Hardware
Hardware is the physical components that make up the electronic devices for example keyboards, mice, monitors etc. One main difference between hardware and software is that hardware can be touched and software cannot.
RAM
RAM is an acronym for Random Access Memory. It is a type of memory that is most commonly found in computers and other devices such as printers. There are two types of RAM. Dynamic RAM and static RAM. The two types of RAM differ in the technology they use to hold data, with DRAM being the more common type. In terms of speed, SRAM is faster. DRAM needs to be refreshed thousands of times per second while SRAM does not need to be refreshed, which is what makes it faster than DRAM.

Flash cards
A flash card is a small data storage device that uses a flash memory chip to store data. Flash cards can be quite small in size, with a capacity of a few gigabytes of storage. The memory in these cards is non-volatile, so it does not require a power source to remain intact.
Graphics tablet
A graphics tablet is a piece of a hardware that is a computer input device. It allows you to make hand drawn images similar to that of a pencil and paper. It consists of a touch screen tablet and a stylus to draw.

Monitor
A monitor is like a small version of a TV. It displays the user interface and open programs, allowing the user to interact with the computer. Older computer monitors used Cathode Ray Tubes (CRTs) which made them large and heavy. Modern monitors are built using Liquid Crystal Display (LCD) and are much thinner and lighter.

Software
Software is anything that can be stored electronically. Software is divided into two categories. System software includes the operating system and all the utilities that enable the computer to function. Application software includes programs that do real work for users for example spreadsheets and databases.

Vector based software

Bitmap
Paint
Photo manipulation software

...company’s computer systems are software and hardware. Depending on the type of company, their software and hardware may be high-end, or low-end. In regards to my company, I usually use high-end software and hardware. Running an online retail store requires the use of many programs at once. Although running an online store might not seem like much work, it requires a great deal of attention. Using high-end hardware and software places my company at an advantage. According to Technology Guide 1: Computer Hardware, the author states, “In many industries, exploiting computer hardware is a key to achieving competitive advantage” (Rainer & Cegielski, 2011, Technology Guide 1: Computer Hardware). Business System Specifications In regard to my company’s personal computing software and hardware, we use several devices that run off different applications. One of the hardware devices we use is a phone system called MagicJack. “Magicjack is a device about the size of your thumb which plugs into a USB drive in your computer” (Block, 2010, para. How does the magic work?). This hardware device requires a software application to be installed on our computers that enable a phone to be connected to receive phone-calls. Whenever a customer calls our toll-free number, a dial-pad appears on our screens with the caller’s I.D. displayed. We can either pick up the phone or click ignore on the screen if we are busy. The phone-call is then routed to our voicemail. The software for this device has automatic...

According to Wikipedia.org, the system was sold between 1995 through 1997 and has the following hardware installed, “It was powered by a PowerPC 604processor, a second-generation PowerPC chip which was faster than the earlier PowerPC 601 chip. The 180MP and 200 used the enhanced PowerPC 604e processor. The CPU was connected via a daughterboard, and so could be swapped easily. Available were single-processor cards ranging from 120 to 200 MHz, and a dual processor card with two 180 MHz CPUs. It was the first Macintosh to use the PCI standard, with six PCI slots available, with one always needed for the graphics card.” The exact breakdown of system hardware can be seen at the Apple website at the following link, http://support.apple.com/kb/SP492. The overall operations of the system are great for its age and can even be enhanced with a new program entitled “Leopard” (also available from Apple) that could help the overall performance of the system and was actually the oldest model that is compatible with that program. As for the software, we all know that there are significant differences between workgroup, personal, and enterprise uses such differences can be seen with the different programs each use has to offer, some examples of the differences are business...

...Identify hardware and software needed to secure your choice of networks against all electronic threats. Networking hardware is hardware that is used to help work stations connect to a server. Although there are many different kinds of hardware like bridges, network cards the networking hardware that I have chosen to use in within my company’s network are routers, firewalls and switches. Using both routers and firewalls will help protect not only wireless networks but also those networks that use Ethernet cabling. I chose this hardware because I felt that it’s the best hardware to use when keeping my company’s network safe. The software that I have chosen to use is McAfee Anti-virus security software. This software along with the firewall will keep my company’s network safe and secure. Routers along with firewalls are the top network security hardware needed when it comes to keeping a network almost if not all totally secure. The firewall blocks out any unwanted activity as well block hackers from possibly hacking into our networks and stealing important information that pertains to our company and its customers. Along with the router and firewall networking software also plays a major part. The software is what the firewall uses to create its security barrier over the network. McAfee is one of the top manufacturers when it comes to network security. This software enables the use of not only the internet’s firewall but also the ability to detect viruses, anti-spyware upon...

Fundamentals of Hardware and Software

...SECTION 1 FUNDAMENTALS OF HARDWARE AND SOFTWARE A computer is an electronic device, operating under the control of instructions stored in its memory.  Input – accept data  Processing – manipulate data  Output – produce results from the processing  Storage – store the data and results for future use HARDWARE Hardware is the physical parts of the computer. There are five main components: 1. Central Processing Unit 2. Primary Storage devices 3. Secondary Storage devices 4. Input Devices 5. Output Devices 1. The Central Processing Unit (CPU) is also known as the processor. It is the brain of the computer and converts data into information. CPU speed is measured in Hertz. 1 hertz = 1 clock cycle/machine instruction per second 1 Kilohertz (KHz) = 1000 Hz 1 Megahertz (MHz) = 1000 KHz = 1 000 000 Hz (1 million) 1 Gigahertz (GHz) = 1000 MHz = 1 000 000 000 Hz (1 billion) A CPU with speed of 1 GHz can execute 1 billion machine instructions per second. There are two main parts of the CPU: A: Control unit – This controls the sequencing of operations of the CPU by fetching and decoding instructions and coordinating the input and output devices. B: Arithmetic Logic Unit (ALU) – This manipulates the data. It performs arithmetic operations (including addition, subtraction, division and multiplication and logical operations (including reasoning and performing the comparisons necessary to make decisions). 2. Main Memory/Immediate Access Storage (IMAS)/Primary...

Maintaining and upgrading hardware and software is not an easy especially if the company is fairly large. This past week I had the pleasure to sit down with my company’s IT guy and take a tour of his technological brain; needless to say that was a lot of information to take in. I currently work for Sears Holdings Corp. in the Contractor Services Group division; this division in houses several systems used as personal, workgroup, and enterprise levels. At a personal level each employee uses a PC preloaded with the necessary systems to assist our customers; our PC’s are running Windows XP and we recently upgraded to 19 inch flat panels. Our hardware is very basic and it needs a lot of improvement and/or upgrading to be up-to-date in today’s technology world . Each system is guarded with an enterprise ID given to the employee during the hiring and training process. For example, ServiceBench is one of the systems used to locate service and repairs orders, it shows who the assigned technician is, date of service, if parts have been order or if we have to replace the appliance. As a workgroup we have upgraded to a new a software system called Empower; this system replaced our PRIMS scheduling system. Empower...
