Random Access Memory, or RAM, is used by computers to store and access information using a random order. This resource provides a temporary way for computers to process electronic data, while making computers more responsive and helping operate memory-intensive programs. RAM chips are only capable of storing and accessing information when electrical power is present.Know More
When a computer is shut down or loses electrical power, information stored in RAM is lost. RAM storage is temporary, and when equated to the human brain, RAM is equivalent to short-term memory. This tool improves a computer’s ability to operate memory-extensive programs. When a computer runs a program or accesses a file, it temporarily loads information from the hard drive and transfers it to the RAM. This allows the computer to access information smoothly without extended delays. RAM is considerably faster than hard drives; the speed of high-quality hard drives can reach more than 1,000 MB/s, whereas RAM exceeds speeds of 15,000 MB/s. As a result, RAM is significantly more expensive than hard drives.
The first RAM chips were proprietary designs of computer companies and only worked in computers built by that company. With the invention of single in-line memory module, or SIMM, chips, users were able to transfer RAM chips from one computer brand to another.Learn more about Computers & Hardware
Random access memory is used to store temporary but necessary information on a computer for quick access by open programs or applications. The data stored in RAM can be accessed randomly, meaning a computer does not need to search through large blocks of data to find what it needs. This targeted access makes it possible to run complex programs quickly and efficiently.Full Answer >
RAM is used for a variety of tasks and is highly versatile, as opposed to ROM and CMOS, which contain crucial — and permanent, in the case of ROM — data related to systems operation, while virtual memory and cache are used to simulate or manipulate RAM during tasks. Virtual memory and cache are designed to enable memory resources for increasingly fast processors.Full Answer >
In communication, computers are used on all levels of telephone networks, and some systems can even replace phones entirely. Voice-over-IP networks have become very popular. Traditional telephone technology lacks the bandwidth of Internet connections, and many companies advocate for full replacement.Full Answer >
Mainframe computers are used to store large amounts of data that wouldn't fit into a normal-sized computer system. Mainframe computers are most often used by large corporations and government agencies that require a large amount of information to be stored in a centralized secure location. They are named after the large cabinets that were needed to house them when they were physically large.Full Answer >
