A hardwired control unit is a control unit designed using hardware components such as logic gates, flip-flops, decoders etc. Well, there are two ways to design any control unit, it can be designed using hardwired control or using microprogrammed control. Both hardwired and microprogrammed control unit are implemented to generate the control signals required to fetch and … [Read more...] about Hardwired Control Unit
Producer Consumer Problem
The producer-consumer problem which is also known by the term bounded buffer problem is a process synchronization problem. Process synchronization coordinates the execution of processes sharing common resources in such a way that there is no concurrent access to the shared resources to avoid race conditions. In this context, we are going to discuss the producer-consumer … [Read more...] about Producer Consumer Problem
Interprocess Communication (IPC)
Interprocess communication takes place between the cooperating processes. These processes communicate with each other by sharing data and information. Although there occur some issues while establishing interprocess communication. We will discuss those issues along with their solution. We will also discuss ways to achieve interprocess communication. Content: Interprocess … [Read more...] about Interprocess Communication (IPC)
Cloud Ecosystem
Studying the cloud ecosystem will help you determine the environment of the cloud system. The environment consists of interrelated components. These components work in collaboration to facilitate cloud services. The services offered by the cloud ecosystem include infrastructure (IaaS), platform (PaaS), and software (SaaS). However, the cloud ecosystem is not simple. Instead, … [Read more...] about Cloud Ecosystem
System Software
System software is software that allows users to interact with the computer’s hardware. We all are aware that computer understands machine language only. Machine language includes instructions in the form of strings of 0s and 1s. However, machine language is quite difficult for a general user. So, the user instructs its need to the computer in a high-level language that the … [Read more...] about System Software
Data Link Layer Design Issues
Data link layer design issues highlight the problems that network designers must address while designing the data link layer of any networking model. But before understanding these design issues, let us first understand the need for the data link layer. What is Data Link Layer? The data link layer is a layer in the networking model that transforms the raw transmission … [Read more...] about Data Link Layer Design Issues
Cloud Architecture
Cloud architecture defines the working mechanism of cloud computing. The architecture details about all the components that are essential for the working of the cloud. It helps us in understanding how cloud services are made available to the end users. In the section ahead, we will be analyzing the cloud architecture in a layered manner. Also, we will discuss the front and … [Read more...] about Cloud Architecture
Linker and Loader in System Programming
Linker and loader are the two system programs that play a vital role in the execution of a program. A linker combines the target program generated by the language translator with all the external references mentioned in the program. Linker produces a machine language program that does not contain any unresolved external references. This machine language code is an executable … [Read more...] about Linker and Loader in System Programming
Macro in System Programming
Macro in system programming is a feature of a programming language that allows programmers to define an abbreviation for a piece of code. The programmer uses this abbreviation wherever he/she has to repeat the corresponding piece of code in the program. The macro processor scans this source program with macros. Wherever the processor comes across the macro abbreviations, it … [Read more...] about Macro in System Programming
Assembler in Computer
An assembler in a computer is a kind of language processor. It translates the assembly language into machine language. However, the program in assembly language may have some pseudo instructions. These instructions cannot be directly translated to the equivalent machine instruction. In this case, we need to scan the assembly code two or multiple times through the … [Read more...] about Assembler in Computer
