Microprocessors

A microprocessor is the heart of any computer, whether it is a server, a desktop machine, or a laptop. This single chip contains the arithmetic, control, and logic circuitry necessary to interpret and execute computer programs.

Does CPU consist of control?

No. CPU means Central Processing Unit. This is your computer's "tower".

How do you identify processor age?

Right click My Computer, and figure out what type of processor you have first.

(Pentium III, Pentium 4, Athlon, Phenom, etc). This can narrow you down to a small year range that determines the literal age of your processor. For example, the Phenom II have a maximum age range of 2008-2012.

How old it is in terms of years of use? This is something nobody can tell you-- Keep track of this yourself or ask the previous owner of the processor.

What is the average processor speed of a mini computer?

A "mini" computer was the standard of team computing back in the late 70's and through the 80's. I worked on a Prime system and a MassComp system during that time period. I don't recall the clock rate of the Prime 400, but the MassComp was based on the Motorola 68020 and ran about 20MHz. (I might be off a bit as it has been about 30 years...)

By comparison, today's micro-computer (laptops, desktops) boast speeds in excess of 1GHz - some over 2GHz. The problem with raw speed is that the faster you clock the processor, the more power you need to make it go and the hotter it runs. So, to get more power out of modern machines without desoldering the processor from the board, companies have limited the clock speed and gone to dual processors. In fact, my laptop has 4 dual-core processors each running at about 1.5GHz!

How do you get out of safe mode?

When I had this problem I simply uninstalled Winterboard then reinstalled it. Worked fine after that however you do lose any apps that you have with winterboard.

What is a Microprocessor made of?

A microchip is an implant that identifies circuits and are placed under the skin of an animal. It is made of silicon.

Given a page size of 2M and 1G of virtual memory-what is the minimum size of an entry in the process page table-excluding status flags-and how many entries will there be in the process page table?

Given a page size of 2M and 1G of virtual memory, the minimum size of an entry in the process page table is 11 bits, excluding status flags, and there will be 2,048 (64K) entries in the process page table, but see the discussion below for other, probably more useful answers.

The answer depends on the size of physical memory, and on whether or not the page table requires a full base address or not. First of all, a page size of 2mb is not standard - a typical page is 1K to 4K, 4K being using in the Intel processors, but this answer assumes a 2mb page size.

Lets assume the base address in the page table does not require a full base address - a usual configuration. That means the base address is 11 bits. (232 = 1,073,741,824 = 1G. 221 = 2,097,152 = 2M. 32 - 21 = 11) That means the base table field is 11 bits (211 = 2048. However, page table entries are usually rounded up to the nearest byte, 16 bits, so 216 = 65,536 = 64K. This also give room for status and access control bits.

However, the question did not specify the size of physical memory, so the above answer assumed the virtual memory was the same as physical memory, not a usual configuration.

Lets assume a 64GB physical memory size, since you seem to be talking about very large processors. 236 = 68,719,476,736 = 64T. 215 = 32,767 = 32K. 36 - 21 = 15. 15 bits per entry, rounded up to the nearest byte, is still 64K bytes, so we are still talking about 64K.

Although your question did not include status bits, and 1 bit is not enough for a reasonable implementation, and most architectures also use a factor of 2 for their hardware page table, in order to minimize complexity, so we are talking about 128K.

Last, you asked "minimum size". Most processor include a length attribute to the page table, so 64K (128K) is the maximum, and it could be smaller, depending on actual virtual pool size.

If you were the chief information officer of a firm what factors would you consider when selecting secondary storage media for your company's record?

Several factors should be considered when selecting secondary storage media. The first factor is what purpose the media storage is to be used for. The next consideration is the size of the media storage units needed. Price will have a great impact on what selection is made. Speed is another consideration, the buyer should understand how accessible this media will be. Compatibility with other storage units must also be considered. Finally desired portability is another consideration.

In which microprocessor does the concept of pipeline first introduced?

In 8086 pipeline concept was introduced bcoz in 8086 we started using a buffer space which fetches the instruction at the same time when CPU processes

What is the purrpose of a control unit in a processor?

Control unit generates all the control signals like memory read signal,i/o read signal,memory write signal etc

What are the sounds produced during hardware error in computers?

Usually, a computer will generate what's called a beep code when a hardware error occurs. Beep codes are sets of tones that are different per error. They are also different among computer manufacturers. The most common beep code is a somewhat long, steady, beep one time during boot. This usually indicates a video card problem. If you have a problem with your RAM, there will be long, repeating tones that persist until the power is turned off. Some computer models will even audibly tell you what the hardware problem is.

Give the flag settings for af sf zf of cf pf after hexadecimally adding 5b39 to each what a 39a2 b dc49?

The answer to this would be 5b39+39a2=101 1011 0011 1001+11 1001 1010 0010=1001 0100 1101 1011 af=0 sf=1. This would be how this should be worked out to get the correct answer that af=0 and sf=1.

What is called interept classes?

its meaning you taking summer school classes/class for prepare for regent which you failed last year :)

Is your computer 32 bit if it has system32 folder?

Not necessarily - it could just as easily be 64-bit. The presence of the system32 folder is only indicative that you have Windows installed. The same folder exists if you have a 64-bit Operating System installed. If you want to figure out if your system is 32-bit or 64-bit, the easiest way is to go to your system properties: Start -> Control Panel -> System. If it says 64-bit in there somewhere, you are running a 64-bit OS on a 64-bit computer. If it does not, you are running a 32-bit OS, but the computer itself might be 64-bit. In that case, look at the processor type, and if it is not obvious from that description, you can google the description, and you will likely find out whether or not it is 32-bit.
