Share: Domain Name

A domain name is a website URL, is the address, is your website name where Internet users can find and visit your website. Computers use IP addresses, which are a series of number. However, it is difficult for people to remember. Because of this, domain names were developed and used to identify entities on the Internet rather than using IP addresses.
 
A domain name can be any combination of letters and numbers, and it can be used in combination of the various extensions, such as .com, .net and more.
 
The domain name must be registered before you can use it. Every domain name is unique. If someone types in www.yourdomain.com, it will and only go to your website.
 
Domain names are formed by the rules and procedures of the Domain Name System (DNS). Any name registered in the DNS is a domain name.
 
"Domain names are organized in subordinate levels (subdomains) of the DNS root domain, which is nameless. The first-level set of domain names are the top-level domains (TLDs), including the generic top-level domains (gTLDs), such as the prominent domains: com, info, net, edu, and org, and the country code top-level domains (ccTLDs). Below these top-level domains in the DNS hierarchy are the second-level and third-level domain names that are typically open for reservation by end-users." - Wiki
 
The top-level domains (TLDs) such as com, net and org are the highest level. Top-level domains form the DNS root zone of the hierarchical Domain Name System. Every domain name ends with a top-level domain label. 
 
Below the top-level domains in the domain name hierarchy are the second-level domain (SLD) names. These are the names directly to the left of .com, .net, and the other top-level domains. As an example, in the domain sample.co.us, co is the second-level domain.
 
Next are third-level domains, which are written immediately to the left of a second-level domain. There can be fourth- and fifth-level domains, and so on, with virtually no limitation. Each label is separated by a full stop (dot).

Share: Money Game

Money game schemes, also known as 'Skim Cepat Kaya', are schemes dressed up as an investment-platform. They look legitimate but in fact they are illegal. Often, they falsely promise much higher interest rates, returns or profits to attract potential victims. They have no intention to uphold their promises. They seek to lure new victims. They use the new depositors' money to repay the earlier depositors. Eventually, these money game schemes will collapse and the depositors will lose their investments and money. Members of these money game schemes will approach the victims at various locations. They normally come with luxury cars to convince the victims. During sharing, they will emphasize someone to be successful after joining the investment scheme. Remember: * Only deposit and invest with parties licensed by the authorities. * When in doubt, check with Bank Negara Malaysia, the Securities Commission or other relevant authorities about a company before making any decision.

Share: DDoS

Distributed denial of service (DDoS), happens when attackers send requests to a target’s IP address, causing the server or network to become overwhelmed, resulting in a denial-of-service to normal traffic. Symptoms of a DDoS attack: - a site or service is suddenly very slow or unavailable - suspicious amounts of traffic from a single IP or IP range - suspicious amounts of traffic from users who share the same profile, device, etc - odd traffic patterns, spikes at odd hours, etc Some methods to reduce or even to prevent DDoS: - monitor web traffic - restriction (for example country) - use cloud - increase bandwidth - have plans (for example security plans)

Share: A.I. Chat

Artificial Intelligence (AI) chat, often referred to as A.I. chat or chatbots, represents a revolutionary approach to human-computer interaction. It involves the use of advanced algorithms and machine learning techniques to enable computers to engage in natural language conversations with users. A.I. chat systems have become increasingly prevalent in various applications, ranging from customer support and virtual assistants to educational tools and entertainment platforms. Evolution of A.I. Chat: The roots of A.I. chat can be traced back to early attempts at creating conversational agents, such as ELIZA in the 1960s. These early systems relied on rule-based approaches and predefined scripts to simulate conversations. Over the years, advancements in natural language processing (NLP) and machine learning have transformed A.I. chat into more sophisticated and context-aware systems. Key Components of A.I. Chat: * Natural Language Processing (NLP): NLP is a critical component ...
