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.

What Is The Slowest Computer Bus?

The slowest computer bus would be a stopped or halted computer bus, since there would be infinite time between operations.

What is the practical limit for modern CPU clock speeds?

One record was set by a user operating an Intel Celeron 360, a whopping 8.24 GHz! However, most people cannot expect to see standard CPU clock speeds exceed about 3.8 GHz, the highest consumer clock speed of a Pentium 4. Rumors of a 4 GHz Pentium 4 in Europe were proven to be untrue, and new dual-, triple-, quad-, and hexa-core processors simply have no need for such ridiculously high speed.

What is central processing unit?

In lay peoples term CPU is the casing which houses your mother board, HDD, CDROM.

Why do we prefer 2's complements?

in 2's Complement there is only one zero: All zeros

In 1's Complement there are two zeros: All zeros, and All ones ("negative" zero).

So you have one less signed number you can represent with the same amount of bits.

For example, with 8 bits, with 2's Complement you can represent -128 to +127 while with 1's complement you can only represent -127 to +127.

Advantages of the Greek number system?

I think you are referring to the Arabic numbering system which is positional. That is to say that each column represents an increasing power of 10 as one moves from right to left.

This was a major departure from other numbering systems for the purposes of performing math (as opposed to just indicating a number).

The Hebrew alphabet (aleph-beis) is a non-positional numbering system in which every letter is assigned a value - aleph - 1, beis - 2, lamed - 30, etc. Here what might appear as a word might actually be a number (since it is unusual to see Hebrew written with vowels).

These Hebrew numbers are often used in Gematria which maps words to numeric values so that additional insight might be gained into the deeper meaning. In Hebrew, the word for wine and the word for secret have the same numeric value and from this stems the expression "when the wine goes in, the secrets come out".

I believe that the Greeks followed the Hebrew pattern where alpha - 1, beta - 2, lambda - 30, etc.

The Greeks via the Christians, performed a similar process on their words for similar reasons.

What does a CPU bus do?

the CPU bus is the connection between the motherboard and the CPU. All data flows through different data bus.

What are the different types of microprocessors?

based on bit of operation at a time

8 bit, 16 bit, 32 bit, 64bit (now days) and etc So far i know, they are Laptop, Desktop, Server and Embedded processors, for example Laptop- Intel Centrino, Desktop- Intel Pentium, Server- Intel Xeon, Atom, Embedde- ARM and classification of microprocessor considering instruction sets they process: RISC - Reduced instruction set computing (oven, AC etc.) CISC - Complex instruction set computing (eg. laptop, desktop processor)

When was the latest computer processor introduced?

Hm.

Introduced as in revealed, or as in sold to the public? As of this moment, the successor to the Intel Haswell architecture and the successor of the AMD Kaveri APU, are most likely latest processors to be mentioned in the technology world, particularly in AMD's case as Kaveri hasn't been released to the public yet.

Haswell is the newest x86 processor released to the public, with ARM processors (Which are typically mobile-computing oriented) having new releases in close proximity. AMD had a refresh of their APU line called Richland recently, and a bit longer ago released Piledriver to the public, which was much earlier in 2013.

Why you using micro controller NoT micro processor?

Microcontroller have inbuilt memory, interrupts, etc. Which you will need to connect externally in microprocessor. Thus, Microcontroller is better than microprocessors

How many bits are contained in the A register of a 8085 CPU?

8085 is a 8 bit microprocessor and so A register which is also known as accumulator is also 8 bit.

What unit can be called the brain of a computer microprocessor?

Control unit .Because it controls or supervises the all the actions of computer by generating control signals .

Transmission from the CPU to the printer is done in form?

Binary. yea binary is right just had 2 double check 2 make sure u were riite!! lol=]

Do you lose saved programs when changing CPU?

No. Changing a CPU is very similar to changing a ram chip, and neither should cause any loss of data or programs stored on the hard drive.

What values can a bit take?

They are binary. They can be High (1) or low (0).

Old joke: There are 10 types of people! Those that understand binary and those that do not.

What unit represents the fastest CPU clock speed?

The gigahertz (GHz) is the largest unit used to represent CPU clock speed.

The fastest frequency ever reached was 8.429 GHz, set by the FX-8150 in September of 2011. A more recent claim has been made of 8.805GHz on the same processor, but it has not been officially validated yet.

When a computer has two or more Central Processing Units it is considered?

if 2 CPU on 1 chip is used its called DUAL CORE if it 4 CPU on one chip its QUAD CORE if it is needed the answer depends on programs you want torun if you using Nero and word and paint and run a gme dual core or quad core is necessary

What are the uses of microcomputer?

answers by EMI IYALLA (student, informatics Singapore) these systems have evolved to what we now know as the pc. since they function as stand alone workstations they have both personal and business applications areas. these areas includes: text edition, spreadsheet preparation, graphics design, accounting, database management etc. (i'm still working on this document)

What are self complimentary codes?

Self complimentary codes are codes which after certain number of digits extends itself by taking the compliment of the previous digits.
