Introduction to Microprocessor

 .

A microprocessor is a small, compact semiconductor device that performs the functions of a computer's Central Processing Unit (CPU) on a single chip. It processes instructions from programs and manage the operations of the computer's hardware.

Features of Microprocessors:

  • Central Processing Unit (CPU) Functions:
    • Arithmetic Logic Unit (ALU): Performs arithmetic and logical operations such as addition, subtraction and logical comparisons.
    • Control Unit (CU): Directs the operation of the processor by fetching, decoding and executing instructions from memory.
    • Registers: Small, high-speed storage locations within the CPU that temporarily hold data and instructions during processing.

  • Clock Speed:
    • Frequency: Measured in Hertz (Hz), it determines how many cycles per second the microprocessor can execute, Higher clock speeds generally lead to faster processing capabilities.

  • Instruction Set Architecture (ISA):
    • Set of Instruction: Defines the set of commands the microprocessor can execute. Common ISAs include x86, ARM, and MIPS, each with its own set of instructions and operational capabilities.
  • Cores:
    • Single-Core vs Multi-Core: Modern microprocessors often have multiple cores, allowing them to perform several tasks simultaneously, improving multitasking and overall performance.
  • Cache Memory:
    • L1, L2 and L3 Caches: Small, fast memory located within the processor to store frequently accessed data and instructions, reducing the time required to fetch them from main memory.
  • Integrated Graphics:
    • Integrated Graphics Processing Unit (GPU): some microprocessors include a built-in GPU, allowing for efficient handling of graphics and video tasks without needing a separate graphics card.
  • Power Management:
    • Dynamic Frequency Scaling; Techniques such as Intel's SpeedStep and AMD's Cool'n'Quiet adjust the processor's clock speed and power consumption based on workload to save energy and reduce heat.

Introduction of Computer

.  A computer is an electronic device. It take input and store the data in memory and performing the function to produce accurate result in output device. It is used to type document, send email, play game, browse the web and entertainment.   Characteristics of computer  1 . High speed  Computer is very fast device. It is capable of performing calculation of very large amount of data. The computer has unit of speed in microsecond, nanosecond and even in picosecond. The computer is capable of performing millions of tasks per second. 2. Accuracy  The computer produces highly accurate and reliable result.  It does not make any kind of mistake in calculating. The calculation are 100% error free. The computers perform accurate 'n' number of times. 3. Storage capability A computer has much more storage capability. It can store large amount of data. It can store any type of data such as image, video, text document, audio and many more. 4. Diligence Diligence ...

Introduce Linux, UNIX and Linux distribution.

 . Linux Linux is an open source operating system. The term Linux is actually referred to mean a kernel of Unix like operating system developed by a Finish software architect Linus Torvald. The name Linux is derived from Linus' Unix. Linux was originated from the inspiration of a small Unix like operating system MINIX by A.S Tanenbum. Linux is a complete multiuser, multiprocessing, secure and stable operating system which is also considered as UNIX clone. However no code from the proprietary from AT and T is included in Unix. It has flavor of Unix but is not Unix. UNIX  UNIX is a layered operating system. The innermost layer is the hardware that provides the service for the OS. The operating system, referred to in UNIX as the kernel, interacts directly with the hardware and provides the services to the user program. These user programs don't need to know anything about the hardware. They just need to know how to interact with the kernel and it's up to the kernel to provide ...
