Graduate Aptitude Test in Engineering (GATE) is one of the most competitive and toughest exams across the country which is conducted jointly by the Indian Institute of Science (IISc) and seven IITs. The exam offers you a direct gateway for PG admissions in the top colleges of India such as IIT, NIT, etc. Also, the GATE scorecard provides you the job opportunities in Indian PSUs like BHEL, SAIL, GAIL, etc. But…if we look at the numbers, every year around 10 lakh students sit for the GATE Exam, and merely 16-18% of these candidates qualify for the exam....
Multiprocessing is a system that has two or more than one processors. In this, CPUs are added for increasing the computing speed of the system. Because of Multiprocessing, there are many processes that are executed simultaneously. Multiprocessing is further classified into two categories: Symmetric Multiprocessing, Asymmetric Multiprocessing....
1. IP address : An Internet Protocol address (IP address) is the logical address of our network hardware by which other devices identify it in a network. IP address stands for Internet Protocol address which is an unique number or a numerical representation that uniquely identifies a specific interface on the network. Each device that is connected to internet an IP address is assigned to it for its unique identification....
Channel allocation is a process in which a single channel is divided and allotted to multiple users in order to carry user specific tasks. There are user’s quantity may vary every time the process takes place. If there are N number of users and channel is divided into N equal-sized sub channels, Each user is assigned one portion. If the number of users are small and don’t vary at times, then Frequency Division Multiplexing can be used as it is a simple and efficient channel bandwidth allocating technique....
A hazard, if exists, in a digital circuit causes a temporary fluctuation in the output of the circuit. In other words, a hazard in a digital circuit is a temporary disturbance in the ideal operation of the circuit which if given some time, gets resolved itself. These disturbances or fluctuations occur when different paths from the input to output have different delays and due to this fact, changes in input variables do not change the output instantly but do appear at the output after a small delay caused by the circuit-building elements, i.e., logic gates. There are three different kinds of hazards found in digital circuits...
Prerequisite – Critical Section, Process Synchronization, Inter Process Communication The Bakery algorithm is one of the simplest known solutions to the mutual exclusion problem for the general case of N process. Bakery Algorithm is a critical section solution for N processes. The algorithm preserves the first come first serve property....
CPU scheduling is the process of deciding which process will own the CPU to use while another process is suspended. The main function of CPU scheduling is to ensure that whenever the CPU remains idle, the OS has at least selected one of the processes available in the ready-to-use line. Highest Response Ratio Next (HRRN) Scheduling is a part of nonpreemptive CPU scheduling....
The Graduate Aptitude Test for Engineers (GATE) 2024 has been launched by the Indian Institute of Science (IISc), Bangalore recently released an interesting modification to the course syllabus for the year 2024, which is an important change that reflects the evolving environment of technological Development. With the addition of a special paper, aspiring candidates can now explore the worlds of Data Science and Artificial Intelligence (DA) considerably expanding the range of subjects covered by this recognized test. The number of papers in the coming GATE 2024 exam will grow from the previous record of 29 papers to a total of 30 papers....
The Graduate Aptitude Test in Engineering (GATE) is one of the reputed technical exams in India. Every year 7 Indian Institutes of Technology (IITs) and the Indian Institute of Science IISc conduct exams that lead to admission to M.E, M.Tech, Ph.D., and other PSUs. It consists of a 100-mark paper which consists of 65 questions. It is being conducted once a year and the eligibility criteria is a 3rd-year student and above....
