The file organization which allows us to read records that would fulfill the join condition by using one block read is a) Heap file organization b) Consecutive file organization c) Clustering file organization d) Hash file organization Answer: c 34.
The objective of the lab was to program a vehicle board so that an LED would flash at .5 Hertz. This was done by using the Arduino software tool, the Redbot library, and using theses to write a program that would satisfy the requirements. . The following code used consisted of the two functions void setup and void loop. The void setup function runs once in order to configure the mainboards input and output pins.
Our protocol takes two integers decomposed into encrypted bit vectors [a][b] and outputs the greater integer. In this configuration cloud 1 (C1) has the encrypted bit vectors of the integers being compared and cloud 2 (C2) knows the private key. The protocol is as follows in a very concise form. we can say with firm conviction that vector [Y] consist of encrypted zeros at every location except one location which holds the value of encrypted one. This distinct location identifies the first position where vector [a] and [b] differ.
Use this instance to specify the primitive polynomial that determines the connection structure of the linear feedback shift register (LFSR). total bits specifies the total number of pseudorandom bits to be generated. The default value is 128. PN sequence
Each packet of data on the network trips in one way and each device collects each box in turn until the journey 's end device receives it. • Linear; basically arranged out in a line, has a single cable joining all of nodes. If on node breaks down the whole system breaks
It can be used only to send and receive files. FTP uses two TCP ports. Port 20 for sending data and port 21 for sending control commands. It uses UDP port 69 for communication. FTP can use authentication and all data is sent in clear text.
The Bosch BNO055 IMU sensors come with the software package that consists of sensor drivers. In order to let the sensors to give data, these drivers should be added in the Arduino software library folder inside the computer. The driver is capable of giving the raw sensor data by using the sensor library in the Arduino code. The Arduino library used for this purpose was ‘Wire Library’, which allow communication with I^2 C devices. This library can be manually downloaded and added to the Arduino folder.
In most instances, a system administrator will be accessing and configuring devices on the network via SSH, and in some cases, if SSH is not accessible the administrator can be completely locked out of a server or network device. In the context of this lab, all devices are accessible via SSH over the internal, so I have implemented necessary monitoring using Nagios.
How many bits are required to address a 4M X 16 main memory if a) Main memory is byte addressable? ______ b) Main memory is word addressable? ______ 2. Suppose that a 16M X 16 main memory is built using 512K X 8 RAM chips and memory is word addressable. a) How many RAM chips are necessary?
MS SQL Server Page Compression can be applied to tables, table partitions, indexes and index partitions. This compression technique can be viewed as an enhanced version of Dictionary Encoding discussed in . The following two figures illustrate the effects of page compression on an uncompressed
(2x − 3y)^4=16x^4-96x^3y+216x^2y^2-216xy3+81y^4 5. The possible variable terms would have to be a2b3; a5b3; ab8; b8; a4b4; a8; ab7; a6b5 because the exponents of each one of the terms all add up to 8. Task 3 Q&A Using the Fundamental Theorem of Algebra, complete the following: 1. Determine how many, what type, and find the roots for f(x) = x4 + 21x2 − 100. 2.
A variable is very often described as a name for a place in the computer’s memory where you are able to store any data that you wish. The computer will automatically place these variables in different locations each time that the programme we are loading is run however the programme that we have loaded will know exactly where the computer has placed the data. We are able to do this by composing a variable to refer to it and then leave the computer the messy work of having to find out where it is actually located. For us it is much more important to be able to know exactly what type of data that we will be storing at that location. Variables however are temporary and only exist for the amount of time that they are actually necessary and will then be disposed of.
If dominant bit (0) - data frame and if recessive bit (1) - Remote Fame. IDE – A dominant single identifier extension (IDE) bit means that a standard CAN identifier with no extension is being transmitted. r0 – Reserved bit DLC – The 4-bit data length code (DLC) contains the number of bytes of data being transmitted. Valid values are 0 to 8. data – Up to 64 bits of application data may be transmitted.
