    Study Notes

    Processors

    • Multi-core processor, quad-core processor, and dual-core processor are types of processors.
    • There is no such thing as a "primary-core processor".

    CPU

    • The clock speed of CPU is measured in Giga Hertz.

    System Software

    • System software is designed to control the operations of a computer.

    Motherboard

    • The motherboard is the main circuit board of the system unit.

    Hardware

    • Printer, Scanner, and Monitor are examples of hardware.
    • Interpreter is not an example of hardware.

    Programming Languages

    • Machine language is a computer language that is written in binary codes only.
    • A Source Program is the program written by the programmer in high-level language.
    • An Assembler is used as a translator for low-level language.

    Flowcharts

    • A diamond-shaped box in a flowchart is used to denote a decision.

    System Development

    • SDLC stands for Software Development Life Cycle.

    Computer Types

    • A desktop computer is also known as a PC.

    Data Processing

    • The basic goal of computer processing is to convert data into information.
    • The process of carrying out commands is called Executing.

    Networks

    • Servers are computers that provide resources to other computers connected to a network.

    Data Measurement

    • The smallest unit of data in a computer is a Bit.
    • 1 GB (Gigabyte) is equal to 1024 MB (Megabytes).
    • 1 MB is equal to 1024 KB (Kilobytes).

    Memory

    • SRAM is used in cache memory.
    • ROM types include PROM and EPROM.

    Processor Components

    • The Arithmetic and Logic Unit (ALU) is the 'heart' of the processor, performing many different operations.
    • The Control Unit directs and coordinates most of the operations in the computer.

    Computer Components

    • Projectors are an example of an Output device.
    • The physical parts of a computer are referred to as Hardware.

    Ram

    • RAM (Random Access Memory) is memory that can be both read and written.

    Storage Devices

    • Hard disk drives, floppy disk drives, and CD drives are all examples of storage devices.
    • Printers are not an example of a storage device.

    Computer Types

    • Supercomputers are the most powerful type of computer, performing complex calculations extremely rapidly.

    • Application Software is designed to perform a specific task.
    • OSS stands for Open Source Software.
    • A Programmer is a person who designs the programs in a software package.

    Data Processing

    • Data is the raw material used as input, and Information is the processed data obtained as output.

    System Software

    • System software includes BIOS software, Unix, and Linux.
    • Microsoft Word is an example of Application Software, not System Software.

    Mainframes

    • A mainframe is a large, expensive, powerful computer that can handle hundreds or thousands of connected users simultaneously.

    Coding Systems

    • ASCII code is an international coding system for text-based data that uses an 8-bit pattern.
