The question has the below multiple choices
A) 3DES
B) RSA
C) Blowfish
D) Twofish
The answer is (C)
Blowfish
Also known as the Blow-CAST-Fish
, it was designed to run efficiently on 32 bit computers. Up
to date no significant weaknesses have been seen. Based on Blow-CAST-Fish, it
uses good features of CAST -128[6] algorithms and Blowfish [1]. Features taken
from Blowfish [1] algorithm include; S-box entries which are key dependent
substitution, varying key lengths of up to 448 bits and procedure of Key
expansion
The Software is categorized into two. Operating System Software and the Application software.
Example :
1.0 The monitor does not show pictures without the source, when watching a video the source media application
2.0 The printer does not print on its own without the source data from the office application, print application which process the data.
3.0 The speaker does not produce sound on its own without the source data from the media application as well.
4.0 The central processing units together with the memory does not run without the preinstalled bios and operating software on the computer.
The hardware will not run without the operating software (OS) to connect run each functional part of the computer. The Central Processing Unit computes for the Inputs and Outputs fed to it giving the computer the power to process data coming from all the hardware components receiving the electrical signals translated from the data input from human interaction or other source of data interaction to the computer. To divide we mainly have your hardware components, The Central Processing Unit, The input Peripheral (mouse, keyboard, pen stylus, mics, camera, etc) and your output peripherals (Monitor, Speakers, etc.,). Then we have your software component divided into two. The operating system software (Windows /Mac OS/ Linux / Unix / ) and the application software/program (Office applications, Browser etc.,).
Answer:
C. ground antennas
Explanation:
AKA Satellite Dishes That Communicate Just Like Direct Tv dish It is focused by a bowl-shaped parabolic dish onto a device in the center called a "feed horn", which channels the signal to a "low-noise block down converter" (LNB) which filters out unwanted interference, and sometimes converts it to yet another frequency before amplifying it and sending it to the satellite receiver
