Shadowing Practice: 10+ Key Memory & Storage Systems: Crash Course System Design #5 - Learn English Speaking with Video
Les maken...
1
Today, we're diving into the world of computer memory and storage.
2
Let's get started.
3
First up, we have the fundamental dual, RAM and ROM.
4
RAM or Random Access Memory is a type of memory that stores data temporarily while the computer is running.
5
is fast and flexible, juggling all the programs we are running at any given moment.
6
However, RAM is volatile, meaning it loses its stored data when the power is turned off.
7
ROM, or read-only memory, is a type of memory that retains data even when the power is off.
8
It is non-volatile and used to store essential information, like firmware and the BIOS, that your computer needs to boot up.
9
Now let's explore the different types of RAM, including SRAM, DRAM, and everything in between.
10
SRAM or Static Random Access Memory is a fast
11
and expensive type of RAM used in high speed applications like CPU caches where quick access time is crucial.
12
DRAM or dynamic random access memory is lower and cheaper than SRAM.
13
It needs to be constantly refreshed to retain data, making it more high maintenance.
14
There are many types of DRAM including FPM DRAM, EDO DRAM, SDRAM, and DDL DRAM,
15
with each generation bringing faster speeds and increased efficiency.
16
Many are obsolete, and the common types of DRAM in the market today are DDL variants like DDR4 and DDR5.
17
GDDR is also worth mentioning.
18
It is a specialized type of DRAM optimized for faster data transfer rate,
19
which the GPU needs for its massive parallel processing.
20
GDDR6 is the most widely used today.
21
Now let's dive into some essential roles of ROM, firmware and BIOS.
22
Firmware is a type of software stored in ROM that controls how hardware devices communicate with each other.
23
BIOS, or Basic Input Output System, is the first software your computer runs when you power it up.
24
It's responsible for starting your computer, initializing hardware components and handing over control to the operating system.
25
Now let's explore hard disk drives and solid state drives.
26
Hard disk drives or HDDs have been around for a long time.
27
They store data on spinning magnetic disks and are known for their lower storage capacity at a low price.
28
Solid state drives or SSDs use NAND based flash memory,
29
providing fast data access, reduce power consumption and increased durability compared to hard disk drives, but come at a higher price.
30
NVMe or Non-Volatile Memory Express is a high performance interface for SSDs that connects directly to the CPU via PCIe lanes.
31
This allows for lower latency and significantly faster data transfer rates compared to SATA based SSDs.
32
Need to take your data on the go?
33
Let's talk about flash drives and SD cards.
34
Flash drives, also known as USB drives or thumb drives, are small plug and play devices you can use with any USB port.
35
They're easy to use and perfect for transferring files between computers.
36
SD cards are commonly found in cameras and smartphones.
37
They're smaller than a postage stamp but can store thousands of files.
38
SD card comes in three main physical sizes, SD, micro SD and mini SD.
39
And there you have it, our quick journey through the world of computer memory and storage.

Zo oefen je met deze video
- Luister de hele video één keer zonder te spreken en noteer de woorden die je niet kent.
- Spreek zin voor zin na op normale snelheid en herhaal elke zin tot je ritme gelijk is aan dat van de spreker.
- Neem jezelf op en vergelijk met het origineel; let daarbij op woorden als disk, volatile, durability.
Wat is de Shadowing-techniek?
Shadowing is een wetenschappelijk onderbouwde taalleermethode die oorspronkelijk is ontwikkeld voor professionele tolkentraining en gepopulariseerd door polyglot Dr. Alexander Arguelles. De methode is eenvoudig maar krachtig: je luistert naar native Engelse audio en herhaalt het onmiddellijk hardop — als een schaduw die de spreker volgt met slechts 1–2 seconden vertraging. In tegenstelling tot passief luisteren of grammaticadrills, dwingt shadowing je hersenen en mondspieren om echte spraakpatronen tegelijkertijd te verwerken en te reproduceren. Onderzoek toont aan dat het de uitspraaknauwkeurigheid, intonatie, ritme, verbonden spraak, luisterbegrip en spreekvaardigheid aanzienlijk verbetert — waardoor het een van de meest effectieve methoden is voor IELTS Speaking-voorbereiding en echte Engelse communicatie.
