What is BOOTING

What is Booting?

Booting is the process your computer goes through when it's powered on, where it loads the operating system (like Windows, Linux, or macOS) so you can use the machine.

Boot Process (Simplified):

  1. Power On – You press the power button.
  2. POST (Power-On Self-Test) – The system checks basic hardware like RAM and CPU.
  3. BIOS/UEFI Loads – The firmware runs and looks for a bootable device (hard drive, SSD, USB, etc.).
  4. Bootloader Launches – A small program (like GRUB for Linux or Windows Boot Manager) loads the OS.
  5. Operating System Starts – The core OS files load into memory, and the login screen appears.

Types of Booting:

  • Cold Boot – Turning on a computer from a powered-off state.
  • Warm Boot – Restarting the computer without turning it off (e.g., pressing Ctrl+Alt+Del).
  • Network Boot – Booting from a server instead of a local drive.

Peripheral device ports

Peripheral device ports are the physical interfaces on a computer or other electronic device that allow you to connect external hardware (peripherals) such as keyboards, mice, printers, storage devices, and more. Here are some common types:

1. USB Ports (Universal Serial Bus)

  • Types: USB-A, USB-B, USB-C, Micro-USB, Mini-USB
  • Used for: Keyboards, mice, flash drives, external hard drives, smartphones, etc.

2. HDMI (High-Definition Multimedia Interface)

  • Used for: Connecting monitors, TVs, projectors for video and audio output.

Measuring unit for memory

The standard measuring units for memory (digital storage) are based on bytes. Here’s a hierarchy of common memory units:

  1. Bit (b) – The smallest unit, represents 0 or 1.
  2. Byte (B) – Equals 8 bits.

From there, memory is measured in multiples of bytes:

  • Kilobyte (KB) = 1,024 bytes
  • Megabyte (MB) = 1,024 KB
  • Gigabyte (GB) = 1,024 MB
  • Terabyte (TB) = 1,024 GB
  • Petabyte (PB) = 1,024 TB
  • Exabyte (EB) = 1,024 PB
  • Zettabyte (ZB) = 1,024 EB
  • Yottabyte (YB) = 1,024 ZB

Note: In some contexts, especially in marketing, 1 KB = 1,000 bytes (decimal system), but in computing, binary measurement (1 KB = 1,024 bytes) is more accurate.

Memory in Computer

Memory in a computer refers to the hardware components that store data temporarily or permanently for use by the processor and other system components. It allows the computer to access and use information quickly.

There are two main types of computer memory:


1. Primary Memory (Main Memory)

  • Volatile (data is lost when power is off)
  • Fast access
  • Used by the CPU to run programs and processes.

Examples:

  • RAM (Random Access Memory): Temporarily holds data and programs being used.
  • Cache Memory: Very fast memory close to the CPU, stores frequently used data.

2. Secondary Memory (Storage)

  • Non-volatile (data stays even when power is off)
  • Slower than primary memory
  • Used for long-term storage.

Examples:

  • Hard Drive (HDD)
  • Solid-State Drive (SSD)
  • USB Flash Drives
  • Optical Discs (CD/DVD)

Summary:
Computer memory is essential for storing data and instructions. Primary memory is fast and temporary, while secondary memory is slower but permanent.

What is ROM

ROM stands for Read-Only Memory. It's a type of non-volatile memory used in computers and other electronic devices.

Key Features of ROM:

  • Non-volatile: It retains data even when the power is turned off.
  • Read-only: Data is written during manufacturing (or in some cases, later), but it typically can't be modified or erased by the user.
  • Used to store firmware: This includes software that boots up a device or performs essential low-level operations.

Types of ROM:

  1. Masked ROM – Programmed during the manufacturing process.
  2. PROM (Programmable ROM) – Can be programmed once after manufacturing.
  3. EPROM (Erasable PROM) – Can be erased using UV light and reprogrammed.
  4. EEPROM (Electrically Erasable PROM) – Can be erased and rewritten electrically.

Common Uses:

  • BIOS in PCs
  • Embedded systems
  • Game cartridges
  • Microcontrollers


What is RAM

RAM stands for Random Access Memory. It's a type of computer memory that is used to store data and programs that are currently being used by your device.

Key Points:

  • Volatile: RAM only holds data while the device is on. When you turn it off, everything in RAM is lost.
  • Fast: RAM is much faster than storage (like hard drives or SSDs), which makes it ideal for temporary tasks.
  • Used for:
    • Running apps and programs
    • Loading operating system functions
    • Browsing the internet
    • Playing games

Example:

When you open a web browser or a game, it loads into RAM so your computer can access and run it quickly.

More RAM generally means your device can handle more apps at once and run faster.

Computer Number System

A computer number system is a way to represent numbers in a form that computers can understand and process. There are four main types of number systems commonly used in computing:


1. Binary Number System (Base-2)

  • Digits Used: 0, 1
  • Example: 1011 (Binary for decimal 11)
  • Usage: Internal computer processing; all data is represented in binary (on/off, true/false, 1/0)

2. Decimal Number System (Base-10)

  • Digits Used: 0 to 9
  • Example: 234 (Standard number system we use daily)
  • Usage: Human-readable format; used in programming output and input

3. Octal Number System (Base-8)

  • Digits Used: 0 to 7
  • Example: 17 (Octal for decimal 15)
  • Usage: Sometimes used in computing, especially in older systems and Unix file permissions

4. Hexadecimal Number System (Base-16)

  • Digits Used: 0 to 9, A (10) to F (15)
  • Example: 1A3 (Hex for decimal 419)
  • Usage: Used in programming, memory addresses, and color codes in web design

Conversion Between Systems

  • Computers often convert numbers between binary, decimal, octal, and hexadecimal for various operations.
  • Example: Decimal 255 = Binary 11111111 = Octal 377 = Hex FF

Computer Memory Units

Computer memory is measured using a hierarchy of units that reflect increasing sizes of data. Here are the most common memory units, from smallest to largest:

  1. Bit (b) – The smallest unit of data in computing; represents a binary value of 0 or 1.

  2. Byte (B) – 8 bits. Represents a single character, such as a letter or number.

  3. Kilobyte (KB) – Approximately 1,024 bytes (2¹⁰ bytes).

  4. Megabyte (MB) – Approximately 1,024 KB, or 1,048,576 bytes.

  5. Gigabyte (GB) – Approximately 1,024 MB, or 1,073,741,824 bytes.

  6. Terabyte (TB) – Approximately 1,024 GB, or 1,099,511,627,776 bytes.

  7. Petabyte (PB) – Approximately 1,024 TB.

  8. Exabyte (EB) – Approximately 1,024 PB.

  9. Zettabyte (ZB) – Approximately 1,024 EB.

  10. Yottabyte (YB) – Approximately 1,024 ZB.

How can make LAN Cable

To make a LAN (Ethernet) cable, you'll need some tools and components. Here's a step-by-step guide for making a Cat5e or Cat6 Ethernet cable with RJ45 connectors:


What You Need:

  1. Ethernet cable (Cat5e, Cat6, etc.)
  2. RJ45 connectors (8P8C plugs)
  3. Crimping tool
  4. Cable stripper or utility knife
  5. Cable tester (optional, for testing after crimping)

Wiring Standards:

There are two common wiring standards:

  • T568A
  • T568B (most commonly used)

T568B Color Order (from pin 1 to 8):

  1. White-Orange
  2. Orange
  3. White-Green
  4. Blue
  5. White-Blue
  6. Green
  7. White-Brown
  8. Brown

Steps to Make the Cable:

  1. Cut the Cable to the desired length.

  2. Strip the Outer Jacket

    • Use the cable stripper to remove about 1 inch (2.5 cm) of the outer insulation.
    • Be careful not to cut the inner wires.
  3. Untwist the Wire Pairs and straighten them.

  4. Arrange the Wires in the correct color order (T568B is recommended).

  5. Trim the Wires Evenly to about 1/2 inch (1.3 cm) in length.

  6. Insert Wires into the RJ45 Connector

    • Make sure the clip is facing down.
    • Each wire should slide into its channel inside the plug.
  7. Crimp the Connector

    • Insert the connector into the crimping tool and squeeze firmly.
  8. Repeat on the Other End

    • Use the same wiring standard (usually T568B) unless you are making a crossover cable.
  9. Test the Cable

    • Use a cable tester to ensure all connections are correct.
