Answer:
Information and communications technology (ICT) is an extensional term for information technology (IT) that stresses the role of unified communications[1] and the integration of telecommunications (telephone lines and wireless signals) and computers, as well as necessary enterprise software, middleware, storage and audiovisual systems, that enable users to access, store, transmit, and manipulate information.
The three most common operating systems for personal computers are Microsoft Windows, Apple Mac OS X, and Linux.
Answer:
Trap is a software interrupt that occurs when there is a system call, while hardware interrupt occurs when a hardware component needs urgent attention.
Explanation:
Interrupt is an input signal that disrupt the activities of a computer system, giving immediate attention to a hardware or software request.
In trap interrupt, the system activities are stop for a routine kernel mode operation, since it has a higher priority than the user mode. At the end of the interrupt, it switches control to the user mode.
The hardware interrupt is a signal from hardware devices like the input/output devices, storage and even peripheral devices that draws an immediate attention of the processor, stopping and saving other activities and executing the event with an interrupt handler.
Answer:
These technologies are: Dual Stack Routers, Tunneling, and NAT Protocol Translation.
Explanation:
Dual Stack Routers - This is the process in which a router’s interface is attached with IPv4 and IPv6 addresses
Tunneling -Tunneling is used as a medium to help the different IP versions communicate with the transit network.
NAT Protocol Translation - This helps the IPv4 and IPv6 networks communicate with each other since they do not understand the IP addresses of each other since, they are different IP versions.
4 because 4 x 4=16. Easy. I like to think of it as multiplication.
