Cache memory and register both are the memory units of the computer. But they are not the same in terms of speed, size, access time, etc. Cache memory is an individual memory unit that stores the data that has been used recently by the processor. On the other hand, the register is a high-speed storage element that holds the data that the CPU is currently processing. Whenever the processor fetches any instruction or the associated data from the main memory into the processor chip (registers), … [Read more...]
Difference Between Internet and Ethernet
Internet and Ethernet both are the communication standards that enable connectivity between the communicating devices. Internet is a network of networks that gradually forms a wide area network (WAN). Meanwhile, Ethernet is a hardwired connection between the computers that gradually forms a local area network (LAN). The Internet is a global network connecting users across the world. However, Ethernet is used to connect your device to the local area network. Although you can even use Ethernet … [Read more...]
Difference Between Server and Database
The basic difference between a server and a database is that server is a computer program that runs to provide services to other computer programs or devices. On the other hand, the database is an application that stores data in an organized form and can be retrieved by the user with the help of a query. In the section ahead, we will be discussing the differences between server and database. Content: Server Vs Database Comparison Chart What is Server? What is Server Used for? … [Read more...]
Difference Between DSL and ADSL
DSL and ADSL are the technologies adopted by telecom companies to facilitate faster data transmission. DSL (Digital Subscriber Line) is a set of technologies, among which ADSL is one. Although ADSL is a subset of DSL technologies we will try to identify some of the differences between these two. We will also be discussing about both techniques in detail. Content: DSL Vs ADSL Comparison Chart What is DSL? DSL Modem WhatisADSL? ADSL Broadband Echo Cancellation … [Read more...]
Difference Between Cache and Main Memory
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...]
