zarnke) wrote the [[WATFIV (programming language)|WATFOR]] compiler for the [[FORTRAN]] programming language, under the direction of lecturer Peter Shantz. "Within a year it would be adopted by computing centres in over eight countries, and the number of student users at UW increased to over 2500." Later on in 1966, two mathematics lecturers ([[Paul Dirksen]] and [[Paul H. Cress]]) led a team that developed WATFOR 360, for which they received the 1972 [[Grace Murray Hopper Award]] from the [[Association for Computing Machinery]].

UW's [[University of Waterloo Faculty of Mathematics|Faculty of Mathematics]] was later established in 1967.  As a result, the ''Department of Applied Analysis and Computer Science'' (AA&CS) was created.  By 1969, AA&CS had become the largest department in the faculty.  At that point, the first two PhD degrees in computer science were awarded, to Byron L. Ehle, for a thesis on [[numerical analysis]], and to Hugh Williams, for a thesis on [[computational number theory]].  In 1975 the department dropped the words "Applied Analysis" and became simply the ''Department of Computer Science''.

In 1982, the Institute for Computer Research (ICR) was established. Its goals were "to foster computer research..., facilitate interaction with industry, and encourage advanced education in computer science and engineering." Also that year, the Ontario government announced plans to build the [[Davis Centre]], current home of the School of Computer Science. The groundbreaking was in April 1985 and the Davis Centre was formally dedicated on November 10, 1988.

On May 1, 2002, the department officially became the ''School of Computer Science''. On November 18, 2005, it was renamed again to the ''David R. Cheriton School of Computer Science'', in recognition of the establishment of the [[David Cheriton|David R. Cheriton]] Endowment for Excellence in Computer Science. Cheriton had recently donated $25 million to the university.

Support for computing within the School of Computer Science had been historically provided by the Computer Science Computing Facility (CSCF) and ICR.

==Programs==
The David R. Cheriton School of Computer Science offers several diverse undergraduate programs including:
* [[Bachelor of Computer Science]]
** Honours Computer Science
*** Business Option
*** [[Bioinformatics]] Option
*** Digital Hardware Option
*** Software Engineering Option
** Honours Data Science
* [[Bachelor of Mathematics]]
** Honours Computer Science
*** Business Option
*** Digital Hardware Option
* [[Bachelor of Software Engineering]]
* [[Bachelor of Computing and Financial Management]]

In general, the philosophy of the undergraduate program is to build a solid foundation of mathematics and computer science during the first three years of the program, allowing students more flexibility in fourth year. Required courses for all computer science programs include courses in combinatorics, data structures, algorithms, compilers, software engineering and operating systems. The curriculum is also designed to encourage either significant depth in an area outside of computer science (such as in the Bioinformatics Option) or exposure to a variety of areas outside of the computer science.

The school also offers Masters of Mathematics and Ph.D. graduate programs.
* Master of Mathematics (Computer Science)
* Ph.D. in Computer Science

==Reputation==
The university is well-regarded in the field of Computer Science, where it ranks 41st in the world and fourth in Canada according to the [[Times Higher Education World University Rankings]], and 22nd in the world and second in Canada in the [[QS World University Rankings]] in 2019.<ref>((cite web|url=https://www.timeshighereducation.com/world-university-rankings/2019/subject-ranking/computer-science#!/page/0/length/25/locations/CA/sort_by/rank/sort_order/asc/cols/stats|title=World University Rankings 2019 by subject: computer science|year=2019|publisher=Times Higher Education|work=Times Higher Education World University Rankings|accessdate=28 June 2019))</ref><ref>((cite web|url=https://www.topuniversities.com/university-rankings/university-subject-rankings/2019/computer-science-information-systems|title=Computer Science & Information Systems Rankings 2019|year=2018|publisher=QS Quacquarelli Symonds Limited|work=QS Top Universities|accessdate=28 June 2019))</ref>
