Data communication in a computer network refers to the process of transferring digital data between two or more devices connected within a network, allowing them to exchange information through a transmission medium like wires or wireless signals, essentially enabling communication between different computer systems by sending and receiving data packets across a network

What entails of psychology. How you can use psychology to understand human behaviour and the human perspectives.

Hardwired systems are inflexible. General purpose hardware can do different tasks, given correct control signals. Instead of re-wiring, supply a new set of control signals

Together with an explosive growth of the mobile applications and emerging of cloud computing concept, mobile cloud computing (MCC) has been introduced to be a potential technology for mobile services. MCC integrates the cloud computing into the mobile environment and overcomes obstacles related to the performance (e.g., battery life, storage, and bandwidth), environment (e.g., heterogeneity, scalability, and availability), and security (e.g., reliability and privacy) discussed in mobile computing. This paper gives a survey of MCC, which helps general readers have an overview of the .MCC including the definition, architecture, and applications. The issues, existing solutions, and approaches are presented. In addition, the future research directions of MCC are discussed. Copyright © 2011 John Wiley & Sons, Ltd

Data backups and cloud computing can be treated as two separate subjects in one context and can be considered as complementary in another context. Data backups have been common since the inception of computers. Cloud computing, on the other hand, is a relatively recent phenomenon. The cloud infrastructure helps with effective data backups and is a low-cost disaster recovery option. Data backups help in ensuring restoration of data in case of data loss, data corruption, and data integrity issues.

Cloud computing is a means by which computational power, storage, collaboration infrastructure, business processes and applications can be delivered as a utility, that is, a service or collection of services that meet your demands. The aspect of pay-as-you-go in the cloud is referred to as elasticity and is an extremely important concept within cloud computing. On the whole, the cloud is basically an umbrella term that covers on-demand access to various computing resources. XaaS (Anything-as-a-Service) - This is a generic term which refers to any service which is available as cloud enabled service through internet. Some time it is also called ‘everything-as-a-service Backend-as-a-Service (BaaS) – Backend as a service (BaaS), or mobile backend as a service (mBaaS) is a model of cloud computing in which the vendor provides web and mobile application developers with tools and services to create a cloud backend for their applications. BaaS vendors typically use custom SDKs and APIs to give developers the ability to connect their applications to backend cloud storage and features such as user management, push notifications, and social network integration. Cloud Foundry – Cloud Foundry is an open-source cloud platform as a service that was originally developed as a joint venture between VMware, EMC, and General Electric, and is now owned by Pivotal Software. Cloud Management Platform (CMP) – A cloud management platform (CMP) is a product that gives the user integrated management of public, private, and hybrid cloud environments. Cloud Marketplace - A cloud marketplace is an online marketplace, operated by a cloud service provider (CSP), where customers can browse and subscribe to software applications and developer services that are built on, integrate with, or supplement the CSP’s main offering. Amazon’s AWS . Marketplace and Microsoft’s Azure store are examples of cloud marketplaces. Cloud Washing – Cloud washing is a deceptive marketing technique used to rebrand old products by connecting them to the cloud, or at least to the term cloud. Grid computing is a group of networked computers that work together as a virtual supercomputer to perform large tasks, such as analyzing huge sets of data or weather modeling. Through the cloud, you can assemble and use vast computer grids for specific time periods and purposes, paying, if necessary, only for what you use to save both the time and expense of purchasing and deploying the necessary resources yourself. Also by splitting tasks over multiple mac

We’ve said it time and time again, menswear is ruled by history and tradition. Every person in menswear (designer, stylist, editor, etc) has taken inspiration from the past at one time or another. And no era has been overlooked. Therefore, as we continue to explore the foundations of personal style, I thought we’d take a quick look back at the last hundred-or-so years in men’s fashion. Perhaps this will provide a little insight or context as to how menswear shifts, and more importantly, how we can make informed decisions when it comes to buying clothing and developing personal style.

Exhibition planning 02 First steps Stakeholders and local connections Exhibition proposal Selecting the objects Borrowing objects Designing the layout Assess your objects’ display requirements

An exhibition designer is responsible for creating fixtures and displays for various exhibitions, hosted by museums, shows, libraries, galleries, organizations or as part of a larger show. Some work independently, while others work for a single institution, such as a museum, private company or art gallery. The scope of exhibition display includes spatial arrangement, installation design, as well as the visual and contentual aspects of presenting information. Exhibition display is the physical and interpretative environment, in and through which artworks and artefacts are presented. Exhibition designis the process of conveying information through visual storytelling and environment. The main difference between exhibition and gallery is that an exhibition is a public display of art or items of interest, while a gallery is a place we use for the display or sale of works of art. Exhibition and gallery are quite common words in the world of art. Although these two words are often interconnected, they are not the same. A gallery is a place where art is sold or displayed, while an exhibition is an event that involves displaying arts or other items.

A special fabric may be distinguished because of:- I. Its weight ii. Its texture iii. A decorative design iv. Its purpose e.g. bridal, evening or swim wear. A special fabric may require different handling techniques from the normal sewing practices. The special technique may include extra steps, planning unique pattern layout, omitting interfacings, topstitching hems or using special sewing equipment.

This textile testing laboratory manual is to be used with the textile testing teaching manual and any other text on textiles. The student is encouraged to read widely to supplement the information obtained from the results and be in a better position to answer the questions that follow each laboratory. Knowledge obtained will be useful to the pursuit of a successful career in apparel production, textile manufacturing, garment designing, retail buyers, choice and selection of textile products etc. This manual will be important to the students as well as the instructors. For easy usage the manual is divided into three main parts namely: i.Test for fibers ii.Tests for yarns Tests for fabrics

This section is organized into two main parts, namely: i. Trimming of apparel, and ii. Renovation of apparel TRIMMING OF APPAREL Trimming refers to the decoration of a garment. It is the process of making a garment more beautiful or interesting, using accessories or garment details that are decorative as well as functional. Examples of accessories are the parts of a garment that are not part of its basic structure such as buttons, cuffs or collars. Garment details are trims that are added to the basic garment such as ribbons and appliqué. Details can either be bought ready made, or the garment maker can make them. Trimmings can be used when designing a garment, or they can be added to an old garment to improve its look. Trimming calls for one to be creative and imaginative so as to come up with an interesting look
