Software: Software is a set of programs that are executed in hardware. Moreover, software is a set of hardware instructions and their representations, which we call programs. The American heritage dictionary defines software as: “Written or printed data such as programs, routines and symbolic languages, essential to the operation of computers.” Software is anything that controls hardware. Software does not exist solely inside a computer. It is anything non-touchable, non- viable set of…

designed to make building manufacturing work control, easy and flexible. This system binds Multiple-Application Software Modules, referred as “Agent”. 4. The Glue Logic consists of two major parts: 1. The communication interface subsystem 2. The data management subsystem 5. The communication interface exchanges information with agents running in both the same work-cell controller and remote work-cell controller connected with the network system Working of…

P5: Set up a standalone computer system, installing hardware and software components P6: Configure a computer system to meet user needs P7: Test a computer system for functionality • In this picture you can see all the parts are missing. They were removed so that we can put it back together. • In the next picture you can see the RAM is placed in the slot. It is positioned in with small amount of force until the clips click into to place. • In the next picture we installed in the…

THE DEFERENCES OF HANDLING SOCKET AND SERVERSOCKET First of all what is a socket? A socket is the one end –point of two-way communication link between two programs running over the network. This means the programs run on different computers, usually referred as the local and the remote computer. However, one can run the two programs on the same computer. Such communicating programs constitute a client/server application normally; a server runs on a specific computer and has a socket that is…

Ngobeh Prof. Saunders Review Question Lab September 23, 2015 1. Move copies data from one memory location or register to another. The term “move” is a misnomer because data values in the source location aren’t removed. They’re tested, and copies of these values are placed in the destination location. Therefore, a move operator is really a copy operator. 2. Access to data stored in registers is immediate, but access to data stored in memory locations is slower. Most programs require a temporary…

The organization had total three possible solutions for the problems they were facing. The first solution was Google drive which is considered as a good alternative in place for an enterprise program. The second solution is WordPress which has blogs, websites and online publications and also has an easy-to-use content management system which allows from drafting articles to scheduling of posts. The third solution which the organization finally adopted to solve the problems was the SharePoint.…

An entity relationship diagram is a graphical representation of conceptual data organized into a specific and well-defined model.. The objective of an entity relationship diagram is to construct a simple, easy to comprehend, and accessible presented data model consisting of entities, attributes, relationships and cardinalities. The model serves as an instrumental tool for database design, where the model can facilitate communication between the system analyst and the end-user during the…

design and age. Older model equipment built more than 10 years ago will run at 10Mbps, devices built in the last ten years run at least 100Mbps. Generally, the speed determines how much data can be transferred throughout the network. The network devices are connected together via network switches that forward packets of data to the correct destinations. Switches and devices are able to auto detect the highest speed that the device or switch is in connection with to support and adjust to run at…

physical parts of a computer, is one factor that has been constantly changing throughout the development of computers. Two elements of hardware in particular have progressed as generations go on: data transfer and storage. One challenge for computer engineers from the start was deciding how to transfer data through the computer. The first computer, the ENIAC, required 18,000 vacuum tubes to do so, and weighed about 20 tons. Because of its huge size, its power consumption was 150,000 watts…

in 1946; it was call the William Tube. It only holds 1024 bits of data. In 1950s, magnetic technology came along with tape and hard disk storage. Magnetic tape became more popular because it was cheaper to produce and more reliable comparing to the hard disk at the time. One big draw back for the magnetic storage was it is slow and the data reading is sequential which means the computer cannot skip to access a certain piece of data. Magnetic disk technology developed into many forms, a popular…
