Advantages of External Hard Drive
Lesley Lyon asked: The computer component that holds data is a hard drive and an external hard drive is a hard drive that is outside the computer case in its own enclosure (also called hard drive cage). Every computer needs at least one hard drive to store its operating system, programs and user interpretation. It is usually internal but additional external hard drives have become indispensable.An external hard drive has become indispensable because there are potential security threats to our computers like virus due to Internet access even after employing anti-virus programs and firewalls. Apart from this, inadvertent corruption of sensitive documents and additional space required for multimedia storage are some of the problems and one single solution to all such problems is the external hard drive.The external hard drive is enclosed in an enclosure outside the main computer and is slightly larger than the hard drive itself and sometimes has a cooling fan. The external hard drive is connected to the computer through a high-speed interface cable, which enables the external hard drive to communicate with the computer by means of interfaces like USB and Fire Wire. An external hard drive is a very constructive piece of equipment in the sense [...]

Crazy From the Heat: Keeping Computers Cool
Richard n Williams asked: A computer’s components produce large amounts of heat during a PC’s normal operation. CPU’s, integrated circuits, graphics cards, hard drives and power supplies all generate heat through normal day-today working. This heat has to be dissipated to keep the computer’s components operating within their ideal operating temperature.Overheating can have catastrophic effects on a computers lifespan. S computer that runs too hot will have a shorter maximum lifespan and be more susceptible to system failures. CPU’s can even permanently expire if they run too hot.Excessive heat build-up can be caused by numerous factors (including the weather) and some computers struggle to remain cool due to their working environments. Computers having to run in warm areas or near to heat sources (like ovens and radiators) will often expire long before they ought to but there are several methods of keeping a computer running at an optimum temperature.Heat sinks are the simplest method of supplying cooling to a computer’s internal parts. Heat sinking is merely attaching large pieces of metal, which is usually finned, to increase the surface area and dissipate heatFans are also very common. A fan will allow air to flow through a computer taking warm air [...]
Computer Hard Drives and Repair
Kalin asked: The hard drive of your computer is an important component because you use it to store long-term data. It uses magnetic surfaces on which the data is stored digitally. In its early years the media was removable from the actual drive like the floppy drive and others but with time the drive and the media (the actual keeper of information) became one whole body. The writing and reading functions in the hard drive are performed by the head which is a small electro-magnet assembly. It is able to reach every sector of a disk in which the data is stored. There are many disks laid in a spindle which is used for a rapid rotation enabling the head to read and write data quickly. The rotation speed of the hard drive is one of its main characterizations. There are three interfaces on a hard drive which you will use to install it on your system. The first is the IDE connector. It is used for data transfer from and to the drive. Usually there is a red line which will tell you on what direction you should point the cable. The red line should always be on the [...]

10 Benefits of a Computer Enclosure Over an Industrial Computer
Richard n Williams asked: Demands are high for computing in industry. Industrial machines have to cope with many hostile elements whilst also providing reliable computing. Traditionally industrial computers have been specific, bespoke machines. These industrial computers tend to run old hardware and versions of software. Whilst this has the advantage of making the machines stable and reliable, the out-dated technology may mean the processes controlled by the machine are not done as efficiently.These machines are also very expensive, not just to buy but also the maintenance. Industrial computers have to be maintained by service engineer, often forcing shutdown of production lines they also have to be replaced periodically as the hardware and software will eventually become obsolete. All computers eventually fail but an industrial computer enclosure means that over three generations of computers can use the same enclosure.Industrial PC enclosures are a more efficient, affordable and reliable alternative to these expensive machines. The main benefits of an industrial computer enclosure are:1. Withstand the same environments as an industrial computer, whether that is dust (including explosive atmospheres), dirt, grime, oil, grease and water (even completely doused).

The Maintenance of Hp Hard Drive
Shawn paul asked: The workhouse of the computer is the hard disk. Therefore, it is important to know the functions and working of the hard disk. The files that we save are magnetically recorded onto the platter. The platter is placed inside the hard disk. The platters in most of the hard drives are usually mounted on a spindle. With the help of this spindle, the platter is able to spin faster and the speed can reach up to 15,000 times/ minute. The platter is two sided, and is mounted on a single arm which has a slider.The head can move across the surface with the help of the platter is two sided. In this way the head can read and access the data. The unit of data held by the platter is tracks/inch. The track is equal to 1 concentric ring around the disk. The track is further divided into sectors, and the sector is equal to approx. 512 bytes. The saved data on the disk is referred accordingly to its sector and track.The process of data collection can be made faster by de-fragmenting the hard disk periodically. The de-fragmenting can be done with the help of Windows Disk [...]
How a Computer Hard Drive Works
Duncan Kelly asked: A computer Hard Drive, or Fixed Disk, or HDD, is where all your data is stored when a computer is off. Because the data is stored magnetically, it doesn’t need any electrical power to retain or remember all this data.PHYSICAL CONSTRUCTION.The Hard Drive consists of usually one metal disk coated on both sides with a special magnetic material, usually an iron oxide compound, that has tiny particles that can be magnetically orientated to represent bits – which are the basic unit of computer memory, and are equivalent to a switch, being either on or off.This disk then spins at a very high rate of 8000 revolutions per minute or more, and then the two read/write heads that are used to actually retrieve the data from this disk, skim just a few hundredths of a millimetre from the surface of this spinning disk. The read/write heads are suspended on the end of metal arms that are able to move from the outer edge to the inner edge of this disk, so that they can seek out the data that is required. Very powerful rare earth magnets help control the rapid movement of these heads.HOW DATA IS STORED ON [...]

Laptop Batteries Replacement
Anmol Taneja asked: The actual life of a laptop battery varies according to the usage habits of the laptop. If your laptop’s battery is experiencing shorter life cycles then you have to identify if it needs a replacement or not. Both original new and repaired laptop batteries are available online and at stores – better go for a new one.The performance of a laptop’s battery depends upon its physical devices that require more electricity to operate. The hard drive, the floppy drive and the CD-ROM are the devices that sap up maximum power.The computational programs and the calculation processes used by spreadsheet applications and database programs engage the processor to a greater degree as well resulting in large consumption of electricity. Other physical devices that consume greater strength of battery are audio and display devices. The display panel also consumes lot of electricity. The brighter the screen appears, the more electricity it is consuming. Video applications also have an intense effect on electrical needs, due to its usage of virtual memory. Laptop batteries, like other batteries, start discharging faster as they age.Now if your laptop’s battery is giving frequent problems then go for a replacement. The best option is to [...]
Hard Drive Backup Solutions
Aaron Walker asked: Are you wondering if there’s an inexpensive way to backup the data on your hard disk? There is! While DVDs cost a bit more than CDs, they have so much more storage capacity that the extra cash is worth it. Many computers that are on the market today have DVD burners integrated into the computer from the start. This allows you to utilize this great backup storage option without having to spend any extra cash later on.DVDs are much better than the older storage options availe on the market before they became standard. The closest type of backup media to the DVDs were CD-Rs, but CD-Rs could only hold 700MB of information, which left them at a huge disadvantage. Besides the that, the biggest benefit of DVD storage is that you can very easily create multiple backups over a period of time without incurring a huge extra cost. If you need a new external hard drive every time you backup your system, you can imagine that the cost will go up fairly rapidly.You might have to purchase a DVD writer if your computer wasn’t fitted with one. If this is the case for you, then you should [...]
