Full meaning of the following term:

MAR- The memory address register holds the address of the instruction which is due to be executed.
MBR- The memory data register/memory buffer register holds the current instructions that are currently being executed.
AC- The accumulator is where arithmetic is done to the data - it is often referred to as a 'calculator' when explaining terms to beginners and novices.
Address Bus- The address bus transports the location of the address to the MAR
Data Bus- The data bus transports the location of the data to the MDR
Program Counter- Holds the address of the next instruction to be executed, ready to be processed as soon as the current instructor has been executed.
IR- The instruction register is where the current instruction is actually executed - it holds the opcode which is the part of the data which outlines the instruction

MAR - Memory Address Register: Holds the address of the instruction that is to be executed

MBR / MDR - Memory Data Register: hold the current instruction

AC - Accumulator: Inside the ALU, provides a place to perform arthimetic calculations

Address Bus - goes from the MAR to the memory

Data Bus - moves the data from memory to MDR

Program Counter - Holds the address of the next instruction

IR - Instruction register: decodes the current instruction

MAR- Memory Address Register
It is used to store the address to access memory.

MBR- Memory Buffer Register
It is used to store information that is being written to and read from.

AC- Accumulator
This is located in the ALU. It is used to store data that is being worked on by the ALU. it is the key register in the data section of the CPU.

Address Bus- the address bus is a bus used for carrying addresses to the processor from the memory and the I/O devices.

Data Bus- the data bus is a bus used for transferring data between the memory, processor and the I/O devices.

Program Counter - it holds the address in memory for the next program instruction to be executed by the processor.

IR- Instruction Register
It holds the instructions being sent to the Memory Buffer Register. When memory is read, the data first goes to the MBR. if the data is an instruction it gets moved to the instruction register(IR)

Mo and Thouheid
MAR- it stands for Memory Address register it is used to store data which is being stored temporarily.
MBR- stand for Memory Buffer Register which is used to store the current information which is being written.

AC- Used to store data that is being worked on by the ALU.

Impact of IT in business: This allows you to communicate with clients around the world.

Program Counter (register and counter) – holds the address in memory of the next program instruction

MAR (Memory Address Register) – Used to store the address to access memory

MBR (Memory Buffer Register) – Used to store information that is being sent to and received from

AC (Accumulator) – Used to store data that is being worked on by the ALU and is key register in the data section of the CPU.

IR – when memory is read, the data first goes to the MBR. If the data is an instruction it gets moved to the IR.
IR (opcode) – most significant bits of the instruction make up the opcode.

what is MAR?
MAR is memory address register, it is used to store the address to access memory.

what is MBR?
MBR is memory buffer register, it is a two-way register that holds data fetched from the memory.

what is AC?
AC is the accumulator, it is a register for short-term intermediate storage of arithmetic and logic data in a computer's CPU

what is the address bus?
A computer bus that is used to transfer data between devices that are identified by the hardware address of the physical memory (the physical address)

what is the data bus?
A computer bus that is composed of a physical set of wires and used to transport data

what is program counter?
A program counter is a register in a computer processor that contains the address of the instruction being executed. As each instruction gets fetched, the program counter then increases its stored value by 1.

what is IR?
IR is the instruction register, a part of the CPU's control unit that holds the instruction being decoded or executed.

I.T can track the amount of sales of a product and order a new batch automatically with no human contact. However, this means people need to be retrained to maintain the system. (point of sale)

some impacts of IT on business:

- storage, the ways that companies and businesses that store and access data. Businesses have been able to change the way that they store their data from paper and folder archives to digital archives and being able to access the data by searching in an organised system.

- communication, communication using IT helps businesses stay up to date, in touch and transfer data. Companies that specialise in telecommunications benefit from this the most since evolving communications open new opportunities for sales.

- education, schools and other educational services benefit from IT since it aids in learning, it can be used for research, writing documents, using educational websites and other uses that can be used to expand knowledge.

- security, businesses are able to keep their systems more secure with cyber security and also physical security such as alarms and cameras

Impact of IT on business
IT helps to save time since the users can carry their work anywhere. they do this by just carrying their mobile devices. they can also work while travelling. You can advertise your ideas to a broader audience a lot quicker than handing out posters / giving leaflets in stores. This also means it is cheaper as you do not need to spend money on storage for these advertising techniques or the printing and paper itself. You are able to work with anyone around the world meaning you aren't only employing people in your area, instead able to employ the best from around the world. Having IT allows a business to have a much larger storage for all of their information where previously they would have filing cabinets full of paper.

IT has many, many, many, many uses in business.

Many business operate only on the internet. Often they use online marketplaces such as amazon or ebay to sell their goods. Companies can also charge for certain services on the internet.

Computers have helped businesses as they can be used to store and quickly gather files.

Charlie - IT in Business Feedback

2017-12-13 12:06:21 UTC

The steep increase of technological advancement has reduced the amount of diversity in business and employment. Jobs taken by the rise of IT have for the most part been labour based, low income or working class" jobs such as delivery driving, construction work, cab driving and cleaning work. Jobs of a higher income or of a more skilled nature are harder to replace with IT but have more inclusion of such. Technology takes low income jobs but aids and enriches high income jobs. One could argue that this effect has created a higher requirement for further education and for a larger percentage of the population to have advanced skill sets. Due to this decline in laborious work there is less diversity in business and those that are less academically inclined or whose skills are more practical will now struggle to find an industry.

Ollie, Wilmer
Communication
IT helped to improve internal and external communication by offering many ways on how information to flow internally and externally.

Productivity
improved business process by saving time, increased and reliable output

Education
With the increasing number of students who have access to internet and other technologies, it has found a way to improve teaching and learning with more efficient and effective approach.

Government
People can visit various types of government websites depending on which department they may need, send an email for their inquiries and it should be responded immediately, without even going anywhere.

IT has speed up how businesses share and transfer information, IT can also help improve a business by collecting data which then can be transformed into information about changes done in the business and how costumers react to this changes.

2017-12-13 12:09:07 UTC

Due to the increasing development in IT, it is making it increasingly easier to replace people jobs with simple pieces of technology that can perform the same tasks in a more efficient manor and can save companies money in the long run as they do not have to pay a machine, only the cost of keeping it running, because there are less man hours needed you can have it carry out functions constantly as it wont get tired and will not need rest.

Business use IT in order to improve their functionality and to help them run faster. IT can be used to manage data, keep a track of profits and databases for stock itineraries and create automatic reports.
