Show the steps of conversion that you used. -0011 0110 0011 represents 3 0110 represents 6 - 36 Exercise 1.3.6 Represent the hexadecimal value f6 16 in binary and decimal.
They are equivalent because they represent the powers of 10 3: Based on the breakdown of the decimal and binary systems in this lab, describe the available digit values and the first four digits of a base 5 numbering system. You can use the binary system as a reference, where the available digit values are 0 and 1 and the first four digits are 1, 2, 4, and 8. The digit values in a base numbering system are 1s and 0s. You are using 16, 8, 4, 2, 1 instead of 128, 64, 32, 16, 8, 4, 2, and 1. 4: Using the Internet and the Help files in Excel, explain why creating a converter from decimal to binary would be more difficult to construct.
A user has opened a word processor, typed the numbers123456789, and stored the document as a file called report1. Which of the following determines, in part, what bits the computer stores in the file to represent the text typed into the report? d. The binary equivalent of decimal 123456789 7. A user has opened a calculator application, typed the numbers 123456789, and then done some math problem using this number Which of the following determines, in part, what bits the computer stores in RAM to represent the number123456789? d. the binary equivalent of decimal 123456789 8.
110 (network ID), 10.10.1 (host) What are the binary values of the host ID and the network ID? Hint: You should use decimal-to- binary conversion skills on each octet of the address separately and chain the bytes together for the answer. 1101110.00001010.00001010.00000001 Exercise 8.1.2 Use your textbook and the Internet to complete Table 8- 1. Class | Range of 1st byte (octet) in decimal | Network ID | Host ID | Possible Networks | Possible Hosts per Network | A | 0-127 | A | b,c,d | 2^7 | 2^24 | B | 128-191 | a,b | c,d | 2^14 | 2^16 | C | 192-223 | a,b,c | D | 2^21 | 2^8 | Why is the number of possible networks for each class not equal to 2 raised to the power of the number of bits used for the network ID? It would require more bits Exercise 8.1.3 Would the IP address in Figure 8- 1 be valid as a class C address?
b,c 2. A PC NIC and a switch port create one electrical circuit to use when sending data. The sender creates a (maximum) 1-volt electrical signal with a frequency of 1000 hertz. Which of the following facts are also true? (Choose two answers.)
Given any input (a0,a1,a2,…a2n-1 describe the permutation of the leaves of the recursion tree. (Hint: write indices in binary and see what the relationship is of the bits of the ith element of the original sequence and the ith element of the resulting permutation of elements as they appear on the leaves on the recursion tree.) 3) Timing Problem in VLSI chips. Consider a complete balanced binary tree with n = 2k leaves. Each edge has an associate positive number that we call the length of this edge (see picture below).
Which of the following is true about the process of read data, as described in the chapter? The CPU tells the RAM which address holds the data that the CPU wants to read. 8. Which of the following is not a feature of a file system that might use with a hard disk drive? An actuator arm 13.
A COMPILER is a program that translates a high-level language program into a separate machine language program. An INTERPRETER is a program that both translates and executes the instructions in a high-level language program What type of software controls the internal operations of the computer’s hardware? An operating system controls the internal operations of the computer’s hardware Unit 1 Research Assignment 1 Algol (ALGOrithmic Language): 1960, Defined by an international consortium. Algol was the first language to be machine independence. It has many of the common language features, such as If-Then-Else, For and While loops, Switch with gotos, begin and end markers, local variables, etc.

To be able to show all 16 possible numbers 0-15 you can change the circuit so that the most significant bit (the eights place) is shown by an LED and the rest of the number is displayed on the MAN72, this would then be a successful binary to octal number system conversion circuit. Lab 4 – Logic Gates Materials: - 7400 quad 2-input NAND gate - 7402 quad 2-input NOR gate - Two 1.0 kΩ resistor Purpose: The purpose of this exercise was to set up a simple NAND or not and gate and a NOR, or not or, gate. Once set up, using one of the resistors to ground for a logic of one and a simple jump to ground for a logic of zero, the goal was to test the truth tables for these two gates. Procedure: The setup was incredibly simple, we simply set up and VCC’d the ICs and then began to test. The trouble came when our results were not matching the anticipated theoretical results.
