An API integration (Application Programming Interface) is the connection between two or more applications, via their APIs, that lets those systems exchange data. API integrations power processes throughout many high-performing businesses that keep data in sync, enhance productivity, and drive revenue. 

1. Private keys should only be used in parts of your software that are inaccessible to outside parties like your customers. These keys allow for processing transactions and querying on account data, so make sure these are kept secret.

2. Public Keys are designed to be used in places where a customer might be able to see them. For example, using these keys in the HTML on your website is the expected use case for these keys.

API: * Used with Payment API, Payment Device SDK for Windows/Linux, Payment Device SDK for iOS/Android, Customer-Present Cloud, Direct Connect SDK, Three Step Redirect, and Query APIs. 

Digital marketing is the practice of promoting products or services with the help of digital devices and technology.

This form of marketing uses the internet and digital technologies to target/connect specific audiences through segmentation. It includes various practices such as search engine optimization (SEO), search engine marketing (SEM), social media marketing (SMM), content marketing, email marketing, pay-per-click advertising (PPC), and social media marketing. 

Payment gateways are technology platforms that enable merchants to accept, process, and manage various payment methods. They are interfaces that collect consumer payment information and act as intermediaries in electronic financial transactions. 

Payment gateways can be used for online and in-store payments, and they typically connect to a web server point of sale (POS) terminal. 

Here are some benefits of using payment gateways:

1. Security and Fraud Prevention:

• Payment gateways employ encryption and tokenization to protect sensitive customer data during transactions.
• They help prevent fraudulent activities by verifying card details and monitoring suspicious behavior.

2. Global Reach:

• Payment gateways allow businesses to accept payments from customers worldwide, supporting various currencies and payment methods.
• This expands market reach and facilitates international sales.

3. Convenience and Speed:

• Customers can make payments online or in-store seamlessly, enhancing the overall shopping experience.
• Transactions are processed swiftly, reducing checkout time.

4. Integration with E-Commerce Platforms:

• Payment gateways integrate seamlessly with popular e-commerce platforms (e.g., Shopify, WooCommerce, Magento), streamlining payment processing for online businesses.

5. Automated Processes:

• They automate payment reconciliation, invoicing, and reporting, saving time and reducing manual errors.
• Recurring payments and subscription billing are also managed efficiently.

6. Flexible Payment Options:

• Payment gateways support various payment methods: credit/debit cards, digital wallets, bank transfers, and more.
• Customers can choose their preferred way to pay.

7. Improved Cash Flow:

• Real-time processing ensures timely fund transfers to merchants’ accounts.
• Businesses can manage cash flow effectively.

8. PCI Compliance:

• Payment gateways adhere to Payment Card Industry Data Security Standard (PCI DSS) requirements, ensuring data protection and compliance. 
• PCI DSS v4.0 has 51 requirements specifications that come into effect on March 31, 2025.  NOTE:  PCI DSS v3.2.1 will remain active until March 31, 2024, giving organizations until then to learn and implement the new standards. 

9. Customer Trust and Reputation:

• Offering secure payment options builds trust with customers.
• A reliable payment gateway enhances a business’s reputation.

10. Analytics and Insights:

• Payment gateways provide transaction data, helping businesses analyze sales patterns, customer behavior, and revenue trends.

SAS stands for Statistical Analysis System, and it is written in C language.

Statistical software mainly used for data management, analytics and business intelligence is called as SAS.  SAS is used in most of the operating systems. SAS can be used as a programming language and also as graphical interface. It can read data from spreadsheets and databases. The output can be given as tables, graphs and documents.  SAS is used to report, retrieve and analyze statistical data and it is also used to run SQL queries. 

An SDK – otherwise known as a software development kit or devkit – is a collection of software programs for the purpose of creating applications across web and/or mobile platforms for a particular operating system.

The SDK will typically contain a wide range of tools, libraries, documentation, code samples, processes, and guides that allow developers to build an app for a platform.

For example: both the Android and iOS platforms have separate SDKs that serve as a foundation for mobile app developers.

Cat5e cable is the minimum standard used for LAN drops. It has a bandwidth of 100 MHz. It is used in 100Base-T Ethernet. Its maximum data rate is 1 Gbps at up to 100 meters, when introduced it was a large upgrade over the 100 Mbps rate of Cat5.

Cat6 Rating requires more stringent specs for cross talk and system noise than Cat5e, Cat6 cable is able to support gigabit Ethernet. It is also used for phone lines and in residences. It has a bandwidth of 250 MHz, and its data rate is 1 Gbps at up to 100 meters and 10 Gbps at up to 37 meters.

Cat6a is routinely used for gigabit Ethernet in data centers and commercial buildings. Its 500 MHz bandwidth is double that of Cat6 and its data rate is 10 Gbps up to 100 meters. Cat6a is commonly shielded twisted pair cabling, which makes the cable heavier, more difficult to bend and up to 30% more expensive.

Cat7 cable has the same data rate and distance specifications of Cat6a (10 Gbps up to 100 meters) however it offers 100 MHz more bandwidth and costs about 20% more. It is used for 10 Gbps critical infrastructure and is largely found in data centers. Its performance is similar to Cat6a but it has more shielding.

Cat8 was designed only for data centers where distances between switches and servers are short. You can use cat 8 cables in standard office applications, however that is not what they were designed for. It is not intended for general office cabling. Cat 8  supports up to 2000 MHz, 25Gbps but only for distances up to 30 Meters. It is typically thicker shielding than Cat 7
