b) Does not give a good return on the investment.
c) Is not based on an assessment of its potential value.
d) Is viewed by these companies as an important business investment.

Find words from the passage which mean the same as the following:

i Examining/studying all details (para 1)
ii Buying (para 1)
iii Necessary (para 2)
iv Important/precious (para 3)
v A special instinctive aptitude for doing something well (last para)

Read the passage carefully and answer the questions given below:
Every market activity is an investment in time, energy and money. Few companies would spend a large sum of money on, say, a purchase of capital equipment without a full investigation into why it is needed, the choices available, and the expected return on what has been spent. Yet every year the vast majority of companies invest a large amount of money in marketing actions without knowing what their financial worth to the company or likely return will be. By introducing the discipline arising from market planning, a company should be able to ensure that the costs of marketing planning show a reasonable return and are calculated in the same way as all other business investments. Many managers believe that the costs of marketing form an additional expense that has to be accepted in order to sell their goods. Whilst it is true that many companies use certain tools of marketing for this purpose, it is also true that the most successful companies accept marketing as an essential part of the company’s total commercial operation, for it is an essential cost in the same way as production or finance. Companies often avoid planning marketing procedures in detail because of the effort needed to express their forward policy in a written form. Managers commonly consider that their time is too valuable to spend on anything other than urgent operational problems. In fact, the manager who spends his time on dealing with current administrative detail is almost certain to have ignored proper planning in the past. For, if properly prepared, the marketing plan will contain sufficient details of the company’s policy and operational strategy for the work to be done by an assistant. As the many alternative courses of action are programmed, the assistant takes any action or decisions which are appropriate. Only unusual situations need be dealt with by the manager. The first step in preparing a marketing plan is that of producing the information necessary for decision making. Usually, a company will have within its own administration and control system the raw material necessary for the plan’s 9 foundations. In addition, there is plenty of published information which is made available by government departments, institutions and the press. Marketing research is yet to be fully exploited by the majority of companies. It has so far only been used by companies that have recognized that their existing information sources are inadequate. Because of the scale of operations that now confronts the typical businessman, it is essential that investment decisions are based upon relevant information, so reducing the business risk. For a marketing-oriented activity to produce lasting results, the entire operation has to be systematically planned. By producing basic information in written form and establishing aims for the future, the company is creating standards against which actual performance can be measured. Documentation of detailed policy actions then provides the basis for controlling the company’s operation. Future trends may be predicted through the investigation of all factors likely to influence company results. A good marketing plan is therefore essential to a company’s successful development, but so is an effective marketing manager. He must be capable of identifying the parameters for market research and interpreting the data produced so that he can quantify the existing and potential needs of customers. Someone with an eye for style in packaging and product promotion is also a valuable asset. In an ideal world, the manager would possess all these abilities; however, they may be useless if not combined with the real love of and natural flair for the job which allow him sometimes to ignore the rational evidence and act instinctively

A computer has a single core processor having 8 General purpose registers and 8 additional special purpose registers. The machine has 64 KB RAM. The size of each register and memory word is 16 bits each. An instruction of the machine is of fixed length and is equal to two memory words. Each instruction of the machine has two operands – one memory operand and second register operand. Memory operand uses direct addressing; however, register operand can use either register direct or register indirect addressing. (Please note that if register operand uses indirect addressing, then stated register contains the address of the operand in the memory.) An instruction of a machine consists of operation code bits, One addressing mode bit and one register operand and one memory operand. The addressing mode bit specifies addressing mode as:

Addressing mode bit |Register Operand | Memory Operand
0 Indirect Direct
1 Direct Direct

Five of the special purpose registers perform the task as Program Counter (PC), Accumulator (AC), Memory Address Register (MAR), Data Register (DR) and Flag registers (FR).

Hard Disk

Hard Disk is a drive, which provides you to store your data for a long time. All your personal data like music, images, videos and files are saved by hard disk. Its basic measuring units are Gigabytes (GB) and Terabytes (TB). You can uninstall and save new data according to your demand. In case of more storage requirement, you can use external hard disk drive as well. Seagate, Toshiba and Western Digital are largest manufacturers of internal hard disk while external hard disk are largely manufactured by ADATA, Freecom, LG, Samsung and Toshiba.

RAM:

RAM is the acronym of Random Access Memory, which is used for storage of computer data, not your personal data. This device is used to read and write data. It temporary stores the computer memory and keep it until system is on and will erased it after your system go shutdown. RAM has two types SRAM (static RAM) and DRAM (dynamic RAM). It is available from 256MB to 8GB sizes. With increase in RAM size system will be able to perform faster than before.

Key Differences(RAM Faster then Hard Disk)

All data you stored on hard disk are permanently saved during usage and after shutdown. While RAM keeps memory until system is running. All the memory will be erased automatically after your system switched off.

currently, RAM are available from 256MB to 8GB (recently announced by Seagate). While hard disk size starts where RAM size ends. 10GB to 8TB size hard disk are available in the market.

RAM is just a chip containing some circuits. Hard disk is almost a machine having multiple parts like platters, plastic disc, magnate, writer & reader bar.

If you are running short of hard disk space, you can use external hard disk for your data storage. There is no option for external remove

Whenever we perform some task, memory first comes from RAM instead of hard disk. Hard disk is a secondary mean for circulation of memory.

RAM works faster than hard drive. Basic purpose of RAM is to fast the performance of system. If you have low RAM, your.

A computer program maybe consisting of various functions and computations that it needs to execute...it also consists of instructions and data.. particularly information on which it needs to operate..

there ARE many ways by which a program executes..

in a very primary way.. any program is executed by the required source compiler..
or on a larger basis.. a program is executed via a central processing unit.. usually present within the system..

a computer requires certain programs and data for its proper functioning and this is done through a computer's central processing units..
there is always a sequence in the way the cpu executes any program..
__________________________________

THE INSTRUCTIONS AND THE PROGRAM DATA.. WHILE EXECUTING A PROGRAM.. are always done via the memory unit within the cpu..
thr role of input devices;
input decvices play a vital role during program execution by allowing the user to input data to the system in order to work further on it..
e.g. keyboard mouse

the role of output devices
output devices play their role by providing a platform to the system to display the results of the executed program..they display it on the screen in hard copy as well as in soft copy
e.g. monitor , printer

Human beings are continuously engaged in some activity or other in order to satisfy their unlimited wants. Every day we come across the word 'business' or 'businessman' directly or indirectly. Business has become essential part of modern world.
