Why Qries is a better platform compared to Quora?
Qries is a knowledge sharing platform where you can put forth queries and voice your opinions and interact with people from all corners of the world sharing their inputs. On comparing Qries to Quora, one will find that Qries comes across as a much simpler and more clutter-free site, making it possible for users to easily breeze through the site.Qries is also equipped with a Hindi version which can have a larger appeal in rural areas as it helps them participate in discussions in a language they are comfortable in.According to a survey conducted by the KPMG-Google study, local languages ...
Read MoreSIM instruction in 8085
In 8085 Instruction set, SIM stands for “SetInterrupt Mask”. It is 1-Byte instruction and it is a multi-purpose instruction. The main uses of SIM instruction are –Masking/unmasking of RST7.5, RST6.5, and RST5.5Reset to 0 RST7.5 flip-flopPerform serial output of dataMnemonics, OperandOpcode(in HEX)BytesSIM301When SIM instruction is executed then the content of theAccumulator decides the action to be taken. So before executing the SIM instruction, it is mandatory to initialize Accumulator with the required value. The meaning and purpose of the various bits of the accumulator when SIM is executed has been depicted below – Note that except bit 5, which is a ...
Read MoreWhy are some languages written left to right?
Actually, we don't have much written historical records of how the writing system has started from right to left or left to right. We believe they were started to avoid smudging from the other side. And mostly they are for the convenience of writing.Here are some languages which are written from left to right.Arabic.Aramaic.Azeri.Dhivehi / Maldivian.Hebrew.Kurdish (Sorani)Persian/Farsi.Urdu.
Read MoreWhat are the differences between Unix and Linux Operating System?
UNIX copyrighted Operating system which is used by IBM AIX, Sun Solaris and HP-UX etc., Most of the UNIX systems are commercial in nature.Linux is considered as UNIX clone. But the traditional companies won't accept "Unix-like" but want the Unix trademark. Linux Is Just a Kernel and not the complete Operating system.When it comes to administration, Linux is considered as most user-friendly operating systems. Unix and Linux use a different set of tools for back up of data. However, they both share some common tools such as tar, dump/restore, and cpio etc.
Read MoreRIM instruction in 8085
In 8085 Instruction set, Read Interrupt Mask. It is a 1-Byte multi-purpose instruction. It is used for the following purposes.To check whether RST7.5, RST6.5, and RST5.5 are masked or not;To check whether interrupts are enabled or not;To check whether RST7.5, RST6.5, or RST5.5 interrupts are pending or not;To perform serial input of data.Mnemonics, OperandOpcode (in HEX)BytesRIM201To get the status information about the interrupt system, Read Interrupt Mask instruction provides status information about interrupt system and this instruction can be used for serial input of data. Through this RIM instruction, 8085 can know which interrupt is masked or unmasked, etc. The ...

Read MoreHistory of the Integrated Circuit
An electronic circuit is a group of electronic components connected for a specific purpose.A simple electronic circuit can be designed easily because it requires few discrete electronic components and connections. However, designing a complex electronic circuit is difficult, as it requires a number of discrete electronic components and their connections. It is also time taking to build such complex circuits and their reliability is also less. These difficulties can be overcome with Integrated Circuits.To define Integrated Circuit (IC) we can consider that If multiple electronic components are interconnected on a single chip of semiconductor material, then that chip is called ...
Read More4-bit microprocessors
In the 4-bit microprocessor or computer architecture will have a data path width or a highest operand width of 4 bits or a nibble. And also these architectures or microprocessors typically will have a matching register file with registers width of 4 bits and 4-8-bit wide addresses.Most of the first microprocessors during the early 1970s had 4-bit word sizes. Both the Intel 4004, the first commercial microprocessor, and the 4040 had a 4-bit word length, but had 8-bit instructions. Some of the first microcontrollers such as the TMS1000 made by Texas Instruments and NEC's μPD751 also had 4-bit words. 4-bit ...
Read More8-bit microprocessors
In computer architecture, 8-bit integers, memory addresses, or other data units are those that are 8 bits (1 octet or 1 Byte) wide. Also, 8-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size. 8-bit is also a generation of microcomputers in which 8-bit microprocessors were the norm. Mainly we can consider 8-bit microprocessor means 8-bit data or information bus.for controlling a CRT display, Federico Faggin and his team at Intel designed a chip produced by Computer Terminals Corporation. Later this chip was called as Datapoint. This chip did not ...
