Approach of parallelism used in Data warehouse and OLAP

Approach of parallelism used in Data warehouse and OLAP (Download Reference Research Paper) Processor grouping is used to divide and allocate queries to run parallel and data is divided an assigned to different processors as well. In fact parallelism is implemented in two phases: i) A processor group partitioning (d+1 groups) ii) A physical data […]

Critical Review of Research Paper “Towards Systematically Evaluating Flow-level Anomaly Detection Mechanisms” Download Critical Review by Fahad Mahmood: Objective of this research paper: Objective of this research paper is to identify the hurdles in getting valid and correct statistics of network activity due to privacy concerns, anomaly variability and ground truth. And those hurdles are […]

Benefits of leased line Fee for the connection is fixed monthly rate, can vary with the speed, distance or on package customization basis. Thus it is affordable, faster data transfer rates and are cost-effective. It can be divided into different lines for data and voice communication or use the channel for one high speed data […]

Leased line connections Leased line connection are mostly used in our homes and offices and PTCL (Pakistan Telecommunication Company Limited) telephone connection is one of its examples which is in fact a Point-to-Point connection between two computers set up by a common carrier. Initially it was a normal dial-up connection, a leased line which was […]

Understanding about the concept of LAN topologies I will explain this concept with the help of an example which was my assignment during MCS 3rd Semester. Query: XYZ Company has two offices in Multan. Each office has 40 systems. Network administrator want to connect both offices, as for as he has no budget issues. Following […]

Multiplexing Multiplexing is used in that situation where we have to combine multiple analog message signals or digital data streams over a shared medium instead of dedicated medium. The situation in fact comes up with sharing of the same medium for more than one purpose. Such a way it divides the capacity of the low-level […]

The overall data transmission rate with disk drive latency 7 ms, and a burst bandwidth of 2 MB per second Query: A 4 K byte block of data is read from a disk drive. What is the overall data transmission rate if the disk drive has a latency of 7 ms, and a burst bandwidth […]

The fraction of CPU time handling the data transfer with and without DMA Query: An I/O device transfers data at a rate of 5MB/s over a 100MB/s bus. The data is transferred in 2KB blocks. If the processor operates at 500MHz, and it takes a total of 5000 cycles to handle each DMA request, find […]
