I'd question the wording, However:
Monitor, Output device.
Keyboard, Input device.
Mouse, Input device.
Speakers Output Device.
Microphone, Input device.
Printer, Output device.
Scanner, input device.
Devices do not have to explicitly be one or the other e.g. a printer with a scanner, or headphones with a microphone.
Answer:
D. Electronic Funds Transfer (EFT)
Explanation:
e-commerce is a short for electronic commerce and it can be defined as a marketing strategy that deals with meeting the needs of consumers, by selling products or services to the consumers over the internet.
This ultimately implies that, e-commerce is strictly based on the buying and selling of goods or services electronically, over the internet or through a digital platform. Also, the payment for such goods or services are typically done over the internet such as online payment services.
A payment gateway can be defined as a merchant service technology used for the capturing, acceptance and transfer of digital payment from the bank account of a customer (buyer) to the bank account of the merchant (seller). Thus, payment gateway typically involves the use of credit or debit card for the payment of goods purchased or services provided.
In this scenario, you need to pay an Internet Service Provider (ISP) for services rendered. Thus, the payment technology which you would use is Electronic Funds Transfer (EFT).
Answer:
C. Yes, public key encryption is built upon computationally hard problems that even powerful computers cannot easily solve
Explanation:
Public Key encryption makes use of a public key and a private key to secure data sent over the internet, such as credit card information. The public key is shared publicly, as seen with an SSL/TLS certificate. The data encrypted by the public key can only be decrypted by the private key found on the website server. Data encrypted by the private key can only be decrypted by a specific public key. This makes public key encryption complex and hard to solve, making it very secure .
I would say it is a short term effect because things like wheat grow back, and the other ingredients are generally also able to be replenished. You wouldn’t be taking resources that are nonrenewable.
