How does the throughput of pci express version 1.1 compare to pcie version 1?
1.1 and 1 were the same allowing up to 16 lanes at 250 MB /sec per lane in each direction, Version 2 allowed up to 32 lanes on one slot and up to 500 MB/ sec per lane in each direction
Elements of computing process?
Basic Computer Elements: In generally used computers one can find that there are four basic computer elements following are the elements.
(1) ALU (Arithmetic Logic Unit): The ALU is the digital circuit that is able to perform different types of functions, such as Addition, Subtraction, and Multiplication etc.
(2) Control Unit: The control unit is the part of CPU (central processing unit) or other devices that performs the duty to direct its operations, the control unit is just like a finite state machine that has some finite states and the transaction from one state to the other state is called action.
(3) Memory: The memory is another very important element of the computer without memory the computer can't operate in today's modern age it is called the RAM (Random Access Memory) when ever we give some instruction to the computer it passes through RAM to the Processor and the processor processes it and send it back. The main reason behind memory is that it is faster in communication with the processor then the other memory devices such as hard disk etc.
(4) Input/output devices: The input and output devices is another important element for example the processor is the input device and it gives its output to the monitor etc for output.
There is another very important point the basic elements are considered as CPU (central Processing Unit), I/O devices, and Memory actually the CPU is the composition of different other elements such as ALU, Control Unit, Registers which is another type of memory.
What kind of chip did Steve Fodor develop that you can't eat?
He does research in biometrics and DNA analysis, observing detecting and analysing the human genome.
He constructed high-density arrays of peptides and oligonucleotides on small glass substrates (chips). These arrays enable millions of assays to be carried out in a rapid parallel format.
These DNA chips are used in many areas of basic and clinical research, including the detection of drug resistance mutations in infectious organisms
yes, it can. All you need is laptop that has an VGA or HDMI output, which most of the newer laptop do. Once you connect to your TV, an instruction window will appear in your laptop. If not hold down fn f5
Hope this help.
How many extended partitions can be created in a hard drive?
Ther can only be one Extended Partition per hard drive
semiconductor image sensors
these are special photo sensing sensors,these are very big deep areas to explain here how these sensor capture, it
but simple answer for you
these are simply found in digital cameras webcams phone camaeras,
according to image it will produce some electrical signals and it will be collected by associated electronic circuit then it will be sent to image processor,it the it will be displayed in the proper image viewing element
What is the function of a PATA cable?
A sata cable connects a motherboard to a Sata hard drive. Modern power supplies have special chords made to power Sata hard drives where as old ones do not. Older computers have Eide cables to connect the motherboard to the hard drive.
Microsoft early start began in Albuquerque, NM in March 1975. Microsoft is headquartered in Redmond, Washington, 13 miles from Seattle.
Connector at the end of the Ethernet cable?
The one that looks like an over-sized phone plug is called "RJ-45"
What is basic computer maintenance?
This is where the user maintains the computer without it being on the systems scheduled
list of things to do.
EG. Checking all the components are in working order
A microphone has a voltage output and an acoustical input. Only the sound wave can move the diaphragm of the microphone and a voltage signal comes out. That goes to to an amplifier and to a loudspeaker.
What is the name of the hardware component that enables a computer to send and receive data?
This could be a modem or network card most commonly, but can also be a large number of other devices. It depends on the method of sending and receiving- A CD burner or floppy drive can send and receive data, just not in an entirely automated process.
Buses are the set of wires that carry special information to or from the CPU. There are three types of buses
they are:
1. Address buses: these buses carry address given by the CPU from one unit to another in the computer.
2. Data buses: These buses carry data from one unit to other, it is a bi-directional bus i.e the data can be carried in both directions.
3. Control signal: These buses carry control signal from ALU to memory and from memory to alu and then to the output unit.
Factors to consider when acquiring hardware or software for your computer?
it is very simple. First, make sure the speed of the computer is tolerable. Second, check how much memory it has. the more memory, the better. Third, check the price. Always compare, and try to find the unit rates of how much youre spending. Fourth, check the physical features, like shape, size, and weight. Fifth, always try to make sure a compuetr has WiFi for wireless internet.
If you test all these factors, and you like it all, the computer will be perfect for you!
answ2. Only buy a machine with features that suit your needs. Even so, it will be obsolete in 5 years. it is not a lifetime investment.
How many types of bios do you have?
You generally have 1 BIOS on your computer, typically an Award Pheonix BIOS or some sort of proprietary BIOS developed by either the computer manufacturer or the motherboard manufacturer. In some of the newer cases, being with the iMacs and a select few new motherboards, there isn't a BIOS at all, but rather a advanced replacement known as an EFI. The concept of the EFI is very controversial because it creates new, unneeded complexities to the startup process at the expense of simpler setup and loadup GUIs. Haters of the EFI system (such as myself), tend to state that your loadup system isn't supposed to be used for normal computing and doesn't need things like this. We also like to use the old adage, "If it isn't broke, don't fix it."
What is difference between a Graphic card and Video card?
A graphics card, video card, v card, video board, video display board, display adapter, video adapter, or graphics adapter is a computer component designed to convert the logical representation of visual information into a signal that can be used as input for a display medium. Displays are most often a monitor, but use of LCD TV, HDTVs, and projectors is growing increasingly common with the growth of the media center computer concept. The graphics card and display medium are able to communicate utilizing a variety of display standards. Graphics card are both integrated into motherboards, and sold as expansion cards........ wow this guy just copied this from a dictionary
What are some input devices for the computer?
input devices are used to enter the data/commands/information so that we can get the result.

How do you destroy a DVD or CD?
Put it in the microwave.... commonly used by people in the military to destroy electronic documents... It won't hurt your microwave either,
They are just made (mostly) of thin plastic, so you can break them fairly easily if that is what you want to do. If you are trying to avoid destroying them, I recommend that you keep them dry. Water can damage them. Don't store them in direct sunlight, either.
What are the different types of buses in computer?
Silly answer - They come in many varieties, both double decker and single. Some even have open roofs!
More serious - There are a number of type of PC buses.
Front side bus, QuickPath Interconnect (QPI), or HyperTransport bus (HT): This connects the CPU to the memory controller or northbridge chip. However, in the HT and QPI implementations, the memory controller is a part of the CPU, freeing up the bandwidth of the bus for other things.
LPC bus: Used to connect the system BIOS, super I/O controller (keyboard, mouse, serial, parallel, floppy), and even a trusted platform module (TPM) to the southbridge chip.
Memory bus: This connects the memory to the memory controller, northbridge chip, or CPU.
Peripheral buses: These connect the motherboard to peripheral cards. This includes ISA, EISA, VLB, PCI, AGP, PCIe, etc.
What things use series circuits?
Christmas tree lights.
LIGHTS for Christmas do not need to in series but conveniently in series saves power.
A regulator while usually is in series does not be in series to regulate. FINALLY everything eventually are connected in series. from 475kv transmission to the local home device.
Consideration of choosing network topology?
Considerations for selecting a topologySelecting an appropriate topology for your deployment environment depends upon several factors.
When you select a topology pattern, consider the following factors:
- Available hardware resources
- Application invocation patterns
- Types of business processes that you plan to implement (interruptible versus non-interruptible)
- How heavily you intend to use the Common Event Infrastructure (CEI)
- Individual scalability requirements
- Administrative effort involved
