Computer science is the scientific and practical approach to computation and its applications. It is the systematic study of the feasibility, structure, expression, and mechanization of the methodical procedures (or algorithms) that underlie the acquisition, representation, processing, storage, communication of, and access to information. An alternate, more succinct definition of computer science is the study of automating algorithmic processes that scale. A computer scientist specializes in the theory of computation and the design of computational systems.
Its fields can be divided into a variety of theoretical and practical disciplines. Some fields, such as computational complexity theory (which explores the fundamental properties of computational and intractable problems), are highly abstract, while fields such as computer graphics emphasize real-world visual applications. Still other fields focus on challenges in implementing computation. For example, programming language theory considers various approaches to the description of computation, while the study of computer programming itself investigates various aspects of the use of programming language and complex systems. Human–computer interaction considers the challenges in making computers and computations useful, usable, and universally accessible to humans.
Crash Course (also known as Driving Academy) is a 1988 made for television teen film directed by Oz Scott.
Crash Course centers on a group of high schoolers in a driver’s education class; many for the second or third time. The recently divorced teacher, super-passive Larry Pearl, is on thin ice with the football fanatic principal, Principal Paulson, who is being pressured by the district superintendent to raise driver’s education completion rates or lose his coveted football program. With this in mind, Principal Paulson and his assistant, with a secret desire for his job, Abner Frasier, hire an outside driver’s education instructor with a very tough reputation, Edna Savage, aka E.W. Savage, who quickly takes control of the class.
The plot focuses mostly on the students and their interactions with their teachers and each other. In the beginning, Rico is the loner with just a few friends, Chadley is the bookish nerd with few friends who longs to be cool and also longs to be a part of Vanessa’s life who is the young, friendly and attractive girl who had to fake her mother’s signature on her driver’s education permission slip. Kichi is the hip-hop Asian kid who often raps what he has to say and constantly flirts with Maria, the rich foreign girl who thinks that the right-of-way on the roadways always goes to (insert awesomely fake foreign Latino accent) “my father’s limo”. Finally you have stereotypical football meathead J.J., who needs to pass his English exam to keep his eligibility and constantly asks out and gets rejected by Alice, the tomboy whose father owns “Santini & Son” Concrete Company. Alice is portrayed as being the “son” her father wanted.
"Want To" is a song co-written and recorded by American country music duo Sugarland. It was released in August 2006 as the first single from the album Enjoy the Ride. It was their first single not to feature former member Kristen Hall, although Jennifer Nettles had previously been featured on Bon Jovi's Number One country hit, "Who Says You Can't Go Home", the song was also the first regular Number One hit of Sugarland's career in the U.S., spending two weeks at the top of the Billboard Hot Country Songs charts in late 2006. The duo's members, Jennifer Nettles and Kristian Bush, wrote the song along with Bobby Pinson. The song has sold 856,000 copies in the US as of April 2013.
PBS Digital Studios is a YouTube channel and network through which PBS distributes original educational web video content. It comprises both original series and partnerships with existing YouTube channels. Most of the series are about science, pop culture, art, food, news, and music, though the channel originally launched with a series of video remixes based on PBS icons such as Mr. Rogers.
PBS Digital Studios founded by Jason Seiken in June 2012. They had their first viral hit with a "remix" of autotuned vocals from Mr. Rogers' Neighborhood titled "Garden of Your Mind."
The PBS Digital Studios network has received more than 500 million views and has over 7 million subscribers. Popular series found on their channels include Crash Course, Blank on Blank, It’s Okay To Be Smart, and the multiple Webby Award-winning PBS Idea Channel. Each month, the shows average more than 5 million streams.
Its first scripted series, Frankenstein, MD, launched on August 19, 2014 and ran until October 31, 2014.
"Carrie Anne" is a song written by Allan Clarke, Graham Nash, and Tony Hicks and released by British pop rock group The Hollies. The song was recorded on 1 May 1967 and was released as a single in the same month by Parlophone Records in the United Kingdom and Epic Records in the United States. It became a hit in 1967, reaching #3 on the UK Singles Chart. It was also a hit in the US and Canada, peaking at #9 on both pop charts. It also reached No.4 in the Irish charts.
Actress Carrie-Anne Moss was named (by her mother) in honor of the song, which was released three months before her birth.
According to Allan Clarke the song was written during a concert the group did with Tom Jones and the song was written mainly by Graham Nash and Tony Hicks with Allan Clarke supplying the lyrics for the middle eight. In 1995, Graham Nash revealed that he had written the song for Marianne Faithfull but was "too shy" to use her real name. The song was recorded in only two takes on 1 May 1967 at EMI's Abbey Road Studios. The first take was a false start and can be heard on the compilation The Hollies at Abbey Road: 1966 to 1970.

You should ask a lot of people for advice. In my opinion, most people in the world should get their bachelors in CS before working in the field. There's some people that can figure it out on their own, but likely most people need the school structure to learn it

So as you may have noticed from last episode, computers keep getting faster and faster, and by the start of the 1950s they had gotten so fast that it often took longer to manually load programs via punch cards than to actually run them! The solution was the operating system (or OS), which is just a program with special privileges that allows it to run and manage other programs. So today, we’re going to trace the development of operating systems from the Multics and Atlas Supervisor to Unix and MS-DOS, and take at look at how these systems heavily influenced popular OSes like Linux, Windows, MacOS, and Android that we use today.

Algorithms are the sets of steps necessary to complete computation - they are at the heart of what our devices actually do. And this isn’t a new concept. Since the development of math itself algorithms have been needed to help us complete tasks more efficiently, but today we’re going to take a look a couple modern computing problems like sorting and graph search, and show how we’ve made them more efficient so you can more easily find cheap airfare or map directions to Winterfell... or like a restaurant or something.

Take the 2017 PBS Digital Studios Survey: http://surveymonkey.com/r/pbsds2017. Today we're going to talk about a fundamental part of all modern computers. The thing that basically everything else uses - the Arithmetic and Logic Unit (or the ALU). The ALU may not have to most exciting name, but it is the mathematical brain of a computer and is responsible for all the calculations your computer does! And it's actually not that complicated. So today we're going to use the binary and logic gates we learned in previous episodes to build one from scratch, and then we'll use our newly minted ALU when we construct the heart of a computer, the CPU, in episode 7. *CORRECTION* We got our wires crossed with the Intel 4004, which we discuss later.

Hey all, I am finally back with another computer science video! More specifically, this is the Redstone Computer v4.0! This is the successor to the Redstone Computer v3.0, and it contains a lot of improvements learned from the Redstone Computer v3.0! It also adds some interesting features, such as a GPU (plotter) and the ability to change the clock speed of the computer through software! I mention this in the video as well, but thank you guys so much for 200 subscribers! Really means a lot :) Computer download (with information included): http://tinyurl.com/j363j5x Computer specs: - 8-bit architecture and interface - Variable clock speed - Four "cores" (ALUs), and each are independent of each other -- each ALU has a cache -- each ALU supports add/sub/compare/bit shift left/right/not/oth...
