What devices held information before memory sticks?
Floppy disks were often used before USB or memory cards existed. It was the main form of saving data at that time.
What kind of software scans a computer's hard disk floppy disks and main memory to detect viruses and sometimes destroy them?
Antivirus programs, ex. Norton, Symantec, BitDefender, Avast.
Differences between a floppy disk and a hard disk?
A floppy disk is a flexible and magnetic data storage system that is removable from the computer that can store up to 3 megabytes of data. A hard disk on the other hand is the main place that a computer stores data. It is a rotating disk that uses magnetic patterns to store data. Floppy disks have been replaced by USB flash drives.These days (2012) you will not find many floppy disks (although just a couple of years ago we had to order special floppy drives for a server because some software would only be installed if it booted from Drive: A a floppy). There were 8 inch and 5 inch and 31/2 inch floppy disks which were common. The latest (diskettes) were the smallest and were protected by a hard plastic casing. Inside a thin Mylar disk coated with a magnetic surface stored the 1.44 Mb that was the capacity of most diskettes. Hard disks have one or more aluminium or glass disks coated with magnetic surfaces. These hold much more information and now (2012) there are units that can store 3Tb or more.
What are the Main advantages of hard disk drive?
its a storage device, it stores information
What are the regular PC consumables?
The main PC consumables are paper, toner cartridges, and inkjet cartridges. These consumables are usually used for printers. Other consumables may include floppy disks, pen drives, and CD/DVDs.
Why is hard disk is popular than floppy disk?
Hard disk is more popular than floppy disk because hard disk can store huge amount of data in term of mega byte to giga byte. It stores the data safely compared to floppy disk. External hard disk are portable so they can transfer the data from one computer to another . But floppy disk has low capacity and are vey slow compared to hard disk . It can be easily damaged when exposed to heat and dust. Files can be easily corrupted and data transfer rate is slow compared to hard disk. Nowadays, computer are built without floppy drives which is needed to read floppy disks.
What are the main categories of optical laser disks?
Main categories of optical laser disks are CD-ROM,WORM Disk/CD-Record able(CD-R) Disks,CD Read/Write(CD-RW) Disk,Digital Video(or Versatile)Disk(DVD).
What is the main advantage of using a web query to get information?
The main advantage of using a web query to get information is the ability to retrieve real-time data directly from a website or online database without manual data entry. Web queries can automate the process of data retrieval, saving time and reducing the risk of errors associated with manual extraction.
What is the main advantage of it?
You are not specific enough. The main advantage of what? It does not make any sense.
What is the difference between floppy disc and hard drive?
A hard disk (HD for short) and floppy disk (FD for short) both work in the same manner, except that on can hold more information. Both are a type of magnetic media which can have information written and erased many many times. A lot better than paper when you write something and erase many times, that paper gets thin, then GAME OVER! I am including a link to better explain this from "howstuffworks". I really love that site. I could spend all day on there reading about anything! About their differences. the most common floppy disks only hold about 3.14MB of data. Where an electric HD can hold almost any amount up to several terabytes today!! That is huge. The FD uses a mechanical motor to move the read/write armature that hovers over the FD material (most comparable to cassette tape material). This is where it changes the magnetic properties of the tape material, and bingo, last night's report is saved! The HD works in a similar fashion. HD's have dense metallic disks inside that can spin at thousands of RPM's (rounds per minute). As the disks spin a similar Armature that is is surrounded by some really powerful magnets changes the magnetic properties of the dense metallic disks and Bingo, last night's report, music, and the whole operating system is spinning virtually forever. That is the basics. Hopefully that sums things up in a nutshell. Visit that site at howstuffworks to really see a more in depth look at floppy disks & hard drives!
Can people still use floppy disks and with kind of computer?
The short answer is no. They really aren't of any use any more. Long answer: There are still quite a few old machines that have a slot for the second generation floppies, the 3 1/2 inch disks. You just have to keep asking around for access to an older machine, even, for example, a laptop or desktop computer from 2005 might have such a slot. These 3 1/2 inch floppies replaced the original floppy disks which were 5 1/4 inch floppy disks. Quite hard to find a machine that has a slot for one of these. But, just as there are people that like to play old 78 RPM records on their old machine, there are a few that still have an ancient - 1980's - computer set up that will run the old floppies. Only the real old timers of the computer age have used them. Back then a hot computer had 640 kbyte of RAM. Hardly anyone had a HD so there were usually two slots for these, the A Drive and the B Drive. To this day most computers call their main drive C Drive and this is the reason. Good luck finding someone that has a machine that can read your floppy!
The main advantage of ECL over TTL?
The main advantage of ECL over TTL is speed.
