Cache and main memory both are inboard computer memory. The cache holds the frequently used data. On the other hand, the main memory (RAM) holds the data that is currently in execution. The cache is much faster and more expensive than the main memory. However, both of these computer memories are directly accessible by the processor. Now before going ahead let us discuss what is computer memory. What is a Computer Memory? Memory is a hardware device used to store programs or data. Memory … [Read more...]
Difference Between Modulation and Demodulation
Modulation and demodulation are the techniques important for establishing communication between the devices. Modulation superimposes a weak signal (information) onto a strong carrier signal to get a modulated signal. The modulated signal is further transmitted over a longer distance. Demodulation processes the modulated signal to retrieve the original information. Modulation and demodulation are complementary processes to each other. Thus, modulation is being conducted at the senders’ side … [Read more...]
Difference Between Static and Dynamic Memory Allocation
Static and dynamic memory allocation are the two ways of allocating memory to the computer program. The fundamental difference between these two kinds of memory allocation is that the static memory allocation allocates the memory when the programmer compiles the program. The dynamic memory allocation allocates the memory when the programmer executes the program. What is Memory Allocation? Memory allocation is the task of allocating the memory address to the program (instruction and data). … [Read more...]
Difference Between VPN and DNS
VPN and DNS are the tools that let you access the geo-blocked contents. Although their basic work is different. The VPN provides secure communication between your device and the Internet. On the other hand, the DNS resolves the name of a remote host to its IP address. Initially, we will discuss the differences between VPN and DNS with the help of the comparison. Further, we will discuss the terms VPN and DNS in detail along with the related queries. Content: VPN Vs DNS Comparison … [Read more...]
Difference Between Maskable and Non-Maskable Interrupts
Maskable and non-maskable interrupts are two kinds of interrupts in the CPU. The interrupt that can be ignored by the CPU is the maskable interrupt. The interrupt that cannot be ignored and is reserved for some important events is a non-maskable interrupt. What is Interrupt? An interrupt is a way to break the normal sequencing of the processor in order to perform some specific task. Let us understand interrupts in the operating system using a day to day example. Consider that you are … [Read more...]
Difference Between System Call and System Program
System call and System program play an important role in the functioning of the operating system. As these constructs define what functions the operating system must perform. The system call creates an interface between the user program and the services of the operating system. On the other hand, the system program defines the user interface of the operating system. The system program also creates a suitable environment for a program to develop and execute. For example, the modern … [Read more...]
Difference Between Artificial Neural Network and Biological Neural Network
The significant difference between artificial neural network and biological neural network is that in an artificial neural network the unique functioning memory of the system is placed separately with the processors. On the other hand, in the biological neural network the distributed memory is located inside the neural inter-links. Neural computers are founded on the biological processes of the human neural system (brain). Neural computing involves a extensive parallel processing and … [Read more...]
Difference Between DFD and Flowchart
The DFD (Data Flow Diagram) and Flowchart are presented in a similar manner which makes it confusing, as both constructed with the similar symbols. Though, there is a big difference between the DFD and Flowchart because the DFD is used to specifies the flow of data in the design of the system while flowchart depicts the flow of control of a system. A flowchart is an elementary approach for structuring an explication of a problem which can be implemented in the various branch of knowledge. DFD … [Read more...]
Difference Between CPU and ALU
The CPU and ALU are the parts of the computer, without which a computer would never work well. Here, the main difference between CPU and ALU is that the CPU handle almost all the task that goes in the system while ALU handles the only arithmetic operation of the computer. CPU is intended to use the information in the program memory (instruction) to control the operation of the device. These instructions operate on the data memory and to operate on the data memory the logical arithmetic unit is … [Read more...]
Difference Between LISP and Prolog
The LISP and Prolog are the programming languages intended to serve for the different purpose, where LISP is a functional programming language while Prolog is a completely logic programming language. LISP was considered as the model of computation which is founded on the theory of the recursive functions. Prolog, on the other hand, contains a group of specifications in formal logic which uses first-order predicate calculus. LISP is faster than Prolog as it easily interpreted by … [Read more...]
