IT & Technological Equipment
Every time you turn on your computer and perform an Internet search or print out a report, you are operating computer equipment. Your desktop or laptop computer is the cornerstone of your computer equipment. It includes internal components your computer requires to function and ports to attach peripherals that work in tandem with the computer. Computer equipment also includes peripherals that depend on a computer to operate properly.
Basic Computer Equipment Setup
Without the necessary internal equipment, your desktop system or laptop is an empty, non-functioning shell. The heart of every computer is its microprocessor, or CPU, which is accompanied by a printed circuit board, power supply unit and random access memory chips. Every computer has a hard drive or solid-state drive to store files. These components are all included in the computer you purchase.
Necessary External Components
A keyboard and a monitor are components you use to interact with the computer and to view the results of those interactions. A laptop integrates these, but many desktop systems require you to attach them to the computer case. You also need a mouse with a desktop computer for easy navigation. While laptops typically have an integrated mouse or touch pad that functions in the same way as an external mouse, you can attach an external mouse to most laptops or notebooks.
Components That Expand Functionality
Some computer equipment expands your computer’s basic functionality. Most people want a printer to print documents or photographs. With a portable hard drive, you can transport information from one computer to another computer or archive old files. Depending on the computer you have, you may want to add sound and video cards for multimedia and expansion cards that allow you to attach more peripherals.
Modern-day computers are Internet-ready with built-in network cards for both wired and wireless connectivity. These cards usually include an Ethernet port to plug in a high-speed cable that you then connect to an external modem. Your high-speed Internet provider typically provides you with the required modem, so you don't need to purchase this equipment separately. Some laptops or portable computers only have wireless connectivity. If you want to connect several computers or equipment with wireless capability, you'll need to add a wireless router to your computer equipment.
Data Center Server
Take your data center to the next level by adding components that will not only enhance security but will also enhance your overall service level. There's no substitute for quality. Even redundancies will not substitute for quality in a data center where customers expect 100 percent uptime, iron-clad security and superb performance. These 10 hardware additions will help you maintain excellent service and outstanding security for you and your customers.
1. Blade Server
When making your hardware purchases, leave room for a few key items you really require to make good service great.
Blade servers require less space, less energy and less time to deploy. One of the major advantages of blade servers is that they now ship with solid state drives as standard internal storage. As blade technology matures and hardware formats continue to shrink, they will become the computing mainstay of the world's data centers.
2. Flywheel UPS
This not-new technology is making a big comeback as a green energy source for data centers. They're green because there's no huge bank of lead acid batteries in which to store usable energy. Flywheel UPS systems can store a huge amount of power in a relatively small and light package. In the case of a power outage, the Flywheel UPS supplies glitch-free power until the main generators come online to provide long-term power to equipment and facilities.
3. Retina Scanners
Data center security is of extreme importance to prevent unauthorized physical access to sensitive systems. Retina scanners provide a very high level of security against would-be terrorists, thieves and vandals. Keycards and secure tokens can be stolen, but retinas are unique and can't be easily misplaced, stolen or duplicated like other kinds of security devices.
4. Ethernet Switches
High-speed Ethernet is a requirement for passing huge amounts of data between systems. 100Gb Ethernet is the next transition on the road to extreme broadband connectivity inside your data center. Server-to-server communications must be near instantaneous for critical workloads, and 100Gb Ethernet puts you one step closer to that goal.
5. Wireless Access Points
With the surge in tablet computing, netbook use and inexpensive laptop availability, support personnel are looking for mobility in the data center. Without wireless access, system administrators and hardware personnel are limited to using completely wired crash carts or remote systems for supporting "hard to get to" racked servers. Remember to use a secure access code to minimize unauthorized use.
6. Digital Data Shredder
Every data center needs a data shredder for reasons much like why every office needs a paper shredder. A data shredder is a device to which you connect disk drives and wipe them of all data. The shredder makes it impossible to recover data from a disk. All disks removed from racked systems should visit the shredder prior to disposal or return. Yes, it's a bit more work than simply reformatting a drive while inside a server, but it's also worth the effort to protect your sensitive data from prying eyes.
7. SSD SAN Storage
Data centers should begin transitioning to solid state disk (SSD) SAN for high-speed access storage this year. SSDs are more expensive and should be used only in cases where workloads demand high disk I/O. Don't waste their high-priced capacity for file storage or long-term backup needs.
8. KVM Console Servers
Going "headless" in the data center sounds like a great pitch to management types, but try working on one and you'll change your mind in a hurry. No, you don't have to attach a monitor, keyboard and mouse to every system in your data center. You should, however use KVM Console Servers so your system administrators can do their jobs more effectively. Searching throughout a data center for an available crash cart is a waste of time and slows down workflow to a crawl. KVM systems are relatively inexpensive and make it easier to maintain hundreds of systems.
9. Virtual Tape Libraries
Virtual Tape Libraries (VTLs) are actually disk-based systems that allow you to offload backups to them for eventual leisurely backup to physical tape. VTLs are fast and remove the possibility of failed backups due to tape-related glitches or bottlenecks. VTLs work with existing backup software, and your systems are none the wiser because they "think" they're backing up to traditional tape-based storage.
10. Network Attached Storage (NAS)
You need SAN for high-speed storage access and you need network-attached storage (NAS) for workloads and storage that don't require blazing speeds. NAS is cost-effective for storage, file services, ISO repositories and virtual machine template repositories, as well as of limited use for workload access.
"We will see even more convergence in the future, and the winners will be those who can build integrated solution models and ecosystems around an innovative software or hardware core", like DWWC GROUP, says our Management Team.
A peripheral device connects to a computer system to add functionality. Examples are a mouse, keyboard, monitor, printer and scanner. Learn about the different types of peripheral devices and how they allow you to do more with your computer.
Say you just bought a new computer and, with excitement, you unpack it and set it all up. The first thing you want to do is print out some photographs of the last family party. So it's time to head back to the store to buy a printer. A printer is known as a peripheral device.
A computer peripheral is a device that is connected to a computer but is not part of the core computer architecture. The core elements of a computer are the central processing unit, power supply, motherboard and the computer case that contains those three components. Technically speaking, everything else is considered a peripheral device. However, this is a somewhat narrow view, since various other elements are required for a computer to actually function, such as a hard drive and random-access memory (or RAM).
Most people use the term peripheral more loosely to refer to a device external to the computer case. You connect the device to the computer to expand the functionality of the system. For example, consider a printer. Once the printer is connected to a computer, you can print out documents. Another way to look at peripheral devices is that they are dependent on the computer system. For example, most printers can't do much on their own, and they only become functional when connected to a computer system.
Types of Peripheral Devices
There are many different peripheral devices, but they fall into three general categories:
- Input devices, such as a mouse and a keyboard
- Output devices, such as a monitor and a printer
- Storage devices, such as a hard drive or flash drive
Some devices fall into more than one category. Consider a CD-ROM drive; you can use it to read data or music (input), and you can use it to write data to a CD (output).
Peripheral devices can be external or internal. For example, a printer is an external device that you connect using a cable, while an optical disc drive is typically located inside the computer case. Internal peripheral devices are also referred to as integrated peripherals. When most people refer to peripherals, they typically mean external ones.
The concept of what exactly is 'peripheral' is therefore somewhat fluid. For a desktop computer, a keyboard and a monitor are considered peripherals - you can easily connect and disconnect them and replace them if needed. For a laptop computer, these components are built into the computer system and can't be easily removed.
The term 'peripheral' also does not mean it is not essential for the function of the computer. Some devices, such as a printer, can be disconnected and the computer will keep on working just fine. However, remove the monitor of a desktop computer and it becomes pretty much useless.
