What things can be programmed?
I think you're going to need to put more context into the question before anyone can give you a good answer. Pretty much anything can be programmed. It just takes the right lanaguge and the right logic. anything that has a microprocessor or some set of insturctuions for executing logic and be then told to do something else.
What does the word union mean in the sentence What is the union of A and B?
the word union means together.
What is one disadvantage that objects in LEO have?
Moving data across constellations of other satellites will be complex. Technology for that is still untested
How can you disable a particular part in the source code of CSS?
Put /* block comments */ around it, for example:
style {
attribute: value;
attribute: value;
attribute: value;
}
style {
/* attribute: value; */
attribute: value;
attribute: value;
}
or
style {
/* attribute: value;
attribute: value; */
attribute: value;
}
or
/* style {
attribute: value;
attribute: value;
attribute: value;
} */
And while this won't validate, attribute renaming uses a lot less typing (and I use it myself):
style {
xattribute: value;
attribute: value;
attribute: value;
}
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.

When you input data in a loop within a program the input statement that proceeds the loop is what?
is called a priming input
What is the difference between pl and plx in perl scripting language?
The same reason .doc became .docx.
A real example of parallel execution of sequential programs in a multi-core architecture might be the addition of two matrices...
double a[1000,1000];
double b[1000,1000];
double c[1000,1000];
int i, j;
for (i=0; i<1000; i++) for (j=0; j<1000; j++) c[i,j] = a[i,j] + b[i,j];
...Since each of these 1000000 additions are independent of each other, they could easily be dispatched to multiple threads and run on multiple cores...
for (i1=0; i1<1000; i1+=4) for (j1=0; j1<1000; j1+=4) c[i1,j1] = a[i1,j1] + b[i1,j1];
for (i2=1; i2<1000; i2+=4) for (j2=0; j2<1000; j2+=4) c[i2,j2] = a[i2,j2] + b[i2,j2];
for (i3=2; i3<1000; i3+=4) for (j3=0; j3<1000; j3+=4) c[i3,j3] = a[i3,j3] + b[i3,j3];
for (i4=3; i4<1000; i4+=4) for (j4=0; j4<1000; j4+=4) c[i4,j4] = a[i4,j4] + b[i4,j4];
...with each for loop running in its own thread/core. In fact, most modern optimizing compilers, at the higher optimzation levels, is quite capable of doing this on its own, because they analyze the code and break apart things that can run in different threads automatically.
Describe the function of the instruction set of a CPU?
They tell the CPU where to find the data, when to read it, and what to do with it.
What types of programming languages have the most instruction explosion?
Programming languages differ in the degree of instruction explosion. Even different types of statements within a language vary in the degree of instruction explosion. In general, statements describing mathematical computation have low instruction explosion (10:1 or less), while statements describing I/O operation have high instruction explosion (100:1 or more).
What do critics of artificial intelligence say?
Critics of AI systems argue that such a machine is unrealistic, and even if it were possible, a true artificially intelligent machine is unwanted.
What kind of program is interpreters?
An interpreter is a specialized kind of computer program. This program executes instructions written in a programming language that is not the native coding.
What are the three components to data definition?
Type, name and initial value. If a value is not given and the type supports default construction, a default value is assigned.
What is the best music downloader?
youtube version 3.2.77.0, created 20/04/2011 and only 175kb.depending on your computer internet connectivity, its very fast, user friendly and simple.There are very many versions but this one is the best.
Types of input devices categorized as pointing devices?
An input device is used to transfer information into your computer. When somebody wants to give a presentation on an interactive whiteboard they could use a light pen to touch (that's the pointing bit) the screen to say, open(the input here is 'find this page') a page of further information of an aspect of the presentation topic.
An input device is any peripheral used to provide data and control signals to an information processing system (such as a computer). Input and output devices make up the hardware interface between a computer as a scanneror 6DOFcontroller.
What are some facts about Perl?
Perl is a programming language.
Perl is an interpreted programming language.
Perl is very useful for shell scripts, application programming, and web applications.
Perl is quite easy to learn.
Perl can be, but does not have to be, object-oriented.
Perl was created by Larry Wall.
Perl has probably the best implementation of regular expressions in existence.

How do you say Hi in binary code?
That depends on your string encoding.
In ascii, for example:
H = 72 = 1001000
i = 105 = 1101001
How do you calculate the number of bytes?
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.
Where do you find Font button on the computer?
You can add/remove fonts via Control Panel -> Fonts. Programs that allow font selection will usually provide an interface when you select the text that you wish to format. The interface may be provided by a command menu, a toolbar or a ribbon bar, or by right-clicking the text. For more specific information, consult the program's documentation.
