Kenneth created a system that stores numbers using floating‑point representation, it has eight bits for the mantissa and four bits for the exponent.Kenneth decided to increase the number of bits used to 16, this means that:
Precision of numbers represented will increase, range of numbers represented will decrease
Range of numbers represented will decrease, precision of numbers represented will decrease
Precision of numbers represented will decrease, range of numbers represented will increase
Precision of numbers represented will increase, range of numbers represented will increase
What is circuit switching?

In Asymmetrical encryption, which key is sent by whom?
The public key from the sender to receiver
the public key from receiver to sender
the private key from receiver to sender
the private key from sender to receiver
The light are 1st polarized at random leaving 4 possible outcomes, then the receiver use 2 beams splitter randomly to read the data to generate a string of 0 and 1, the string created is sent back to review, now how can both computers synchronize?
The sender readjust the polarizer in accordance with the data of the receiver to match each other.
The sender generate another set of light to fit better with the data received so transmission is similar.
The sender switch transmitting line corresponding with the data so received to ensure secureness.
The sender check for the errors in the reading of data so the receiver can readjust the splitters.
Describe 1 advantage for cisc and risc and application
risc: short instruction.use in phones cisc: need less storage. use in laptops
RISC: simple short instructions used, lower process time. use in phonesCISC: complex instructions which reduces memory storage .commonly used in automation devices/laptops
risc: short instructioncisc.less storage
risc: long instructioncisc: more storage
)state and briefly explain a reason why pipelining can be implement easier with risc:
risc has simpler instructions hence execute in 1 cycle
simple 1 phase instructions
1 cycle easy to do
1 cycle instructions risc, cisc variable length makes it hard to implement
