Answer:
False.
Explanation:
In the C-SCAN disk scheduling algorithm, the disk arm is required to move in one direction only until it reaches the last track or there are no more requests to service in that direction, then it reverses direction and the scan proceeds in the opposite direction in the same fashion is a False statement.
Answer: Computer viruses
Explanation:
Computer viruses are programs that need to be attached to other files to install themselves on computers without the users’ knowledge or permission and spread—sometimes very rapidly. A spyware is also a program that installs itself on a computer without the user's knowledge and tries to collect sensitive information such as passwords, credit card details and sends this information to a remote computer. A computer worm is a type of a virus that replicates itself across different computers. Freeware on the other hand is software that can be obtained for free.
Because it combines a computers into pretty much one computer
Answer:
The three important concepts in the Federal Networking Council's definition of the Internet are, namely;
- Packet switching
- The TCP/IP communications protocol
- Client/server computing
Explanation:
- Packet switching involves the transfer of data which are grouped into different packets and then sent over a digital network to their respective destination. After the data are received at the destination site, they are then extracted and used by the application software.
- The transmission control protocol/internet protocol allows one computer to connect or communicate with another one through the internet. The internet protocol defines how to route and address each packet to ensure it gets to the right destination. The IP address of a particular device on a network is usually unique to that device.
- Client/server computing describes how a server provides services by taking requests from clients computers and sharing its resources with one or more computers.
Science and mathematics. STEM can also be engineering but in John’s case, he’s a METEOROLOGIST WHO DOES THE WEATHER FORECAST and meteorologists is part of a study in science and also mathematics because of measuring the speed of some related computations
