Session-3: Internal Components of PC
A hard disk drive is a data storage device that stores information in the form of magnetic particles on concentric circles called tracks on one or more rigid disks called platters. It consists of platters, read/write heads, and motors that spin the platters and position the heads. Hard drives store operating systems, software, and files and come in various capacities ranging from 10GB to multiple terabytes. Common interface types are IDE, SATA, and SCSI and hard drives can fail due to issues like no operating system, cable problems, or not being detected.
This document discusses installing and maintaining computer hardware. It covers objectives like identifying the CPU socket on the motherboard and practicing installing a processor. It provides details on connecting cables, brackets and power to the motherboard. There are also exercises to recognize motherboard components and identify CPU sockets by number for Intel and AMD processors. The document instructs how to install a processor into the zero insertion force socket on the motherboard.
The document provides an overview of hard disk drives including their history, working, characteristics, types, organization of data, and manufacturers. Hard disk drives were first introduced in 1956 to store data for IBM computers and now come in two main types - PATA and SATA. They work by magnetizing ferromagnetic material to represent binary digits and reading the data back by detecting magnetization. Proper shutdown is needed before unplugging a computer to allow the hard disk head to safely separate from the disk platter.

M|18 Deep Dive: InnoDB Transactions and Write PathsMariaDB plc
The document discusses the write path for transactions in InnoDB from the client connection to physical storage. It compares InnoDB's transaction and storage layers to the OSI model. Key aspects covered include how SQL statements are executed, how rows are locked, written to indexes and undo logs, and how transactions are committed or rolled back. Mini-transactions provide atomic durable changes to multiple pages using write-ahead logging to the redo log.
The motherboard is the main circuit board in a computer that holds the central processing unit (CPU) and main components. It allows these components to communicate and work together. Motherboards come in different form factors depending on size and shape to fit cases and components. The most common form factors are ATX, MicroATX, and BTX. The motherboard contains important components like the CPU socket, memory slots, expansion slots, chipset, and connectors for ports, power supply, and drives. It acts as the central hub connecting all the computer's components.
This document discusses solid state drives (SSDs) as an alternative to traditional hard disk drives (HDDs). It describes SSDs as using solid state memory rather than mechanical components to store data. The document outlines SSD form factors, architecture involving flash memory, controllers, caches and host interfaces. It compares the technical aspects of SSDs and HDDs, noting SSDs advantages as faster speeds, reliability and lower power use, while their main disadvantage is higher costs. The document concludes SSDs will likely replace HDDs in most applications due to their performance benefits.
Solid state drives use solid state memory like NAND flash instead of spinning disks. They have faster access times than hard disk drives. An SSD contains a controller, flash memory, and an interface. The controller manages read and write operations to the flash which is organized into pages and blocks. SSDs are found in devices like thumb drives, memory cards, and embedded systems. They provide benefits like faster startup, access, and application loading compared to HDDs. SSDs are used where fast storage access is important, like financial trading systems.

Solid State Drive (SSD) is a storage device that uses solid-state flash memory rather than a rotating magnetic medium. SSDs provide faster access time and have no moving parts, compared to traditional hard disk drives (HDDs). SSDs use flash memory, either NAND or NOR types, and store data in semiconductors rather than on magnetic disks. While SSDs are more expensive than HDDs, their performance advantages, such as faster read/write speeds and more durability, make them suitable for applications requiring quick access to large amounts of data.

Overall, SSDs are expected to become the basic storage component in servers and PCs due to their efficiency advantages over traditional hard drives.
Faster, better, stronger: The new InnoDBMariaDB plc
For MariaDB Enterprise Server 10.5, the default transactional storage engine, InnoDB, has been significantly rewritten to improve the performance of writes and backups. Next, we removed a number of parameters to reduce unnecessary complexity, not only in terms of configuration but of the code itself. And finally, we improved crash recovery thanks to better consistency checks and we reduced memory consumption and file I/O thanks to an all new log record format.
In this session, we’ll walk through all of the improvements to InnoDB, and dive deep into the implementation to explain how these improvements help everything from configuration and performance to reliability and recovery.
The document provides an overview of the InnoDB storage engine used in MySQL. It discusses InnoDB's architecture including the buffer pool, log files, and indexing structure using B-trees. The buffer pool acts as an in-memory cache for table data and indexes. Log files are used to support ACID transactions and enable crash recovery. InnoDB uses B-trees to store both data and indexes, with rows of variable length stored within pages.

SSD - Solid State Drive PPT by Shyam jos Shyam Jos
Solid State Drive (SSD)
In 1995, M-Systems introduced the first flash-based solid-state drives. SSDs use non-volatile solid state memory like NAND flash or DRAM to store data without moving parts, distinguishing them from traditional hard disk drives. SSDs have significant performance advantages over HDDs with faster access times and read/write speeds, higher reliability since there are no moving parts, lower power consumption, and silent operation. However, SSDs currently have higher costs and offer less storage capacity than HDDs.
1. A hard disk drive is a data storage device that stores information in 0s and 1s on magnetic platters.
2. It contains platters, read/write heads, and motors that allow it to read and write data to the spinning platters.
3. Hard disk drive capacity is measured in gigabytes or terabytes and depends on the number of platters, tracks, sectors, and bytes per sector.

Los semiconductores más conocidos son el silicio y el germanio. El silicio es el elemento semiconductor más utilizado en la fabricación de componentes electrónicos debido a que su comportamiento es más estable frente a perturbaciones externas. Los semiconductores en sí no presentan propiedades prácticas, por lo que se los contamina para darles propiedades especiales como alterar la probabilidad de ocupación de las bandas de energía.
