There are numerous ways to backup data. Most people have an exterior laborious drive and replica their documents and photos across to it every now and then. Or you might need some backup software program working that automates the process. The issue with these solutions is that the exterior hard usually sits on the same desk where the PC is located. If there’s ever a break in and the PC is stolen, there is a good probability they will swipe the external hard drive as well. Likewise if there is a fire, it will doubtless engulf your PC and backup onerous disk.

A NAS drive, or Network Area Storage drive permits the exterior exhausting disk to be situated elsewhere within the house. Because its bodily in a different location the possibilities of it being stolen or broken concurrently your PC are significantly reduced. Especially if you get artistic and position in a spot that’s tough to spot.

As a way to hold price down, many NAS drives do not have wireless capabilities and depend on an ethernet cable which connects the NAS to your property modem/router. From there it may be accessed by all the other PC’s and cell units within the house. However in case you spend a bit extra and get one with wi-fi functionality, you’ll be able to have more flexibility as to where you position it within the house. As long as there’s a power level nearby, it could go anyplace including on prime of kitchen cupboards, hidden within the bedroom, or wherever you possibly can think of that’s securely away from sight.

One other advantage of NAS drives is inbuilt redundancy. The fashions that maintain onerous disks usually offer RAID 1, which means that every disk is a duplicate of the other. So if one disk fails, the other is still available. If you replace the faulty one, it rebuilds itself and information is ever lost. Larger NAS drives that hold four or extra arduous disks offer RAID 5. Raid 5 requies a minimal of 4 laborious disks and one is used for redundancy and whole of the remaining disks is your accessible disk space.

If a house or enterprise has more than one PC and a lot of cell units corresponding to good telephones and moveable media gamers, the NAS could instead be used as a central repository the place all these units can entry and use the identical data. As a result of the NAS makes use of less power than a PC, the whole lot else in the house can still use the info with out the PC having to be on, due to this fact saving on energy costs. For instance you might need to show mates some pictures on the TV, and with the pictures stored on the NAS there isn’t any must boot up the PC.

These NAS finest practices are just a few issues you are able to do with network storage. Some also have in-built BitTorrent clients, or they may have DLNA which permits media streaming. However the perfect thing they do is enhance the security of backups. Configured correctly and safely positioned in the home, a NAS drive supplies additional peace of thoughts that your data is securely backup up and separated out of your everyday PC.

Tablets, tablets, tablets…but which one?

September 9, 2010 admin Phones/Tablets No comments
Written by Olivia Preston

 

Tablets are a cross between a smartphone and a laptop and are currently the most sought after device in the tech world right now.

So far, the Apple iPad has been the only mainstream contender for the number one tablet after selling over two million in the first two months of its release, but with the release of the Samsung Galaxy tab, and copious amounts of other anticipated tablet launches, Apple may be forced to hand over the tablet crown.

Tablets are no doubt going to be this year’s most popular gift for Christmas, but how you do the impossible task of choosing which one to buy if you’re not particularly tech savvy?

We’ve reviewed some of the current and up and coming tablets on the market so the all important decision can be that little bit easier for you.

All tablets allow users to browse the Internet with their fingertips, flick through photos, read e-books and even watch films but which tablets really stand out from the crowd?

Apple iPad

The iPad has a 9.7 inch backlit LED touchscreen, a screen resolution of 1024 x 768, and weights 1.5 pounds. It also has up to 10 hours of battery life.

The iPad offers Wi-Fi + 3G superfast data speeds of up to 7.2 Mbps over the 3G mobile networks so users can access the Internet wherever and whenever they need to.

Users can access over 25,000 apps available from the Apple app store, the interface is very user friendly and you can also use the iPad to watch TV. Bluetooth is enabled to send and receive data for free.

The cons are that the iPad doesn’t support Flash, which is a shame. This means that websites using this will be shut off to iPad users. The battery is also built in so if anything goes wrong, it will be costly to fix. There’s also no camera or USB port.

Price: Starts at £429 Release date: Out now

Samsung Galaxy

The Samsung Galaxy has a smaller touchscreen than the iPad at just 7 inches and weighs just 13.8 ounces. The screen resolution is a bit lower than the iPad at 1024 x 600, but the dots per inch are higher.

Unlike the iPad, it can be used as a phone, also has a 5MP camera and can support Flash. Its battery life is slightly less at just over 9 hours.

Google Android is a big selling point for the Samsung Galaxy and could clinch the sale for many fans of this operating system which also runs on smartphones such as the HTC Desire

Although only around 200 apps will be available at launch, the price is anticipated to be a lot cheaper than the iPad.

Price: TBC Release date: November 2010

Toshiba Folio 100

The Folio 100 is Toshiba’s entry into the tablet race, opting for a 10.1 inch touchscreen and weighing nearly twice as much as the Galaxy at 1.6 pounds.

The battery isn’t as impressive as the Galaxy or the iPad at 7 hours, but comes with the Android OS, is Flash compatible, 16GB flash storage, Bluetooth, a built in 1.3MP webcam, SDHC card slot, HDMI, a USB port and audio jacks.

It’s not as aesthetically pleasing with its plastic casing as the Galaxy or the iPad but is considerably cheaper.

Price: £329 Release date: October 2010

Fusion Garage JooJoo

Made by Fusion Garage, the JooJoo has been slated by tech reviewers for its tiny battery life at just 2.5 hours and its uninspiring user interface and lack of apps available.

It has a larger screen than the iPad at 12.1 inches, a screen resolution of 1366 x 768 and it boots up in just 9 seconds. It also has a front mounted camera and a USB port, which the iPad does not.

It’s very clear that the JooJoo is in need of a few tweaks here and there but reviewers have given this iPad alternative far too much of a hard time. After all, it supports Flash, looks sleek and is great for browsing the net whilst on the move.

Price: £374 Release date: 2011 but already available in the US

Archos 10.1 Android

The French electronics company has jumped on the tablet bandwagon recently launching five tablets, one of them being the Archos Android tablet. The tablet has a 10 inch screen, weighs just 16.9 ounces and is 12mm thick. It has its own app store (appslib.com) with a sizable choice of 5,000 apps to choose from, has an Android OS, is WiFi enabled and comes with Bluetooth.

Its very easy on the eye with its stainless steel structure looking slick, has a front mounted camera, and a built-in leg stand. Other features include USB port, HDMI output, HD video playback and a MicroSD card supporting up to 16GB.

At over £150 cheaper than the iPad, this will be a serious contender for the most popular tablet.

Price: £269 Release date: October 2010

So, as for which tablet to go with, I personally would go for the Samsung Galaxy or the Archos 101 Android tablet depending on your budget.

I certainly won’t be purchasing an iPad until all of its issues have been sorted out which won’t be until iPad 2 is released during 2011.

Which antivirus protection is the best?

There are a currently plenty of anti virus protection on the market for you to choose. The leaders are pretty obvious and they are MacAfee and Norton but they may not definitely be the best anti virus protection available. The needs of individuals and corporations vary and different software can meet the needs of different folks. You need to do a self-assessment before you can really decide on the best option for yourself.

The most rudimentary specifications that must be available for any

antivirus protectionsoftware is protection against phishing, virus, spyware, malware, Trojans, adware etc. The antivirus tool must be able to shield your computer from the latest virus or malware and if you are a commercial user, you would probably want your company-wide computer systems to be protected with the best security. To this end, the antivirus tool must have the full range of security available and it must be updated to the latest threats. New viruses are released everyday and an annual timeline for updating is not the most appropriate schedule for anti virus software. A yearly update will mean that you are only protected against last year’s viruses.

The best antivirus tool should have a good firewall to keep out unwanted traffic from suspicious external servers and systems and it must be able to stop your own applications from uploading non-authorized information or data, which can compromise your PC. However, this firewall must not slow down your system or internet speed else the effort would not be justifiable.

When you are comparing different antivirus tools, take note of what are your personal Internet habits or how are the people in your company behaving online. This information will assist you to decide which antivirus tool will meet your requirements. If you do not download files or torrents regularly, your protection needs could be lesser and can survive with a simple antivirus with an email scanner. You can also make do with the Windows firewall but if you are a heavy user who downloads torrent files from unsavory sites, you should invest in an industrial grade antivirus tool.

What is RAM?

Written by Tom Paine

 

RAM is a moniker for Random Access Memory. It acts as a short-term memory much like the human brain to store a wealth of information. The RAM is accessible through the computer’s brain called the CPU which stands for Central Processing Unit. RAM has the capability of being retrieved only while a computer is on. When the computer is turned off the RAM is no longer accessible. ROM chips along with BIOS (computer boot firmware) allows the RAM information to be retrievable when the computer is rebooted.

RAM size and Location on the Computer System

Most computers come equipped with 256 million bytes of RAM already on the computer. Additional RAM can be placed within the system. However, there is usually a limitation placed upon just how much RAM can be added to a computer system. RAM is not random as its name would lead one to believe. The RAM is highly controlled and the storage can be directly ascertained. There is a decisive method that RAM utilizes to make its memory available to certain areas of the computer system.

Forms for RAM

RAM is what is known as discrete microchips which means that it is separate. An additional form of RAM is modules which attach into outlets in the motherboard of the computer. A network of electrical pathways to the processor allows the connection to spark for the RAM.

Why is RAM Important

RAM serves the very important function of retrieving information that must be accessed in a quick manner. This operation is very similar to the human brain’s function in retrieving necessary facts from short term memory. Open files and the utilization of applications on a computer systems requires the assistance of RAM. Users that play alot of video games with detailed graphics or keep alot of folders open while on their computer, will need the use of additional RAM. This will allow them to better access the information they need when the time comes. RAM is held onto a limited time, but it allows the information to come up quickly and without much fuss on the part of the computer user.

ROM, RAM and HDD design

ROM, Read only Memory

The data or information stored in these types of memories is not changeable. It therefore does not require electrical power to retain information. The ROM chip or IC contains rows and columns of diodes. The presence or absence of diode in a particular row defines weather it is a binary one or zero. The content of a ROM is permanent and care has to be taken while designing it. It is not possible to rewrite a ROM. If change is necessitated, the whole chip has to be discarded. But once properly designed, they are robust, consume less power and cheap to manufacture.

The different types of ROM are:

1.PROM, Programmable Read only Memory
The design of ROM is made easier by the PROM. PROM contains a fuse at the junction of each row and column of the grid. In the initial stage the complete grid represents a binary one. When an electric charge is passed through it, it ruptures the fuse and becomes a zero.

2.EPROM Erasable Programmable Read only Memory
This is an improvement on PROM. Ultraviolet light is used to erase the information. This is a tedious process and excess exposure may lead to destruction of the ROM.

3.EEPROM, Electrical Erasable Programmable Read only Memory
This kind of ROM is popular in memory sticks. The required portion of the memory can be erased or written on in a selective basis.

RAM, Random Access Memory

This type of memory is essential for the working of a computer. It is a integrated chip consisting of rows and columns of a pair of transistor and a capacitor forming a grid. If the capacitor is charged at 50 % or more, it reflects a binary one. Due to the nature of a capacitor (it discharges at a very fast rate), it is required to charge them periodically. This is called a refresh cycle. In addition to the charging circuitry, it consists of a control circuit which is used to read and write data. Since the data can be accessed and written dynamically, these are called dynamic random access memory. The combined working of all the devices makes it slow in working.

Another type of RAM is the static RAM, where the integrated chip consists of a series of Flip-flops instead of a combination of a transistor and a capacitor. In the absence of a capacitor, there is no need to cater for the refresh cycle and this makes the static RAM considerably faster than a dynamic RAM. A Flip-flop consists of a few transistors and therefore the cost of a static RAM is higher, though it is compact.

Hard Disk Drive (HDD)

A hard disk drive is used to store vast amount of data. The data access time and speed are not critical for this device. The speed of a HDD is specified by the RPM or the rotations per minute of the rotating disc. For an IDE based HDD, the RPM is 5400 or 7200. Faster hard discs with better access time are called SCSI drives which can attain much faster speeds. Since, the HDD works on the principle of rotating disc, its efficiency is restricted by the speed of rotation of mechanical components. Transporting a HDD while in operation may cause a crash and damage the disc.
