How do i put password on my USB?
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.
How many address lines are needed to address each machine location in a 2048 X 4 memory chip?
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.
What are the two types of memory on a computer?
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
How many mega bytes are in 250 GB?
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.
What is the difference between a harddisc and RAM?
RAM is temporary memory, while hard disk space is more permanent memory.
When you save a file, you save it to your hard disk, but when you call up the interet, it uses temporary memory, RAM. The more windows you have open, the more RAM you will use up. Proccesses that the computer preform take up RAM, while saved files and programs take up hard disk space.
Hard disk space is usually a whole lot larger than RAM. For instance, a laptop may have 250GB (gigabytes) of hard disk space, and only 2GB of RAM
AnswerRAM is the computers memory, where as hard disk is the storage of the memory.information stored in RAM can be accessed and utilized much faster than information stored on a hard drive. The RAM is therefore generally used to store information in the short-term, for example for programs and processes you are currently running that will need a certain bit of information very quickly in order to function. The hard drive is generally for more long-term storage and for files which are required to run programs. When you run a program many files required for function may then be copied to RAM for use while running this
How can you determane the chipset if its not written on the board?
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.

Where do you insert your memory card in hp laptop?
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
Where The information stored in RAM is erased when the computer is turned off?
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.
How many bytes are there in 4 kilobytes of memory?
4,096 In computer memory, "kilo" refers to 2 to the 10th power, or 1024, rather than to 1000.
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.
