Computer Hardware

The computer allowed the presses to run faster and operate more precisely, creating a need for automatic systems and robot loaders and unloaders.

The shell relates to the user and to application and provides a command menu or icon interface, whereas the kernel is responsible for interfacing with the hardware.

There is a step by step guide (with screenshots) on how to fix this hole at the website below.

**edited the previous post as it was very very long and essentially were cuts from forums. I think that it will be more useful if you have a direct guide instead of having a post that was simply a collaboration of other people's forum posts. I give my regards to the previous poster. Feel free to use the previous post if you believe that that was more useful.

speakers is sound which is actually data

Yes it does. I paid for it $300 and its not worth that much. A lot of fun and really amazing but i dont think you will be able to actually implement his ideas to your daily life. Again very interesting but useless

transmit is a type of light ray. what type i dont know

input

scanf() , getch() , getche()

output

printf() , putch() , putchar()

ENIAC, short for the Electronic Numerical Integrator and Computer, was the first electronic computer. It was capable of solving?æcomplex arithmetic problems, including those involving loops, branches, and subroutines.

Because it is the conductor for the symphony of parts in a computer - it times and relates data from this part, transfers out data from this one, pulls in from this one.... It's probably closer to a traffic cop than a heart.

Most mp3s are encoded at 128kb/s... kb/s means kilobytes per second. So these types of files require 128kb for every second of audio.

For stereo mp3's this usually works out to about 1 megabyte per minute. So if your tune is 4 minutes long, count on 4 megabytes

1 megabyte = 1024 kilobytes

1 kilobyte = 1024 bytes

Now, if you are recording from a microphone, you will (hopefully) most likely be recording at much higher bitrates, so those figures will change drastically.

B: Supercomputers

The CPU (Central Processing Unit) is the portion of a computer system that carries out the instructions of a computer program, and is the primary element carrying out the computer's functions. It is the unit that reads and executes program instructions. The data in the instruction tells the processor what to do.

In computers, a unit which delivers information from the computer to an external device or from internal storage to external storage

Charles Babbage and it was first made for military use

Pentium D is a dual core processor, while the Pentium 4 HT is a single core that is capable of running two software threads. More simply put, The Pentium D is 2 people each pulling their own wagons, the Pentium 4 HT is one person pulling 2 wagons with lubricated wheels.

Over all, the Pentium D is better because it is truly dual core, although the Pentium 4 does a great job of trying.

Yes, using a proper splitter is better than a Y cord.

Hardware Theft would consist of people opening up computers and taking parts out of them. Hardware theft also happens in retail stores, when people break open the package and shoplift the item.

A maskable hardware interrupt is one that can be disabled, or masked, by instructions in the CPU.

In the 8085, all interupts except TRAP and (software) RST N can be masked by disabling interrupts, and RST7.5, RST6.5, and RST5.5 can be individually masked with the SIM (Set Interrupt Mask) instruction.

In general, you leave interrupts disabled until one instruction before returning. In the case of the RST*.5 interrupts, you can mask it during interrupt processing and then enable interrupts, allowing other levels to interrupt you again. At the conclusion of the interrupt routine, you would disable interrupts, restore the mask, enable interrupts, and return. If you use this method, you can choose the nesting priority as desired. You determine what mask to set using the RIM (Read Interrupt Mask) instruction and then do bit manipulation before using SIM.

Assuming that you are referring to a modem (analog dial up, or DSL , or Cable Modem - they all use one form or more of QAM or QPSK), then there a radio device that decodes an analog modulated signal (with forward error correction) into digital bits and double-checks their integrity, and then tweaks the digital stream a bit to prepare

it to be placed upon an ethernet bus. Ethernet has it's own special cable and electrical and encryption and protocol specifications also, but to keep things short, the physical uses Manchester codes to send both data and clock signals, and prevent a DC bias from appearing on the line or in the conducting transformer. And, then, after the Physical Layer, there are three more layers of topology to help separate the different stages of passing the message (packet) of data.

(Read more at Wiki's article on Ethernet or the Internet Protocol Suite).

The messages are passed from your Router to your Computer over the Ethernet Cable to the receiving end (your computer) and another radio decodes the modulation and converts the signals back into a stream of bits and bytes that the computer can use (via the communications busses of PCI/PCI-e, etc. and the requesting computer normally puts the received information into RAM so the application can use it.

This is a simplified version of what really goes on. You have your question out-of-order as the switches and communications channel need to be between the source and destination computers.

If I were you, I'd study oup on Ethernet, and Docis 1,Docsis 2 standsards and once you feel comrfortable with that, then you can pick up routing and NAT and Firewalling, and that is where you can get a better functional understanding of how things work. Don't forget that there are plenty of online web resources to help teach you on IP Protocols and Packet Transmission over the internet.

It all depends on what you are converting from. One byte is 8 bits, so if there are 80 bits, you can safely say there are 10 bytes of data.

1024 bytes = 1 kilobyte

1048576 bytes = 1 megabyte

1073741824 bytes = 1 gigabyte

if there are 2 megabytes of data, to find the bytes, multiply by 1048576.

2 x 1048576 = 2097152

Some sources say that 1000 bytes = 1 kilobyte. this is incorrect, as computers work in base 2: that is, 0 and 1. We, as humans, work in base 10: that is 0,1,2,3,4,5,6,7,8,9.
