- Suppose you want to send the following 2 16-bits numbers: 11010010 01111010 and 10011010 01011001. What would be the checksum? The spaces are used to make the sequence of bits more readable. Options: A) 01101100 00101011 B) 1001001100101011 C) 10010011 11010100 D) 01101100 11010100arrow_forward4. The largest number with two-byte word length is: Ans: 5. How many lines needed in parallel representation to transimmit decimal integer values up to 17 in binary. Ans: is (2), -Q₁. 6. The base of the following is Ans:arrow_forwardAssume a 32-bit binary 01000101 01000101 01000011 01010011. Write down what value will the given binary represents if its type is a: 1. 32-bit unsigned integer, 2. four characters in ASCII code, 3. 32-bit floating point number (keep mantissa up to 4 decimal places).arrow_forward
- Find the decimal values of the following signed (negative) numbers. First find a signed-magnitude binaryrepresentation for them and then convert them to decimal numbers: a. (71)8= (111001)2 signed-magnitude =b. (80C)16 = (100000001100)2 signed-magnitude =c. (10100101)2 = (-0100101)2 signed-magnitude =arrow_forwardThe table below is similar to the one in Part A, but this time each row provides a decimal value. For each row, provide the equivalent binary value in the second column. And again, please provide your final answer in the table and show and submit all your work on a separate page. Base 2 (Binary) Туре unsigned byte unsigned byte byte byte Base 10 (Decimal) 204 17 65 -90arrow_forwardA computer byte consists of eight bits, each bit being either a 0 or a 1. Assume that characters are represented using a code that uses a byte for each character. Some written languages, such as Chinese and Japanese, use tens of thousands of different characters. If a language uses roughly 78,000 characters, a computer code for this language would have to use how many bytes per character? x bytes Need Help?
