(Choose two answers.) a,c 3. A PC NIC and a switch port create one electrical circuit to use when sending data from the PC to the switch. Which of the following tasks is a function done by the transmitter? (Choose two answers.)
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
Unit 1 Assignment 1 Why is the CPU the most important component in a computer? The CPU is the part of the computer that actually runs the programs What number does a bit that is turned on represent? What number does a bit that is turned off represent? 1 represents a bit that is turned ON. 0 represents a bit that is turned OFF What would you call a device that works with binary data?
The Gigabyte GA-H55M-UD2H Motherboard features several innovations including the ability to charge iPhones and iPads even when the PC is off. A few additional Power management features, faster booting features, CPU overclocking, even a higher amount of copper used. Task 2 Examine board image. The AMD 770 Northbridge Chipset supports the AMD Phenom family of processors. It’s purpose is the Northbridge processor.
INTEGRATED CIRCUIT TECHNOLOGY (1961-PRESENT) An integrated circuit which is also known as (microchip, chip, IC) placed transistors, capacitors, resistors, and wiring circuitry, which was separated previously, onto the semiconductor material of a single chip (Germanium or Silicon). The cost of making electronics was greatly reduced due to the integrated circuit, which impacted the designs of all future computers and other electronics. AMD and Intel, two major microprocessor companies, dominate computers of today. The latest available offerings from Intel as an example contains transistors into the billions and compare this to the 1971 Intel 4004 chip, it contained 2,300 transistors. The Pentium chip which is the most common 1993 chip from Intel contained 3,100,000 transistors.
Jason Maysonet (16009681) 2/15/13 TB143 Unit 8 Analysis 1: System Performance OK, you know that the CPU, the RAM, the Video Card Processor or GPU and Video Card RAM or VRAM all determine the performance of the system – to a certain extent. And you also know that the performance impact of changing one component is dependent on the motherboard and other existing components, for example, you cannot simply continually increase CPU speed and think that you current computer will simply keep on getting faster and faster, but how do these different components interact with one another in terms of performance impact? Also, we know that more RAM is in general always better, but we also know that 32-bit computing systems can’t really sensibly make use of more than 3.2GB RAM. So it’s all good to try and smack 16Gigs of RAM into your 32-bit Windows XP machine, but it will be a total waste of money on 13GB of RAM. Also we know that more processes running on your computer will in general mean less CPU’s horsepower available for other tasks.
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.
3. Provide a comparison table showing the similarities and differences between desktop and notebook computers. Task1: Here are the functions of the each component in the Von Neumann model of the computer Component Function Control unit The control unit will manage the process of moving date and program that data. In modern computers this memory is RAM. Arithmetic logic Unit This part of the architecture is solely involved with carrying out calculations upon the date.
Question 20 ____ refers to the amount of computer support that exists for the functions that are included in the new application system. Question 21 A(n) ____ is a field or set of fields stored in one table that also exists as a primary key in another table. Question 22 Which company first built a computer based on the Xerox Star’s graphical user interface (GUI)? Question 23 ____ describes any network over one kilometer. Question 24 ____ testing examines the behavior of an entire subsystem or independent subsystem with respect to technical and user requirements.
CIS 105 Week 3 DQS CIS 105 DQ 1 There are a variety of computers available, from the smallest computer in a domestic device to the supercomputers used in industry. Despite the different uses for computers, they all have basics elements in common—each computer system involves hardware, software, data, and users. Think about the role of each component of your home or work computer: How do the components of your computer system interact within the system? What improvements or additions to your system do you think would benefit you or make the system more user-friendly?
