Final answer:
When a PC is installed at a user's site, hardware upgrades like additional memory are often installed after installation.
Step-by-step explanation:
When a PC is installed at a user's site, hardware upgrades like additional memory are often installed after installation. This is because the initial installation process involves setting up the basic components of the PC, such as the operating system and necessary software.
After the installation is complete, if the user decides that they need more memory, they can then install the additional memory. This can be done by opening the PC case, inserting the memory module into the appropriate slot, and securing it in place.
It is important to note that the installation of hardware upgrades does not usually occur before or during the initial installation of the PC. Hardware upgrades are typically done at a later time, after the user has determined the need for additional resources.
Hardware upgrades, such as additional memory, are often installed during installation of a PC at a user's site. This is generally the most convenient and efficient time for these upgrades to take place, as it allows the technician to ensure that all components are working correctly together from the start. Performing upgrades during installation helps in avoiding potential compatibility issues and system instability that can arise if upgrades are installed after the PC has already been in use.
