You can start with 4GB as your budget configuration then add more memory later as needed. Chromebooks with 4GB RAM should handle a decent number of browser tabs easily, so when faced with the choice of more memory or a faster storage drive i. For people doing office work or gaming, 16GB of memory can be a hedge against future needs. However, for content creators and people who keep dozens and dozens of tabs open in multiple browsers 16GB is a starting place.
Renders can gobble up memory, for example. If you anticipate that you could need more RAM down the road, look for laptop models that support user-serviced upgrades. People considering more than 16GB of RAM should be actively using programs known for gobbling up system memory or requiring it for optimal performance—for example, video editors working on time-sensitive projects.
Most people think that laptops are not upgradable but that is not true anymore. Now that laptop memory prices are low it is a great time to give your old laptop a bit of a kick. The two memory modules are marked with arrows.
This laptop has megabytes of memory. One chip is 64 megs and the other is External me mory, also called "secondary memory" refers to a storage device that can retain or store data persistently.
They could be embedded or removable storage devices. Examples include hard disk or solid state drives, USB flash drives, and compact discs. ROM stands for read-only memory. It is non-volatile, which means it can retain data even without power.
It is used mainly to start or boot up a computer. Once the operating system is loaded, the computer uses RAM , which stands for random-access memory, which temporarily stores data while the central processing unit CPU is executing other tasks. With more RAM on the computer, the less the CPU has to read data from the external or secondary memory storage device , allowing the computer to run faster. RAM is fast but it is volatile, which means it will not retain data if there is no power.
It is therefore important to save data to the storage device before the system is turned off. This allows the CPU to perform more instructions at a given time. It was popular in the early s and was mainly used for video game devices and graphics cards, with transfer speeds up to 1 GHz. Although operating on the same principles, the modules are not backward-compatible.
Each generation delivers higher transfer rates and faster performance. Figure 1. Some brands and models of laptops, such as ultraportable styles, have a fixed memory size that cannot be upgraded. A laptop requires a specific type of memory, such as one of those in the list above. The same is true for the speed and bandwidth requirements of the system; determine the proper memory type your system accepts before purchasing a memory upgrade.
Also, a computer has a maximum amount of RAM it can accept that is not based on the physical number of slots. For example, you may be able to purchase two 16 GB memory modules, but that 32 GB total may be over the maximum allowed by your system.
All these limitations are listed in the specifications of any laptop, so be sure to take note of them. First, find out what the maximum possible memory of the system is. This is listed by most manufacturers and indicates the upgrade potential of the system. Next, look at the memory configuration. A system configured with a single memory module has a second memory slot open, one that can be used to expand the amount of RAM in the future by adding a second memory module.
Upgrading memory in a system with both memory slots filled with memory modules comes with a few additional considerations. In a laptop with two 4 GB modules totaling 8 GB of system memory , one module will need to be replaced with a larger capacity module. However, it is better to upgrade both 4 GB memory modules at the same time to ensure the fastest performance.
Memory modules are usually paired to work with each other in a dual-channel mode and having two modules of differing capacities will not work as efficiently as would a matched pair.
It is best to use memory modules with matching capacities, speeds, and manufacturers. A better choice is to buy a matched pair of modules in a set when upgrading memory.
Many laptops have a small panel on the underside of the system that provides access to its memory module slots. On other systems, the bottom cover may need to be removed to access the memory modules. In these cases, it is possible to purchase a memory upgrade and install it yourself without much trouble. If a system doesn't have an access panel or other means to get inside the computer, the memory, most likely, cannot be upgraded. In these cases, the laptop may be opened by an authorized technician with specialized tools to upgrade the memory.
Of course, this comes with additional costs.
