What is the concept of 40800 Kbps, 5000 K bytes seconds? I don t understand, help me convert

The information in the computer is represented by binary 0s and 1s, where each 0 or 1 is called a bit, which is represented by a lowercase b, that is, a bit; Uppercase b means byte, that is, byte, one byte eight bits, that is, 1b 8b; The preceding capital k means thousand, i.e. thousands of bits (kb) or thousand bytes (kb). Indicates the size of a file, and generally uses bytes (KB) to represent the size of the file.

kbps: The first thing to understand is that PS stands for S, which is per second. kbps refers to the network speed, that is, how many kilobytes of information are transmitted per second (k represents thousands, kb represents how many thousand bits), in order to intuitively appear that the transmission speed of the network is faster, general companies use kb (thousands) to represent, if it is kbps, it means how many kilobytes are transmitted per second.

The speed of 1kbps is 512kbps, and if converted to bytes, it is 512 8 64kbps (i.e. 64 kilobytes per second).

Causes of slow internet speed and ways to improve internet speed:1If your computer is infected with certain viruses or Trojans, it will cause your internet connection to be slow.

First, use anti-virus software to check the virus comprehensively; Then check the CPU operation and network conditions, if the CPU keeps running for no reason, and the network connection is not broken, it may be caused by a virus Trojan. 2.A computer has to go through many servers to reach its destination, so the server directly affects the speed of the computer's network.

3.If your system is used for a long time, there will often be problems, such as a sudden slowdown in the network speed after a long time of booting, you can restart it to see if it can solve the problem. Being busy with work can directly affect the speed of your network and computer.

To keep it good for heat dissipation. 5. The influence of worms causes the network speed to slow down. Worms distributed via e-mail have an increasingly serious impact on network speed and are extremely harmful.

This virus causes the infected user to send e-mails as soon as they go online, and the virus selects random documents from the user's personal computer to attach them to a random address in the user's address book to send e-mails. Hundreds or thousands of such spam emails are sent out in queues, or they are returned in batches and piled up on servers. As a result, some backbone Internet networks are obviously congested, and the network speed is significantly slowed down, so that the local area network is nearly paralyzed.

Therefore, it is necessary to upgrade the antivirus software used in a timely manner; The computer system should also be upgraded in a timely manner, install system patches, uninstall unnecessary services, and close unnecessary ports to improve the security and stability of the system. 6. Don't install too much. Firewall.

Excessive use of firewalls can also lead to slow down network speeds, so uninstall unnecessary firewalls and keep only one powerful one. 7.The system resources are insufficient.

There may be too many applications loaded and running in the background, so it is necessary to load the software reasonably or delete the useless programs and file cores to achieve the effect of improving the network speed. It's a good idea to kill the virus before shutting it down, because the virus is active all the time, and once infected, it will greatly affect the speed of the Internet. 8.

Use good antivirus software to change nonsense. Antivirus software should be upgraded every day, don't be afraid of trouble. 9.

**An internet speed monitoring and control software, such as P2P network terminator, Jusheng network management and cyber enforcement officer, etc., can detect whether your bandwidth is throttled or stolen by others, and you can also set the internet speed.
