How much RAM do you need to watch videos on your computer?
There's no precise answer to this. The requirements will depend on the resolution of the video, the codec used, the software used, and whether you are watching in full screen. A standard resolution DVD should be playable in full screen on a 233 MHz Pentium II with 32 MB of RAM.
How many movies can fit on a 2 terabyte hard drive?
Approximately 2000
(More like 200 or 100 if you rip the whole thing)
I just ripped 105 movies, and they took up 366 gigs. I only copied the main movie, and not any other features or menus on the DVDs. Also, maybe about 5 of them were only about 25-30 minutes long, while most of the rest were full length movies. This is straight ripping without compression.
What does are giga bytes mean?
A giga byte is size there are 1024 mega bytes in a giga bite. Useally an avi format movie is 800 maga bytes and a song is 6mb so you can work out what you need from there
1,000 Kb is 1 Mb, so 21,000,000 Kb is 210 Mb. Barely enough to run an operating system. If you see this number on any of your drives as spare space, it's time to add another one.
How many kilobytes are in a gigabyte?
There are actually two answers to this, depending on what method you want to use to determine the answer.
Standard definition The standard definition for kilobyte is 1,000 (10^3) bytes, just like there are 1,000 meters in a kilometre.
Likewise, the standard definition for gigabyte is 1,000,000,000 (10^9) bytes. Dividing, this means there are 1,000,000 (1 million) kilobytes (kB) in a gigabyte (GB).
This is the definition used for hard drives, portable memory drives (memory cards, USB drives), DVDs, Blu-ray disks, and most measures of performance. Some software (such as Mac OS X and the Linux kernel) uses this definition when displaying file and disk sizes. Memory manufacturer usage Memory manufacturers use a non-standard system that conflicts with the way everyone else measures. By their definition, a kilobyte (written "KB") is 1,024 (2^10) bytes, and a gigabyte (written "GB") is 1,073,741,824 (2^30) bytes.
The correct name for 1,024 bytes is "kilobinary byte" or "kibibyte". The correct name for 1,073,741,824 bytes is "gigabinary byte" or "gibibyte".
This is approximately equal to the above, but you may need to know it to figure out exact numbers:
By this definition, 1 "GB" = 1,048,576 "KB" More correctly, 1 GiB = 1,048,576 KiB
This definition is used by memory manufacturers and some software, like Microsoft Windows.
How do you clean off your computer's hard drive?
Externally
Wipe down with a damp cloth (not wet). Vacuum the air vents.
Internally.
Switch off and remove plugs. Remove covers. Use a clean dry paint brush to loosen fluff and dust, whilst holding the end of a vacuum cleaner close to the brush. Do not touch any of the components with the nozzle. Pay attention to the cpu heatsink and power supply fan vents.
Software.
Remove any unwanted programs using the removal program that came with the software, or use windows add/remove programs in control panel.
Delete temporary files, with extension *.TMP
Find and delete copies of files.
Defragment disk drive.
Use a clean up tool, either in windows or another such as CC cleaner.
How much difference is between 1.0 GB ram and 4.0 GB of ram?
First, four gigabytes of memory is more than one gigabyte. Four gigabytes is also the maximum amount of memory a non-PAE 32-bit computer can handle, but most modern systems now support PAE. Having more memory on your computer can also improve performance by minimizing the amount of page swaps needed to your pagefile or swap partition.
How do you free up memory on Windows XP?
1. Right click on an empty spot on your desktop and select New - Shortcut. 2. Type %windir%\system32\rundll32.exe advapi32.dll,ProcessIdleTasks in the box. 3. Click Next. 4. Give your shortcut a nice name like "Clean Memory" 5. Click Finish and you're done. Now whenever your computer starts running slow click this shortcut to flush everything out of memory
What is bigger than 1 terabyte?
- 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 - In 2000, 3 exabytes of information was created
- 1024 Exabytes = 1 Zettabyte
- 1024 Zettabyte = 1 Zottabyte
- 1024 Zottabyte = 1 Brontobyte - that is a 1 followed by 27 zeroes
all computing memory is in base 2
It really depends on weather you're asking a manufacturer or a computer.
MP3 manufacturers use 1gb = 1,000,000,000 bytes.
Computers use 1GB = 1024MB = 1048576 KB=1073741824 bytes.
So to answer your question, it is either 1500 MB and 1,500,000 KB or 1,536MB and 1,572,864KB
What part of the computer keeps it memory when the computer is off?
The hard drive keeps all your files and goodies
To summarise all the previous answers - its the shareholders.
A microprocessor has 24 parallel address lines How many memory locations can the processor address?
32 bit address line can access 4GB of memory. As 2^10 -> 1KB; 2^20 -> 2MB; 2^30 -> 1GB and so on.... 32 bit gives (2^30) * (2^2) = 1GB * 4 = 4GB;

How many RAM slots does a notebook have?
I agree with Rtrahan that most laptops have two RAM slots (though I have seen some that have three or even four slots but those are usually gaming laptops rather than run-of-the-mill machines). However, he is incorrect that both slots have to be used. Instead, many laptops actually come with a single RAM stick and leave the additional slot open for the user to add more RAM if/when he decides to do so. The only concern is to make sure that the speed of the RAM that is added later is the same as what is already in there. If the added RAM is faster, then it will be slowed down by the original stick of RAM and you have just wasted your money on speed that you can't use. If you, instead, get slower RAM that what is already installed, then you will be bottlenecking your machine because now the original RAM will have to slow down for the new RAM, thus degrading performance.
One kilobyte equal approximate how much memory locations?
The answer to this question depends on two key factors, the definition of a kilobyte, and that of a memory location:
First, is kilobyte meant in the standard engineering meaning of a multiplier of one thousand, or is it mean to represent a factor of 210, commonly known as a kilobyte, but more correctly called a kibibyte?
Thus, one kilobyte can mean 1000 bytes, or 1024 bytes.
Second, what is a memory location? Most memory types have a bitwise organization, so 1000 or 1028 bytes would refer to 8000 or 8196 bits, respectively, and refer to 8000 or 8196 memory locations thus.
Other implementations of memories may implement a different granularity, for example based on 16, 24, 32 or even larger number of bits per location.
SIMM (Single Inline Memory Module), is a form of RAM (Random Access Memory) It is a ram chip with memory chips on one side. A DIMM (Dual Inline Memory Module) is like a SIMM, but has memory chips on both sides.
Is secondary memory directly accessed by CPU?
No, secondary memory is not directly accessed by the CPU. Instead, data from secondary memory (like hard drives or SSDs) must first be loaded into primary memory (RAM) before the CPU can access and process it. This distinction is crucial for understanding how data is managed in a computer system, as secondary memory is significantly slower than primary memory.
How much is a kilobyte and megabyte?
1000 kilobytes are in a megabyte and 1000 megabytes are in a gigabyte.
These are the storage industry standards.
However, megabytes as displayed by an operating system are actually measured in binary form, thus 1,024 kilobytes are in one megabyte, and 1,024 megabytes are in a gigabyte.
There are 1,048,576 bytes in a megabyte, and 1,0458,576 kilobytes in a gigabyte.
This is one reason why your operating system will claim that there is less memory on your hard drive than what the manufacturer claims.
Is it possible to install the RAM backwards?
It does not matter what direction you install something, it'll even work upside down.
