7-Zip is a free and open-source file archiver, a utility used to place groups of files within compressed containers known as "archives". It is developed by Igor Pavlov and was first released in 1999. [2] 7-Zip has its own archive format called 7z introduced in 2001 [12], but can read and write several others.
• If you haven't recently restarted your computer or you don't restart your computer very often, we recommend that you restart the computer. This helps clear the internal memory (RAM), which often resolves many issues.
Task Manager, previously known as Windows Task Manager, is a task manager, system monitor, and startup manager included with Microsoft Windows systems. It provides information about computer performance and running software, including names of running processes, CPU and GPU load, commit charge, I/O details, logged-in users, and Windows services.
Disk defragmenters detect computer files whose contents are scattered across several locations on the hard disk and collect the fragments into one contiguous area. Disk formatters prepare a data storage device such as a hard disk, solid-state drive, floppy disk or USB flash drive for initial use. These are often used to permanently erase an ...
A computer's firmware may be manually updated by a user via a small utility program. In contrast, firmware in mass storage devices (hard-disk drives, optical disc drives, flash memory storage e.g. solid state drive) is less frequently updated, even when flash memory (rather than ROM, EEPROM) storage is used for the firmware.
Example components were CPU, tape drives, hard disks, card-readers, and printers. Computers that predominantly used peripherals were characterized as I/O bound . Establishing that a computer is frequently CPU-bound implies that upgrading the CPU or optimizing code will improve the overall computer performance.
An idle computer has a load number of 0 (the idle process is not counted). Each process using or waiting for CPU (the ready queue or run queue) increments the load number by 1. Each process that terminates decrements it by 1. Most UNIX systems count only processes in the running (on CPU) or runnable (waiting for CPU) states.
This technology is still in use today, predominantly in lower-capacity Seagate desktop drives, [8] but has been phased out in 2.5" drives, as well as higher-capacity desktop, NAS, and enterprise drives in favor of load/unload ramps. In general, CSS technology can be prone to increased stiction (the tendency for the heads to stick to the platter ...
