How to understand laptop specs?


So how to understand laptop specs?

When you are looking to buy a laptop, the specifications are an important consideration. But what do they mean? This article will help you to understand the most important specs and what they mean for you.

What are laptop specs and why do they matter?


Random Access Memory, or RAM, is used to store information temporarily. The more RAM a laptop has, the faster it can access data. So if you’re going to be doing a lot of multitasking or if you plan on installing a lot of software, you’ll want to make sure your laptop has plenty of RAM.


The Central Processing Unit, or CPU, is the brain of the laptop. It’s responsible for performing calculations and handling instructions. If you’re going to be doing a lot of number-crunching or graphics-heavy tasks, then you’ll want to make sure your laptop has a powerful CPU.


Storage is the place where your data is saved. If you plan on storing a lot of music, photos, and videos on your laptop, then you’ll need a lot of storage space. You can choose between HDD (hard disk drive) and SSD (solid state drive) storage. HDDs are cheaper but they’re also slower and use more power. SSDs tend to be smaller and faster, but they’re also more expensive.

Graphics card (GPU)

The graphics processor is essential for your laptop if you’ll be doing a lot of graphics-heavy tasks. For example, if you plan on editing photos or videos on your laptop often, then you should invest in a powerful GPU. But if all you do is check and send email and browse the internet, then an integrated GPU will work just fine.


This refers to the types of ports that are available on your laptops such as USB, HDMI port or Thunderbolt 3 port. Many modern laptops now include some kind of USB Type C connector as well as as standard nowadays as part of their connectivity options. If you’re looking to connect external displays and peripherals to your laptop, thenbe sure to look for a port like the HDMI port or the Mini DisplayPort. If you plan on transporting your laptop often or if it’s something that will see a lot of travel, then we recommend getting a model with an Ethernet jack as well as at least one USB-A 3.1 (or Thunderbolt 3) port.

Understanding CPU speed, cores, and threading in laptop specs


When shopping for a laptop, one specification that you’ll see listed is the clock speed of the CPU. The clock speed refers to how fast the processor executes instructions and processes data. A higher clock speed means your laptop will perform tasks more quickly than a slower clock speed.

The first number you see when looking at the specs for a desktop or laptop is usually the gigahertz (GHz) measurement, which refers to how many billion cycles per second it can complete. For example: 2 GHz = two billion cycles per second. If you want to compare laptops and what sets them apart from each other, this is an important spec to check out first because it’s easy-to-understand and quick to look up.

However, MHz is also a measurement that is used and it stands for megahertz which is 1,000,000 Hz. So a 2 GHz processor is equivalent to 2,000 MHz.

GHz or MHz alone don’t tell the whole story though. You also need to know how many cores (and threads) a processor has.


A core is simply one part of the CPU that can process instructions at once. A dual-core processor has two cores, while a quad-core processor has four cores. Some newer processors have more than four cores. More cores means the processor can handle more tasks simultaneously.

CPUs today generally come in two types: dual-core and quad-core (although there are other types such as hexa-cores). A dual-core CPU means that there are two cores which can process instructions at once. On a quad-core CPU, four cores can process instructions simultaneously. This is where things get confusing though because not all processors with twice or four times the number of cores are actually twice or four times as fast.

CPUs with multiple cores share the same clock speed. So if a dual-core CPU has a 3GHz clock speed, then that means that one core is running at 3GHz and the other is running at 3GHz—they have separate sets of memories, however. Because of this shared use of resources, it would take each core twice as long to process instructions than it would on a single-core CPU with the same clock speed.


Threading allows an operating system to split up a task into multiple parts and assign each part to a different core. For example, if you’re watching a video while deleting some files and downloading a file, the processor would normally have to wait for the video to finish before it could start working on anything else. Threading can allow the operating system to save time by assigning different tasks—such as playing the video and deleting or downloading files—to different cores simultaneously.

CPUs with more total processing power are often described not by how many cores they have overall but by how many threads they can handle at once. A thread is an element of code being executed simultaneously along with others in some kind of software. In a dual-core CPU with hyperthreading, the operating system sees four threads of execution even though it has only two cores. This is done through hardware-level thread duplication or time-slicing. It’s generally not as efficient as having a separate core for each thread because this would require duplicating all the registers and caches used by each logical processor.

Understanding RAM in laptop specs

RAM stands for Random Access Memory. This is temporary storage memory on your laptop which the operating system (Windows, Mac or Linux) uses to store everything that’s currently running on your laptop including programs, open browser tabs and any documents you’re using. The more RAM you have installed on your laptop, the more things you can load into it at once without seeing your laptop grind to a halt while it does some heavy processing. If you only work with one document at a time then 8GB of RAM will be sufficient but if you like to keep lots of apps open simultaneously while working on several documents then 16GB would be better.

While most people think of RAM as just background storage, its properties allow it to actually play an important role in the speed of a laptop. RAM stands for Random Access Memory and is a type of storage that allows data to be accessed randomly. This means that any byte of information can be accessed without having to go through all of the preceding bytes, making retrieval much faster.

RAM is different from other forms of storage because it doesn’t have a mechanical arm like a traditional hard drive does. When you save something to your hard drive, the arm needs to physically move to the correct location on the disk in order to store or retrieve the desired data. Because RAM is made up of microchips, there’s no physical arm so it can access data much faster.

The downside to RAM is that it requires power in order to keep the information stored. This is why when you turn off your laptop, all of the information in RAM is lost. It can also be accessed by anyone who has access to it when it is powered on—even random people on the street. For this reason, many companies implement security measures so that their data cannot be compromised in this way.

Technical aspects

The amount of time that a bit of data will remain in RAM before being replaced depends on how often that information is used and what functions are performed while using it. If there’s no use for the data in question, then it will be replaced with another piece of information much more quickly than if lots of calculations were made using that piece or if someone wanted to keep track of what they had already done (a rudimentary to-do list, for example).

The amount of time that a bit of data is stored in RAM usually correlates with the importance that the information has. If it is unimportant and not often used, then it will be moved out of RAM within milliseconds if not seconds; whereas important pieces of data will remain in memory until they are no longer useful or until someone actively goes in and deletes them.

An average laptop today has between 4GB and 16 GB (the maximum allowed by law) of total RAM available to use—this number varies depending on whether you have 32 bit or 64 bit architecture. The operating system takes up some of this space, but around 1 GB is reserved for other uses so that the system can work well. This means that, realistically, you have 3-14 GB of RAM to use for your applications and data.

RAM is a volatile memory, which means that when it loses power it loses all the data stored inside it. For this reason, RAM is constantly being refreshed with new information; if it weren’t, everything currently in RAM would be lost as soon as the power was turned off.

RAM is measured in bytes (B), kilobytes (KB), megabytes (MB), gigabytes (GB), and terabytes (TB). A byte is made up of 8 bits, so 1 KB is 1024 bytes, 1 MB is 1024 KB, and 1 GB is 1024 MB.


How to understand hard drive size and speed in laptop specs

One of the most important factors to consider when purchasing a new laptop is its hard drive capacity and speed. Hard drive size is measured in gigabytes (GB) and terabytes (TB), while hard drive speed is measured in revolutions per minute (RPM). It’s important to understand how these two factors affect your laptop’s performance, so you can make an informed decision about which one to buy.

The hard drive is the part of the laptop where your data is stored. When you save a document, for example, it’s saved to the hard drive. The faster the hard drive spins, the faster it can access and send data. This is why a fast hard drive is important laptop that are used for tasks such as playing PC games or editing video. Generally, a typical desktop laptop will have a 7200 RPM hard drive, while laptops and all-in-ones typically have 5400 RPM drives.

Hard drive speed is measured in revolutions per minute (RPM), and it’s not to be confused with storage capacity. This article explains how to understand hard drive size and speed, including the differences between these two important factors for any laptop user!

The document is saved on your laptop’s hard drive (the big box that stores data). If you want to store more information (or if you want your files to open more quickly) you’ll need a bigger hard drive. A larger capacity means that the platters inside the hard disk can hold more data.

Space vs speed

But just because a hard drive has a lot of space doesn’t mean it can save data quickly. The speed of the hard drive is measured by how many revolutions its platters make in a minute and is usually referred to as rotations per minute or RPMs. So, a 5400 RPM drive is slower than a 7200 RPM drive.

When you’re shopping for a new laptop, you’ll see the size of the hard drive listed in gigabytes (GB), terabytes (TB), or even petabytes (PB). One gigabyte is equal to 1,024 megabytes, one terabyte is equal to 1,024 gigabytes, and one petabyte is equal to 1,024 terabytes. The size of the hard drive is important, but you also need to consider the speed of the drive.

The faster a hard drive rotates, the more quickly it can save data. So, if you’re looking for a new laptop and you have a lot of data to store, you’ll want to look for a model with a large hard drive that also has a high RPM rating. If you just need to store a few files or don’t plan on adding many more files in the future, then you can choose a model with a smaller hard drive and lower RPM rating.

When shopping for an external hard drive, you’ll also see the size of the drive listed in gigabytes (GB), terabytes (TB), or even petabytes (PB). But what do these numbers mean?

One gigabyte is equal to 1,000 megabytes (MB) or 1,024 kilobytes (KB). So, if you’re looking for an external hard drive that has a capacity of 500GB, that means it can store 500GB worth of data.

One terabyte is equal to 1,000GB or 1,024MB. So, if you’re looking for an external hard drive that has a capacity of 2TB, that means it can store 2TB worth of data.

Knowing what a GPU is

It is important for everyone who wants to play games because it will make you crucial for the industry. Knowing what a GPU is is also necessary if you plan on doing 3D modeling or any other tasks that require various calculations.

It might seem like knowing what a GPU is would be simple but it’s actually very complex and can get quite complicated. Learning about how CPUs process information has helped me learn about GPUs, however, the subject of exactly how they work isn’t well-documented so much of the research I’ve done was through reading articles online and scholarly articles written by people with PhDs in laptop science – this article being one of them! The best way to describe the difference between CPUs and GPUs is that focuses on handling single operations while the latter handles multiple operations.

Let’s look at CPUs first though. A CPU is basically a complex calculator that can handle one task each time it’s activated, and to do this it needs to be told exactly what to do by following a program or set of rules (algorithms). The components and tools used in the CPU and laptop also play a significant role in how well it can process information: there are various levels of memory storage, input, output and processing speeds, the number of cores/threads available for calculations, etcetera – we could go on about this for hours so I’ll spare you!

A GPU however is very different from this as instead of being programmed step-by-step it has thousands or even millions of small, but very powerful cores which can all run in parallel. This works similarly to how you would expect from a neural network with artificial intelligence as the graphics card makes its own decisions based on what it’s been instructed to do by the user and its current environment (right down to things like temperature, fps etcetera). In reality, though, deciding on an algorithm can be rather time-consuming and it needs to be carefully planned out before the GPU is told exactly what it needs to do – unsurprisingly, a CPU has no trouble doing this as programming a video card with complex algorithms is not something most people will bother having a go at!

The difference between integrated graphics cards vs discrete graphics cards

When it comes to graphics cards, there are generally two types: integrated and discrete. Integrated graphics cards are those which are built into the motherboard, while discrete graphics cards are separate units that need to be installed in a PCI-E slot. The main difference between these two types of cards is that integrated cards utilize the system’s CPU to handle all the graphical processing, while discrete cards have their own dedicated processor (the GPU). This difference means that integrated cards are generally much slower than discrete cards – however, they do tend to use less power and generate less heat, making them better suited for laptops or low-power systems.

The most important factor when choosing a graphics card is how it be used. If you’re looking for a cheap solution for playing HD movies and browsing the web, then an integrated card will do just fine. However, if you want to play games on high graphics settings or render complex 3D models, then you should go with a discrete card.
