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.
ATX uses P1 Power and supports both the 20 and 24 pin connectors. Mice and keyboards use either the PS/2 or USB connectors. The memory slots are DIMM. The expansion slots are either PCI or AGP. It also contains 2 IDE connectors and 1 or 2 SATA connectors.
Which of the following answers best describes how a hard disk drive physically writes a binary 0 or 1?C. changing the disk’s surface 12. Which of the following answers are true about an internal hard disk drive (HDD) as it is normally used inside a personal computer (choose 2) B. used for long-term memory, D. connects to the CPU over a bus using a cable
A word processor may also refer to a stand-alone computer unit similar to a typewriter, but frequently including technological advancements such as a screen, advanced formatting and printing options, and the ability to save documents onto memory cards or diskettes. Word processors almost invariably allowed the user to choose between standard typing and word processing modes by way of a switch. Such word processors should not be confused with an electric typewriter shows the graphical user interface of the Microsoft Word
NT1430 Unit 2 Discuss The Second Extended File System (EXT2) file system is a replacement of the Extended File System (EXT). The file system was created by Rémy Card in 1993. EXT2 was the default file system for Linux until EXT3 came along. EXT2 still is a favored file system for Flash and USB drives due the lack of journaling. Journaling requires more writes to the storage unit and can be slow on these external devices.

Provide a comparison table showing the similarities and differences between Desktop and notebook computers Similarities | Differences | Functionality: Both types of computers provide expansion ports, CD/DVD drives, keyboards, mouse, both audio output and visual display | Power Source: The desktop computer extracts power from the wall outlet and may provide hundreds of watts of power whereas a laptop relies upon a rechargeable battery for power | Software: Both types of computers can run on the same operating system and application programs. | Size: The desktop computer sits on a hard surface and is not easily portable. The notebook computer sits on the top of a hard surface or upon your lap and is easily portable. | Power Saving: Both types of computers can hibernate or sleep when not in use. | Components: The internal components of a desktop computer are not designed for low power operation.
There are priced versions for Linux also, but they are normally cheaper than Windows. | For desktop or home use, Windows can be expensive. A single copy can cost around $50 to $ 450 depending on the version of Windows. | Development and Distribution: | Linux is developed by Open Source development i.e. through sharing and collaboration of code and features through forums etc and it is distributed by various vendors such as Debian, Red Hat, SUSE, Ubuntu, GentuX etc.
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
Alton Kerry 18470825 Unit 4 Research Paper – Port Expander A port expander is computer hardware that allows you to plug more than one device into a single port. It can be any device that takes one existing port and makes multiple ports out of it. There are two basic forms, internal expander which has a connection typically to the motherboard, and an external expander which plugs into the existing port which then has multiple ports. When not part of a computer, these devices are known as splitters. In the non-computer world splitters are very common, such as an extension cord or a power strip.
