Answer:
A little down arrow is used in word to sort the text and perform different type of function like convert text, Date, Numbers in to ascending or descending order such as A to Z or Z to A. it is used to convert paragraphs, heading, statement convert into ascending or descending.
Answer: The columns in a table are the set of facts that we keep track of about that type of object.
Explanation:
Answer:
Transport layer
Explanation:
The transport layer is responsible for maintaining end to end communication between devices connected on a network.
The TCP/IP determines how data is exchanged between devices connected on a network by providing end to end communications that determines how it should be broken into packets.
Answer:
It is A: Packet metadata is used to route and reassemble information travelling through the internet.
Explanation:
Step 1: The Internet works by chopping data into chunks called packets. Each packet then moves through the network in a series of hops. Each packet hops to a local Internet service provider (ISP), a company that offers access to the network -- usually for a fee
Step 2: Entering the network
Each packet hops to a local Internet service provider (ISP), a company that offers access to the network -- usually for a fee.
Step 3: Taking flight
The next hop delivers the packet to a long-haul provider, one of the airlines of cyberspace that quickly carrying data across the world.
Step 4: BGP
These providers use the Border Gateway Protocol to find a route across the many individual networks that together form the Internet.
Step 5: Finding a route
This journey often takes several more hops, which are plotted out one by one as the data packet moves across the Internet.
Step 6: Bad information
For the system to work properly, the BGP information shared among routers cannot contain lies or errors that might cause a packet to go off track – or get lost altogether.
Last step: Arrival
The final hop takes a packet to the recipient, which reassembles all of the packets into a coherent message. A separate message goes back through the network confirming successful delivery.

The X's have been correctly placed in the chart
A surge suppressor, which is also commonly known as a surge protector, is an important equipment that helps prevent damage to electric components from an unexpected increase of voltage. Let’s assume that you are living in a county where the effective utility voltage is between 110 to 120 volts. Assume that the accepted peak voltage should not be anything higher than 170 volts. If there is a surge and this surge reaches peak levels of 170 volts and higher, surge suppressors should jump in and prevent the peak AC voltage from going above the threshold.
People tend to confuse line conditioners and surge suppressors. While surge suppressors protect components from surges, line conditioners are built to make up for the loss of voltage from the lines. It does so by storing some power energy. This stored energy can later be modified and used when the volts drops to the desired 110 volts.
A UPS has DC battery power that provides battery backup power when the electricity goes off or when the levels of voltage drop significantly. When the electricity goes off means that the voltage is at 0 volts and it is the work of the UPS to kick its backup power in.
