Summer Slowdown Computer Maintenance Tips

If you’re in the ice cream commercial enterprise, the summer may be your “hottest” season. But, many agencies seem to gradual down over the summer–schools are out and lots of clients and employees are taking part in holidays and circle of relatives time.

Smart enterprise proprietors take advantage of this slowdown to set desires and review enterprise techniques. It’s additionally a tremendous time to preserve your laptop structures and evaluate your era needs for the yr in advance.

Don’t let the summer season slowdown have an effect on your laptop too! Here are 7 guidelines to hold your Windows or Mac computer walking at scorching speeds inside the rapid lane:

1. Uninstall unused applications, and in case you’re a Mac consumer, uninstall unnecessary language files too! Another tip for Mac customers: If you’re the usage of an Intel-based machine, eliminate the unused Power PC binaries, too. While it can appear obvious, we recom­mend which you double test which you surely don’t need those applications earlier than eliminating, particularly, something that looks like it is probably system associated.

2. Clean out your temp documents, tem­porary Internet documents and different junk documents at least once a month. If you are a Windows person, keep in mind to smooth up that registry. Mac customers, clear your cache. You would possibly want to invest in some right 0.33-birthday celebration software program to do those steps to your Windows and Mac machines.

Three. Empty the trash! This applies to both Windows and Mac users alike.

4. Maintain at the least 10-15% free disk area on both Windows and Mac systems. The working system wishes room to maneuver-make sure to provide your machine the gap it needs.

Five. Clean out your e mail. If you ought to grasp directly to it, consider shifting gadgets to an archive folder or report.

6. Defragment your machine. Newer Mac and Windows oper­ating systems (OS X and Windows 7) do no longer require this as lots; however, if you’re still the usage of an older machine, you may see a performance gain from defragmenting your hard disk.

7. Shutdown your system frequently, do not simply placed it to sleep. Not most effective are it “green,” it will perform an entire system reset and provide your laptop a burst of “strength.”

Now which you’ve wiped clean matters up, hold it up! We advocate acting those ordinary mainte­nance responsibilities at least month-to-month-preferably weekly.

In this paper, we are able to cowl the basics on Address Resolution Protocol (ARP), Media Access Control Addresses (MAC), Wireless (WiFi), and layer 2 communications. I wish to explain how a “Man in the Middle Attack” works. The not unusual call for that is ARP poisoning, MAC poisoning, or Spoofing. Before we can get into how the poisoning works we want to find out about how the OSI model works and what happens at layer 2 of the OSI Model. To preserve this simple we are able to most effective scratch the surface at the OSI version to get the idea of ways protocols paintings and speak with each different.

The OSI (open
Systems interconnection) model was advanced with the aid of the International Standards
Organization (ISO) in 1984 in an try and offer some fashionable to the way networking
have to work. It is a theoretical layered model in which the notion of networking
is split into several layers, each of which defines specific capabilities and/or features
. However, this version is simplest preferred guidelines for growing usable community interfaces
and protocols. Sometimes it is able to emerge as very tough to differentiate between every
layer as a few providers do no longer adhere to the model completely. Despite all this the
OSI model has earned the honor of being “the version” upon which all top community protocols
are based totally.

The OSI Model

The OSI Model is based upon 7 layers (Application layer, Presentation Layer, Session
Layer, Transport Layer, Network Layer, Data Link Layer and the Physical layer). For our
proposes we will assessment layer 2 (records link layer), Data Link layer defines the format of
statistics at the community. A network records frame, aka packet, consists of checksum, supply and
vacation spot deal with, and records. The statistics link layer handles the physical and logical
connections to the packet’s destination, the use of a network interface. A host connected to an
Ethernet community could have an Ethernet interface (NIC) to address connections to the
out of doors global, and a loop lower back interface to send packets to itself.
