off –so it can represent only two numeric values. To a computer‚ when a switch is off‚ it represents a 0; when a switch is on‚ it represents a 1. Because there are only two values‚ computers are said to function in base 2‚ which is also known as the binary number system. Computer process data by: recording‚ analyzing‚ sorting‚ summarizing‚ calculating‚ and sorting data. Then data processing system take raw date as input to produce information as output. Conclusion Data is the lowest level of knowledge

Activity 2.3.1 Hexadecimal and Octal Number Systems Introduction We all know that digital electronics use the binary number system. However‚ with new computers containing 32‚ 64‚ and even 128 bit data busses‚ displaying numbers in binary is quite cumbersome. For example‚ a single piece of data on a 64-bit data bus would look like this: 0110100101110001001101001100101001101001011100010011010011001010 Obviously‚ presenting data in this form would invite error. For this reason we use the hexadecimal

the amplitude of a constant width‚ constant-position pulse is varied according to the amplitude of the sample of the analog signal. Pulse Code Modulation (PCM) In this method‚ the analog signal is sampled and then converted to a serial n-bit binary code for transmission. Each code has the same number of bits and requires the same length of time for transmission. Graph of each Pulse Modulation Method Uses

telling a computer what operations is to perform‚ is called Programming language. It is categorized into three types as under. Machine language: (Low Level Language) Computer has its own unique machine language to perform specific tasks. It is based on binary codes 0s and 1s to execute given instructions. All instructions in machine language consists of series of 0s and 1s. It is very difficult to write program in machine language.
