First, there are two types of prefix when talking about digital information (read bytes): SI prefixes and binary prefixes. SI prefixes SI prefixes are powers of 1,000 (1,0001, 1,0002, 1,0003, etc.): 1 kB = 1 kilobyte = 1,0001 bytes = 1,000 bytes; 1 MB = 1 megabyte = 1,0002 bytes = 1,000,000 bytes; 1 GB = 1 gigabyte = 1,0003 bytes = 1,000,000,000 bytes; ...


The kilobyte is a base 10 measurement, so 1 kilobyte = 10 to the power of 3 = 1000 bytes. Although this is not quite accurate to exactly measure physical data as they are stored in binary which is measured in base 2, and thus the kibibyte was established in 1999 to replace kilobyte when used in computer science context to mean 1024 bytes. Kibibyte is a ...


Speed The numbers are in MHz, and represent the frequency of the clock signal at which the RAM operates (x2 for DDR RAM, so DDR2-800 is running at 400MHz). The DDR means "Double Data Rate" which means it transfers data on both the rising AND falling edges of the signal (instead of just signal on vs. off). So, for example, DDR gives you the effect of 800MHz ...


Currently the use of "KB", "MB", etc to mean anything other than 1000 bytes, 1000 x 1000 bytes, etc is deprecated and contrary to most official standards. The new way of expressing 1024 bytes, 1024 x 1024 bytes, etc is KiB (kibibyte), MiB (mebibyte), etc. It's a mess, and context is essential to understand what is meant. See ...


Probably not, because it would be inconsistent use of the prefixes within a single number. While the SI prefix k stands for 1000, but in IT is often used to mean 1024 (with some advocating binary prefixes), it makes no sense to alternative between these meanings in the same number.


From the Wikipedia: There has been controversy over the meaning of the name, but in early versions of the UNIX Implementation Document from Bell labs, the section for /etc is clearly commented as etcetra directory, as this directory historically held everything that did not belong elsewhere (though in FHS it is clearly restricted to static configuration ...


It stands for "et cetera" that means in Latin "and other things"


A "projector" in Flash is a .swf file fused together with a player as a single executable file.


You are correct in your question. 1 and 4 are correct, 2 and 3 are not. Basically, you define the "thousand" which is either 1000 or 1024 and use that for the multiplications. They don't get swapped around. In base two (binary), the closest you can get to 1000 cleanly is 1024 (2^10). This is how computers actually think about things, so in memory (RAM), ...


Wintel means any Windows operating system running on an Intel x86 architecture. Experience working in a Wintel environment means experience working in a modern desktop Microsoft Windows Operating System, as opposed to other architectures like Mainframe, Unix, or Linux.


So, here's the deal. (Most of) today's computers operate in base 2, not base 10. (Yes, I know there are exceptions, but they really are exceptional cases.) For our (your) purposes, all general purpose computers (and certainly, all consumer use general purpose computers) use base 2 for all internal processing. The fundamental unit is a bit which can be zero ...


Yes, as it's a syntactical disaster. This Wiki article explains the issue and include a table of the "new" words to be used. Here in the real world no one uses those terms. You have to use context to determine which definition you are looking at.


Obviously the actual meaning of "etc." aka "et cetera" has been explained above, however to explain more in relation to *nix... It was intended to be where the miscellaneous files are stored which don't fit into the "categories" of the other root directories, however it has ended up being used mostly for system configuration.


Et cetera Et cetera (in English contexts pronounced /ɛtˈsɛtərə/) is a Latin expression that means "and other things", or "and so forth". It is taken directly from the Latin expression which literally means "and the rest (of such things)" and is a loan-translation of the Greek "καὶ τὰ ἕτερα" (kai ta hetera; "and the other things". The more usual Greek form ...


I found the following information here. The module snmp_index implements an Abstract Data Type (ADT) for an SNMP index structure for SNMP tables. It is implemented as an ets table of the ordered_set data-type, which means that all operations are O(log n). In the table, the key is an ASN.1 OBJECT IDENTIFIER. This index is used to separate ...


So each time he polls the SNMP devices the program shows those devices with different indices. That's not really the case, indices are used to get information on new devices as they are inserted (think hotplugging RAID/RAM/CPU/Virtual Interfaces...), that way you can track a device as soon as the next polling after it was inserted. They SHOULD NOT (as in ...
