It stored data as electrically charged spots on the face of a cathode ray tube.ĥ. Williams tube was the first practical type of Random access memory, it was developed in 1947. T he first commercial DRAM IC chip, the Intel 1103, was introduced in October 1970.Ĥ. RAM of a computer can be improved by closing unnecessary applications or by running the PC on sleep mode.ģ. But for higher RAM, better processor and hardware is also required.Ģ. It can be done by upgrading from a 4gb system to 6 or 8gb system. For higher functions like video editing and gaming more RAM is needed. Generally better RAM also need better processor and better quality of hard disk.įollowing is some important and interesting information about RAM :-ġ. But to support a more powerful RAM better quality of hardware is also important. Higher value of MHz leads to higher speed of RAM. There are different levels of speed RAM can have ranging from 2000 MHz to 5000 MHz. DDR stands for double data rate and allows a user to transfer more than one file at any given time. It is available in multiple variations like DDR2, DDR3, DDR4 and DDR5. Presently, there are 3 major types of RAM available in the market, static RAM ( RAM), dynamic RAM ( D-RAM ), and synchronous dynamic RAM ( SD-RAM ).Ĭurrently most common type of RAM is DDR-RAM. But, their size, design and performance has evolved a lot over the period of last few decades. Since the early days of computers, RAM has been there. If RAM of our laptop is limited and weak, then pages will take more time to load, despite the network being good. Suppose, we are browsing internet and we have opened 6-7 web pages in different tabs at the same time, then it is RAM which is functioning. It is ten to hundred times faster than the hard disk, where information is stored for the long term. RAM is super fast, as information stored in it is required very quickly, within seconds. Every device which perform some form of computation has RAM like laptop, smartphone, smart TV and some other devices. RAM of a computer is the space in which this data is stored. This data is stored only on a temporary basis, and once we switch off our computer it gets deleted. there is a fraction of data which computer has to access immediately. When we do things like web browsing, video streaming, gaming etc. RAM stands for random access memory, it is the short term memory of a computer. It decides how smoothly and how fast we will be able to perform activities like web browsing, video streaming, gaming etc. Random access memory is one of the most important features of a computer or laptop.
