The following is a brief overview of the differences between standard desktops and workstations as well as the implications for overall performance and productivity as compiled from the editorial resources of CNET, TechRepublic and ZDNet.com. Think Inside the Box A lot of people tend to think of desktop computers and computer workstation as one and the same but that isn’t always the case in terms of power and performance. In fact, many of today’s most demanding workloads and applications for industries such as engineering, entertainment, finance, manufacturing, and science actually require much higher functionality than what traditional desktops have to offer. -
Good Reasons to Use a Desktop Computer
Good reasons to use a desktop computer Why would anyone possibly need a desktop? For most, it goes against all common sense to use a desktop because they're not as convenient and portable as a lap- top, and a laptop does what you need it to do just fine. At the same time, the good ol' bulky, stationary desktop still has a place for many people. Here are good reasons why you might want to use desktop computer. You can upgrade the parts, which is cheaper than buying a new laptop. When a laptop starts to slow down, your only option is to buy a whole new one. Depending on what you need a com- puter for, a new laptop could cost thousands of dollars. That's because you have to buy every single part inside the laptop brand new — the processor, motherboard, RAM, hard drive, and everything else. But most of the parts in your old laptop are probably still fine, and it's usually only the processor (and the motherboard it sits on) that needs upgrading. With a desktop you can easily replace an aging processor (and motherboard) for around $300. That said, all-in-one desktops like the iMac can be a little difficult to upgrade. You get more bang for your buck. Depending on the brand, desktops and laptops with similar specs can often cost the same. Yet, the main differences between the two are the processor and the graphics processor. Most Laptops use the smaller mobile version of a processor model, which often aren't quite as powerful as the full-size desktop versions. -
Secure Shell- Its Significance in Networking (Ssh)
International Journal of Application or Innovation in Engineering & Management (IJAIEM) Web Site: www.ijaiem.org Email: [email protected] Volume 4, Issue 3, March 2015 ISSN 2319 - 4847 SECURE SHELL- ITS SIGNIFICANCE IN NETWORKING (SSH) ANOOSHA GARIMELLA , D.RAKESH KUMAR 1. B. TECH, COMPUTER SCIENCE AND ENGINEERING Student, 3rd year-2nd Semester GITAM UNIVERSITY Visakhapatnam, Andhra Pradesh India 2.Assistant Professor Computer Science and Engineering GITAM UNIVERSITY Visakhapatnam, Andhra Pradesh India ABSTRACT This paper is focused on the evolution of SSH, the need for SSH, working of SSH, its major components and features of SSH. As the number of users over the Internet is increasing, there is a greater threat of your data being vulnerable. Secure Shell (SSH) Protocol provides a secure method for remote login and other secure network services over an insecure network. The SSH protocol has been designed to support many features along with proper security. This architecture with the help of its inbuilt layers which are independent of each other provides user authentication, integrity, and confidentiality, connection- oriented end to end delivery, multiplexes encrypted tunnel into several logical channels, provides datagram delivery across multiple networks and may optionally provide compression. Here, we have also described in detail what every layer of the architecture does along with the connection establishment. Some of the threats which Ssh can encounter, applications, advantages and disadvantages have also been mentioned in this document. Keywords: SSH, Cryptography, Port Forwarding, Secure SSH Tunnel, Key Exchange, IP spoofing, Connection- Hijacking. 1. INTRODUCTION SSH Secure Shell was first created in 1995 by Tatu Ylonen with the release of version 1.0 of SSH Secure Shell and the Internet Draft “The SSH Secure Shell Remote Login Protocol”. -

For several hosts simultaneously, you can monitor each user, session, and process's usage of remote host resources (CPU, memory, etc.) in real-time. Using Terminal Services Manager, you can easily perform various administrative tasks to manage resources and users on a remote host, for example, disconnecting all inactive users, closing inactive users' sessions, or terminating a remote host process. You may use Terminal Services Manager to view information and monitor servers, users, sessions, and processes on servers running Windows Server. You can also perform certain administrative tasks; for example, you can disconnect or log off users from their Remote Desktop Services sessions.

Today Computers Are All Around Us. from Desktop Computers To
Today computers are all around us. From desktop computers to smartphones, they're changing the way that we live our lives. But have you ever asked yourself what exactly is a computer? A computer is an electronic device that manipulates information or data. The computer sees data as ones and zeros but it knows how to combine them into more complex things such as a photograph, a movie, a website, a game and much more... Computers use a combination of hardware and software. Hardware is any physical part of the computer which includes all of the internal components and also the external parts like the monitor and keyboard. Software is any set of instructions that tells the hardware what to do such as a web browser, media player or word processor. Now when most people say computer, they're talking about a personal computer. This can be a desktop computer or a laptop computer which has basically the same capabilities but in a more portable package. Personal computers come in two main styles, PC and Mac. PCs are the most common types, there are many different companies that make them and they usually come with the Microsoft Windows operating system. Macs or Macintosh computers are all made by one company, Apple, and they come with the Mac OS 10 operating system. Computers come in many other shapes and sizes, mobile phones, tablets, game consoles and even TVs have built-in computers, although they may not do everything a desktop or laptop can. There is another type of computer that plays an important role in our lives, servers. -
Desktop Computer Replacement Program Date: May 22, 2019 From: Information Technology Department Presentation Steve Ely, I.T
CITY COUNCIL AGENDA REPORT MEETING DATE: JUNE 4, 2019 ITEM NUMBER: CC-7 SUBJECT: DESKTOP COMPUTER REPLACEMENT PROGRAM DATE: MAY 22, 2019 FROM: INFORMATION TECHNOLOGY DEPARTMENT PRESENTATION STEVE ELY, I.T. DIRECTOR BY: FOR FURTHER INFORMATION STEVE ELY, I.T. DIRECTOR, 714-754-4891 CONTACT: RECOMMENDATION: Staff recommends that the City Council: 1 . Approve the Desktop Computer Replacement Program for the purchase of 435 desktop computers in three phases to replace the computers that have already reached their end-of-life stage. 2. Approve and authorize the Acting City Manager to execute a purchase order with Dell Marketing, LP. (Dell) in the amount of $166,266.27 for completion of the first phase of the Desktop Computer Replacement Program, which includes the purchase of 140 desktop computers. BACKGROUND: The City purchased 435 desktop computers in 2013. These computers have long passed their life expectancy. Their warranty expired in 2016, which makes them prone to issues and causes staff to have to troubleshoot or make repairs as much as they can. In addition to dedicating time for repairs, parts may become obsolete or costly to obtain, resulting in the necessity to purchase new equipment. Desktop computers are the most heavily used pieces of equipment and upgrading them will allow employees to be more efficient in their daily duties and provide the assurance that data and information will not be lost due to aging equipment. ANALYSIS: Many department computers have exceeded their useful life and become inefficient in performing normal functions. Over time, these resources wear, age, 1 and/or become obsolete, causing performance degradation, excessive support and repair activity, and loss of reliability.
