    Study Notes

    Number Systems

    • PCs use the binary number system for data coding. Other systems used are octal and decimal.

    Program Control

    • The first statement of program control in computing processes was by Ch. Babbage. Other contributors include J. Mauchli, John Fon Neumann, Ada Lovelace, and Norbert Wiener.

    Byte Definition

    • A byte is a sequence of eight bits.
    • It's the unit of measure for information.
    • It represents a quantity of information as 1 or 0.
    • It groups four hexadecimal figures.

    Computer Storage

    • Computers store data, elements, algorithms, and multimedia components.

    Information Characteristics

    • Information as a message should include all relevant information. It must also be current, adequate and verifiable for accuracy, appropriateness, and validity. Information should be timely available and not obsolete. It should also be objective.

    Data Processing (Ordering)

    • Data processing methods for ordering include sorting and filtration of data. Formalization and transportation of data are also used in ordering.

    Data Processing (Compressing)

    • Data processing methods for compressing data include archiving. Filtration, sorting, and transportation are not used for compressing data.

    Maximum Number of Bits

    • 256 is the maximum number of bits that can have no more than 8 bits of information.

    Binary Equivalent

    • The binary equivalent of decimal 42 is 101010.

    Magnetic Storage Types

    • Magnetic storage comes in firm and soft, floppy and hard, and empty and filled categories. Input and output are not categories for magnetic storage.

    Random Access Memory (RAM) Acceleration

    • Cash memory is used for acceleration of access to RAM.

    BIOS Constant Memory

    • BIOS constant memory is used for checking computer equipment.

    Computer Organization Contributor

    • John von Neumann contributed to the organization of computers.

    Modem and Fax Modem

    • Modems and fax modems are used to exchange information with other computers. They are also used for conversations with users and for effective work with office equipment. They are also used in satellite communications.

    Core Speed

    • Core speed is a characteristic of information processing, not a characteristic of storage.

    Data Processing (Ordering)

    • Sorting, and filtering are used in data processing for ordering.

    Data Processing (Compressing)

    • Archiving is used for data processing in compressing data.

    Data Types in Computer

    • Data stored in computers includes data, elements, algorithms, multimedia.

    Information Characteristics

    • Information should be verifiable, adequate, current, and accessible; not obsolete, and objective rather than subjective.

    Number of bits in word

    • The word "COMPUTER" comprises eight bytes.

    Gbytes Conversion

    • 32 gigabytes comprise 235 bytes.

    Binary Conversion

    • The binary number 1001 is equal to decimal value 9.

    Binary Multiplication

    • The multiplication of binary numbers 1011 and 110 is 1000010.

    Hexadecimal Conversion

    • Converting the hexadecimal number 255 into decimal produces 597.

    Decimal to Binary Conversion

    • Decimal 2 converted to binary is 10.

    Summation of Binary Numbers

    • Adding binary numbers 111011 and 101010 yields 1100101.

    Binary Multiplication

    • Multiplying binary 110 by 111 results in 101010.

    Mathematical Coprocessor Purpose

    • Mathematical coprocessors are essential for mathematical operations in computers to assist the basic processor.

    Modem Use

    • Modems and fax modems are used for communication with users, efficient office equipment use, and connections to communications satellites.

    Coding of Data

    Which type of number coding is used by devices, to code data, that is primarily in the binary number system.

    Data Storage in the Computer

    Different types of data are stored in computer like, data, components, elements, algorithms, multimedia.
