He noted that "very smart people" had to go down the "dead ends" of mechanical computers and decimal computing before reaching a scalable solution—namely, the electronic, binary computer with a von Neumann architecture. The book also covers more recent developments, including topics like floating point math, operating systems, and ASCII.
An accompanying book, The Computer Book, was commissioned by the BBC to tie in with the series, [4] giving an introduction to microcomputers and general computing. Its content covers the basics of the history of computing , programming languages , debugging , logic programming , semiconductor memory , printing , ADCs / DACs , flowcharts , as ...
Machine code is the form in which code that can be directly executed is stored on a computer. It consists of machine language instructions, stored in memory, that perform operations such as moving values in and out of memory locations, arithmetic and Boolean logic, and testing values and, based on the test, either executing the next instruction in memory or executing an instruction at another ...
In computer science, a logical shift is a bitwise operation that shifts all the bits of its operand. The two base variants are the logical left shift and the logical right shift . This is further modulated by the number of bit positions a given value shall be shifted, such as shift left by 1 or shift right by n .
Computer science GCSE and A levels have been made more rigorous. From around 2014 the new Computing GCSE has been taken. In November 2018 the government-funded National Centre for Computing Education was founded at the University of York , to coordinate training for computing teachers in England.
Prentice Hall International Series in Computer Science was a series of books on computer science published by Prentice Hall. [1] The series' founding editor was Tony Hoare.
