RAM Chips and ROM Chips Random Access Memory (RAM)  is the short-term memory used to store information that is being processed. It is available as a RAM Chip, which is an integrated circuit (IC) Soldered on the motherboard. The two types of RAM are static RAM(SRAM) and dynamic RAM (DRAM). SRAM is expensive to produce, but faster and requires less dynamic power than DRAM. SRAM is typically used as a cache memory for the CPU. The following figures Shows RAMs:   Memory modules come in several form factors, such as: Single inline memory (SIMM)- SIMM has a single row of 30 or 72 edge connectors on the bottom of the module. Single refers to both sides of the module having the same pinout. Dual inline memory module(DIMM)- DIMM is available in 168-pin, 184-pin, and 240-pin versions. Dual refers to each side of the module having a different input. Small Outline DIMM(SODIMM)- SODIMM is a compact version of the standard DIMM module, available in various pinout for use in notebook compute...

Ports A port serves as interface between the computer and other computers or peripheral devices. The ports vary depending on the kind of equipment that will be connected to the port such as to connect a monitor, keyboard, mouse, game controllers, printers, webcam, speakers the ports sizes are different, as shown in the following image: Ports in Motherboards The usage of ports is as follows: Serial Port: This port is used with a 9-pin connector. It is no longer in use, because these are replaced by interfaces such as Ethernet, FireWire and USB. PS/2 Port: This port was earlier used to connect keyboards and mouse. These were round ports for six pin connectors. They have now been replaced with Universal Serial Bus (USB) ports. Parallel Port: A common parallel port is used for 25 pins connector. These ports are similar to serial ports and were used to connect printers and joysticks. They are no longer in use and have also been replaced by USB ports. Video Graphics Array (VGA) Port: ...

  Computer Hardware- (Peripheral & Components) Computer hardware refers to the physical parts of a computer, outside and inside the system unit. The internal parts of a system are known as components, while external parts are typically called peripherals such as the keyboard, mouse, speakers and printers. कंप्यूटर हार्डवेयर का तात्पर्य कंप्यूटर के भौतिक भागों से , सिस्टम यूनिट के बाहर और अंदर से है। एक प्रणाली के आंतरिक भागों को घटकों के रूप में जाना जाता है , जबकि बाहरी भागों को आमतौर पर कीबोर्ड , माउस , स्पीकर और प्रिंटर जैसे बाह्य उपकरणों कहा जाता है। Input Devices:- Keyboard, Mouse, webcam, Digital Cameras, pointing devices (Light-pen), Graphic Tablets, Scanner. Scanner is an input device because it converts Hard copy documents into Soft copy or Digital format. Output Devices: - Monitor, Speakers, Projector, Earphones, printers etc. Yes, Earphones are output devices, they give audio files(music) in output.  Peripheral ...
