4 GB PC2-5300 DDR2-667 memoria de la computadora (RAM) 200

Basic Terms to Learn About Computer Memory

Without a computer memory, we wouldn't be able to save our files. We would always have to keep the computer on. Memory is extremely important for data storage.

What is a computer memory?

A computer memory is a physical device capable of storing information either temporarily or permanently. There are two main types of memories. The random access memory (RAM) and the read-only memory (ROM). These are the types of memories that enable you access information stored on your computer.

What are DIMM slots and what are they used for?

Dual in-line memory module (DIMM) is the long slot arranged in groups of twos, threes or fours on either side of the CPU. Their purpose is to hold your memory (RAM) blocks.

They comprise a series of dynamic RAM integrated circuits. The modules are mounted on a printed circuit board, which is designed for personal computers, servers, and workstations.

What is the difference between DIMM and SODIMM?

Both DIMMs and SODIMMs are memory modules used in computers. DIMMs are useful in desktops and servers. DIMMs are about 133mm about twice as long as a SODIMM which is approximately 67 mm. DIMMs carry features such as ECC and REGISTERED which are not normally found on SODIMMs.

What is DDR2-SDRAM?

Double data rate synchronous dynamic random-access memory (DDR2 SDRAM) interface, supersedes the original specifications of DDR SDRAM. The DDR3 SDRAM, which was launched in 2007 superseded the DDR2 SDRAM. The DDR2 SDRAM is neither compatible with DDR3 nor DDR.

PC2-5300 is a DDR2-SDRAM memory at 333 MHz in 200-pin SO-DIMM form-factor. It is also called DDR2-667

What is the difference between the DDR2 and DDR3?

DDR2 RAM will provide you with four data transfers each cycle, while DDR3 increases the number to eight. Assume you have a base clock with a speed of 100 Mhz, DDR RAM provides you 1600 MB/s of Bandwidth. DDR2, in this case, will provide you 3200 MB/s, and DDR3 delivers 6400 MB/s. So the more the better.

DDR2 DIMM is not backward compatible.

What is ECC Memory?

Error correction code (ECC) RAM is popular in servers and systems with high-volume data. It protects the computer against data corruption as it automatically detects and corrects errors. A standard RAM uses eight memory chips which stores and provides data to the CPU on demand.

What are the different local storage options?

Below are some of the different type of storage options.

• Cloud storage
• USB thumb drive or flash drive
• Optical drive (DVD/CD)
• Solid state drive (SSD)
• Network attached storage (NAS)
• External hard drive. They are similar to those installed on a laptop or desktop computer

What is the difference between unbuffered and buffered memory?

• Buffered- A buffer helps the system control a significant amount of memory.
• Unbuffered- There is no buffer. The memory is connected to the chipset controller. DDR, DDR2, and DDR3 used on desktops are unbuffered.
