SYSTEM SOFTWARE AND APPLICATION SOFTWARE Computer performance - is the amount of work accomplished by a computer system COMPUTER PERFORMANCE Computer storage that keeps the data or its contents regardless if the power is turned off or if the storage device is moved to another computer. The most commonly used permanent storage is the computer hard drive. Permanent storage INPUT AND OUTPUT DEVICES Computer hardware Computer hardware (or simply hardware in computing contexts) is the collection of physical elements that constitutes a computer system.

Feb 21, 2018 - Peopleware refers to the role of people in the computing process. While and make up a computer system, both are designed to be used.

• A Software is the collection of instructions, Programing or codding, which we can only see, Feel or can imagin about it`s logic. A Hardware is the Physical component.
• Also known as Data Warehouse or Enterprise Data Warehouse It is a central repository of data which is created by integrating data from multiple disparate sources.

Computer hardware is the physical parts or components of a computer, such as the monitor, keyboard, computer data storage, hard disk drive(HDD), graphic cards, sound cards, memory (RAM), motherboard, and so on, all of which are tangible physical objects. By contrast, software is instructions that can be stored and run by hardware. Hardware/Software/Peopleware and IT It is the physical components of the computer. It also refers to the tangible parts of the computer system. Hardware computer performance may involve one or more of the following:. Short response time for a given piece of work.

High throughput (rate of processing work). Low utilization of computing resource(s). High availability of the computing system or application. Fast (or highly compact) data compression and decompression. High bandwidth.

Short data transmission time HARDWARE SOFTWARE PEOPLEWARE THREE BASIC COMPONENTS OF COMPUTER The operating system, or OS, is the basic software for running any computer. It works together with other software for video streaming, music playback, word processing, Internet browsing and more. Software It is a human being that has to input instructions in order for the computer to execute the task. Peopleware Information technology (IT) is the application of computers to store, retrieve, transmit and manipulate data Information technology (IT) RAM- random access memory DVD FLOPPY DISK HARD DISK DRIVE Loplop, Rose Christine Doroteo, Vanity Mae Gaco, Ron Joven Austria, Adrian Alvarez, Marc Lawrence Members: An input device is any hardware device that sends data to a computer, allowing you to interact with and control the computer.

The most commonly used input devices on a computer are the keyboard and mouse. A barcode reader (BCR) also known as a point of sale (POS) scanner is a hardware device capable of reading a barcode. It can also print out the details of the product or log information about that product into a database.

Biometrics is the identification of a person by the measurement of their biological features. Scanner is an input device which works more like a photocopy machine. It is used when some information is available on a paper and it is to be transferred to the hard disc of the computer for further manipulation. Scanner captures images from the source which are then converted into the digital form that can be stored on the disc. These images can be edited before they are printed.

Joystick (game controller device) is a remote control device which is used in gaming purpose. Input/Output Device Alternatively referred to as I/O, Input/output is any software or hardware device that is designed to send and receive data to and from a computer hardware component Secure Digital Card, the SD Card is one of the more common types of memory cards used with electronics.

The SD technology is used by over 400 brands of electronic equipment and over 8000 different models, including digital cameras and cell phones. Other Input Devices An output device is any peripheral that receives data from a computer, usually for display, projection, or physical reproduction Monitors We use this to view the work we're doing at the time or to view a finished product. We may also use it to view videos or photos we've taken or found online.

Printers are used to create a tangible product to look at away from a monitor. Speaker, Headphone Computer speaker is the other output device which is used to hear a sound played by a computer. Plotters are used to draw different designs of buildings or internal structure of machines. Mostly Engineers and Architects use plotters. Projector - An output device that displays what is in a computer in a larger scale. Modem that connects to the Internet and can send and receive information. Examples: A hard disk drive (sometimes abbreviated as Hard drive, HD, or HDD) is a non-volatile memory hardware device that permanently stores and retrieves information.

A hard drive can be used to store just about any type of data, including pictures, music, videos, and text documents. Alternatively referred to as a cd writer, CD-WO(Write once), WORM (Write Once Read Many) drive. CD-R is short for CD-Recordable and is a writable disc and drive that is capable of having information written to the disc once and then having that disc read many times after that.

A touchscreen is a monitor or other flat surface with a sensitive panel directly on the screen that registers the touch of a finger as an input. A touchscreen allows the user to interact with a device without a mouse or keyboard and is used withsmartphones, tablets, computer screens, and information kiosks. Types of Memory: Memory is an essential element of a computer. Without its memory, a computer is of hardly any use. Memory plays an important role in saving and retrieving data. The performance of the computer system depends upon the size of the memory.

Short for Digital Versatile Disc or Digital Video Disc, aDVD or DVD-ROM is a disc capable of storing large amounts of data on one disc the size of a standard Compact Disc. MEMORY TYPES 1. Primary Memory / Volatile Memory: Primary Memory is internal memory of the computer. RAM AND ROM both form part of primary memory.

The primary memory provides main working space to the computer 1. Primary Memory / Volatile Memory 2. Secondary Memory / Non Volatile Memory. Random Access Memory (RAM) Read Only Memory (ROM): PROM EPROM Cache Memory Registers Random Access Memory (RAM). Structure A set of memory chips, each of them is an integrated circuit (IC) made of millions of transistors and capacitors. Volatile - their state is lost or reset when power is removed from the system.

Usage: Holds data/application programs from input devices or storages. Capacity: Determines the number and size of the program can be run at the same time as well as the amount of data that can be processed immediately.

Bus: processing speed Magnetic Tape Magnetic Disk Optical Disk 2. Secondary Memory / Non-Volatile Memory: Secondary memory is external and permanent in nature. The secondary memory is concerned with magnetic memory. Secondary memory can be stored on storage media like floppy disks, magnetic disks, magnetic tapes, This memory can also be stored optically on Optical disks - CD-ROM. Read only memory (ROM). Has contents which are fixed when the chip H manufactured. Hobs the bootstrap loader part of the operating system.

Retains its data when the computer is switched off Examples: Floppy discs A floppy disk is a data storage medium that is composed of a disk of thin, flexible floppy)magnetic storage medium encased in a squareor rectangular plastic shell. Floppy disks are read and written by a floppy disk drive A hard disk drive is the device used to store large amounts of digital information in computers and related equipment. Hard disk drives are used to store operating systems, software and working data. These are suitable for any application which requires very fast access to data for both reading and writing to. However, Hard disk drives may not be suitable for applications which need portability. Optical backing storage media such as CDs and DVDs.

Optical disk is an electronic data storage medium from w/c data is read and written to by using a low-powered laser beam. It is a flat, circular, plastic or glass disk on w/c data is stored in the form of light and dark pits.

There are three basic types of optical disks: Read-only optical disks, Write once read many optical disks and Rewritable Optical disks. CD and DVD A memory card or flash memory card is a solid-state electronic flash memory data storage device used with digital cameras, handheld and Mobile computers, telephones, music players, video game consoles, and other electronics.

Portable hard discs Portable hard discs are good fun because you can carry data about all over the place and transfer information, programs, pictures, etc between computers. Magnetic tapes Magnetic tape has been used for data storage for over 50 years. When storing large amounts of data, tape can be substantially less expensive than disk or other data storage options. Tape storage has always been used with large computer systems.

Modern usage is primarily as a high capacity medium for backups and archives. USB flash drives are typically removable and rewritable, much smaller than a floppy disk.

Storage capacities typically range from 64 MB to 64 GB. USB flash drives offer potential advantages over other portable storage devices, particularly the floppy disk. Fixed hard discs The smallest unit of measurement used for measuring data is a bit. A single bit can have a value of either 0 or 1.

Computer performance metrics (things to measure) include:. Response time -Service time - How long it takes to do the work requested.Wait time - How long the request has to wait for requests queued ahead of it before it gets to run.Transmission time – How long it takes to move the request to the computer doing the work and the response back to the requestor. Channel capacity. Latency. Scalability. Power consumption.

Size and weight. What are some examples of software or the different types of computer software?.

PEOPLEWARE - anything that has to do with the role of people in the development or use of computer software and hardware systems. SOFTWARE - the programs and other operating information used by a computer. UNDERSTANDING SOFTWARE AND PEOPLEWARE What is SYSTEM SOFTWARE? System software is a type of computer program that is designed to run a computer’s hardware and application programs. If we think of the computer system as a layered model, the system software is the interface between the hardware and user applications. Example Of System Software. The OPERATING SYSTEM (OS) is the best-known example of system software.

The OS manages all the other programs in a computer. The BIOS (basic input/output system) gets the computer system started after you turn it on and manages the data flow between the operating system and attached devices such as the hard disk, video adapter, keyboard, mouse, and printer.

The BOOT program loads the operating system into the computer's main memory or random access memory (RAM). An ASSEMBLER takes basic computer instructions and converts them into a pattern of bits that the computer's processor can use to perform its basic operations. A DEVICE DRIVER controls a particular type of device that is attached to your computer, such as a keyboard or a mouse. The driver program converts the more general input/output instructions of the operating system to messages that the device type can understand. What is APPLICATION SOFTWARE? An application program (app or application for short) is a computer program designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user. Examples of an application include a word processor, a spreadsheet, an accounting application, a web browser, a media player, an aeronautical flight simulator, a console game or a photo editor.

Software

This article will help explain the terms usually used in Networking such as Driver, Firmware, Hardware, Software and Utility. Hardware is any physical electronic device. Computers, adapter cards and Ethernet cables are examples. Software is a broad term for the programs running on hardware. Familiar kinds of software are operating systems, which provide overall control for computer hardware, and applications, which are optional programs used for a particular job. Software resides on disks and is brought into memory when it is needed. Often a distinction is drawn between software and firmware.

Firmware is software that is semi-permanently placed in hardware. It does not disappear when hardware is powered off, and is often changed by special installation processes or with administration tools. The memory firmware uses is very fast — making it ideal for controlling hardware where performance is important.

For example, NETGEAR routers filter using firmware, which tends to make them faster than a PC or Macintosh performing a similar function. A software or firmware upgrade makes a permanent change — usually an improvement in features, in performance, or to correct errors. Beta software or firmware is an upgrade that has not been thoroughly tested. Some situations that can only be tested by putting equipment in the actual situation it will work.

Beta software and firmware is far more likely to have bugs than the polished final versions. Beta firmware may change rapidly when errors are found and corrected by the makers.

For these reasons NETGEAR makes beta software and firmware available, but cannot provide technical support for it. A driver is software and/or firmware that controls hardware. Often it connects an operating system with specific hardware devices. For example, there are drivers for every card and disk in your computer. Each driver is written for a specific operating system — for example Windows XP or Macintosh OS X. Therefore, to use a card in your computer, you must use a driver that matches the device and also your operating system.

Drivers can be enhanced, for example, when new operating systems come out. Eventually hardware becomes so old it is no longer economical or practical to produce new drivers for it. Sometimes the words software, firmware and driver are used interchangably, so don't be thrown off if somebody uses the word 'software' when you expected to hear 'driver', or vice versa. A utility is software used for the limited purpose of changing the overall behavior of hardware or other software. (For example configuring your browser to accept cookies.) Utilities tend to be used once or twice at most.

On a typical computer or router, there will be utilities users never touch at all. If a utility is not used, default values are used, instead. GearHead Support for Home Users GearHead Support is a technical support service for NETGEAR devices and all other connected devices in your home.

Advanced remote support tools are used to fix issues on any of your devices. The service includes support for the following:. Desktop and Notebook PCs, Wired and Wireless Routers, Modems, Printers, Scanners, Fax Machines, USB devices and Sound Cards.
