pre convert single digits, or sometimes parts of a sum, then sum up. like this:
1.) 2³+2²+2^1+2^0 = 8+4+0+1 = 13
2.) 512 + 0 + 128 + 0 + 0 + 16 + 0 + 4 + 2 + 0 = 1010010110
you just need to know what the powers of two are, then you know how to convert numbers.
like 100 = 4 and 1 = 1 then 101 = 4 + 1 and in the other direction just take chunks of 5 until theres nothing left, but care not to overshoot the sum
5 = 2² + 0 + 2^1 = 101 in base2
the zeros are for the order, every time I would overshoot, it's a zero.
3.) 16 + 2 + 19 = 37
4.) 8² is 64, or (100)base8
8³ or 1000 would already overshoot, so let's see what we can do with the smaller value of a digit in base8, 8² = 64
we can 8 different digits (0 to 7) in base8
7x8^2 + 2*8^1 + 5*8^0
448 + 16 + 5
= (725)base8

edit1: recharging my phone now. but I need to show quickly in order to get my own stuff done.
quick side note on topic: the number always stays the same, like if there would be a number of beans lying on the table. we justcrrorder them to write in another system. in normal base 10, 312 beans would be grouped intuitively in 3*100, 1*10 and 1*1
or: 3*10^2 + 1*10^1 + 2*10^0
note that something to the power of zero is always one (e.g.: 5^0 is like 5÷5)

the second generation computer used. as a memory device
Answers
Answer:
The period from 1959-1965 was the second generation. Transistors that are cheaper, consumed less power, were used in this generation, were more compact, were more reliable, and were faster than first-generation vacuum tubing machines.
Explanation:
The primary memories and the magnet tapes and magnetic discs were used as secondary storage equipment in this generation.
The montage language and high programming languages such as FORTRAN, COBOL, have been used in this generation. The computers used batch processing and operating system multi-programming.
A memory is like the brain of human beings. It is used for storing information and instructions. Computer memory is the storage space on the computer that processes data and saves instructions for processing.
The memory is split into many small parts known as cells. There is a unique address for each location or cell, which varies from 0 to memory minus one.
There are three basic types of memory:
Memory Cache
Main Memory/Primary Memory

Group of answer choices.

B) the private key had been compromised.
C) the symmetric encryption key had been compromised.
D) the asymmetric encryption key had been compromised.
Answer:
C) the symmetric encryption key had been compromised.
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
In Cyber security, encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext.
Typically, an information or data that has been encrypted can only be accessed and deciphered by an authorized user.
Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.
Email encryption is the encryption and authentication of an email to protect the message therein from being read by any person other than the intended recipients. Thus, it protects the email from hacking or invasion by a third party.
Basically, when the message is signed with the sender's private key, the receiver can verify its authenticity using the sender's public key.
Also, encrypting the email message with the receiver's public key provides confidentiality.
In this scenario, the most likely explanation for this result is that the symmetric encryption key had been compromised.

Hope it helps.... :) Computers work on the garbage-in, garbage-out concept. Comment
Answers
Because computers operate using strict logic, invalid input may produce unrecognizable output, or "garbage." For example, if a program asks for an integer and you enter a string, you may get an unexpected result. Similarly, if you try to open a binary file in a text editor, it may display unreadable content.
GIGO is a universal computer science concept, but it only applies to programs that process invalid data. Good programming practice dictates that functions should check for valid input before processing it. A well-written program will avoid producing garbage by not accepting it in the first place. Requiring valid input also helps programs avoid errors that can cause crashes and other erratic behavior.
NOTE: Because the related terms FIFO and LIFO are pronounced with a long "i," GIGO is typically pronounced "guy-go" (not gih-go). This also helps avoid confusion with the prefix "giga," which is pronounced with a soft "i."

Answers
Answer:
Go into short-term memory
Explanation:
Data stored on physical storage devices must go into short-term memory before the processor can access it.
This is because, physical storage devices are secondary memory which store information for a long time. The CPU does not work directly with secondary memory but with primary or short term memory. Since the CPU works mainly with short term memory, information in physical storage or secondary memory has to go into short term memory for the CPU to be able to process it.
So, data stored on physical storage devices must go into short-term memory before the processor can access it.
