Can you restore a data once you delete it from recycle bin?
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.
What are logical and physical address?
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.
What are the six categories of computer hardware?
The five categories of computer are:
- Super Computers
- Mainframe Computers
- Workstation computer
- Minicomputer
- Micro Computer
Supercomputer: A computer which, among existing general-purpose computers at any given time, is often in several senses: highest computation rate, largest memory, or highest cost.
Mainframe Computers: A large digital computer serving 100-400 users and occupying a special air-conditioned room.
Workstation computers: This computer has more computing capacity in its CPU than a typical personal computer.Scientists and engineers are the main users of workstations, although people who process graphics find a workstation necessary, since the processors can handle the huge amounts of data associated with graphic files.
Minicomputer: A mid-sized computer, usually fitting within a single cabinet about the size of a refrigerator, that has less memory than a mainframe.
Micro Computer: A personal computer
DQS = data strobe. When data is read from DRAM using the DQ pins, DQS is asserted so that memory controller can use that to read data. When memory controller writes to DRAM, it asserts DQS when DQ pins have the data to be written.
How many pages of text will fit into one megabyte of storage?
(second chronological answer dropped to bottom due to relevance)
3. A more exact answer may be found using some math:
First we'll assume that we're using 8.5x11 paper and the font Lucida Console size 10, which is a fixed font used by the latest Microsoft Notepad application. Second, we'll assume that the text is encoded using 8-bit encoding. This encoding is actually now antiquated, but it works much better for the math. New encoding methods use variable-bit encoding, so a page of one letter might be different from a page of another letter. The reason for the fixed font is that a page of i's will always be smaller than a page of W's unless the i takes the same space as W. With the previous conditions, one letter size page with 0" margins and standard spacing will have 79 lines of 102 characters each, giving 8058 characters per page.
On with the math:
8058 characters/page
8 bits per character
8 bits per byte
8058 bytes/page
1 KB = 1024 B
1 MB = 1024 KB = 1048576 B
1 GB = 1024 MB = 1048576 KB = 1073741824 B
Divide 1073741824 by 8058, and you find that one gigabyte can hold a raw
133251 Full Pages and 5266 Characters (or about 65% of another page). Note that the math gives the "raw" amount of text, which does not include any additional file information.
Hope that's definitive enough for you.
2. Well whoever wrote that last thing [Answer 1] really doesn't know what hes talking about,
if you want a lot of pages, with less storage, go find someone that will host your pictures, videos and files then just use the HTML, that way you save a lot of memory,
There are a lot of websites that host files like Mediafire and Filefront,
there is also some websites that host videos like Youtube,
I knew a few hosting services that host pictures, but I forgot most of them,
I think that ImageShack hosts them.
Anyways, once you upload them into any of those hosting services, you can copy/paste the HTML if the page supports HTML format.
This is how much space you will save:
100Mb video will be
15KB in your website if you use HTML
You will save a lot
A reply to answer 2:
The first response was a better answer to the question than the second response. The question was "how many pages of text can be stored in a gigabyte", not how many videos or pictures can be stored on a remote server.
If you have a 1GB thumb drive and zipped text pages, that would push the number up by a factor of 4 or more providing the documents were plain text.
Why your computer shows high memory usage?
The memory usage might be high because you have a lot of programs or tasks running in the background of your PC. To fix this right click your task bar and hit "Task Manager". From there go to "Performance" and see what is draining your memory. You will be able to end whatever program it might be from there.
What is the following smallest unit of measurement a terabyte megabyte gigabyte or kilobyte?
A kilobyte (KB) is 1,024 bytes; however many people think of it as 1,000 bytes.
A megabyte (MB) is 1,024 kilobytes; however many people think of it as 1,000 kilobytes.
A gigabyte (GB) is 1,024 megabytes; however many people think of it as 1,000 megabytes.
A terabyte (TB) is 1,024 gigabytes; however many people think of it as 1,000 gigabytes.
A petabyte (PB) is 1,024 terabytes; however many people think of it as 1,000 terabytes.
A The definition of an exabyte (EB) is 1,024 petabytes; however in some number systems it would be 1,000 petabytes.
Therefore, the 1 kilobyte is the smallest unit.
How is human memory similar to computer and how do they differ?
you mean how do a computer and the human brain correlate. in short, they dont. computers use only on and off states, the brain is vastly more complicated, the interactions based on chemical and electrical gradients rather than discrete values.
What is the function of memory unit of computer?
The basic function of memory is to store information.
It depends on the applications and programs that you will use. If you will use heavy programs like video editing tools and sound editing tools (After Effects for example), it can consume up to 16 gigabytes of RAM. Meanwhile, if you're only using small programs, 4 gigabytes is a lot. You can run several games without lag with 4 gigabytes of RAM. The higher the RAM, the better.
What is the named storage location in the computer's memory?
a variable is a named storage location in a computers memory for holding a peice of information
i have computer seince as my major ;)
Can your computer have 1.2 GB of RAM?
Yes and no...
Computer RAM comes in sizes which are powers of 2. It's possible to have one stick of RAM at 1024 MB and one at 256 MB for a total of 1280 MB. This is about as close as you can come to 1200 megabytes of RAM.
What is the difference between PC-5300P and PC-5300E ram?
The PC2-5300U is non-ECC Unbuffered RAM, which is the most common type of RAM that does not check for errors. The PC2-5300E RAM is ECC RAM or error correcting. The two will not work together. ECC RAM will only work in motherboards that support it. The E and U at the end of the names indicate the ECC and Unbuffered status Insert mode
.
The question was about 5300P, not 5300U memory.
The 5300P memory is registered with Parity whereas 5300E is unbuffered. That means there is no buffer (or register) which holds the data temporarily to additionally help with data integrity.
It is integrated with Processor. Also called Cache Memory.
Yes RAM can be modified, but to be able to do so you need to get a stick of RAM or a RAM card which can be bought at most stores. A good place to find RAM would be a site called NewEgg.com. After you get the RAM card you will have to open up your computer case and find what are commonly known as expansion card slots. They will be noticeable, as they will be on the motherboard itself and will look like rectangular slots.
Where can one get their Mac Mini RAM upgraded?
Mac Pro memory upgrades can be downloaded direct from the Apple site. There are several third party resellers who also purport to sell memory upgrades but care should be taken when downloading form an unknown site to be wary of malware.
Can you put pictures that are on your computer on to an SD memory card?
Yes.
Place it in the card reader (you may also be able to use your camera for this, but if it doesn't work, don't blame us).
Find the card in My Computer. It will show as a removable drive.
Click on it. A window will open showing the contents of the card.
Drag and drop the images onto the file window. They should transfer to the card just fine.
What is meant by the term Maximum addressable memory?
Maximum addressable memory is the most information a computer can store without having to delete something to make room for space. The maximum addressable memory also takes into consideration the files that cannot be erased, like the operating system files.
Is any long-term data stored on ram?
Not unless you power it permanently. RAM can only store data as long the power is turned on.
How much memory does the average computer hold?
It depends on how large your hard drive's capacity is. A 1TB (terabyte) hard drive can store 1,000GB (gigabytes), 1,000,000MB (megabytes), 1,000,000,000KB (kilobytes), or 1,000,000,000,000B (bytes) of data.
What is the smallest unit in a computer's memory?
A bit, which can hold two values. 1 bit is the smallest unit of info in a computer 4 bits = 1 byte 2 bytes = 1 word a "byte" can be all sorts of things: It usually is the smallest addressable unit in a computer. 8 bit bytes are the most common nowadays, but here are, or have been, computers with bytes of 4 bits, 8 bits, 9 bits, 13 bits, 16 bits and others.
The smallest amount of data that can be stored on a computer is a byte. A byte is one character, whether a letter or number. Computers store data in numbers, mostly 0's and 1's, which represent on and off.
A 32-bit processor can perform functions on 32-bit pieces of information. The value of that 32-bit number may only be 1 bit, but the computer processes it as if it were 32-bits.
