Definitions and ExplanationsWhat is RAM Used For? RAM stands for Random Access Memory, which is a type of memory for computers, which, as the name implies, you could randomly access. Any byte of computer memory is potentially accessible without even affected any preceding bytes. It is the abbreviated term, which is commonly used or found in devices [...]
What is a Dual-band Router? A dual-band router is basically a wireless router that works in the two frequencies under the 802.11 wireless standard. Usually dual-band routers operate in the 2.4 GHz and 5GHz frequencies. Dual-band routers are an upgrade to single-band routers using only the 2.4 GHz frequency. Dual-bands offer wider range and faster [...]
CPU Throttling – Learning the What’s and How’s Details CPU throttling is also termed as dynamic frequency scaling. This is a technique in the computer architecture industry where the frequency produced by the microprocessor is automatically adjusted. The main objective for this operation is to conserve the power of your computer. It is also intended [...]
What is Firewire? Firewire is a serial bus interface standard that was created by Apple Inc. in 1986 and standardized in 1995. Also known as IEEE 1394 interface, Firewire is used for high speed communication and regular real-time data transfer. Firewire is usually used with personal computers as well as digital audio and video devices, [...]
What is DIMM? DIMM stands for Dual In-Line Memory Module. It contains a series of Random Access Memory (RAM) chips on a circuit board, and is connected to the motherboard with a 168-pin connector. Earlier memory modules were called SIMMS or Single In-Line Memory Module which had a 32-bit data path and required a 72-pin [...]
What is Ethernet? Ethernet is a local area network (LAN) technology and is actually the most commonly used in computer networking today. The inventor of the technology is no other than Robert Metcalfe. In 1973 to 1975, Ethernet was developed at Xerox PARC, which is a part of Metcalfe’s Ph.D. dissertation. Actually, Metcalfe developed the [...]
What is SXGA? SXGA stands for Super eXtended Graphics Array. It is a display standard for computer monitors and uses 1280 by 1024 pixel resolution. This particular standard is commonly used in computer monitors or screens that are between 17 and 19 inches. Various cellular phones also use SXGA as their own display standard. Graphics [...]
What is Tegra 2? Tegra 2 is a system on a “super” chip developed by NVIDIA for mobile phones and mobile internet devices. It is said to be the fastest chip that can be used for mobile devices as it combines a CPU, memory controller, GPU, north and south bridges into a single super chip. [...]
What is VID? VID stands for Voltage Identification Digital. It is a hardcoded circuit that functions to provide computer CPUs or central processing units with the right voltage supply. Since the computer’s CPU needs varying voltage supplies depending on the applications and programs it processes, a system using digital signals is in place to adjust [...]
What is X86? x86 refers to the family of microprocessors built by Intel since 1978. This microprocessor or CPU architecture involves a set of instructions on how the computer’s CPU or central processing unit will use and/or store data resources like I/O and/or RAM or random access memory. x86 has become the most successful CPU [...]
What is LGA? LGA stands for Land Grid Array and it is used in computer motherboards to serve as the physical interface for microprocessors. It is a type of packaging for integrated circuits in which the pins are placed on sockets, unlike other forms where the pins are connected directly to the ICs. Older forms [...]
What is UPS? UPS stands for Uninterruptible Power Supply and it is basically a backup power source for all machines or items that are connected to it. Usually, computer terminals are attached to a UPS unit to give backup power in cases of power interruptions or blackouts. In most cases, the CPU and monitor is [...]
What is PSW in Microprocessors? PSW stands for “program status word” or the status register that pertains to the current state of a particular processor. It consists of several flag bits for a processor which is why PSW is sometimes referred to as a “flag register”. Some people also refer to the Program Status Word [...]
What is CPU frequency? “CPU frequency” refers to the computer’s clock rate which basically indicates its processing efficiency. Computer CPU’s labeled with higher frequencies or clock rates, for example, are also expected to provide better performance when compared to those with lower CPU frequencies. In simpler terms, the CPU’s frequency relates to its efficiency in [...]
“GPFS,” or “General Parallel File System,” is a file clustering system developed by IBM. This particular file system is considered to be very high-performance because it allows very fast data retrieval and is able to store almost unlimited data in a secure environment. With its reputation as a reliable filing system, many of the world’s [...]
AVI stands for Audio Video Interleave and it refers to a file format with the same initials used for the file extension. AVI files are able to carry multimedia content including audio and video. The first use of AVI files was back in 1992 as part of Microsoft’s Video For Windows system. The use of [...]
KQEMU refers to the Kernel mode of QEMU or Quick Emulator. QEMU is an open-source hardware virtualization program that is capable of emulating the computer’s CPU through a binary system. Using QEMU also allows users to create and run several guest operating systems while the hardware or CPU emulation and/or virtualization is taking place. By [...]
Dfsvc or dfsvc.exe is an executable file that is part of Microsoft’s .NET Framework. This framework basically contains various files and libraries that work together to allow smooth operations between different computer languages. Through the .NET Framework developed for the Windows operating system, a particular language will be able to use codes that are created [...]
CTL files are short for CONTROL files and they correspond to binary files from a particular system or application. In most cases, CONTROL files have .CTL extensions and they typically contain important information like database details or user control information. In the case of the Oracle Database system, CTL files are very important files in [...]
