Many types of circuits comprise a computer’s internal memory, including RAM, ROM, EPROM, EEPROM and FLASH ROM. Distinct from disks used for data storage and often called hard memory, these types of memory function together to run a computer system. The most familiar is RAM, or Random Access Memory, which provides temporary storage for work that's in-progress. Other types of memory are read-only.Know More
Unlike hard drives, which are classed as storage, internal memory refers to circuits that give the computer specific kinds of rote commands. RAM allows the computer to find files on its hard drive, hold files open to be worked on and runs several programs simultaneously. RAM has no static content. ROM, or read-only memory, contains recursive instructions for the computer, including in what order the components boot up and which drivers are loaded into its memory.
The instructions held in ROM repeat over and over again by rote to keep the computer running smoothly and usually are written for specific components of the computer system. When the system requires updates, users might need special software and sometimes hardware to upgrade the system. With the development of newer and faster ROMs, RAM no longer handles as many recursive tasks and is more efficient.Learn more about Computers & Hardware
A "pagefile.sys" is a hidden file used by Windows and placed in a root of a hard drive that allows the system to free up RAM for applications that are in use. Applications that are minimized or inactive have memory shifted to a pagefile.Full Answer >
RAM is the term used to describe the memory system of computers. The amount of RAM, or random access memory, that computers contain varies widely among operating systems. All computers come with a standard amount of integrated memory, and their storage capacities can be increased with the installation of certain devices, called RAM disks or RAM drives.Full Answer >
To upgrade the RAM of a MacBook Pro, first identify the specific model of the machine and the amount of RAM that is permissible to add, then confirm that the memory you wish install is compatible with your MacBook Pro. Remove the screws holding the bottom case of the MacBook, and then remove the existing memory card from the machine by disengaging the security levers and pulling the card out. Carefully install the new memory card into the existing card slot until it securely snaps into place. Replace the cover to complete the RAM upgrade procedure.Full Answer >
To fix a slow computer, vacuum the hardware, remove old programs, run Disk Cleanup, defragment the hard drives, upgrade the RAM and use an external hard drive. This can be an easy or difficult process, depending on the problem.Full Answer >
