In your own words, explain the difference between the client and server in a classic relationship.
I client computer requests a certain task from the server computer. The server obliges and not only performs the task but manages/organizes its contents. In this classic relationship the client receives and the server gives. Clients rely on servers to provide them with what they need. It's as if clients are a dependent variable and servers are the independent variable. They each have their own role/job they are responsible for and stay within that role, aka their roles are absolutely NOT interchangeable in a classic relationship.
Convert the binary number 01100110 to decimal. Show your work and explain your process in the space below:
In order to convert binary to a decimal you must know how to read a binary number. In the positional system of binary, each bit (binary digit) is a power of 2. This means that every binary number could be represented as powers of 2, with the rightmost one being in the position of 20. Example: The binary number (1010)2 can also be written as follows: (1 * 23) + (0 * 22) + (1 * 21) + (0 * 20). You must move from right to left in the binary number, multiplying remainders by 2n+1 , starting with 20 . After you've written out your binary system, find the sum of it and that number is your decimal answer. Convert binary # 01100110 to decimal: ( 0 * 20 ) + ( 1 * 21 ) + ( 1 * 22 ) + ( 0 * 23 ) + ( 0 * 24 ) + ( 1 * 25 ) + ( 1 * 26 ) + ( 0 * 27 ) = 0 + 2 + 4 + 0 + 0 + 32 + 64 + 0 = 102 ( 0 1 1 0 0 1 1 0 )2 = ( 102 )10

Convert the decimal number 93 to binary. Show your work and explain your process in the space below:
The binary system is a two-base system using only (0,1) to represent all numbers. Take a decimal and divide it by 2 and then take its quotient and divide it by 2 and so on, repeating dividing the list of calculated quotients by 2. In order to determine whether a quotient deserves a 1 or 0 value, see if the quotient of each division had a remainder. For instance, 23 / 2 = 11.5 : Here, your quotient should be written as 11 and then you should say "Remainder is 1" because there is a .5 value left because 23 didn't get divided by 2 cleanly. If your quotient has a remainder then it gets a 1, if it divides cleanly like 2 / 2 = 1 for example, then it gets a 0 because the quotient had no remaining values/remainders. To convert decimal number 86 to binary: 93 / 2 = 46 : Remainder is 1 --> Least Significant Bit (LSB) 46 / 2 = 23 : Remainder is 0 23 / 2 = 11 : Remainder is 1 11 / 2 = 5 : Remainder is 1 5 / 2 = 2 : Remainder is 1 2 / 2 = 1 : Remainder is 0 1 / 2 = 0 : Remainder is 1 --> Most Significant Bit (MSB) Write the remainders from MSB to LSB: ( 93 )10 = ( 1 0 1 1 1 0 1 )2

A computer with more processors will run multiple programs faster than a computer with less processors.
True
Because it is base 2, binary usually requires a larger number of bits, or "digits", to represent a number than, for example, the base 10 decimal system.
True
By choosing TRUE for this question, I affirm the following: - I have read the E 115 syllabus - I have read the E 115 Policy Book - I have browsed through the Moodle and E 115 websites in their entirety.
