Little's law: A very short introduction

In a firm managers have greater responsibility, he/she have to control everything coming under her/his responsibility. In a system there are certain number of people who works in that system along with it there would be a flow people in and out of the system. And some may spend in the system until their work get done. Manager should keep these things under control. Business managers usually uses a formula to control the flow of customers into and out of their system which was first proposed by American operations research professor John Dutton Little. After his name this formula is known as Little’s formula. This formula has a specific rule which states that the average number of people in a system is equal to the average rate at which people enter into the system multiplied by the average time that an individual spends within it . L=λW where, L=average number of peoples in the system , λ= rate at which average customers arriving, W= average waiting time for a customer In o...

Boot Sector

Booting is a process of loading Operating System(OS) to primary storage(usually Random Access Memory[RAM]), and readying a computer system for use. This process is carried out using a firmware which loads a small program from a special region in in hard disc,floppy disk, optical disc or other storage devices. This region is known as Boot Sector. Boot sector is a first sector on a disk which contains boot record(a machine code) which is loaded into RAM by ROM(BIOS) firmware which in turn loads OS/start-up program into RAM to make the computer into a meaningful machine. There are mainly two types of boot sector: Master Boot Record(MBR): For partitioned storage device MBR is the first sector. Hard disk drives Volume Boot Record(VBR): For non-partitioned storage device VBR is the first sector. Floppy disk, USB flash drive. BIOS does not know about MBR or VBR it simply looks for the first sector of the storage device. VBR which holds the code for booting invoked either directly by ...

Bit Stuffing

Bit stuffing is a widely used process in network and communication protocols as a part of transmission process, also used while sending arbitrary data over a communications channel with bandwidth limits (sometime known as run-length limited (RLL)coding). In communication, to separate one frame from another frame delimiters are used. For most protocols the delimiter usually a sequence of 8-bit pattern are used. In the bit oriented protocol the frame contains sequence of bits representing data. On receiving these frame the layer in the receiver interpret the data part of the frame into usual form. Sometimes the data part are misinterpreted by receiver for delimiter because same pattern used for delimiter may occur in data part. To overcome this, a single bit is stuffed into the data part of the frame to distinguish the delimiter separately. On reaching, receiver remove he stuffed bit from the data part in the frame. For instance if the pattern used for delimiter is 01111110 and in th...

3D matrix

In mathematics the concept of three dimension is considered with X–Y–Z matrix .Matrix, with X, Y and Z-axis denoting the width, height and the depth,respectively, is a three dimensional (3D)structure also known as a 3D matrix. This matrix has been utilized mostly in 3D, Computer Graphics and animation. In computer 3D matrix represent pixel data, provides a big advantage for easy manipulation of data and with help of a simple algorithms changes can be produced in the given pixel data of an image under operation .

Data Boomerang

A data boomerang happens when in-house IT staff are asked to manage a project, along with its data, that was previously deployed on the cloud. There are various reasons that this can happen: the original developers might have moved on to other projects, leaving IT staff to manage resources that used the cloud in testing and have been moved to production in the cloud. IT administrators are tasked with maintaining data that they thought would be hosted in the cloud permanently. By analogy this term, data boomerang,is used with the term "boomerang generation" of, which, young adults moving back in with their parents.
