Study Notes

Mainframe vs Supercomputer

Mainframe function: Primarily used for large-scale transaction processing, data storage and retrieval, and complex calculations. Businesses often use them for mission-critical applications, such as financial transactions, airline booking systems, and data warehousing.
Supercomputer processing: Supercomputers excel in massive parallel processing, solving complex problems involving scientific modeling, weather forecasting, and simulations. They are distinguished by their extremely fast processing speeds and ability to handle complex tasks requiring immense computational power.

Supercomputer Characteristics

Speed: Supercomputers are typically measured in floating-point operations per second (FLOPS), a unit representing the number of calculations performed per second.

Supercomputer Applications

Supercomputers are not commonly used for: General purpose computing, such as everyday tasks like web browsing, word processing, or light gaming.

Notable Supercomputer

Summit, a supercomputer developed by IBM, was renowned for its highest performance in November 2018.

SATA Connection Port

SATA (Serial ATA) is a common interface for connecting storage devices like hard drives and solid-state drives (SSDs) to a motherboard.

Power Fluctuations

Capacitors are used to stabilize power fluctuations and provide temporary power storage on a motherboard.

Jumpers

Jumpers on a motherboard are small electrical connectors that allow adjustments to system settings, such as determining the boot priority of connected storage devices.

CMOS Backup Battery

The CMOS backup battery is a small battery on a motherboard that keeps the CMOS configuration settings, such as boot order and date/time, active even when the computer is powered off.

Capacitor Components

Capacitors are composed of two conductive plates separated by an insulating material called a dielectric.

ATA/IDE Interface

ATA/IDE (Advanced Technology Attachment/Integrated Drive Electronics) is a connection interface used for connecting hard drives and other storage devices, particularly in older computer systems.

Inductors on a Motherboard

Inductors on a motherboard are used to regulate and filter electrical current, preventing unwanted electrical signals from disrupting the system.

CMOS Memory

Non-volatile in the context of CMOS memory means that the data stored in it is retained even when the computer is powered off.

Accessing AWS Services

AWS SDKs (Software Development Kits): Allow developers to access AWS services directly from their code.

AWS Services Fact

AWS Lambda: A serverless computing service that enables code execution without provisioning or managing servers.

Ways to Interact with AWS Services

Using AWS CLI: The AWS Command Line Interface allows using text-based commands to interact with AWS.
Using AWS Management Console: A web-based interface for managing AWS resources.
Programmatically: Developers can use AWS SDKs or APIs to interact with AWS services.

AWS Cloud Adoption Framework (AWS CAF)

AWS CAF aims to provide: A structured approach and guidance to adopting and migrating applications and workflows to the AWS cloud.
AWS CAF perspectives consist of:
- Business perspective: Align cloud adoption with business objectives.
- People perspective: Address organizational change and adoption.
- Process perspective: Define and refine processes for cloud adoption.
- Technology perspective: Consider technical aspects of cloud adoption.

AWS CLI Interaction

The AWS CLI interacts with AWS services through sending requests to AWS APIs.

AWS Management Console

The AWS Management Console is a graphical user interface for managing AWS resources.

AWS CAF Focus

AWS CAF focuses on: Security and Compliance, Cost Optimization, Reliability, and Performance Efficiency while adopting and operating in the AWS cloud.
The AWS CAF can also assist: with migrating applications and workflows to the AWS cloud.

Directory Structure Commands

'cd' command: Changes the current directory within the file system.
'mkdir' command: Creates a new directory.
'rd' command: Removes an empty directory.
'rmdir /s /q directory_name' command: Deletes a directory along with all its subdirectories.
'move source_file destination_path' command: Moves a file from one location to another.
*'del .txt' command: Deletes all files matching the *.txt pattern using wildcards.

Cloud Computing Basics

Cloud computing is: A model for delivering computing services--including servers, storage, databases, networking, software, analytics, and intelligence--over the Internet ("the cloud").
A common pricing model used in cloud computing is: Pay-as-you-go. Customers pay only for the resources they consume.

Storage Devices

Hard Disk Drive (HDD): Stores digital data on rotating magnetic platters.
Solid-State Drive (SSD): Stores data electronically on flash memory chips, offering faster speeds than HDDs.
- SSDs are not characterized by: Being cheaper per gigabyte than HDDs.
USB flash drives are primarily used for: Storing and transferring small to medium-sized files, portable data backups, and installing software.
Tape cartridges are primarily used for: Long-term data archiving and backups.

Windows Command Prompt

Internal commands: Are built-in commands that are part of the Windows Command Prompt executable.
External commands: Are separate programs that Windows Command Prompt executes.

USB Flash Drives

USB flash drives are considered: A type of solid-state storage.

SSD Storage

SSDs use Flash memory technology.

Tape Cartridge Limitations

A primary limitation of tape cartridges for data retrieval is: Slow access times to recover data.
