Tips To Select Proper Hard drive
Day by day computers are getting advanced. Capacity and performance are increasing with every passing year. This is true for the primary storage also. Latest Hard disks are getting bigger in capacity and with higher rotational speed can access the data faster. This is good news for computer users. The digital revolution has brought with it the need to store vast amounts of data. The new Hard disks are ready to take the challenge. The good news is, these Hard disks with higher capacity are affordable. Thanks to a very competitive market and demanding consumers. Hard disk technology is suitable for the bandwidth demands of today's applications. The 7200 rpm hard disk drives with a minimum storage space of 40 GB and above are now more common than ever before. The demand for storage in PCs has boomed. With a lot of multimedia files being used today, including MP3, Flash files and movies-even today's entry level 40 GB hard disks aren't enough for users. On the other hand, 80 ? 400 GB, 7200 rpm drives are also available and are preferred by professionals. Depending on your need, you should select the proper hard drive. Ask yourself few questions, before going for the selection of new hard drive. This strategy will be useful in long run. Think of the following points. Hard drive storage capacity, speed, brand and price. First select the Hard drive storage capacity. 1) Also what software, you will loading in your computer. If you are a basic computer user, go for the 40 GB hard drive which is sufficient for OS and file storage. The text files require very less storage space however multimedia files require large storage space. If you are a gamer or a graphic designer, go for minimum 80 / 120 GB hard drive. If you are movie or song lover who would be storing lot of movies then go for higher capacity of 240 GB depending on your budget. Let us select the proper speed. The most common speeds which are available in the market are 5400 and 7200 RPM. The 5400 RPM means hard disk will be rotating at a speed of 5400 revolutions per minute. Now there is not much price difference between 5400 and 7200 rpm. It is better to go for 7200 RPM hard drive. It is better to go for standard brand. Seagate, Maxtor, Western Digital, Samsung & Hitachi are the standard brands available in the market. The above suggestions are for your internal hard drives. If you have to carry data frequently, you can go for external hard drive. These drives can be connected to computer through USB port. There is absolutely no difference between external hard drive and internal hard drive if you consider the operation or drive mechanics. USB interface has made external hard drive installation very user friendly. External hard drives give lot of portability. However these external hard drives have higher access time compared to desktop drive because of USB interface. But because of USB interface, CPU utilization is less in the range of 8.4 to 10. This means less load on CPU. Iomega, Freecom, Transcend are some of the manufacturers of external hard drives. These drives require external power supply and are most suitable for desktop use. When you are selecting external hard drive, check whether the manufacturer is offering a carry bag, data cable and power supply if it is externally powered. Also check the warranty offered by the manufacturer. Now a days, some of the manufacturers offer warranty for 3 years. Krishna Pai is a webmaster and a writer.

Computer Hardware Preventive Maintenance Software Computers often break down at the worst of all times. These problems can be averted, or at least minimized with preventive maintenance. Several methods of keeping computer hardware in good working order deal with the external components of the computer, such as the keyboard and monitor. For example, it is important to keep the processor away from excess heat and moisture. There are also computer hardware preventive maintenance software programs that can help with the upkeep of other internal aspects of a computer. Ten Tips to Safeguard Your Laptops The following is a list of tips to help safeguard your laptop while traveling or conducting business. How To Backup Your Hard Drive We all know that we should back up our system as soon as possible. But if you're like most of us, you will get to it tomorrow. The problem is that tomorrow rarely ever comes until you experience a serious computer failure and then it's too late. Getting A Great Refurbished Laptop Are you sick of all the high priced notebooks out there? Does getting a used laptop seem like a better choice to you? Refurbished laptops are everywhere these days, and the word itself seems like a "buzz word" of the industry. But do these used machines actually hold up to the strict standard of the word "refurbished"? Do You Have Dead Pixels? Take a good look at your notebook computer screen. Do you find some tiny dark spots? You could have dead pixels. One of the most expensive parts of your notebook computer is the LCD screen. USB Drive Popularity So many people have small USB drives today, but what is the attracting of owning one? A Guide to Refurbished IBM Laptops IBM boasts a very large array of older and newer refurbished laptops on their website ibm.com. Look for "Notebooks: IBM Certified Used Equipment." There you can buy any of dozens of models and variations, for hundreds of dollars less than new models. IBM inspects all of their returned laptops (including the batteries, as with most factory-refurbished laptops), makes sure they up and running at top speed, and repackages them for resale. Five Band Resistor Color Code-What Does The Last Band Of White Color Represent? In electronic repair, most of the time i came across five band resistor color code. The purpose of using the five colour band resistor in a circuit is that it provide a more accurate value compare to the four color band. For example in order to get the value of 22.6kohm, with four colors band resistor you will not be able to find it. The most you can get is 22k (red,red,orange and gold). If with the five color band you will be able to calculate it (red, red, blue, red, brown)the last color which is brown represent 1% tolerance. You may go to google search engine and type resistor color code, resistor color coding, resistor color code calculator, or resistor color code chart to know more about how to calculate a five band resistor values. Upgrading, Adding or Removing a Video Card, Sound Card, or Other AGP/PCI Card For Video cards - Most PC video cards these days are AGP. But you COULD be working with PCI, or PCI express. If you're not sure which you have (more then 75% of the time it will be AGP) consult your motherboard manual. If your video card is AGP, you should see a slot smaller then the other slots on your board, and it will be a different color. You can likely also tell your video card if it has a GPU (a processor with a fan on top of it) or a video card company printed on it like Nvidia or Geforce.

However, there are three common mistakes that people make that dramatically increase the probability of tape drive failure. What is EEPROM ? EEPROM stands for Electrical Erasable Programmable Read Only Memory and also referred to as E²PROM. As the name suggest, an EEPROM can be both erased and programmed with electrical pulses. Since it can be both electrically written into and electrically erased, the EEPROM can be rapidly programmed and erased in circuit for reprogramming without removing them from the circuit board. 5 Tips For Buying The Right Laptop Computer It's easy to be intimidated by all the laptop models on the market today. There are literally dozens and dozens in every price range. RAID Disk Recovery RAID is short for Redundant Array of Independent (or Inexpensive) Disks, a category of disk drives that employ two or more drives in combination for fault tolerance and performance. RAID disk drives are used frequently on servers and increasingly being employed on personal computers. Array is the operative word, which also dictates what the cure is going to be, when a RAID disk recovery situation arises. Your Hard Drive is Going to Explode ? Why a UPS is Essential It's most peoples worst computing nightmare. You wake up in the morning, flip on the computer, and it doesn't boot. Sometimes the problem rears its ugly head as a horrific clacking noise. Other times it simply gives a read error. Choosing a Tape Drive Tape drives remain the leading technology used by organizations for backup and archiving. However, the plethora of tape drives on the market can make choosing the appropriate tape drive a confusing task. How do you select a tape drive that satisfies your needs without blowing the budget? The following are just some of the main factors to consider. What is ESR Meter? All capacitors have a certain amount of resistance to the passage of AC current. ESR (Equivalent Series Resistance) is the sum of all internal resistances of a capacitor measured in Ohms. An ideal capacitor has ZERO ohms ESR. From the diagram below you can see a resistor in series with a "PERFECT CAPACITOR". The value of the resistor is called ESR. Electrolytic Capacitors have a tendency to increase its ESR overtime due to drying or corrosion. High ESR is a frequent problem in today's electronic circuit. Even a 1 or 2 ohms rise in ESR can cause complicated problems. Under normal conditions the ESR has a very low value, which stays that way for many years unless the rubber seal is defective, in which case the electrolyte's water component gradually dries out and the ESR creeps up with time. The increase in ESR increases both voltage drops within the capacitor and the heat, produced in the capacitors due to resistive heating. If you don't check for ESR, you may be in for a "TOUGH DOG" repair. High ESR is the first sign of a capacitor failure. High ESR will cause complete circuit failure, over heating of capacitor, loading of the circuit, overstressing of other circuit components and other undesirable effects. Computer Network Installation Computer network installation has become an essential prerequisite for any efficient modern-day business as it allows employees to truly work as a team by sharing information, accessing the same database and staying in touch constantly. For a computer network to give the best results, a lot of detailed planning and foresight is required before installation. Two Essential Accessories For Notebook Computers A Good Notebook Bag USB Hubs and Ports Explained The USB standard has become the universal means of connection peripheral devices and equipment to the computer. Computers have either two or four USB port connectors. Each of these can support a large number of connections but to be able to attach more than two or four devices requires a multi-connection hub. There are many different types of hubs and this article seeks to explain some of the important considerations in selecting the best choice of hub for your system.
