write the name of any four devices of local and modern technology
Answers
Answer:
1.An Internet Modem
The word “modem” is actually a misnomer, as it’s a carryover from the days of when a digital signal needed to be modulated to be sent over an analog phone line and then demodulated on the receiving end.
2. A Router
The router is a small but important piece of office equipment that sits between an internet modem and the office network. Sometimes an internet modem can double as a router. However, a standalone router provides a number of benefits.
3. A Network Switch
Routers typically have a limited number of physical ports. Fortunately, a router can be connected to a switch. Switches have as many as 48 ports. Switches can also be stacked. If you have, say 24 VoIP phones in your office, each one will need a port (although a VoIP phone and a computer can be daisy chained to a single switch port).

4. An Uninterruptable Power Supply (UPS)
UPS manufacturers such as CyberPower offer a wide range of devices, ranging in price from a few hundred dollars to many thousands of dollars.
Since modems, routers and switches are low power devices, a low-end UPS can keep these running for a few hours during a power failure. Employees using charged up laptops can continue to work for a time.
More expensive UPS devices can keep servers and network-powered VoIP phones running for hours.
