A local application is a program such as a word processor or a spread sheet that is stored on a local computer and runs only on that local computer. A network application is one that is designed to run over a network such as the internet, or a small or large network of connected computers, it has two components one that runs on the local computer and one that runs on a network computer such as email. 4. [pic] 5. List the six common types of computers available.

Stafone Jefferson Unit4Assignment1 Motherboard specifically refers to a PCB with expansion capability - the board is the "mother" of all components attached to it, which often include sound cards, video cards, network cards, hard drives or other forms of persistent storage, TV tuner cards, cards providing extra USB or Firewire slots, and a variety of other custom components. A motherboard provides the electrical connections by which the other components of the system communicate. Unlike a backplane, it also contains the central processing unit and hosts other subsystems and devices. Motherboard Most important consideration * Motherboard CPU Size and Shape * Determined by form factor ATX Form Factor * Replaced older AT form factor * Smaller * Better Organization * Easier to work on * Support for variety of I/O Devices Soft Power Switch * Front of Computer * Does not immediately cut power * Allows Normal OS shutdown process Power Switch * Back of computer * Immediately kills all power Wake on LAN * Configured in CMOS * Keyboard * Network Activity
Power saving: both types of computers can hibernate or sleep when not being used. Components: the internal components of a desktop computer are not designed of low power operation. This includes the CPU, which is Vulnerability: both types of computers are vulnerable to malicious code if not properly protected. Communications: Notebooks computers typically have infrared port and built-in video cameras and microphones, whereas these devices are add-nos for desktop computers. Unit 1 Assignment 1: Integrated Circuit Technology Assignment Requirements 1.
Many control panels are included as part of the Windows operating system, but others can be installed by third-party applications or utilities. For example, if you add a new mouse to your computer, it may come with a CD for installing a control panel specific for that mouse. Some graphics cards may also install an additional control panel that gives the user greater control over the computer's visual settings. Regardless of when control panels are installed, they can always be found within the Control Panel folder. The Windows Control Panel can be accessed by clicking the Start menu and selecting Control Panel.
Assignment 1 Computer Hardware Printer Video Video 1.07 Summary: Computer PC uses verity of Ports and connectors to communicate between devices and computer. These ports and connectors come in verity of shapes and sizes. Some of ports and connectors are serial port, parallel port, PS2, VGA, network interface cards RJ-45, modem RJ-11, USB, SCSI, firewall, and multimedia ports. Some of the devices and application which uses these ports are printer, keyboard, mouse, gaming joysticks, network, internet, monitor, and multimedia speakers or microphones. This video explains the purpose of the ports and devices.
A port expander is a device that allows one port on a computer system to connect to multiple devices. There are two basic forms of port expanders: internal and external. An internal expander has a connection inside the computer, typically on the motherboard, and the only part the user sees is the expansion plate containing multiple ports. An external device plugs into the existing port and then has multiple places to connect. When not part of a computer system, these devices are commonly known as splitters.
Similarly, pupil records may be stored by class, and then by pupil surname, which enables teachers and support staff to view or add to the individual records. In addition, documents (such as application forms for after school clubs, or medical leave forms) which need to be readily to hand for members of staff and/or customers to fill out may be stored in a filing cabinet equipped with labels on the outside of the drawers. This means that they can be easily located and given out as and when required. The second method, that of storing information electronically, is used for a wide range of documents and data. It allows a large amount of information to be stored without using up the often limited office space.
The CCNA exam covers all the topics in both ICND1 and ICND2—no more, no less. Types of Questions on the Exams The ICND1, ICND2, and CCNA exams all follow the same general format. At the testing center, you will sit in a quiet room with a PC. Before the exam timer begins, you will have a chance to do a few other tasks on the PC—for example, you can take a sample quiz just to get accustomed to the PC and the testing engine. Anyone who has user-level skills in getting around a PC should have no problems with the testing environment.
Documentation Styles Tennisha Johnson Everest University Documentation Styles A documentation style is a standard approach to the citation of sources that the author of a paper has consulted, abstracted, or quoted from (What are documentation styles, 2012, para 1).
