Binary arithmetic is simpler to learn because binary number system deals with only two digits - 0 and 1. Binary number perform all arithmetic operation such as Addition, Substraction, Multiplication and compliment as in decimal number system. Binary Addition The addition table for binary arithmetic consist of only the following four entries: 0+0=0 0+1=1 1+0=1 1+1=0 , plus a carry of 1 to the next column. 1011 + 1100 10111 1100 + 1100 11000 Binary Substraction There are three ways to do substraction between binary numbers:- 1. Simple Substraction 2. Substraction using 1's Complement 3. Substraction using 2's Complement Simple Substraction: The complete table of binary substraction is as follows: 0-0=0 0-1=1, borrow 1 from next column 1-0=1 1-1=0 1101 - 0101 1000 1001 - 0111 0...
Computer Generations Computers have evolved over time through different generations, each marked by significant technological advancements and changes in design and architecture. These generations are often categorized based on the underlying hardware and the key developments that distinguish one Generation from another. Let's explore the main computer generations: First Generation Computers The First Generation of computers refers to the initial period of electronic computing, characterized by the use of vacuum tubes as the primary electronic component. This Generation spans the 1940s and 1950s and is marked by groundbreaking developments in computer technology. Examples of First-Generation Computers: o ENIAC (Electronic Numerical Integrator and Computer): Completed in 1945, ENIAC was one of the first electronic general-purpose computers. It was designed to calculate artillery firing tables for the United States Army during World War ...
