What does “CPU” mean ?

August 26, 2014

Central Processing Unit – (CPU) (formerly also referred to as a central processor unit) is the hardware within a computer that carries out the instructions of a computer program by performing the basic arithmetical, logical, and input/output operations of the system. The term has been in use in the computer industry at least since the early 1960s. The form, design, and implementation of CPUs have changed over the course of their history, but their fundamental operation remains much the same.

A computer can have more than one CPU; this is called multiprocessing. All modern CPUs are microprocessors, meaning contained on a single chip. Some integrated circuits (ICs) can contain multiple CPUs on a single chip; those ICs are called multi-core processors. An IC containing a CPU can also contain peripheral devices, and other components of a computer system; this is called a system on a chip (SoC).

Two typical components of a CPU are the arithmetic logic unit (ALU), which performs arithmetic and logical operations, and the control unit (CU), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.

Not all computational systems rely on a central processing unit. An array processor or vector processor has multiple parallel computing elements, with no one unit considered the “center”. In the distributed computing model, problems are solved by a distributed interconnected set of processors.

What is “HeartBleed” ?

August 19, 2014

Heartbleed – A security bug in the OpenSSL cryptography library. OpenSSL is a widely used implementation of the Transport Layer Security (TLS) protocol. Heartbleed may be exploited whether the party using a vulnerable OpenSSL instance for TLS is a server or a client.

Heartbleed results from improper input validation (due to a missing bounds check) in the implementation of the TLS heartbeat extension, the heartbeat being the basis for the bug’s name. The vulnerability is classified as a buffer over-read, a situation where software allows more data to be read than should be allowed.

A fixed version of OpenSSL was released on April 7, 2014, on the same day Heartbleed was publicly disclosed. At that time, some 17 percent (around half a million) of the Internet’s secure web servers certified by trusted authorities were believed to be vulnerable to the attack, allowing theft of the servers’ private keys and users’ session cookies and passwords. The Electronic Frontier Foundation, Ars Technica, and Bruce Schneier all deemed the Heartbleed bug “catastrophic”. Forbes cybersecurity columnist Joseph Steinberg wrote, “Some might argue that [Heartbleed] is the worst vulnerability found (at least in terms of its potential impact) since commercial traffic began to flow on the Internet.”

AVG Internet Security 2014 (2014.0.4744) – Paidware Review

August 14, 2014

The Rating Scale Breakdown:

  • 0  – 0.5 – Abysmal
  • 1.0 – 1.5 – Terrible
  • 2.0 – 2.5 – Poor
  • 3.0 – 3.5 – Average
  • 4.0 – 4.5 – Great
  • 5.0 – Excellent
  • Undetermined – Too soon to tell or lacking evidence to provide a solid answer
  • Not Tested – Has yet to be requested or there is some limitations to prevent accurate test results

————————–

Price$54.99 CAD/USD – For 1 year and 1 PC

A. Installation AVG4.5 Great” – There is no doubt that AVG has improved in this area 10 fold. I personally thank G-d that this time around it did not take more then once to install AVG Anti-Virus 2014. As oppose to AVG Anti-Virus 2013 that took more then a dozen times to install it on my PC’s. So well done AVG for getting it right this time. Better late then never.

B. Un-installing AVG3.5Average” – AVG Free Anti-Virus 2014 is very sloppy un-installer. But that is not a surprise to me. So has every other previous AVG version going back 5 or 6 years.

————————–

C. Stability Of Program5.0 Excellent – The UI (User Interface) seems to have been completely fixed in AVG 2014. Along with the jenkey manual update option.

————————–

D. Has AVG Free Been Compromised By Hackers Or Virus4.0Great” – No reports of AVG being compromised.

E. Speed of Scan5.0 Excellent – Very quick on most computers.

F. Updating - 4.0Great” – Automatic updating is fine. But if you want to manually update your AVG. Expect some epic slowness. I’m still not sure why. I have often run into times where it will stall on 30%, or 50% and it seem like forever before you get the 100% completed notice.

G. Does AVG Free Do Automatic Updates By Itself Without Any Issue – 5.0 – Yes, you can now with, no doubt. But leave the manual update option alone unless you want to invite stability related issues.

H. Internet Browser Cookie Detection Rate And Removal Test2.0 Poor- You are way better off with something like SUPERAntiSpyware or CCleaner that is more dedicated to removal of Internet cookies. AVG Internet cookie detection rate is terrible even with the option active and checked off.

————————–

1. Anti-Virus Detection Rate Test:

1A. Windows XP – 4.0Great

1B. Windows Vista – 4.0Great

1C. Windows 74.0Great

1D. Windows 84.0Great

————————–

2. Residential Shield Test - 3.5Average – I still find AVAST and AVIRA seems to grab the virus way before AVG does.

————————–

Computers Protection

————————–

3A. Anti-Virus Scanner 4.0Great” – AVG has finally beaten their just average score. And that should tell you a lot.

3B. Anti-Rootkit Scanner4.0Great” – Great option. Works well.

————————–

Web Browsing Protection

————————–

4A. Link Scanner4.5Great – Not a fan. But it can be very useful to some.

4B. Online Shield2.5Poor” – Completely in-effective and worthless.

————————–

Identity Protection

————————–

5A. Identity Protection - 2.0Poor” – Completely in-effective and worthless.

5B. Identity Alert – This feature appears to need a further upgrade. Beyond your main purchase of AVG Internet Security 2014.

————————–

E-mail Protection

————————–

6A. E-mail Scanner3.0Average” – Utterly baseline and average. I found no use for it.

6B. Anti-Spam3.0 Average” – Utterly baseline and average. Not even worth the setup.

————————–

Firewall

————————–

7. Firewall5.0 Excellent – By no means perfect. But way better then your standalone Windows built in Firewall

————————–

Extra Features

————————–

8. PC Analyzer (AKA. Fix Performance) – 0.5Abysmal“- If you don’t mind that you only can fix your errors for free once then great. But if you are like me and you probably feel this options is both somewhat misleading and out right bait to buy this extremely expensive add-on. Then you are probably with me on my conclusion.

9. Mobile ProtectionN/A – This option is pretty much just a bullet point reminder. As you can download the AVG Free Smart Phone or Tablet app from the Google Play Store. Again let me make it clear even thou you have paid for AVG Internet Security 2013. You don’t get AVG Pro Smart Phone app.

10. File Shredder3.5 Average – I found this addition to be very useful. But lacking what Spybot – Search & Destroy or even Advance System Care 6. Advanced File shredder options.

11. Tech Buddy Support0.0Abysmal” – This is just a cash grab. Completely worthless as well as falsely advertised and overally misleading to the end user.

12. AVG Direct Support0.5Abysmal” – With only a free forum and a phone number to call for support.

You will often find yourself ether being told to go to the free forum or they will recommend you go to further specialized support team via Tech Buddy. Which like I said above is an epic MONEY GRAB. Completely worthless as well as falsely advertised as well as overally misleading.

————————–

My Overall Score: 85/125

68.4 % = C +

————————–

My Final Verdict - AVG Internet Security 2013 takes what it once was and flips it on its heads. Then presents itself as a new more user friendly version of its past iterations. “Well sorry guys, That won’t fly with me.” But you got to love the File Shredder even thou it is so very basic.

This version of AVG and I’m talking about all AVG 2013 versions. Are clearly tailored first to Windows 8 and then to Windows 7. If you don’t have ether. Then you maybe as disappointed as I was. When I first upgraded from AVG Internet Security 2012.

What does “XML” mean ?

August 12, 2014

XML - (Extensible Markup Language) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. It is defined in the XML 1.0 Specification produced by the W3C, and several other related specifications, all free open standards.

The design goals of XML emphasize simplicity, generality, and usability over the Internet. It is a textual data format with strong support via Unicode for the languages of the world. Although the design of XML focuses on documents, it is widely used for the representation of arbitrary data structures, for example in web services.

Many application programming interfaces (APIs) have been developed to aid software developers with processing XML data, and several schema systems exist to aid in the definition of XML-based languages.

What does “PHP” mean ?

August 5, 2014

PHP – A server-side scripting language designed for web development but also used as a general-purpose programming language. As of January 2013, PHP was installed on more than 240 million websites (39% of those sampled) and 2.1 million web servers. Originally created by Rasmus Lerdorf in 1994, the reference implementation of PHP is now produced by The PHP Group. While PHP originally stood for Personal Home Page, it now stands for PHP: Hypertext Preprocessor, a recursive backronym.

PHP code can be simply mixed with HTML code, or it can be used in combination with various templating engines and web frameworks. PHP code is usually processed by a PHP interpreter, which is usually implemented as a web server’s native module or a Common Gateway Interface (CGI) executable. After the PHP code is interpreted and executed, the web server sends resulting output to its client, usually in form of a part of the generated web page – for example, PHP code can generate a web page’s HTML code, an image, or some other data. PHP has also evolved to include a command-line interface (CLI) capability and can be used in standalone graphical applications.

PHP is free software released under the PHP License. PHP has been widely ported and can be deployed on most web servers on almost every operating system and platform, free of charge.

What does “GBP” mean ?

July 29, 2014

GBP - The pound sterling (symbol: £; ISO code: GBP), commonly known simply as the pound, is the official currency of the United Kingdom, Jersey, Guernsey, the Isle of Man, South Georgia and the South Sandwich Islands, the British Antarctic Territory and Tristan da Cunha. It is subdivided into 100 pence (singular: penny). A number of nations that do not use sterling also have currencies called the pound. At various times, the pound sterling was commodity money or bank notes backed by silver or gold, but it is currently fiat money, backed only by the economy in the areas where it is accepted.

The British Crown dependencies of Guernsey and Jersey produce their own local issues of sterling: “Guernsey pound” and “Jersey pound”. The pound sterling is also used in the Isle of Man (alongside the Manx pound), Gibraltar (alongside the Gibraltar pound), the Falkland Islands (alongside the Falkland Islands pound), and Saint Helena and Ascension Island in Saint Helena, Ascension and Tristan da Cunha (alongside the Saint Helena pound). Manx, Gibraltar, Falkland Islands and Saint Helena pounds are separate currencies, pegged at parity to the pound sterling.[citation needed] The Bank of England is the central bank for the pound sterling, issuing its own coins and banknotes, and regulating issuance of banknotes by private banks in Scotland and Northern Ireland. Banknotes issued by other jurisdictions are not regulated by the Bank of England; local governments use Bank of England notes as backing for local issuance by allowing them to be exchanged 1:1 at face value.

Sterling is the fourth most traded currency in the foreign exchange market, after the United States dollar, the euro, and the Japanese yen. Together with those three currencies it forms the basket of currencies which calculate the value of IMF special drawing rights, with an 11.3% weighting as of 2011[update] (USD 41.9%, Euro 37.4%, Yen 9.4%). Sterling is also the third most held reserve currency in global reserves (about 4%).
