Answer:
b. they are located at the intersections of the network of wires and cables that make up the internet.
Explanation:
Given that Router is a computer networking device that operates by transferring data packets between computer networks, while also ensuring traffic organizing tasks on the Internet.
Hence, Routers put packets in the right order after they arrive at their destination by matching the destination IP address of the packet and one of the addresses in the routing table.
Also, Routers check the address on each packet that arrives and decide which way it should go next by ensuring the data packets are summarized for the outgoing interface recorded in the table entry.
Therefore, the correct answer is option B
Answer:
To make a computer more secure
Explanation:
we have following ways :
1)we should have anti virus to protect our computer.
2)we should not play or look computer for a long time because it destroy our files
Answer: This 16-bit field defines the entire packet size in bytes, including header and data. The minimum size is 20 bytes (header without data) and the maximum is 65,535 bytes. All hosts are required to be able to reassemble datagrams of size up to 576 bytes, but most modern hosts handle much larger packets.
Explanation: Hopefully this helps you with what ever u are doing.

- Computer mouse
- Finger on touch screen.
- Joystick.
- Leap Motion.
- Light pen (pen)
1.Mouse
Mouse is most common type of input device that is used for pointing the data on the screen. We press it with our hands and keep pointing the things.
There are three types of mouse
- optical mouse
- wireless mouse
- trackball mouse.
2. Finger on touch screen
In this type of movement the fingers are input devices those we use to see the movement of pointer on the screen and this is most common in this century.
3.Joystick.
Joystick is another input device to point the cursor but it is mostly used in games. Children can use it smartly so it is inculcated in games usually.
4. Leap Motion
The Leap Motion (LM) controller is a latest 3D sensing device for hand posture interaction with a computer. It is having the capability sense the location of the fingers of the hands, as well as the palm position.
5.Light Pen
this is another pointing device which is mostly used to highlight and select the data on the screen.
Note: All of these above pointing devices are most common used now a days. These devices are having new conventions day by day for the ease of user. This era is basically the era of IT ,so the use of computer must be so easy and conventional for the user so, the innovations and improvement in such devices is made side by side.
