Overflow is a classic example of the type of problems we encounter by mapping an infinite world onto a finite machine. No matter how many bits we allocate for a number, there is always the potential need to represent a number that doesn’t fit. How overflow problems are handled varies by ...
4. Bits & Bytes: 1 byte = 8 bits ;bit只存储1或0的信息(*),8个为一组,组成的一个Byte有256种排列组合方式(也即:取值范围),0-255,所以之前课上图片的示例中,像素的取值范围最高到255,一个byte为单位进行数据存储。(*教授生动的举例视频1分20秒:Course | edX) 5. 计算机数据计量单位:KB-->MB--...
有一个专门处理真假的数学分支的存在,已经解决了所有法则和运算:布尔代数(Boolean Algebra),在布尔代数中,变量true和false进行逻辑操作。 三个基本操作:NOT:翻转布尔值 AND OR 将晶体管类比为水龙头,gate是控制水流的龙头 在not中我们将上面看做输出,左侧看做输入 and gate 为两个二极管串联 or gate: 有两个输入...

Computer Sciencean Overview(10thedition) Chapter1Data Storage(贮存,仓库) In this chapter, we consider topicsassociated(有关,联系,联合)with data representation and thestorage of data within a computer. Thetypes of data we will consider includetext, numeric values, images, audio, andvideo. Much of...
If you're aworking software developer, which bits of computer science are useless? Which are useful? Andwhich ones are superpowers? Every episode I talk to working developers from all different backgrounds about topics in computer science. From different data structures, algorithms, analysis, paradi...
Notice that although the memory is 32 bits (4 bytes) wide, each byte has its own address. Also, more bytes (232) can be addressed, since addresses are 32 bits wide. In the 68000 memory, a 16-bit word is defined as two consecutively numbered bytes, and a 32-bit long word is four...
In order to store numbers larger than 1, bits are combined into larger units. For instance, using two bits, it is possible to represent any number between zero and three. This is shown in Table 1.1. When stored in the computer, all data is simply a string of binary digits. There is ...

Quantum computers have the potential to completely transform data science. They also have the potential to accelerate the development of artificial intelligence, virtual reality, big data, deep learning, encryption, medicine and more. The downside is that quantum computers are currently incredibly difficu...
