Where is a byte's temporary storage location in memory?
A byte's temporary storage location in memory is RAM. The process of translating instructions into signals the computer can execute is a tower.
What formats does a DVD player play?
It depends upon you DVD player. If you have simple DVD player then it will play mpeg2 format which are in the .vob files and ac3 which is audio format. It should also play the mpeg1 format which is usually in .dat or called video cds. The new DVD players also support xvid or divx codecs.
Do I use a CD or a DVD to store photos?
It depends primarily on how many pictures you intend to store on a single disc, the size of those pictures and where they will be viewed. Choosing one of the other will have no impact on the final quality of the pictures.
While a DVD will hold several times the number of pictures of a CD, CD's can still hold a fair number of pictures. If you can fit all of the pictures you need onto a single CD, you are a little better off going with the CD. The reason is that most DVD players and DVD drives will read a CD, yet CD players and CD drives will not read a DVD. If you are sharing these pictures with someone that may only have a CD drive and not a DVD drive, the CD will give you greater compatibility.
If you have too many pictures to fit on a single CD, you would still be okay sharing a DVD in most circumstances. Almost all drives installed in new computers over the past 7-10 years have been DVD drives.
I think the DVD is better than CD, becaus of the better quality and bigger capacity...so if you want to burn more pictures onto a CD or DVD, you had better choose the DVD disc, hope these informs can help you.
How does an external hard drive work?
Think of an external hard drive like a normal hard drive working outside your computer, they work very much in the same way. Normally (unless you are using a SCSI, PATA, or eSATA hard drive), they can be connected to your computer via a Firewire or USB connection. If you have a key-drive (aka USB memory stick), they work like a miniature external hard drive in the sense that they store date in an external format; an external hard drive is just like a large key-drive. With both a key-drive and an external hard drive, you simply connect it to your computer, and access its files. When you want to access your internal hard drive, you go to My Computer and then select the C: drive; The external hard drive is a similar process, you select it's icon (located either on the desktop or My Computer) and then you can access its files like a normal hard drive. You can drag files out of it onto your desktop, or alternatively, drag files into it to transfer files from your computer.
What kind of secondary storage does flash memory card belongs to?
There are two types of memories: Primary and Secondary.
The primary memory or the main memory is part of the main computer system. The processor or the CPU directly stores and retrieves information from it. This memory is accessed by CPU, in random fashion. That means any location of this memory can be accessed by the CPU to either read information from it, or to store information in it.
o The primary memory itself is implemented by two types of memory technologies. The first is called Random Access Memory (RAM) and the other is read only memory (ROM). A more appropriate name for RAM is RWM (Read Write Memory), the CPU can write and read information from any primary memory location implemented using RAM. The other part of primary memory is implemented using ROM which stands for Read Only Memory.
Primary memory is much faster and also it is more cost effective. But the secondary memory is much slower and also less costly. It stores the data permanently unless it is erased. The secondary memory is usually available in the form of floppy disk storage media, hard disk, CD, DVD, Pen drive (i.e. Mass storage devices), memory chips. A 5 and1/4 inch floppy disk typically stores 1.44 mb of data. The data on the floppy disk is organized in terms of tracks and sectors. Hard disk can have large capacity something like 80-300 GB's or higher. Hard disk itself is made up of, large number of platters. Hard disk is usually much faster compared to floppy disk. CD can store up to 750 mb of data. Information on CD ROM is organized in terms of a spiral track. A DVD is digital Versatile Disk and can store 4.6 Gigabyte of information. All these CD disk are usually write ones and read many times (if the disk is not multisession and re writable). So are the DVDs.
so as a conclusion, pen drive is a secondary type of memory, since it is a peripheral device and needs to be connected to the computer to retrieve the datas.
When and why would you use floppy disk?
To store small documents or DOS (Disk operating system) programs
It's an output. I think.
The usb port is already in there, so it should be an output.
An input is something you put in, and an output is something that comes out.
Hope this helps. :)
Are optical disk disks are random access storage devices?
floppy disks are read/write storage devices, they are a backing store, a non-volatile long term storage which will not lose data when power is lost.
Random access storage is the original term for RAM, the random access memory term was used a a marketing term and has stuck since.
Another Answer
YES - floppy disk are Random Access storage devices.
Is pen drive magnetic media or optical media?
Neither - they are a Solid State Drive (SSD). They use silicon chips to store the data - in general similar to RAM except they are Nonvolatile - they retain data without any power applied whereas RAM is Volatile and losses all it's data when power is removed.
How do you remove the hard drive from a Gateway M305CRV Laptop?
Shut down the laptop. Turn over the laptop and you will find a small panel with a Hard drive sign with 2 screws on the panel cover. Unscrew the cover carefully and pull out the HD very carefully. It's very simple.
In what kind of machine is a floppy disk used?
The floppy disk, both the original 8 inch size and the later 5 1/4 inch size were used in all sorts of relatively early computer equipment.
- To distribute and load firmware in a model of the IBM System/360 mainframe.
- For software distribution as well as backup/restore media for the IBM System/38 and various other model midrange computer equipment.
- For software distribution and data storage on a Digital Equipment Corporation (DEC) PDP-11 system.
- For data storage and various word processing machines.
- As system devices and data storage for the original IBM Personal Computer and other similar personal computers.
Its use was replaced by the 3 1/2 inch diskette when it became available.
How do you find HDD in the BIOS?
If you're installing a new hard drive bios should automatically see the drive on start-up, if not go into set-up and option it for auto. As to how to get into set=up watch the boot-up screen, usually you press delete or f1 key. After changing the settings hit f10 and say yes to save the settings for your hard drive and reboot.
Why is the hard drive called c?
In the old days, computers had floppy drives. They usually had two, so you could put a program disk in drive A, and a data disk in drive B.
Later computers kept two drives so they could support both formats: 5 1/4 inch, and 3 1/2 inches. By this time, hard drives were universal, and almost always installed as the C drive.
AnswerOriginally, computers used floppy drives. The first drive was called "A:", then computers had 2 drives, A and B.Then... hard drives
Is a CD-RW or DVD Drive a hardware device?
Yes.
CD-RW and DVD drives can be either internal or external hardware devices.
What is th purpose of secondary device?
Secondary storage device is USB and also the external hard disk are external devices these are best for external memory.
Which is more stable raid implemented by windows or raid implemented by hardware?
Raid implemented by Hardware is more stable than RAID implemented by Windows
What is the part of the computer that contains the hard drive?
The hard drive is usually installed inside the computer case. Some refer to this as "the box" or "the system unit."
Some even refer to this part of the computer incorrectly as the CPU. That is due to misunderstandings and in some cases, carryovers from the old days. The central processing unit was not a single chip like it is now, but a collection of many chips and transistors which spanned multiple circuit boards. So in the early days, all those components collectively made up the CPU. Now, the CPU is a single chip, and most of the other components are included on the motherboard, and they all make up the system unit which is together inside the case.
What is the device that reads and records information on disks?
Head – The device that reads and writes the information—magnetic or optical—on the disk surface.
What are data scanning devices?
A scanning device is something that looks over a surface and can transfer information. Scanning devices are used to tell you the price of things for example.
Is optical storage a nonvolatile storage device or a volatile storage device?
It is nonvolatile, if you turn off the computer, the disc is not erased. (if you have a dvd bluray or cd and you turn off the cd, dvd, or bluray player the songs or movie on the disc is not erased). It does not use electrons to store data, it uses grooves and bumps in the disc and is read with a laser
What is the best writing speed to burning DVD?
Faster times can be a little less accurate, so slower times have a better chance of uncorrupted data
