Tablet PC Guide: Important Things to Look for

By on Nov 29, 2011 in Computers, Gadgets |

Apple’s iPad initiated the tablet market before some 18 months, which is now flooded with a variety of choices from HTC, RIM, Samsung, Motorola, and Asus. Undoubtedly, iPad accounted for 80% of the sales initially, which kept the rival tablets at bay. However, this does not mean that the latter tablets are not worth trying. In fact, many people are trying them as well, which has resulted in a floating market of similar tablets at various prices, features, and performance capabilities. So, which is the best tablet to buy? If this is what you need to answer, here’s the tablet PC guide that will reveal the most vital things to look for while buying (do not always focus on Apple’s specifications). Assess Your Network Needs: Is 3G or TV Connection Required? Tablets are available in two versions of which many support both Wi-Fi and 3G connections. You can then choose to connect wirelessly to your home network or can use it with an Internet-enabled SIM card for accessing the Internet while roaming. However, bear in mind that the 3G versions are costly and that they come with data contracts. Nevertheless, you can get them at subsidized rates in many stores. Coming to TV connections, several tablets have the ability to connect to TVs and monitor displays through an HDMI cable. You can choose such a gadget if you want to cast videos on a bigger screen. In this case, prefer a mini-HDMI or full-size output offered by tablets such as Motorola Xoom. However, in case of an iPad, be ready to pay extra. Assess Your OS Needs: Is iOS 5 Required? Although iOS 5 by Apple is the most famous OS for tablets, there are yet many user-friendly and tablet-friendly operating systems to choose from such as Windows 8 and Android 3.0 (Google-backed operating system version). I would suggest the latter ones if you are looking for more flexibility, as iOS 5 is not that open for customization. Assess Your Processor Needs: Is A5 Chip Required? Almost all tablets embed the ARM processor technology that is used in all cell phones. Yes, you even get dual-core ARM processors in many tablets. If you choose iPad 2, it will offer you the A5 chip, whereas the latest Android 3.0 tablets come with Nvidia’s Tegra 2 processor. So again, if customization is your choice, Tegra 2 has to be your choice. Assess Your Storage Needs: 16GB or 32GB? Your storage needs depends on your usage. For example, 16GB is enough for loads of music and photos, while HD video and big applications need much more memory. In case you want an iPad, you must know that it does not offer a memory card slot for expanding the storage capacity, while several other tablets come with built-in microSD/microSDHC slots. Assess Your Screen Size Needs: Small or Big? The most suitable tablet size is the one that makes you work comfortably no matter where you are. If portability is what you prefer, you certainly need a bigger screen. While iPad 2’s screen provides a display of 9.7 inches, Android 3.0 tablets offer 10.1-inch displays. Need a smaller one? Okay, go for 7-inch display offered by Dell Streak 7.

Computer Protection through Internet Security Firewalls

By on Nov 9, 2011 in Antivirus, Computers, Internet |

Computers that do not have firewalls are vulnerable to hackers’ attacks, viruses and spyware. This is why it is mandatory to have a firewall installed on your computer to make sure that your internet connectivity is secured. Using a firewall is considered one of the best ways that will lead to a computer protection. Firewall is defined as security software which is known to operate in such a manner that it can stop unauthorized access, while at the same time allowing other genuine people or software to connect securely to the internet. In case an outside attempt is detected, the software will block and encrypt the attempt that is on its course of happening. This seems to be one of the best means to keep yourself protected against spyware, viruses, malware that tries to connect to network or internet. Regardless if you have installed an antispyware or antivirus system, a firewall is necessary to have on your device. Some of the operating systems, such as Windows Vista and XP come with already installed internet security firewalls, they are actually built-in right from the start. When you operate the system make sure that the firewall is on as it can keep your computer protected from harming elements. There are on the market many antivirus companies that provide firewalls and as such users can disable the firewalls that come with their operating system and install a new, more efficient one. Installing a firewall is mostly recommended if your computer operates on a network. Installing a firewall in each and every computer means that the entire network is protected and will keep malware from attacking every computers on the network. Firewalls are known to exist in two types – software firewalls and hardware firewalls. The first ones block any communication on your computer that is unauthorized. The second one, hardware firewall is installed between computer and router/modem which will not allow any communication that is illicit to happen to your system. Nowadays there is no such thing as a computer that is connected to internet and not requiring a firewall protection. Several renowned antivirus brands such as Symantec, AVG, McAfee are selling firewalls online. But before reaching to these ones, you should check first if your device is equipped with such a security. In case it doesn’t have one, then you should install one as soon as you can if you want to keep your system free from the different malwares that are present on the internet.
