Identification of Objects in the Software Configuration

  • To control and manage software configuration items, each should be separately named and then organized using an object-oriented approach.
  • Two types of objects can be identified: Basic objects and aggregate objects.
  • A basic object is a unit of information that has been created by a software engineer during analysis, design, code, or test. For example, a basic object might be a section of requirements specification,

Understanding Active Directory, DNS, and Network Security

Intra-Site Automatic Tunnel Addressing Protocol (ISATAP)

Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) is an automatic tunneling protocol used by Windows workstation operating systems that emulates an IPv6 link using an IPv4 network. Active Directory-integrated zones follow a multimaster update model, meaning that all such zones contain a read/write copy of the zone and can make changes to the zone information. Therefore, primary and secondary distinctions are not necessary.

CPU Scheduling Algorithms: A Comprehensive Guide

1. Determining Length of Next CPU Burst

Estimating the length of the next CPU burst is crucial for efficient scheduling. This can be achieved using the length of previous CPU bursts, often employing exponential averaging.

2. Priority Scheduling

Priority scheduling assigns a priority number (integer) to each process. The CPU is allocated to the process with the highest priority (smallest integer = highest priority). Shortest Job First (SJF) is a priority scheduling algorithm where priority is based
