Answer:
D. 2.6 GHz processor, 8 GB RAM, 1 TB hard drive
Explanation:
In Computer science, the processor speed of a computer can be defined as the number of cycles per seconds that the central processing unit (CPU) of a computer operates. The processor speed typically determines the number of information that a computer is able to execute per seconds. Therefore, the higher or faster the processor speed the faster the computer in processing complex data.
Generally, the processor speed of a computer is measured in megahertz (MHz) or gigahertz (GHz).
Additionally, Radom Access Memory (RAM) can be defined as the main memory of a computer system which allow users to store commands and data temporarily. RAM is measured in megabytes (MB) or gigabytes (GB).
Generally, the Radom Access Memory (RAM) is a volatile memory and as such can only retain data temporarily.
All software applications temporarily stores and retrieves data from a Radom Access Memory (RAM) in computer, this is to ensure that informations are quickly accessible, therefore it supports read and write of files.
Hence, the computer which is the fastest to process complex data is the 2.6 GHz processor, 8 GB RAM, 1 TB hard drive because of the higher processor speed and RAM size.
Answer:
b. ethernet
Explanation:
It was an ethernet that was developed in the 1970s that improved the ability to send the information over the network. It is the most widely used method to connect the computers in a LAN or the local area network, ever since 1980 when it was first introduced for commercial use. And it is being used in bulk even today.
