When shopping for a laptop computer, one of the most important factors to consider is the amount of RAM (random-access memory) the device has. RAM is important because it allows a computer to store temporary data, such as open files and Web pages, so that you can access them quickly.
Laptops typically come with two or more RAM slots, and many models now also come with a built-in solid-state drive (SSD) that can store large files more quickly than a traditional hard drive.
RAM is measured in gigabytes (GB), so a laptop with 4GB of RAM would be equivalent to four 1GB sticks of RAM. Laptops typically come with at least 1GB of RAM, but some high-end models offer 4GB or even 8GB.
If you plan on using your laptop for intensive tasks such as photo editing or video encoding, you may want to consider purchasing an upgrade to ensure you have enough memory available.
