Computer Memory

speed

compatability

maximum memory allowed

ecc momory can detect and repair errors

This is probably the easiest thing you can do yourself on your computer. The good thing is that no matter if its a laptop or desktop, the RAM is in a easy to access spot.

First, find out the maximum amount of RAM your computer can handle, and then purchase the RAM.

Depending on your computer model, the steps will vary but there are some video tutorials that show step by step how you do it.

There are technically 1,440,000 bytes that make up 1.44 megabytes. The floppy disk that used to be used to hold data for a computer was labeled as a 1.44 mb disk, although it actually held 1,474,560 bytes.

Due to the recent floods in Taiwan, home to many of the world's largest Hard drive manufacturers. The simple HD is now becoming increasingly rare and expensive. A 1TB ( terrabyte = 1,000GB ) Western Caviar 7,200 RPM 6Gb/s HD costed about $99 less than a year ago. The current price? $249.99

Another expensive form of storage would be an SSD ( solid state drives ). They function the same as a mcechanical HD, except they have no moving parts and their acess times are approx 20 times faster than that of a mechanical HD. That being said they are also quite expensive, ( these drives were not effected by the flood ) with prices currently arround $2/GB.

RAM - Random access memory, storage for programs to store information.

ROM - Read only memory, very important information that is unlikely to ever need changing such as basic computer boot setup.However in ram viruses are easily to detect than in ROM.RAM is basically understood by the user and ROM is basically understood by the computer the command which is given by user is converted in such a language which can easily understood by the computer

volatile memory is memory that will wipe all the data saved to it after the computer shuts down e.g: RAM.

external cache or level 2 or L2 cache

No

1 Gb larger than 200 mb.

Flash Memory

Many of the new external hard drives have password/encryption software built in. Check the owner's manual first, to see if this is available for your drive. I recently bought a Seagate drive that not only has password protection, but also has a large amount of storage space, webbrowser, and can be set up with a files structure similar to the Windows environment. You can copy your computer's files to it automatically (with included software) and virtually carry around your own computer in a case about the size of your wallet.

It depends on how wide the data buses are on each chip, and how they're connected. If they're one byte wide, you could need over 256 million addresses, one for each byte. if they're wider, and connected to show an even wider combined data bus, it could be much less; around 32 million.

Internal and External. Internal - also known as Primary Memory, comes inbuilt when the computer is manufactured and mainly used to run the computer while external - also known as Secondary Memory can be added to the computer storing data and information for future use

Its simple anytime you want to figure out how many MB there are in a certain amount of GB you just know that 1GB=1024 MB. so take 1024 and multiply it by 250 which will give you 256,000MB in 250GB

Random Access Memory is also known as the Main Memory or the Internal Memory.

If the motherboard is working and computer is running, you can use third party software. I recommend CPUZ. It is light yet gives accurate information about cpu, motherboard, ram and others. visit www.cpuid.com to download the latest version.

Here is a list of Bits and Bytes

· 1 Bit = Binary Digit (ex 1001110)

· 8 Bits = 1 Byte

· 1024 Bytes = 1 Kilobyte

· 1024 Kilobytes = 1 Megabyte

· 1024 Megabytes = 1 Gigabyte

· 1024 Gigabytes = 1 Terabyte

· 1024 Terabytes = 1 Petabyte

· 1024 Petabytes = 1 Exabyte -

· 1024 Exabytes = 1 Zettabyte

· 1024 Zettabytes = 1 Yottabyte

· 1024 Yottabytes = 1 Brontobyte

· 1024 Brontobytes = 1 Geopbyte

Hello, For memory card to work we should have Card Reader installed in the computer...Most branded computers have them installed... If you do not have one installed on the computer.... Buy a USB all in one card reader which is compatible for most card's available(like SD, MMC, CF etc). Cheers, Sriram

Main computer memory is called volatile memory. It holds data only as long as it is provided power. When you turn off the computer, you remove power from the memory chips and they loose the ability to hold data. If you want to keep your information, ensure you save it to the computer hard drive before you switch off the computer.

4,096 In computer memory, "kilo" refers to 2 to the 10th power, or 1024, rather than to 1000.

Yes, you can but you have restarted your PC at least once you have a huge chance do restore your data at all. You might still try but software which you might need to restore usually shareware and you have to pay for that.

Through logical address the system identify a network (source to destination). after identifying the network physical address is used to identify the host on that network. The port address is used to identify the particular application running on the destination machine.

Logical Address: An IP address of the system is called logical address. This address is the combnation of Net ID and Host ID. This address is used by network layer to identify a particular network (source to destination) among the networks. This address can be changed by changing the host position on the network. So it is called logical address.

Physical address: Each system having a NIC(Network Interface Card) through which two systems physically connected with each other with cables. The address of the NIC is called Physical address or mac address. This is specified by the manficture company of the card. This address is used by data link layer.


Port Address: There are many application running on the computer. Each application run with a port no.(logically) on the computer. This port no. for application is decided by the Karnal of the OS. This port no. is called port address.
