Computer Hardware

Motherboard (to attach everything to)

Power Supply (for power to the machine)

Processor (must be compatible with motherboard. Computes machine code.)

heatsink (comes with processor, aftermarket coolers are available.)

Memory [RAM] (must be compatible with motherboard. DDR3 is the new standard)

Hard Drive (whether it be a solid state drive or a hard disk drive, this is what the programs and files are saved to.)

OPTIONAL

Optical drive (to install Windows OS and run CDs or DVDs)

Video Card (to boost GPU performance)

Sound card (increase and have fuller, richer sound)

The one with the output of 5v 800ma as this will charge devices quicker and overheat less.

A video card or video adapter translates binary data into images.

the Monitor either doesn't come with speakers, Then you have to buy some.

Hope this helped you :)

A standard USB port (non 3.0) can provide up to 500mAh of power. This is on full power mode.

A 3.0 port can, if plugged into a 3.0 device, provide up to 900mAh if configured to do so.

It controls the part of the external data bus connected to the expansion slots.

Tactile (you physically feel the results.)

Floppy Drive, Pen Drive, CD/DVD are called as a consumable hardware.

You can go to your local computer and network builder and see what he has in stock and try to match it to your bays. Trying to get a bespoke one is going to be prohibitively expensive. Ripping one off an old case might well be your only option.

A monitor is not normally considered hardware, the internal components of a computer are considered hardware.

One of your drives has an error (known or unknown)

An electronic tool that allows information to be inputs process and output is called?

ports of a computer and its functions

The physical parts of a computer are all called hardware. That is opposed to ideas and invisible code called software that are encoded on a physical medium. Even a diskette or CD is technically considered hardware, while the data which is stored on it is software.

RJ stands for registered jack. There are a no. of RJ's that we use for e.g., RJ-9 ,RJ-11 RJ-12, RJ-45, RJ-48 etc

The BIOS chip is located on the motherboard

If you are using the original power adapter, it isn't damaged, and just started getting this message, it is almost certainly the power receiver inside your laptop that has developed a bad connection with your motherboard. You can try applying some pressure to plug that you insert into the laptop and you may see the "plug" or "charging" icon replace the "battery" icon in your sys-tray because you've improved the broken connection. The laptop will need to be opened up and serviced by technician who can solder a new receiver to the mother board.

This is a design flaw on almost every laptop I've seen, other than MacBook. Apple replaced the very vulnerable, standard pin & barrel connection with magnetic coupling that will break away without damaging either laptop or power cord. You can also use a MacBook on your lap without worrying about covering up any airflow vents on the underside - the other major design flaw with practically every other laptop out there.

HOW DO U NOT NO THI8S ITS A GaMeR HEADSET U ASRSHOLL DUMMY IN THE3 FACE. U STUPE U KOOKY BITKH U COULDNT SPELL MEEM IF U TRIED 😵😵😵😵😵. ALL PEPLE R DUMMYS. Y!!!!. UY R DA BIGGEST BOOBE I EVER SEAN. U R SO00000 STUPE THAT I DONT WANNER TIPE STUPID. #DUMM #ANOINGG #MADD #SAD #GLAD, MINIONS 4 LEIF OUT.

To know what size power supply you need, add up the wattage requirements of all components and add 30 percent.

types of network interface card

If you wanted more slots im pretty sure you would have to install a new mother board with more PCI slots

A USB Cable can have multiple types of plug ends which are called connectors (Standard-A, Standard-B, Mini-B, Micro-A, Micro-B, and Micro-AB).

Obviously there are wires between the two connectors and they are:

One wire contains a path for a 5V power supply

Two wires are twisted-pair data wires

One wire is the ground

A good general rule is that any electronic is only *designed* to last for the duration of it's warranty, and not much longer.

My two 2wires lasted 2, and 3+ years respectively. The first had to be replaced because Qwest upgraded their DSL, making it incompatible.

No vaselating' what the default output device means is newtral...

Different CPU designs use many different pipelining models with varying numbers of stages. The more stages, the more powerful your CPU is likely to be, but it is also much more complicated to design. Typical stages go like this:

1. Calculate next execution address (often just incrementing the address pointer, and not needing a separate pipeline stage)

2. Fetch instruction

3. Decode instruction

4. Calculate operand address(es)

5. Fetch operands

6. Perform operation.

Some of these stages may be absorbed into a single step.

If an instruction in the pipeline is conditional (such as branch if zero), the condition may not be known for a while, because the calculation that produces it can be still in the pipeline when the result is needed. Then the pipe has to be "stalled" until the test can be completed (inefficient!) or a guess is made as to the outcome and if it later turns out wrong then the pipe has to be cleared and some of the instructions re-executed. This is very messy!

In a modern CPU this is further complicated by such things as cache memory where recently used instructions and data are kept to save having to fetch them from main memory, also pre-fetch which gets several extra instructions from memory ready to be executed when needed. Hyper-threading can also be provided; broadly, this looks for execution cycles that can't be used because the pipeline is stalled, and runs a different program to take advantage of the spare time. It looks a bit like a second CPU with 30% or so of additional performance.

So the answer to your question is: it depends on the CPU, but typically the first stage is to fetch the next opcode from memory
