This is very informative and you made me understand the refresh rate from another perspective.

Amateur copy n paste work. You forgot cache.

You forgot to describe about the different android versions and their meanings.

I was actually a teacher.

But now, I'm more into tech.

You didn't broke it down well like the OP did.
All these your big grammar is too hard for us to digest.

Neoteny:
Correction. ROM is not the same as internal storage. Read-only memory (ROM) is usually where the firmware resides, including things like the baseband. Even that is a misnomer, because modern devices have EEPROM or electrically erasable programmable ROM, which is why firmware can be updated by simple OTA updates. In the old days the EEPROMs were flashed via JTAGS or specialized tools, now we just use a loader program to overwrite old firmware.

Internal storage has read/write access which is why you can store, retrieve, delete and write new information. Read-only Memory doesn't support write access, meaning you can't write/overwrite/store anything

Add camera quality to the list. Some people choose phones cos of camera quality

Educative..

People like us wey dey use Kpalasa nko??

Ok, lemme try again.

There are 2 kinds of memory: volatile and non volatile.

Volatile memory is Random Access Memory, RAM, which temporarily holds instructions and the programs the CPU (and with unified memory, the GPU) uses to run your applications. This memory loses the data once powered down. It's the 8Gb/16Gb etc in your specs.

Non-volatile memory is the type of memory that is not random access, and is stored permanently until deleted or overwritten. This is typically storage, for example your 128Gb, 256Gb, 512Gb etc internal memory. It also comes as external storage eg USB drives and memory cards. These use flash technology to keep the memory persistent even when powered down (flash technology means no battery is needed to preserve state).

Now, RAM and internal storage use read/write (R/W) access to enable copying (reading) and storing (writing) memory. Whether this remains permanent is due to volatility.

Read-only Memory, ROM, is also a non-volatile memory that preserves its state using flash technology. However, unlike RAM and internal storage, ROM supports ONLY Read (copy) access; this means the CPU and Input/Output (I/O) processes can only read/copy from the contents of ROM, but cannot copy to/write to it. This type of memory usually stores the device firmware/OS needed to operate the device, including device drivers and modem baseband for comms.

ROM is of different types: while userland programs can only read ROM and can't write to it or overwrite it, specialized tools and software can rewrite the contents of certain ROMs such as erasable ROMs and programmable ROMs.

Reprogramming or rewriting erasable ROMs is how the underlying OS or firmware is updated ( eg when you upgrade from Android 15 to Android 16, or from q lower baseband to a higher one)

So in summary, internal and external storage are non-volatile memory that can be read and written to, which is how you can store and retrieve data. ROM is a memory storage that's also non-volatile but its contents can only be read and not written to, hence READ-ONLY

Hope that's clear enough

Adewale1603:
it's accurate for a PC system. But that terminology has been embedded in phones terms and usage since

It's only the Chinese OEMs and ODMs that use it, but all other OEMs call it internal storage.

Still applicable for PCs, phones, embedded devices

Wonderful post, learnt alot!

Phone Specs Explained in Plain English (Android Edition) 📱🇳🇬

How far, Nairalanders! Good morning.

You want to buy a new Android phone, you open specs websites, and boom—you are hit with Snapdragon 8 Gen 3, 120Hz AMOLED, 5000mAh, 12GB RAM. It looks like alagbagidigba, right?

Let’s break down exactly what these phone specifications mean, what they actually do for you, and a simple way to visualize them so you never get cheated by phone sellers again.

1. The Processor (Chipset / CPU)
This is the engine and the brain of the phone. Popular names include Snapdragon, MediaTek Dimensity, or Exynos.

What it does: It handles every single calculation. Opening apps, loading games, processing photos, and making sure the phone doesn't freeze. A bad processor means a slow phone, no matter how beautiful the body is.

The Blueprint: Think of the processor like the engine inside a commercial bus. A weak processor is like an old, smoking Danfo engine trying to climb a steep hill on Third Mainland Bridge while carrying full load—it will struggle, heat up, and move slowly. A powerful processor is like a brand-new luxury interstate bus engine that flies past traffic effortlessly...like the Blue link or the one Otti built.


2. RAM (Random Access Memory)
You see things like 4GB, 8GB, or 12GB RAM.
What it does: This is the phone's short-term memory. It holds the apps you are currently using so you can jump from WhatsApp to TikTok and back to WhatsApp without the apps restarting or reloading from scratch. More RAM equals smoother multitasking.

The Blueprint: Imagine a market trader's display table. If the table is tiny (4GB RAM), the trader can only display a few tins of milk. To show milo, they must pack the milk back into a box first. If the table is very wide (12GB RAM), they can spread out noodles, rice, milk, and beverages all at once, attending to multiple customers without any delay.


3. Storage (ROM / Internal Memory)
Usually listed as 64GB, 128GB, 256GB, or 512GB.

What it does: This is the phone's permanent wardrobe. It's where your downloaded apps, WhatsApp videos, system files, photos, and music live permanently.

The Blueprint: Think of storage like the size of a shop container. A 64GB storage is like a small roadside kiosk; it gets choked up easily after you put a few heavy items inside. A 256GB or 512GB storage is like a massive wholesale warehouse where you can stock up on thousands of heavy video files and applications for years without running out of space.


4. Refresh Rate (60Hz, 90Hz, 120Hz)
This is measured in Hertz (Hz) and applies directly to the screen display.
What it does: It is how many times the screen redraws its image every single second. A standard phone does it 60 times (60Hz). Modern mid-range and flagship Androids do it 120 times (120Hz). Higher numbers mean scrolling through Facebook or gaming feels buttery smooth with zero lag stutters.

The Blueprint: Think of it like a deck of cards with drawings on them that create a moving picture when flipped. If you flip the cards slowly with a stiff hand, the movement looks disjointed and rugged. If you flip them with a professional, swift hand, the animation looks perfectly continuous, fluid, and natural to the eyes.


5. Battery Capacity (mAh)
You usually see numbers like 4500mAh, 5000mAh, or 6000mAh.
What it does: "mAh" means Milliampere-hour. It’s simply the size of your fuel tank. The higher the number, the longer the phone stays on before NEPA or your generator needs to save you.

The Blueprint: This is exactly like the fuel tank of a generator. A small 4000mAh battery is like the tank of a small "I better pass my neighbor" generator—it finishes quickly and demands a refill. A 6000mAh battery is like a large diesel tank on a soundproof generator that runs comfortably through a long weekend without blinking.


6. Screen Type (LCD vs. AMOLED / OLED)
What it does: This is the technology behind your display panel. LCD screens are basic and use a massive backlight that stays on constantly. AMOLED or OLED screens make colors "pop," and when something is black on the screen, that specific part of the screen completely turns off. It saves battery and looks crystal clear even under direct afternoon sunlight.

The Blueprint: An LCD screen is like an old billboard illuminated by giant, external floodlights from behind—even the dark areas look slightly gray because of the background light. An AMOLED screen is like a modern digital LED billboard where every single pixel is its own tiny light bulb. When a section needs to show black, those bulbs turn off completely, creating perfect darkness and vibrant colors.


For dem chairman dem:
Next time you go to Computer Village, Slot, or order online:
👉 Want a gaming phone? Look for a high Snapdragon/Dimensity processor and 120Hz.

👉 Want a phone for heavy multitasking? Look for at least 8GB RAM.

👉 Tired of constant charging? Don't buy anything less than 5000mAh.

We will discuss what cookies and caches stand for next and what they actually do for you. I mean in a layman's terms.

Have other inputs? Drop them.

Nice one. I must thank you very much for this explanations.

bonetalk:
Why

As article says.... that's the brain of your phone...

Just imagine for example...a toddler with an advanced thinking how amazing they can be..

So even an older model with advanced processors can still compete with modern day phones...

That's why I hate tecno and infinix and itel...

You wouldn't know because you joined in 2023.

Before AI, those who knew me know I do this.
To banter with you, it's not worth it.

It's just like the swap memory system of PCs. When the usually faster RAM is depleted, the operating system uses a portion of the storage (hard drive in those days 😂 ) to "swap" data and instructions in and out as volatile memory, so that portion works as temporary RAM.

It works exactly the same with modern phones, but its performance depends on the file system technology which handles the read/write processes. Modern phones with fast R/W like UFS 4.x and the new 5.0 (UFS means Universal Flash Storage) are quite fast, but not as fast as the RAM, meaning when your phone uses this reserved portion of storage for memory swapping, you might notice some bit of slowdown especially when gaming.

Hope this helps.
