What is thrashing in computer terminology?
Thrashing is a high paging activity. A process is thrashing if it is spending more time with paging rather than execution.
Thrashing is caused by under allocation of the minimum number of pages required by a process, forcing it to continuously page fault. The system can detect thrashing by evaluating the level of CPU utilization as compared to the level of multiprogramming.
Caused by:-
- Global replacement algorithm.
- Under allocation of the minimum number of pages required by a process.
- Very high degree of multiprogramming.
Eliminated by:-
- Reducing level or degree of multiprogramming.
- Use local replacement algorithm.
- While allocating check minimum sufficient frame required for a process.
One kilobyte (kB) is equal to the following:
- 1000 bytes (B)
- 0.001 megabytes (MB)
- 8000 bits
- 8 kilobits (kbit)
- 0.008 megabits (Mbit)
FSB stands for front side bus. It's the "information highway" between the CPU and the other hardware components, like the hard drive. It's bi-directional, too.

Number of characters in a UNIX file name?
It depends on the version of the operating system and how it is configured. You would need to look at the MAX_PATH setting to determine what the exact maximum is for a path name.
In general, you should be able to get at least 255 characters and possibly much more depending on the system.
Mapping function between cache lines and main memory block?
I didn't quite understand your question but I'll answer you anyways :P..
It's known that the main memory is much larger that the cache memory , and we need to transfer a block of instructions to the cache memory to be frequently used by the processor to improve performance and reduce time spent in fetching instructions or data ( dealing with cache memory is much faster than RAM ). for example lets say that a main memory has a 128 data blocks and you need to place them in the cache memory which consists of 32 data blocks? then you have to have sort of technique to place them or MAPPING FUNCTION. And there are plenty of 'em (four mapping techniques as far as i know) i will just mention them without getting into details:
Direct mapping , fully-associative, set-associative and n-way set associative.
if you need more details just ask.
greetings
Can you please provide some help over Direct mapping , fully-associative, set-associative and n-way set associative
Thanx
What does it mean by encapsulation?
Encapsulation makes class fields private, preventing access to it from outside of the class. Essentially, this data is hidden from the rest of the program. It is possible to allow access to the fields via public methods.
A computer that is small enough to fit in the palm of one's hand
When you email someone and you find an address after cc: that means they were sent a copy of the email. cc is an abbreviation for carbon copy - a method of making duplicates of a written piece of paper by placing a sheet of transferable ink "carbon" between the original and the copy which is underneath. This was in wide use before the invention of photocopying machines.
Via mail means that something was sent using the US Postal Service. Via Mail means by using any of the services that the USPS uses.
A kilobyte (or a k) is 1024 bytes, so 16k is 16*1024 bytes or 16384 bytes.
What does .me stand for in a URL?

What are ill-effects of software piracy?
every time you purchase legitimate software, you are giving money to the sales people, shipping agents, manufacturer, designer, developer, etcetc
every pirated software program stops each of these people earning their share of the money from the software, however, some people may argue that they would never use it if they had to pay for it, & only use it if its free, but its still illegal if it has a copyright.
also to remember, if the developer & designer don't get paid for their work, they may no longer produce any products, & that leads to no new developments, & we all get stuck with old technology (yeah, like that's going to happen!)
How do you design a database management system for stock exchange?
You would need at the very least 3 tables.
1. TblCompany
Assign them a unique ID.
Ticker (Symbol)
CompanyName
Industry
Sector
2. tblDate
OpenedStockDays
...
...
3. TransactionTable
Ticker
OpenedStockDays
Open
High
Low
Close
Volume
make sure to link them properly and to always set a primary key for each table.
MHz and GHz are a measure of frequency. In science frequency = 1/time for one cycle.
If a wave takes 0.5 seconds to complete a wave, the frequency is 2 Hz.
MHz and GHz in computers measure the same thing. It measures the frequency of the processor (ie, how many cycles it completes in a set time)
again, if each cycles takes 0.5 seconds, then your computing speed is 2 Hz.
a GHz (giga hertz) is equal to 1000 Mhz (mega hertz)
a MHz is equal to 1,000,000 Hz.
how is mhz and ghz is measured?
What is the function of a data cable inside a computer case?
Data cables (called ata cables or serial or SCSI) simply transfer data from one device to the motherboard inside or even to another device hooked up to the same cable. An example would be a cdrom drive could transfer data for listening to music via the data cable and the motherboard would process it and produce sound via speakers.
There may be multiple popular meanings for EDPS, with the most popular being that of Electronic Data Processing System. Please see the related link for other meanings.
Is 4.4 MB a high resolution photo?
It depends on the purpose. 400 pixel resolution on a printer is about average. It produces clean documents. However, 1200 pixel resolution will generate much smoother details.
What is used to store instructions and data when they are not being used in memory?
Hard drive. Data is pulled from the drive and stored into the memory for quick access.
