A workgroup is also referred to as a peer-to-peer network. In a peer-to-peer network, all the computers in a workgroup share resources as equals, without a dedicated server. The main design features of work groups are that the administration of user accounts and resource security in a Windows XP workgroup are decentralized. Each computer on the network maintains a local security database. This database lists user accounts and resource security information for the computer on which the database resides.
“Cloud computing” is a term used to describe massively scalable, hosted computing that is made available to all consumers (individuals, small-business, enterprises). Several factors, including the decline in data transport costs, hardware virtualization, and multicore CPUs, and the proliferation of MIDs (mobile internet devices) have contributed to the growth of cloud computing. Further, the popularization and proliferation of web based email, calendars, and collaborative office productivity applications has fostered a new market for cloud computing (Siegel, 2008). In my opinion the new EC2 is a low risk
Intro to Personal Computers - TB143J Unit 6 Research Paper 1: Network Attach Storage Explanation of Network Attach Storage device A Network Attach Storage device is a server that is dedicated to file sharing only without the use of fully-functional operating system. This type of server, which is a single hardware device follows the client/server design and allows data access/retrieval by clients. Network Attach Storage is often a specialized computer built from the ground up for storing and serving files across a network that usually already utilizes servers but does not require maintenance and upgrades. What is the speed of the network adapter available on a NAS device? Speed may vary depending upon how relatively new or old the device is.
Running Head: SYSTEMS CONSIDERATION IN HRIS Assignment 1: Systems Consideration in HRIS Sylvia Armstrong Dr. Matthew Gonzalez HRM 520 – Human Resource Information Systems April 22, 2012 1. Use the internet to research and evaluate two (2) commercial HR database systems for your organization. Evaluate the advantages and disadvantages of each system and, and base on your knowledge of human resources and database systems, propose one (1) package that would fit the needs of your organization. Suggest three (3) specific reasons why you would recommend that system over the other. Most HRIS rely on an underlying database.
Applications are software as a service (Saas), these applications can provide us with sophisticated capabilities from servers which can be accessed across the internet, without the need to download software applications to the local device. It is also used for review performances. Platform (Paas) refers to the intermediate layer which are in place for businesses to create these applications and websites. The last part of the diagram of cloud- computing is; Infrastructure which is Hardware as a service (Haas) which allows smaller businesses to buy large amounts of computing power for short periods. This allows these smaller businesses/companies to compete with the larger enterprises.
Iron Dragon has the skillset necessary to perform break/fix work on a variety of equipment. There are many companies who focus on one or two lines of work, meaning that they only work on computers, on networks, on printers, or some other such equipment and rely solely on those few areas. Iron Dragon, on the other hand, will perform break/fix work on computers, printers, servers, POS equipment, peripherals, televisions, precision hand tools (such as micrometers and calipers), and optical measuring equipment as a large part of its break/fix services. Another of Iron Dragon’s strengths is its partnership with Dell. This is seen as a strength because Iron Dragon now has the capability of selling computers, servers, parts, and services directly to customers and (hopefully) opening up another source of revenue for the company.
To communicate with the network, the NAS system uses TCP/IP protocol and is often managed via a web browser interface. Storage can easily be added to the NAS system without worry about network downtime. An NAS system can also be easily configured to make use Raid arrays and scheduled backups and therefore seamlessly guarantee that data is safe at all times. Storage area networks share many of the advantages offered by NAS devices. The factor that differentiates SAN and NAS is the scale through which each can be used.
Compare and Contrast Laptop Computers and Desktops Having to choose between a Laptop Computer or a desktop is difficult choice that one is faced especially if it is for personal use.
