  • The Hexadecimal Number System and Memory Addressing
    C5537_App C_1107_03/16/2005 APPENDIX C The Hexadecimal Number System and Memory Addressing nderstanding the number system and the coding system that computers use to U store data and communicate with each other is fundamental to understanding how computers work. Early attempts to invent an electronic computing device met with disappointing results as long as inventors tried to use the decimal number sys- tem, with the digits 0–9. Then John Atanasoff proposed using a coding system that expressed everything in terms of different sequences of only two numerals: one repre- sented by the presence of a charge and one represented by the absence of a charge. The numbering system that can be supported by the expression of only two numerals is called base 2, or binary; it was invented by Ada Lovelace many years before, using the numerals 0 and 1. Under Atanasoff’s design, all numbers and other characters would be converted to this binary number system, and all storage, comparisons, and arithmetic would be done using it. Even today, this is one of the basic principles of computers. Every character or number entered into a computer is first converted into a series of 0s and 1s. Many coding schemes and techniques have been invented to manipulate these 0s and 1s, called bits for binary digits. The most widespread binary coding scheme for microcomputers, which is recog- nized as the microcomputer standard, is called ASCII (American Standard Code for Information Interchange). (Appendix B lists the binary code for the basic 127- character set.) In ASCII, each character is assigned an 8-bit code called a byte.

  • Bits and Bytes
    BITS AND BYTES To understand how a computer works, you need to understand the BINARY SYSTEM. The binary system is a numbering system that uses only two digits—0 and 1. Although this may seem strange to humans, it fits the computer perfectly! A computer chip is made up of circuits. For each circuit, there are two possibilities: An electric current flows through the circuit (ON), or An electric current does not flow through the circuit (OFF) The number 1 represents an “on” circuit. The number 0 represents an “off” circuit. The two digits, 0 and 1, are called bits. The word bit comes from binary digit: Binary digit = bit Every time the computer “reads” an instruction, it translates that instruction into a series of bits (0’s and 1’s). In most computers every letter, number, and symbol is translated into eight bits, a combination of eight 0’s and 1’s. For example the letter A is translated into 01000001. The letter B is 01000010. Every single keystroke on the keyboard translates into a different combination of eight bits. A group of eight bits is called a byte. Therefore, a byte is a combination of eight 0’s and 1’s. Eight bits = 1 byte Capacity of computer memory, storage such as USB devices, DVD’s are measured in bytes. For example a Word file might be 35 KB while a picture taken by a digital camera might be 4.5 MG. Hard drives normally are measured in GB or TB: Kilobyte (KB) approximately 1,000 bytes MegaByte (MB) approximately 1,000,000 (million) bytes Gigabtye (GB) approximately 1,000,000,000 (billion) bytes Terabyte (TB) approximately 1,000,000,000,000 (trillion) bytes The binary code that computers use is called the ASCII (American Standard Code for Information Interchange) code.

This is called a base-10, or decimal system. Binary code, however, uses only zeros and ones in a sequence of eight spots. We often to refer to these binary, or base-2, digits as “bits.” Binary code is used to communicate information between computers, communication devices, and many more modern technologies. It’s useful to build into electronic devices because it is a simple system that requires something turn on or off (where 1 is the on state and 0 is the off state).

  • Machine and Assembly Language Programming
    COURSE TITLE: FOUNDATIONS OF SEQUENTIAL PROGRAM CODE: CSC 206 TOPIC TWO Machine language, assembly language and assemblers, low/high level languages (Machine-level implementation of high-level language) Objectives By the end of this class, students should be able to: 1. describe computer/programming language 2. list and describe the three different types or levels of programming languages 3. list the advantages of programming languages 4. list the disadvantages of programming languages 5. list and describe the different examples of types or levels of programming languages DISCLAIMER The contents of this document are intended for leaning purposes at the undergraduate level. The materials are from different sources including the internet and the contributors do not in any way claim authorship or ownership of them. COMPUTER / PROGRAMMING LANGUAGES Computer or Programming Languages are sets of words, symbols and codes used to write programs. Different programming languages are available for writing different types of programs. Some languages are specially used for writing business programming, others are used for writing scientific program etc. There are three types or levels of computer programming: 1. Machine language 2. Low level Languages 3. High Level Languages Machine language Machine Language is the actual bits used to control the processor in the computer, usually viewed as a sequence of hexadecimal numbers (typically bytes). The processor reads these bits in from program memory, and the bits represent "instructions" as to what to do next. Thus machine language provides a way of entering instructions into a computer (whether through switches, punched tape, or a binary file). Machine Language instruction has two (2) parts.

What’s happening? Computer programmers use a special language to program computers and robots. This language of 0’s and 1’s is called binary code; binary, meaning “two numbers”. Coding is a step by step guide for a computer to accomplish a task. Binary coding uses millions of patterns of 0’s and 1’s to signal off and on switches for electrical signals inside the computer, allowing the computer to perform different functions. In this code, each letter is represented by a set of eight digits. Each digit is called a bit. Each set of eight digits is called a byte.

Starting from left to right, write the numbers 16, 8, 4, 2, and 1 on your fingers. Since you traced your right hand, your thumb will be number 16 and your little finger will be marked with the number one. 2.Hold up your left hand with your palm facing you (the order of your fingers should match the order of your handprint you drew in Step 1). I chose to have my palm facing us because it was easier to manipulate our fingers for the exercise. 3.Now, you can use your hand and the numbers you wrote on your paper to add up to the number 31 (in decimal numbers), which is the max for 5-bit binary code strings. Since we are working with the English alphabet, we are going to focus up to the number 26 because there are 26 letters in the alphabet.

Number System A number system relates quantities and symbols.In digital system how information is represented is key and there are different radices, i.e. number bases, that a numbering system can use. 1.1 Digital computer Any class of devices capable of solving problems by processing information in discrete form.It operates on data,including letters and symbols,that are expressed in binary form i.e using only two digits 0 and 1. The block diagram of digital computer is given below: Processor (or) Control Unit Arithmetic unit Storage (or) Memory Unit Input Output Devices and Devices and Control Control The memory unit stores programs as well as input, output and intermediate data. The processor unit performs arithmetic and other data processing tasks as specified by the program.The control unit supervises the flow of information between various units. The program and data prepared by the user are transferred into the memory unit by means of an input device such as punch card reader (or) tele typewriter. An output device, such as printer, receives the result of the computations and the printed results are presented to the user. 1.2 Number Representation: It can have different base values like: binary (base-2), octal (base-8), decimal (base 10) and hexadecimal (base 16),here the base number represents the number of digits used in that numbering system.
