RAM is also known as random-access memory. It is a form of computer data storage. RAM is the place in a computer where the application programs, data in current use and the operating system are kept so that they can be quickly reached by the computer's processor. There are two different types of RAM which are DRAM, Dynamic Random Access Memory, and SRAM, Static Random Access Memory. DRAM is a the more common type but when it comes to a faster memory, SRAM is faster.
Cache is a short-term storage. It is used to accelerate some computer operations by storing data for a time being that is most likely to be used again. It is a RAM that a computer integrated circuit can be connected faster than a regular RAM.
ROM :-
ROM is an abbreviation of Read-only memory. ROM is a computer memory that can store your data for good. It is kind of the opposite of RAM. Even when you shut down the computer, the data that have been stored in ROM doesn't get lost unlike RAM. Within ROM, there is a program that allows your computer to be reboot or refresh every time it is turned on. ROM cannot be adjusted. It is a "built in" computer concept that holds data that normally only can be read and not written to.
Flash Memory :-Flash memory is a type of memory chip that maintains data even though power supply is unavailable. It is a nonvolatile storage that can be wiped of and reprogrammed. It is often used in memory cards, USB flash drives and many more, for common transferring and storing data between computers and digital devices.
Graphic Card :-A graphic card is also known as a video card. It is a gadget that is set up in the computer. It has a graphics processing unit that is designed to assist in the display and process of graphics. Graphic cards are printed circuit boards that perform double roles of sending pixels to the display and they give a particular type of processing by using a graphical processing unit.
Sound Card :-
A sound card is an element inside a computer that supports audio output and input potentiality. It is essential for almost all CD-ROMs and is very common in computers nowadays. It is a device that can be put into the computer for the usage for multimedia productions.
Network Interface Card :-
A Network Interface Card can be shortened to NIC. It is a card that is built into the computer so that it can be connected to a certain network. It lets information proceed between the user's computer to other networks. Most NICs are created for a specific type of network, protocol, and media, however only some can suffice diverse networks.
Plug & Play :-
Plug & Play is easier known as PnP. Plug & Play is a guideline for connection of components to personal computers, where a gadget only needs to be connected to a computer to be able to be set up to work flawlessly even without the users doing anything to it.
Universal Serial Bus Port (USB) :-
A Universal Serial Bus Port or easily known as a USB port, is a customary cable connection interface on personal computers and consumer electronics. It is the most used hardware interface for attaching components or elements to a computer. It lets data to be transmitted between a device to another. USB ports also supplies electric power access to devices through a cable without their own power source. USB ports connects peripheral devices like digital cameras, mice, external hard disks, thumb drives and many more.
Serial Port :-
Parallel Port :-A parallel port is a connector for gadgets that sends or receives various bits of data at the same time by using a few wires. It is a cable on a computer used to connect devices like printers through a parallel interface.
Firewire Port :-
A Firewire port is a type of a serial port that makes use of the FireWire technology for transferring data very quickly from one device to another. It is normally used to transfer large files like videos.
Ethernet Port :-
An Ethernet port is a socket on a computer or network device for plugging in an Ethernet cable. It is a connection point for, according to wikipedia.com, a family of frame-based computer networking technologies for local area networks.
High Definition Multimedia Interface (HDMI) Port :-The HDMI port is a standard for video networking which can support all HDTV standards. It is an input and output connection for transferring of digital HD videos and multichannel audio over a single cable.
